Abstract
PURPOSE:To enable execution of comfortable heating operation and to improve heating efficiency, by providing a temperature difference detecting device, capable of detecting a difference between high and low temperatures in a room to be air-conditioned during heating operation, and a control device to repeatedly change a pressure reducing amount of a pressure reducing device for heating in a given range at intervals of a given time. CONSTITUTION:High temperature and high pressure gas discharged from a compressor 1 during heating operation is fed from a 4-way valve 2 to an indoor unit 8 through a connection piping 12b and is radiated and condensed by means of a heat exchanger 9 on the indoor side to perform heating. The gas is fed to an indoor unit 7 through a check valve 11 and a connection piping 12a and is reduced in a pressure by a pressure reducing device 4 for heating. The gas is radiated and vaporized by a heat exchanger 3 on the outdoor side, and is circulated to the compressor 1 through the 4-way valve 2 and an accumulator 6. In high and low temperature in a room 13 to be air-conditioned detected by means of a temperature difference detecting device 14 is increased to a value higher than a given value, repeat operation, is performed in which the opening of the pressure reducing device 4 for timewise heating is reduced for a given time by means of a control device 15 to a given range,after that, the opening in increased for a given time to a given range.
