Abstract: An integrated type air conditioning device includes a first refrigeration cycle that is an evaporative cooling type, a second refrigeration cycle that is a vapor-compression type, a blower device, and a housing accommodating the first and second cycles. The first refrigeration cycle includes an evaporation heat exchanger, a condensation heat exchanger, and a first refrigerant pipe. The second refrigeration cycle includes a compressor, a condenser, a decompression device, an evaporator, and a second refrigerant pipe. The housing is partitioned into an interior air passage and an exterior air passage. The evaporation heat exchanger and the evaporator are positioned in the interior air passage, the evaporation heat exchanger being located upstream of the evaporator with respect to an interior airflow in the interior air passage. The blower device is disposed in the interior air passage and is driven to generate the interior airflow in the interior air passage.

Abstract: A swing member is supported by a swing support member like a universal joint of a Hook's type such that it can swing in a state where it is prevented from rotating around a center line. In this manner, even if a shaft rotates at high speed, the swing member is surely prevented from rotating around the shaft. Therefore, it is possible to prevent a piston from excessively vibrating, hence to prevent large noises from being made, and to improve reliability and durability of a compressor when the compressor is operated at high speed.

Abstract: A variable displacement compressor includes a linking groove, which forms a hinge for connecting an arm and an inclining member. The groove is generally U-shaped (open). A link pin is fitted in the groove such that the link pin can pivot or slide within the groove. As a result, installation of a movable parts assembly, which is done by inserting the link pin into the groove, is easier. A controlled pressure chamber improves the response of the compressor to controls.

Abstract: A heat pump cycle system which can switches cooling operation and heating operation for a compartment includes a first inside heat exchanger and a second inside heat exchanger disposed in an air conditioning case. The first inside heat exchanger is disposed in the air conditioning case at a downstream air side of the second inside heat exchanger, while being arranged in line in a flow direction of refrigerant. The first inside heat exchanger is upstream from the second inside heat exchanger in the flow direction of refrigerant during the heating operation. In the heat pump cycle system, an expansion valve is controlled so that coefficient of performance in each operation becomes approximately maximum. Thus, during the heating operation of the heat pump cycle system, a lower limit temperature of air blown from the inside heat exchangers can be increased so that temperature of air blown into the compartment is increased, while the coefficient of performance is improved.

Abstract: The supercritical refrigerating circuit has a first pressure reducing valve for reducing pressure of refrigerant flows into a first evaporator and a second pressure reducing valve for reducing pressure of refrigerant flows into a second evaporator. The first pressure reducing valve further controls refrigerant pressure at an outlet of a gas cooler. Accordingly, the supercritical refrigerant circuit is controlled without increasing the number of the pressure reducing valve.
