The cooling capacity of an water cooled chiller is related to many factors. In this article, we will delve into the key factors affecting the cooling capacity of a industrial water cooled chiller in terms of compressor power, coolant content, cooling water temperature, supply voltage, pump power, etc. to help you maximise your understanding and improve the cooling efficiency of your industrial water chiller machine!

The compressor of a water cooled chiller

The compressor is one of the crucial components in water cooled chillers, and its power and type have a direct impact on the cooling capacity.

●The higher the power of the compressor, the higher the refrigeration capacity; while the lower the power, the refrigeration capacity decreases accordingly.

●Common compressor types in water cooled chillers include piston, scroll, screw, and centrifugal. These types of compressor power are different, piston compressor power is smaller, suitable for small refrigeration capacity chillers;

●Centrifugal compressors are more powerful and are suitable for large cooling capacity chillers. According to the specific needs and refrigeration capacity requirements, selecting the appropriate compressor type and power can ensure the efficient refrigeration performance of water cooled  chillers.

The refrigerant type of a water cooled chiller

In the process of the refrigeration cycle, the refrigerant transmits and absorbs the medium of heat in the system, thus ensuring the cooling effect of the industrial chiller. Different refrigerants also have a certain impact on the cooling capacity

●Common refrigerant types in industrial chillers include: R22, R407C,R410A,R404A,R134A.

●R22, R404C, and R134A are non-environmentally friendly refrigerants with relatively low refrigeration efficiency.

●R407C, and R410A are environmentally friendly refrigerants with relatively high refrigeration efficiency.

The heat exchanger of a water cooled chiller

The heat exchanger is the key component of an industrial water cooled chiller to transfer heat, it contains evaporator and condenser two parts. The size, form, and material of the heat exchanger have a direct impact on the cooling capacity.

●Size of heat exchanger

The size of the heat exchanger is determined by the industrial water cooled chiller compressor power. The larger the compressor power, the larger the heat exchanger size; the smaller the compressor power, the smaller the heat exchanger size.

●Heat exchanger form

Common heat exchangers for industrial water cooled chillers include plate heat exchangers, coiled tube heat exchangers, and shell and tube heat exchangers.

Plate heat exchanger has the best heat transfer effect, coil heat exchanger has the second best heat transfer effect, and shell and tube heat exchanger has the lowest heat transfer effect.

Heat exchanger material

In industrial water chiller machine, common materials for heat exchangers include copper, stainless steel, and titanium alloy. The following is a comparison of several heat exchanger materials:

The coolant of a water cooled chiller

Coolant is usually water or other liquids used to absorb or carry away heat inside the cooling system to maintain the cooling efficiency of the refrigeration equipment. The level of coolant affects the cooling capacity of industrial water chiller machine.

●Coolant level is too low, the refrigerant may not be able to absorb the heat inside the system, thus reducing the cooling effect of the water cooled chiller

The cooling water temperature of a water cooled chiller

The cooling capacity of the industrial water cooled chiller is closely related to the evaporation temperature of the refrigerant, while the cooling water temperature directly affects the evaporation temperature of the refrigerant.

●The higher the cooling water temperature, the greater the cooling capacity of the industrial water cooled chiller

●The lower the cooling water temperature, the smaller the cooling capacity of the industrial water cooled chiller

The cleanliness level of the water-cooled chiller's filter mesh.

The filter screen is mainly used to keep the surface of the condenser clean by preventing the entry of dust, dirt, and other impurities on the surface of the condenser. The cleanliness of the filter will affect the cooling capacity of the industrial water chiller machine.

●The cleaner the filter, the better the heat dissipation of the condenser, and the better the cooling effect of the industrial water cooled chiller

●Once the filter mesh is blocked, it will lead to dust and dirt can not be effectively filtered, enter the condenser and accumulate, and the dust accumulated on the condenser will hinder air circulation, reduce the cooling efficiency of the condenser, thus affecting the cooling effect of the water cooled chiller

The water pump power of a water cooled chiller

The water pump is a key component in the water cooled chiller, and its role is to pump the cooling water from the water tank or cooling water tower and transport it through the pipeline to the evaporator or condenser for circulation. The circulating cooling water takes away the heat inside the cooling system to achieve the cooling effect. The power of the water pump has an effect on the cooling capacity of the industrial water cooled chiller.

●A more powerful water pump provides higher water pressure and flow rate, thus increasing the amount of water circulated.

●The higher the water circulation volume in the cooling system, the faster the heat transfer rate and the better the cooling effect

The power supply voltage of a water cooled chiller

The stability of the supply voltage directly affects the operating efficiency of the compressor, the cooling effect of the condenser, and the stability of the whole system, which in turn has an impact on the cooling capacity of the commercial water  chiller.

●If the supply voltage is low, the compressor may not be able to reach the rated speed and working pressure, thus reducing the efficiency of the refrigeration cycle and affecting the cooling capacity of the commercial water chiller.

●If the supply voltage fluctuates greatly, the condenser may not be able to work properly, thus affecting the efficiency of heat dissipation and thus affecting the cooling capacity.

●If the supply voltage is unstable, it may cause the refrigeration system to malfunction or the performance to drop, thus affecting the cooling capacity.

Enhancing the refrigeration performance of the chiller through routine maintenance and servicing.

●According to the refrigeration demand, choose the appropriate power compressor

●Regularly check the liquid level of the chiller tank, if the liquid level is lower than the standard line, add it in time.

●Select R407, R410A, and other environmentally friendly and efficient refrigerants.

●Regularly clean the heat exchanger filter

●Choose the right power of the water pump, regular inspection, maintenance of the water pump
