<p><P>PROBLEM TO BE SOLVED: To solve the problem wherein since a branch pipe is provided in the direction in which the main current of a refrigerant discharged from a compressor flows to a condenser, a passage resistance to a refrigerant control device of a solenoid valve is selected only to be low, and a large amount of defrosting time is required. <P>SOLUTION: An outdoor blower 8 is operated for performing heat exchange between outside air and an evaporator 4. A pipeline between the compressor 1 and a four-way valve 11 includes the branch pipe 51 in which a discharge gas refrigerant of the compressor 1 has the main current in the bypass pipe direction, whereby the dynamic pressure component of the discharge gas refrigerant is applied to a first discharge gas bypass 31 side, so that the fractionating ratio at the branch pipe 51 part is remarkably larger at the discharge gas bypass 31 side, and the degree of influence of passage resistance of the refrigerant control device 40 installed in the discharge gas bypass 31 is not only decreased, but also the defrosting time can be reduced, and as an air conditioner, comfort during heating operation can be improved. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
