This technology is similar to the refrigeration method of traditional household refrigerators. It uses compressor power to achieve a fast and strong refrigeration effect, which can reach a temperature of -18°C, so it can achieve the refrigeration function. In commonly used air conditioners or refrigerators, a compressor-evaporator-condenser is used to evaporate the refrigerant, and absorb heat during the evaporation process to achieve the refrigeration effect. However, during the refrigeration process, the refrigerant evaporates into high-pressure steam, so high-pressure resistant pipes (such as copper pipes) are required to transport gaseous refrigerants. The use of high-pressure pipelines, especially copper pipes, is expensive, and once the pipeline is damaged, it is easy to cause damage to the surrounding area. High-pressure pipelines are not easy to bend, and it is difficult to lay out the pipelines. Summary of the invention

[0021] 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 transmitted 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 transmits the third medium to the refrigeration device 220 through the atmospheric pressure pipe 530.

[0022] Specifically, a cold storage tank 210 is provided between the refrigeration equipment 220 and the heat exchange module 100 of the present invention, the first medium performs heat exchange with the second medium in the first heat exchanger 110, and then the second medium is centrally output to the cold storage tank 210 for heat exchange, the first heat exchanger 110 can be connected to a plurality of cold storage tanks 210, in which the second medium and the third medium perform heat exchange, the cold storage tank 210 can transmit the refrigerated third medium to the refrigeration equipment 220 through the normal pressure pipe 530, and one cold storage tank 210 can be connected to a plurality of refrigeration equipment 220 through the normal pressure pipe 530.

Specifically, the refrigeration terminal 400 is a device that needs to be refrigerated below zero degrees, such as a freezer or other refrigeration terminal 400 devices. At this time, the second medium is selected according to the type of the refrigeration device 220. A sub-zero refrigerant or a refrigerant above zero such as water can be selected. Usually, the second medium is not fully utilized when passing through the refrigeration terminal 400, especially the sub-zero refrigerant. At this time, the refrigerant output from the refrigeration terminal 400 can be input into the refrigeration module 200, and heat exchange with the third medium continues in the cold storage tank 210, so as to make full use of the refrigerant.

[0025] Specifically, the second medium output by the first heat exchanger 110 is input into the spiral tube 500 of the first tank body from the first through hole 211, and the third medium is contained in the cold storage tank 210. After the second medium and the third medium perform heat exchange, the second medium is output to the first heat exchanger 110 from the second through hole 212 through the copper tube 520 outside the cold storage tank 210, and the used second medium is processed so that it can be used again for refrigeration. Preferably, the spiral tube 500 has a larger contact area with the second medium because it is spirally arranged in the tank body, which can improve the efficiency of heat exchange.

[0026] 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 reflux speed of the second medium.

[0027] In one embodiment, the refrigeration equipment 220 includes a first body, a first heat dissipation fin and a first air supply structure, and the first heat dissipation fin and the first air supply structure are installed on the first body; the cold storage tank 210 is provided with a third through hole 213 and a fourth through hole 214, and the normal pressure pipe 530 connects the outlet end of the cold storage tank 210 and the inlet end of the first heat dissipation fin through the third through hole 213 to transmit the third medium into the first heat dissipation fin; the normal pressure pipe 530 connects the outlet end of the first heat dissipation fin and the inlet end of the cold storage tank 210 through the fourth through hole 214 to output the used third medium to the cold storage tank 210 for re-heat exchange.

[0028] Specifically, the first heat dissipation fins and the first air supply structure are installed on the first body, and the first body is the external shell of the refrigeration device 220.

[0029] In this embodiment, the compressor 120 increases the pressure and temperature of the first medium after use, 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.

[0030] 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.

For example, the heat dissipation device 320 can be a household water heater or other heat dissipation device. By adding the heating module 300, the energy of the normal pressure heat exchange system is fully utilized, heat loss is reduced, and the environment is protected.

The refrigerant in the first heat exchanger 110 is vaporized from liquid to gas, absorbs heat and performs refrigeration, and then the refrigerated refrigerant is transmitted to the compressor 120, and the compressor 120 processes the refrigerant into a high-temperature and high-pressure refrigerant, and then the high-temperature and high-pressure refrigerant is input into the second heat exchanger 130 for condensation, and the condensed refrigerant is input into the first heat exchanger 110 through the connection end of the second heat exchanger 130 and the first heat exchanger 110 for refrigeration.

[0046] In one embodiment, if Fig.11 As shown, S300 includes the following steps: S310, the compressor of the heat exchange module 100 transmits the first medium after heat exchange to the second heat exchanger 130 through the copper tube 520; In the heat storage tank 310 of the heating module 300; S320, exchanging heat between the first medium and the second medium in the second heat exchanger 130; S330, transmitting the second medium after heat exchange to the heat storage tank 310 of the heating module 300, and the second medium performs heat exchange with the third medium in the heat storage pipe; S340, transporting the third medium in the heat storage tank 310 that has undergone heat exchange to the outside for use by the heat dissipation device 320.

[0047] S400 specifically involves the second medium being transferred from the heating module 300 to the second heat exchanger 130 of the heat exchange module 100 for re-heat exchange.

[0048] Specifically, the heat storage tank 310 and the second heat exchanger 130 of the heat exchange module 100 are connected by a copper tube 520. After the second medium output by the second heat exchanger 130 undergoes heat exchange inside the second heat exchanger 130, it has a higher temperature and exchanges heat with the third medium in the heat storage tank 310, transferring heat to the third medium, heating the third medium, and then transferring the third medium to the heat dissipation device 320 for use by the heat dissipation device 320. For example, the heat dissipation device 320 can be a household water heater or other heat dissipation device. By adding the heating module 300, the energy of the normal pressure heat exchange system is fully utilized, heat loss is reduced, and the environment is protected. At the same time, the heat storage tank 310 and the heat dissipation device 320 are connected by a normal pressure pipe 530, and multiple heat storage tanks 310 can be set, and one heat storage tank 310 can be connected to multiple heat dissipation devices 320, which is specifically determined according to the heat storage amount of the heat storage tank 310 and the heat dissipation device 320.
