Problems solved by technology

[0002] In supermarkets, fresh markets and other places, due to the need to keep products fresh, refrigerators or freezers must be continuously refrigerated. At the same time, it is necessary to keep the humidity of the indoor environment stable to avoid indoor condensation and frost due to low temperature. ;In the existing supermarkets, the freezer and the dehumidifier are independent equipment. The freezer adopts the traditional refrigeration method of evaporative condensation cycle, and the heat in the cooling process is directly dissipated. Due to the continuous cooling, the energy consumption of the freezer and the dehumidifier is very huge. , and caused high maintenance costs and a large amount of refrigerant consumption
