  • Those looking for a machine that can be used indoors can choose it.
  • Since it has a cooling tower, it is more effective than Air Cooled Chiller.
  •     A Water Cooled Water Chilleris more effective because the atmospheric temperature bulb temperature, which is lower than the ambient dry bulb temperature, causes condensation.
  • Because of their relative isolation from atmospheric temperature variations, itcan offer more reliable efficiency for commercial and industrial air conditioning.
  •     It varies in scale from small 20 ton models to thousands-ton models that cool the world’s biggest facilities like airports, shopping centers, and other structures.
  •     Also, it is normally stored indoors in a temperature-controlled setting. As a result, a Cooled Water Chiller has a longer lifetime.
  • For larger installations, a Water Cooled Water Chilleris normally the only alternative.

How Does the Water Cooled Water Chiller Work?

The Water Cooled Water Chiller rejects heat from a gaseous refrigerant in the condenser until it undergoes a phase transition into a liquid by using water from an exterior cooling tower.

A low-pressure refrigerant is introduced into the evaporator of Water Cooled Water Chiller to begin the process. The refrigerant is heated inside the evaporator, allowing it to change phase and become a gas.

The compressor compresses the gaseous refrigerant, raising its pressure.

The high-pressure refrigerant is routed to the condenser, which refuses heat by condensing it into a high-pressure liquid using cooling water from a cooling tower or ambient air.

The concentrated refrigerant then flows to the expansion unit of the Water Cooled Water Chiller. It has a valve that serves as a metering mechanism, reducing the flow of refrigerants in the system.

As a result, decreasing the refrigerant pressure and restarting the Water Cooled Water Chiller provides cooling.

What are the Applications of the Water Cooled Water Chiller?

Water Cooled Water Chiller is used in a variety of industries for the regulated cooling of materials, mechanisms, and factory equipment.

Injection and blow moulding, metalworking cutting oils, welding tools, die-casting and machine tooling, chemical manufacturing, and pharmaceutical formulations require the Water Cooled Water Chiller.

You may also use it in food and beverage processing, paper and cement processing, vacuum systems, analytical equipment, semiconductors, compressed air aeration, power supplies, and power generating facilities.

Water Cooled Water Chiller is also used in hospitals, hotels, and universities to cool high-heat advanced products like MRI machines, X-ray diffraction, and lasers.

What Factors to Consider Before Choosing the Best Water Cooled Water Chiller for your Application?

  • Check to see if the Water Cooled Water Chilleris packaged or split.
  • How precise is your temperature regulation, and how precise is your process?
  • What voltages options are available that are affordable?
  • What kind of fluid would it use to get cool?
  • What are the inlet/outlet temperatures of this machine?
  • Would you need to apply freeze resistance to the coolant?
  • What is the minimum amount of freeze protection?
  • How far do you think the method will move?
  • Would the Water Cooled Water Chiller necessitate the use of a mechanical pump?

What Protection Does the Water Cooled Water Chiller Control System Provide?

Low refrigerant temperature, low oil pressure, and high condensing pressure will both have an impact on and even damage the Water Cooled Water Chiller.

For this purpose, various safety controls were created to mitigate the effects of the above factors. One of the sensors is capacity controls, which keep the chilled water at a constant temperature.

The refrigerant flow controls, which are placed in conjunction with the compressor, are another form of safety control.

When these controls malfunction, the Water Cooled Water Chiller is programmed to shut down to avoid damage and injury to those in the vicinity.

How to Increase the Efficiency of the Water Cooled Water Chiller?

Chilled Water Rest

This technique entails raising the cooling water supply temperature setpoint to meet the cooling load’s requirements. In an automated Water Cooled Water Chiller controller, reset is often done as part of the control routines.

Reduce Condenser Water Temperature

Reducing the condenser water temperature reduces compressor capacity needs in the same way as raising the chilled water setpoint does.

Compressor power consumption can be reduced by 0.5 percent to 1% by lowering the temperature of the condenser water by one degree.

Monitor and Maintain the Water Cooled Water Chiller Approach Temperatures:

Condensers and evaporators in Water Cooled Water Chiller are shell and tube heat exchangers that need routine maintenance to ensure optimal heat transfer characteristics.

Solids appear to collect on internal tube surfaces when water passes into the condenser and evaporator tubes, necessitating annual “rodding” to scrape the scale and recover heat transfer coefficients.
