Abstract:
1. A hybrid renewable energy system, comprising: a solar collector comprising a heat medium and configured to be provided on or in a vicinity of the building structure, the solar collector being configured for collecting solar heat to heat the heat medium that flows through a pipe conduit provided in the solar collector; a transfer pipe connected to the pipe conduit of the solar collector and configured for transferring the heat medium heated by the solar collector into an underground; a heat storage apparatus connected to the solar collector through the transfer pipe, installed underground, and configured for storing heat received from the heat medium therein and for heating, using the stored heat, both cold water supplied from the building structure through a supply pipe connected between the building structure and the heat storage apparatus and configured for introducing the cold water from the building structure to the heat storage apparatus and air supplied from an inlet duct connected between the building structure and the heat storage apparatus and configured for introducing the air from the building structure to the heat storage apparatus; a return pipe connected from the heat storage apparatus to the solar collector and configured for returning the heat medium from the heat storage apparatus to the solar collector; an inlet pipe connected from the heat storage apparatus to the building structure and configured for supplying hot water produced by the heat storage apparatus to the building structure; and a connection duct connected from the heat storage apparatus to the building structure and configured for collecting and supplying air heated by the heat storage apparatus into the building structure to heat a room of the building structure, wherein the heat storage apparatus comprises: a housing installed in an installation hole formed underground, the housing having a predetermined space therein; an underground heat storage configured such that inner and outer vicinity of the housing is filled with sand, and stones or pebbles are disposed in the housing; a heat exchanger installed in the underground heat storage in such a way that a bottom space is defined below the heat exchanger, wherein heat is stored in the underground heat storage by the heat medium that is transferred from the transfer pipe, and the heat medium which has passed through the heat exchanger is sent to the return pipe, the heat exchanger transferring the stored heat to cold water transferred form the supply pipe so that hot water is supplied into the building structure through the inlet pipe, the heat exchanger having a vent pipe along which cold air supplied from the inlet duct is moved upwards via the bottom space and is converted into hot air before being discharged to the connection duct; and a turbine generator generating electricity in such a way that a fan is operated by hot air that ascends through the connection duct obtained by heating up the cold air from outside, wherein the heat storage apparatus comprises a cover covering the heat exchanger, wherein the underground heat storage comprises a plurality of thermoelectric heaters disposed through the sand, the stone, or the pebbles in the underground heat storage and configured for applying heat to the stones or pebbles stored in the underground heat storage, the thermoelectric heaters being configured for being operated by electricity produced by a solar electric module installed in the building structure or in the vicinity of the building structure, wherein the heat medium comprises a silicone oil, wherein the heat exchanger comprises: a first heat exchanger configured such that the heat medium supplied from the transfer pipe transfers heat to the surrounding stones or pebbles to store the heat and is returned to the return pipe, the first heat exchanger being connected to the connection duct; a second heat exchanger provided around the first heat exchanger, the second heat exchanger transferring the stored heat from the stones or pebbles to cold water transferred from the supply pipe so that hot water is supplied into the inlet pipe, the second heat exchanger heating cold air, supplied from the inlet duct, while the cold air passes through the air vent pipes of the first heat exchanger via the bottom space before being supplied into the connection duct; and a support supporting the stones or pebbles provided in the first and second heat exchangers, so that the heat exchanger has three layered structure.
