What is the cause of the high and low pressure failure of the chiller

High-pressure faults often occur together with high temperature, or are mutually induced-high pressure may lead to high temperature, while high temperature will always cause high-pressure faults. High-pressure faults and high-temperature faults often occur at the same time.

Other causes of high pressure failure include: reduced condenser heat transfer efficiency, poor cooling system heat dissipation, evaporator failure, thermal expansion valve blockage, low refrigerant, heavy load on the refrigerator compressor, lack of refrigerated lubricating oil, and other possibilities.
