    摘要: A refrigerating air-conditioning apparatus, at least provided with no possibility that a foreign material returns to a compressor from an accumulator at a time of the pipeline-cleaning operation firstly, and provided with a possibility to perform a collecting operation for the foreign material in a short time secondary, is provided.The heat-source side unit includes an accumulator provided with a function to separate and collect the foreign material in an existing pipeline, a collecting container for collecting the foreign material separated by the accumulator, and an oil return pipeline for returning refrigerating machine oil to the compressor via a flow amount adjusting device, installed at a lower portion of the accumulator, and at a time of ordinary cooling or heating operation, the refrigerating machine oil is caused to flow into the oil return pipeline, and at a time of pipeline cleaning and foreign material-collecting operations, the flow amount adjusting device is fully closed.

    摘要: An air conditioner is arranged so as to be able to accurately judge a refrigerant filling state within the air conditioner regardless of environmental and installation conditions. The air conditioner has a computing section 102 for computing a condenser liquid phase area ratio that is a value related to an amount of liquid phase portion of the refrigerant within a high pressure-side heat exchanger, based on refrigerant condensation temperature of the high pressure-side heat exchanger, outlet super-cooling degree of the high pressure-side heat exchanger, intake air temperature of the high pressure-side heat exchanger, a difference of enthalpy of inlet and outlet of the high pressure-side heat exchanger and specific heat at constant pressure of a refrigerant solution at the outlet of the high pressure-side heat exchanger and a judging section 106 for judging the refrigerant filling state within the air conditioner based on a comparison of the value computed by the computing section 102 with a predetermined value.
