摘要： PROBLEM TO BE SOLVED: To provide a duct-type air conditioner at a lower price, by avoiding the complication of the assembly line and the increase of the cost. SOLUTION: Since a control plate 11 can be attached both obversely and reversely, at the time of assembly the control plate 11 is set first, with its obverse directed outward of a casing 1, and at installation work, the control plate 11 is reset, changing its direction, as occasion demands. This way, this air conditioner can change its specification easily to either the structure of allowing access to a control box from outside the casing 1 or the structure of allowing access to it from inside the casing.

摘要： PURPOSE: To minimize the amount of a gas refrigerant entering an upper space in a container and reduce a flow rate of the gas refrigerant an inlet tube by opening an inlet tube and an outlet tube into the upper space above a liquid refrigerant stored at a lower part in the oblong container and connecting a bypass tube allowing only the gas refrigerant to flow therethrough to both the inlet tube and the outlet tube. CONSTITUTION: An inlet tube 10 and an outlet tube 11 of an accumulator 8 are connected to each other in the vicinity of a container 81 by a bypass tube 12 allowing only a gas refrigerant to flow therethrough. By means of this connection, the gas refrigerant is partly diverted at a diverting part where the inlet tube 10 is connected to the bypass tube 12, and only a part of the gas refrigerant thus diverted passes through the bypass tube 12 to flow into the outlet tube 11 while the remaining gas refrigerant accompanied with the mist of a liquid refrigerant enters an upper space 82 of the accumulator 8. As a result, a small amount of the gas refrigerant flows into the container 81. Accordingly, a flow rate of the gas refrigerant also becomes slow, and the mist 83 of the liquid refrigerant is efficiently separated from the gas refrigerant in the upper space 82 to be dropped under its own weight and to be stayed on the bottom of the container 81. Therefore, only the gas refrigerant can be sucked into the outlet tube 11.

摘要： PURPOSE:To raise the temperature of the low temperature drain by high pressure and high temperature coolant and prevent the moisture in the atmosphere from dew condensing on the outer faces of a drain discharge pipe by inserting in the drain groove of a drain pan located below a heat exchanger a high pressure coolant piping that is connected to the heat exchanger. CONSTITUTION:With the air conditioner, a ceiling panel 8 that faces the inside of a room 9 is installed at the lower section of a case main body 2 buried in the ceiling 1. And when a blower 6 is driven by a motor 5 during the operation, the air in the room 9 goes from the suction port 3 to a heat exchanger 7, and the conditioned air here cooled or heated is blown out from a blow-out port 4 into the room 9. At this time the drain generated during the cooling drops down into a drain pan 10 and then is discharged through a drain groove 10a. In this case a high pressure coolant piping 2 that is connected to the heat exchanger 7 is inserted into the drain groove 10a. With this arrangement the temperature of the low temperature coolant in the drain groove is raised by the high pressure, high temperature coolant in the high pressure coolant piping 21, and the dew condensation of the moisture is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a hollow rotating shaft simplifying the processing and reducing the possibility of producing articles out of tolerance by reducing parts securing fitting tolerance as many as possible and by decreasing the diameter of the other parts than the same to roughen the tolerance, and to provide an air blowing device using the same.SOLUTION: In the hollow rotating shaft 6, a shaft part 13 journaled by a bearing is pressed in an end 16 of a hollow shaft 12, and a body to be rotated is installed to an outer peripheral part 14 of the hollow shaft 12 by fitting. The end 16 of the hollow shaft 12, in which the shaft part 13 is pressed, is processed to have a diameter narrower by a predetermined dimension than the outer peripheral part 14 of the hollow shaft 12 to which the body to be rotated is installed by fitting. Relative to the outer diameter tolerance of the outer peripheral part 14 of the hollow shaft 12 to which the body to be rotated is installed, the outer diameter tolerance of the end 16 of the hollow shaft 12, in which the shaft part 13 is pressed, is roughened.
