8-23 What is the pressure range of high and low pressure of refrigerant?

The pressure range of high and low pressure of refrigerant is regulated by national standards. High pressure should be 1.4~2.5MPa, and low pressure 0.4~0.55MPa. Adjustments are needed if pressures are out of range to ensure normal operation.

Butiran Kes

Answer: There are national standards for the pressure of condenser of refrigeration equipment. High pressure of refrigerant is called condensation pressure, and its reading should be 1.4~2.5MPa. If it is lower than this range, check and adjust the cooling water volume; low pressure is called evaporation pressure, which usually ranges from 0.4~0.55MPa. If it is not in this range, the screw of hot gas bypass valve should be adjusted.

In normal operation, the condensation pressure of R22 should not exceed 1.5MPa. Long-term operation under high condensation pressure will affect the service life of refrigeration compressor. In addition, the dryer is equipped with high pressure protection device.

However, those with sealed components, including motors, controllers, and connectors, can also be operated outdoors. Performance IC forklifts tend to be utilized in heavy-duty applications, such as brick and lumber yards, where larger capacity and performance is required to move the heavy loads.
