Embodiment 1
[0059] This embodiment provides a heat exchange structure for an air conditioner. The inner unit of the air conditioner includes: at least two heat exchange modules, and the series-parallel relationship between the at least two heat exchange modules can be adjusted. Specifically, the connection relationship (for example, series and / or parallel relationship) and the operation status (for example, cooling, heating, and stop operation) of the above-mentioned at least two heat exchange modules in the air-conditioning indoor unit can be determined according to the operation mode of the air-conditioning system. ), and by controlling the corresponding devices to realize the above-mentioned connection relationship and operating state, so as to ensure the high efficiency of the operating mode, meet the user's comfort requirements, and improve the energy efficiency of the unit.
[0060] The description of specific implementations below takes the heat exchange structure located in the ind...
Embodiment 2
[0071] This embodiment provides an air conditioning system, including: at least one air conditioner internal unit and at least one air conditioner external unit, the air conditioner internal unit or the external unit includes the air conditioner heat exchange structure described in Embodiment 1 above. exist Figure 2 to Figure 8 Among them, the indoor side is the air conditioner internal unit, and the outdoor side is the air conditioner external unit.
[0072] In this embodiment, at least two heat exchange modules are installed in the air conditioner internal unit. For the case of two heat exchange modules, by controlling the first throttling device, the second throttling device, the third valve and the third throttling device, the two heat exchange modules can be changed. The connection relationship between each heat exchange module can be realized, and the cooling and heating state changes of the heat exchange module can be realized, so as to cooperate with the external unit...
Embodiment 3
[0078] In the third preferred embodiment of the present invention, a method for controlling an air-conditioning system is also provided, and the internal unit of the air-conditioning system includes the air-conditioning heat exchange structure in the first embodiment above. Specifically, Figure 9 An alternative flowchart showing the method, such as Figure 9 As shown, the method includes the following steps S902-S906:
[0079] S902: Detect the operation mode of the air conditioning system;
[0080] S904: Determine the connection relationship and operating status of the first heat exchange module and the second heat exchange module according to the operation mode;
[0081] S906: Control the first throttling device, the second throttling device, the third valve, the third throttling device, and the fourth throttling device to perform corresponding operations according to the connection relationship and the operating state.
[0082] In the above embodiment, at least two heat ...
