Abstract

The invention discloses a refrigeration control method of a multi-split air conditioner. The method includes the steps that in the operation process of the air conditioner, capability demand values of indoor units, in a running state, of the air conditioner are acquired; set temperatures of the indoor units and the current indoor environment temperature are acquired; the accumulated value of the capability demand values of the indoor units is corrected according to the set temperatures of the indoor units and the current indoor environment temperature, and a corrected value is obtained; the operation frequency of a compressor is correspondingly adjusted according to the corrected value. The invention further discloses the multi-split air conditioner. The refrigeration demand of an indoor room is met, and meanwhile the frequency of the compressor is accurately controlled; besides, the air conditioner is good in energy efficiency.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a one-driver-multiple air conditioner and a refrigeration control method thereof. Background technique [0002] At present, various technical difficulties have been encountered in the gradual promotion of frequency conversion one-drag multi-air conditioners. During the operation of the one-to-multiple air conditioner, the set temperature of the indoor unit and the indoor ambient temperature are obtained, and the frequency of the compressor is controlled according to the temperature difference between the set temperature of the indoor unit and the indoor ambient temperature. However, this control scheme cannot meet the cooling requirements of each indoor room, and the frequency control of the compressor does not take into account the cooling capacity of the indoor unit, so the frequency control of the compressor is not accurate enough. Contents of the invention [0003] The main...
