The invention relates to the technical field of air conditioners, and particularly provides a control method for preventing condensation of indoor units in an air conditioner. The control method aims to solve the problem that in the prior art, an air conditioner cannot easily achieve the purposes of preventing the condensation phenomenon from happening and being capable of guaranteeing the refrigeration or dehumidification effect within a short time period. In order to achieve the purpose, the control method comprises the steps that when the first indoor unit which is in operation has a condensation risk, the current opening degree of an electronic expansion valve of the first indoor unit is kept, and only the opening degree of an electronic expansion valve of the second indoor unit is adjusted until the condensation risk of the first indoor unit is eliminated; then when the condensation risk of the first indoor unit is eliminated, the electronic expansion valve of the second indoor unit is closed; and meanwhile, the compensation opening degree is increased for the electronic expansion valve of the first indoor unit on the basis of the current opening degree of the electronic expansion valve of the first indoor unit. By means of the method, the purposes that the first indoor unit can be prevented against the condensation phenomenon in time, and the refrigeration or dehumidification effect of the first indoor unit is guaranteed can be achieved.
Description
technical field [0001] The invention relates to the technical field of air conditioners, and specifically 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 conditioners are a large branch of split air conditioners. 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 dehumidification mode, the indoor heat exchanger in the indoor unit functions as an evaporator, the indoor fan drives the indoor air into the indoor unit, the indoor heat exchanger absorbs the heat of the indoor wind, and then blows the cold air to the interior. The cold air blown by the indoor unit and the hot indoor air meet at the air outlet of the indoor unit. If the temperature of the air outlet from the indoor unit is lower than the dew point temperature of the indoor environment at t...
