HYBRID COOLING AND HEATING SYSTEM USING SOLAR AND GEOTHERMAL HEAT WITH A VARIABLE COOLING/HEATING STORAGE TANK PACKAGE

摘要

The present invention provides a cooling/heating variable heat storage tank package, by dividing the upper heat storage tank 10 and the lower heat storage tank 20 to be positioned vertically from each other, Inside the upper heat storage tank 10, a heat medium heat exchange coil pipe 12 and a hot water heat exchange coil pipe 13 are built in, but both ends of each of the coil pipes 12 and 13 cover the walls of the upper heat storage tank 10. The heat medium heat exchange coil pipe 12 can be connected to the heat medium circulation line SL, and the hot water heat exchange coil pipe 13 can be connected to the hot water (hot water) use line (UL-1) by passing through and exposing it to the outside. , The geothermal heat exchange coil pipe 22 is built inside the lower heat storage tank 20, but both ends of the geothermal heat exchange coil pipe 22 penetrate the wall of the lower heat storage tank 20 and are exposed to the outside. (HP), and a separate inlet pipe 24 and an outlet pipe 25 are formed on the wall of the lower heat storage tank 20 so that it can be connected to the cooling and heating line (UL-2), The upper heat storage tank 10 and the lower heat storage tank 20 are connected to each other by two connecting pipes 30a and 30b so that the fluid filled in the upper heat storage tank 10 and the lower heat storage tank 20 can move to each other. However, one of the connection pipes (30a) (30b) is configured with a pump (P1), and the fluid in the upper heat storage tank (10) is moved to the lower heat storage tank (20) by the drive of the pump (P), and the lower heat storage tank The fluid of (20) is pushed by pressure and moves to the upper heat storage tank (10) so that it can be circulated, and a valve is formed in each of the connecting pipes (30a) (30b), and if necessary, the upper heat storage tank (10) and the lower heat storage tank (10) The upper heat storage tank 10 in the summer season is used for hot water supply and the lower heat storage tank 20 is used for cooling, so that the flow of fluid between the tanks 20 can be intercepted so that they can be separated from each other. This is to be able to build a system that takes place at the same time.
