摘要

Refrigeration cycle apparatus comprising: a compressor (l), a condenser (4), an expansion means (l2,l3) and an evaporator (7) connected in series with each other; means for repeatedly starting and stopping said compressor (l); and means (2,l4) for isolating refrigerant on a high pressure side of said compressor (l) from said refrigerant on a low pressure side of said compressor (l) when compressor (l) is stopped characterised in that said expansion means comprises at least two capillary tube portions (l2,l3) and in that valve means (l5) is connected across one portion (l3) whereby the effective length of said expansion means may be changed.
