The reason for the condenser is the reason for the high pressure on the high pressure side

Se o chiller refrigeration system fails, the number of gaseous refrigerant molecules will change greatly, and the pressure will be abnormal, which is far beyond its normal pressure working range.

The main reasons for the poor heat dissipation of the condenser resulting in the high pressure on the high pressure side and the poor heat dissipation of the chiller heat exchanger are as follows:

1. There is fouling in the condenser tube;

2. There is dust on the surface of the condenser radiator

3. The condenser radiator is blocked;

4. The air volume is not good

These reasons will affect the heat exchange between the refrigerant and the carrier. The refrigerant cannot release heat very well, and the gaseous refrigerant will hardly condense into a liquid refrigerant. In this way, the gaseous refrigerant continuously transported from the compressor has no time to condense, and the gaseous refrigerant accumulates between the compressor and the condenser. The number of gaseous refrigerant molecules on the high-pressure side gradually increases, causing the pressure on the high-pressure side to continue to rise.

When the operating conditions of the chiller change, the number of gaseous refrigerant molecules changes and the pressure changes accordingly. For example, when the compressor speed increases, the gaseous refrigerant delivered to the condenser increases, causing the gaseous refrigerant on the high-pressure side to be added, and the pressure rises accordingly. The number of gaseous refrigerants sucked increases, which reduces the gaseous refrigerant on the low-pressure side, and the pressure decreases accordingly; if the speed of the condenser fan speeds up and the air volume increases, the gaseous refrigerant in the condenser is condensed into the number of molecules of liquid refrigerant. If the speed of the evaporator fan speeds up and the air volume increases, the number of molecules that evaporate the liquid refrigerant into gaseous refrigerant will increase, and the gaseous refrigerant on the low pressure side will increase accordingly, and the pressure will decrease. Elevated.
