Improvements in refrigerating systems for cooling air
Реферат: 381,312. Cooling air. MATHER & PLATT, Ltd. and BARCLAY, S. F., Park Works, Manchester. Sept. 11, 1931, No. 25513. [Class 29.] The flow of refrigerant through a heat exchanger a, through which air to be cooled is drawn by a fan g, is controlled by the change in the rate of flow of the air to or from the radiator due to the variation in cross-sectional area of the air passages consequent upon the frosting of the radiator. In one construction, a fan h driven by the air flow drives a centrifugal governor i which operates a tilting switch k controlling electromagnetically a valve f in the refrigerant circuit. The fan h may be replaced by a vane or plate suspended in the air stream and directly connected to switch k. This plate may be supported on knife edges and may be provided with adjusting screws to vary the angle of switch k relatively to it.
