    摘要: A scroll compressor for compressing a gas to a high pressure or for use in a refrigeration system such as a refrigerator, freezer, air conditioner or the like, is provided. In the compressor, a compressor unit and its driving motor is enclosed gas-tightly in a casing, and the compressor unit is provided with a backpressure chamber into which is introduced a partially compressed gas so as to press an orbiting scroll member against a stationary scroll member. The compressed gas discharged from the compressor unit is circulated through component parts such as the motor enclosed in the casing before it flows into a next stage outside of the compressor. With the above arrangement, the separation of the orbiting scroll member from the stationary scroll member due to the gas pressure is prevented to thereby attaining a secure axial seal between them, and also the motor is satisfactorily cooled.

    摘要: A refrigeration evaporator includes a serpentine refrigerant tube having a plurality of finned straight portions connected by unfinned U-shaped connecting portions to form a stacked assembly of side-by-side finned tube arrays. The fins are rectangular and are provided with a J-shaped cut-out at each corner. The J-shaped cut-outs at confronting corners of the fins of each immediately adjacent pair of finned tube arrays define a U-shaped heater receiving space extending the length of the arrays and which clampingly receives an elongated straight portion of a serpentine electric defroster heater in good heat conductive contact with each fin of the immediately adjacent pair of finned tube arrays. Each fin of the stacked assembly has at least two corners in engagement with the heater. The stacked assembly is disposed transversely in a duct having an air inlet and air outlet. The fins nearest the inlet are spaced at a larger interval than those nearest the air outlet to preclude air flow restriction due to greater frost formation on the fins immediately adjacent the inlet.

    摘要: A humidity control apparatus characterized in that a dehumidifying mechanism, which comprises a refrigeration circuit composed of a compressor, a condenser, a decompression device, and an evaporator, a fan for drawing in air past the circuit, and a tank for collecting and storing the moisture in the condensed form, is combined with a humidifying mechanism comprising an intake duct into which part of the air current is bypassed, taking advantage of the dynamic pressure exerted by the fan, ultrasonic humidifying-vapor generator means wherein the air from the intake duct is mixed with water vapor, and a discharge duct through which the air-vapor mixture is discharged to the outside, said generator means being supplied with water from said tank. The tank has tapped holes at its top and bottom so that, for dehumidification, it serves as a water storage tank with the upper hole kept open and the lower hole closed with a solid plug and, for humidification, it serves as a feed water tank with the upper hole closed by the plug and the lower hole connected with feeder means for water supply to the vapor generator means.
