The method of saving the power consumption of commercial refrigeration

The method of saving the power consumption of commercial refrigeration: First of all, commercial refrigeration cannot be bought too much, because the larger the commercial refrigeration, the more power it consumes. Under normal circumstances, it is enough for a family of 5 to buy a commercial refrigeration with a volume of 300 to 400 cubic decimeters. Second, the placement of commercial refriger...

Supermarket display cases New analysis of industry technology

Supermarket display cases Compressor is the heart of the refrigeration system. It sucks in low-temperature and low-pressure refrigerant gas from the suction pipe. The motor drives the piston to compress it and discharges high-temperature and high-pressure to the exhaust pipe. The refrigerant gas provides power for the refrigeration cycle, thereby achieving compression condensation expa...
