Abstract: A movable valve element is provided so as to rotate about a predetermined shaft center. A first valve seat and a second valve seat are respectively arranged apart from the movable valve element with predetermined clearances on both sides of the movable valve element in a direction along the shaft center. A first sealing member is arranged around a communication path so as to seal a space inside the communication path from a space defined by the clearance on a side close to the first valve seat. A second sealing member is arranged around the communication path so as to seal the space inside the communication path from a space defined by the clearance on a side close to the second valve seat.

Abstract: A heat pump system includes a heat pump circuit, a heat load circuit, first and second heat exchangers, a flow rate adjustment element, and a controller. The heat pump circuit circulates primary refrigerant through a low and high stage-side compression elements, an expansion element and an evaporator. The heat load circuit circulates a first fluid and has a first and second branching portions, first and second branching channels, and a heat-load-processing section. The first and second heat exchangers perform heat exchange between the primary refrigerant and the first fluid. Flow rate of the first fluid in the first and/or second branching channel is adjustable. The controller performs flow rate adjustment control so as to maintain a state in which a predetermined temperature condition is satisfied, or to reduce a difference between the temperature of the first fluid flowing through portions of the first and second branching channels.

Abstract: A cooling member includes a heat-transfer member having a groove and a refrigerant introducing pipe pressed into the groove. The refrigerant introducing pipe has a pressed region positioned inwardly of the edge of the heat-transfer member, and at least one curbed surface portion. A method for manufacturing a cooling member includes preparing a punch having at least one curved corner and a pressing surface, positioning the corner, and moving the punch closer to the groove to press the refrigerant introducing pipe into the groove with the pressing surface. A device for manufacturing a cooling member includes the punch and a support configured to support the heat-transfer member so the groove is positioned opposite the punch.

Abstract: An air conditioner includes a printed circuit board (31) to which a power device (33) is attached; and a refrigerant jacket (20) which is connected to the power device (33), and through which refrigerant used for a refrigeration cycle flows. The printed circuit board (31) is accommodated in a switch box (40). The refrigerant jacket (20) is fixed to the switch box (40) through a heat transfer plate (50), and the refrigerant jacket (20) and the printed circuit board (31) are connected together by the switch box (40).

Abstract: A printed-circuit board (31) having a power element (33) and a refrigerant jacket (20) to which the power element (33) is thermally connected, with refrigerant circulating therein used in refrigeration cycle, are provided in an outdoor unit casing (70). The printed-circuit board (31) is provided in a switch box (40). A face of the outdoor unit casing (70) has a service opening (71). The refrigerant jacket (20) faces the service opening (71), being closer to the front side of the outdoor unit casing (70) than the power element (33) as viewed from the service opening (71).

Abstract: An air inlet 16 is formed in a rear surface side vertical wall section 10b, or a single surface of an apparatus main body 10, and an air stream path that extends from the air inlet 16 of the rear surface side vertical wall section 10b to air outlets 14a and 14b formed upwardly aslant in an inclined surface section 13 that is also the single surface provided in the opposite direction. In this air stream path are arranged an air-cooling absorber 17, an air-cooling condenser 19 and fans 15a and 15b provided with their fan axes arranged upwardly aslant in correspondence with the air outlets 14a and 14b. With this arrangement, the air-cooling absorption type refrigerating apparatus is made to have an integrated air intake space and a reduced installation area, and an air stream path extending from the air inlet to the air outlets is made to have a reduced draft loss to allow the flow velocity distribution of the air stream of the heat exchange section to be uniformed.
