A turn-around inflow unit 118 is provided at the exhaust duct 114 so that when the temperature of the high temperature stored in the thermal storage reservoir 120 decreases with the passage of time, the low temperature is moved to the exhaust duct 114 connected to the place of use, and a temperature adjusting unit 119 for adjusting the temperature of the heat source to which the air inflowing from the outside is supplied is provided between the turn-around inflow unit 118 and the place of use. Here, the temperature adjusting unit 119 may be constituted by a cooling or heating device.
The heat pipe 115 is positioned inside the heat collecting pipe 113, and moves the solar heat collected at the heat collecting pipe 112 to the thermoelectric generation part 130 without heat loss, and both side ends of the heat pipe are connected to the thermoelectric generation part 130.
On the one hand, the heat pipe 115 includes an auxiliary heat pipe 1151 connected to the thermal storage reservoir 120 so that heat is supplied to the inside of the heat collecting pipe 112 with a small amount of insolation.
As described above, when the solar heat is collected by the solar heat collecting part 110 of the solar heat amplifying and heat collecting device 100, the heat collecting efficiency can be improved by forming the evacuated heat collecting tube 112 including the heat collecting element 1121 and heating the solar heat by the heat collecting element 1121.
Further, since the air conditioning unit 116 that adjusts the amount of wind supplied from the exhaust duct 221 by the temperature value measured by the heat source sensor 1122 is provided on one side of the exhaust duct 114, when the amount of solar radiation is small, the amount of wind supplied through the exhaust duct 221 is adjusted to supply wind, and therefore, there is an effect that solar heat collected by the heat collecting tube 112 is collected without being affected by the outside, and the collected solar heat can be used as thermal energy or electric energy.
The heat storage and storage unit 120 stores a part of the solar heat collected by the solar heat collection unit 110, stores the heat transferred through the exhaust duct 114, transfers the stored heat to the thermoelectric power generation unit 130 when the amount of solar radiation is small or at night, and transfers the heat from the thermoelectric power generation unit 130 to the power storage unit 230 of the wind turbine generator 200. At this time, the heat stored in the heat moved through the exhaust duct 114 stores only the heat of high temperature through the exhaust converting unit 117 provided in the exhaust duct 114. In addition, the stored high temperature is lowered in temperature with the passage of time, and when the temperature is lowered to be converted into a low temperature, the low temperature is moved and supplied to a place of use through the turn-around inflow device 118.
In a preferred embodiment of the present invention, the heat is stored in the heat storage portion 120 by using a gel.
The thermoelectric power generation portion 130 is configured to convert and store heat other than the heat that moves to the heat storage portion 120 among the solar heat collected by the solar heat collection portion 110 into electric energy, convert the heat received by the heat storage portion 120 into electric energy, and add the electric energy and the electric energy that converts the heat collected by the solar heat collection portion 110 into electric energy to move to the power storage portion 230 of the wind power generation apparatus 200.
The wind turbine generator 200 is a device for generating electric energy from wind, and includes a blade 210, a generator unit 220, and a power storage unit 230.
The blades 210 rotate with the wind, and may be formed in various forms such as a blower and a wind turbine.
The power generation part 220 is connected to the blade 210 and generates electricity by rotation of the blade 210, and includes: a plurality of gears 222 connected with the blades 210; a generator 223 connected to the plurality of gears 222 and generating electricity and moving the generated electricity to the electricity storage part 230; and an exhaust fan 221 connected to the generator 223 for supplying wind to an exhaust duct 114 provided on the solar heat collecting part 110 of the solar heat amplifying and collecting device 100. At this time, the exhaust fan 221 is supplied with electricity from the electricity storage unit 230 and supplies wind to the exhaust duct 114 of the solar heat collecting unit 110.
The power storage unit 230 is used for storing electricity, receiving and storing electricity generated by the power generation unit 220 and electricity of the thermoelectric power generation unit 130 of the solar heat amplification and heat collection device 100, and supplying the electricity to a place of use.
As described above, according to the integrated/combined solar power generating system using solar heat and wind power of the present invention, the solar heat and wind power are used to drive the solar heat amplifying and heat collecting device and the wind power generating device to be interlocked with each other to generate heat energy, electric energy or power, so that the utilization efficiency of natural energy such as solar heat and wind power is maximized, and energy or power can be efficiently generated even in a cloudy day, a night day with a small amount of sunshine or a weather without wind, and particularly, when the solar heat is collected by the solar heat collecting part of the solar heat amplifying and heat collecting device, the solar heat is heated by the heat collecting pipe formed in a vacuum state having the heat collecting element, so that the heat collecting efficiency is improved.
Further, although the conventional fusion/hybrid power generation system using solar heat and wind power has a large energy loss in the energy conversion process by converting natural energy such as solar heat and wind power into electric energy and then converting the electric energy into heat energy for use in heating of a building, the present invention has an effect of maximizing the utilization efficiency of natural energy such as solar heat by directly using a part of solar heat energy as heat energy for use in heating of a building and by generating power and converting the generated power into electric energy for use by using a part of solar heat energy.
In addition, since the air conditioning unit for adjusting the amount of wind supplied from the exhaust duct by the temperature value measured by the heat source sensor is provided at one side of the exhaust duct, when the amount of solar radiation is small, the amount of wind supplied through the exhaust duct is adjusted to supply wind, and thus, the solar heat collected by the heat collecting pipe is collected without being affected by the outside, and the collected solar heat can be used as thermal energy or electric energy.
The operation of the hybrid/solar power generation system 10 using solar heat and wind power according to the preferred embodiment of the present invention is explained as follows: the solar heat is tracked by the solar heat tracking unit 111 of the solar heat collecting part 110, and the solar heat is collected in the heat collecting pipe 112 through the reflecting plate 1111. The solar heat collected in the heat collecting tube 112 is rapidly heated by the thermoelectric element 1121 to improve the heat collecting efficiency. The heat collected by the heat collecting tubes 112, which is not sufficiently generated by the heat collecting elements 1121, is stored in the heat storage and storage unit 120 through the exhaust duct 114, and the heat collected by the heat collecting elements 1121, which is converted into electric energy by thermoelectric elements (peltier elements, not shown) in the thermoelectric power generation unit 130 through the heat pipe 115, is stored in the electric storage unit 230.
The heat stored in the heat storage unit 120 is stored in the heat storage unit 120, and the stored heat is supplied according to the use. At this time, the heat supplied to the use place is supplied at an appropriate temperature through the temperature adjusting unit 119, and the low temperature is supplied to the use place through the exhaust duct 114. The high temperature required for generating electric energy from the heat stored in the heat storage and storage unit 120 is transferred to the thermoelectric power generation unit 130, and the thermoelectric power generation unit 130 converts the first thermal energy transferred from the solar heat collector 110 through the heat pipe 115 and the thermal energy transferred from the heat storage and storage unit 120 into electric energy by the thermoelectric element, transfers the electric energy to the power storage unit 230 of the wind turbine generator 200, and stores the electric energy. On the other hand, the temperature of the high temperature stored in the heat storage reservoir 120 is decreased, and then the temperature is moved to the exhaust duct 114 by the turn-around inflow unit 118 and supplied to the use.
The solar heat amplifying and heat collecting apparatus 100 is used in a case where the solar radiation amount is large, and in a case where the solar radiation amount is small, the heat energy stored in the heat storage unit 120 is supplied to the heat collecting pipe 112 through the auxiliary heat pipe 1141, and the wind is supplied through the exhaust fan 221 of the wind power generating apparatus 200, so that the heat can be collected in the heat collecting pipe 112.
Unlike the driving of the solar heat amplifying and collecting device, the wind power generator 200 can generate electric energy in the presence of wind, generate electricity in the power generation unit 220 by the rotation of the blades 210, and move the generated electricity to the power storage unit 230. When the amount of solar radiation is small, the electricity stored in the electricity storage unit 230 is supplied to the exhaust fan 221 of the electricity generation unit 220, and the exhaust fan 221 is driven to supply wind to the heat collection pipe 112 through the exhaust pipe 114 of the solar heat collection unit 110 of the solar heat amplification and heat collection device 100, thereby collecting heat in the heat collection pipe 112.
