The refrigeration circuit 230 is exemplified below.

Illustratively, as shown in fig. 1 and 3, the refrigeration circuit 230 further includes a first line 231, a first valve 232, a second line 233, a second valve 234, a throttle device 235 (hereinafter referred to as a first throttle device 235 for ease of distinction), and a first heat exchanger 236.

The first valve 232 is openably and closably disposed in the first pipeline 231, and the first valve 232 is used for controlling on/off of the first pipeline 231. The second pipe 233 and the first pipe 231 are connected in parallel between the refrigerant outlet of the refrigeration circuit 230 and the air inlet of the compressor unit 100, the second valve 234 is openably and closably arranged on the second pipe 233, and the second valve 234 is used for controlling the on-off of the second pipe 233. The first throttling device 235 is disposed in the second pipeline 233, the refrigerant inlet of the first heat exchanger 236 is communicated with the liquid outlet of the first throttling device 235, and the refrigerant outlet of the first heat exchanger 236 is communicated with the air inlet of the compressor unit 100.

In the present embodiment, the refrigeration device 250 and the first valve 232 are both disposed in the first pipeline 231, and the first pipeline 231 is communicated between the refrigerant outlet of the heating circuit 220 and the air inlet of the compressor unit 100. In this way, when the first valve 232 is opened, the first pipe 231 is turned on, and the refrigerant flowing out of the heating circuit 220 can flow into the refrigerating apparatus 250 through the first pipe 231 to supply cold to the refrigerating apparatus 250, thereby realizing refrigeration.

The second valve 234 and the first throttling device 235 are disposed in the second pipeline 233, the second pipeline 233 and the first pipeline 231 are connected in parallel between the refrigerant outlet of the refrigeration circuit 230 and the air inlet of the compressor unit 100, when the refrigeration equipment 250 is not required for refrigeration, the first valve 232 can be closed, the second valve 234 is opened, and the second pipeline 233 is enabled to conduct the refrigerant flowing out of the heating circuit 220 and can enter the first throttling device 235 through the second pipeline 233.

The refrigerant flows into the first heat exchanger 236 after being depressurized in the first throttling device 235, and absorbs heat in the first heat exchanger 236 to release redundant cold energy, so that the refrigerant can be changed into a low-temperature low-pressure gaseous refrigerant, and the compressor unit 100 can work normally when the refrigerant flows into the compressor unit 100. Thus, the user can select the first valve 232 to be opened or the second valve 234 to be opened according to the actual requirement, so that the refrigerating device 250 can be operated or closed, thereby meeting various requirements of the user.

Further, the refrigerant inlet of the first heat exchanger 236 is also in communication with the other end of the first pipe 231.

Since the heating circuit 220 and the cooling circuit 230 are in the same thermal management system in this embodiment, the power of the compressor unit 100 is constant, and thus the total amount of heat generated in the heating circuit 220 and the total amount of cold generated in the cooling circuit 230 should be the same. In this embodiment, the other end of the first pipeline 231 is communicated with the refrigerant inlet of the first heat exchanger 236, the refrigerant outlet of the first heat exchanger 236 is communicated with the air inlet of the compressor unit 100, and the first pipeline 231 is communicated with the compressor unit 100 through the first heat exchanger 236.

Further, as shown in fig. 3, in the case that the refrigeration circuit 230 includes a plurality of refrigeration apparatuses 250, the number of the first pipelines 231 is the same as and corresponds to the number of the refrigeration apparatuses 250, the plurality of first pipelines 231 are arranged in parallel, and a first valve 232 is disposed on one first pipeline 231.

In the case that the refrigeration circuit 230 includes a plurality of refrigeration devices 250, the refrigeration circuit 230 also includes a plurality of first pipes 231, and the plurality of first pipes 231 are disposed in parallel, and the number of first pipes 231 is the same as and in one-to-one correspondence with the number of refrigeration devices 250. In this way, the refrigerant flowing out of the heating circuit 220 can flow into the plurality of first pipelines 231 respectively, so as to release cold in the refrigerating devices 250 in each first pipeline 231, thereby meeting the refrigerating requirements of the plurality of refrigerating devices 250. Each first pipeline 231 is provided with a first valve 232, so that a user can control the operation of the refrigeration equipment 250 according to the opening and closing of the first valve 232, and when the first valve 232 is opened, a refrigerant enters the corresponding first pipeline 231 and the corresponding refrigeration equipment 250 operates; when the first valve 232 is closed, the corresponding first pipeline 231 is disconnected, and the corresponding refrigeration equipment 250 stops working, so as to meet different refrigeration demands of users and improve the use experience of the users.

The third valve 222 is openably and closably disposed in the third pipeline 221, and the third valve 222 is used for controlling the on/off of the third pipeline 221. The fourth pipeline 223 is connected in parallel with the third pipeline 221 and is arranged between the air outlet of the compressor unit 100 and the refrigerant inlet of the refrigeration circuit 230. The fourth valve 224 is openably and closably disposed in the fourth pipeline 223, and the fourth valve 224 is used for controlling the on/off of the fourth pipeline 223. The refrigerant inlet of the second heat exchanger 225 communicates with the fourth pipe 223, and the refrigerant outlet of the second heat exchanger 225 communicates with the air inlet of the compressor unit 100.

In this embodiment, the heating device 240 and the third valve 222 are both disposed in the third pipeline 221, and the third pipeline 221 is connected between the air outlet of the compressor unit 100 and the refrigerant inlet of the refrigeration circuit 230, so that when the third valve 222 is opened, the third pipeline 221 is turned on, and the refrigerant flowing out of the compressor unit 100 can flow out of the heating device 240 through the third pipeline 221 to provide heat for the heating device 240, thereby realizing heating.

The fourth valve 224 is disposed in the fourth pipeline 223, the fourth pipeline 223 and the third pipeline 221 are connected in parallel between the air outlet of the compressor unit 100 and the refrigerant inlet of the refrigeration circuit 230, when the heating device 240 is not needed for heating, the third valve 222 can be closed, the fourth valve 224 can be opened, and the fourth pipeline 223 is connected to the refrigerant flowing out of the compressor unit 100 and can enter the second heat exchanger 225 through the fourth pipeline 223. The refrigerant releases excessive heat in the second heat exchanger 225 to be changed into a low-temperature low-pressure liquid refrigerant, thereby ensuring that the refrigerant can normally operate in the refrigeration equipment 250 when the refrigerant flows into the refrigeration circuit 230. Thus, the user can select the first valve 232 to be opened or the second valve 234 to be opened according to the actual requirement, so that the refrigerating device 250 can be operated or closed, thereby meeting various requirements of the user.

Optionally, the second heat exchanger 225 is located outdoors.

In this embodiment, the second heat exchanger 225 is configured to release heat that is unnecessary for the user in the heat management system, that is, excessive heat, and the second heat exchanger is disposed outdoors, so that the excessive heat released by the second heat exchanger 225 can be reduced to affect the indoor environment of the user, and thus the comfort and the experience of the user are improved.

Alternatively, the heating apparatus 240 includes a condenser, and the heating apparatus 240 may be a water heater, a heating system, a heating air conditioner, or the like.

Further, the refrigerant inlet of the second heat exchanger 225 is also communicated with the other end of the third pipe 221.

Since the heating circuit 220 and the cooling circuit 230 are in the same thermal management system in this embodiment, the power of the compressor unit 100 is constant, and thus the total amount of heat generated in the heating circuit 220 and the total amount of cold generated in the cooling circuit 230 should be the same. In this embodiment, the other end of the third pipeline 221 is connected to the refrigerant inlet of the second heat exchanger 225, the refrigerant outlet of the second heat exchanger 225 is connected to the refrigerant inlet of the refrigeration circuit 230, and the third pipeline 221 is connected to the refrigeration circuit 230 through the second heat exchanger 225. In this way, when the third pipe 221 is turned on, the refrigerant flowing out of the third pipe 221 can flow into the second heat exchanger 225, and when there is excessive heat in the refrigerant flowing out of the second pipe 233, the refrigerant releases heat again in the second heat exchanger 225, so that the excessive heat in the refrigerant flowing out of the third pipe 221 is released, and the occurrence of the condition that the refrigerant with higher heat cannot absorb much heat in the refrigeration circuit 230 is reduced, thereby ensuring that the refrigerant can normally operate in the refrigeration circuit 230.

Further, as shown in fig. 3, in the case that the heating circuit 220 includes a plurality of heating devices 240, the number of third pipelines 221 is the same as and corresponds to the number of the heating devices 240, the plurality of third pipelines 221 are arranged in parallel, and a third valve 222 is disposed on one third pipeline 221.

In each user home, a plurality of heating devices 240 may need to be operated simultaneously, for example, in winter, the water heater and the heating air conditioner need to be turned on simultaneously, and the plurality of heating devices 240 are all disposed in the heating circuit 220. In the case that the heating circuit 220 includes a plurality of heating devices 240, the heating circuit 220 also includes a plurality of third pipelines 221, and the plurality of third pipelines 221 are disposed in parallel, where the number of third pipelines 221 is the same as and corresponds to the number of heating devices 240 one by one. In this way, the refrigerant flowing out of the heating circuit 220 can flow into the plurality of third pipelines 221 respectively, so as to release heat in the heating devices 240 in each third pipeline 221, thereby meeting the heating requirements of the plurality of heating devices 240. Each third pipeline 221 is provided with a third valve 222, so that a user can control the operation of the heating equipment 240 according to the opening and closing of the third valve 222, and when the third valve 222 is opened, a refrigerant enters the corresponding third pipeline 221, and the corresponding heating equipment 240 operates; when the third valve 222 is closed, the corresponding third pipeline 221 is disconnected, and the corresponding heating device 240 stops working, so as to meet different heating requirements of users and improve the use experience of the users.

In this embodiment, the inner side wall of the third heat exchange tube encloses a first refrigerant space, the first refrigerant space is used for the refrigerant flowing in the second heat exchanger 225, and the temperature of the refrigerant in the first refrigerant space is higher. The fourth heat exchange tube is sleeved on the outer side of the third heat exchange tube, the outer side wall of the third heat exchange tube and the inner side wall of the fourth heat exchange tube enclose a second refrigerant space, the second refrigerant space is used for refrigerant flow of the first heat exchanger 236, and the temperature of the refrigerant in the second refrigerant space is lower. In this way, the refrigerant in the first refrigerant space and the refrigerant in the second refrigerant space can exchange heat only through the pipe wall of the third heat exchange pipe, so that the heat exchange efficiency of the refrigerant in the first refrigerant space and the refrigerant in the second refrigerant space is improved, and the heat exchange efficiency between the second heat exchanger 225 and the first heat exchanger 236 is improved.
