Abstract:
An air-conditioning apparatus and an operation controller of the air-conditioning apparatus are capable of maintaining oil in a compressor at an appropriate amount and preventing efficiency degradation due to oil compression in the compressor. The air-conditioning apparatus includes a refrigerant circuit in which a condenser, an expander, an evaporator, the compressor, and an oil separator are connected by pipes, and an oil return circuit configured to return oil from the oil separator to the compressor, in which the compressor includes an oil concentration sensor configured to detect oil concentration inside the compressor, and the oil return circuit includes multiple solenoid valves that are each opened or closed corresponding to the oil concentration detected by the oil concentration sensor.

Claim (Index 5):
An operation controller of an air-conditioning apparatus, comprising:\n a detection unit configured to detect oil concentration inside a compressor by an oil concentration sensor; a memory unit configured to store a threshold concentration for opening or closing a plurality of solenoid valves, the threshold concentration being set in each of the plurality of solenoid valves; and a control unit configured to compare the oil concentration detected in the detection unit with each of the plurality of the threshold concentrations, and, when the oil concentration is higher than one of the plurality of the threshold concentrations, close the solenoid valve in which the one of the plurality of the threshold concentrations is set.
