<p>It is an object of the present invention to provide an air conditioner preventing occurrence of chattering even when a refrigerant, changed into liquid in a radiant heat exchanger, resides in the vicinity of the radiant heat exchanger and an open/close valve during a heating operation. In an air conditioner (1), a first check valve (42) is disposed between a radiant heat exchanger (14) and an open/close valve (41). When the open/close valve (41) is closed, less liquid refrigerant exists between the open/close valve (41) and the first check valve (42). Even when the liquid refrigerant spontaneously evaporates and the internal pressure is increased, the internal pressure is not increased enough to push and open the open/close valve (41). Occurrence of chattering is thereby prevented.</p> |
