Abstract

A refrigerant charging device and a refrigerant charging system include a refrigerant charging flour path having a refrigerant charging port connected to a refrigerant flow path of an air conditioner, a valve provided at the refrigerant charging flow path, and a control device configured to control the valve. The control device includes a discharging superheat calculator configured to calculate the discharging superheat degree from a refrigerant temperature and a refrigerant pressure at a discharge side of a compressor, and a valve controller configured to control the opening and closing state of the valve based on the calculated discharging superheat degree calculated by the discharge super-heat calculator.
