AIR CONDITIONER UNIT CONTROL METHOD AND DEVICE, AND AIR CONDITIONER UNIT
Document Type and Number:
WIPO Patent Application WO/2019/153888
Kind Code:
A1
Abstract:
Disclosed are an air conditioner unit control method and device. The method comprises: acquiring a return air temperature, a condensation temperature, an evaporation temperature, compressor parameters and draught fan parameters of an air conditioner unit; determining a pre-set evaporation temperature according to the return air temperature, the condensation temperature, the evaporation temperature, the compressor parameters, the draught fan parameters, a compressor power curve and a draught fan power curve, wherein at the pre-set evaporation temperature, the sum of the compressor power and the draught fan power is the minimum; determining, according to the compressor power curve and the draught fan power curve, a pre-set compressor frequency and a pre-set draught fan frequency corresponding to the pre-set evaporation temperature; controlling a compressor according to the pre-set compressor frequency; and controlling a draught fan according to the pre-set draught fan frequency. In the method, the pre-set compressor frequency and the pre-set draught fan frequency are respectively determined by acquiring various operation parameters, establishing the compressor power curve and the draught fan power curve and comprehensively utilizing the compressor power curve and the draught fan power curve, such that the compressor and the draught fan can be simultaneously controlled in a precise manner, thereby solving the technical problems in relevant methods of a low control precision of an air conditioner unit and a poor control effects.
