摘要： The present invention relates to a method for controlling the operation of a compressor for preventing noise that occurs in case of the shortage of refrigerant flow caused by less discharge capacity of the compressor of an air conditioner for a vehicle. The compressor includes a cylinder bore for compressing a refrigerant, a piston inserted into the cylinder bore, a swash plate having a controllable slope with respect to a drive shaft, and a control valve for controlling the slope of the swash plate. The discharge capacity of the compressor is increased if it is determined that vehicle speed and accelerating rate satisfy predetermined conditions. If a low flow rate state of refrigerant of the compressor is predicted, the ECV duty is increased to prevent the compressor from entering the low flow rate state, thereby improving the workability of the compressor and solving the noise problem.

摘要： The present invention relates to a method for controlling the operation of a compressor for preventing noise that occurs in case of the shortage of refrigerant flow caused by less discharge capacity of the compressor of an air conditioner for a vehicle. In a method for controlling a compressor of an air conditioner for a vehicle according to the present invention, wherein the compressor includes a cylinder bore 13 for compressing a refrigerant, a piston 15 inserted into the cylinder bore 13, a swash plate 48 having a controllable slope with respect to a drive shaft 40, and a control valve 35 for controlling the slope of the swash plate 48, the discharge capacity of the compressor is increased if it is determined that vehicle speed and accelerating rate satisfy predetermined conditions. According to the present invention, a low flow rate state of refrigerant of the compressor is predicted, and then ECV duty is increased to prevent the compressor from entering the low flow rate state of refrigerant, thereby improving the workability of the compressor and solving noise problem.
