Embodiment 1

[0062] This embodiment provides an air conditioner heat exchange structure, the air conditioner external unit includes: at least two heat exchange modules, the series-parallel relationship between the at least two heat exchange modules can be adjusted, and the operating state of each heat exchange module can be adjusted. The at least two heat exchange modules constitute an outdoor heat exchange system. 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 external unit can be determined according to the operation mode of the air-conditioning system. ), and by controlling the corresponding devices to achieve the above connection relationship and operating status, thereby improving the heat transfer effect, ensuring the high efficiency of the operating mode, meeting the comfort needs o...

Embodiment 2

[0083] This embodiment provides an air conditioning system, comprising: at least one air conditioner internal unit and at least one air conditioner external unit, the air conditioner external unit or the air conditioner internal unit includes the above-mentioned air conditioner heat exchange structure.

[0084] In this embodiment, at least two heat exchange modules are installed in the air conditioner external unit. By controlling the corresponding three-position on-off valve and throttling device, the connection relationship between the above-mentioned at least two heat exchange modules can be changed, and the heat exchange modules can be cooled, The heating state changes, so as to cooperate with the air conditioner internal unit or external unit to ensure efficient operation in different operating modes and meet user comfort needs, while improving unit energy efficiency.

Embodiment 3

[0089] In the third preferred embodiment of the present invention, there is also provided a method for controlling an air-conditioning system, the external unit of the air-conditioning system includes the heat exchange structure of the air conditioner in the first embodiment above. Specifically, Figure 8 An alternative flowchart showing the method, such as Figure 8 As shown, the method includes the following steps S802-S806:

[0090] S802: Detect the operation mode of the air conditioning system;

[0091] S804: Determine the connection relationship and operating status of the heat exchange modules in the air conditioner external unit according to the operating mode;

[0092] S806: Control the three-position on-off valve and the throttling device to perform corresponding operations according to the connection relationship and the operating state.

[0093] In this embodiment, at least two heat exchange modules are installed in the air conditioner external unit. By controlli...

Abstract

The invention discloses an air conditioner heat exchange structure, an air conditioner system, a control method of the air conditioner system and an air conditioner outdoor unit. The air conditioner heat exchange structure comprises at least two heat exchange modules, and the series-parallel connection relation and the operation state of the at least two heat exchange modules can be adjusted. For the situation that two heat exchange modules are included, the first end of the first heat exchange module is connected to the first end of the second heat exchange module through a first three-position on-off valve, and the first end of the first heat exchange module is further connected to the second end of the second heat exchange module through a first throttling device; the second end of the first heat exchange module is connected to the second end of the second heat exchange module through a second three-position on-off valve, and the second end of the first heat exchange module is further connected to the first end of the second heat exchange module through a second throttling device. The at least two heat exchange modules are arranged, the connection relation and the operation state of the heat exchange modules are changed by controlling the three-position on-off valves and the throttling devices, and efficient operation in different operation modes is guaranteed. The using comfort and energy efficiency of an air conditioner are improved in cooperation with an indoor unit.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner heat exchange structure, an air conditioner system and a control method thereof, and an air conditioner external unit. Background technique [0002] At present, the structure of the air-conditioning system is relatively fixed. Generally, an outdoor heat exchanger is installed in the outdoor unit of the air-conditioner, and the heat exchange method is fixed. For various heat exchange needs, it is difficult for a single heat exchanger to meet the user's cooling or heating needs. Specifically, the following problems exist: [0003] (1) During cooling and heating, the state of the refrigerant in the heat exchanger is different. At this time, the pressure drop of the heat exchanger and the heat exchange system are different. The fixed flow path of the heat exchanger cannot take into account the high efficiency of cooling and heating at the same time; [00...
