摘要： PROBLEM TO BE SOLVED: To sufficiently recover not only a dead coolant at a radiator side but also a dead coolant of an evaporator on the rear seat in a dual air conditioning type air conditioner for vehicle exhibiting a hot gas heater function.
SOLUTION: A refrigeration cycle is set in the cooling mode state to carry out coolant recovery operation at activation of heating mode by a hot gas heater cycle (S30). Thereafter, the refrigeration cycle is switched to the heating mode state (S50). At the heating mode, the front seat side air conditioning unit is set in an external air mode and external air is blown to a front seat side evaporator by a front seat side fan. When it is determined that an internal air temperature is higher than the temperature of the coolant of the rear seat side evaporator at the heating mode, a rear seat side fan is operated to blow the internal air to the rear seat side evaporator.

摘要： PROBLEM TO BE SOLVED: To determine a filling amount through sight glass even if a refrigerant has a low two-layer separation temperature.
SOLUTION: The refrigerating cycle device 1 is equipped with an oil separator 8 in a high pressure gas passage. The oil separator 8 controls an oil content ratio in a high pressure liquid refrigerant to 3% or smaller. An internal heat exchanger 7 is provided between a condenser 3 and the sight glass 6. The internal heat exchanger 7 can lower the temperature of the high pressure liquid refrigerant by about 10°C. In the refrigerant and the oil, a combination is selected indicating a two-layer separation temperature Ts within a first range TR1 of 45-55°C when the oil content ratio OCR is 3%, and indicating a two-layer separation temperature Ts within a second range TR2 of 35-45°C when the oil content ratio OCR is 6%. As a result, even in a combination of the refrigerant and oil indicating a comparatively low two-layer separation temperature Ts, the observation of a cloudy state caused by two-layer separation through the sight glass 6 can be avoided.
