Abstract

The invention discloses a multi-split air conditioner control method and system. The actual environment temperature, the set temperature, the actual environment humidity and the set humidity of each started indoor unit are acquired; and the comfortable sensation load rate of each started indoor unit is calculated, the total comfortable sensation load is calculated, and the frequency of a compressor and the opening degrees of expansion values of the indoor units are adjusted according to the total comfortable sensation load. According to the multi-split air conditioner control method, the temperature, the humidity and the indoor unit capacity hosepower are taken into consideration, the total comfortable sensation load is worked out, the frequency of the compressor and the opening degrees of the expansion values of the indoor units are adjusted according to the total comfortable sensation load, frequent frequency fluctuation of the compressor is avoided, the comfortable sensation judgment accuracy is also improved, the comfortable sensation of the indoor units is improved, the ideal indoor unit comfortable sensation is achieved, the balance and the stability of a multi-split air conditioner are improved, the user satisfaction degree is improved, and the market competitiveness of the multi-split air conditioner is improved.

Description

technical field

[0001] The invention belongs to the technical field of air conditioning, and in particular relates to a multi-connection control method and system. Background technique

[0002] In a multi-split system, usually one outdoor unit is connected to multiple indoor units. Each indoor unit has an expansion valve. By controlling the opening of the expansion valve, the flow of refrigerant entering the heat exchanger of the indoor unit is adjusted to realize the exchange of cold and heat with the outside world.

[0003] The environment in which the indoor unit is located is different, and the requirements for air quality vary greatly. Judging the comfort of each indoor unit and achieving system stability in the shortest possible time to achieve an ideal air-conditioning environment for indoor units is the key to multi-connected control.

[0004] At present, the comfort judgment of the indoor unit only considers the temperature factor, and the comfort judgment is not ...
