Title: Improvements in or relating to temperature control systems
IPC: G05D23/24
Filed: 1943-08-06
Abstract: 573,028. Electric temperature control systems. VUILLE, B. A., and WATFORD ELECTRIC & MANUFACTURING CO., Ltd. Aug. 6, 1943, No. 12759. Addition to 540,087. [Class 40 (i)] [Also in Group XXXV] Temperature.-A system of temperature control for a building as claimed in the parent Specification, is adapted to vary the heat supplied with variations in outside temperature according to one of a number of related laws and has means responsive to the inside temperature which adjusts the system to operate upon a different one of those laws, when the inside temperature differs from that desired. Fig. 2 for example shows a curve 26 representing such a law. The present invention provides means whereby the slope of such a curve may be varied, for example to the curve 30, and so reduce the operation of the inside temperature control in correcting for an initially provided law which does not suit the conditions in the building. Fig. 1 shows a resistance bridge to which a galvanometer or polarized relay G is connected to operate through a relay system 29, a reversible motor 12 adjusting a valve 11 controlling the supply of heating fluid. The bridge comprises fixed resistances R1, R2, a resistance Re responsive to temperature outside the building and a resistance Rf which varies or is varied in accordance with the temperature or adjustment of the heating fluid supplied. The variation in height of the law (curve 26) is effected by a potentiometer R7 which varies an auxiliary potential in series with the galvanometer G and is operated by means 29 responsive to inside temperature. A potentiometer R5 is connected to the junction of fixed resistances R3, R4 in an additional branch of the bridge and to the junction 17 of resistances R1. Re. Adjustment of the tapping 18 on this potentiometer will alter the slope of the law, for example to a curve such as 30. A manual adjustment of a further potentiometer R6 or of the thermostat 25 will change the height of the curve. Resistances Re, Rf may be interchanged with modified results. Fig. 3 (not shown) shows a modification in which the potentiometers R6, R7 are incorporated in the bridge itself.
