Document Type and Number:
WIPO Patent Application WO/2012/077275
Kind Code:
A1
Abstract:
Provided is an air-conditioner (10), the cooling medium circuit (20) of which is equipped with a compressor unit (30), an evaporator (50), and an electromagnetic valve (70) that constitutes a circulation control mechanism (17). The operating capacity of the compressor unit (30) is adjusted by changing the number of compressors (31, 32, 33) which are operating. The evaporator (50) is provided with a first heat exchange unit (55) and a second heat exchange unit (60). A first circulation path (56) of the first heat exchange unit (55) and a second circulation path (61) of the second heat exchange unit (60) are mutually connected in parallel. When the electromagnetic valve (70) is open, cooling medium flows in both the first circulation path (56) and the second circulation path (61). When the electromagnetic valve (70) is closed, cooling medium flows in only the first circulation path (56).
