468,484. Conditioning air. CORNELL, E. S. Aug. 10, 1936, No. 22040. Convention date, Aug. 10, 1935. [Class 137] Rooms or spaces 10, 11 to be ventilated and heated or cooled, are provided with heat exchange devices 12a-15a, and fans 17, 19, 31, 35 driven by air-pressure motors, such as described in Specification 403,584, [Group XXVI]. Motor 16 is connected by pipes 20, 21 to a reservoir 23 supplied by a compressor 22, and the compressed air used is delivered into the room. Motor 18 is connected by pipes 25, 26 to a reservoir 27 connected to the suction side of the pump 22 so that the motor withdraws air from the room 10 for its operation, and discharges it at lower pressure to the reservoir 27. The room 11 is heated or cooled and ventilated in a similar manner. Air-cleaning and/or humidity controlling devices may be associated with the tanks 23, 27, and connections for the circulation of fresh air may be provided at 36, 38. The heatexchanger 41 for heat-treating the air supplied to the system is associated with a fan 40. Specification 457,387 also is referred to.
