[0035] In one embodiment, if Figure 1 As shown, the heat exchange module 100 includes a compressor 120, a first heat exchanger 110, and a second heat exchanger 130. The first heat exchanger 110 is connected to the inlet end of the compressor 120 and the inlet end of the cooling module 200, and the second heat exchanger 130 is connected to the outlet end of the compressor 120, the inlet end of the first heat exchanger 110, and the inlet end of the heating module 300. Specifically, the refrigerant in the first heat exchanger 110 evaporates from liquid to gas, absorbs heat, and thus refrigerates.

[0036] The refrigeration module 200 includes at least one cold storage tank 210 and at least one refrigeration device 220. The cold storage tank 210 is connected to the first heat exchanger 110. The first medium and the second medium are exchanged inside the first heat exchanger 110. The first medium after heat exchange is transferred to the cold storage tank 210 through the copper tube 520. The second medium and the third medium are heat exchanged inside the cold storage tank 210. The cold storage tank 210 transfers the third medium to the refrigeration device 220 through the atmospheric pressure pipe 530.

[0037] Specifically, a cold storage tank 210 is provided between the refrigeration device 220 and the heat exchange module 100 of the present invention. The first medium exchanges heat with the second medium in the first heat exchanger 110, and the second medium is then centrally output to the cold storage tank 210 for heat exchange. The first heat exchanger 110 can be connected to multiple cold storage tanks 210. In the cold storage tank 210, the second medium and the third medium exchange heat. The cold storage tank 210 can transmit the refrigerated third medium to the refrigeration device 220 through the normal pressure pipe 530, and one cold storage tank 210 can be connected to multiple refrigeration devices 220 through the normal pressure pipe 530.

In this case, the second medium is selected based on the type of refrigeration device 220. It can be a sub-zero refrigerant or a sub-zero refrigerant such as water. Typically, the second medium is not fully utilized after passing through the refrigeration terminal 400, especially sub-zero refrigerants. In this case, the refrigerant output from the refrigeration terminal 400 can be input into the refrigeration module 200, where it continues to exchange heat with the third medium in the cold storage tank 210, thereby fully utilizing the refrigerant.

[0040] Specifically, the second medium output from the first heat exchanger 110 is fed into the spiral tube 500 of the first tank body through the first through hole 211. The third medium is contained in the cold storage tank 210. After heat exchange between the second and third media, the second medium is then output from the second through hole 212 through the copper tube 520 outside the cold storage tank 210 to the first heat exchanger 110. The used second medium is then processed and reused for cooling. Preferably, the spiral tube 500, due to its spiral arrangement within the tank body, provides a larger contact area with the second medium, thereby improving heat exchange efficiency.

[0041] In a preferred embodiment, the spiral tube 500 is connected to the first through hole 211 to increase the heat exchange area, and the straight tube 510 is connected to the second through hole 212 to speed up the backflow of the second medium.

[0043] Specifically, the first heat dissipation fins and the first air supply structure are installed on the first body. The first body is the outer shell of the refrigeration equipment 220. According to the type of the refrigeration equipment 220, the third medium after heat exchange with the second medium output by the first heat exchanger 110 is output to the first heat dissipation fins of the refrigeration equipment 220; the first air supply structure is installed relative to the first heat dissipation fins, and the air is blown out by the first air supply structure after being cooled by the first heat dissipation fins.

[0044] In this embodiment, the compressor 120 increases the pressure and temperature of the used first medium, and the second heat exchanger 130 generates a large amount of heat in the process of cooling the first medium after the temperature and pressure are increased. The refrigerant is still in a relatively high temperature state, and some heat is not used, resulting in significant energy waste in the system as a whole.

[0045] In this regard, the present invention adds a heating module 300, which includes at least one heat storage tank 310 and at least one heat dissipation device 320. The heat storage tank 310 is connected to the second heat exchanger 130. The first medium and the second medium are exchanged inside the second heat exchanger 130, and the medium after heat exchange is transferred to the heat storage tank 310. The second medium and the third medium are heat exchanged inside the heat storage tank 310. The heat storage tank 310 transfers the third medium to the heat dissipation device 320 through the atmospheric pressure pipe 530.

[0046] Specifically, the heat storage tank 310 and the second heat exchanger 130 of the heat exchange module 100 are connected via a copper tube 520. After heat exchange within the second heat exchanger 130, the second medium output by the second heat exchanger 130 reaches a higher temperature. This second medium then exchanges heat with the third medium in the heat storage tank 310, transferring heat to the third medium, heating it. The third medium is then transferred to the heat dissipation device 320 for use by the heat dissipation device 320, which can be a household water heater or other heat dissipation device. By adding the heating module 300, the energy of the atmospheric pressure heat exchange system is fully utilized, heat loss is reduced, and the environment is protected. Furthermore, the heat storage tank 310 and the heat dissipation device 320 are connected via an atmospheric pressure tube 530.

[0048] Specifically, the second medium output from the second heat exchanger 130 is fed into the spiral tube 500 of the second tank body through the fifth through-hole. The heat storage tank 310 is filled with the third medium. After the second and third media exchange heat, the second medium is then output from the fifth through-hole through the copper tube 520 outside the heat storage tank 310 to the first heat exchanger 110, where it continues to cool. This achieves a cooling and heating cycle for the second medium throughout the entire system. Preferably, the spiral tube 500, due to its spiral arrangement within the tank body, provides a larger contact area with the second medium, thereby improving heat exchange efficiency.

The cold storage tank 210 can transmit the refrigerated third medium to the refrigeration device 220 through the normal pressure pipe 530, and one cold storage tank 210 can be connected to multiple refrigeration devices 220 through the normal pressure pipe 530. By adding the cold storage tank 210, the present invention not only reduces the use of copper tubes 520 in the heat exchange system, but also allows multiple refrigeration devices 220 to be connected externally through the cold storage tank 210, thereby ensuring the safety of the system while reducing the cost of the system.

In this case, the second medium is selected based on the type of refrigeration equipment 220. It can be a subzero refrigerant or a superzero refrigerant such as water.
