As shown in fig. 1, in an air conditioning system 100 provided in an embodiment of the present application, the air conditioning system 100 includes a compressor 101, a four-way reversing valve 102, an outdoor heat exchanger 103, a throttling device 104, a first indoor heat exchanger 105, a second indoor heat exchanger 106, a first valve 107, a second valve 108, a third valve 109, a fourth valve 110, a fifth valve 111, a sixth valve 112, a seventh valve 113, and an eighth valve 114.

The four-way selector valve 102 includes: a first end, a second end, a third end, and a fourth end. The first end is shown in figure 1 with the arabic numeral 1. The second end is shown in figure 1 with the arabic numeral 2. The third end is shown in figure 1 with the arabic numeral 3. The fourth end is shown in figure 1 with the arabic numeral 4.

A first end of the four-way selector valve 102 is connected to an exhaust port of the compressor 101, and a third end of the four-way selector valve 102 is connected to an intake port of the compressor 101.

The fourth end of the four-way reversing valve 102 is connected with the first end of the second indoor heat exchanger 106 through a first valve 107; and a first end of the first indoor heat exchanger 105 through a third valve 109.

The second end of the four-way reversing valve 102 is connected with the first end of the outdoor heat exchanger 103 through a seventh valve 113; and a first end of the first indoor heat exchanger 105 through a fifth valve 111.

A second end of the outdoor heat exchanger 103 is connected to a first end of the throttling device 104 through an eighth valve 114.

The refrigerant described in the embodiments of the present application may be any one of freon R22, freon R410A, and freon R32, or may be another refrigerant applied to an air conditioning system, and the present application is not limited thereto.

The four-way reversing valve 102 includes two states of conduction, a first state of conduction and a second state of conduction. Under the condition that the four-way reversing valve 102 is in the first conduction state, the first end of the four-way reversing valve 102 is conducted with the second end of the four-way reversing valve 102, and the third end of the four-way reversing valve 102 is conducted with the fourth end of the four-way reversing valve 102; when the four-way reversing valve 102 is in the second conducting state, the first end of the four-way reversing valve 102 and the fourth end of the four-way reversing valve 102 are conducted, and the second end of the four-way reversing valve 102 and the third end of the four-way reversing valve 102 are conducted.

In one possible design, the on state of the four-way reversing valve 102 may be varied based on the on/off state of the four-way reversing valve 102. For example, the four-way reversing valve 102 is in a first conducting state when the four-way reversing valve 102 is de-energized; when the four-way reversing valve 102 is energized, the four-way reversing valve 102 is in the second conducting state.

The outdoor heat exchanger 103 exchanges heat between the refrigerant and the outside to change the state of the refrigerant.

For example, in a cold air (or cold water) mode of the air conditioning system, the high-temperature and high-pressure gaseous refrigerant is liquefied and releases heat in the outdoor heat exchanger 103, and a low-temperature and high-pressure liquid refrigerant is formed. The air temperature in the outdoor heat exchanger 103 rises to form hot air. The outdoor heat exchanger 103 exchanges heat between the hot air inside and the air in the outdoor environment.

In the hot air (or hot water) mode of the air conditioner, the refrigerant in the low-temperature low-pressure saturated state is vaporized and absorbs heat in the outdoor heat exchanger 103, and a low-temperature low-pressure gaseous refrigerant is formed. The air temperature in the outdoor heat exchanger 103 decreases to form cold air. The outdoor heat exchanger 103 discharges the cold air inside to the outside for the purpose of heat exchange with the outside.

The throttling device 104 mainly functions to depressurize the refrigerant. And the liquid refrigerant is converted into a saturated refrigerant. For example, a low-temperature high-pressure liquid refrigerant is depressurized to form a low-temperature low-pressure saturated refrigerant. The throttle device 104 may be any one of an electronic expansion valve, a capillary tube, a throttle valve, and a thermal expansion valve, which is not limited in the present application.

The first indoor heat exchanger 105 is used to provide cold or hot wind. The first indoor heat exchanger 105 may be connected to the air conditioning system 100 through an air stop valve and a liquid stop valve, and the first indoor heat exchanger 105 may be any one of a wall-mounted air conditioner indoor unit, a floor-type air conditioner indoor unit, a duct-type air conditioner indoor unit, a central air conditioner, and a heating and ventilation system.

The second indoor heat exchanger 106 is used to supply cold water or hot water. The second indoor heat exchanger 106 is connected to a water supply system of a user. The user's water supply system injects water into the second indoor heat exchanger 106 through the water inlet valve. The second indoor heat exchanger 106 supplies cold or hot water to a water supply system of a user through a water outlet valve. Illustratively, the second indoor heat exchanger 106 may be any one of a plate heat exchanger, a shell-and-tube heat exchanger, and a coaxial heat exchanger. The water supply system of the user can be any one of a floor heating system, a fan coil, a radiator and an evaporator.

The first valve 107 to the eighth valve 114 are used for controlling the flow direction of the refrigerant in the air conditioning system. For example, when the first valve 107 is in the open state, the first end of the second indoor heat exchanger 106 is in communication with the fourth end of the four-way reversing valve 102. The refrigerant flows from the first end of the second indoor heat exchanger 106 to the fourth end of the four-way reversing valve 102, or from the fourth end of the four-way reversing valve 102 to the first end of the second indoor heat exchanger 106.

The first to eighth valves 107 to 114 described in the embodiment of the present application may be solenoid valves.

Based on the above technical solution, the air conditioning system, the control method and the control device provided by the present application include: the air conditioner comprises a compressor 101, a four-way reversing valve 102, an outdoor heat exchanger 103, a throttling device 104, a first indoor heat exchanger 105, a second indoor heat exchanger 106, a first valve 107, a second valve 108, a third valve 109, a fourth valve 110, a fifth valve 111, a sixth valve 112, a seventh valve 113 and an eighth valve 114. The air conditioning system may control the flow direction of the refrigerant by controlling the on state of the four-way selector valve 102 and the on/off states of the first through eighth valves 107 through 114. Different refrigerant flowing directions can enable the air conditioning system to realize different working modes. Therefore, the air conditioning system, the control method and the control device provided by the application can provide various working modes of the air conditioning system, and further meet the diversified demands of users.

Based on the air conditioning system 100 shown in fig. 1, as shown in fig. 2, the outdoor heat exchanger 103 further includes an air supply system 1031; the third end of the second indoor heat exchanger 106 is further connected with a water outlet valve 1061, and the fourth end of the second indoor heat exchanger 106 is further connected with a water inlet valve 1062. Both ends of the first indoor heat exchanger 105 further include an air cut-off valve 115 and a liquid cut-off valve 116.

The air supply system 1031 is used for enhancing the heat convection between the outdoor heat exchanger 103 and the outdoor air. For example, when the air conditioning system 100 cools, the refrigerant releases heat at the outdoor heat exchanger 103, the temperature of the air in the outdoor heat exchanger 103 rises, and the air with higher temperature in the outdoor heat exchanger 103 can be quickly discharged to the outside through the air supply system 1031, so that the air with lower outside temperature enters the outdoor heat exchanger 103. The water outlet valve 1061 is used to discharge the water stored in the second indoor heat exchanger 106; the water inlet valve 1062 is used to inject water into the second indoor heat exchanger 106.

In the second indoor heat exchanger 106, the refrigerant is liquefied to release heat so as to raise the temperature of water in the second indoor heat exchanger 106, thereby achieving the purpose of providing hot water for users; or the temperature of the water in the second indoor heat exchanger 106 is lowered by absorbing heat through vaporization, thereby achieving the purpose of providing cold water for users.

In a possible design, when the first indoor heat exchanger 105 is a large central air conditioning, heating and ventilating system, both ends of the first indoor heat exchanger 105 further include an air stop valve 115 and a liquid stop valve 116.

The air shutoff valve 115 is used to couple a first end of the first indoor heat exchanger 105 into the air conditioning system, and the liquid shutoff valve 116 is used to couple a second end of the first indoor heat exchanger 105 into the air conditioning system.

As shown in fig. 3, an embodiment of the present application provides a control method, which is applied to the air conditioning system shown in fig. 1 or fig. 2, where the air conditioning system further includes a control device. The method comprises the following steps:

s301, the control device receives the working mode indication information.

In one possible design, the operating mode indication information may be generated by a remote control/control panel of the air conditioning system; alternatively, the operation mode indication information may be generated by the air conditioning system itself.

The description will be given by taking an example in which the operation mode instruction information is generated by an air conditioner remote controller, and the air conditioner remote controller is provided with keys corresponding to the respective operation modes. For example, a cold air working mode key corresponding to the cold air working mode is arranged on the air conditioner remote controller. When the remote controller detects that the cold air working mode key is pressed, the remote controller generates cold air working mode indicating information and sends the cold air working mode indicating information to the air conditioning system. And after receiving the cold air working mode indication information, the air conditioning system sends the cold air working mode indication information to the control device, and the control device receives the cold air working mode indication information.

Taking the working mode indication information generated by the air conditioning system as an example, the air conditioning system can monitor the ambient temperature, and can switch from the hot air working mode to the cold air working mode under the condition that the ambient temperature is higher than the preset temperature; or, the air conditioning system may be switched from the cold air operation mode to the hot air operation mode when the ambient temperature is less than the preset temperature.

And S302, the control device controls the air conditioning system to use the working mode corresponding to the working mode indication information according to the received working mode indication information.

As a possible implementation manner, the control device controls the on-off states of the first to eighth valves 107 to 114 according to the operation mode indication information; the on-state of the four-way reversing valve 102; and the working states of the compressor 101, the outdoor heat exchanger 103, the throttling device 104, the first indoor heat exchanger 105 and the second indoor heat exchanger 106, so as to achieve the purpose of controlling the air conditioning system to use the working mode corresponding to the working mode indication information.

Based on the control method shown in fig. 3, the control device may control the on-off states of the first to eighth valves 107 to 114; the on-state of the four-way reversing valve 102; and the operating states of the compressor 101, the outdoor heat exchanger 103, the throttle device 104, the first indoor heat exchanger 105, and the second indoor heat exchanger 106; the working mode of the air conditioning system is adjusted, so that the air conditioning system can realize eight operation modes including a cold air mode, a cold water mode, a hot air mode, a hot water mode, a cold air and cold water mode, a hot air and hot water mode, a hot water and cold air mode and a cold water and hot air mode, the application scene of the air conditioner is greatly improved, and various requirements of users on the air conditioner are met.
