Embodiment Construction
[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0019] Such as figure 1 and figure 2 As shown, an air conditioning system provided by an embodiment of the present invention includes a compressor 1 and a four-way valve, and also includes a first heat exchanger 31 that can be used as an evaporator and a condenser, and a second heat exchanger that can be used as an evaporator and a condenser. Heat exchanger 32, the four-way valve includes a first four-way valve 21 and a second four-way valve 22, specifically, the first heat exchanger 31 and the second heat exchanger 32 can be switched to evaporation by controlling each four-way valve condenser o...

The invention belongs to the technical field of air conditioners and discloses an air conditioner system and a control method thereof. The air conditioner system comprises a compressor, four-way valves, a first heat exchanger and a second heat exchanger. The four-way valves include a first four-way valve and a second four-way valve. The compressor is connected with the heat exchangers through the four-way valves, and therefore, the heat exchangers are converted into evaporators or condensers according to the actual needs. The air conditioner system further comprises a first fan adjacent to the first heat exchanger and an electronic control box. The control method includes that in the case that the air conditioner system runs in the heating mode or hybrid mode or cooling mode, the first heat exchanger is converted into the evaporator. The air conditioner system and the control method thereof have the advantages that temperature of electronic control elements, particularly a frequency conversion module, is effectively decreased to prevent the elements in the electronic control box from damage caused by excess temperature, product reliability is high, and service life is long.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner system and a control method thereof. Background technique [0002] Most of the current air-conditioning systems use outdoor fans to dissipate the temperature of the electronic control and frequency conversion modules, but for the three-pipe air-conditioning system with two blend mode. When the system operates in hybrid mode and outdoor low-temperature pure cooling mode, the heat exchanger on the same side as the electric control box acts as a condenser and the system requires the outdoor fan to stop, at this time, the electric control components in the outdoor unit, especially the frequency conversion module The heating will exceed the standard requirements, and long-term operation will cause damage to electrical components and low product reliability. Contents of the invention [0003] The purpose of the present invention is to overcom...
