摘要： PROBLEM TO BE SOLVED: To solve a problem that in a conventional cooling medium reheating type dehumidifying air conditioner, at passing through a head exchanger, the supersaturated state is released since cooled supersaturated air collides with heated air, water drip occurs and temperature unevenness is generated since blowing-out in the fully mixed state is impossible, or dehumidifying amount is largely affected by arrangement location of the heat exchanger since wind speed of a blower is not even, which greatly restricts design. SOLUTION: The heat exchanger is thermally divided, each of them is made as a heat exchanger for cooling and a heat exchanger for heating, and the heat exchanger for cooling is arranged on the upstream side to an air flow, while the heat exchanger for heating is arranged on the downstream side so that the entire air which has been cooled and dehumidified is reheated evenly.

摘要： PROBLEM TO BE SOLVED: To provide manufacturing method of a centrifugal fan light, facilitating an injection molding work, improving productivity, and reducing a manufacturing cost. SOLUTION: A hollow part molding part 6 to produce a main plate molding part 5 and the hollow part of a blade is placed on a female mold 4, and a main plate forming part 8 and a blade molding part 9 are placed on a female mold 7. Further, a support part 10 is arranged between the protrusion part end face 11 of the hollow part molding part 6 and the retracting part bottom 12 of the blade molding part 9, and the hollow part molding part 6 is supported by the blade molding part 9. This constitution prevents deformation of the hollow molding part 6 in a protrusion shape formed by a pressure exerted during injection molding of a centrifugal fan by a molding tool consisting of the male mold 4 and the female mold 7. Thus, the thickness of the blade is decreased and the weight of the centrifugal fan is reduced, and further, a cooling curing time during an injection molding work is shortened.

摘要： PROBLEM TO BE SOLVED: To increase the quantity of reheat using a condenser during reheating and dehumidifying operation in which one of two indoor heat exchangers is used as the condenser while the other is used as an evaporator. SOLUTION: A refrigerating cycle is provided with a liquid reserving means 10 for reserving extra liquid refrigerant. The liquid reserving means 10 is positioned on the high pressure side, and a liquid reserving means bypass passage 13 which bypasses the liquid reserving means 10 and a pressure reducing means 12, and a cooling means 11 for cooling the refrigerant between a part branching to the liquid reserving means bypass passage 13 and the outlet of the liquid reserving, means 10 are provided. A high-pressure two-phase refrigerant flowing out of an outdoor heat exchanger 7 is cooled and liquefied, with part of the liquid refrigerant reserved in the liquid reserving means 10. Also, the high-pressure two-phase refrigerant is guided via the bypass passage 13 to a condenser 15 which functions as the reheater of an indoor unit 2. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To reduce noise caused by a separation flow of a fin end by providing a rectifying member between a centrifugal fan and a heat exchanger in the vicinity of a center connecting the center of the centrifugal fan casing and the center in the direction of the heat exchanger line in an air conditioner provided with the heat exchanger and the centrifugal fan. SOLUTION: A main body cabinet 1 of an air conditioner is provided with an inlet port 2 and an outlet port 3, and a heat exchanger 4 is incorporated into the main body cabinet 1. In the casing 6 provided on the outside of the inlet port 2 is stowed a centrifugal fan 7. In this case, a rectifying member 9 is provided between the inlet port 2 and the heat exchanger 4 so as to nearly intersect at right angles with the line of flow of air blown from the centrifugal fan 2 in the vicinity of a center C of a line connecting a center A of the outlet port of the centrifugal fan 7 and a center B in the direction of the line of the heat exchanger 4. As a result, velocity of flow reaching the heat exchanger 4 is reduced, a flow intersecting at right angles is relieved, reducing the noise generation caused by a separation flow of the tip of the fin 5.

摘要： PROBLEM TO BE SOLVED: To increase pressure, heighten blowing efficiency and lower noises for a turbo fan or to save energy and lower noises for an air conditioner. SOLUTION: This turbo fan arranges a shroud, a hub and backward curved blades which face reversely to plural rotational directions. In a height direction of an impeller, an impeller rotational direction side surface of the blade has a smooth protruding shape in a rotational direction from an impeller internal circumferential side to the vicinity of the center and a smooth recessed shape in the rotational direction from the vicinity of the center to the impeller internal circumferential side. An impeller rotational direction rear surface is curved such that it has a smooth recessed shape in the rotational direction from at least the vicinity of the center to an impeller outer circumferential side tip of the blades. This turbo fan has a wing-shaped blade section whereof blade thickness gradually increases from an impeller internal circumferential side tip and then gradually decreases to an outer circumferential side tip.
