Air conditioner control system and control method

Abstract

The invention provides an air conditioner control system and a control method, the air conditioner control system comprises a compressor (1), an indoor heat exchanger (2) and an outdoor heat exchanger(3), wherein a branch (4) is further formed on a pipeline between a high pressure exhaust end (11) of the compressor (1) and the indoor heat exchanger (2), a base plate heating module (5) is arrangedon the branch (4) and can heat an air conditioner base plate, and the other end of the branch (4) is connected back to a low pressure suction end (12) of the compressor. According to the air conditioner control system and the control method, a refrigerant can be used for deicing, the energy can be fully used, the energy efficiency is improved, power dissipation is reduced, energy conservation andemission reduction are realized, and the reliability problem is solved; the problem that ice is difficult to melt on the base plate under the extreme cold condition so that the fan blade and the iceblock are in friction can be solved, and the problems that the operation noise of the outer machine is larger and mechanical faults are easy to occur in the severe cold area are solved from the source.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to an air conditioner control system and control method. Background technique [0002] At present, as the requirements for environmental protection are getting higher and higher, the heating method in low-temperature environments is gradually transitioning from coal heating to air-conditioning heating. However, when the temperature is minus 15 degrees, the existing silicone electric heating belt method is limited by the silicone material, and the electric heating power is low, which cannot meet the needs of the chassis to melt ice. If the ice melting method of the heating pipe is used, the electric heating power can be increased to 300W, which can meet the needs of chassis ice melting at minus 15 degrees. security risks. If the system's refrigerant is used to heat the chassis to solve the problem of unsmooth drainage caused by the freezing of the chassis, it can no...
