A Water Cooled Centrifugal Chiller as a prefabricated machine is used in the manufacturing industries of aircraft, ships, and vehicles.

In this buying guide, we will go through some important aspects related to Water Cooled Centrifugal Chiller.

What is a Water Cooled Centrifugal Chiller?

A Water Cooled Centrifugal Chiller uses water as a medium to provide cooling in different industrial applications. It is an aerodynamic or turbine-type refrigeration system.

It moves the gas by changing rotational kinetic energy to dynamic energy.

A Water Cooled Centrifugal Chiller uses a vapor compression cycle to cool the water and removes the heat absorbed by the chilled water.

It also removes the heat from the compressor to a re-circulation of a water loop cooled by a cooling tower. It processes the water in a centrifugal refrigeration circuit to generate cooling.

It works with a direct current motor drive and uses magnetic bearing technology.

A Water Cooled Centrifugal Chiller is mostly used in semi-conductor, food, chemical, and automotive industries.

Its compressor uses multiple prime movers which include DC motors, AC motors with frequency varying drives, diesel engines, gas turbines, and steam turbines.

By regulating the speed of the centrifugal compressor you can enhance the capacity of the Water Cooled Centrifugal Chiller.

A variable inlet guide vane can be used for capacity control for a water-cooled chiller system.

What is the Working Principle of a Water Cooled Centrifugal Chiller?

Water Cooled Centrifugal Chiller is a refrigeration machine. It utilizes the vapor compression principle to cool the water.

It also removes the heat from the chilled water and compressor by using cooling towers. It has two working circuits.

  1. Centrifugal Refrigeration Circuit

The centrifugal refrigeration circuit of a Water Cooled Centrifugal Chiller is used to cool down the water that is used as a heat exchange medium.

It has four major components compressor, condenser, evaporator, and expansion valve.

All these components perform specific functions.

  1. Water Circuit

The water circuit of a Water Cooled Centrifugal Chiller is used to cool down your application by flowing chilled water through your application.

It consists of a reservoir tank, water boxes, pump, filters, and a heat exchanger.

The refrigeration cycle of a Water Cooled Centrifugal Chiller starts from the endothermic process of evaporation.

In this process, the refrigerant is boiled and changes its state from liquid to gas.

This gas is then sent to the compressor which is composed of a prime mover and a centrifugal compressor.

It then converts the kinetic energy of the gas into pressure by raising its temperature and pressure.

This processed refrigerant is then sent to the heat exchanger for condensation. There it processes the refrigerant and removes heat from it.

In the process of condensation, the refrigerant is condensed from a gas state to a liquid. It takes away the extra heat to the cooling tower where heat is dissipated to the atmosphere.

After the exothermic process of condensation, the liquid refrigerant is driven through a device known as an expansion valve that reduces the pressure of the liquid.

What are the Components of Water Cooled Centrifugal Chiller?

The major components of a Water Cooled Centrifugal Chiller are;

  • An Evaporator
  • A Centrifugal Compressor
  • A Condenser
  • An Expansion Valve
  • Water Boxes
  • Control Panel
  • Power Unit
  • An Evaporator

A Water Cooled Centrifugal Chiller uses a shell and tube-type evaporator that acts as a heat exchanger.

An evaporator dissipates the heat from incoming water. It requires heat to change the processed liquid into a gas.

A flooded evaporator is highly energy efficient in this regard. This chilled water then circulates it in the tube.

A refrigerant submerges the tubes in the shell completely.

  • A Centrifugal Compressor

A Centrifugal Compressor is responsible for converting rotational kinetic energy to the dynamic energy of flood flow.

The refrigerant in the process begins to the pump impeller and flows outwards in the radial direction and then exits.

It uses magnetic bearing technology and a DC motor.

The main components of a centrifugal compressor are casing and inlet, impellers, diffuser, and collector.

The centrifugal compressor of a Water Cooled Centrifugal Chiller can be of two types; Single stage centrifugal compressor and Multi-stage centrifugal compressor.

  • A Condenser

Just like a tube and shell-type evaporator, the condenser is also a shell and tube heat exchanger.

The condenser dissipates the heat from the refrigerant gas and condenses it into a liquid and ejects the excess heat to the atmosphere.

  • An Expansion Valve

An expansion device is used to reduce the pressure of the refrigerant liquid.

You can choose a simple orifice plate or an electronic modulating valve for higher efficiency.

  • Water Boxes

The water boxes are mounted to the evaporator and condenser.

The main purpose of water boxes is to segregate the inlet and outlet. They can be open-ended or closed-ended.

  • Control Panel

The control panel of a Water Cooled Centrifugal Chiller monitors.

The overall performance of the system and generates alarms in any irregular condition to prevent big loss.

It is placed on your Water Cooled Centrifugal Chiller.

  • Power Unit

The power unit controls the electricity flow throughout the components of the Water Cooled Centrifugal Chiller.

It is usually composed of a starter, speed controller and circuit breaker, etc.

What are the Main Features of Water Cooled Centrifugal Chiller?

Features of Water Cooled Centrifugal Chiller:

Folding features makes your Water Cooled Centrifugal Chiller prominent from others.

  1. High Cooling Capacity.

The main feature is its centrifugal compression, which provides a high cooling capacity.

It operates via an impeller, much like a water pump. The impeller compresses the refrigerant.

  1. Longer Lifespan

A Water Cooled Centrifugal Chiller doesn’t need replacement as often as an air-cooled centrifugal chiller.

  1. Inaudible Operation

Water Cooled Centrifugal Chiller operates smoothly and quietly. The flow of water throughout the system doesn’t result in the same noisy expansion and contraction that you can hear in the air-cooled chiller.

Quiet operation is particularly important in some environments such as hospitals and schools, where noise can cause disturbance to occupants.

  1. Energy Efficiency

The film coefficient is 10 to 100 times better in Water Cooled Centrifugal Chiller versus other chillers consumes very low electrical power.

This means that a water-cooled chiller transfers heat more efficiently. The result is savings in energy costs.

  1. No Open Space Needed

Water Cooled Centrifugal Chiller is placed inside buildings, which makes them ideal for companies that don’t have access to enough outdoor space.

While Air-cooled centrifugal chiller needs to stay outdoors in an open space with plenty of fresh air to operate.

  1. Safety

A water cooled chiller uses water as a refrigerant instead of toxic chemicals. This makes it safer for people who operate it.

  1. Two Compressors

The Water Cooled Centrifugal Chiller can be used with two compressors to further enhance the capability of your application.

  1. Close Loop Control Operation

Closed-loop control operation of the water-cooled centrifugal system provides very precise and accurate control of cooling rate which is very much essential for some industries like the plastics industry.

What are the advantages of a Water Cooled Centrifugal Chiller for your Application?

The water cooled chiller is cooled by Freon refrigerant to perform the endothermic process of evaporation in the evaporator to absorb the heat of refrigerant water.

The Freon wet steam after evaporation is compressed into high-temperature and pressure gas by the centrifugal compressor.

It condenses in the water-cooled condenser of Water Cooled Centrifugal Chiller and turns into liquid. After that, it enters the evaporator for recycling through the expansion valve throttle.

Hence, making 7 degree Celsius to 12 degrees Celsius air terminal air conditioning chilled water supply.

Some of the Advantages of a Water Cooled Centrifugal Chiller for your Application:

  1. A Water Cooled Centrifugal Chiller offers a high-speed rotating impeller to perform more efficiently without wasting energy.
  2. It has a large gas transmission capacity and large single machine capacity for your application.
  3. A Water Cooled Centrifugal Chiller has less vulnerable parts and delivers reliable cooling effects.
  4. Its compact structure, smooth operation, small vibration, low noise adds to its high efficiency.
  5. A Water Cooled Centrifugal Chiller features a small weight index of unit refrigerating capacity.
  6. The refrigerant is not mixed with lubricating oil, evaporator, and condenser of good heat transfer performance.
  7. EER value of a Water Cooled Centrifugal Chiller is higher than an air-cooled centrifugal chiller, which can be adjusted continuously within 10%~100%.

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

The main reason for their difference is their condensers, the way of heat dissipation.

A Water Cooled Centrifugal Chiller has a cooling tower so it features higher efficiency than an air-cooled centrifugal chiller.

Another reason for its higher efficiency is that it condenses the refrigerant on the ambient temperature wet bulb temperature, which is less than the ambient dry bulb temperature.

The lower condensation means higher efficiency. A Water Cooled Centrifugal Chiller has some additional components like cooling towers, condenser water pumps, makeup water pumps, or TES reservoirs.

It is usually smaller in size as compared to air cooled centrifugal chiller.

While air cooled centrifugal chiller is used where there is water shortage. It uses a current of ambient air.

It uses air as a medium to provide a cooling effect to different industrial applications. It has a lower refrigerant condensing temperature than Water Cooled Centrifugal Chiller.

How to Calculate the Efficiency of Water Cooled Centrifugal Chiller for your Application?

The efficiency of a Water Cooled Centrifugal Chiller depends on the amount of energy consumed and the cooling delivered.

You can calculate the efficiency of Water Cooled Centrifugal Chiller for your application.

The complete method of calculating the efficiency of a chiller is not rocket science; the efficiency of a Water Cooled Centrifugal Chiller is measured in “Coefficient of Performance” also known as COP.

The coefficient of performance is the ratio between the amount of cooling effect a Water Cooled Centrifugal Chiller produces and the amount of electric power is consumed to produce cooling.

Both of these values should be measured in KW (Kilowatts).

For example:

A Water Cooled Centrifugal Chiller that produces 2300KW of cooling or 7,847,924.7 BTUs per Hour in metric units. The electrical power requirements to generate this are 450KW.

The metric calculation of the efficiency of a Water Cooled Centrifugal Chiller will be;

2300KW/ 450KW = 5.1. The COP is 5.1, which means that every 1kw of electric power is input, which will produce 5.1KW of cooling effect.

Remember one thing that the coefficient of performance varies with the cooling load on different chillers.

The manufacturer of Water Cooled Centrifugal Chiller should be able to give the design data of COP.

So, you can compare it with the performance of your Water Cooled Centrifugal Chiller to diagnose operational issues.

  1. High-Pressure Discharge

High-pressure discharge is very common in Water Cooled Centrifugal Chiller and its main cause is bad water treatment systems. Make sure your building has a strict water treatment.

Low-Pressure Discharge

One issue that causes low-pressure discharge is if the suction valve is partially closed, so check that. It’s uncommon but it could happen.

Refrigerant undercharge can cause low-pressure discharge.

You will need to make checks on the system to that it has enough refrigerant charge. If you find any problem, then it needs to be topped up.

Low Suction Pressure

The low suction pressure could be down to a low refrigerant charge. Check out your centrifugal refrigeration system signs of this and top up if needed.

Don’t forget to check for leaks as well. If the pressure becomes too high in the Water Cooled Centrifugal Chiller, it might have vented through the safety relief valves.

High Suction Pressure

Now if you experience a high-pressure warning on the suction line.

It happens when the excessive load is probably the main one and that is where the cooling load is just too much for the Water Cooled Centrifugal Chiller to handle.

FAQ of Water Cooled Centrifugal Chiller.

What is Centrifugal Phenomenon in a Water Cooled Centrifugal Chiller?

The centrifugal force in a Water Cooled Centrifugal Chiller is an inertial force that acts on all objects when viewed in a rotating frame of reference.

It is directed away from an axis of rotations and passes through the coordinate system’s origin.

Why Water Cooled Centrifugal Chiller is more Popular?

Water Cooled Centrifugal is Chiller is popular in the family of industrial chillers because it provides a very rapid heat exchange rate due to its centrifugal compressor.

How to Convert British thermal units in Tons?

BTU is an abbreviation of a British thermal unit, and one British thermal unit (BTU) is the amount of heat used to raise or decrease the temperature of one pound of water by 1 degree Fahrenheit.

12000 BTUs   One Ton

For example, if a Centrifugal Water Cooled Chiller has a cooling capacity of 18000 BTU, The capacity in Tons will be

18000/12000 1.5 Tons
