Abstract
563,195. Thermostats; refrigerating. DEHN, F. B. (Mills Novelty Co.). Jan. 27, 1943, No. 1396. [Classes 29 and 64 (ii)] In a thermallyoperated valve for controlling the cooling water in a compression refrigerating apparatus actuated by vapour pressure in a thermally sensitive bulb connected to a responsive element such as a bellows, undue condensation of vapour in the bellows and loss of liquid from the bulb, is prevented by keeping the bellows temperature above that of the bulb. In Fig. 1, refrigerant from a compressor 10 is cooled by water in a counter-flow condenser 11, and passes into a liquid receiver 12 and thence through an expansion valve 16 into an evaporator 17. Cooling water, after passing through the condenser 11, passes through pipe 19 to the water jacket of the compressor 10. The flow of cooling water leaving the compressor is controlled. by valve 26, Fig. 3, carried by bellows 28 to which vapour pressure is transmitted by pipe 31 from bulb 30. The bellows is heated by a jacket 34 through which passes the hot gas delivered by the compressor. Alternatively, the bellows may be heated electrically by a surrounding coil, or by a jacket through which water from the compressor jacket passes. The control valve 26 may be on the inlet side of the compressor jacket.
