Title: Averaging temperature differences between reference and ambient temperatures
IPC: G01K3/04
Filed: 1981-06-04
Abstract: Assessment of space heating energy requirements is made by the measurement of "degree-days". That is, the difference between a reference temperature and the average over 24 hours of ambient temperatures below the reference temperature. A temperature transducer (1) gives a signal related to ambient temperature which is passed through an input circuit (2) producing a voltage signal related to the difference between the reference temperature and the ambient temperature only when the former is the greater. A voltage to frequency converter (4) converts the voltage signal to a frequency signal which is counted in a decade counter (6) for a 24 hour period determined by a signal derived from a quartz crystal oscillator (8), thus allowing calculation of the "degree-day". <IMAGE>
