Abstract: 408,748. Air conditioning. WING- FIELD, B. R., Brooklyn, The Green, West Drayton, Middlesex. Dec. 20, 1932, No. 36081. [Class 137.] In an air conditioning plant in which the air is humidified and heated before being delivered to a room or enclosure, means are provided whereby the saturation of the air at the required dew point does not start until the set room temperature is reached, thus preventing deposition of moisture due to the entry of warm humidified air into a comparatively cold room. The temperature of the air delivered is also arranged not to fall below comfort limit, irrespective of whether a thermostat in the room calls for heat or not. The plant comprises an air heater 4 controlled by a valve 1 having two diaphragm chambers 2, 3 connected to thermostats 8, 15 in the air conduit and room respectively. Thermostat 15 maintains pressure in chamber 3 which keeps valve 1 closed, and the incoming air cool, and unable to take up moisture until the desired room temperature is reached, when thermostat 15 releases the pressure from chamber 3, and allows valve 1 to work under control of thermostat 8. An air re-heater 9 is controlled by a valve 10 actuated from two diaphragm chambers 11, 12 connected to thermostats 13, 14 in the air conduit and room respectively. Should the thermostat 14 be subject to local heating, the temperature of the heater 9 is not reduced, as the thermostat 13 has a master control and prevents the entry of air which is cold below the limit of comfort. The heater 4 and humidifier 5 may be replaced by a humidifier supplied with heated water.
