Let’s know more about it.

What is a Packaged Air Cooled Chiller?

A Packaged Air Cooled Chiller is a air cooled water cooling system that utilizes the ambient air to help in chilling the liquids or water. It works in coordination with an air handling unit.

The fan, the coils, and the motor, all parts of the Packaged Air Cooled Chiller are integrated into one assembly which makes it very convenient and preferable to use.

It uses a refrigeration cycle to make a fluid heat-free thus cooling it down.

This cooled fluid is then used for HVAC and Air Conditioning purposes for different applications depending on the load.

Because of its mobility and energy-saving advantage, it is extensively used in commercial units, large setups, and industrial units as well.

What Are the Main Parts of a Packaged Air Cooled Chiller?

Following are the major parts of a Packaged Air Cooled Chiller

  • Compressor

It is the powerhouse for your Packaged Air Cooled Chiller. It provides the energy and force to the cooling agent in the device. Stated below are the four types of compressors.

  • Screw
  • Scroll
  • Reciprocating
  • Centrifugal
  • Condenser

It is an array of some parallel hoses or tubes. Within these pipes, the hot refrigerant moves along.

To reduce the surplus heat energy, some fresh air passes through the condenser.

  • Condenser Fans

These condenser fans play a pivotal role in distinguishing between the water cooled and Packaged Air Cooled Chiller.

They help in moving the air through the condenser so that the air is spread evenly.

Thus removing the unnecessary heat energy from the set- up.

  • Expansion Valve

It is a valve that plays its role within the expansion of the fluid as it is converted from its typical liquid form to the gaseous form.

Later on, the refrigerant is entered into the evaporator.

  • Evaporator/Heat Exchanger

Water is chilled in the evaporator when unwanted heat is drawn into the refrigerant before it is fed into the condenser.

  • Filter Drier

The system during its working process produces some undesired impurities that must be removed.

For this purpose, the Packaged Air Cooled Chiller system has a filter drier. However, this drier gets blocked by the contaminants if not taken care of.

Therefore, it is required to change the filter drier on a regular basis.

What Are the Features of a Packaged Air Cooled Chiller?

Here are a few prominent features of a Packaged Air Cooled Chiller.

  • It is authentic and economical.
  • A Packaged Air Cooled Chiller is Eco friendly.
  • It has a high precision level.
  • Due to its excellent efficiency there is no compromise in the best quality function of its system even under extreme outer conditions.
  • The specifically designed condenser fans help in better air and heat regulation.
  • As it uses ambient air for its function, it requires minimum maintenance and minimum expenditure.

How Does a Packaged Air Cooled Chiller Work?

A Packaged Air Cooled Chiller uses the principle where the vapors are compressed. The basic idea is to absorb the heat energy from the prepared water.

The following mentioned steps will help you to have a better understanding of the working of Packaged Air Cooled Chiller.

  • The refrigerant is used to dissipate the heat and once it is done, it becomes warm. So it is once again sent to the Packaged Air Cooled Chiller.
  • The heat in the warm water is evacuated from the water with the help of the evaporator that is mentioned above.
  • As the water moves along the tube of the evaporator, its form is changed. Thus, it gets converted into a gas with low pressure.
  • The low-pressure gas is then moved to a compressor. In the compressor, the gas is modified or compressed to high-pressure gas.
  • This high-pressure gas is then moved towards the condenser. Here, the heat energy is dissipated as it is released into the surrounding atmosphere with the help of condenser fans.
  • As the system releases the heat outside, there is a high chance that the area becomes heated. To avoid this problem make sure to place the Packaged Air Cooled Chiller in a spacious area.
  • Now that the heat has left the system, the modified refrigerant is converted back into the liquid form having a high pressure.
  • This high-pressure liquid then moves towards the evaporator via the expansion valve. Here, the refrigerant is modified again to get converted into low-pressure liquid.
  • As you know, the Packaged Air Cooled Chiller works continuously, the liquid is moved back into the evaporator. Thus the cycle is repeated.

What is the Difference Between Water Cooled Chiller and a Packaged Air Cooled Chiller ?

The main difference between the water cooled chiller and the Packaged Air Cooled Chiller is based on the ejection method of the unneeded heat from the system.

  • Water is pumped via a condenser in a water cooled chiller and then it is spread with the help of a cooling tower.
  • On the contrary, no cooling tower is involved in a Packaged Air Cooled Chiller system and the air is dispersed with the help of condenser fans as told above.
  • The water cooled chiller uses a flow of moist or humid air while the Packaged Air Cooled Chiller uses a flow of ambient air.
  • The cooling tower in the water cooled chiller requires a massive space while the condenser fans in the Packaged Air Cooled Chiller do not need much space.
  • The maintenance of water cooled chiller is quite costly as they have large towers while the Packaged Air Cooled Chiller has low maintenance costs.

Is a Packaged Air Cooled Chiller Better Than a Water Cooled Chiller?

The following points will help you consider why you must choose a Packaged Air Cooled Chiller: 

  • No need for spacious and expensive cooling towers
  • Low maintenance costs, thus quite pocket-friendly.
  • In the water-scarce areas, the Packaged Air Cooled Chiller is the best
  • As it only involves air and water, thus any chemical cost is saved.
  • As it requires a humble quantity of water, thus water expenses are saved.
  • If a crisis results in a water shortage, you do not have to worry about your Packaged Air Cooled Chiller.
  • It is very environmentally friendly and so you don’t have to worry about the wastage of water.
  • It is quite easy to operate and control.

Thoroughly check and inspect all the wires and their connections. Examine your motors to find any insulation-related issues.

How to Increase the Working Efficiency Of your Packaged Air Cooled Chiller?

If the Packaged Air Cooled Chiller is working and running a load of about 70-75 percent, then the efficiency is at its maximum level.

1) Variable Frequency Drives

If you want to decrease the operating expenses and boost up the efficiency level, then invest in installing a Variable Frequency Drive.

This VFD will help in reduced fluctuations of the compressor thus preventing the recurrent starting and stopping of the compressor.

It helps the Packaged Air Cooled Chiller system to work more efficiently.

2) Draining your Refrigerant Oil and Changing the Filters

It is very important to drain out the refrigerant oil when needed. If it is not done on time, then it could be hazardous.

If the oil is not drained, when it must be, then the transfer of heat is improper and temperature is also affected and the system is forced to overwork to provide maximum efficiency.

However, to perform this whole process safely and efficiently, some professionals must be hired. The best way to drain out the oil is from the oil pot.

It must never be drained out from the system directly.

3) Energy Audit

To improve and maximize the efficiency level, you must look into the energy audit of the Packaged Air Cooled Chiller.

This will help you in providing some ultimate suggestions and thus aid in lowering the use of energy.

The audit also compares the level of energy of your system to some honed and perfect system.

4) Maintenance Tasks 

You should maintain your system regularly so that it works efficiently. Some of them must be done on a regular basis while others can be done per annum.

Annual Maintenance Tasks

  • Testing the safety controls.
  • Examine the pressure valves to find if there is any build-up.
  • Inspect vent lines. Make sure they are clean.
  • Checking the electrical connections.
  • Inspect the calibration of the pressure scales.

5) Rebuilding the Compressor

The compressor is a very vital component of the Packaged Air Cooled Chiller.

Although, the compressors are supposed to work without any break, however, if they are used for a very prolonged time duration then they can get worn out.

This can cause problems of all types. In order to increase the life span of your compressor, you must keep doing the regular maintenance of your device.

If the compressor is having some unwanted problems, and its machinery deteriorates, then you need to replace it.
