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 invention provides a control method and device for an air conditioning system as well as the air conditioning system. The method comprises the following steps: obtaining gas return parameters of acompressor and / or temperature difference of an inlet and outlet of a heat exchanger if the air conditioning system meets a preset operation mode condition; and performing a refrigerating mode according to the gas return parameters and / or the temperature difference to clean the heat exchanger. According to the embodiment of the invention, the gas return parameters of the compressor can be used forjudging an evaporation temperature of the heat exchanger, and the refrigerant flow size can be judged according to the temperature difference of the inlet and outlet of the heat exchanger; operationparameters of the air conditioning system can be dynamically regulated according to the gas return parameters and / or the temperature difference, so that much condensate water can be guaranteed to be condensed on the surface of the heat exchanger for scouring impurities, and automatic and efficient cleaning of the heat exchanger is realized, and therefore, energy consumption is reduced, and air quality is improved.

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. ...
