| (54) | Air conditioner |
| (57) Disclosed is an air conditioner including a plurality of compressors (2) (8) compressing
a refrigerant, a first heat exchanger (10) for condensing the refrigerant compressed
in the compressor (2), a first expansion valve (40) for expanding the condensed refrigerant,
a second expansion valve (42) for expanding the refrigerant emerging from the first
expansion valve (40), a second heat exchanger (12) for evaporating the refrigerant
emerging from the second expansion valve (42). The refrigerant from the first expansion
valve (40) is guided such that a portion of the refrigerant is introduced into one
of the compressors (2) (8) after bypassing the second expansion valve (42) and second
heat exchanger (12), and a remaining portion of the refrigerant is introduced into
another one of the compressors (2)(8) after passing through the second expansion valve
(42) and second heat exchanger (12), to minimize electric power consumption and to
enhance heating performance.
