| 摘要 |
The present invention relates to a cooling/heating and hot water supply system using a ground source heat pump for directly performing cooling with ground source heat, comprising a ground source heat exchanger installed in the ground to obtain and supply a heat source; a ground source heat pump producing hot water using the heat source of the ground source heat exchanger; a hot water supply storage tank storing hot water; a cooling load device and a heating load device as a load facility for directly performing cooling and heating; a heat source/cold water circulation pump providing power for circulating the heat source or cold water which has passed through the ground source heat exchanger in a system; a hot water heat storage pump pumping hot water from the hot water supply storage tank to the ground source heat pump; a heating circulation pump pumping room temperature water provided from the heating load device to the hot water supply storage tank; a cooing/heating and hot water supply switching valve switching over to cooling, heating, or how water supply; and a system controller controlling the foregoing components, wherein the system controller changes a flow channel of the ground source heat used as a heat source of the ground source heat pump for heating or hot water supply to supply cold energy accumulated in the ground to a load device for a cooling operation without actuating the ground source heat pump, thereby reducing energy for the cooling operation. |
