Problems solved by technology
[0005] (2) For units operating under T3 high temperature conditions, the cooling effect of the existing technology on the compressor drive plate is not significant
Especially, when the outdoor unit is running at low frequency and the indoor unit is turned on alone, the flow of refrigerant is insufficient to cool down the compressor drive board, which will cause the unit to report to the compressor IPM protection and stop the unit
[0006] (3) When the unit is operated under high temperature conditions for a long time, the aging of the components of the compressor drive board of the unit will be accelerated, and the solder joints will fall off
[0007] (4) When the unit operates at low temperature for a long time, condensation will appear in the electrical box

The invention discloses an air conditioner and a control method for the air conditioner. The air conditioner includes a compressor drive board, a refrigerant cooling module, a first solenoid valve, a second solenoid valve and a controller; the liquid inlet on one side of the refrigerant cooling module is connected to the connecting pipeline through the first solenoid valve, and the refrigerant cooling module The liquid outlet on one side is connected to the same section of connecting pipeline through the second solenoid valve; the controller controls the opening degrees of the first solenoid valve and the second solenoid valve according to the temperature of the compressor drive plate to reduce the temperature of the compressor drive plate. controlled within the predetermined range. Through the above technical solution, the present invention can control the opening of the first electromagnetic valve and the second electromagnetic valve according to the temperature of the compressor driving plate, thereby controlling the amount of refrigerant entering the refrigerant cooling module, so as to control the compressor driving plate The purpose of cooling temperature.
Description
technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner and a control method for the air conditioner. Background technique [0002] At present, multi-split units usually use refrigerant to cool the compressor driver board, which is mainly cooled by liquid pipes. The working principle of this method is that after the refrigerant exchanges heat in the condenser of the outdoor unit, it goes around to the refrigerant cooling module to cool the compressor drive plate, and then the refrigerant flows out to the liquid pipe. [0003] Although the above-mentioned technical scheme in the prior art can basically meet the requirements, there will be the following problems: [0004] (1) Large pressure loss. The pipe section of the refrigerant from the outlet pipe of the condenser to the refrigerant cooling module is gradually reduced due to the diameter of the pipe, so that the pressure loss of the unit also increases. [0005...
