How Does an Air Cooled Water Chiller Work?

An Air Cooled Water Chiller is a highly reliable cooling device that collects heat from the system by chilled water and dissipates it through air circulation.

This working process of the chiller is given below:

Step 1

Chilled water from the water tank circulates through the duct system in the required application or building for heat absorption.

Water coolant gets hot after heat absorption from the system and enters into evaporator/heat exchanger.

Step 2

The heat exchanger consists of a tubing system in which the chilled refrigerant circulates. The hot water circulated over the refrigerant. The heat is transferred from coolant to refrigerant.

After heat absorption, the liquid refrigerant evaporates. The gaseous refrigerant with low pressure leaves the evaporator and enters the compressor.

Step 3

The scroll/screw compressor of the Air Cooled Water Chiller receives the low pressured refrigerant and mediates compression force over the refrigerant.

Refrigerant with high pressure and temperature leaves the compressor and enters into the condenser.

Step 4

The air-cooled condenser receives the coming refrigerant and dissipates heat by air circulating over condenser coils.

The air is released into the environment and the refrigerant condenses into a liquid state.

Step 5

After condensation, the refrigerant enters into an expansion device that lowers the pressure and temperature on the refrigerant.

Step 6

The refrigerant then enters again into the evaporator to repeat the refrigeration cycle.

What is the Refrigeration Cycle of Air Cooled Water Chiller?

The refrigeration cycle of an Air Cooled Water Chiller consists of a compressor, air-cooled condenser, evaporator, and expansion valve through which the refrigerant circulates.

Two processes take place in the refrigeration cycle:

1 Evaporation Process

The liquid refrigerant changes from the liquid phase to the gaseous phase inside the evaporator after heat absorption comes from the system.

2 Condensation Process

The gaseous refrigerant condenses back into a liquid state in an air-cooled condenser after heat discharging in the outside environment.

Refrigeration Cycle

In Air Cooled Water Chiller, the heated water coming from buildings or processing applications gets enter inside the evaporator.
The chilled refrigerant of the evaporator again cools down the water to circulate back in buildings. The gaseous refrigerant moves towards the compressor.
The compressor puts compression force over the refrigerant. The pressurized refrigerant discharged from the compressor enters the air-cooled condenser for the final heat dissipation.
After that refrigerant enters again in the evaporator to start up the next cycle. This is called the refrigeration cycle.

What are the Basic Configurations of an Air Cooled Water Chiller?

An Air Cooled Water Chiller is available with different configurations. Different configurations depend upon the application requirements as well as environmental conditions.

The basic configuration is given below:

Single Piece/Packaged Chiller Unit

The single packaged unit consists of all of its refrigeration components together in a single unit for easy installation and maintenance.

The main advantage of Packaged Air Cooled Water Chiller is that it is factory mounted. All validation tests are performed in a factory with refrigeration pipe assembly and power connections etc.

It can be installed outdoors under controlled environmental conditions.

Split System for Air Cooled Water Chiller

Alternatively to the packaged unit, a split system configuration is also adopted for chiller designing.

In the split system, all of the refrigeration components are not configured inside a single unit but instead, the compressor and condenser are installed outdoors.

While the evaporators/heat exchanger component of the refrigeration system is placed indoors.

Both indoor and outdoor components of Air Cooled Water are connected by refrigeration piping.

Its primary advantage is that during winter when the ambient temperature reaches to lower level, the evaporator indoor installation prevents the refrigerant from freezing.

Condenserless Chiller

The Air Cooled Water Chiller configuration consists of all refrigeration components together except for the condenser unit that is placed outdoor while compressor, evaporator, and control units are placed indoors.

The advantage to use this type of configuration is easy installation, maintenance, and troubleshooting in case of any extremity in weather.

Which Types of Compressors are Featured With Air Cooled Water Chiller?

Three types of compressors can be integrated with Air Cooled Water Chiller as given below:

Scroll Compressor

Scroll compressors are highly efficient as compared to the reciprocating compressor because it contains 60% moveable components.

The compression ability of the scroll compressor is highly reliable as it contains one fixed scroll unit and the other is a moveable/ rotary unit.

When rotary scroll moves coupled with fixed scroll, pressure is exerted over circulating gas. In the end, gas is discharged from the scroll compressor with high pressure.

These compressors are available hermetically with up to 25 Ton capacity. More than one compressor can also be integrated to increase capacity.

Screw Compressor

Screw compressors are commonly used for Air Cooled Water Chiller. One or more than one screw compressor is attached to meet needs ranges 70 Ton to 500 Ton.

It consists of more than one rotor for gas compression. A screw compressor is also considered better as compared to a reciprocating compressor because of its rotary parts.

It can compress the fixed amount of refrigerant entering because of its positive displacement feature.

Reciprocating Compressor

Reciprocating compressors are mediated to receive a fixed amount of refrigerant for compression under its positive displacement featuring.

It consists of rods, intake valves as well as discharge valve and piston.

The valves act to control the suction pressure as well as discharge pressure. It is also available in hermetic or semi-hermetic and can be configured with a single compact unit.

Which Type of Condenser is Used for Air Cooled Water Chiller?

Air Cooled Condenser

For Air Cooled Water Chiller, the air-cooled condensers are used for system heat dissipation.

Air-cooled condensers consist of circulating coils in which the refrigerant enters coming from the compressor.

The condenser is featured with a cooler that is air circulating over condenser coils. All of the heat from the hot refrigerant is transferred to the condenser.

The continuous air is drawn over the condenser by impeller fans.

The condenser coils of air-cooled condensers are designed differently to protect them from corrosion effects as:

The condenser has copper coils and aluminum fins or the entire unit is designed with copper that ensures condenser protection from corrosion effects.

Finally, the condenser lowers the temperature of the refrigerant and converts it again into a liquid state.

Which Type of Heat Exchangers is Configured With Air Cooled Water Chiller?

Three different types of heat exchangers are integrated with Air Cooled Water Chiller assuring the availability of a various number of chiller designs as given below:

Flooded Shell and Tube Type Heat Exchanger

This type of evaporator/heat exchanger consists of tubing covered with a shell. The tubing always entailed water flooding.

While the refrigerant present in shell flowing over water coolant coming from processing unit.

It is a less efficient heat exchanger. When it is installed for Air Cooled Water Chiller, the number of tubing is increased to level up the chiller working efficiency.

The chiller containing a centrifugal compressor is featured with this flooded type heat exchanger.

Expanded Shell and Tube Type Heat Exchanger

This type of heat exchanger also contains tubes and a shell as its basic components. The refrigerant flows inside tubes of the heat exchanger, while the water coolants flow over tubes, present in the shell.

After heat transfer from hot water, the refrigerant gets evaporated and moves out from the heat exchanger at low temperature and pressure.

Air Cooled Water Chiller containing reciprocating compressor or scroll compressor is preferred to integrate with direct expansion shell and tube type heat exchanger.

Brazed Plate Heat Exchanger

This type of heat exchanger is efficient in its working as compared to other types of heat exchangers.

It consists of multiple plate facings to which the tubing is attached. The fluid flows inside tubes. One tube contains refrigerant. While the other tube contains water circulation.

On one side hot water and chilled refrigerant enter inside tubes. While on the outlet evaporated refrigerant and chilled water flows out.

The efficiency of the brazed plate heat exchanger increased under a small cross-sectional area of plates and fluted design that increase the turbulence in the fluid.

It also occupies lower space in Air Cooled Water Chiller ensuring turbulence in fluid for part-load applications.

How is an Air Cooled Water Chiller Different from Water Cooled Water Chiller?

Air Cooled Water Chiller and water cooled water chiller differ from each other based on their refrigerant cooling process as soon as it comes out from compressors as:

Air Cooled Water Chiller

This type of chiller is featured with air-cooled condensers for the cooling of refrigerants. Condenser coils are surrounded by ambient air as a condenser medium for heat dissipation.

While condenser fans mediate the air circulation over coils. The condenser capacity depends on airflow rate, refrigerant temperature, and surface area.

Water Cooled Water Chiller

A water cooled water chiller contains water-cooled condensers to cool the refrigerant.

The water employ over condenser coils as condenser medium. Pumps assist water circulation over coils. As the refrigerant passes from copper coils heat is transferred to water circulation.

In this way, heat discharges from the refrigerant. While heated water moves back to the cooling tank for getting cooling back to the recycling process.

How is Stationary Air Cooled Water Chiller Different from Portable Air Cooled Water Chiller?

Stationary Air Cooled Water Chiller

A specific type of chiller that does not have a water pump and tank integrated inside the unit.

The tank is connected to the chiller with separate piping is called a stationary Air Cooled Water Chiller.

This type of chiller has separate electrical connections as well as a control system.

Portable Air Cooled Water Chiller

A precise type of chiller containing all of its basic components together and can easily be moved from one position to another is called Portable Air Cooled Water Chiller.

Compressor, pump, evaporator, and condenser are integrated for overall operation. Electrical connections and control system is configured with the unit for controlling overall function.

Stationary Air Cooled Water Chiller

Which Refrigerant is Installed in an Air Cooled Water Chiller?

R-410A and R-407C refrigerant is installed in the Air Cooled Water Chiller as it is environment-friendly and efficient refrigerant for heat transfer.

R-22 refrigerant is also used in some models. But now its usage has been stopped as it contains chlorine that is hazardous for the environment.

The chlorine radicles effects on ozone layer causing global warming. Therefore R-410A and R-407C refrigerants are widely used as compared to R-22.

What are Capacity Control Methods of Air Cooled Water Chiller?

The Air Cooled Water Chiller is configured to work at full capacity based on application load. So its capacity can be controlled by the following methods:

Compressor Unloading

The capacity can be controlled by unloading the compressor. The scroll compressor has not the capability to be unloaded.

The screw compressor and reciprocating compressor undergo this process. The suction valves of the reciprocating compressor are opened by the unloader resulting in a reduction of compression over the refrigerant.

While the side valves of the screw compressor cover the suction valves reducing screws length as well as compression over the refrigerant.

In this way, the capacity of the compressor is being controlled.

Cycling of Compressor

When multiple compressors are organized within the chiller, the cycling compressor method is commonly chosen.

It is an energy-efficient and highly reliable capacity controlling method. But one drawback is that by its continuous use, the motor of the compressor can be damaged.

In multiple compressors, when the load will be at peak, the refrigeration cycle will run in all integrated compressors.

But if there is a lighter load, the individual compressors are cycled-off to reduce the load or capacity.

Hot Gas Bypass

This method is also suitable for capacity control. The highly pressurized refrigerant that discharges from the compressor should be entered into a condenser for heat discharge. But the refrigerant is reversed back towards the evaporator.

In this way, some of the refrigerants lose while moving back towards the compressor and capacity reduces at hot gas bypass.

But it is not considered a reliable method because of the continuous operation requisite for the compressor to complete the refrigeration cycle.

How to Troubleshoot your Air Cooled Water Chiller?

An Air Cooled Water Chiller can face some problems while operation that can be troubleshot as explained below:

If the compressor is not working, the refrigerant charge can be below. To troubleshoot the problem check out the refrigerant charge and refill it.
In case the water flow rate is slow down then inspect the water pump and clean it to sort out the problem.
If motor windings are not cooled properly then measure superheating of heat exchanger and adjust it if needed.
Check if the compressor is taking the time or turning on with difficulty, any mechanical problem or faulty windings can occur. This problem can be troubleshot by replacing the compressor.
The compressor is making vibrations and noise, the fault can be by blockage of expansion valve or rupturing of suction valve. The problem can be troubleshot by replacing valves with a new one.
Abnormally heating of condenser can be due to the high refrigerant charge. This is sorted out by recovering the refrigerant charge.
If water is too cold at the condenser, the problem can be due to tube fouling. Clean the tubes for the sorting problem.
