PROBLEM TO BE SOLVED: To provide a heat pump type air conditioner capable of attaining both energy saving and comfort performance when a low load air conditioning is applied.SOLUTION: There are provided at least one air-supply side heat exchanger 3, a plurality of compressors 2a and 2b for compressing and transferring refrigerant and heat source side heat exchangers 4a and 4b, and there are provided a plurality of heat pumps 5a and 5b cooperatively using the air-supply side heat exchanger 3, a vaporization type humidifier 6 and a steam type humidifier 7. Refrigerants in every other or every two other different heat pumps 5a and 5b flow with respect to adjoining many heat transfer pipes 12a and 12b in a direction along an air inlet face 13 of the air-supply side heat exchanger 3. There is provided a control apparatus 8 for changing over a starting and a stopping of the compressors 2a and 2b of the plurality of heat pumps 5a and 5b according to an increased or decreased load of air conditioning and adjusting increasing or decreasing of output.SELECTED DRAWING: Figure 1 |
