[0033] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0034] In order to solve the above problems, a first embodiment of the present invention provides an air conditioner, which can simultaneously operate the cooling mode and the heating mode by adopting the method, thereby meeting the needs of the air conditioner user for both cooling and heating.

[0035] Reference below Figure 1 An air conditioner according to an embodiment of the present invention is described. Figure 1As shown, the air conditioner 1000 includes a refrigerant circulation circuit, a control valve group 9 and a controller.

[0036] Among them, the refrigerant circulation flow path allows the refrigerant to circulate in the flow path composed of the vapor-liquid separator 1, the compressor 2, the fin heat exchanger 3, the throttling device 4, the liquid storage device 5, the heat exchanger group 6 and the four-way valve 7; the heat exchanger group 6 includes a plurality of refrigerant branches arranged in parallel, and each refrigerant branch is provided with a heat exchanger; the four-way valve 7 includes a first port, a second port, a third port and a fourth port, the first port is connected to the heat exchanger group 6, the second port is connected to the vapor-liquid separator 1, the third port is connected to the fin heat exchanger 3, and the fourth port is connected to the outlet of the compressor 2; the control valve group 9 is arranged on the refrigerant circulation flow path, and is used to conduct or cut off the refrigerant circulation flow path; the controller is connected to the control valve group 9 and the four-way valve 7.

[0037] The controller is configured to perform the following steps.

[0038] First, a target operation mode of the air conditioner is obtained, wherein the target operation mode at least includes a coordinated mode combining a heating mode and a cooling mode.

[0039] Specifically, the user can send control instructions about the operating mode to the air conditioner through the remote control, the air conditioning application in the mobile terminal or the control panel on the air conditioner body by language, gestures and other operating methods. The air conditioner receives the control instructions about the operating mode, and the controller obtains the target operating mode of the air conditioner. For example, the target operating mode of the air conditioner is a collaborative mode combining the heating mode and the cooling mode, or a heating mode or a cooling mode, and there is no restriction on this.

[0040] Then, the target operation mode of the air conditioner is determined to be the cooperative mode.

[0041] Exemplarily, if the air conditioner receives a control instruction of the cooperative mode, the controller acquires that the target operation mode of the air conditioner is the cooperative mode.

[0042] Finally, the switching states of the control valve group 9 and the four-way valve 7 are controlled according to the target operating mode to control a part of the heat exchangers in the heat exchanger group 6 to operate in the cooling mode and another part of the heat exchangers in the heat exchanger group 6 to operate in the heating mode.

[0043] Specifically, the existing air conditioner cannot run the cooling mode and the heating mode at the same time to meet the needs of the air conditioner users for cooling and heating at the same time. In order to solve this problem, in the present application, the switching state of the control valve group 9 and the switching state of the four-way valve 7 are controlled according to the target operation mode, so that the air conditioner can run the cooling mode and the heating mode at the same time, thereby meeting the needs of the air conditioner users for cooling and heating at the same time. That is to say, the heat exchanger group 6 is arranged in different spaces. When some users need to turn on the heating mode in a certain space, and other users need to turn on the cooling mode in another space, the target operation mode of the air conditioner is a collaborative mode combining the heating mode and the cooling mode. Then, according to the target operation mode, the switching state of the control valve group 9 and the switching state of the four-way valve 7 are controlled to control a part of the heat exchangers in the heat exchanger group 6 to run the cooling mode and control another part of the heat exchangers in the heat exchanger group 6 to run the heating mode, so that the air conditioner can run the cooling mode and the heating mode at the same time, thereby meeting the needs of the air conditioner users for cooling and heating at the same time.

[0044] In addition, when the target operating mode of the air conditioner is heating mode or cooling mode, the present application controls the switching state of the control valve group 9 and the switching state of the four-way valve 7 according to the target operating mode, thereby realizing the cooling or heating function.

[0045] According to the air conditioner of the embodiment of the present invention, when the target operating mode is a collaborative mode combining the heating mode and the cooling mode, by controlling the switching state of the control valve group 9 and the switching state of the four-way valve 7, different heat exchangers in the heat exchanger group 6 can operate in the cooling mode and the heating mode at the same time, thereby meeting the needs of the user of the air conditioner for both cooling and heating.

[0046] In some embodiments, Figure 1 As shown, the control valve group 9 includes: a first multi-way valve 901 , a second multi-way valve 902 , a third multi-way valve 903 , a fourth multi-way valve 904 , a fifth multi-way valve 905 , a sixth multi-way valve 906 , a seventh multi-way valve 907 and an eighth multi-way valve 908 .

[0047] Among them, the first valve port of the first multi-way valve 901 is connected to the third port, and the second valve port of the first multi-way valve 901 is connected to one end of the fin heat exchanger 3; the first valve port of the second multi-way valve 902 is connected to one end of the throttling device 4, and the second valve port of the fifth multi-way valve 905 is connected to the other end of the fin heat exchanger 3; the first valve port of the third multi-way valve 903 is connected to the first end of the heat exchanger group 6, and the second valve port of the third multi-way valve 903 is connected to the other end of the throttling device 4 and one end of the liquid reservoir 5; the first valve port of the fourth multi-way valve 904 is connected to the second end of the heat exchanger group 6, and the second valve port of the first multi-way valve 901 is connected to the liquid reservoir 5; the first valve port of the fifth multi-way valve 905 is connected to the first port, and the second valve port of the fifth multi-way valve 905 is connected to the third end of the heat exchanger group 6; the first valve port of the sixth multi-way valve 906 is connected to the third end of the heat exchanger group 6; the first valve port of the seventh multi-way valve 907 is connected to the second valve port of the sixth multi-way valve 906, and the second valve port of the seventh multi-way valve 907 is connected to the fourth end of the heat exchanger group 6; the first valve port of the eighth multi-way valve 908 is connected to the outlet of the compressor 2, and the second valve port of the eighth multi-way valve 908 is connected to the second valve port of the sixth multi-way valve 906 and the first valve port of the seventh multi-way valve 907. Thus, the refrigerant circulation flow path is turned on or off by controlling the switch state of the above-mentioned control valve group 9.

[0048] In some embodiments, Figure 1 As shown, the heat exchanger group 6 includes a first heat exchanger 61 and a second heat exchanger 62 arranged in parallel, and the refrigerant circulation flow path includes a cooling flow path and a heating flow path. For controlling the switching state of the control valve group 9 and the switching state of the four-way valve 7 according to the target operation mode, the controller is specifically configured as follows: controlling the switching state of the control valve group 9 to be a first state according to the collaborative mode, and controlling the third port to be connected with the fourth port to conduct the cooling flow path so that the first heat exchanger 61 operates in the cooling mode, and conducting the heating flow path so that the second heat exchanger 62 operates in the heating mode.

[0049] Specifically, the first heat exchanger 61 and the second heat exchanger 62 are respectively arranged in different spaces. For example, the first heat exchanger 61 is arranged in the first space, and the second heat exchanger 62 is arranged in the second space. When a user needs to turn on the heating mode in the second space, and another user needs to turn on the cooling mode in the first space, the air conditioner in the present application operates in a collaborative mode combining the heating mode and the cooling mode. The switch state of the control valve group 9 is controlled to be the first state, and the third port is controlled to be connected with the fourth port to conduct the cooling flow path, so that the first heat exchanger 61 operates in the cooling mode, and the heating flow path is connected, so that the second heat exchanger 62 operates in the heating mode. Therefore, the air conditioner controls the switch state of the control valve group 9 to be the first state, and controls the third port to be connected with the fourth port, so that the air conditioner can operate in the cooling mode and the heating mode at the same time, thereby meeting the needs of the air conditioner user for cooling and heating at the same time.

[0050] In some embodiments, for controlling the switching state of the control valve group 9 and the switching state of the four-way valve 7 according to the target operating mode, the controller is specifically configured to: control the switching state of the control valve group 9 to be the second state according to the collaborative mode, and control the first port to be connected to the fourth port to conduct the refrigeration flow path so that the second heat exchanger 62 operates in the cooling mode, and conduct the heating flow path so that the first heat exchanger 61 operates in the heating mode.

[0051] Specifically, the first heat exchanger 61 and the second heat exchanger 62 are respectively arranged in different spaces. For example, the first heat exchanger 61 is arranged in the first space, and the second heat exchanger 62 is arranged in the second space. When a user needs to turn on the cooling mode in the second space, and another user needs to turn on the heating mode in the first space, the air conditioner in the present application operates in a collaborative mode combining the heating mode and the cooling mode. The switch state of the control valve group 9 is controlled to be the second state, and the third port is controlled to be connected with the fourth port to conduct the cooling flow path, so that the first heat exchanger 61 operates in the cooling mode, and the heating flow path is connected, so that the second heat exchanger 62 operates in the heating mode. Therefore, the air conditioner controls the switch state of the control valve group 9 to be the first state, and controls the third port to be connected with the fourth port, so that the air conditioner can operate in the cooling mode and the heating mode at the same time to meet the needs of different users for the air conditioner.

[0052] In some embodiments, the first end of the first heat exchanger 61 is connected to the first valve port of the fourth multi-way valve 904, the second end of the first heat exchanger 61 is connected to the second valve port of the fifth multi-way valve 905 and the first valve port of the sixth multi-way valve 906, the first end of the second heat exchanger 62 is connected to the first valve port of the third multi-way valve 903, and the second end of the second heat exchanger 62 is connected to the second valve port of the seventh multi-way valve 907.

[0053] In the embodiment, the control valve group 9 further includes: a ninth multi-way valve 909 , a tenth multi-way valve 910 and an eleventh multi-way valve 911 .

[0054] Among them, the first valve port of the ninth multi-way valve 909 is connected to the second end of the second heat exchanger 62 and the second valve port of the seventh multi-way valve 907, and the second valve port of the ninth multi-way valve 909 is connected to one end of the fin heat exchanger 3 and the second valve port of the first multi-way valve 901; the first valve port of the tenth multi-way valve 910 is connected to the first end of the second heat exchanger 62 and the first valve port of the third multi-way valve 903, and the second valve port of the tenth multi-way valve 910 is connected to the first valve port of the second multi-way valve 902 and one end of the throttling device 4; the first valve port of the eleventh multi-way valve 911 is connected to the outlet of the compressor 2, and the second valve port of the eleventh multi-way valve 911 is connected to one end of the fin heat exchanger 3.

[0055] In some embodiments, in the first state, the first valve port of the fourth multi-way valve 904 is connected to the second valve port of the fourth multi-way valve 904, the first valve port of the fifth multi-way valve 905 is connected to the second valve port of the fifth multi-way valve 905, the first valve port of the seventh multi-way valve 907 is connected to the second valve port of the seventh multi-way valve 907, the first valve port of the eighth multi-way valve 908 is connected to the second valve port of the eighth multi-way valve 908, and the first valve port of the tenth multi-way valve 910 is connected to the second valve port of the tenth multi-way valve 910.

[0056] Specifically, the air conditioner 1000 operates in a cooperative mode combining the cooling mode and the heating mode, and the switch state of the control valve group 9 is controlled to be the first state, and the third port C and the fourth port D of the four-way valve 7 are controlled to be connected to conduct the cooling flow path and the heating flow path, that is, the refrigerant is in accordance with Figure 1 The arrow direction shows the circulation flow in the cooling and heating paths. Figure 1The bold black solid line in the figure represents the cooling flow path and the heating flow path after being connected. That is to say, since the first valve port a and the second valve port of the eighth multi-way valve 908 and the seventh multi-way valve 907 are connected, the high-temperature and high-pressure refrigerant discharged from the compressor 2 flows into the second heat exchanger 62 through the eighth multi-way valve 908 and the seventh multi-way valve 907. The second heat exchanger 62 operates in the heating mode, and the high-temperature refrigerant therein exchanges heat with the indoor environment to release heat to the indoor environment, thereby increasing the indoor temperature. The refrigerant after heat exchange flowing out of the second heat exchanger 62 flows into the throttling device 4 through the tenth multi-way valve 910 in turn, and flows into the liquid reservoir 5 after the refrigerant flow is adjusted by the throttling device 4. The refrigerant discharged from the liquid reservoir 5 The refrigerant flows to the first heat exchanger 61 through the fourth multi-way valve 904. The first heat exchanger 61 operates in the cooling mode, and the low-temperature refrigerant therein exchanges heat with the indoor environment to absorb indoor heat, thereby reducing the indoor temperature. The refrigerant after heat exchange flowing out of the first heat exchanger 61 flows into the first port E of the four-way valve 7 through the fifth multi-way valve 905 in turn, and then flows into the vapor-liquid separator 1 through the second port S of the four-way valve 7. The vapor-liquid separator 1 separates the vapor and liquid of the refrigerant and then flows back to the compressor 2. Therefore, by controlling the switch state of the control valve group 9 to be the first state, and controlling the third port C of the four-way valve 7 to be connected to the fourth port D, the simultaneous heating and cooling functions are realized.

[0057] Alternatively, in the first state, the first valve port of the fourth multi-way valve 904 is connected to the second valve port of the fourth multi-way valve 904, the first valve port of the fifth multi-way valve 905 is connected to the second valve port of the fifth multi-way valve 905, the first valve port of the ninth multi-way valve 909 is connected to the second valve port of the ninth multi-way valve 909, the first valve port of the tenth multi-way valve 910 is connected to the second valve port of the tenth multi-way valve 910, and the first valve port of the eleventh multi-way valve 911 is connected to the second valve port of the eleventh multi-way valve 911.

[0058] Specifically, the air conditioner 1000 operates in a cooperative mode combining the heating mode and the cooling mode, controls the switch state of the control valve group 9 to be the first state, and controls the third port C of the four-way valve 7 to be connected to the fourth port D to conduct the cooling flow path and the heating flow path, that is, the refrigerant is in accordance with Figure 2 The arrow direction shows the circulation flow in the cooling and heating paths. Figure 2The bold black solid line in the figure is the cooling flow path and the heating flow path after being connected, that is, the high-temperature and high-pressure refrigerant discharged from the compressor 2 flows into the second heat exchanger 62 through the eleventh multi-way valve 911 and the ninth multi-way valve 909, and the second heat exchanger 62 operates in the heating mode, in which the high-temperature refrigerant exchanges heat with the indoor environment to release heat to the indoor environment, thereby increasing the indoor temperature, and the refrigerant flowing out of the second heat exchanger 62 after the heat exchange passes through the tenth multi-way valve 910, the throttling device 4 and the liquid storage device 5 in turn into the first heat exchanger 61, and the first heat exchanger 61 operates in the cooling mode, in which the low-temperature refrigerant exchanges heat with the indoor environment. Heat exchange is carried out to absorb indoor heat, thereby reducing the indoor temperature. The refrigerant after heat exchange flowing out of the first heat exchanger 61 flows into the first port E of the four-way valve 7 through the fifth multi-way valve 905, and then flows into the second port S of the four-way valve 7 from the first port E of the four-way valve 7, and flows into the vapor-liquid separator 1 through the second port S of the four-way valve 7. The vapor-liquid separator 1 separates the vapor and liquid of the refrigerant and then flows back to the compressor 2. Therefore, by controlling the switch state of the control valve group 9 to be the first state, and controlling the first port E of the four-way valve 7 to be connected to the fourth port D, the simultaneous heating and cooling functions are realized.

[0059] In some embodiments, in the second state, the first valve port of the first multi-way valve 901 is connected to the second valve port of the first multi-way valve 901, the first valve port of the fourth multi-way valve 904 is connected to the second valve port of the fourth multi-way valve 904, the first valve port of the sixth multi-way valve 906 is connected to the second valve port of the sixth multi-way valve 906, the first valve port of the eighth multi-way valve 908 is connected to the second valve port of the eighth multi-way valve 908, the first valve port of the ninth multi-way valve 909 is connected to the second valve port of the ninth multi-way valve 909, and the first valve port of the tenth multi-way valve 910 is connected to the second valve port of the tenth multi-way valve 910.

[0060] Specifically, the air conditioner 1000 operates in a cooperative mode combining the heating mode and the cooling mode, controls the switch state of the control valve group 9 to be the second state, and controls the first port E of the four-way valve 7 to be connected to the fourth port D to conduct the cooling flow path and the heating flow path, that is, the refrigerant is in accordance with Figure 3 The arrow direction shows the circulation flow in the cooling and heating paths. Figure 3The bold black solid line in the figure is the cooling flow path and the heating flow path after being connected. Since the first valve port a and the second valve port b of the eighth multi-way valve 908 are connected, and the first valve port a and the second valve port b of the sixth multi-way valve 906 are connected, the high-temperature and high-pressure refrigerant discharged from the compressor 2 flows into the first heat exchanger 61 through the eighth multi-way valve 908 and the sixth multi-way valve 906. The first heat exchanger 61 operates in the heating mode, and the high-temperature refrigerant therein exchanges heat with the indoor environment to release heat to the indoor environment, thereby increasing the indoor temperature. The refrigerant flowing out of the first heat exchanger 61 after the heat exchange is stored in turn through the liquid storage device 5. Since the first valve port a and the second valve port b of the tenth multi-way valve 910 are connected, the refrigerant discharged from the liquid storage device 5 is adjusted by the throttling device 4 for refrigerant flow, and then flows into the second heat exchanger 62 through the tenth multi-way valve 910. The second heat exchanger 62 operates in the cooling mode, and the low-temperature refrigerant therein exchanges heat with the indoor environment to absorb indoor heat, thereby lowering the indoor temperature. Since the first valve port a and the second valve port b of the ninth multi-way valve 909 are connected, and the first valve port a and the second valve port b of the first multi-way valve 901 are connected, the refrigerant after heat exchange flowing out of the second heat exchanger 62 flows into the first multi-way valve 901 through the ninth multi-way valve 909, and then flows from the first multi-way valve 901 into the third port C of the four-way valve 7, and flows from the second port S of the four-way valve 7 into the vapor-liquid separator 1. The vapor-liquid separator 1 separates the vapor and liquid of the refrigerant and then flows back to the compressor 2. Therefore, by controlling the switch state of the control valve group 9 to be the second state, and controlling the first port E of the four-way valve 7 to be connected to the fourth port D, the simultaneous heating and cooling functions are realized.

[0061] In some embodiments, the target operation mode is the cooling mode, and the switch state of the control valve group 9 is controlled according to the cooling mode, and the third port C and the fourth port D of the four-way valve 7 are controlled to be connected to conduct the cooling flow path, so that the high-temperature and high-pressure refrigerant discharged by the compressor 2 circulates in the cooling flow path, that is, according to Figure 4 The direction of the arrow shown is in the refrigeration flow circuit, where Figure 5The bold black solid line in the figure is the refrigeration flow path, that is, since the fourth port D and the third port C of the four-way valve 7 are connected, the high-temperature and high-pressure refrigerant discharged by the compressor 2 flows into the domestic water tank 8 and then flows to the fourth port D of the four-way valve 7. Since the first valve port a and the second valve port b of the first multi-way valve 901 are connected, the refrigerant can flow into the first valve port a of the first multi-way valve 901 through the third port C of the four-way valve 7, and flow into the fin heat exchanger 3 through the second valve port b of the first multi-way valve 901. The fin heat exchanger 3 exchanges heat between the high-temperature and high-pressure refrigerant and the outdoor environment, that is, absorbs the heat of the high-temperature and high-pressure refrigerant to release it to the outdoor environment. The heat is released from the environment. Since the first valve port a and the second valve port b of the second multi-way valve 902 are connected, the refrigerant after releasing the heat can flow into the throttling device 4 through the second multi-way valve 902 for refrigerant flow regulation. Since the first valve port a and the second valve port b of the third multi-way valve 903 are connected, a part of the refrigerant flows into the second heat exchanger 62 arranged on a refrigerant branch line through the third multi-way valve 903. The low-temperature refrigerant in the second heat exchanger 62 exchanges heat with the indoor environment to absorb indoor heat, thereby reducing the indoor temperature. Due to the seventh multi-way valve 907, the sixth multi-way valve 906 and the fifth multi-way valve 905 The first valve port a and the second valve port b are connected. The refrigerant after heat exchange flowing out of the second heat exchanger 62 flows into the first port E of the four-way valve 7 through the seventh multi-way valve 907, the sixth multi-way valve 906 and the fifth multi-way valve 905 in sequence, and then flows into the vapor-liquid separator 1 through the second port S of the four-way valve 7. The vapor-liquid separator 1 separates the vapor and liquid of the refrigerant and then flows back to the compressor 2. Another part of the refrigerant flows into the liquid storage 5 for storage. The refrigerant discharged from the liquid storage 5 flows from the fourth multi-way valve 904 into the first heat exchanger 61 set on another refrigerant branch. The low-temperature refrigerant in the first heat exchanger 61 is heated to room temperature. Heat exchange is performed to absorb indoor heat, thereby lowering the indoor temperature. Heat exchange is performed with the indoor environment through the heat exchangers on the two refrigerant branches to lower the indoor temperature. The refrigerant after heat exchange flowing out of the heat exchanger flows into the first port of the four-way valve 7 through the fifth multi-way valve 905, and then flows into the vapor-liquid separator 1 through the second port S of the four-way valve 7. The vapor-liquid separator 1 separates the vapor and liquid of the refrigerant and then flows back to the compressor 2. The cooling mode is realized by controlling the switching state of the control valve group 9 and controlling the connection between the third port C and the fourth port D of the four-way valve 7, thereby meeting the user's cooling needs.

[0062] In some embodiments, the target operation mode is the cooling mode, and the switch state of the control valve group 9 is controlled according to the cooling mode, and the third port C and the fourth port D of the four-way valve 7 are controlled to be connected to conduct the cooling flow path, so that the high-temperature and high-pressure refrigerant discharged by the compressor 2 circulates in the cooling flow path, that is, according to Figure 6 The direction of the arrow shown is in the refrigeration flow circuit, where Figure 7The bold black solid line in the middle is the refrigeration flow path, that is, since the first valve port a and the second valve port b of the eleventh multi-way valve 911 are connected, the high-temperature and high-pressure refrigerant discharged from the compressor 2 can flow into the fin heat exchanger 3 through the eleventh multi-way valve 911, and the fin heat exchanger 3 then exchanges heat between the high-temperature and high-pressure refrigerant and the outdoor environment, that is, absorbs the heat of the high-temperature and high-pressure refrigerant to release the heat to the outdoor environment. Since the first valve port a and the second valve port b of the second multi-way valve 902 are connected, the refrigerant after releasing the heat flows into the throttling device 4 through the second multi-way valve 902 to control the refrigerant flow rate. After adjustment, since the first valve port a and the second valve port b of the third multi-way valve 903 are connected, a part of the refrigerant flows into the second heat exchanger 62 arranged on a refrigerant branch through the third multi-way valve 903, and the low-temperature refrigerant in the second heat exchanger 62 exchanges heat with the indoor environment to absorb indoor heat, thereby reducing the indoor temperature. Since the first valve port a and the second valve port b of the sixth multi-way valve 906, the seventh multi-way valve 907 and the fifth multi-way valve 905 are connected, the refrigerant after heat exchange flowing out of the heat exchanger can pass through the sixth multi-way valve 906, the seventh multi-way valve 907 and the fifth multi-way valve 905. The multi-way valve 905 flows into the first port E of the four-way valve 7, and then flows into the vapor-liquid separator 1 through the second port S of the four-way valve 7. The vapor-liquid separator 1 separates the vapor and liquid of the refrigerant and then flows back to the compressor 2. The other part of the refrigerant flows into the liquid reservoir 5 to be stored. Since the first valve port a and the second valve port b of the fourth multi-way valve 904 are connected, the refrigerant discharged from the liquid reservoir 5 can flow from the fourth multi-way valve 904 into the first heat exchanger 61 set on another refrigerant branch. The low-temperature refrigerant in the first heat exchanger 61 exchanges heat with the indoor environment to absorb indoor heat, thereby reducing The indoor temperature is thereby exchanged with the indoor environment through the heat exchangers on the two refrigerant branches, thereby lowering the indoor temperature. The refrigerant after heat exchange flowing out of the heat exchanger flows into the first port E of the four-way valve 7 through the fifth multi-way valve 905, and then flows into the vapor-liquid separator 1 through the second port S of the four-way valve 7. The vapor-liquid separator 1 then separates the vapor and liquid of the refrigerant and then flows back to the compressor 2. The refrigeration mode is achieved by controlling the switching state of the control valve group 9 and controlling the connection between the third port C and the fourth port D of the four-way valve 7, thereby meeting the user's refrigeration needs.

[0063] In some embodiments, the target operation mode is the heating mode, and the switch state of the control valve group 9 is controlled according to the heating mode, and the first port E of the four-way valve 7 is controlled to be connected with the fourth port D to conduct the heating flow path, so that the high-temperature and high-pressure refrigerant discharged from the compressor 2 circulates in the heating flow path, that is, according to Figure 8 The direction of the arrow shown is in the heating flow path, where Fig. 9The bold black solid line in the middle is the heating flow path, that is, since the first valve port a and the second valve port b of the ninth multi-way valve 909, the seventh multi-way valve 907 and the sixth multi-way valve 906 are connected, the high-temperature and high-pressure refrigerant discharged from the compressor 2 flows through the eighth multi-way valve 908, and a part of the refrigerant flows into a heat exchanger arranged on a refrigerant branch through the seventh multi-way valve 907. The high-temperature refrigerant in the heat exchanger exchanges heat with the indoor environment to release heat to the indoor environment, thereby increasing the indoor temperature. The refrigerant flowing out of the heat exchanger after the heat exchange flows into the throttling device 4 through the third multi-way valve 903, and the other part of the refrigerant flows into the heat exchanger arranged on another refrigerant branch through the sixth multi-way valve 906. The high-temperature refrigerant in the heat exchanger exchanges heat with the indoor environment to release heat to the indoor environment, thereby increasing the indoor temperature. The refrigerant flowing out of the heat exchanger after the heat exchange flows into the liquid storage 5 to be stored, and the refrigerant discharged from the liquid storage 5 flows into the throttling device 4 , thereby performing heat exchange with the indoor environment through the heat exchangers on the two refrigerant branches, so that the indoor temperature is increased. After the refrigerant passes through the throttling device 4 and the refrigerant flow is adjusted, since the first valve port a and the second valve port b of the second multi-way valve 902 are connected, it can flow into the fin heat exchanger 3 through the second multi-way valve 902. The fin heat exchanger 3 exchanges heat between the low-temperature refrigerant and the outdoor environment, that is, the heat of the low-temperature refrigerant absorbs the heat of the outdoor environment. The refrigerant after absorbing the heat flows into the third port C of the four-way valve 7 under the connection between the first valve port a and the second valve port b of the first multi-way valve 901, and then flows into the vapor-liquid separator 1 through the second port S of the four-way valve 7. The vapor-liquid separator 1 separates the vapor and liquid of the refrigerant and then flows back to the compressor 2. Therefore, the heating mode is completed by controlling the switching state of the control valve group 9 and controlling the first port E of the four-way valve 7 to be connected with the fourth port D, thereby meeting the heating needs of the user.

[0064] In the embodiment, the multi-way valve may be a multi-directional valve body such as a four-way valve 7 or a three-way valve, which is not limited thereto.

[0065] In the embodiment, the heat exchange tube of the domestic water tank 8 is in the shape of a coil, which is wound around the outside of the metal inner liner of the domestic water tank 8. There is thermal grease between the heat exchange tube and the metal inner liner, and the thermal grease can enhance heat transfer.

[0066] In the embodiment, except for the compressor 2, the domestic water tank 8, the four-way valve 7, and the vapor-liquid separator 1, the multi-way valve and the heat exchanger have no directionality and can be connected in any direction.

[0067] In an embodiment, the multi-way valve in the present application can change the flow direction of the refrigerant in the entire refrigeration system by opening and closing.

[0068] A second aspect of the present invention provides a method for controlling an air conditioner, which is used in the air conditioner of the above embodiment. Fig.10 As shown, the control method includes: step S1 to step S3.

[0069] Step S1, obtaining a target operation mode of the air conditioner, wherein the target operation mode at least includes a coordinated mode combining a heating mode and a cooling mode.

[0070] Specifically, the user can send control instructions about the operating mode to the air conditioner through the remote control, the air conditioning application in the mobile terminal or the control panel on the air conditioner body by language, gestures and other operating methods. The air conditioner receives the control instructions about the operating mode, and the controller obtains the target operating mode of the air conditioner. For example, the target operating mode of the air conditioner is a collaborative mode combining the heating mode and the cooling mode, or a heating mode or a cooling mode, and there is no restriction on this.

[0071] Step S2, determining that the target operation mode of the air conditioner is a cooperative mode.

[0072] Exemplarily, if the air conditioner receives a control instruction of the cooperative mode, the controller acquires that the target operation mode of the air conditioner is the cooperative mode.

[0073] Step S3, controlling the switch state of the control valve group and the switch state of the four-way valve according to the target operation mode to control the operation of the heat exchanger group.

[0074] Specifically, the existing air conditioner cannot operate in cooling mode and heating mode at the same time to meet the needs of air conditioner users for both cooling and heating. In order to solve this problem, in the present application, the switching state of the control valve group and the switching state of the four-way valve are controlled according to the target operation mode, so that the air conditioner can operate in cooling mode and heating mode at the same time, thereby meeting the needs of air conditioner users for both cooling and heating. That is to say, the heat exchanger groups are arranged in different spaces. When some users need to turn on the heating mode in a certain space, and other users need to turn on the cooling mode in another space, the target operation mode of the air conditioner is a collaborative mode combining the heating mode and the cooling mode. Then, the switching state of the control valve group and the switching state of the four-way valve are controlled according to the target operation mode to control a part of the heat exchangers in the heat exchanger group to operate in cooling mode and control another part of the heat exchangers in the heat exchanger group to operate in heating mode, so that the air conditioner can operate in cooling mode and heating mode at the same time, thereby meeting the needs of air conditioner users for both cooling and heating.

[0075] In addition, when the target operation mode of the air conditioner is heating mode or cooling mode, the switching state of the control valve group and the switching state of the four-way valve are controlled according to the target operation mode in the present application, thereby realizing the cooling or heating function.

[0076] According to the control method of the air conditioner according to the embodiment of the present invention, when the target operating mode is a collaborative mode combining the heating mode and the cooling mode, by controlling the switching state of the control valve group and the switching state of the four-way valve, different heat exchangers in the heat exchanger group can operate in the cooling mode and the heating mode at the same time, thereby meeting the needs of the user of the air conditioner for both cooling and heating.

[0077] In some embodiments, the heat exchanger group includes a first heat exchanger and a second heat exchanger arranged in parallel, and controls the switching state of the control valve group and the switching state of the four-way valve according to the target operating mode, including: controlling the switching state of the control valve group to a first state according to the collaborative mode, and controlling the third port to be connected to the fourth port to control the first heat exchanger to operate in a cooling mode, and controlling the second heat exchanger to operate in a heating mode.

[0078] Specifically, the first heat exchanger and the second heat exchanger are respectively arranged in different spaces. For example, the first heat exchanger is arranged in the first space, and the second heat exchanger is arranged in the second space. When a user needs to turn on the heating mode in the second space, and another user needs to turn on the cooling mode in the first space, the air conditioner in the present application operates in a collaborative mode combining the heating mode and the cooling mode. The switch state of the control valve group is controlled to be the first state, and the third port is controlled to be connected with the fourth port to conduct the cooling flow path, so that the first heat exchanger operates in the cooling mode, and the heating flow path is connected, so that the second heat exchanger operates in the heating mode. Therefore, the air conditioner controls the switch state of the control valve group to be the first state, and controls the third port to be connected with the fourth port, so that the air conditioner can operate in the cooling mode and the heating mode at the same time, thereby meeting the needs of the air conditioner user for cooling and heating at the same time.

[0079] In some embodiments, controlling the switching state of the control valve group and the switching state of the four-way valve according to the target operating mode also includes: controlling the switching state of the control valve group to a second state according to the collaborative mode, and controlling the first port to be connected to the fourth port to control the second heat exchanger to operate in a cooling mode, and controlling the first heat exchanger to operate in a heating mode.

[0080] Specifically, the first heat exchanger and the second heat exchanger are respectively arranged in different spaces. For example, the first heat exchanger is arranged in the first space, and the second heat exchanger is arranged in the second space. When a user needs to turn on the cooling mode in the second space, and another user needs to turn on the heating mode in the first space, the air conditioner in the present application operates in a collaborative mode combining the heating mode and the cooling mode. The switch state of the control valve group is controlled to be the second state, and the third port is controlled to be connected with the fourth port to conduct the cooling flow path, so that the first heat exchanger operates in the cooling mode, and the heating flow path is connected, so that the second heat exchanger operates in the heating mode. Therefore, the air conditioner controls the switch state of the control valve group to be the first state, and controls the third port to be connected with the fourth port, so that the air conditioner can operate in the cooling mode and the heating mode at the same time to meet the needs of different users for the air conditioner.
