Refrigerating cycle apparatus

摘要

A refrigerating cycle apparatus is disclosed in which a refrigerating cycle is connected circularly through a compressor (1), a condenser (3), a flow controller (6), and an evaporator (5, 7), respectively. The flow controller (6) comprising a multi-directional valve (12) connected in parallel with a throttle device (11) having at least one porous permeable member (20, 25) communicating in a refrigerant flow direction in a flow path is disposed in a divided intermediate flow path of the evaporator (5, 7), and a gas/liquid two-phase refrigerant is caused to pass through the throttle section. The throttle device (11) comprises an orifice (23), and the porous permeable member (20, 25) is disposed at least at one of upstream and downstream of the orifice (23) in the refrigerant flow direction. A space (22, 24) is defined between the orifice (23) and the porous permeable member (20, 25).
