How Does a Water Cooled Chiller System Work?

How does a water cooled chiller work?

water cooled chiller system uses water and the refrigeration cycle to achieve cooling.

In other words, it helps to cool your machines or room.

How a typical GesonChiller water cooled chiller working principle.

The cooling process cools down the water from the evaporator, once the refrigerant gets to the important part of the refrigeration cycle.

Then, a pumping machine will circulate it from the chiller system to the process.

Because the water is cool, it will absorb heat from the process and become warm, then it returns to the chiller.

So the water is the secondary refrigerant, water cooled chiller systems remove heat from processes or rooms, achieving cooling.

water chiller working principle

water cooled chiller working principle

Does it need a water-cooling tower?

Yes, you should also use a water-cooling tower.

Besides, you also need a water-cooling pump, water cooling pipes for the condensing system.

What Kind of Water is used in a Water Cooled Chiller?

The two most common types of water in water cooled chillers are plain water and glycol-water solution.

Both types of water have their own pros and cons.

Sometimes specific oils are used to cool processes in very special circumstances.

Plain water is regarded as an economical and efficient cooling liquid. It does not have minerals.

The most preferred “water”, however, is the glycol-water solution.

Glycol is a coolant making the glycol-water solution very efficient.

This solution also doesn’t freeze easily.

This makes it appropriate for locations where freeze protection is necessary.

What is a Sea Water Cooled Chiller?

If your site near to the seaside, and seawater is available.

You can use the sea water as chilled water.

The sea water is salty, so it will need a special design evaporator heat exchanger.

It will help reduce the operating cost for factory manufacturing.

How to Design the Whole Chiller Cooling System?

What is the Difference between a Water Cooled Chiller and a Condenser?

Comparing a water cooled chiller and a condenser is like comparing apples to oranges.

The two are not on the same level to be compared. They are different.

Most water cooled chiller systems have a condenser component.

This component is important because it is needed for the refrigeration cycle.

So the relationship between a water cooled chiller and a condenser is that one is part of the other.

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

The main differences between water cooled chiller vs air cooled chiller.

Are different heat-exchange media, different design principles, and different installation methods. The details are as follows:

1. Different heat exchange media

1. Air-cooled chiller

The medium of heat exchange is air, which uses special fans for chillers and variable-frequency axial fans, so it is called air-cooled

2. Water-cooled chiller

The use of water to exchange heat requires the installation of a special cooling tower for the chiller. The source is water, and the special cooling tower is equipped, so it is called “water cooling”.

Two, the design principle is different

1. Air-cooled chiller

The air-cooled machine takes away heat through the flow of air,
and the air through the condensing coil to take away the heat,
and the refrigerant inside the machine is cooled.

2. Water-cooled chiller

Through the cooling water circulation of the water cooling tower,
the heating is taken away,
then the chilled water is chilled.

Three, the installation method is different

1. Air-cooled chiller

The air-cooled chiller is movable, without auxiliary accessories,
and can be directly placed outdoors.
It does not need a machine room.

2. Water-cooled chiller

Need to be equipped with cold water tower and pool, water pump, machine room, need to be placed indoors.

The role and requirements of cooling towers and cooling pumps

  1. The high-temperature cooling water from the water-cooled chiller, the cooling pump sends the high-temperature cooling water from the chiller to the cooling water tower
  2. The cooling tower returns to the chiller after cooling the cooling water
  3. The pressure difference between the cooling water inlet and the cooling water return water is about 3-4kg.

The role and requirements of the refrigeration pump.

  1. The role of the refrigerating pump is to deliver low-temperature chilled water to the client, and then return to the chiller after the heat is exchanged
  2. The pressure difference between inlet and return water is about 3-4kg

The role and requirements of the water-cooled chiller.

  • 1. Function: absorb the heat of high-temperature chilled water and transfer it to low-temperature chilled water
  • 2. The temperature difference between freezing and cooling water is 4-6 degrees Celsius

Principle of the water-cooled chiller system.

  • 1. The cold water produced by the water-cooled unit is sent to the client through the refrigeration pump, exchanged with the cold water with a higher temperature, and returned to the chiller.
  • 2. Then the heat of the high-temperature chilled water is transferred to the low-temperature cooling water through the chiller, and the cooling water becomes the high-temperature cooling water.
  • 3. The high-temperature cooling water is sent to the cooling tower through the cooling pump, and the heat is discharged to the outdoors through the cooling tower, turning into low-temperature cooling water and returning to the chiller.

Start sequence of water-cooled chiller system

  1. Open the cooling and freezing pumps water inlet and outlet valves
  2. Open the chiller water inlet and outlet valves
  3. Open the cooling tower water inlet and outlet valves
  4. Start the cooling tower
  5. Start the cooling pump
  6. Start the refrigeration pump
  7. Start the chiller

The reason for opening the inlet and outlet valves of the main engine, cooling pump, refrigeration pump, and cooling tower first

  1. The refrigeration of the water-cooled chiller system is mainly transmitted by water
  2. Water is transported by pumps and pipes
  3. Therefore, before the water pump is started, the valve should be opened first to ensure the smoothness of the pipeline.
  4. If the pipeline is blocked, once the water pump starts. The pipe will burst under huge water pressure

Turn on the cooling tower again, turn on the cooling pump, turn on the refrigeration pump, and turn on the water-cooled chiller.

  • 1. The cooling tower must ensure that the cooling water can dissipate normally
  • 2. The cooling pump must ensure that it can circulate and absorb the heat conducted by the chiller
  • 3. The refrigeration pump must ensure normal circulation and release heat through the chiller

Water-cooled chiller system refrigeration system stop sequence

  1. Stop the chiller host
  2. Stop the refrigeration pump
  3. Stop the cooling pump
  4. Stop the cooling tower
  5. Close the cooling pump and the water inlet and outlet valves of the refrigeration pump
  6. Close the inlet and outlet valves of the chiller host
  7. Close the water inlet and outlet valves of the cooling tower

Comparison of water-cooled screw unit and lithium bromide unit

1. The advantages of water-cooled screw chillers

Water-cooled screw chiller is a kind of refrigeration unit that uses water as the cold source (exhaust heat source). The compressor is screw type. It has two water systems, namely the chilled water system to the air-conditioning room; and the cooling water for heat rejection System, the cooling water system is equipped with a cooling tower or uses ground water.

Features of this unit:

1. It can only be used as a single cooling machine, not heating. Boiler or urban heating network must be used for heating in winter

2. Small size, large capacity, compact structure, smaller than a lithium bromide unit with the same capacity.

3. The high efficiency ratio is generally 4.4, and the highest can reach 4.8, which is significant in energy saving.

4. It can automatically adjust the output corresponding cooling capacity according to the heat load of the air conditioner. There are 25%, 50%, 75%, 100% stepless energy adjustment and 0~100% stepless energy adjustment. Significant energy saving, avoiding energy waste.

5. The compressors used in water-cooled screw chillers are produced by world-renowned manufacturers Taiwan Fusheng and Taiwan Hanbell. Four-way reversing valve, expansion valve, solenoid valve, check valve, stop valve, sight glass and other valve parts are also produced by world-renowned manufacturers, such as American Aike Company, Japan Saginomiya Company, Danfoss Company of Denmark, etc. The unit is of high quality, reliable performance, and a life span of 15 to 20 years.

6. ​​Fully automated, computer controlled, no need for human supervision.

It is widely used in summer air conditioning of large buildings such as office buildings, hotels, restaurants, hospitals, schools, dance halls, theaters, residential buildings, shopping malls, etc. The water-cooled screw chiller produced by our company has 11 specifications, with a capacity of 110~3200KW, and a single unit can supply 1300~8000 m2 of building air conditioning. Multi-functions can be used for air conditioning in buildings of tens of thousands of square meters.

The characteristics of lithium bromide unit

1. The service life and cooling capacity attenuation of the unit

Lithium bromide chillers have high vacuum requirements, but limited to the current technological level of some companies, it is difficult to maintain a high vacuum for a long time.

According to relevant information, for a unit of 100×104kcal/h, if 20 grams of air leaks in, the unit cannot be cooled.

In actual projects, there have been instances where refrigeration cannot be performed for the first time in official operation.

In the presence of air, the lithium bromide aqueous solution is very corrosive to the materials used in the manufacture of lithium bromide units, such as carbon steel, copper and other metals. If the vacuum of the unit is not well guaranteed, the unit will soon be scrapped.

The life of lithium bromide units produced by general manufacturers is only about 10 years without reliable materials and technical guarantees.

Due to corrosion, fouling, blockage, reduced vacuum and other reasons, the cooling capacity of lithium bromide units has a large attenuation.

The units produced by manufacturers with general conditions have the problem of cooling capacity attenuation, and some cooling capacity attenuation reaches 15-20% per year.

Some manufacturers, due to the use of some special technical processing, and the sample calibration value is lower than the maximum refrigeration capacity of the refrigerator, so that the actual cooling capacity attenuation during operation is not significant.

There are also individual manufacturers who claim to have no cooling capacity attenuation, which should be the goal and guarantee for unit production in the future.

For the problem of cooling capacity attenuation, engineering designers must make correct judgments after site inspection and in-depth understanding, and include them in the selection calculation, otherwise problems will occur during long-term operation.

Although the air-conditioning load of some projects is too large or too large to cover up the seriousness of this problem, you should keep a clear understanding of each account.

2. Energy consumption and power consumption of the unit

Since the lithium bromide chiller achieves the purpose of cooling at the expense of heat energy, its power consumption is very small (only about 2% of the compression type), but its heat consumption per unit of cooling capacity is large, that is, its refrigeration coefficient Smaller, the current domestic maximum value is only about 1.2, while the compressor unit is above 3.5.

Therefore, the lithium bromide unit only uses less electricity and cannot save energy.

Therefore, the best use conditions for this unit are occasions with waste heat, waste heat or power shortage areas, and its development cannot replace compression refrigeration, but can only be developed accordingly.

Chilled water outlet temperature in practical applications, the level of chilled water temperature affects the determination of air-conditioning methods, the layout of air-conditioning systems, and the selection and calculation of air-conditioning equipment.

Most of the air-conditioning equipment information we usually encounter is based on the supply and return water temperature of 7/12℃.

If the chilled water prepared by the lithium bromide chiller in the actual project is 10/15℃, the cooling capacity of each air conditioning equipment and the final state point of air treatment must be rechecked and calculated.

For some engineering designs, since the main air-conditioning and refrigerating machine room are not designed by the same unit, and the main body is followed by the machine room, the above situation may occur at this time.

If the outlet water temperature of the chiller does not meet the main design requirements, the main air conditioner cannot be guaranteed.
