Title:
HEATING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/122922
Kind Code:
A1
Abstract:
A heating system provided with a hot-water storage tank (20), a heater core (35), a duct (36), and a defrosting requirement determining unit. The hot-water storage tank stores supply water which has been heated by a heat pump cycle (10). A high-temperature-side heater core heats the supply air flowing out of a ventilation heat exchanger (34) using the supply water stored in the hot-water storage tank (20) as a heat source. A duct (36) guides discharge air flowing out of the ventilation heat exchanger (34) toward an evaporator (14) of the heat pump cycle (10). The defrosting requirement determining unit determines whether or not there is a need to defrost the evaporator (14). If it is determined that there is a need to defrost the evaporator (14) and the heat quantity (Qt) of the supply water stored in the hot-water storage tank (20) is equal to or greater than a reference heat quantity (KQt), the operation of the compressor (11) of the heat pump cycle (10) is stopped.
