Abstract

972,077. Air conditioning. CARRIER CORPORATION. Feb. 9, 1961 [May 5, 1960], No. 4926/61. Heading F4V. [Also in Division G3] An induction unit for an air conditioning system is supplied with primary conditioned air which is discharged through nozzles to induce secondary room air over a heat exchanger and/or through a by-pass channel which is damper controlled in accordance with the secondary air temperature. Primary air is supplied to a plenum chamber 26 whence it flows through a damper controlled aperture 29 to discharge nozzles 28, separate secondary streams of air being induced to flow through an inlet 37 at the base of the unit and through a further inlet 71 to a control 68 at the side: of the unit. A heat exchanger 32 is mounted in the lower part of the unit and is by-passed by a passage 33 formed by a wall 34 the upper part 40 of which is hinged at 41 to form a damper which is biased towards a position closing the passage by a counter-weight 43. The plenum chamber 26 communicates via a line 51, filter 52, pressure equalizer 54 and an orifice 57 with lines 59 and 60 which lead to a bellows 39 attached to the damper plate-40 and a changeover valve 61 respectively. The valve 61 is controlled by. a thermostat 62 to connect line 60 to either line 66 or line 67 depending on whether heating or cooling medium is being circulated through the heat exchanger 32 and bimetallic elements 74 and 73 are mounted at the ends of the respective lines. When the line in use is covered by the appropriate element the pressure in the bellows 39 rises and the damper plate 40 is moved to open the by-pass passage 33; conversely air is bled from the pipe when the element 1 uncovers its end in accordance with the temperature of the secondary air induced through the inlet 71 and the bellows pressure drops to close passage 33. In the complete air conditioning system units of the above type are positioned in various rooms of a building and are supplied with primary air from a central conditioning unit comprising a filter, pre-cooling coil, humidifier, a heating coil and a cooling coil. Specification 641,712 is referred to.
