PURPOSE: A heating system and a control method thereof are provided to increase the temperature of hot water because the quantity of refrigerants heat-exchanged in a load heat exchanger increases and the temperature secondary fluids of the load side increases. CONSTITUTION: A heating system comprises a refrigerant line(L100), a load line(L300), a heat source line(L200), a refrigerant bypass line(L110), and an auxiliary heat exchanger(160). Refrigerants circulates through a compressor(110), a load side heat exchanger(130), an expander(140), and a heat exchanger of a heat source side(150). Secondary fluids of the heat source side pass the heat exchanger of the heat source side through the heat source line, and the refrigerant bypass line bypasses some refrigerants from a compressor outlet. The refrigerant bypass line directly or indirectly increases the temperature and pressure of the refrigerants flowing into the compressor. The auxiliary heat exchanger heat-exchanges the refrigerants passing through the load side heat exchanger with the secondary fluids of the heat source side. |
