The invention relates to the technical field of air conditioners, and in particular provides a control method for preventing condensation of an indoor unit in an air conditioner. The present invention aims to solve the problem in the prior art that it is difficult for an air conditioner to achieve the purpose of preventing condensation and ensuring the effect of cooling or dehumidification in a short period of time. For this purpose, the present invention can maintain the current opening degree of the electronic expansion valve of the first indoor unit and only adjust the opening of the electronic expansion valve of the second indoor unit when the running first indoor unit has the risk of condensation. until the condensation risk of the first indoor unit is eliminated; then, when the condensation risk of the first indoor unit is eliminated, close the electronic expansion valve of the second indoor unit; at the same time, open the electronic expansion valve of the first indoor unit at its current opening. Increase the compensation opening on the basis of the degree. Through this method, the purpose of preventing the condensation phenomenon of the first indoor unit in time and ensuring the cooling or dehumidifying effect of the first indoor unit can be achieved.
Description
technical field [0001] The invention relates to the technical field of air conditioners, and in particular provides a control method and a storage medium for preventing condensation of an indoor unit in an air conditioner. Background technique [0002] One-to-many air conditioner is a large branch of split air conditioner. It has multiple indoor units that can be used in multiple rooms, and multiple indoor units share one outdoor unit. When the indoor unit is running in cooling mode or dehumidifying mode, the indoor heat exchanger in the indoor unit has the function of an evaporator, the indoor fan drives the indoor air into the indoor unit, the indoor heat exchanger absorbs the heat of the indoor air, and then blows the cold air. to the interior. The cold air blown by the indoor unit and the indoor hot air meet at the air outlet of the indoor unit. If the air temperature of the indoor unit is lower than the dew point temperature of the indoor environment at this time, the ...
