Title:
Air-conditioner
Document Type and Number:
Japanese Patent JP6017049
Kind Code:
B2
Abstract:
When a first heat exchanger, namely a heat-source-side heat exchanger (12), is acting as a condenser, this air conditioner is controlled such that, as a refrigerant flows through a first bypass pipe (4a) to an inflow-side pipe for an accumulator (15) via throttling devices (14a and 14d), said refrigerant also flows through a second bypass pipe (4b) via one of the throttling devices (14b) and is introduced into a channel between a compressor (10) and the accumulator (15). When the heat-source-side heat exchanger (12) is acting as an evaporator, the air conditioner is controlled such that the refrigerant flows through the second bypass pipe (4b) via the aforementioned throttling device (14b) and is introduced into the channel between the compressor (10) and the accumulator (15) and the other throttling device (14d) is either closed completely or closed down such that almost no refrigerant flows therethrough.
