Abstract:
A bidirectional throttle valve (100), and an air conditioning system (200) having the same. The bidirectional throttle valve (100) comprises a valve pipe (10). A first valve core (22) and the inner wall of a first valve opening (211) fit with each other to form a first circulation channel. A second valve core (32) and the inner wall of a second valve opening (311) fit with each other to form a second circulation channel. When the first valve opening (211) and the second valve opening (311) are opened, the flow area of the first circulation channel is greater than the flow area of the second circulation channel, and the second valve core (32) cooperates with the second valve opening (311) to achieve throttling. The present application further provides an air conditioning system (200) which comprises the bidirectional throttle valve (100).
