The energy storage liquid can be a mixture of high molecular organic materials, such as a mixture of sodium polyacrylate, sodium carboxymethyl cellulose and the like, and has higher cold capacity and can store more cold.

Specifically, in one embodiment, as shown in fig. 1, the heat exchanging device 110 is disposed adjacent to the compressor 101 and in contact with the compressor 101, and the energy storage fluid can transfer cold energy to the compressor 101 by heat conduction, so as to lower the temperature of the compressor 101, and achieve the effect of dissipating heat from the compressor 101.

That is, the heat exchange device 110 arranged as above can cool down the compressor 101 and the press cabin 120 by conduction and convection.

In another embodiment, as shown in fig. 4, the heat exchanging device 110 may be disposed adjacent to the condenser 122, and the heat exchanging device 110 may be formed with a second vent hole 113 to enable hot air in the compressor compartment 120 to exchange heat with cold in the heat exchanging device 110 under the driving of the heat dissipation fan 108, so as to accelerate heat dissipation of the compressor 101 and the condenser 122.

The heat dissipation fan 108 is configured to draw ambient air from a second heat dissipation opening 120b on a side adjacent to the condenser 122, cause the ambient air to flow through the condenser 122, the heat exchange device 110, the compressor 101, and flow out of the press bin 120 from another second heat dissipation opening 120 b. In this way, the cold stored in the energy storage liquid in the heat exchanger 110 is used to sequentially dissipate heat from the condenser 122 and the compressor 101 by the convection method, thereby reducing the temperatures of the condenser 122 and the compressor 101.

As described above, in the present embodiment, the heat exchange device 110 is disposed at a specific position in the press cabin 120 by using the cold energy released by the heat exchanger 111 during the defrosting process accumulated by the energy storage liquid, so as to effectively reduce the condensation temperature, increase the cooling capacity of the refrigeration system, reduce the on-time rate of the compressor 101, and further reduce the energy consumption.
