摘要： An air conditioning system including a refrigerant circulation route, a compressor, a condenser, an expansion valve, an evaporator and a pressure sensor for detecting pressure in the circulation route comprises a refrigerant phase detector provided on the circulation route between the condenser and the evaporator where the refrigerant should be in a liquid phase for detecting whether the refrigerant is in a liquid phase or in a vapor phase and a control for determining whether the compressor is in a locked state in accordance with the signals from the refrigerant phase detector and the pressure sensor. The air conditioning system can precisely determine and detect both compressor lock up and refrigerant leakage without providing a rotation detecting sensor for the compressor.

摘要： A refrigeration cycle apparatus includes a compressor, a condenser, a pressure-reducing mechanism, an evaporator, an orifice provided in a refrigerant flow path from the compressor to the pressure-reducing mechanism, a differential pressure sensor that detects the differential pressure before and after the orifice, a refrigerant flowrate calculating portion that calculates a refrigerant flowrate based on the differential pressure, and a torque estimating portion that estimates the torque required to drive the compressor based on the refrigerant flowrate calculated by the refrigerant flowrate calculating portion, the intake pressure of the compressor, and the discharge pressure of the compressor.
