PURPOSE: A heat pump system with counter flow is provided to increase heat exchange efficiency in both cooling and heating modes using counter flow and reduce energy loss using heat sources like geothermal heat and river water. CONSTITUTION: A heat pump system with counter flow comprises a heat pump unit(30), a heat source supply line(20), and a cold and hot water line(25). The heat pump unit comprises a first heat exchanger(31), a second heat exchanger(32), and a reversing valve(35). The first heat exchanger exchanges heat with heat sources(1) including geothermal heat and river water. The second heat exchanger is connected to the first heat exchanger through a refrigerant line(50). The reversing valve in the refrigerant line changes flow of the refrigerant. The heat source supply line is connected to between the first heat exchanger and the heat source and extended that heat exchange media is circulated. The cold and hot water line is connected to between the second heat exchanger and a destination(2) or a cold and hot water storage tank(3) and extended that cold and hot water is circulated. |
