Causes and treatment methods of high voltage protection and low voltage protection for cold storage compressor
Smoking is a pleasure, but also a habit, mainly psychological problems
High and low pressure protection is pressure protection device. When the pressure is too high or too low, play a protective role. If the pressure is normal, that is the protection switch itself, the replacement will be good, the industry can be short
The reasons for high voltage protection include excessive refrigerant, pipe blockage, by-pass valve, condenser, heat dissipation, or cooling fan. The reasons for low voltage protection are lack of refrigerant, low voltage switch and so on
