Catalog 13: Carrier air washers and humidifiers: applied to public office and industrial buildings, with notes on humidity . the connection E, to the annular chamber, between theinner and outer tubes. As the outer member expands, thevalve recedes from its seat, allowing the compressed air toescape into outlet connection G, which connects with thediaphragm valve controlling the temperature of the spray water,thus moving the valve so as to reduce the temperature of thedew point. When the dew point temperature falls below thepoint desired, the outer member contracts, closing off the airsupply to the diaphragm valve, connected to G, and the airpressure to the diaphragm motor is released through the ad-justable vent. This vent allows an air leak varying with thepressure on the diaphragm motor. Therefore, the relation ofthe area of opening through the valve G to the constant areaof the vent opening G determines the graduated pressure onthe diaphragm motor at any instant. This thermostat issensitive while positive in action and simple in construction. 56 Carrier Air Conditioning Company _ of America -WATER INLET E. WATER OUTLET F Carrier Noiseless Ejector Water Heater Ejector Water Heater: The common difficulty usu-ally experienced in the heating of water by an automatically con-trolled ejector is the noise produced when very little steamis being used. This noise is a water hammer occurring whena reduced amount of steam at low velocity enters a largevolume of water and suddenly condenses. This causes apartial vacuum, which the water immediately fills, producingan impact which forces the valve against its seat. The design of the heater shown above prevents the ham-mering of the valve. The diaphragm steam valve is madea part of the heater. The steam enters at A through thevalve B into the chamber C; then through the orifice D. Thewater enters at E and passes out at F. The opening throughthe orifice D varies with and is approximately equal to the open-ing of the valve B for a
