Embodiment approach

[0076] As an implementation manner, the above-mentioned indoor unit includes at least one priority indoor unit, which may also be called a VIP indoor unit, and the above-mentioned method may also include the following steps:

[0077] If the indoor unit corresponding to the single indoor unit cleaning instruction is the priority indoor unit, and at least one other indoor unit is in the heating mode, control the indoor unit in the heating mode to switch to the standby mode, and determine that the air conditioning system meets the operating mode conditions. If the indoor unit corresponding to the single indoor unit cleaning command is not the priority indoor unit, and at least one other indoor unit is in the heating mode, it is determined that the air conditioning system does not meet the operation mode condition. In order to give priority to the needs of VIP indoor units, when the priority indoor unit is cleaning, even if other indoor units are heating, the other indoor units nee...

Abstract

The present invention provides an air-conditioning system control method, device, and air-conditioning system. The method includes: if the air-conditioning system satisfies a preset operating mode condition, obtaining return air parameters of the compressor and / or the temperature difference between the inlet and outlet of the heat exchanger; Perform cooling mode based on return air parameters and / or temperature difference to clean the heat exchanger. In the embodiment of the present invention, the evaporation temperature of the heat exchanger can be judged by the return air parameters of the compressor, the flow rate of the refrigerant can be judged by the temperature difference between the inlet and outlet of the heat exchanger, and the operating parameters of the air conditioning system can be dynamically adjusted according to the return air parameters and / or temperature difference. It can ensure that enough condensed water condenses on the surface of the heat exchanger to wash away impurities, and realize automatic and efficient cleaning of the heat exchanger, thereby reducing energy consumption and improving air quality.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a control method and device for an air conditioning system and the air conditioning system. Background technique [0002] The heat exchanger of the air conditioner is an important equipment for cold and heat exchange. In order to improve the heat exchange efficiency, finned heat exchangers are often used. Fins are added to ordinary base pipes to enhance heat transfer. The fin structure of the existing finned heat exchanger is complex, most of which are window type, bridge type or corrugated type. Deposits easily on fin surfaces. [0003] If the impurities on the surface of the heat exchanger cannot be removed in time, it will not only affect the heat exchange efficiency of the heat exchanger and increase the energy consumption of the air conditioner, but also the accumulation of dust will easily breed bacteria, affect the air quality, and even cause diseases. ...
