Air conditioning apparatus

摘要

An air conditioning apparatus is disclosed having a refrigerating cycle, in which a compressor (1), an outdoor heat exchanger (3), a first flow control valve (4), a first indoor heat exchanger (5), a second flow control valve (6), and a second indoor heat exchanger (7) are sequentially connected. A support member (215) is rotatably disposed in a valve main body of the second flow control valve (6) and having at least one small hole (212) for throttling a refrigerant flow. At least one porous permeable member (211) is disposed in the vicinity of the small hole (212) so as to form a throttle section integrally therewith for rectifying a refrigerant passing through the small hole (212). Switching is effected between a first case in which the first indoor heat exchanger (5) is caused to communicate with the second indoor heat exchanger (7) through the throttle section composed of the porous permeable member (211) and the small hole (212), and a second case in which the first indoor heat exchanger (5) is caused to communicate with the second indoor heat exchanger (7) through the inside of the valve main body bypassing the throttle section by rotating the support member (215) in the main valve body of the second flow control valve (6).
