In the second connection state, the refrigeration cycle apparatus repeatedly performs a second cycle in which refrigerant flows through the compressor, the second heat exchanger, the first heat exchanger, and the compressor in that order. In the third connection state, a passage between the compressor and the first heat exchanger and a passage between the compressor and the second heat exchanger are closed, and the first channel in the refrigeration cycle apparatus provides interconnection between the first heat exchanger and the second heat exchanger.

Abstract: A heat-source-side heat exchanger is divided so that a heat-source-side heat exchanger that functions as an evaporator also functions as an intermediate cooler. Since, when an air conditioner includes a bypass pipe, a heat-source-side heat exchanger that functions as an evaporator and as an intermediate cooler also further functions as a radiator, operation efficiency is increased.

Abstract: A paper sheet handling apparatus includes: a first stopper that is in contact with a first partition at a lower limit position of the first partition; and a pressing portion that is fixed to a second partition and raises and lowers the first partition integrally with the second partition using a frictional force generated by pressing a guide. The second partition descends integrally with the first partition, and after the first partition comes into contact with the first stopper, the second partition descends independently of the first partition against the frictional force to a position where the pressing portion faces the recessed portion that cancels the frictional force. The second partition, when ascending from the position where the pressing portion faces the recessed portion to a position where the pressing portion no longer faces the recessed portion, ascends integrally with the first partition due to the frictional force.
