摘要： Provided is an air conditioner capable of reducing the error in judgment of the refrigerant quantity even when the temperature in each target space to be air conditioned by the air conditioner is different. An air conditioner (1) that adjusts the temperature in a target space includes a refrigerant circuit (10) and a controller (8). The refrigerant circuit (10) is configured by the interconnection of a compressor (21), an outdoor heat exchanger (23), indoor expansion valves (41, 51), and indoor heat exchangers (42, 52). The controller (8) adjusts the temperature such that predetermined temperature is reached in a target space. In addition, the controller (8) judges the refrigerant quantity in the refrigerant circuit (10) based on at least one value of operation state quantity of constituent equipment or refrigerant flowing in the refrigerant circuit (10). The controller (8) achieves a state in which the target space temperature satisfies a predetermined temperature condition.

摘要： When during a first action of a refrigeration system the internal cold storage temperature is held at a desired temperature by an evaporator, the refrigeration system performs a second action of increasing the cooling capacity of the evaporator to decrease the internal cold storage temperature. When during the second action the internal cold storage temperature reaches a minimum temperature Tmin, the refrigeration system stops a compressor and performs a third action. When during the third action the internal cold storage temperature reaches a maximum temperature Tmin, the refrigeration system drives the compressor and performs the first action.

摘要： A control algorithm is developed which takes corrective action in the event that system conditions indicate there may be an inadequate flow of lubricant in the system. In particular, if a discharge pressure is below a predetermined amount or if the suction modulation valve is throttled, there is a possibility of inadequate lubricant flow. The system control then turns off the condenser fan, and if that first step is not sufficient, may also turn on an evaporator heater and then control a suction modulation valve. A fail safe control loop also takes effect if the condition sensor appears to have failed.

摘要： A refrigerant vapor compression system includes a flash tank disposed in the refrigerant circuit intermediate a refrigerant heat rejection heat exchanger and a refrigerant heat absorption heat exchanger. The flash tank has a shell defining an interior volume having an upper chamber, a lower chamber and a middle chamber. A first fluid passage establishes fluid communication between the middle chamber and the upper chamber and a second fluid passage establishing fluid communication between the middle chamber and the lower chamber. An inlet port opens to the middle chamber. A first outlet port opens to the upper chamber and a second outlet port opens to the lower chamber.
