The water-cooled chiller is a refrigeration equipment that uses
water as the cooling medium. It mainly includes a compressor, a
condenser, an expansion valve, and an evaporator. Water-cooled
chillers generally need to be equipped with a cooling water tower
and an insulated water tank for use together. Compared with
air-cooled chillers, water-cooled chillers have better cooling
efficiency and higher accuracy of outlet water temperature.
Advantages and Disadvantages:
Advantages:
- High cooling efficiency, suitable for high-power, continuous
operation scenarios.
- Low operating noise, suitable for noise-sensitive environments.
- Longer life (lower condensing temperature, less compressor load).
insufficient:
- Depends on cooling water system, with high initial investment.
- Water quality issues (such as scale and algae growth) need to be
addressed.
- Limited use in water-scarce areas.

Choosing a suitable water-cooled chiller requires comprehensive
consideration of multiple factors. The following is a detailed
method:
1. Cooling capacity requirements
Calculate the load: First, accurately calculate the load that needs
to be cooled. For air conditioning systems, factors such as the
building area, purpose, personnel density, and equipment heat
generation need to be considered. For example, for an ordinary
office building, the cooling capacity required per square meter is
generally around 100-150W; while for a computer room with a large
number of heat-generating equipment, 300-500W or even higher
cooling capacity may be required per square meter. Based on these
data, calculate the total cooling capacity requirements, and then
select a chiller with a matching cooling capacity. It is generally
recommended that the cooling capacity of the selected chiller be
10%-20% larger than the actual calculated demand to cope with
possible peak loads.
Future expansion plan: If you are choosing a chiller for a new
building or a new production process, you also need to consider the
possibility of future expansion. For example, if the company has
plans to expand production scale, increase equipment, or expand
buildings, then when choosing a water-cooled chiller, its cooling
capacity should reserve a certain margin to meet subsequent needs.
2. Water temperature requirements
Determine the inlet and outlet water temperature: Different
application scenarios have different requirements for the inlet and
outlet water temperature of the chiller. In comfort air
conditioning, the supply water temperature is usually around 7 and
the return water temperature is around 12; in some industrial
cooling processes, such as injection molding, a lower supply water
temperature may be required, such as 4-5. Therefore, it is
necessary to determine the appropriate inlet and outlet water
temperature according to the actual purpose of use, and then select
a chiller that can meet the temperature requirements.
Water temperature control accuracy: For some occasions with high
temperature accuracy requirements, such as electronic chip
manufacturing, precision optical instrument production, etc., it is
necessary to select a chiller with high water temperature control
accuracy. Generally, high-precision chillers can control the water
temperature within ±0.5, which can better meet the requirements of
these precision production processes.
3. Energy efficiency
Check the COP value: The energy efficiency ratio (COP) is an
important indicator to measure the energy efficiency of the
chiller. The higher the COP value, the less energy the unit
consumes under the same cooling capacity. When choosing a
water-cooled chiller, you should compare the COP values of
different brands and models. Generally speaking, newer chillers
with advanced technology may have a COP value of 5-6 or even
higher, while older models or units with backward technology may
have a COP value of only 3-4. Choosing a unit with a high COP value
can save a lot of energy costs in the long run.
Consider energy-saving features: Some chillers are equipped with
energy-saving features, such as variable frequency drive
technology. Chillers with variable frequency compressors and
variable frequency water pumps can automatically adjust the
operating frequency according to the actual cooling demand,
avoiding energy waste caused by the motor always running at full
power. For example, when running at part load, the variable
frequency chiller can reduce the speed of the compressor and water
pump, thereby reducing energy consumption, which can bring
significant energy-saving effects in actual use.
IV. Reliability and stability
Brand and reputation: It is usually more secure to choose a
water-cooled chiller from a well-known brand. Well-known brands
generally have a long production history and rich experience, and
their products have been tested by the market and are more
trustworthy in terms of reliability. You can learn about the
reputation of different brands by checking industry reports, user
reviews, and consulting professionals.
Working Principle:
The working principle of the water-cooled chiller is to compress
the low-temperature and low-pressure refrigerant gas into a
high-temperature and high-pressure gas through the compressor, and
then radiate the high-temperature and high-pressure gas through the
condenser to condense it into a high-pressure liquid, and then pass
the expansion valve to make the high-pressure liquid It expands
into a low-pressure liquid and flows into the evaporator to
complete the refrigeration cycle.
In the water-cooled chiller, water is used as the cooling medium,
and is connected to the cooling equipment through the water
pipeline, and the refrigerant gas after heat dissipation absorbs
heat and turns it into a low-temperature and low-pressure gas,
thereby realizing refrigeration.

wooden boxes. All components are secured and protected with a film,
and the unit is then placed on a pallet for easy transport. And
affix the shipping mark information label on the wooden box to

Water-cooled chillers are suitable for scenarios with high
requirements for cooling efficiency, long operating time and water
system conditions, but attention should be paid to water quality
management and regular maintenance. When selecting a model, it is
necessary to comprehensively evaluate cooling requirements,
environmental conditions and long-term operating costs, and consult
professional engineers when necessary.
