Abstract
PURPOSE: To effect defrost operation without requiring reverse operation at the time of heating operation by providing means for switching a slide valve between cooling and heating positions, and a defrost valve for defrost duct and opening the defrost valve through the switching means at the time of heating operation. CONSTITUTION: A valve 1 is provided with a coupling port 1a to the delivery side of a compressor, a coupling port 1b to the suction side arranged on one circumferential direction, and coupling ports 1c, 1d to two heat exchangers arranged on the opposite sides of a coupling port 1b. The three juxtaposed coupling ports 1b, 1c and 1d are switched by a slide valve 7. A stepping motor 9 switches the slide valve 7 between cooling and heating positions and the valve 1 is further provided with a defrost valve 12 for opening/closing the coupling port 1e of a defrost duct 10..The defrost valve 12 is opened through the stepping motor 9 at the time of heating operation. According to the arrangement, defrost operation can be effected by opening the defrost valve 12 without requiring reverse operation at the time of heating operation of heat pump and the efficiency of heating operation can be enhanced.
