[0034] See Figure 1 , in the first aspect of the present utility model, the compressor 30, the common heat exchanger 40, the throttling device 50, and the branch switching device 60 are sequentially connected in a cycle through pipelines, a heat exchange working medium is provided in the pipelines, and the heat exchange working medium includes fluoride refrigerants (such as Freon) and hydrocarbon refrigerants (such as propane and isobutane, etc.). In the present utility model, the pipelines include a first pipeline 110 for connecting the compressor 30 and the branch switching device 60, a second pipeline 120 for connecting the compressor 30 and the common heat exchanger 40, a third pipeline 130 for connecting the throttling device 50 and the common heat exchanger 40, and a fourth pipeline 140 for connecting the branch switching device 60 and the throttling device 50.
[0035] In the first aspect of the present utility model, there are two connection methods for the pipeline, and the two connection methods respectively enable the heat exchange system to form a refrigeration cycle and a heating cycle. In the connection method of the refrigeration cycle, during refrigeration cycle, the common heat exchanger 40 serves as a condenser, and the branch heat exchanger 100 serves as an evaporator; the first end of the first pipeline 110 is connected to the inlet of the compressor 30, and the second end of the first pipeline 110 is connected to the first circulation pipeline interface 70 of the branch switching device 60; the first end of the second pipeline 120 is connected to the outlet of the compressor 30, and the second end of the second pipeline 120 is connected to the inlet of the common heat exchanger 40; the first end of the third pipeline 130 is connected to the outlet of the common heat exchanger 40, and the second end of the third pipeline 130 is connected to the inlet of the throttling device 50; the first end of the fourth pipeline 140 is connected to the outlet of the throttling device 50, and the second end of the fourth pipeline 140 is connected to the second circulation pipeline interface 80 of the branch switching device 60; the pipeline flow direction of the refrigeration cycle is the compressor 30, the common heat exchanger 40, the throttling device 50, the branch switching device 60, the branch heat exchanger 100, the branch switching device, and the compressor 30.
[0036] In the connection method of the heating cycle, during heating cycle, the common heat exchanger 40 serves as an evaporator, and the branch heat exchanger 100 serves as a condenser; the difference between the connection method of the heating cycle and the refrigeration cycle is that the connection methods of the first pipeline 110 and the second pipeline 120 to the compressor 30 are changed. The first end of the first pipeline 110 is connected to the outlet of the compressor 30, and the first end of the second pipeline 120 is connected to the inlet of the compressor 30. The connection methods of the remaining pipelines remain unchanged. Simply put, it is that the inlet and outlet directions of the compressor 30 are reversed. The pipeline flow direction of the refrigeration cycle is the compressor 30, the branch switching device 60, the branch heat exchanger 100, the branch switching device 60, the throttling device 50, the common heat exchanger 40, and the compressor 30.
[0037] In the first aspect of the present utility model, the branch switching device 60 is used to selectively connect at least one of the heat exchange branches 20. Specifically, the inventive point of the present utility model is to drive multiple heat exchange branches 20 by a set of the common compression assembly 10. Multiple heat exchange branches 20 can all be connected to the pipeline circulation of the common compression assembly 10, or some of the heat exchange branches 20 can be connected to the pipeline circulation of the common compression assembly 10.

Each heat exchange branch 20 is used to connect a pair of outlet pipes of the 2 groups of one-into-multiple-out pipes. Whether each heat exchange branch 20 is conducted can be controlled by the control valves on the pair of outlet pipes connected to the heat exchange branch 20.

The pipeline commutation device 150 includes a multi-way valve. Taking the multi-way valve as a four-way valve as an example, the four-way valve includes a first interface, a second interface, a third interface, and a fourth interface. When connecting the four-way valve, the first pipeline 110 is cut into a first section (connected to the compressor 30) and a second section (connected to the branch switching device 60), and the second pipeline 120 is cut into a third section (connected to the compressor 30) and a fourth section (connected to the common heat exchanger 40).

The first interface, the second interface, the third interface, and the fourth interface of the four-way valve are respectively connected to the cut-off ends of the first section, the second section, the third section, and the fourth section. In the present utility model, the function of the pipeline commutation device 150 is to form two pipeline flow directions for the first section, the second section, the third section, and the fourth section. The first is that the first section is connected to the second section and the third section is connected to the fourth section; the second is that the first section is connected to the fourth section and the third section is connected to the second section. In this embodiment of the present utility model, when the common compression assembly 10 changes the refrigeration cycle and the heating cycle, the pipeline can be switched through the pipeline commutation device 150, without the need for manual change of the connection mode between the compressor 30 and the first pipeline 110 and the second pipeline 120.
[0039] See Figure 3, in some alternative embodiments of the first aspect of the present utility model, a drying device 160 is provided on the third pipeline 130. In the present utility model, the function of the drying device 160 is to remove moisture and impurities in the heat exchange working medium in the common compression component pipeline, so as to ensure the purity of the heat exchange working medium, thereby obtaining a better heat exchange effect.
[0040] In addition, the second aspect of the present utility model further provides an integrated household appliance, including the heat exchange system described in any one of the first aspects of the present utility model.

[0048] <Embodiment 2>
[0049] See Figure 4 , on the basis of the heat exchange system described in Embodiment 1 of the present utility model, the integrated household appliance includes an ice making module 170, a chilled water module 180, a refrigerator module 190, an air conditioner indoor unit module 200, the hot water making module 210, and the water purification module 220.

[0050] The working principle of the heat exchange system in the integrated household appliance of the present utility model is as follows:
[0051] When the heat exchange branch 20 needs refrigeration, the working mode of the refrigeration process is that the low-temperature and low-pressure gaseous heat transfer working medium (refrigerant) enters the compressor 30 and becomes a high-temperature and high-pressure gas. The pipeline commutation device 150 switches to the refrigeration cycle flow path. The high-temperature and high-pressure gas enters the common heat exchanger 40 after passing through the pipeline commutation device 150 and becomes a low-temperature and high-pressure gas. Then it is throttled by the throttling device 50 and becomes a low-temperature and low-pressure liquid. After that, it enters the branch switching device 60 and evaporates into a low-temperature and low-pressure gas in the connected heat exchange branch 20. Finally, it flows back to the compressor 30 through the pipeline commutation device 150. During the refrigeration process, the common heat exchanger 40 serves as a condenser, and the branch heat exchanger 100 serves as an evaporator. The evaporator absorbs heat and generates cold.
[0052] When the heat exchange branch 20 needs heating, the working mode of the heating process is that the low-temperature and low-pressure gaseous heat transfer working medium (refrigerant) enters the compressor 30 and becomes a high-temperature and high-pressure gas. The pipeline commutation device 150 switches to the heating cycle flow path. The high-temperature and high-pressure gas enters the branch heat exchanger 100 of the heat exchange branch 20 connected to the branch switching device 60 after passing through the pipeline commutation device 150 and becomes a low-temperature and high-pressure gas. Then it is throttled by the throttling device 50 and becomes a low-temperature and low-pressure liquid. After that, it evaporates into a low-temperature and low-pressure gas in the common heat exchanger 40. Finally, it flows back to the compressor 30 through the pipeline commutation device 150. During the heating process, the common heat exchanger 40 serves as an evaporator, and the branch heat exchanger 100 serves as a condenser. The condenser dissipates heat and generates heat.
