The compressor 10, the outdoor heat exchanger 20, the indoor heat exchanger 30, the hot water heat exchanger 42 and the control valve set 50 are all arranged on the circulation pipeline 60, the circulation pipeline 60 is provided with a first refrigerant flow path which is conducted through the control valve set 50, and when the control valve set 50 conducts the first refrigerant flow path, the hot water heat exchanger 42 and the outdoor heat exchanger 20 jointly form a first heat exchanger set which exchanges heat with the indoor heat exchanger 30.
Specifically, the control valve set 50 can adjust the flow direction of the refrigerant in the circulation pipeline 60, so that the refrigerant in the circulation pipeline 60 can flow along the first refrigerant flow path, and thus, both the hot water heat exchanger 42 and the outdoor heat exchanger 20 can exchange heat with the indoor heat exchanger 30 through the refrigerant flowing in the circulation pipeline 60.
The hot water heat exchanger 42 is to exchange heat with water in the water tank 41 to heat the water in the water tank 41 into hot water. The hot water in the water tank 41 can be used for providing domestic water for washing, bathing and the like for a user, and can also be introduced into an indoor heating pipeline to meet the heating requirement of the user in cold seasons.
Referring to fig. 1, the water heating apparatus 40 may further be provided with an electric auxiliary heating structure for auxiliary heating of water in the water tank 41, as required.
The embodiment of the application provides a circulation pipeline 60 of air conditioner hot water machine has the first refrigerant flow path that switches on through valve unit 50, switch on first refrigerant flow path when valve unit 50, hot water heat exchanger 42 and outdoor heat exchanger 20 constitute the first heat exchanger group with the heat transfer of indoor heat exchanger 30 jointly, therefore, when utilizing the air conditioner hot water machine to refrigerate indoor, also can heat the water in the water tank 41, thereby can reduce the energy waste effectively, improve the system energy efficiency of air conditioner hot water machine.
In one embodiment, the circulation pipeline 60 has a second refrigerant flow path conducted through the control valve set 50, and when the control valve set 50 conducts the second refrigerant flow path, the hot water heat exchanger 42 and the indoor heat exchanger 30 together form a second heat exchanger set for exchanging heat with the outdoor heat exchanger 20.
Specifically, the control valve group 50 can adjust a flow path of the refrigerant in the circulation line 60. When the refrigerant in the circulation line 60 flows along the second refrigerant flow path, both the hot water heat exchanger 42 and the indoor heat exchanger 30 can exchange heat with the outdoor heat exchanger 20 through the refrigerant flowing in the circulation line 60.
The specific connection form between the hot water heat exchanger 42, the outdoor heat exchanger 20, and the indoor heat exchanger 30 may be determined according to actual circumstances.
For example, referring to fig. 1, when the control valve set 50 connects the first refrigerant flow path, the hot water heat exchanger 42 is connected in parallel with the outdoor heat exchanger 20. That is, a part of the refrigerant flowing out of the compressor 10 flows into the hot water heat exchanger 42 to exchange heat with water in the water tank 41, another part of the refrigerant flows into the outdoor heat exchanger 20 to exchange heat, and the refrigerant flowing out of the hot water heat exchanger 42 and the refrigerant flowing out of the outdoor heat exchanger 20 flow into the indoor heat exchanger 30 together to exchange heat, so that the water in the water tank 41 can be heated into hot water by the hot water heat exchanger 42, and the interior of the room can be cooled by the indoor heat exchanger 30.
For another example, referring to fig. 2, when the control valve set 50 connects the second refrigerant flow path, the hot water heat exchanger 42 is connected in parallel with the indoor heat exchanger 30. That is, a part of the refrigerant flowing out of the compressor 10 flows into the hot water heat exchanger 42 to exchange heat with water in the tank 41, another part of the refrigerant flows into the indoor heat exchanger 30 to exchange heat, and the refrigerant flowing out of the hot water heat exchanger 42 and the refrigerant flowing out of the indoor heat exchanger 30 flow into the outdoor heat exchanger 20 together to exchange heat, whereby the water in the tank 41 can be heated by the hot water heat exchanger 42 to be hot water, and the indoor heat exchanger 30 can also heat the indoor space.
In one embodiment, referring to fig. 1, the circulation pipeline 60 includes an air-conditioning circulation main path 61 and a hot water heat exchange branch path 62 communicated with the air-conditioning circulation main path 61, the control valve set 50 includes an expansion valve 51 and a four-way valve 52, the compressor 10, the outdoor heat exchanger 20, the indoor heat exchanger 30, the expansion valve 51 and the four-way valve 52 are all disposed on the air-conditioning circulation main path 61, and the hot water heat exchanger 42 is disposed on the hot water heat exchange branch path 62.
Specifically, the main air-conditioning cycle path 61 is a pipe line through which the refrigerant circulates between the outdoor heat exchanger 20 and the indoor heat exchanger 30.
For example, the compressor 10, the outdoor heat exchanger 20, the indoor heat exchanger 30, the expansion valve 51, and the four-way valve 52 may be disposed on the air-conditioning cycle main path 61 in the same manner as the related art air-conditioning system.
The hot water heat exchange branch 62 is a pipeline externally connected to the main air-conditioning circulation path 61 and is used for being matched with the main air-conditioning circulation path 61 to realize the hot water making function of the air-conditioning water heater.
In one embodiment, referring to fig. 1, an inlet and an outlet of the compressor 10 are respectively and correspondingly communicated with a first connection port 52a and a second connection port 52b of the four-way valve 52, two ports of the indoor heat exchanger 30 are respectively and correspondingly communicated with the expansion valve 51 and a third connection port 52c of the four-way valve 52, and two ports of the outdoor heat exchanger 20 are respectively and correspondingly communicated with the expansion valve 51 and a fourth connection port 52d of the four-way valve 52.
Referring to fig. 1, when the valve block 50 is turned on to connect the first refrigerant flow path, the second connection port 52b of the four-way valve 52 is communicated with the fourth connection port 52d, and the first connection port 52a of the four-way valve 52 is communicated with the third connection port 52 c. Thus, the refrigerant flowing out of the compressor 10 flows through the four-way valve 52, the outdoor heat exchanger 20, the expansion valve 51, and the indoor heat exchanger 30 in sequence along the air-conditioning cycle main path 61, passes through the four-way valve 52, and flows back to the compressor 10, thereby implementing a function of cooling the indoor space by the air-conditioning water heater.
Referring to fig. 2, when the valve set 50 is turned on to control the second refrigerant flow path, the second connection port 52b and the third connection port 52c of the four-way valve 52 are communicated, and the first connection port 52a and the fourth connection port 52d of the four-way valve 52 are communicated. Thus, the refrigerant flowing out of the compressor 10 flows through the four-way valve 52, the indoor heat exchanger 30, the expansion valve 51, and the outdoor heat exchanger 20 in sequence along the air-conditioning circulation main path 61, passes through the four-way valve 52, and flows back to the compressor 10, thereby implementing a function of heating the indoor space by the air-conditioning water heater.
In one embodiment, the hot water heat exchange branch line 62 has a first sub-path through which the outlet 42a of the hot water heat exchanger communicates with the main air conditioning cycle path 61 between the expansion valve 51 and the outdoor heat exchanger 20, and a second sub-path through which the outlet 42a of the hot water heat exchanger communicates with the main air conditioning cycle path 61 between the expansion valve 51 and the indoor heat exchanger 30, and the control valve block 50 includes a hot water control valve 53 provided on the hot water heat exchange branch line 62.
Specifically, the refrigerant flowing out of the outlet of the hot water heat exchanger 42 can be switched between flowing along the first sub-path and flowing along the second sub-path by the hot water control valve 53. Thereby, the hot water heat exchanger 42 is enabled to switch between heat exchange with the indoor heat exchanger 30 and heat exchange with the outdoor heat exchanger 20.
It is understood that the hot water control valve 53 needs to be engaged with the four-way valve 52 such that the refrigerant in the circulation line 60 flows along the first refrigerant flow path or along the second refrigerant flow path.
When the control valve group 50 turns on the first refrigerant flow path, the four-way valve 52 turns on a refrigerant path on the main air-conditioning cycle path 61 that flows from the outlet of the compressor 10 to the outdoor heat exchanger 20, and the hot water control valve 53 turns on the first sub-path and turns off the second sub-path. Thus, the air-conditioning water heater can produce hot water through the hot water heat exchanger 42 while cooling through the indoor heat exchanger 30.
When the control valve group 50 turns on the second refrigerant flow path, the four-way valve 52 turns on the refrigerant path flowing from the outlet of the compressor 10 to the indoor heat exchanger 30 in the main air-conditioning cycle path 61, and the hot water control valve 53 turns on the second sub-path, and turns off the first sub-path. Thus, the air-conditioning water heater can be made to heat water by the hot water heat exchanger 42 while heating by the indoor heat exchanger 30.
It should be noted that the type and the arrangement of the hot water control valve 53 may be determined according to actual conditions.
For example, referring to fig. 1, the hot water control valve 53 includes a first control valve 531 having a first working port 531a, a second working port 531b and a third working port 531c, the hot water heat exchange branch line 62 includes a first pipe 621, a second pipe 622 and a third pipe 623, the first pipe 621 communicates the outlet 42a of the hot water heat exchanger with the first working port 531a, one end of the second pipe 622 with the second working port 531b, the other end of the second pipe 622 with the main air conditioning cycle path 61 between the expansion valve 51 and the outdoor heat exchanger 20, one end of the third pipe 623 with the third working port 531c, and the other end of the third pipe 623 with the main air conditioning cycle path 61 between the expansion valve 51 and the indoor heat exchanger 30.
Specifically, referring to fig. 1, when the first control valve 531 communicates the first working port 531a with the second working port 531b, the refrigerant flowing out of the outlet of the hot water heat exchanger 42 flows along the first pipeline 621 and the second pipeline 622, and then flows into the indoor heat exchanger 30 through the expansion valve 51 to exchange heat, so that the water in the water tank 41 can be heated while cooling the indoor space.
Referring to fig. 2, when the first control valve 531 communicates the first working port 531a with the third working port 531c, the refrigerant flowing out of the outlet of the hot water heat exchanger 42 flows along the first pipeline 621 and the third pipeline 623, and then flows into the outdoor heat exchanger 20 through the expansion valve 51 to exchange heat, so that the water in the water tank 41 can be heated while heating the indoor space.
It is understood that the first control valve 531 needs to cooperate with the four-way valve 52 to conduct the first refrigerant flow path or the second refrigerant flow path in the circulation line 60.
The first control valve 531 may be a two-position three-way valve or another control valve that can realize the switching function.
In another embodiment, referring to fig. 3, the hot water heat exchange branch line 62 includes a fourth line 624 and a fifth line 625, the hot water control valve 53 includes a first on-off valve 532 disposed on the fourth line 624 and a second on-off valve 533 disposed on the fifth line 625, one end of the fourth line 624 is communicated with the outlet 42a of the hot water heat exchanger, the other end of the fourth line 624 is communicated with the main air conditioning cycle path 61 between the expansion valve 51 and the outdoor heat exchanger 20, one end of the fifth line 625 is communicated with the fourth line 624 between the outlet 42a of the hot water heat exchanger and the first on-off valve 532, and the other end of the fifth line 625 is communicated with the main air conditioning cycle path 61 between the expansion valve 51 and the indoor heat exchanger 30.
That is, the first and second switching valves 532 and 533 may be engaged with each other to switch the first and second refrigerant flow paths.
Specifically, when the valve of the first on-off valve 532 is opened, the valve of the second on-off valve 533 is closed, and the refrigerant flowing out of the outlet of the hot water heat exchanger 42 flows along the fourth line 624. When the valve of the first on-off valve 532 is closed, the valve of the second on-off valve 533 is opened, and the refrigerant flowing out of the outlet of the hot water heat exchanger 42 flows through a portion of the fourth pipeline 624 and then flows along the fifth pipeline 625. That is, the first control valve 531 may be replaced with the first and second switching valves 532 and 533 to switch the first refrigerant flow path and the second refrigerant flow path.
In an embodiment, referring to fig. 1, the control valve set 50 further includes a second control valve 54, the second control valve 54 is disposed on the hot water heat exchanging branch 62 and located upstream of the hot water heat exchanger 42 along the refrigerant flowing direction, and when the second control valve 54 is in a closed state, the circulation pipeline 60 forms an independent cooling refrigerant path or an independent heating refrigerant path flowing along the air-conditioning circulation main path 61 and avoiding the hot water heat exchanging branch 62.
The independent refrigeration refrigerant path means a path in which the refrigerant flows only along the air conditioner circulation main path 61 and does not flow through the hot water heat exchange branch 62, and the refrigerant can realize independent refrigeration to the indoor space by flowing along the independent refrigeration refrigerant path.
The independent heating refrigerant path means a path in which the refrigerant flows only along the air-conditioning cycle main path 61, but not through the hot water heat exchange branch path 62, and the refrigerant can be heated alone by flowing along the independent heating refrigerant path.
That is, after the second control valve 54 is closed, the refrigerant can only flow along the main path 61 of the air conditioning cycle, but not through the hot water heat exchanging branch 62. Thus, the heating of the water in the tank 41 can be stopped as necessary, and only the indoor space can be independently cooled or heated.
The type of the second control valve 54 may be determined according to actual needs, and for example, the second control valve 54 may be a first flow control valve, which is closed to prevent the refrigerant from flowing into the hot water heat exchanger 42, and also controls the opening degree of the valve to adjust the flow rate of the refrigerant flowing through the hot water heat exchange branch 62.
In one embodiment, referring to fig. 2, the hot water heat exchange branch 62 includes a sixth pipe 626 having a first port end 626a and a second port end 626b, the first port end 626a is communicated with the main air conditioning cycle path 61 between the compressor 10 and the four-way valve 52, and the second port end 626b is communicated with the inlet 42b of the hot water heat exchanger 42.
That is, a portion of the refrigerant flowing out of the compressor 10 flows along the main air conditioning cycle path 61 and flows into the four-way valve 52, and another portion of the refrigerant flows along the hot water heat exchanging branch 62 and flows into the hot water heat exchanger 42.
Referring to fig. 2, a second control valve 54 may be disposed on the sixth pipeline 626, so as to control the flow rate of the refrigerant flowing into the hot water heat exchanger 42.
In one embodiment, referring to fig. 2, the control valve set 50 further includes a second flow control valve 55, and the second flow control valve 55 is disposed on the main air conditioning cycle path 61 between the first interface end 626a and the four-way valve 52.
Specifically, the second flow rate control valve 55 can adjust the flow rate of the refrigerant flowing into the four-way valve 52 by controlling the valve opening degree.
Further, the refrigerant flowing from the compressor 10 into the four-way valve 52 may be blocked by closing the second flow rate control valve 55.
For example, when the valve of the second flow control valve 55 is closed, all of the refrigerant flowing out of the compressor 10 flows into the hot water heat exchanger 42, and the refrigerant flowing out of the outlet of the hot water heat exchanger 42 may exchange heat only with the indoor heat exchanger 30 under the control of the control valve group 50, thereby achieving cooling while heating water. The refrigerant flowing out of the outlet of the hot water heat exchanger 42 may exchange heat only with the outdoor heat exchanger 20, so that the air-conditioning water heater can only provide hot water.
In some embodiments, the first flow control valve and the second flow control valve 55 are disposed in the circulation line 60, and cooperate to regulate the flow of the refrigerant in the circulation line 60.
In one embodiment, the control flow of the air-conditioning water heater under the refrigeration condition may be: when the air-conditioning water heater enters the cooling mode, the second connection port 52b and the fourth connection port 52d of the four-way valve 52 are communicated, the first connection port 52a and the third connection port 52c are communicated, the first working port 531a and the second working port 531b of the first control valve 531 are communicated, the valve opening degree of the second flow valve 55 and the first flow control valve is adjusted, a small amount of refrigerant flowing out of the compressor 10 flows into the outdoor heat exchanger 20 through the second flow valve 55 and the four-way valve 52, and a large amount of refrigerant flows into the hot water heat exchanger 42 through the first flow control valve. When the temperature of the water tank 41 reaches the set temperature, the first flow control valve is closed, and the valve opening of the second flow valve 55 is increased, so that the air-conditioning water heater is switched to the independent cooling mode in which heat exchange is performed only by the outdoor heat exchanger 20 and the indoor heat exchanger 30.
In one embodiment, the control flow of the air-conditioning water heater in the heating condition may be: when the air-conditioning water heater enters a heating mode, the second connection port 52b of the four-way valve 52 is communicated with the third connection port 52c, the first connection port 52a is communicated with the fourth connection port 52d, the first working port 531a and the third working port 531c of the first control valve 531 are communicated, the valve opening degree of the second flow valve 55 and the first flow control valve is adjusted, a small amount of refrigerant flowing out of the compressor 10 flows into the indoor heat exchanger 30 through the second flow valve 55 and the four-way valve 52, and a large amount of refrigerant flows into the hot water heat exchanger 42 through the first flow control valve. When the temperature of the water tank 41 reaches the set temperature, the first flow control valve is closed, and the valve opening degree of the second flow valve 55 is increased, so that the air-conditioning water heater is switched to the independent heating mode in which heat exchange is performed only by the outdoor heat exchanger 20 and the indoor heat exchanger 30.
In some embodiments, when the temperature of the water tank 41 reaches the set temperature, the valve of the second control valve 54 may be adjusted to be smaller to limit the flow of the refrigerant flowing into the hot water heat exchanger 42, and the valve opening of the second flow valve 55 may be increased.
