Cooling capacity refers to the cooling capacity generated by the normal chiller. It is generally expressed in KW and also used as CAL.


Refrigerant is the fluid in the refrigerant circulation of water chiller, R22, R404 and so on. Power consumption and power supply are indicated on the nameplate.

 

Water cooled chiller is the use of water cooling unit heat dissipation, in operation through refrigerant circulation constantly produce gas phase change, heat absorption and heat release phenomenon, promote the alternating cycle of hot and cold, so as to take away the heat in industrial production, to achieve cooling.

 

There are many kinds of chiller classification, such as the water cooler, there can also be air cooler, screw chiller, explosion-proof chiller, integrated chiller, water cooler box chiller and so on. But the basic composition is roughly the same, compressor, condenser, expansion valve, evaporator, electronic control system, water pump, flow meter, high and low pressure meter, dryer, oil and water separation device and so on.

 

How to calculate the refrigerating capacity of industrial equipment? The following points should be calculated in detail.

1, according to the temperature change of industrial production material calculation cooling capacity.
2. Calculation of calorific value of equipment.
3, water flow, water pressure, water volume, water quality requirements and other special environment to determine.
4. Determine the operating environment of the equipment, such as the industrial production with water tower, water cooled chiller can be preferred.

 

It is usually used to calculate how much the cold water machine should be equipped with P, but the most important thing is to know the rated cooling capacity. The general air cooling of 9.07KW is to choose a 3P machine. And so on.

Choose the right pump:


Water pump includes cooling water pump (water-cooled chiller) and frozen water pump, the selection of water pump, the purpose is to achieve enough head and water flow, water pressure, power should meet the requirements of industrial refrigeration, especially in the parallel operation of the pump, the flow attenuation, so the selection of multiple pumps, to consider the attenuation of the flow, leave a margin.

 

Design and selection of cooling tower:
The number of cooling towers corresponds to the number of refrigeration hosts. The water flow rate of the cooling tower is usually calculated as 1.2 times of the cooling water volume. Assuming that the cooling water volume of the chiller system is 160m3/h, the cooling water volume of the cooling tower =160×1.2=192m3/h, and the cooling water volume in the cooling tower parameter table is 200m3/h.

 

In addition, the selection of water filter and water tank should be appropriate according to the water quality in the operating environment. If necessary, the water softening device of the water chiller system should be added, and the water source with better water quality should be used to avoid the operation problems of the water chiller.


Industrial chiller has a wide range of applications, its temperature range :+20℃-25℃ adjustable, special temperature environment, can achieve a low temperature environment of minus 160 degrees. Widely used in various industrial production.

Like the chemical industry; Plastic products, plastic containers, films, plastic steel profiles, pipes, wires, cable sheathing, tire industry, electroplating and machine tool cutting liquid cooling industry, pharmaceutical industry, electronics industry, hardware industry, food and beverage industry, shoe industry, laboratory, medical equipment, optical instruments, etc.
