Abstract

The invention provides an air conditioner and a control method and control system thereof. The air conditioner comprises a plurality of indoor units and a plurality of throttling devices correspondingto the indoor units one to one. The control method includes the steps of judging whether temperature-reaching overheating-prevention entering conditions are met or not when the indoor units for reaching the set temperature through heating exist among the indoor units, and if yes, controlling the throttling devices corresponding to at least part of the indoor units among the indoor units for reaching the set temperature to be periodically started and stopped. By means of the control method, the too high temperature or even protection of an indoor evaporator can be effectively avoided, meanwhile the excessive rising of the indoor environment temperature can be avoided, and the reliability and comfort of the air conditioner are improved on the premise of ensuring the oil return and liquid return of a compressor.

Description

technical field [0001] The present invention relates to the technical field of household appliances, in particular to an air conditioner control method, an air conditioner control system and an air conditioner with the control system. Background technique [0002] At present, one-to-many air conditioners are more common in the market and belong to a large branch of split air conditioners. Due to the large size of the one-drag multi-air conditioning system, when some indoor units reach the set temperature during heating, in order to ensure the operation of oil return and liquid return, the electronic expansion valve corresponding to the temperature-reaching indoor unit is required to maintain a certain opening degree. It will cause the indoor ambient temperature to continue to rise after reaching the set temperature, resulting in a decrease in customer comfort. [0003] In the related art, the problem of overheating after heating is solved by reducing or stopping the wind sp...
