Dual Compressor Inverter System for Refrigerator Vehicles

냉장 차량용 듀얼 컴프레서 인버터 시스템

In the single type mechanical compressor mounted on the refrigerated vehicle, one compressor is responsible for the refrigerator function of the air conditioner and the refrigerator, so it is difficult to maintain a certain refrigeration temperature in the summer. Particularly, in a mechanical compressor using an engine as a power source, the refrigeration quality is deteriorated due to unstable rotation of the engine. In this paper, we propose a three - phase inverter of a dual compressor system that uses an electric compressor separately from a mechanical compressor of a refrigerated vehicle. The output characteristics of the developed inverter were verified through a vehicle air conditioning simulator.
