Abstract
The invention relates to an automobile refrigeration air conditioner approximate to an isothermal compression working condition. A system is formed by combination of a vapor compression refrigeration cycle and a secondary refrigerant liquid flow cycle responsible for discharging heat of a compressor body. The system enables a refrigeration compressor body to be soaked in a liquid-state secondary refrigerant to discharge heat, and heat temperature accumulated heat on the compressor body is eliminated in time. A malignant refrigeration cycle of the hotter the compressor body, the larger mechanical load and the higher mechanical load, the hotter the compressor body due to the fact that an existing adiabatic compression working condition is unsmooth in heat removal is changed into a benign refrigeration cycle with good refrigeration efficiency. Therefore, the automobile refrigeration air conditioner approximate to the isothermal compression working condition reduces oil consumption substantially and guarantees that various automobile air conditioners can be used in an all-weather, all time interval and low-cost mode.
