Chiller Ideas In Warm Climates

In the hot summer time, the efficiency of any industrial liquid chiller is reduced. Read on to learn more about keeping your chiller working smoothly when the sun comes out!

Water-Cooled Chillers

  • Make sure the plant water system is operating correctly.
  • Most chillers require three gallons per minute of cooling water for every ton of system capacity delivered at a pressure differential of 20 pounds per square inch.
  • Keep it clean by phsicially cleaning the condenser tubes or utilize a chemical cleaning system. The slightest build up of scale can have a dramatic effect on performance.
  • Make sure the pressure activated water modeling valve is opened fully when required.

Air-Cooled Water Chillers

  • Utilize a non-acid based commercial coil cleaning system to keep the condenser coil clean and the fins properly combed to allow proper airflow.
  • Make sure the space is adequate around the chiller to ensure thecorrect amount of airflow. Most need four to five feet of clearance space on the air inlet side and clear space above as well as four to five feet of clearance space for units that discharge on the side.
  • Ensure the ventilation is adequate so air recirculating is prevented.
  • Make sure fan blades, motors and blowers are working correctly and well maintained.

How To Clean A Cooling Tower

Cooling towers are a crucial aspect of the HVAC system across numerous industries. Regular cooling tower cleanings are a necessity to ensure proper operation. So, how does the cleaning process work? Let’s take a look at five simple steps below.

Step 1. Inspect Cooling Tower

The first step towards properly cleaning the tower is by doing a complete inspection of the area.

  • Inspect the tower at least every month, but especially the day of the cleaning.
  • Inspections can reveal areas that need to be focused on during cleanup.
  • Check to see if the fill media has been fouled up by any buildup.
  • Finally, check the hot water basin for sludge.

Step 2. Protect Yourself

Make sure to protect yourself from any hazards you may encounter during the cleaning process.

  • Turn off pumps and fans using OSHA lockout/tagout procedures.
  • The heat and moisture coming from the tower poses threats, as well.
  • You need to wear eye protection and a mask with the appropriate filter grade.

Step 3. Bacteria Treatment

Bacteria and fungus can grow and thrive in cooling towers, which can cause harm or illness in humans.

  • Disinfect the area, thoroughly.
  • Ensure you disinfect with proper chemistry prior to cleaning.
  • Spray the tower’s surfaces and water any chemical compound.
  • This also helps deter any further growth in the future.

Step 4. Remove Sludge

Locate the basin, as this is the most common area where sludge is discovered.

  • Specialized vacuums can be used to remove sludge buildup.
  • If you do not have such vacuums, a cooling tower cleaning company can provide one.

Step 5. Fix Fouling/Clogs

The most important phase of the heat exchange within the tower will take place in the fill media.

  • When fill media becomes clogged, the cooling will not take place as it should.
  • Clean the fill media with detergent.
  • Replace the fill, if necessary.
  • Neglecting any fill media buildup can result in higher electricity bills.

How Much Does Professional Cooling Tower Cleaning Cost?

On average, a typical cooling tower cleaning project will cost $10,000. Projects will range from $5,000-$15,000, according to HOH Water Technology.  Costs will vary based on a few factors, including the size/complexity of the systems and amount of remediation needed.

Cooling Tower Repair

Climate control is crucial in modern homes and residential buildings, especially in hot or cold areas. Regulating climate can be an energy intensive task with most HVAC equipment featuring numerous technical components. That’s why a professional company is needed for any important cooling tower repairs.

Cooling towers are used in combination with commercial chillers to eliminate any unwanted heat that is generated during operation. Many of the components focus on proper extraction of heat, especially in most modern units. Whenever a cooling tower ceases to function properly, it’s best to contact the professionals right away.

Cooling Tower Overview

Cooling towers are generally found in large power plants and manufacturer buildings. The towers can vary in size, though. Cooling towers can also be spotted on mall, university and hospital rooftops. They are commonly found inside an HVAC system, used to cool the inside of a building. The cooling load is determined by the amount of space in the building and/or location which needs the heat extracted. Humidity of the air is also accounted for, as cooling towers in Florida will differ from a tower located in the dry heat of Arizona.

Evaportaive cooling is a cycle that turns cooling evaporating water into air. This is a natural process, and one that can be seen utilized often in athletics. Next time you watch any sort of game, scan the sidelines for misters used to cool the players down after competing. Another example would be what happens the moment one steps out of the shower. The water on the skin quickly evaporates and pulls the heat from the body. We then feel the cooling sensation taking over.

Simply put, cooling towers are large boxes equipped to maximize the evaporation of water. Plastic sheets inside the tower create a large surface area, ready for evaporation. Just like nuclear power plants, these cooling towers rely on natural airflow throughout the tower. To help the process, some towers utilize a motor to generate quicker and more efficient airflow.

How Are Cooling Tower Repairs Done?

If you have any questions regarding the operation of your cooling tower, now is the time to reach out to a professional repair service. Typically, most professionals services will go through these steps during any repair process:

  • Inspection: Professionals will always perform an extensive physical inspection of the tower.
  • Analysis: Utilizing advanced computer modeling, the company will enhance its capabilities of the tower and make any necessary repairs.
  • Engineering: Professionals services will use the latest industry technology to offer increased cooling capacity.

Repair Services

Here are some typical available services:

  • Structure refurbishment.
  • Wood to FRP conversion.
  • Counterflow to crossflow conversion.
  • Gear reducer conversion.

Cooling Tower Repair And Maintenance Tips

The following cooling tower maintenance tips are simple and can help you save up to 15% on the costs of electricity. As well as conserving water, a regular maintenance routine also extends the functional life of cooling equipment and ensure you get the maximum performance possible from your cooling towers.

Cooling Tower Maintenance Tips

  • Inspect the unit and having listened to it, take note of any noises that seem unusual to use as a baseline for any potential issues that may arise.
  • Follow the recommended and proper lock out procedures and disconnect motor switches before the commencement of any hands-on work. This is to ensure your safety.
  • Having made an inspection of the strainers cleaning debris from them will help to maintain excess materials from infiltrating the system.
  • Conduct an inspection of the water distribution system and check for dry areas over the fill coil section to increase system capacity by avoiding scale build up. If the surface is not fully wetted, check the nozzles for clogs and cracks.
  • Flush debris and dirt through the sump strainer or tower drain from the cold water basin to keep dirt from accumulating and to ensure maintenance of water filtration.
  • Find the appropriate predetermined water level by checking the makeup water supply. This will reduce air entrainment and conserves water.
  • As per the evaporation and local water quality regulations where you live, adjust the bleed rate to prevent the accumulation of solid mater in what that is being recirculated.
  • Optimal performance of the belt drive system is reliant upon any tension problems being properly addressed and fixed.
  • Always follow the manufacturers recommendations for assuring reliable service by routinely checking the oil quantity, oil level and shaft alignment for a gear drive system.
  • Every three months at a minimum, lubricate the bearings of fan shafts to ensure proper operation. You can eliminate the need for monthly bearing maintenance with the installation of bearing greasers that are automatic. This is an easy task to perform.

What Is A Closed Circuit Cooling Tower

Written by Brian B

What Is A Closed Circuit Cooling Tower?

Also known as evaporative fluid coolers, closed circuit cooling towers can keep your system cool and contaminant-free in a closed loop. Two separate fluid circuits are created within this model, resulting in spray water mixing with the outside air. Let’s take a look at closed circuit operation and configuration below.

Closed Circuit Cooling Tower Operation

These cooling towers operate similarly to open cooling towers. One of the only differences between the models is the heat load is transferred from the process fluid to ambient air through a heat exchange coil in closed circuit towers. The coil will isolate the process fluid from the outside air. This will keep it clean while in a closed loop.

Two separate fluid circuits are then created. They include an external circuit, which spray water circulates over the coil, eventually mixing with the outside air. The second is an internal circuit, in which process fluid circulates inside the coil. Heat is transferred from the internal circuit, processed through the coil to spray water, then to the atmosphere.

Combined Flow Configuration

Combined flow utilizes both a heat exchange coil and fill for a successful heat transfer. The fill addition will reduce evaporation in the coil section, which drastically reduces the potential for fouling and scaling. These closed circuit cooling towers use parallel flow of air and spray water over the coil, with crossflow water and air flowing through the fill.

Parallel flow means the water and air flow over the coil in the same direction. Process fluid will travel upwards to the top of the coil, which increases efficiency by bringing the coldest spray water in contact with the process fluid.

Counterflow Configuration

The flow of air goes in the opposite direction of the spray water in closed circuit towers. Air travels vertically through the unit while spray water goes downward over the coil. Process fluid then flows from top to bottom through the coil.

Induced Draft

Induced draft cooling towers are a type of mechanical draft tower that features one or more fans. These fans will be located atop the tower, drawing air upwards against the downward flow of water. The water is passed around the wooden packing or decking. In these models, the coolest water is found at the bottom, coming in contact with the driest air since the airflow is counter to the water flow.

With the warmest water found near the top of the tower in contact with moist air, this results in an incredibly efficient transfer of heat. Induced towers will either come in round or square shapes, distributing water via a sprinkler or static branch system. Incoming water is injected throughout the tower with a spray distribution header. The spray is directed downwards in order to maximize the contact of water and air. This process is maximized by the cooling water fill, which is made up of wood, metal, PVC or other materials. In general, induced draft models offer the most effective solution to the cooling needs of any industry.

Forced Draft

There are many benefits of using a forced draft cooling tower. And that is exactly why so many industrial plants opt for this model over the other options. Forced draft cooling towers are very powerful and affordable at the same time. These models will remove low-potential heat that is generated in the production process. A counterflow of air combined with hot water results in a transfer of heat in the cooling fill. Paper and chemical industry plants often prefer to used forced draft cooling towers.

Cooling Tower Cost 2022

Cooling towers generally cost around $125,000 to fully replace. A replacement will typically cost between $50,000 and $200,000 in the U.S. in 2022. A commercial cooling tower can last up 20 years. If you are searching online for “cooling tower cost“, this post will help!

Cooling Tower Costs

This article will go over the typical prices for the following products:

  • Feeder Water System
  • Blowdown System
  • Circulation Water System
  • Cooling Tower Refurbishing
  • Cooling Tower Installation

Feeder Water System

Costs can vary wildly when it comes to the feeder water system. Commercial customers can expect to pay anywhere from $50,000 to $250,000.

Blowdown System

A blowdown system needs nearly 75 percent of the water to be reused in a 100-gallon-per-minute stream. Typically, this system will cost around $300,000 total.

Circulation Water System

This side stream filtration unit can cost $50,000 for 100 GPM and a maximum of $300,000 for 1,000 GPM.

Cooling Tower Refurbishing

Cooling tower repair costs will certainly decrease when regular maintenance is performed. Regular maintenance will also increase the lifetime of the towers, hopefully heading towards a 20-year existence. Compared to a full repair, commercial companies generally pay 60 percent less for a refurbishing.

Cooling Tower Installation Cost

Whenever a cooling tower ages beyond 20 years, a rebuild is almost essential. The cost per ton of the replacement depends on the actual size of the cooling tower. Other features, such as epoxy treatment and equipment needed will affect cost, as well. Larger cooling towers will cost more and require increased maintenance attention.

Again, a complete cooling tower replacement will cost anywhere from $50,000 to $200,000.

Dry Cooling Tower Guide

Written by Brian B

Dry Cooling Tower Guide

What are dry cooling towers and how do they differ from other applications used today for cooling purposes?

What Is A Cooling Tower?

A cooling tower can be thought of as a specialized heat exchanger where water and air meet with the purpose of reducing the temperature of the water. When this happens, a small total of the water evaporates, hence reducing the water temperature that is circulated throughout the tower.

This water is pumped through pipes to the cooling tower. Nozzles are used as the water sprays onto material known as fill that slows the flow of the water as it travels through the cooling tower and maximizes air and water contact. When they meet, a cooling action is created and the cooled water is then pumped back to the processing equipment where it absorbs hear. From there it is pumped back to the cooling tower and obviously, cooled again.

Dry Cooling Towers Defined

A dry cooling tower is a closed-circuit tower, which operates by transferring excess heat from the system. These towers operate by heat transfer that occurs through a surface separating ambient air and working fluid(s). Either water or a mixture of water-glycol is the medium used within these towers. The principle of heat transfer takes place by heat exchanger with extended fins. Air can be introduced through natural or mechanical draft in order to move the air through air-cooled heat exchangers.

Unlike most other towers, dry towers do not use evaporation. As a result, the consumption of makeup water is minimal. Additionally, the fan in the system uses an electric motor to operate. The system overall functions with air cooling technology and the hot water circulation enables the heat exchange because the tubes are exposed to the ambient air flow surrounding them.

For an improved affect on performance, there is an increase in volumetric flow rate of air through the heat exchangers. Meanwhile, one of the downsides of this system is the lower efficiency, especially when the ambient air temperature is high. The tower has been designed with controlled expansion of both the tube and fin, which provides a smooth and clean tube for water pressure drops. The motors are specifically designed to keep the efficiency high with moisture, dust and rain-resistance.

Dry Cooling Towers Application

While there are different performance ranges for the dry cooling system, it is possible to choose the best one for your specific industry needs. Ranged from 5-2,000 kW performances, these systems have different noise levels and typically are destined for outdoor installation. Dry cooling towers can be used in the solar industry, factory cooling, power plant and plastic industry, among others.

Yes, you can use dry cooling towers in computer room air conditioning systems and water-cooled chilled water air condition systems, among others. In particular, this tower application works well in places where water resources are scarce. They can easily help eliminate excess heat without damaging the outside environment.

Regular maintenance is needed with dry cooling towers to make sure the system is operating as efficiently as possible. This regular maintenance will prevent future damage and avoid compressor failure. When the dry cooling system runs efficiently, energy consumption and costs will plummet.

Fluid Cooler Vs Cooling Tower

Which type of process fluid cooling system is right for your application? When determining whether you need a fluid cooler or a cooling tower, you must consider the desired temperature and operating costs, among other factors. The first step towards making a purchase is knowing the difference between these two models.

What Is A Cooling Tower?

A cooling tower can be thought of as a specialized heat exchanger where water and air meet with the purpose of reducing the temperature of the water. When this happens, a small total of the water evaporates, hence reducing the water temperature that is circulated throughout the tower.

This water is pumped through pipes to the cooling tower. Nozzles are used as the water sprays onto material known as fill that slows the flow of the water as it travels through the cooling tower and maximizes air and water contact. When they meet, a cooling action is created and the cooled water is then pumped back to the processing equipment where it absorbs hear. From there it is pumped back to the cooling tower and obviously, cooled again.

Cooling Tower Types

These cooling towers are used to cool several products and machinery. Despite the various uses and machinery associated with this product, all cooling towers operate in the same way. Evaporative cooling is utilized in all circumstances.

Crossflow Cooling Towers

Because of its design, crossflow cooling towers force the hot process water to flow down the fill media. This is caused simply by the force of gravity. This process takes place at the same time as the air is being blown horizontally across the falling water, which cools it down significantly. The air flow and pattern of the water is where the crossflow model gets its name. Water will require only gravity for downward flow because there is no other present force going against it. Water will then be evenly distributed by the hot water basins located above the fills in the tower.

Counterflow Cooling Towers

Hot process water flows downward on the fill media, continuing its flow all the way onto the cold water basin. The air, though, enters in a lower section of the tower, compared to crossflow versions. From there, air will flow up, passing through the water flowing the fill. The end result here will be a cooling down phase. Pressurized pipes and nozzles are placed further apart than in crossflow towers. This is done to ensure nothing will obstruct airflow to the tower.

Forced Draft Cooling Towers

There are many benefits of using a forced draft cooling tower. And that is exactly why so many industrial plants opt for this model over the other options. Forced draft cooling towers are very powerful, yet economical at the same time. These models will remove low-potential heat that is generated in the production process. A counterflow of air combined with hot water results in a transfer of heat in the cooling fill. Paper and chemical industry plants often prefer to used forced draft cooling towers.

Factory Assembled Cooling Towers

Simple and easy transportation, installation and operation are some of the biggest reasons why plants love factory assembled towers. These versions continue to be extremely popular because they are some of the few towers that can be customized to your specific needs. Generally, these towers are used for HVAC and industrial applications where cooling efficiency is not a priority and space is limited.

Induced Draft Cooling Towers

This version features a fan at the top of tower, pulling the air upward. Fans in induced draft cooling towers then induce the hot, moist air out of the discharge. A powerful exit air velocity reduces any possible recirculation within the tower as the end result. That is the main goal for these models: to eliminate the possibility of any discharged air flowing back into the air intake area.

What Is A Fluid Cooler?

Fluid cooler systems are more commonly used for applications featuring warmer temperatures. These systems consist of copper tubes with aluminum fins and fans, which act as a radiator used to cool the process fluid with ambient air. Typically, the coolest practical leaving fluid temperature is nearly 10 degrees warmer than the air entering these applications.

When compared to cooling towers, fluid cooler systems are not as energy efficient. In addition, these systems will come with a higher initial cost and have a larger footprint. However, once installed, fluid coolers have less maintenance needs and use less water than cooling towers. On average, operating costs of a fluid cooler will fall right between that of a chiller and cooling tower.

How Do Chillers And Cooling Towers Work
Regular Post
Written by Brian B

How Do Chillers And Cooling Towers Work?

Cooling towers operate as large-scale heat exchangers, often placed atop a building, blowing air across a coil to remove heat. A chiller, meanwhile, is a large piece of industrial equipment located inside a building. There are many different types of chillers, yet all chiller models will contain an evaporator and a condenser.

How Do Cooling Towers And Chillers Work Together?

Working together, chillers and cooling towers make it possible to air condition large areas. In the chilled water system, the evaporative cylinder creates the cold water used for air conditioning. The chilled water (usually 45 degrees Fahrenheit) travels upwards to the riser, where it branches off and into air handling units found on several floors within a building.

This system features water flowing through a coil inside the air handling unit, with indoor air blowing over it. The heat that is transferred from the air to the water will then leave cooler air to circulate throughout the building. The water is about 55 degrees F by the time it flows out of the coil.

Condensed Water System

The condenser cylinder is connected to the evaporator cylinder in this system. The connection keeps the heat moving out of the evaporator and into the condenser. Yet, these two water lines will never interact with one another. Condenser water is warm water that travels up to the riser at about 95 degrees F. From there, the water heads towards the cooling tower located on the roof.

Once in the cooling tower, the condensed water will flow through the tower while fans pull in ambient air used to transfer heat out of this water. The condenser water will then return to the condenser cylinder more than 20 degrees cooler than when it first entered the tower.

Chiller And Cooling Tower Sizes

Multiple cooling towers and chillers may be needed depending on the size and layout of the building. Many sites, for example, will include redundant systems to prevent a building from going out of service if one part breaks down or fails. This failsafe will also allow for maintenance and repairs to take place while the cooling system is in operation.

Cooling Tower And Chiller Differences

Within chillers, heat is removed directly from the coolant. The heat is then transferred to the surrounding air. This is an essential part of any cooling process. Cooling towers, meanwhile, remove heat from water that is discharged from a condenser. Any plant or factory that happens to choose a system that is not appropriate for the area will have trouble properly cooling their surroundings.

While chillers and cooling towers do produce similar results, the slight differences between the two systems are why they are used in different settings. Cooling towers are generally used in oil and gas refining plants, thermal power stations and power plants neighboring bodies of water. Chillers are found in plastic-industry applications, microbreweries and wineries.

Types Of Chiller

There are two main types of chillers used today:

  • Water-Cooled Chillers
  • Air-Cooled Chillers

Cooling Tower Types

There are many more versions of cooling towers than chillers. Here is a list of the common models on the market:

  • Crossflow Cooling Towers
  • Forced Draft Cooling Towers
  • Induced Draft Cooling Towers
  • Factory Assembled Cooling Towers
  • Counterflow Cooling Towers

Counterflow Vs Crossflow Cooling Tower

If you are searching for crossflow and counterflow cooling towers, we’re here to highlight the similarities and differences between the two models.

Crossflow Cooling Towers

Because of its design, crossflow cooling towers force the hot process water to flow down the fill media. This is caused simply by the force of gravity. This process takes place at the same time as the air is being blown horizontally across the falling water, which cools it down significantly.

The air flow and pattern of the water is where the crossflow model gets its name. Water will require only gravity for downward flow because there is no other present force going against it. Water will then be evenly distributed by the hot water basins located above the fills in the tower.

Crossflow Advantages

  • Excellent performance in cold-weather applications.
  • Capable of up to 70% turndown.
  • Water distribution system can be cleaned while machine is operating.
  • Utilizes high-efficiency heat transfer fill.

Counterflow Cooling Towers

Hot process water flows downward on the fill media, continuing its flow all the way onto the cold water basin. The air, though, enters in a lower section of the tower, compared to crossflow versions. From there, air will flow up, passing through the water flowing the fill.

The end result here will be a cooling down phase. Pressurized pipes and nozzles are placed further apart than in crossflow towers. This is done to ensure nothing will obstruct airflow to the tower.

Counterflow Advantages

  • Ease of installation.
  • Lower operating weight.
  • Can accommodate a wide range of fill types.

Cooling Tower Maintenance Requirements

Regardless of the cooling tower model, routine maintenance is essential to ensure optimal performance. Depending on the application, crossflow cooling towers could require less maintenance needs. This is due to the location and number of air inlets. Crossflow towers have two air inlets, while counterflow towers feature four air inlets.

Operating Weight

Due to the crossflow tower’s larger footprint, shipping and operating weight may be more than a counterflow model. Additional structures used for support do make maintenance/cleanings easy, though. More piping used in the water distribution system will only add to the overall weight of the crossflow towers.

Should You Choose A Crossflow Or Counterflow Cooling Tower?

Choosing which tower you should use between a crossflow and counterflow will very much depend on your specific industry needs. Both models are incredibly effective at supporting chillers and acheiving evaporative cooling with only slight differences in design.

What Is A Natural Draft Cooling Tower?
Regular Post
Written by Brian B

What Is A Natural Draft Cooling Tower?

Natural draft cooling towers operate on the stack effect, which causes hot air to rise within the tower.

Natural Draft Cooling Tower Features

Natural draft cooling towers are frequently used in power plants. The tower’s stack effect is responsible for producing the necessary air stream volume for cooling. These models offer a unique economic advantage in that the energy requirement is extremely low. This means, of course, that operating costs are minimal.

The large distance found between the air inlet and outlet avoids any recirculation of warm air, which could lead to a less efficient operation. The lack of moving parts make this model so reliable and inexpensive when infrequent maintenance needs occur.

Here are other advantages offered by natural draft towers:

  • High degree of reliability.
  • Low maintenance costs.
  • Low energy costs.
  • Efficient components.

Forced Draft And Induced Draft Cooling Towers

There are many benefits of using a forced draft cooling tower. And that is exactly why so many industrial plants opt for this model over the other options. Forced draft cooling towers are very powerful and affordable at the same time. These models will remove low-potential heat that is generated in the production process. A counterflow of air combined with hot water results in a transfer of heat in the cooling fill. Paper and chemical industry plants often prefer to used forced draft cooling towers.

So, how do forced draft models differ from induced draft towers? Induced draft versions feature a fan at the top of tower, pulling the air upward. Fans in induced draft cooling towers then induce the hot, moist air out of the discharge. A powerful exit air velocity reduces any possible recirculation within the tower as the end result. That is the main goal for these models: to eliminate the possibility of any discharged air flowing back into the air intake area.

Induced draft implies an inlet fan placed atop the tower, which creates low pressure. Forced draft, meanwhile, features an exhaust fan at the base of tower. This will then create the overpressure. Both centrifugal and axial fans can be used in forced draft models.

Induced Draft Features

  • Low-absorbed capacity.
  • Higher noise level than forced draft.
  • Humid air stream drive.
  • Requires little space for installation.

Forced Draft Features

  • Ease of maintenance.
  • Lower noise levels.
  • Dry air stream drive.
  • Low-absorbed capacity.
