摘要： A refrigeration cycle apparatus includes a refrigerant circuit connecting a compressor, a heat source-side heat exchanger, an expansion device, and a use-side heat exchanger to each other by connecting pipes, an outside air temperature sensor configured to detect an outside air temperature, and a controller configured to operate the refrigeration cycle apparatus and to switch between a normal operation mode for controlling the refrigerant circuit based on an operation load of the use-side heat exchanger and a refrigerant amount determining mode for determining whether or not an amount of refrigerant in the refrigerant circuit is appropriate. The controller is configured to switch the normal operation mode to the refrigerant amount determining mode when the outside air temperature detected by the outside air temperature sensor is within a set temperature range.

摘要： An air-conditioning apparatus is able to ensure an appropriate flow rate of refrigerant and an appropriate amount of oil returned to a compressor that match operation conditions regardless of an operating state of a refrigerant circuit and a change in an operation condition. The air-conditioning apparatus includes: a first detector configured to detect a refrigerant temperature within an accumulator; a storage unit configured to store information regarding a two-layer separation temperature of refrigerant and refrigerating machine oil; a determiner configured to compare the refrigerant temperature with the two-layer separation temperature and determine a two-layer separation state of the refrigerant and the refrigerating machine oil; a second detector configured to detect a state of the refrigerant sucked by the compressor; and a control unit configured to adjust an opening degree of a flow control valve on the basis of the two-layer separation state and a state of the sucked refrigerant.

摘要： An air conditioner includes: an indoor unit; an outdoor unit; and a control unit that controls operation of the indoor unit and the outdoor unit. The outdoor unit includes: an outdoor unit fan that takes in air; an outside air temperature detection unit that detects an outside air temperature that is a temperature of outside air; and an air pressure acquisition unit that acquires an air pressure of outside air. The control unit calculates an air property value of air at an installation location of the air conditioner based on an outside air temperature acquired by the outside air temperature detection unit and an air pressure acquired by the air pressure acquisition unit, and controls the outdoor unit fan based on the air property value.
