What factors affect the cooling capacity of the chiller

Industrial production is inseparable from the chiller. Usually, the cooling capacity of the chiller refers to the nominal cooling capacity of the chiller, which refers to the cooling capacity when the ambient temperature is 35 degrees and the water outlet temperature of the chiller is 7 degrees. . So what factors affect the cooling capacity of the chiller?

1. The power of the compressor: the higher the power, the higher the cooling capacity. According to the size of the model, choose a compressor with different mechanisms, such as piston type for small chillers, scroll type for medium size, and screw type for large size. , centrifugal, etc.

2. Low coolant content: If the coolant content is too low, the equipment will not be able to absorb oil, and the cooling effect will be reduced. Solution for low coolant content: Check the coolant frequently to see if the coolant level is maintained between high and low, and add coolant in time when the coolant is too low.

3. Water temperature (evaporation temperature is different, cooling capacity is different): the higher the water temperature, the greater the cooling capacity, and the lower the water temperature, the smaller the cooling capacity.

4. Filter blockage: After the filter screen is blocked, the dust on the condenser will accumulate more and more, which will affect the cooling effect of the refrigeration equipment over time. If things go on like this, it may even lead to the refrigeration equipment not being able to cool down. The solution to the blockage of the filter: Clean the filter regularly or irregularly.

5. Lack of Freon: In some early refrigeration equipment using Freon as a refrigerant, Freon will volatilize after a long time of use, thus affecting the refrigeration effect. Solution: Remind you that freon may be harmful to human body, so in this case, you should find a professional maintenance company to add it.

6. Power supply voltage: the voltage is low or the power of the refrigeration equipment is not enough.

7. Pump power: the amount of water circulation directly affects the heat transfer rate.

8. Evaporator: The form of condenser is divided into water tank coil test, shell and tube type, stainless steel plate type, etc.

9. Thermal material: copper tube has the best heat transfer.

10. Pipeline: There is a problem with the pipe.

What factors affect the cooling capacity of the chiller will be shared here. In addition, when the chiller is actually running, due to the difference between the ambient temperature and the outlet temperature of the chilled water, the cooling capacity and the power consumption of the compressor also change. That is to say, the cooling capacity of the chiller, the outlet water temperature and the ambient temperature are also affected.
