Abstract
PURPOSE: To reduce a defrosting operation time by arranging a bypass refrigerant circuit between the outlet side of an indoor side heat exchanger and the inlet side of an outdoor side heat exchanger, accumulating heat with first and second solenoid valves opened and closed and defrosting with the first and second solenoid valves closed and opened, respectively.
CONSTITUTION: When first and second solenoid valves 23 and 25 are set to be opened and closed, respectively, in a bypass refrigerant circuit 26, a refrigerant which has passed an indoor side heat exchanger 3 is accumulated in a heat accumulator 24 via the first solenoid valve 23 and a suction tube 27 in the same condition as that of the refrigerant outputted from the indoor side heat exchanger 3. That is, the refrigerant is accumulated at a point A in the condition of a liquid phase refrigerant. The liquid refrigerant at the point A moves on an isotherm represented by a dashed line to be changed to a condition represented in a point B. At this time, a refrigerant gas 1a discharged in a refrigerant circuit and a circuit condition as represented by a full line in a room heating operation is changed to that as represented by a dotted line in a defrosting, operation, a refrigerant gas pressure in a low pressure refrigerant circuit portion being raised. As a result, a low pressure at a temperature below 0°C is increased to the pressure at a temperature above 0°C and frost attached to an outdoor heat exchanger 5 is molten to be removed.
