REGENERATIVE HEAT PUMP UNIT USING GEOTHERMICS

摘要

The present invention relates to a heat storage heat pump unit using geothermal heat, and more particularly, a heat source required for cooling and heating can be stored and stored in a heat storage tank by using heat storage to be used for cooling and heating. The structure can be extremely simplified and the cost can be reduced by simplifying the auxiliary equipment such as three-way valve and diffuser, and the heat storage heat pump unit using geothermal heat can effectively utilize the heat quantity of the heat exchange water by selectively recycling the heat exchange water. It is about.;The heat storage heat pump unit using geothermal heat according to the present invention is a refrigeration cycle device connected to an underground heat exchanger and a first heat exchanger, and is installed to exchange heat with a second heat exchanger of the refrigeration cycle device and circulates heat exchange water connected between a heat storage tank and an air conditioner in the room. In the heat storage heat pump unit using geothermal heat consisting of a pipe, the heat exchange water circulation pipe is installed to exchange heat with the second exchanger, one side is connected to the heat storage tank and the heat exchange water is circulated in the forward and reverse direction by the first inverter pump 1 circulation tube; A second circulation pipe having both sides connected to the first circulation pipe, one side of which is connected to the air conditioner, and the heat exchange water circulated in the forward and reverse directions by a second inverter pump; First and second branch pipes respectively connected between the first circulation pipes; An on / off valve provided in the first branch pipe and selectively opened and closed; The three-way valve is installed at the branch point of the flow path of the second branch pipe, and the three-way valve to control the flow of the heat exchange water in one direction by the flow direction of the heat exchange water and the operation of the valve or to mix or distribute the heat exchange water in a predetermined ratio Characterized in that included.;Heat pump, geothermal heat, underground heat exchanger, refrigeration cycle, heat storage tank, heat exchange water
