It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, device, product or appliance that includes a series of steps or modules is not necessarily limited to those steps or modules that are clearly listed, but may include other steps or modules that are not clearly listed or inherent to these processes, methods, products or appliances.

[0034] In the prior art, in winter, the room where the refrigeration device and the air conditioner are located are not necessarily the same room. On the one hand, users will turn on the air conditioner to obtain heat, and on the other hand, the heat released by the refrigeration device is wasted. Based on this, the present application proposes an integrated system of air conditioning and refrigeration device, which utilizes the heat released by the refrigeration device to provide the heating effect of air conditioning, so as to improve user experience and save electricity.

[0035] Please refer to the figure. The present application proposes an integrated air conditioning and refrigeration device system, including: an air conditioning and a refrigeration device; the air conditioning includes a first compressor 1, an indoor unit 2, an outdoor unit 3 and a first throttling device 41 arranged between the indoor unit 2 and the outdoor unit 3; the refrigeration device can release heat through the indoor unit 2.

[0036] Specifically, the first compressor 1, the indoor unit 2 and the outdoor unit 3 of the air conditioner are connected by pipes to form a cooling and heating circuit. The specific connection method can adopt the connection method in the prior art, such as Figure 1 As shown, the exhaust port of the first compressor 1 is connected to the four-way valve, and the four-way valve is also connected to the air intake port of the first compressor, the indoor unit 2 and the outdoor unit 3 through pipelines, and the indoor unit 2 and the outdoor unit 3 are connected through pipelines. The connection relationship between the first compressor 1, the indoor unit 2, the outdoor unit 3 and the four-way valve can adopt the existing technology. Refrigeration devices, such as refrigerators, generate heat during use. In order to make full use of this heat, improve the user experience and save electricity, the refrigeration device can release heat through the indoor unit, thereby improving the heating effect of the air conditioner in winter and realizing energy recovery and reuse.

[0037] Preferably, in some optional embodiments, the refrigeration device can also release heat through the outdoor unit 3. In this embodiment, the refrigeration device can also release heat through the outdoor unit. In the prior art, after the air conditioner is turned on in winter, the outdoor unit absorbs ambient heat as an evaporator, resulting in a low temperature of the outdoor unit and easy frost, causing damage to the outdoor unit. The refrigeration device of the present application can also release heat through the outdoor unit 3, so the heat released by the refrigeration device can increase the temperature of the outdoor unit and prevent frost on the outdoor unit.

[0038] Preferably, if Figure 1 As shown, the refrigeration device includes a second compressor 5 and an evaporator 6; the air intake port of the second compressor 5 is connected to the outlet of the evaporator 6, one end of the first pipeline 71 is connected to the exhaust port of the second compressor 5, the other end of the first pipeline 71 is connected to the first heat exchange pipe 81, the other end of the first heat exchange pipe 81 is connected to one end of the second pipeline 72, the other end of the second pipeline 72 is connected to the inlet of the evaporator 6, the first pipeline 71 or the second pipeline 72 is provided with a second throttling device 42, and the first heat exchange pipe 81 and the second heat exchange pipe 82 of the indoor unit 2 are arranged side by side.

[0039] Specifically, during use, the refrigeration device is turned on, and the exhaust port of the second compressor 5 discharges high-temperature and high-pressure refrigerant. The refrigerant can reach the first heat exchange tube 81 through the first pipeline 71. The first heat exchange tube 81 can be located inside the indoor unit, release heat at the indoor unit, and then return to the evaporator 6 through the second pipeline 72 to evaporate and absorb heat. The refrigeration device can be a refrigerator or a freezer. The present application improves the heating effect of the air conditioner in winter by arranging a refrigeration device to release heat in the indoor unit.

[0040] Preferably, in some optional embodiments, it also includes: a third pipeline 73, a third heat exchange pipe 83 and a fourth pipeline 74; one end of the third pipeline 73 is connected to the exhaust port of the second compressor 5, and the other end of the third pipeline 73 is connected to one end of the third heat exchange pipe 83; the other end of the third heat exchange pipe 83 is connected to one end of the fourth pipeline 74, and the other end of the fourth pipeline 74 is connected to the second pipeline 72; the third heat exchange pipe 83 and the fourth heat exchange pipe 84 of the outdoor unit 3 are arranged side by side.

[0041] For details, please refer to the attached Figure 1In this embodiment, the high-temperature and high-pressure refrigerant discharged from the exhaust port of the second compressor 5 can be heat exchanged at the outdoor unit and / or the indoor unit. Specifically, a control valve can be set on the first pipeline 71 or the third pipeline 73 to control the flow direction of the refrigerant. In winter, when the outdoor unit is frosted or about to be frosted, the refrigerant in the pipeline of the refrigeration device is controlled to release heat at the outdoor unit to prevent the outdoor unit from frosting. The heat exchanger of the outdoor unit can be used to absorb the heat of the refrigerant of the refrigeration device to further reduce the temperature of the refrigerant, thereby improving the refrigeration effect of the refrigeration device. It should be noted that when the fourth pipeline is included, the second throttling device 42 is located on the second pipeline 72 and is located between the inlet of the evaporator 6 and one end of the fourth pipeline connected to the second pipeline.

[0042] Preferably, in some optional embodiments, it also includes: a subcooler 9; the subcooler 9 includes a first port and a second port connected to each other, and a third port and a fourth port connected to each other; one end of the fifth pipeline 75 is connected to the first port, and the other end of the fifth pipeline 75 is connected to the pipeline between the outdoor unit 3 and the indoor unit 2, and the fifth pipeline 75 is provided with a third throttling device 43; one end of the sixth pipeline 76 is connected to the second port, and the other end of the sixth pipeline 76 is connected to the air inlet of the first compressor 1; one end of the seventh pipeline 77 is connected to the third port, and the other end of the seventh pipeline 77 is connected to the second pipeline 72; one end of the eighth pipeline 78 is connected to the fourth port, and the other end of the eighth pipeline 78 is connected to the second pipeline 72 shown.

[0043] Specifically, the function of the subcooler 9 is to use the refrigerant of the air conditioner to reduce the temperature of the refrigerant returning to the suction port of the second compressor 5, so as to improve the refrigeration effect of the refrigeration device. Figure 1When the air conditioner is in cooling mode, the high-temperature and high-pressure refrigerant discharged from the first compressor 1 releases heat through the outdoor unit and becomes a low-temperature and high-pressure refrigerant. Then, a part of the refrigerant of the air conditioner flows into the first port of the subcooler from the fifth pipeline 75, and then flows back to the first compressor 1 from the second port. At this time, the refrigerant of the refrigeration device on the second pipeline can flow into the third port of the subcooler 9 from the seventh pipeline, and then flow out from the fourth port through the eighth pipeline 78. Since the third throttling device 43 is provided on the fifth pipeline 75, the refrigerant of the air conditioner flowing from the fifth pipeline 75 into the first port will evaporate and absorb heat, thereby reducing the temperature of the refrigerant of the refrigeration device flowing into the subcooler through the seventh pipeline 77. The refrigerant with a reduced temperature can absorb more heat at the evaporator 6, thereby improving the refrigeration effect of the refrigeration device. Another part of the refrigerant of the air conditioner returns to the first compressor 1 through the indoor unit 2 for heat exchange. When the air conditioner is in heating mode, the high-temperature and high-pressure refrigerant discharged from the first compressor 1 releases heat through the indoor unit, and then flows into the first port from the fifth pipeline 75 to absorb the heat of the refrigerant of the refrigeration device. That is, whether the air conditioner is in cooling mode or heating mode, the subcooler 9 can be used to enhance the refrigeration capacity of the refrigeration device. Optionally, a temperature detection device is provided at the air intake of the first compressor to detect the temperature of the refrigerant flowing into the first compressor and adjust the opening of the third throttling device according to the temperature of the refrigerant.

[0044] Preferably, in some optional embodiments, it further comprises: a ninth pipeline 79; one end of the ninth pipeline 79 is connected to the pipeline between the other end of the fifth pipeline 75 and the third throttling device 43; the other end of the ninth pipeline 79 is connected to the pipeline between the other end of the fifth pipeline 75 and the indoor unit 2; the first throttling device 41 is arranged between the other end of the fifth pipeline 75 and the other end of the ninth pipeline 79. Specifically, the ninth pipeline 79 is arranged to adjust the amount of refrigerant flowing into the subcooler. The first throttling device 41 can be an expansion valve or a capillary tube.

[0045] Preferably, in some optional embodiments, a first control valve 91 is provided on the fifth pipeline 75; and / or a first one-way valve 11 is provided on the fifth pipeline 75, and the first one-way valve 11 allows the refrigerant to flow from the other end of the fifth pipeline to the first port; and / or a third control valve 93 is provided on the seventh pipeline 77; and / or a fourth control valve 94 is provided on the eighth pipeline 78; and / or a fifth control valve 95 is provided on the second pipeline 72, and the fifth control valve 95 is located between the other end of the seventh pipeline 77 and the other end of the eighth pipeline 78.

[0046] Specifically, the first control valve 91 can be provided to adjust the amount of refrigerant flowing into the subcooler 9, and the first check valve 11 can be provided to prevent the refrigerant from flowing in reverse, thereby ensuring the safe and normal operation of the subcooler and the first compressor. The third control valve 93, the fourth control valve 94 and the fifth control valve 95 can be provided to control the amount of refrigerant flowing into the subcooler 9 of the refrigeration device, thereby ensuring that the refrigeration effect of the refrigeration device is controllable.

[0047] Preferably, in some optional embodiments, a second control valve 92 is provided on the ninth pipeline 79, and / or a second check valve 12 is provided on the ninth pipeline 79. The second check valve 12 allows the refrigerant to flow from the other end of the ninth pipeline to the end connected to the fifth pipeline 75. The second check valve 12 is provided to prevent the refrigerant in the air conditioner from flowing in the reverse direction.

[0048] Preferably, in some optional embodiments, it further includes: a liquid reservoir 10, and the liquid reservoir 10 is arranged on the second pipeline 72. Preferably, a sixth control valve 96 is arranged on the third pipeline 73, and / or a seventh control valve 97 is arranged on the fourth pipeline 74. By setting the sixth control valve 96 and the seventh control valve 97, the refrigerant can be controlled to selectively release heat in the indoor unit and / or the outdoor unit to meet the different needs of users. Optionally, a gas-liquid separator is arranged between the evaporator 6 and the second compressor 5 to prevent liquid hammer problems. Optionally, an eighth control valve 98 is arranged on the first pipeline 71 to control the flow rate of the refrigerant.

[0049] In the present application, both the indoor unit and the outdoor unit can simultaneously exchange heat for the air conditioner and the refrigeration device, and can be used to recover part of the condensation heat of the refrigeration device in winter to prevent the outdoor unit of the air conditioner from frosting, or to improve the heating effect of the indoor air conditioner. In the present application, a supercooler is added, and the air conditioning system is used to supercool the refrigerant of the refrigeration device, thereby improving the efficiency of the refrigeration device and reducing power consumption. In the present application, the two condensers (the second heat exchange tube and the third heat exchange tube) of the refrigeration device can be integrated with the heat exchanger of the indoor unit and the heat exchanger of the outdoor unit of the air conditioner, respectively, so as to achieve the effect of heat recovery and anti-frost.

[0050] The following Figure 1 The structure shown illustrates the working of the integrated air conditioning and refrigeration system in this application.

[0051] In summer, the first compressor 1 compresses the refrigerant into a high-temperature and high-pressure gaseous refrigerant, which enters the outdoor unit 3 through a four-way reversing valve for condensation; the condensed high-pressure liquid refrigerant enters the indoor unit 2 through the first throttling device 41, exchanges heat with the indoor environment, and cools the room; the other path passes through the fifth pipeline 75 and the third throttling device 43, and then enters the subcooler 9 after throttling and reducing the pressure; the two paths of refrigerant absorb heat and become gaseous refrigerant and merge into the first compressor 1, completing the air conditioning refrigeration cycle. At the same time, the second compressor 5 compresses the refrigerant into a high-temperature and high-pressure gaseous refrigerant, enters the outdoor unit 3 and passes through the liquid storage device 10, and then enters the subcooler 9 for supercooling. The supercooled liquid refrigerant passes through the second throttling device 42, and then enters the evaporator 6 for cooling after throttling and reducing the pressure, and finally enters the second compressor through the gas-liquid separator.

[0052] In winter, the first compressor 1 compresses the refrigerant into a high-temperature and high-pressure gaseous refrigerant, which enters the indoor unit 2 through the four-way reversing valve, exchanges heat with the indoor environment, and heats up the room; the high-pressure liquid refrigerant after heat exchange enters the outdoor unit 3 through the first throttling device 41 for evaporation, and enters the subcooler 9 after throttling and reducing the pressure through the third throttling device 43; the two refrigerants absorb heat and become gaseous refrigerants and merge into the first compressor 1, completing the air conditioning heating cycle. At the same time, the second compressor 5 compresses the refrigerant into a high-temperature and high-pressure gaseous refrigerant and divides it into two streams, one entering the outdoor unit 3 and the other entering the indoor unit 2, and then the two refrigerants are mixed and enter the liquid storage tank 10, and then enter the subcooler 9 for supercooling, and the supercooled liquid refrigerant enters the evaporator 6 for cooling after throttling and reducing the pressure through the second throttling device 42, and finally enters the second compressor 5 through the gas-liquid separator.
