<p>PURPOSE:To efficiently and individually measure the calorific value of waste heat of each house for feeding back merits corresponding to the drain calorific value to each house by controlling in a concentrated manner the opening, or closing of drain valves of supply hot water using equipments of each house, timely controlling drain to a waste heat recovering tank to measure drain calorific values using a single calorimeter. CONSTITUTION:A computer 7 makes up a schedule of opening or closing of a solenoid valve 4 of each house when discharges of residual hot water are centralized with time, on the basis of intention of each house to discharge residual hot water through a switch 6 from each house. The computer 7 transmits a hot water discharge refusing signal to a valve controller 8 from a time where the switch 6 is turned on, along the schedule, and discharge of residual hot water is delayed. Further, when the residual hot water discharges are not centralized, warm drain is discharged along the intention of the residual hot water discharge. The discharged drain is measured by the calorimeter 5, and the value is recorded in the computer 7 and the integrated value thereof is calculated. By the above-described method, it is possible to measure individually the drain calorific values of respective house holds.</p> |
