示器に送る自動車用冷房機の冷媒量検出装置。 An automobile air conditioner that uses a vapor compression refrigeration cycle in which refrigerant compressed by a compressor is condensed and liquefied in a condenser, then this liquid refrigerant is expanded and evaporated in an evaporator, and the vaporized refrigerant is sent back to the compressor. A supercooling degree measurement sensor is provided between the condenser and the evaporator to measure the degree of supercooling of the refrigerant based on the temperature and pressure of the refrigerant in this area, and a signal from this degree of supercooling measurement sensor is input. The controller sends a signal to a display indicating that the amount of refrigerant is too large if the degree of supercooling in the portion is greater than a predetermined value based on a signal after a certain period of time has elapsed after the compressor is started. On the contrary, if the degree of subcooling is above a predetermined value, a refrigerant amount detection device for an automobile air conditioner sends a signal to a display indicating that the refrigerant amount is insufficient.
