Process and device to calculate heating costs by electronical gauging of the quantities of heat used during registration periods by individual consumers

摘要

In a heating cost apportioning device, a signal delivered by an evaulation circuit is integrated to produce a measured value integral with respect to time (counters 9, 10). At least two resettable memories (12, 13) are provided for each consumer. A time-controlled control unit (8) controls the evaluation circuit, the integrator (counter 10) and also the first and the second memory (12, 13) in such a way that the up-to-date measured value signal produced during a registration period is always stored in one of the two memories (12) and the due-date measured value integral reached at the end of said registration period remains stored at least until the end of the subsequent registration period. During said subsequent registration period, the other memory (13) of the two memories accumulates in turn the up-to-date measured value signal of this subsequent measured value period.
