    Abstract: An air-conditioning apparatus (1) capable of reliably recovering lubricant accumulated in indoor units (3A,3B,3C) and their refrigerant circuit, regardless of the refrigerant-pipe length differences of the indoor units connected to each other, has been desired, and includes an operating unit (22) configured to carry out liquid return at each indoor unit, to carry out an oil-recovery operation for recovering lubricant accumulated in the refrigerant circuit, and to complete the oil-recovery operation when liquid return is detected at the outdoor unit (2). The operating unit includes a detecting unit configured to detect the refrigerant pipe length of each of the indoor units, a storing unit configured to store the refrigerant pipe lengths detected by the detecting unit, and a control unit configured to change the operation time during the oil-recovery operation on the basis of the refrigerant pipe length of each of the indoor units stored in the storing unit.

    Abstract: PROBLEM TO BE SOLVED: To provide a supercritcal-cycle heat pump with which the capacity to return oil from a system side where an injection circuit is provided can be enhanced by employing POE oil as lubricant, and concerns with regard to an increase in the dilution ratio and a decrease in the oil viscosity when the POE oil is employed can be eliminated.SOLUTION: The supercritical-cycle heat pump 1 includes an injection circuit 11 for injecting intermediate-pressure refrigerant gas being separated by a gas-liquid separator 6 into a sealed housing 14, having intermediate pressure in the interior thereof, in a multistage compressor 2, and employs CO 2 refrigerant as a working medium. The supercritical-cycle heat pump 1 employs POE oil 17 as lubricant for the multidstage compressor 2, and includes a controller 25 which determines the viscosity of the POE oil 17 on the basis of the solubility of the POE oil 17 in the CO 2 refrigerant and temperature thereof, the solubility of the POE oil in the CO 2 refrigerant being determined by pressure and temperature of intermediate-pressure refrigerant and which controls the pressure of the intermediate-pressure refrigerant through a first electronic expansion valve 5 so that the pressure thereof is controlled within a preset usage limit range in order to keep the viscosity of the POE oil 17 above the certain viscosity zone.
