(54) | Refrigeration cycle system |
(57) The present invention relates to a refrigerant cycle system including a compressor
(1), a condenser (2), a depressurizing means (4) and a evaporator (3) which are connected
in series with each other to form a refrigerant circulation circuit. The refrigerant
cycle system includes a heat exchanging portion (11). The heat exchanging portion
(11) exchanges heat between a part of or all of the refrigerant passing through a
refrigerant passage (5) from the compressor (1) to a depressurizing means (4) by way
of the condenser (2) and a part of or all of the refrigerant passing through a refrigerant
passage (6) from the depressurizing means (4) to the compressor (1) by way of the
evaporator (3). |
