We all face the problem of excessive heat production as a result of various industrial processes. To solve the overheating issue, An Air Cooled Water Chiller is a great cooling device can release boring heat.

An Air Cooled Water Chiller is a refrigeration machine that uses air to lower down the temperature of the increased heat that is produced from various industrial machines.

Whether you want to use it in the plastic, foam, or the chemicals industry, it will be efficient in removing the heat.

But before getting an Air Cooled Water Chiller for your application, it is essential to understand its construction and working.

Moreover, some tips for Air Cooled Water Chiller maintenance, cooling efficiency, and safety will help you know more. So, let’s get started.

What is an Air Cooled Water Chiller?

An Air Cooled Water Chiller is a water cooling device that is used to get rid of excessive heat.

Air Cooled Water Chiller is mostly used in small to medium-sized installations, although recent improvements in its construction have enabled it to be used in large installations as well, in the form of modular of it.

If you want an effective solution to the excess heat produced from machinery in the plastic, electroplating, chemicals, rubber, or any other one, you can surely use the Air Cooled Water Chiller.

The compressor, condenser, condenser fans, expansion valve, and evaporator collectively use air to get rid of extra heat. The condenser of an Air Cooled Water Chiller is cooled by the air temperature.

But always keep in mind to deeply clean your Air Cooled Water Chiller before and after use.

When there isn’t enough water or the water is very pricey, an Air Cooled Water Chiller is preferred.

What are the Major Parts of an Air Cooled Water Chiller?

The Air Cooled Water Chiller has 5 main parts.

  • The compressor, which is normally a screw, scroll, or reciprocating compressor.
  • The condenser is a bundle of horizontal tubes that holds the hot refrigerant and is surrounded on the vertical axis by a variety of thin metal sheets.

This aids in the transfer of heat from the tubes to the air that is blown through the tubes and thin metal sheets.

  • Condenser fans – These suckers draw air through the condenser coils from the sides and push it upwards across the top of the device towards the atmospheric air.
  • Expansion valve – Before the refrigerant reaches the evaporator, this valve opens it.
  • The cooled water is created in the evaporator, and the heat from the warm return “chilled water” is removed and sent to the condenser.

What are the Main Features of the Air Cooled Water Chiller?

  • Air Cooled Water Chiller is built and produced especially for plastic film blowing machines.
  • It is not noisy and works efficiently.
  • Temperature regulation of it is accurate, varying from 0 to 0.5 degrees Celsius.
  • It is strong and sturdy making it durable and long-lasting.
  • Air Cooled Water Chiller boosts the film’s thickness uniformity, clarity, and brightness significantly.
  • It has efficient cooling and dehumidification capabilities.
  • It increases the production of plastic film blowing machines by at least 20% to 30%.

How Does an Air Cooled Water Chiller Work?

Air Cooled Water Chiller actively collects heat from process water and then passes it to the air around the device.

This form of device is usually used in areas where increased heat discharge is not an issue, but rather an advantage. For example, the extra heat may be used to steam a room for less money than conventional heating systems during the winter.

The evaporator, which has a liquid refrigerant that runs over the evaporator tube package and evaporates, starts the loop. The chilled water flowing through the package absorbs heat throughout the process.

The refrigerant vapor is then pulled from the evaporator by the compressor. After that, the compressor is in charge of pumping the refrigerant vapor to the condenser, which boosts the temperature and pressure.

When refrigerant is in the condenser tubing, it condenses and releases its internal heat to the air or cooling water.

After that, the high-pressure liquid flows into the expansion system and through the evaporator, where the refrigerant pressure and temperature are also decreased.

The refrigerant returns to the cooling water coils and consumes more heat to complete the continuous cycle.

What is the Difference between Air Cooled Water Chiller and Water Cooled Chiller?

Water Cooled Chiller

Since Water Cooled Chiller has a cooling tower, it is more efficient than Air Cooled Water Chiller systems.

Since it condenses based on the ambient temperature bulb temperature, which is lower than the ambient dry bulb temperature, the Water Cooled Chiller is more effective.

The lower the condensing temperature of it, the more effective it is. The following are some of the most critical elements of this system:

  • Cooling towers
  • Condenser water taps
  • Make-up water tank
  • TES tanks

Air Cooled Water Chiller

The Air Cooled Water Chiller can be used in circumstances where functionality, environmental conditions, or water access are limited.

An air stream is used to transfer heat in both Air Cooled Water Chiller and Water Cooled Chiller.

The Water Cooled Chiller requires a cooling tower and operates using a humid air stream while the Air Cooled Water Chiller doesn’t require the cooling tower and operates using the ambient air current.

Water Cooled Chiller is typically less expensive and more effective, but they use a lot of water.

It has worked out how to blend advanced manufacturing practices with cutting-edge technologies to manufacture a highly competitive and reliable Air Cooled Water Chiller.

In terms of footprint, performance, and noise, the Air Cooled Water Chiller is very impressive.

The efficiency of these devices two decades ago, and also the steady rise in the NPLV rating of Air Cooled Water Chiller over time is remarkable.

The Air Cooled Water Chiller is extremely dependable when used in part-load applications.

What are the Uses of an Air Cooled Water Chiller?

  • It is used plastic manufacturing industry.
  • It also works in electroplating.
  • The automobile industry also makes use of Air Cooled Water Chiller
  • The use of Air Cooled Water Chiller is also signified in polyurethane.
  • Vacuum coating is done with help of it.
  • The chemical industry utilizes it in its functioning.
  • Hydraulic industry signifies its use as well.

How can you choose a Suitable Air Cooled Water Chiller for your Application?

Step 1: Determine the Heat Load

It is vital to find out how much heat the submission produces so that the Air Cooled Water Chiller you select is big enough for the task.

There are many methods for estimating the heat load (in BTU), but understanding the procedure is critical for precise heat load calculations.

Step 2: Choose the Type of Coolant, the Flow Rate, and the Temperature

The next step is to decide the coolant, its target temperature, and the flow rate that it would give to the process until the heat load has been determined.

The mechanism by which heat is transmitted from the process to the coolant, as well as the form of coolant used, dictates this. Water, for example, has different properties than oil.

Step 3: Identify Installation Environment

In what kind of condition would the Air Cooled Water Chiller be fitted? Indoor systems, for example, may be exposed to elevated temperatures and polluted conditions.

While outdoor structures may be subjected to both low and high ambient temperatures. This may affect its sizing and necessitate the use of accessories like air filters and sump heaters.

Step 4: Use Chiller Performance Curves

Now, based on the chilled water source temperature and the highest estimated ambient air temperature, use the output curves to pick an Air Cooled Water Chiller model that matches or exceeds the needed power.

To optimize the value of its range, the application’s protection margin should be considered in relation to usable frame sizes.

Step 5: Check Pump performance Curves

Test the pump output curves to make sure the pump can provide enough pressure at the specification flow rate to meet the application’s requirements.

Tiny coolant flow paths or longer lengths in some liquid-cooled systems will lead to higher pressure drops.

Step 6: Final Selection

Eventually, make sure the chosen Air Cooled Water Chiller meets the remaining submission criteria, such as power characteristics, control choices, footprint, organization listing, color, and so on.

Choosing a traditional device would provide you with better reliability, faster operation, and global assistance.

What are the Advantages of Using an Air Cooled Water Chiller for your Applications?

  • Cooling towers are not needed.
  • Lower operating costs
  • Easier to operate and monitor (no tower freezing or bypass)
  • Better environmental stability (no water waste)
  • Chemical costs are avoided
  • Water costs, especially in cities, are avoided
  • There are no water issues to cope up with.

How to Increase the Working Efficiency of your Air Cooled Water Chiller?

Examples of energy quality management methods that should be used for increasing the efficiency of the Air Cooled Water Chiller are mentioned below.

  • Reset the chilled water temperature set point. This technique clashes with the variable speed chilled water pumping strategy because it’s safer for constant flow systems.

For variable primary flow systems, the variable speed pumping should take priority, and then the chilled water temperature setpoint reset should take place until the flow is at a minimum.

  • Reset the condenser water temperature set point.
  • Market restricting
  • Effective initiate

What is the Procedure for Installing an Air Cooled Water Chiller?

  • Unpack and unload the Air Cooled Water Chiller System you just bought.
  • Before using the Air Cooled Water Chiller Device, read the protection and guidance book that came with it.

  • Use auxiliary ventilation equipment if necessary to remove the refrigerant vapor generated by an accidental leak.
  • Mount an air detector to monitor the refrigerant vapor content in the air, if appropriate. Please closely read the protection directions to ensure that all of the specifications are fulfilled.
  • Please hold the manual in a safe place for potential use. Make sure the controller is fully grounded and test it on a daily basis.
  • Inappropriate grounding will cause a sudden electric shock. Ensure that the solid and poor electricity are piped separately.
  • Ensure that the wiring follows the wiring instructions as described n the manual that comes with your Air Cooled Water Chiller.
  • Make sure that the voltage input of the isolating transformer is AC380V 10%, 50Hz.
  • Do not press the touchable screen with sharp objects, and do not press the screen too hard.
  • The power supply cords and contact wires should not be pulled or distorted.
  • To clean the dirty on the unit, do not use acid or alkaline material.
  • Wipe the device with a warm cloth dampened with clean water.
  • If a fire occurs, automatically turn off the control and use a fire extinguisher developed especially for oil and electric fires; it is not permitted to use the system in an explosive environment
  • Trained technicians should manage each part.
  • In the case of a leak or failure, please contact qualified repair technicians.
  • After each repair, the protection devices should be tested.
  • When a leak has been detected, all of the refrigerant in the device can be drained out, the leak point restored, and the unit charged with the necessary refrigerant according to the nameplate.
  • Any sections of the device can be isolated, and if a leak happens in these parts, the whole device does not need to be pumped out.
  • Until charging, make sure the refrigerant form fits the nameplate; charging the wrong refrigerant will result in severe damage.
  • When charging the lubricant in repair, make sure the lubricant form matches the technical document criteria.
  • To stop a violent reaction between oxygen and gasoline, do not vent oxygen into the device.
  • Don’t go over the limit. When the machine is turned on, the maximum operating pressure is allowed.
  • Only refrigerant or dry nitrogen can be used to search for leaks; oxygen is not permitted.
  • If the device contains no gas or liquid refrigerant, do not use burns or electrical soldering to sever any component or pipes.
  • When refrigerant comes into contact with a naked flame, toxic gas is generated, so protection should be given in the form of a readily available extinguisher.
  • To prevent refrigerant splashing on the skin or eyes, use a protective glass.
  • Please rinse the refrigerant from your face with soap and water, and if the refrigerant somehow splashes into your eyes, quickly wash your eyes with water and go to the hospital.
  • If you use a naked flame or steam to heat a refrigerant-containing pipe, you’ll end up with dangerously high pressure.
  • If a heating refrigerant is used, only mild temperature water can be used.
  • When the Air Cooled Water Chiller is running or there is internal friction, do not cut any covers or connections.

  • Please replace it as soon as possible.

 What are Some Maintenance Tips for your Air Cooled Water Chiller?

  1. Maintain your Daily Logs

As easy as it might seem, maintaining a daily log of operating conditions, including pressure and temperature in the Air Cooled Water Chiller, as well as fluid levels and flow rate, will help predict the probability of potential machine injury of it.

Keeping an Air Cooled Water Chiller log sheet is beneficial because it allows for the development of a preventative repair schedule before device real losses occur.

  1. Keep the Air Cooled Water Chiller Tubing Clean

Heat transfer is used in the industrial device operating theory to provide cooling.

An interruption in the flow of cooling fluid into condenser tubes can greatly reduce the efficiency with which an Air Cooled Water Chiller transfers heat in shell and tube and brazed plate heat exchangers.

Corrosion can build up within tubing of it over time, preventing the heat from being removed.

  1. Reduce the Temperature of the Condenser Water

Reducing the temperature of the water entering the condenser of an industrial chiller increases performance by requiring the Air Cooled Water Chiller to function less to provide overall cooling.

  1. Inspect the Condenser Water Loops

While all of the Air Cooled Water Chiller, cold shot chillers make are closed-loop, some of its condensers have water loops that use open cooling outlets like air-cooling towers.

As a result of the proximity to the environment, the water is more likely to become polluted with biological growths, degradation, and scale, which may decrease total heat transfer and its quality.

Chilled water loops should be tested and handled for toxins at least once a year. Inspect the chiller’s “Y” strainer on a daily basis, and use an inline cartridge filter for added safety.

For soil or airborne particle build-up, the light should be visible through the condenser coil. With a torch, look deep into the coils and clean as needed if they’re dusty.

  1. Monitor for Refrigerant Leaks

The amount of refrigerant circulating through the compressor of the Air Cooled Water Chiller determines how quickly it cools. Valve stems can become loose over time, causing refrigerant leaks.

The cooling capability of it may also be affected by refrigerant leakage from the compressor or the injection of moisture into the system.

What are the Most Common Problems Faced While Using the Air Cooled Water Chiller?

  1. Suction Pressure of Air Cooled Water Chiller is Too High
  2. Excess refrigerant: Excess refrigerant should be withdrawn following the standard.
  3. A significant volume of liquid refrigerant flows through the compressor while it is fully loaded: inspect and change the expansion valve and its temperature sensing kit.
  4. If a considerable volume of liquid refrigerant reaches the compressor, double-check the expansion valve and temperature sensing kit.
  1. The Suction Pressure of the Air Cooled Water Chilleris Too Low
  2. The condenser’s refrigerant liquid outlet valve is not completely open: it should be fully open.
  3. Clogged refrigerant pump: clean or install the filter on a daily basis.
  4. Expansion valve malfunction or improper modification: accurate adjustment or troubleshooting is needed, and repair is required.
  5. Insufficient refrigerant filling: it should be raised to the specified level.
  6. Unnecessary lubricating oil circulates in the water chiller’s refrigeration system: the source should be identified and the volume reduced to the required level.
  7. The evaporator’s inlet water temperature is too low: raise the water inlet temperature fixed value.
  8. Inadequate water by evaporator; check pump and water valve.
  1. The Compressor of the Air Cooled Water ChillerCannot Operate
  2. Overload safety or control line fuse blown: determine the trigger and, if necessary, repair the fuse.
  3. Control circuit communication failure: conduct frequent and prompt repairs to prevent more severe injuries.
  4. The compressor relay coil has burned out and needs to be replaced as soon as possible.
  5. Phase error: it must be corrected in a timely manner.
  1. Mechanical High-Pressure Switch

At least one high-pressure switch is installed in each circuit to keep the relief safety valve from opening.

If the discharge pressure increases too high, the Mechanical High-Pressure switch opens, cutting power to the auxiliary relay and halting the compressor.

As soon as the discharge pressure returns to normal, the alarm can be turned off. The warning on both the switch and the Unit Controller must be reset. The meaning of the initiating pressure cannot be changed.

  1. Relief Safety Valve for High Circuit Pressure

As the pressure in the refrigerant circuit rises too high, the relief valve opens to limit the maximum pressure.

If this occurs, turn off the computer automatically and call the nearest support agency.

What is the Trial Run Operation Procedure for an Air Cooled Water Chiller?

  • Connect the refrigeration gauge to the device and position the temperature probe, then switch on one of the compressors. Examine if the Y-delt transform of the compressor is natural, as well as the voltage of each contactor.
  • Check the current of the compressor.
  • Check that each fan’s rotation orientation is correct and that it is working normally, then look at the running current.
  • Check the oil level to make sure the power-changing solenoid valve is operating properly.
  • Allow at least 20 minutes for the compressor to operate before checking all parameters and ensuring that the suction and discharge pressures are natural.
  • Examine the opening of the electrical expansion valve in relation to the suction temperature and determine if it is within normal limits.
  • Check that the suction superheats temperature is between 5 and 7 degrees Celsius, and that the discharge and condensation superheat temperatures are within normal limits.
  • If the discharge temperature is too high, verify that the solenoid valve and expansion valve on the injection pipe is operating properly.
  • Check the compressor oil level after shutting down the unit.
  • An adequate amount of air conditioning load is needed to maintain the unit operating and to ensure that all air conditioning equipment is switched on.
  • Test and tighten all valve bonnets after the trial run. Clean the machine as well as some oil dirt in the joints.
