摘要： PROBLEM TO BE SOLVED: To provide an indoor unit for an air conditioner, which is capable of restraining the generation of condensation in the cross flow fan side of a nose at a low cost. SOLUTION: An indoor unit 10 for an air conditioner is provided with a casing 1 and a heat exchanger 2, received in the casing 1. A cross flow fan 3, sending cold air, generated by the heat exchanger 2, into a room, is arranged near the heat exchanger 2. A nose 4 is provided near the cross flow fan 3. A rib 5 is provided at the reverse side of the nose 4 to the cross flow fan 3 so that the cold air, generated by the heat exchanger 2, will not be contacted directly with the nose 4. A projected part 6, formed so as to have a semi- spherical configuration, is provided near the tip end of the nose 4.

摘要： PROBLEM TO BE SOLVED: To simplify manufacture of a cross flow fan and reduce the cost thereof by manufacturing a side wash fan by laminating a plurality of pieces of multiblade impeller in order in an axial direction of the multiblade impeller, which is extracted from a forming mold while rotating around a rotary shaft, and which is erected integratedly by inclining a plurality of blades annually and for a prescribed angle on one surface of a diaphragm. SOLUTION: In the case where a multiblade impeller 26 is manufactured, a resin material is sprayed in a space formed by an upper mold, a lower mold 36, and a base seat 37, and a multiblade impeller 26 is thus formed. After that, the upper mold is separated from the lower mold 36, an ejector shaft is operated so as to deliver the multiblade impeller 26 from the lower mold 36. In this time, an ejector block 35 and the base seat 37 are rotated together with the ejector shaft, and the diaphragm 25 of the multiblade impeller 26 is also rotated. Blades 24 are inclined to a fan shaft, and thereby the multiblade impeller 26 is thus provided. A side swash fan is manufactured by concentrically connecting and fixing each of multiblade impellers 26 which are adjacent to each other in an axial direction in order, for example, by sliding it with a prescribed piece sliding angle in a rotational direction.

摘要： PROBLEM TO BE SOLVED: To provide a water supply controller capable of satisfactorily ensuring water level control of a nuclear reactor upon transition of a change in a nuclear reactor output even when the change is produced. SOLUTION: A flow rate controller control constant alteration part 6 inputs a water level deviation ΔH being an input signal of a main controller 3, a flow rate deviation ΔQ being a deviation between a water supply instruction Qr and a supply water flow rate Q, a selective control rod insertion signal SRI, a trip signal Tr of a recirculation pump, a run-back signal B of the recirculation pump, and the operation number Pn of water supply pumps 5, and judges, based upon any one or two sets of these signals, whether or not the control becomes a transient operation state where a nuclear reactor water level might reach a low water level setting or high water level setting. When the alteration part 6 judges that the control would become such transient operation state, it outputs a control constant suitable for such transient operation state to alter a control constant of the flow rate controller 4.

摘要： PROBLEM TO BE SOLVED: To reduce the noise of a transverse flow fan by laying out a heat exchanger so that the longitudinal axis of the heat exchanger may be twisted to a rotary shaft of the transverse flow fan. SOLUTION: An indoor heat exchanger 29 is laid out as opposed to a skew transverse flow fan 30 so that a central axis OC of each straight running part 37a of an electric heating tube 37 and a central axis Od of the skew transverse flow fan 30 may be twisted to each other. More specifically, when it is viewed from the right angle direction of draft, they may be opposed to each other in V shape and in non-parallel. During the operation of the skew transverse flow fan 30, an after flow from each transfer tube 37 of the heat exchanger 29 is sucked up into the skew transverse flow fan 30. When it is collided against each skew blade, a pitch sound is generated, but the indoor heat exchanger 29 is laid out so that the longitudinal axis of the straight running part 37a of the heat transfer tube 37 may be located in a twisted position with the central axis Od of the skew transverse flow fan 30. This construction makes it possible to reduce a blade pitch sound by deviating the generation cycle of the blade pitch sound of the transverse flow fan to the axial direction.

摘要： PROBLEM TO BE SOLVED: To enhance reliability of a refrigeration cycle by decreasing the r.p.m. of a compressor before decreasing the r.p.m. of the condenser and a fan and preventing over pressure rise on the high pressure side thereby suppressing abnormal stop of a compressor, and the like, or release control. SOLUTION: A control section 31 performs general control of an air conditioner and a second speed control circuit 30 sets the rotational speed of an outdoor fan motor 8M at a level corresponding to a command from the control section 31 at the time of power supply voltage control for the motor 8M. A first speed control circuit 29 sets the rotational speed of an indoor fan motor 4M at a level corresponding to a command from the control section 31 at the time of power supply voltage control for the motor 4M. An indoor tan control means 31a at the control section 31 decreases the r.p.m. of a compressor 2 before the r.p.m. of an indoor tan 4 for main and sub-indoor heat exchangers 5, 6 serving as a condenser at the time of heating operation is decreased.

摘要： PROBLEM TO BE SOLVED: To improve the operability in interlocking the air-conditioning operation and the air cleaning operation by continuing the energization condition of a dust collector when the air-conditioning operation is started while an electric dust collector is operated, and simultaneously stopping the energization of a dust collection electrode when the air-conditioning operation is stopped. SOLUTION: A remote control device 10 is provided with display part 11 on an upper part, a first button 12 for air-conditioning operation and an air cleaning button 13 are continuously arranged on a lower part, and an air volume button 14 for regulating the air volume is arranged in an area therebelow. Even when the air-conditioning operation is started while run electric dust collector is operated, the energization condition of a dust collection electrode is continued, the energization of the dust collection electrode is simultaneously stopped when the air-conditioning operation is stopped, and the operability can be improved when the air-conditioning operation is interlocked with the air cleaning operation. After the prescribed time is elapsed according to the operation frequency of the air cleaning button 13, or the silent energy- saving operation is achieved from the beginning of the operation, and the dust collection performance can be improved unless a user achieves any special setting by appropriately changing the air direction and volume.
