For cold storage to be more energy efficient, this should be done!

For cold storage to be more energy efficient, this should be done! 1. The index for reducing the unit heat flow of the cold storage enclosure structure. In the design of the cold storage, the unit heat flow q of the outer wall of the low-temperature cold storage is generally about 11.63W. If the q can be reduced to 6.9W, for a 5000T~10000T class In low-temperature cold storage, it is estimated that the power cost can be reduced by about 10%.

Why the air-conditioning supplyreturn water temperature is 7℃-12℃

Reason analysis of 7 degree water supply: 　　 1. Starting from the refrigeration unit, the refrigerant evaporates in the evaporator and absorbs heat to cool the secondary side water. If the evaporation temperature is too low, it will cause frost on the surface of the evaporator and affect the heat transfer efficiency.
