[0060] This disclosure provides an indoor heat exchange component. For example... Figures 1 to 5 As shown.

[0061] The air conditioning indoor heat exchange assembly includes a first heat exchange module, which includes a first heat exchange element 41, a second heat exchange element 42, a first transfer valve 100, and an outlet sleeve assembly. The first heat exchange element 41 is provided with a first heat exchange outlet 412, and the second heat exchange element 42 is provided with a second heat exchange outlet 422. The first transfer valve 100 includes a first transfer inlet 11, a first transfer outlet 12, a second transfer inlet 13, and a second transfer outlet 14. The first transfer outlet 12 is connected to the first heat exchange outlet 412, and the second transfer outlet 14 is connected to the second heat exchange outlet 422. The outflow sleeve assembly includes a hot return water pipe 51 and a cold return water pipe 52. The hot return water pipe 51 is connected to the first transition inlet 11, and the cold return water pipe 52 is connected to the second transition inlet 13. The first transition valve 100 can selectively open the first transition inlet 11 and / or the second transition inlet 13. When the first transition inlet 11 is open and the second transition inlet 13 is blocked, both the first heat exchange outlet 412 and the second heat exchange outlet 422 are connected via the first transition inlet 11 to... The hot return water pipeline 51 is connected. When both the first transfer inlet 11 and the second transfer inlet 13 are open, the first heat exchange outlet 412 is connected to the hot return water pipeline 51 via the first transfer inlet 11, and the second heat exchange outlet 422 is connected to the cold return water pipeline 52 via the second transfer inlet 13. When the first transfer inlet 11 is blocked and the second transfer inlet 13 is open, both the first heat exchange outlet 412 and the second heat exchange outlet 422 are connected to the cold return water pipeline 52 via the second transfer inlet 13.

[0062] In the air conditioning indoor heat exchange component provided in this embodiment, a first transfer valve 100 is provided between the heat exchange outlet of the first heat exchange module and the outflow sleeve assembly. The first transfer valve 100 allows selective connection between the first heat exchange outlet 412 and the second heat exchange outlet 422 and the first transfer inlet 11 and / or the second transfer inlet 13. For example, when the air conditioning system is operating in cooling mode, the first transfer inlet 11 of the first transfer valve 100 can be blocked while the second transfer inlet 13 is open. At this time, the working fluid flowing out of the first heat exchange outlet 412 and the second heat exchange outlet 422 can flow into the cold return water pipe 52 through the second transfer inlet 13, enabling the air conditioning system to perform a cooling cycle. When the air conditioning system is operating in heating mode, the first transfer inlet 11 of the first transfer valve 100 can be opened while the second transfer inlet 13 is blocked. At this time, the working fluid flowing out of the first heat exchange outlet 412 and the second heat exchange outlet 422 can flow into the hot return water pipe 51 through the first transfer inlet 11, enabling the air conditioning system to perform a heating cycle. When the air conditioning system is running in reheat dehumidification mode, the first transfer inlet 11 and the second transfer inlet 13 of the controllable first transfer valve 100 are both open. At this time, the working fluid flowing out of the first heat exchange outlet 412 flows into the hot return water pipeline 51 through the first transfer inlet 11, and the working fluid flowing out of the second heat exchange outlet 422 flows into the cold return water pipeline 52 through the second transfer inlet 13, so that the air conditioning system performs reheat dehumidification cycle.

[0063] As can be seen, a first transfer valve 100 can achieve three different conduction modes, which greatly simplifies the complexity of the connection of valve pipe components of the air conditioning indoor heat exchange assembly.

[0064] Optionally, the outflow sleeve assembly includes a hot return water pipe 51 and a cold return water pipe 52, as well as an outer main pipe. The hot return water pipe 51 and the cold return water pipe 52 are disposed in the outer main pipe, which improves the installation stability and neatness of the outflow sleeve assembly.

[0065] Optionally, the working fluid flowing in the indoor heat exchange component of the air conditioner can be water or refrigerant, etc. The present disclosure does not limit the type of working fluid in the indoor heat exchange component of the air conditioner.

[0066] Optionally, the first heat exchange element 41 is further provided with a first heat exchange inlet 411, and the second heat exchange element 42 is further provided with a second heat exchange inlet 421. The first heat exchange module also includes a second transfer valve 200 and an inflow sleeve assembly. The second transfer valve 200 includes a third transfer inlet 2001, a third transfer outlet 2003, a fourth transfer inlet 2002, and a fourth transfer outlet 2004. The third transfer outlet 2003 is connected to the first heat exchange inlet 411, and the fourth transfer outlet 2004 is connected to the second heat exchange inlet 421. The outflow sleeve assembly includes a heating pipe 53 and a cooling pipe 54. The heating pipe 53 is connected to the third transfer inlet 2001, and the cooling pipe 54 is connected to the fourth transfer inlet 2002. The second transfer valve 200... The third transfer inlet 2001 and / or the fourth transfer inlet 2002 can be selectively connected. When the third transfer inlet 2001 is connected and the fourth transfer inlet 2002 is blocked, the heating pipeline 53 is connected to the first heat exchange inlet 411 and the second heat exchange inlet 421 via the third transfer inlet 2001. When both the third transfer inlet 2001 and the fourth transfer inlet 2002 are connected, the heating pipeline 53 is connected to the first heat exchange inlet 411 via the third transfer inlet 2001, and the cooling pipeline 54 is connected to the second heat exchange inlet 421 via the fourth transfer inlet 2002. When the third transfer inlet 2001 is blocked and the fourth transfer inlet 2002 is connected, the cooling pipeline 54 is connected to the first heat exchange inlet 411 and the second heat exchange inlet 421 via the fourth transfer inlet 2002.

[0067] A second transfer valve 200 is also provided between the heat exchange inlet of the first heat exchange module and the inflow sleeve assembly. The second transfer valve 200 allows selective connection between the first heat exchange inlet 411 and the second heat exchange inlet 421 and the third transfer inlet 2001 and / or the fourth transfer inlet 2002. For example, when the air conditioning system is in cooling mode, the third transfer inlet 2001 of the second transfer valve 200 can be blocked while the fourth transfer inlet 2002 is open. In this case, the cooling pipeline 54 is connected to the first heat exchange inlet 411 and the second heat exchange inlet 421 via the fourth transfer inlet 2002, enabling the air conditioning system to perform a cooling cycle. When the air conditioning system is in heating mode, the third transfer inlet 2001 of the second transfer valve 200 can be opened while the fourth transfer inlet 2002 is blocked. In this case, the heating pipeline 53 is connected to the first heat exchange inlet 411 and the second heat exchange inlet 421 via the third transfer inlet 2001, enabling the air conditioning system to perform a heating cycle. When the air conditioning system is in reheat dehumidification mode, the third transfer inlet 2001 and the fourth transfer inlet 2002 of the controllable transfer valve 200 are both open. At this time, the heating pipe 53 is connected to the first heat exchange inlet 411 through the third transfer inlet 2001, and the cooling pipe 54 is connected to the second heat exchange inlet 421 through the fourth transfer inlet 2002, so that the air conditioning system can perform reheat dehumidification cycle.

[0068] Similarly, the inflow sleeve assembly includes a heating pipe 53 and a cooling pipe 54, as well as an outer main pipe. The heating pipe 53 and the cooling pipe 54 are disposed in the outer main pipe, which improves the installation stability and neatness of the inflow sleeve assembly.

[0069] Optionally, the air conditioning indoor heat exchange assembly further includes a second heat exchange module, which includes a third heat exchange element 43, a fourth heat exchange element 44, and a third transfer valve 300. The third heat exchange element 43 is provided with a third heat exchange outlet 432, and the fourth heat exchange element 44 is provided with a fourth heat exchange outlet 442. The third transfer valve 300 includes a fifth transfer inlet 3001, a fifth transfer outlet 3003, a sixth transfer inlet 3002, and a sixth transfer outlet 3004. The fifth transfer outlet 3003 is connected to the third heat exchange outlet 432, and the sixth transfer outlet 3004 is connected to the fourth heat exchange outlet 442. Furthermore, the hot return water pipe 51 is connected to the fifth transfer inlet 3001, and the cold return water pipe 52 is connected to the sixth transfer inlet 3002. The third transfer valve 300 can selectively open the fifth transfer inlet 3001 and / or the sixth transfer inlet 3002. 2. When the fifth transfer inlet 3001 is open and the sixth transfer inlet 3002 is blocked, the third heat exchange outlet 432 and the fourth heat exchange outlet are both connected to the hot return water pipeline 51 via the fifth transfer inlet 3001. When both the fifth transfer inlet 3001 and the sixth transfer inlet 3002 are open, the third heat exchange outlet 432 is connected to the hot return water pipeline 51 via the fifth transfer inlet 3001, and the fourth heat exchange outlet 442 is connected to the cold return water pipeline 52 via the sixth transfer inlet 3002. When the fifth transfer inlet 3001 is blocked and the sixth transfer inlet 3002 is open, the third heat exchange outlet 432 and the fourth heat exchange outlet 442 are both connected to the cold return water pipeline 52 via the sixth transfer inlet 3002.

[0070] Similar to the first heat exchange module, the second heat exchange module has a third transfer valve 300 between its heat exchange outlet and the outflow sleeve assembly. This third transfer valve 300 allows for selective connection between the third heat exchange outlet 432 and the fourth heat exchange outlet 442 and the fifth transfer inlet 3001 and / or the sixth transfer inlet 3002. For example, when the air conditioning system is operating in cooling mode, the fifth transfer inlet 3001 of the third transfer valve 300 can be blocked while the sixth transfer inlet 3002 is open. In this case, the working fluid flowing out of both the third heat exchange outlet 432 and the fourth heat exchange outlet 442 can flow into the cold return water pipe 52 via the sixth transfer inlet 3002, enabling the air conditioning system to circulate cooling fluid. When the air conditioning system is in heating mode, the fifth inlet 3001 of the third transfer valve 300 can be opened while the sixth inlet 3002 is blocked. At this time, the working fluid flowing out of the third heat exchange outlet 432 and the fourth heat exchange outlet 442 can flow into the hot return water pipe 51 through the fifth inlet 3001, enabling the air conditioning system to perform a heating cycle. When the air conditioning system is in reheat dehumidification mode, both the fifth inlet 3001 and the sixth inlet 3002 of the third transfer valve 300 can be opened. At this time, the working fluid flowing out of the third heat exchange outlet 432 flows into the hot return water pipe 51 through the fifth inlet 3001, and the working fluid flowing out of the fourth heat exchange outlet 442 flows into the cold return water pipe 52 through the sixth inlet 3002, enabling the air conditioning system to perform a reheat dehumidification cycle.

[0071] Optionally, the third heat exchange element 43 is further provided with a third heat exchange inlet 431, and the fourth heat exchange element 44 is further provided with a fourth heat exchange inlet 441. The second heat exchange module also includes a fourth transfer valve 400, wherein the fourth transfer valve 400 includes a seventh transfer inlet 4001, a seventh transfer outlet 4003, an eighth transfer inlet 4002, and an eighth transfer outlet 4004. The seventh transfer outlet 4003 is connected to the third heat exchange inlet 431, and the eighth transfer outlet 4004 is connected to the fourth heat exchange inlet 441. In addition, the heating pipeline 53 is connected to the seventh transfer inlet 4001, and the cooling pipeline 54 is connected to the eighth transfer inlet 4002. Furthermore, the fourth transfer valve 400 can selectively open the seventh transfer inlet 4001 and / or the eighth transfer inlet 4002. In this case, the air conditioning system can operate in cooling mode. When the seventh transfer inlet 4001 is open and the eighth transfer inlet 4002 is blocked, the heating pipe 53 is connected to the third heat exchange inlet 431 and the fourth heat exchange inlet 441 via the seventh transfer inlet 4001. In this case, the air conditioning system can operate in heating mode. When both the seventh transfer inlet 4001 and the eighth transfer inlet 4002 are open, the heating pipe 53 is connected to the third heat exchange inlet 431 via the seventh transfer inlet 4001, and the cooling pipe 54 is connected to the fourth heat exchange inlet 441 via the eighth transfer inlet 4002.

[0084] The following example uses a hot-end heat exchanger and a cold-end heat exchanger as water-fluorine heat exchangers, with the first heat exchange module located in the first room and the second heat exchange module located in the second room, to illustrate different operating modes of the air conditioning system.

[0085] The outlet end of the second heat exchange pipe 812 of the hot end heat exchanger 81 is connected to the heating pipe 53 flowing into the casing assembly, and the inlet end of the second heat exchange pipe 812 is connected to the hot return water pipe 51 flowing out of the casing assembly.

[0086] The air conditioning system provided in this embodiment can simultaneously cool the first room and the second room.

[0087] On the outdoor unit side of the air conditioner, the low-temperature, low-pressure gaseous refrigerant is compressed into a high-temperature, high-pressure gas by the compressor 6. This high-temperature, high-pressure gaseous refrigerant directly enters the outdoor heat exchanger 7, where it acts as a condenser. The refrigerant at the outlet of the outdoor heat exchanger 7 becomes liquid, and then, through the throttling effect of the second throttling element 92, it becomes a low-temperature, low-pressure gaseous refrigerant. It then flows into the cold-end heat exchanger 82, completes heat exchange, and returns to the compressor 6, thus completing one refrigerant cycle. At this time, the three-way valve 95 controls the refrigeration bypass pipe 61 to close. On the indoor heat exchange component side, the first solenoid on / off valve controls the hot return water pipe to be blocked, the second solenoid on / off valve controls the cold return water pipe to be open, the third solenoid on / off valve controls the heating pipe to be blocked, and the fourth solenoid on / off valve controls the cooling pipe to be open. At this time, the fourth heat exchange pipe exchanges heat in the cold end heat exchanger to obtain cooling capacity, and flows into the first heat exchange element 41, the second heat exchange element 42, the third heat exchange element 43 and the fourth heat exchange element 44, which are evaporators, respectively, for cooling.

[0088] In this operating mode, the first transfer valve 100 blocks the first transfer inlet 11 and opens the second transfer inlet 13; the second transfer valve 200 blocks the third transfer inlet 2001 and opens the fourth transfer inlet 2002, connecting the cooling supply pipe 54 and the cold return water pipe 52 to the first heat exchange element 41 and the second heat exchange element 42, respectively. Furthermore, the third transfer valve 300 blocks the fifth transfer inlet 3001 and opens the sixth transfer inlet 3002; the fourth transfer valve 400 blocks the seventh transfer inlet 4001 and opens the eighth transfer inlet 4002, connecting the cooling supply pipe 54 and the cold return water pipe 52 to the third heat exchange element 43 and the fourth heat exchange element 44, respectively. Optionally, the opening states of the first transfer valve 100, the second transfer valve 200, the third transfer valve 300, and the fourth transfer valve 400 are as follows: Figure 14 As shown.

[0089] The air conditioning system provided in this embodiment can heat both the first room and the second room simultaneously.

[0090] On the outdoor unit side of the air conditioner, the low-temperature, low-pressure gaseous refrigerant is compressed into a high-temperature, high-pressure gas by the compressor 6. This high-temperature, high-pressure gaseous refrigerant directly enters the hot-end heat exchanger 81 for sufficient heat exchange. The refrigerant then flows into the outdoor heat exchanger 7 after being throttled by the first throttling element 91, becoming a low-temperature, low-pressure gas. At this time, the three-way valve 95 opens the refrigerant bypass pipe 61 and blocks the third heat exchange pipe 821 of the cold-end heat exchanger 82. The refrigerant flows back to the compressor 6 through the refrigerant bypass pipe 61, thus completing one refrigerant cycle. On the indoor heat exchange component side, the first and third solenoid on / off valves are open, while the second and fourth solenoid on / off valves are closed. At this time, the second heat exchange pipe gains heat in the hot-end heat exchanger and flows into the first heat exchange element 41, the second heat exchange element 42, the third heat exchange element 43, and the fourth heat exchange element 44, which serve as condensers, respectively, for heating.

[0091] In this operating mode, the first transfer valve 100 opens the first transfer inlet 11 and blocks the second transfer inlet 13; the second transfer valve 200 opens the third transfer inlet 2001 and blocks the fourth transfer inlet 2002, connecting the heating pipeline 53 and the hot return water pipeline 51 to the first heat exchange element 41 and the second heat exchange element 42, respectively. Furthermore, the third transfer valve 300 opens the fifth transfer inlet 3001 and blocks the sixth transfer inlet 3002; the fourth transfer valve 400 opens the seventh transfer inlet 4001 and blocks the eighth transfer inlet 4002, connecting the heating pipeline 53 and the hot return water pipeline 51 to the third heat exchange element 43 and the fourth heat exchange element 44, respectively. Optionally, the opening states of the first transfer valve 100, the second transfer valve 200, the third transfer valve 300, and the fourth transfer valve 400 are as follows: Figure 13 As shown.

[0092] The air conditioning system provided in this embodiment can cool the first room and heat the second room.

[0093] On the outdoor unit side of the air conditioner, the low-temperature, low-pressure gaseous refrigerant is compressed into a high-temperature, high-pressure gas by the compressor 6. The high-temperature, high-pressure gaseous refrigerant directly enters the hot-end heat exchanger 81 for full heat exchange. The refrigerant is then throttled by the first throttling element 91 and becomes a low-temperature, low-pressure gas that flows into the outdoor heat exchanger 7. At this time, the three-way valve 95 blocks the refrigerant bypass pipe 61 and opens the third heat exchange pipe 821 of the cold-end heat exchanger 82. The refrigerant flows back to the compressor 6 through the third heat exchange pipe 821, thus completing one refrigerant cycle. On the indoor heat exchange component side, the first electromagnetic on / off valve, the second electromagnetic on / off valve, the third electromagnetic on / off valve, and the fourth electromagnetic on / off valve are all turned on. At this time, the fourth heat exchange pipe 822 exchanges heat in the cold end heat exchanger 82 to obtain cooling capacity, and flows into the first heat exchange element 41 and the second heat exchange element 42, which serve as evaporators, to cool the first room. The second heat exchange pipe 812 exchanges heat in the hot end heat exchanger 81 to obtain heat capacity, and flows into the third heat exchange element 43 and the fourth heat exchange element 44, which serve as condensers, to heat the second room.

[0094] In this operating mode, the first transfer valve 100 blocks the first transfer inlet 11 and opens the second transfer inlet 13; the second transfer valve 200 blocks the third transfer inlet 2001 and opens the fourth transfer inlet 2002, connecting the cooling supply pipe 54 and the cold return water pipe 52 to the first heat exchange element 41 and the second heat exchange element 42, respectively. Furthermore, the third transfer valve 300 opens the fifth transfer inlet 3001 and blocks the sixth transfer inlet 3002; the fourth transfer valve 400 opens the seventh transfer inlet 4001 and blocks the eighth transfer inlet 4002, connecting the heating supply pipe 53 and the hot return water pipe 51 to the third heat exchange element 43 and the fourth heat exchange element 44, respectively. Optionally, the opening states of the first transfer valve 100 and the second transfer valve 200 are as follows: Figure 14 As shown, the conduction states of the third transfer valve 300 and the fourth transfer valve 400 are as follows: Figure 13 As shown.

[0095] The air conditioning system provided in this embodiment can provide reheat and dehumidification for both the first and second rooms. In this embodiment, the refrigerant circulation pattern on the outdoor unit side is the same as in the embodiment where the first room is cooled and the second room is heated.

[0096] On the indoor heat exchange component side, the first, second, third, and fourth electromagnetic on / off valves are all open. At this time, the fourth heat exchange pipe 822 exchanges heat in the cold end heat exchanger 82 to obtain cooling capacity, and flows into the second heat exchange element 42 and the fourth heat exchange element 44, which serve as evaporators, to dehumidify the first and second rooms. The second heat exchange pipe 812 exchanges heat in the hot end heat exchanger 81 to obtain heat, and flows into the first heat exchange element 41 and the third heat exchange element 43, which serve as condensers, to heat the air in the first and second rooms after dehumidification, thereby achieving reheat dehumidification in the first and second rooms respectively.

[0097] In this operating mode, the first transfer valve 100 connects the first transfer inlet 11 and the second transfer inlet 13, and the second transfer valve 200 connects the third transfer inlet 2001 and the fourth transfer inlet 2002, connecting the cooling supply pipeline 54 and the cold return water pipeline 52 to the second heat exchange element 42, and connecting the heating supply pipeline 53 and the hot return water pipeline 51 to the first heat exchange element 41. Optionally, the third transfer valve 300 connects the fifth transfer inlet 3001 and the sixth transfer inlet 3002, and the fourth transfer valve 400 connects the seventh transfer inlet 4001 and the eighth transfer inlet 4002, connecting the cooling supply pipeline 54 and the cold return water pipeline 52 to the fourth heat exchange element 44, and connecting the heating supply pipeline 53 and the hot return water pipeline 51 to the third heat exchange element 43. The conduction states of the first switching valve 100, the second switching valve 200, the third switching valve 300, and the fourth switching valve 400 are as follows: Figure 15 or Figure 16 As shown.

[0098] The air conditioning system provided in this embodiment can cool a first room and reheat and dehumidify a second room. In this embodiment, the refrigerant circulation pattern on the outdoor unit side is the same as in the embodiment where the first room is cooled and the second room is heated.

[0099] On the indoor heat exchange component side, the first, second, third, and fourth solenoid on / off valves are all open. At this time, the fourth heat exchange pipe 822 exchanges heat in the cold end heat exchanger 82 to obtain cooling capacity, and flows into the first heat exchange element 41, the second heat exchange element 42, and the fourth heat exchange element 44, which serve as evaporators, to cool the first room and dehumidify the second room. The second heat exchange pipe 812 exchanges heat in the hot end heat exchanger 82 to obtain heat capacity, and flows into the third heat exchange element 43, which serves as a condenser, to reheat the dehumidified air in the second room.

[0100] In this operating mode, the first transfer valve 100 blocks the first transfer inlet 11 and opens the second transfer inlet 13; the second transfer valve 200 blocks the third transfer inlet 2001 and opens the fourth transfer inlet 2002, thus connecting the cooling supply pipeline 54 and the cold return water pipeline 52 to the first heat exchange element 41 and the second heat exchange element 42, respectively. Optionally, the opening states of the first transfer valve 100 and the second transfer valve 200 are as follows: Figure 14 As shown. Optionally, the third transfer valve 300 connects the fifth transfer inlet 3001 and the sixth transfer inlet 3002, and the fourth transfer valve 400 connects the seventh transfer inlet 4001 and the eighth transfer inlet 4002, so that the cooling supply pipeline 54 and the cold return water pipeline 52 are respectively connected to the fourth heat exchange element 44, and the heating supply pipeline 53 and the hot return water pipeline 51 are respectively connected to the third heat exchange element 43. The conduction states of the third transfer valve 300 and the fourth transfer valve 400 are as follows. Figure 15 or Figure 16 As shown.

[0101] The air conditioning system provided in this embodiment can reheat and dehumidify a first room and heat a second room. In this embodiment, the refrigerant circulation pattern on the outdoor unit side of the air conditioner is the same as in the embodiment where the first room is cooled and the second room is heated.

[0102] On the indoor heat exchange component side, the first, second, third, and fourth solenoid on / off valves are all open. At this time, the fourth heat exchange pipe exchanges heat in the cold end heat exchanger to obtain cooling capacity, and flows into the second heat exchange element, which serves as an evaporator, to dehumidify the first room. The second heat exchange pipe exchanges heat in the hot end heat exchanger to obtain heat capacity, and flows into the first, third, and fourth heat exchange elements, which serve as condensers, to reheat the dehumidified air in the first room and heat the second room.

[0103] In this operating mode, the first transfer valve 100 connects the first transfer inlet 11 and the second transfer inlet 13, and the second transfer valve 200 connects the third transfer inlet 2001 and the fourth transfer inlet 2002, thereby connecting the cooling supply pipeline 54 and the cold return water pipeline 52 to the second heat exchange element 42, and connecting the heating supply pipeline 53 and the hot return water pipeline 51 to the first heat exchange element 41. The conduction states of the first transfer valve 100, the second transfer valve 200, the third transfer valve 300, and the fourth transfer valve 400 are as follows: Figure 15 or Figure 16 As shown. The third transfer valve 300 opens the fifth transfer inlet 3001 and blocks the sixth transfer inlet 3002, and the fourth transfer valve 400 opens the seventh transfer inlet 4001 and blocks the eighth transfer inlet 4002, so that the heating pipeline 53 and the hot return water pipeline 51 are connected to the third heat exchange element 43 and the fourth heat exchange element 44 respectively. The conduction states of the third transfer valve 300 and the fourth transfer valve 400 are as follows. Figure 13 As shown.

[0104] It is understood that when the indoor heat exchange components also include a third heat exchange module disposed in a third room, or other heat exchange modules disposed in other rooms, the air conditioning system provided in this disclosure embodiment can operate in different modes for multiple rooms respectively.

[0105] The air conditioning system provided in this embodiment can also perform defrosting without shutting down while heating the first and second rooms.

[0106] Optionally, when the air conditioning system is defrosting without stopping, the three-way valve 95 blocks the refrigeration bypass pipe 61 and opens the third heat exchange pipe 821 of the cold end heat exchanger 82. The conduction mode of the working fluid, solenoid on / off valve and transfer valve in the air conditioning system is the same as that in the heating mode.

[0107] This disclosure further provides the structures of a first switching valve 100, a second switching valve 200, a third switching valve 300, and a fourth switching valve 400. Optionally, the structures of the second switching valve 200, the third switching valve 300, and the fourth switching valve 400 are completely identical to the structure of the first switching valve 100, wherein... Figures 6 to 16 In the diagram, 11 represents the first transfer inlet 11, the third transfer inlet 2001, the fifth transfer inlet 3001, or the seventh transfer inlet 4001; 12 represents the first transfer outlet 12, the third transfer outlet 2003, the fifth transfer outlet 3003, or the seventh transfer outlet 4003; 13 represents the second transfer inlet 13, the fourth transfer inlet 2002, the sixth transfer inlet 3002, or the eighth transfer inlet 4002; and 14 represents the second transfer outlet 14, the fourth transfer outlet 2004, the sixth transfer outlet 3004, or the eighth transfer outlet 4004.

[0108] The structure of the first transfer valve is described below.

[0109] This disclosure provides a first adapter valve, such as... Figures 6 to 16As shown, the device includes a housing 1, a first slider 21, a second slider 22, and a drive assembly. The housing 1 has a valve chamber inside. The housing 1 includes a corresponding first transition inlet 11 and a first transition outlet 12, as well as corresponding second transition inlets 13 and second transition outlets 14. A first partition chamber 1011 is reserved between the first transition inlet 11 and the first sidewall 101 of the housing 1. The first slider 21 can slide within the valve chamber to block or avoid the first transition inlet 11. The second slider 22 can slide within the valve chamber to block or avoid the second transition inlet 13. The drive assembly drives the first slider 21 and the second slider 22 to slide synchronously within the valve chamber. Specifically, the drive assembly can drive the first slider 21 to slide between a first blocking position and a first avoiding position within the valve chamber, and the first avoiding position is located in the first partition chamber 1011.

[0110] The first transfer inlet 11, the second transfer inlet 13, the first transfer outlet 12, and the second transfer outlet 14 are all connected to the valve cavity. The first transfer inlet 11 corresponds to the first transfer outlet 12, meaning that, in the absence of other obstructions or flow guiding elements, fluid flowing into the first transfer inlet 11 can preferentially flow out through the first transfer outlet 12. Similarly, the second transfer inlet 13 corresponds to the second transfer outlet 14, meaning that, in the absence of other obstructions or flow guiding elements, fluid flowing into the second transfer inlet 13 can preferentially flow out through the second transfer outlet 14.

[0111] Optionally, the housing 1 of the first transfer valve includes a corresponding first bottom shell 102 and a second bottom shell 103, with multiple sidewalls provided between the first bottom shell 102 and the second bottom shell 103. A first transfer inlet 11 and a second transfer inlet 13 are located on the first bottom shell 102, and a first transfer outlet 12 and a second transfer outlet 14 are located on the second bottom shell 103. The centerline of the first transfer inlet 11 and the centerline of the first transfer outlet 12 are connected to form a first preset connection line, and the centerline of the second transfer inlet 13 and the centerline of the second transfer outlet 14 are connected to form a second preset connection line. The first preset connection line and the second preset connection line are parallel to form two corresponding sets of inlets and outlets on the housing 1.

[0112] The first sidewall 101 is disposed between the first bottom shell 102 and the second bottom shell 103, and the first transition inlet 11 is closer to the first sidewall 101 than the second transition inlet 13. Optionally, the distances from the first transition inlet 11 and the first transition outlet 12 to the first sidewall 101 are equal. Here, the direction from the first transition inlet 11 to the second transition inlet 13 is defined as the sliding out direction, and the direction from the second transition inlet 13 to the first transition inlet 11 is defined as the sliding in direction. A first slider 21 and a second slider 22 are disposed in the valve cavity. The first slider 21 can slide in the valve cavity along the sliding out direction or the sliding in direction to block or avoid the first transition inlet 11; similarly, the second slider 22 can also slide synchronously with the first slider 21 in the valve cavity along the sliding out direction or the sliding in direction to block or avoid the second transition inlet 13.

[0113] A first partition chamber 1011 is reserved between the first transfer inlet 11 and the first sidewall 101. When the first slider 21 is in the first clearance position, the first clearance position is the first partition chamber 1011. Optionally, when the first slider 21 is in the first clearance position, the first slider 21 abuts against the first sidewall 101, that is, the first slider 21 is located at the innermost end of the valve cavity, and the first slider 21 and the second slider 22 are in the initial position, such as... Figure 13 As shown. It can be understood that the first partition chamber 1011 is part of the valve chamber and is connected to other parts of the valve chamber.

[0114] The first transition valve provided in this embodiment has a driving assembly for driving a first slider 21 and a second slider 22 to slide synchronously within the valve cavity. During the synchronous sliding process, the first slider 21 and the second slider 22 can form different blocking or avoidance effects on the first transition inlet 11, the first transition outlet 12, the second transition inlet 13, and the second transition outlet 14, thereby creating different fluid flow paths for the first transition inlet 11, the first transition outlet 12, the second transition inlet 13, and the second transition outlet 14. For example, when the first slider 21 is in an avoidance position relative to the first transition inlet 11, and the second slider 22 is in an blocking position relative to the second transition inlet 13, the fluid flowing in through the first transition inlet 11 can flow out through the first transition outlet 12 and the second transition outlet 14. This flow path forms the first three-way valve, such as... Figure 13 As shown. When the first slider 21 is in the blocking position relative to the first transition inlet 11, and the second slider 22 is in the avoidance position relative to the second transition inlet 13, the fluid flowing into the second transition inlet 13 can flow out through the first transition outlet 12 and the second transition outlet 14. This flow path forms a second three-way valve, as shown. Figure 14As shown, the first transfer valve provided in this embodiment integrates at least two three-way valves. Optionally, this embodiment does not impose many restrictions on the type of fluid; for example, it can be refrigerant or water. Furthermore, the first transfer inlet 11 and the second transfer inlet 13 can respectively receive fluids of different temperatures or different types.

[0115] Optionally, the valve cavity inside the housing 1 is a regular cuboid shape, the first partition chamber 1011 is cuboid, the first slider 21 is cuboid or cube, and the second slider 22 is cuboid or cube.

[0116] Optionally, a second partition chamber 1012 is reserved between the first transfer port 11 and the second transfer port 13, such as... Figure 8 As shown. The driving component can drive the first slider 21 to slide between a first blocking position and a second avoidance position within the valve cavity, and the second avoidance position is located in the second partition chamber 1012. When the first slider 21 is in the second avoidance position, the second avoidance position is located in the second partition chamber 1012. That is, when the first slider 21 is in the second avoidance position, the first slider 21 is located between the first transition inlet 11 and the second transition inlet 13, as shown. Figure 16 As shown. It can be understood that the second partition chamber 1012 is part of the valve chamber and is connected to other parts of the valve chamber. Optionally, the second partition chamber 1012 is cuboid in shape.

[0117] The drive assembly drives the first slider 21 and the second slider 22 to slide synchronously within the valve cavity. When the drive assembly drives the first slider 21 and the second slider 22 to slide in the sliding direction, the first slider 21 is in the first avoidance position, the first blocking position, and the second avoidance position in sequence. When the first slider 21 is in the second avoidance position, the first slider 21 avoids the first transition inlet 11 without blocking the second transition inlet 13.

[0118] Optionally, the distance Y1 between the first transition inlet 11 and the first transition outlet 12 is equal to the length Y2 of the first slider 21. When the first slider 21 is in the first blocking position, one end of the first slider 21 abuts against the first transition inlet 11, and the other end abuts against the first transition outlet 12, as shown. Figure 10 As shown.

[0119] The distance between the first transition inlet 11 and the first transition outlet 12 can be understood as the vertical distance between the first transition inlet 11 and the first transition outlet 12 within the valve cavity. The length of the first slider 21 can be understood as the length of the first slider 21 along the direction from the first transition inlet 11 to the first transition outlet 12. In this embodiment, the distance between the first transition inlet 11 and the first transition outlet 12 is equal to the length of the first slider 21. Thus, when the first slider 21 is in the first blocking position, one end of the first slider 21 abuts against the first transition inlet 11, completely blocking the first transition inlet 11, while the other end of the first slider 21 abuts against the first transition outlet 12. At this time, the other end of the first slider 21 can at least partially block the first transition outlet 12.

[0120] Optionally, along the direction from the first transfer inlet 11 to the first transfer outlet 12, the first slider 21 includes an upper slider portion and a lower slider portion, wherein the lower slider portion is provided with a first conductive portion 211 connecting the valve chamber and the first transfer outlet 12. When the first slider 21 is in the first blocked position, the liquid in the valve chamber can flow out from the first transfer outlet 12 through the first conductive portion 211, such as... Figure 14 As shown.

[0121] Optionally, along the direction from the first transfer inlet 11 to the first transfer outlet 12, the first slider 21 is divided at 1 / 2 to obtain an upper slider portion and a lower slider portion. The lower slider portion of the first slider 21 is provided with a first conductive portion 211 connecting the valve chamber and the first transfer outlet 12. When the first slider 21 is in the first blocking position, the liquid in the valve chamber can flow out from the first transfer outlet 12 through the first conductive portion 211. In this way, while the first slider 21 completely blocks the first transfer inlet 11, the liquid in the valve chamber can flow out from the first transfer outlet 12 through the first conductive portion 211, that is, the first slider 21 does not completely block the first transfer outlet 12.

[0122] Optionally, the first conductive part 211 includes a first conductive end communicating with the valve cavity, wherein the first conductive end faces the second spacer chamber 1012.

[0123] The first conducting end of the first conducting section 211 faces the second spacer chamber 1012, so that fluid in the second spacer chamber 1012 within the valve chamber can flow out through the first conducting section 211 from the first transition outlet 12. That is, the aforementioned flow path of the second three-way valve, which flows in from the second transition inlet 13 and out through the first transition outlet 12 and the second transition outlet 14, is formed. Figure 14 As shown.

[0124] Optionally, the first conductive portion 211 is a notch formed on the lower slider portion, the notch facing the second spacer chamber 1012, and the notch only occupies the portion of the end of the first slider 21 that abuts against the first transfer outlet 12. That is, the end of the first slider 21 that abuts against the first transfer outlet 12 includes the notch and the abutting portion. In this way, when the first slider 21 is in the first blocking position, the fluid in the second spacer chamber 1012 can flow out from the first transfer outlet 12 through the notch, and the abutting portion partially blocks the first transfer outlet 12. Optionally, the abutting portion is located near the first spacer chamber 1011.

[0125] Optionally, the first conductive part 211 can also be a valve plate.

[0126] Optionally, a second conductive section 221 is provided between the second slider 22 and the second transition outlet 14, such as... Figure 13 and Figure 14 As shown, when the second slider 22 is in the second blocking position blocking the second transfer inlet 13, the liquid in the valve chamber can flow out from the second transfer outlet 14 through the second guide part 221.

[0127] When the second slider 22 is in the second blocking position, blocking the second transfer inlet 13, one end of the second slider 22 completely blocks the second transfer inlet 13. A second guide portion 221 is provided between the second slider 22 and the second transfer outlet 14, allowing liquid in the valve chamber to flow out through the second guide portion 221 from the second transfer outlet 14. Optionally, the second guide portion 221 is connected to the second partition chamber 1012 of the valve chamber, allowing fluid in the second partition chamber 1012 to flow out through the second transfer outlet 14. This forms the flow path of the first three-way valve, where fluid flows in through the first transfer inlet 11 and out through the first transfer outlet 12 and the second transfer outlet 14. Figure 13 As shown.

[0128] Optionally, the distance Y3 between the second transfer inlet 13 and the second transfer outlet 14 is greater than the length Y4 of the second slider 22.

[0129] The distance Y3 between the second transition inlet 13 and the second transition outlet 14 can be understood as the vertical distance from the second transition inlet 13 to the second transition outlet 14 within the valve cavity, and the length Y4 of the second slider 22 can be understood as the length of the second slider 22 in the direction from the second transition inlet 13 to the second transition outlet 14. In this embodiment, the distance Y3 between the second transition inlet 13 and the second transition outlet 14 is greater than the length Y4 of the second slider 22. This ensures that when the second slider 22 is in the second blocking position, one end of the second slider 22 can block the second transition inlet 13, while the other end of the second slider 22 has a gap with the second transition outlet 14, forming the aforementioned second conductive part 221.

[0130] Optionally, the distance between the first transition inlet 11 and the second transition inlet 13 is a first distance x4, the distance between the first slider 21 and the second slider 22 is a second distance, and the sum of the width x1 of the first transition inlet 11 and the first distance x4 is equal to the second distance, so that the first slider 21 and the second slider 22 can slide to the initial position under the drive of the drive component. When the first slider 21 and the second slider 22 are in the initial position, the first slider 21 is in the first clearance position and the second slider 22 is in the second blocking position, so that the fluid flowing in through the first transition inlet 11 can flow out through the first transition outlet 12 and the second transition outlet 14.

[0131] In this embodiment, the distance between the first transition inlet 11 and the second transition inlet 13 forms a first distance X4, and the positions of the first transition inlet 11 and the first distance X4 are close to each other. The distance between the first slider 21 and the second slider 22 is a second distance, and the sum of the width X1 of the first transition inlet 11 and the first distance X4 is equal to the second distance. This ensures that when the first slider 21 and the second slider 22 are in their initial positions, the first slider 21 is in a first clearance position that avoids the first transition inlet 11, and the second slider 22 is in a second blocking position that blocks the second transition inlet 13, allowing the fluid flowing in through the first transition inlet 11 to flow out through the first transition outlet 12 and the second transition outlet 14. It is understood that in this flow state, fluid flows in through the first transition inlet 11, a portion flows out through the first transition outlet 12, and the other portion flows into the second partition chamber 1012 and then flows out through the second guide portion 221 from the second transition outlet 14.

[0132] Optionally, the width x2 of the second slider 22 is smaller than the second spacing, so that the first slider 21 and the second slider 22 can slide to the middle position under the drive of the drive assembly. When the first slider 21 and the second slider 22 are in the middle position, the first slider 21 is in a first blocking position, and the second slider 22 is in a third clearance position that avoids the second transfer inlet 13, allowing fluid flowing in through the second transfer inlet 13 to flow out through the first transfer outlet 12 and the second transfer outlet 14. Figure 14 As shown.

[0133] In this embodiment, the width x2 of the second slider 22 is less than the second spacing. Thus, when the first slider 21 slides to the first blocking position, the sliding distance formed by the second slider 22 can completely avoid the second transfer inlet 13, allowing the fluid flowing in through the second transfer inlet 13 to flow out through the first transfer outlet 12 and the second transfer outlet 14. It is understood that in this flow state, fluid flows in through the second transfer inlet 13, a portion flows out through the second transfer outlet 14, and the other portion flows into the second spacer chamber 1012 and then flows out through the first conductive part 211 from the first transfer outlet 12.

[0134] Optionally, the width X3 of the first slider 21 is greater than or equal to the width X1 of the first transition inlet 11, so that the first slider 21 can slide to the flow adjustment position under the drive of the drive assembly. When the first slider 21 is in the flow adjustment position, a portion of the first slider 21 blocks the first transition inlet 11, and the other portion of the first slider 21 is in a second clearance position to adjust the amount of fluid flowing in through the first transition inlet 11 and out through the first transition outlet 12. Figure 15 As shown.

[0135] In this embodiment, the width X3 of the first slider 21 is greater than or equal to the width X1 of the first transition inlet 11. This ensures that during the sliding process from the first blocking position to the second avoidance position, the first slider 21 partially blocks the first transition inlet 11, i.e., the flow rate adjustment position. Thus, by adjusting the travel distance of the first slider 21 in the sliding direction using the driving component, the avoidance area formed by the first slider 21 relative to the first transition inlet 11 can be adjusted, thereby regulating the amount of fluid flowing into the first transition inlet 11 and out of the first transition outlet 12.

[0136] Optionally, the end of the first slider 21 that abuts against the first transfer outlet 12 includes a notch and an abutment portion. It is understood that when the first slider 21 is in the flow regulation position, the notch of the first slider 21 slides completely into the second spacer chamber 1012, and the abutment portion of the first slider 21 abuts against the first transfer outlet 12. This allows the fluid flowing in through the second transfer inlet 13 to completely flow out through the second transfer outlet 14 when the first slider 21 is in the flow regulation position. Figure 15 As shown.

[0137] Optionally, the width X1 of the first slider 21 is equal to the first spacing, so that the first slider 21 and the second slider 22 can slide to the termination position under the drive of the drive assembly. When the first slider 21 and the second slider 22 are in the termination position, the first slider 21 is in the second clearance position, and the second slider 22 is in the fourth clearance position, clearing the second transfer inlet 13. This allows fluid flowing in through the first transfer inlet 11 to flow out through the first transfer outlet 12, and fluid flowing in through the second transfer inlet 13 to flow out through the second transfer outlet 14. Figure 16 As shown.

[0138] As mentioned above, the first spacing is the distance formed between the first transfer inlet 11 and the second transfer inlet 13. In the first transfer valve provided in this embodiment, the width X1 of the first slider 21 is equal to the first spacing X4, so that when the first slider 21 is in the second clearance position, the first slider 21 can clear both the first transfer inlet 11 and the second transfer inlet 13 without obstructing the second transfer inlet 13. This allows fluid flowing in through the first transfer inlet 11 to flow out through the first transfer outlet 12, and fluid flowing in through the second transfer inlet 13 to flow out through the second transfer outlet 14.

[0139] Optionally, the width of the second slider 22 is greater than or equal to the width x2 of the second transition inlet 13.

[0140] The width of the second slider 22 is at least equal to the width of the second transition entrance 13 x 2, so that the second slider 22 can completely block the second transition entrance 13 when in the second blocking position.

[0141] Optionally, the housing 1 includes a liquid flow housing and a slide housing. The liquid flow housing has a liquid flow cavity 110 inside, and is provided with a first transfer inlet 11, a first transfer outlet 12, a second transfer inlet 13, and a second transfer outlet 14. The slide housing has a slide cavity 120 inside, used to provide a third clearance position and a fourth clearance position for the second slider 22, such as... Figure 12 As shown.

[0142] The housing 1 includes a liquid flow housing and a slide housing. The liquid flow housing has the aforementioned first transfer inlet 11, first transfer outlet 12, second transfer inlet 13, and second transfer outlet 14, and internally forms a liquid flow cavity 110 for fluid flow. The slide housing has an internal slide cavity 120 for providing a third and fourth clearance position for the second slider 22. Optionally, the cross-sectional area of ​​the second slider 22 is less than or equal to the cross-sectional area of ​​the slide cavity 120, allowing the second slider 22 to slide smoothly within the slide cavity 120. The cross-sectional area of ​​the liquid flow cavity 110 is greater than the cross-sectional area of ​​the slide cavity 120.

[0143] Optionally, in this embodiment, the width relationship of each part in the first transfer valve will be described in detail so that the first slider 21 and the second slider 22 can be in the initial position, the flow adjustment position, and the termination position sequentially when sliding in the sliding direction. For example Figure 9 As shown, the width X1 of the first transition inlet 11 is 1 / 2δ, the width X2 of the second transition inlet 13 is 1 / 2δ, the width X3 of the first partition chamber 1011 is δ, the width X4 of the second partition chamber 1012 is δ, and the width X5 of the slide cavity 120 is 3 / 2δ. Optionally, δ is 50mm.

[0144] When the first slider 21 and the second slider 22 are in their initial positions, as follows: Figure 13 As shown, the first slider 21 is located in the first clearance position, which avoids the first transfer inlet 11. The second slider 22 is located in the second blocking position, which blocks the second transfer inlet 13. At this time, the fluid flows in through the first transfer inlet 11 and flows out through the first transfer outlet 12 and the second transfer outlet 14, forming the flow path of the first three-way valve.

[0145] The driving component drives the first slider 21 and the second slider 22 to travel 1 / 2δ along the sliding direction, and the first slider 21 and the second slider 22 slide to the middle position, as shown. Figure 14 As shown, at this time, the first slider 21 is in the first blocking position, the second slider 22 is in the third clearance position, the fluid flows in through the second transfer inlet 13, and flows out through the first transfer outlet 12 and the second transfer outlet 14, forming the flow path of the second three-way valve.

[0146] The drive assembly continues to drive the first slider 21 and the second slider 22 to continue moving 1 / 2δ~δ along the sliding direction from the middle position, and the first slider 21 and the second slider 22 slide to the flow adjustment position, such as Figure 15As shown. At this time, fluid flows in through the first transfer inlet 11 and out through the first transfer outlet 12, and fluid flows in through the second transfer inlet 13 and out through the second transfer outlet 14. Simultaneously, the first slider 21 partially blocks the first transfer inlet 11, and the amount of fluid flowing in through the first transfer inlet 11 and out through the first transfer outlet 12 can be adjusted by controlling the sliding distance of the control valve stem 31.

[0147] The drive assembly continues to drive the first slider 21 and the second slider 22 to continue moving δ along the sliding direction from the middle position. The first slider 21 and the second slider 22 slide to the end position, as shown. Figure 16 As shown. The first slider 21 is located in the second clearance position, and the second slider 22 is located in the fourth clearance position, which avoids the second transfer inlet 13. At this time, the fluid can flow in through the first transfer inlet 11 at maximum flow rate and flow out from the first transfer outlet 12, and the fluid can flow in through the second transfer inlet 13 at maximum flow rate and flow out from the second transfer outlet 14.

[0148] Optionally, the drive assembly includes a drive element and a valve stem 31 that moves within the valve cavity under the drive of the drive element, wherein the first slider 21 and the second slider 22 are connected to the valve stem 31.

[0149] In this embodiment, the valve stem 31 can move along the aforementioned sliding out and sliding in directions under the drive of the driving element, thereby causing the first slider 21 and the second slider 22 to slide along the sliding out and sliding in directions. Optionally, the first slider 21 and the second slider 22 are fixedly disposed on the valve stem 31 in a through-type manner.
