Title:
HEAT SOURCE UNIT POWER CONSUMPTION PRORATING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/080804
Kind Code:
A1
Abstract:
Disclosed is a heat source unit power consumption prorating system (10) having a heat quantity usage calculation unit (19a), a corrected heat quantity calculation unit (19b), and an electric power prorating unit (19c). The heat quantity usage unit (19a) calculates a utilization-side heat quantity usage in utilization units (5a, 5b) on the basis of the flow rate and the temperature of a water medium. The corrected heat quantity calculation unit (19b) corrects the utilization-side heat quantity usage in the respective utilization units (5a, 5b) on the basis of the refrigeration cycle characteristics of utilization-side refrigerant circuits (50a, 50b), which are estimated by a heat source-side condensation temperature, or a utilization-side evaporation temperature and a water medium outlet temperature. The electric power prorating unit (19c) prorates the power consumption of a heat source unit (2) in accordance with the corrected utilization-side heat quantity usage.
