<p>An air-conditioner is provided to prevent the temperature of coolant inhaled into the compressor from rising due to the recovered oil by lowering the temperature the coolant or oil stored in the accumulator with the high temperature oil separated by the oil separator. An air-conditioner(1) comprises a compressor(11), an oil separator(12) separating the coolant and oil discharged from the compressor, an oil recovery pipe(16) in which the oil separated from the oil separator flows, and a heat exchanger which induces heat-exchange between the internal fluid and the separated oil. The heat exchanger is connected to the compressor so that the heat-exchanged oil is inhaled into the compressor.</p> |
