The cold storage is one kind of refrigerating equipment, and its refrigeration area is much bigger than refrigerator, but they have the communicating refrigeration principle. The cold storage is refrigerated through the refrigerating system, low-pressure steam of a refrigerant in the refrigerating system is sucked by the compressor and is compressed into high-pressure steam which is then discharged to the condenser, and air in the cold storage continuously flows in a circulating mode to achieve the purpose of reducing the temperature. Outdoor air sucked by the axial flow fan flows through the condenser to take away heat emitted by the refrigerant, so that high-pressure refrigerant steam is condensed into high-pressure liquid. The high-pressure liquid passes through the filter and the throttling mechanism and then is sprayed into the evaporator, and is evaporated under corresponding low pressure to absorb the surrounding heat. Meanwhile, the cross-flow fan enables air to continuously enter fins of the evaporator for heat exchange, and the air which is cooled after heat release is sent into the refrigeration house. The heat released by the condenser of the refrigerating machine system is usually discharged to the ambient environment through the condenser fan, which is a huge waste for users who need to use heat sources, and meanwhile, certain waste heat pollution is brought to the ambient environment.
