Abstract

The invention relates to the technical field of air conditioning, in particular to a multi-split air conditioner and a self-cleaning control method thereof. Specifically, the multi-split air conditioner comprises an outdoor unit and an indoor unit set, and the indoor unit set comprises a first indoor unit and at least one second indoor unit. The self-cleaning control method of the multi-split airconditioner comprises the steps that under the condition that all indoor units of the air conditioner are in the refrigeration condition, the first indoor unit executes the self-cleaning mode; and anelectronic expansion valve corresponding to the second indoor unit is closed. According to the control method, the electronic expansion valve of the second indoor unit is closed, it is ensured that sufficient refrigerants circulate in a pipeline system of the first indoor unit, therefore, frosting of the first indoor unit is more completely filled, stripping and flushing effect on the dust and dirt is better, and the self-cleaning effect is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a one-driver-multiple air conditioner and a self-cleaning control method thereof. Background technique [0002] During the working process of the air conditioner, the air exchanges heat with the heat exchanger of the indoor unit. Since the air contains dust, the dust in the air will also adhere to the heat exchanger. With the long-term use of the air conditioner, dust will be deposited on the indoor unit. Severe dust accumulation on the heat exchanger will affect the heat exchange effect of the heat exchanger, and will also breed a large number of bacteria, especially when the indoor air flows through the indoor unit, the air will carry dust and bacteria and blow to the indoor space, thereby causing users Health is a threat. In view of this, the air conditioner needs to be cleaned in time, and the air conditioner in the prior art often cleans the indoor unit by running...
