    摘要： The present invention provides a refrigeration cycle apparatus using a first compressor and a second compressor driven by an expander and including a high and low pressure heat exchanger, in which a low-pressure-side outlet of the high and low pressure heat exchanger is bypassed to a low pressure portion or an intermediate pressure portion to adjust an inlet density at the expander and thereby provide high efficiency. The high and low pressure heat exchanger of the refrigeration cycle apparatus of the present invention changes an amount of heat exchange between a high-pressure refrigerant and a reduced-pressure refrigerant branched from the high-pressure refrigerant at an inlet portion of the high and low pressure heat exchanger and reduced in pressure to adjust the density of the refrigerant flowing in the expander so that power recovered by the expander and power required by the second compressor match.

    摘要： A heat exchanger includes a primary heat exchange portion and a secondary heat exchange portion. The primary heat exchange portion includes first primary fins provided parallel to a direction in which a fan sends air, first primary pipes that are inserted into the first primary fins and through which refrigerant flows, second primary fins positioned windward of the first primary fins and provided parallel to the direction in which the fan sends air, second primary pipes that are inserted into the second primary fins and through which the refrigerant flows, and a primary-pipe connecting component extending in a direction parallel to the direction in which the fan sends air, and connecting one of the first primary pipes and one of the second primary pipes. The secondary heat exchange portion includes first secondary fins provided parallel to the direction in which the fan sends air, first secondary pipes that are inserted into the first secondary fins and through which the refrigerant flows, second secondary fins positioned windward of the first secondary fins and provided parallel to the direction in which the fan sends air, second secondary pipes that are inserted into the second secondary fins and through which the refrigerant flows, and a secondary-pipe connecting component extending in the direction parallel to the direction in which the fan sends air, and connecting one of the first secondary pipes and one of the second secondary pipes. When the heat exchanger acts as an evaporator, the refrigerant flows through the primary heat exchange portion from the first primary pipes toward the second primary pipes and the refrigerant flows through the secondary heat exchange portion from the second secondary pipes toward the first secondary pipes. When the heat exchanger acts as a condenser, the refrigerant flows through the primary heat exchange portion from the second primary pipes toward the first primary pipes and the refrigerant flows through the secondary heat exchange portion from the first secondary pipes toward the second secondary pipes.

    摘要： It is intended to realize an air conditioning system of high operational efficiency without reducing the user's comfort. In an air conditioning system 1, a set temperature determining device 31 determines a target temperature of water to be supplied to an indoor heat exchanger 12, based on ["target outflow temperature" = "current outflow temperature" + (("inlet and outlet temperature difference" / "indoor and outdoor temperature difference") × "set temperature difference")]. The indoor and outdoor temperature difference is a difference between an indoor temperature and an outdoor temperature, the inlet and outlet temperature difference is a difference between temperatures of water at the inlet side and the outlet side of an intermediate heat exchanger 9, and the set temperature difference is a difference between an indoor temperature and a set temperature. A control device 32 controls an outdoor unit 2 in response to the target temperature determined by the set temperature determining device 31.
