    Solar power generation / heat storage system
    BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar power generation / heat storage system. More specifically, the auxiliary heat storage function by solar energy is assumed in connection with a heat storage function by night power. The present invention relates to a photovoltaic power generation / heat storage system.
    As is well known, heating is installed in a home, a vinyl house farmhouse, a barn, etc., especially for indoor heating in winter, and such heating is generally operated by a commercial power source. Therefore, the cost for the commercial power consumed at the time of operation of the heating device is economically burdened.
    In consideration of such a situation, a late night electric power heat storage system has been proposed and applied to practical use in which the heating of the room can be performed by the electric power of the late night time to which the discount rate is applied. According to such a late-night electric power storage system, the heating of the room is performed by driving the heater by the power of the late-night time to heat the heating water stored in the heat storage tank and circulating the heated heating water through the heating system.
    In addition, the solar heat storage system that heats the heating water of the heat storage tank by solar heat to heat the room is also applied to the practical use, such solar heat storage system circulates the heating water heated by the solar heat through the heating system during the day to the room In this way, the economic burden is greatly reduced compared to the case of using a commercial power source.
    In addition, the latent heat storage system or the solar heat storage system considers not only indoor heating performed by heating the heating water of the heat storage tank by late night power or solar heat, but also a cooling operation that allows the refrigerant to be exchanged by using late night power or solar heat in summer.

    By the way, according to the above-described late night power heat storage system, the heating of the heat storage tank using the power of the late night time allows the heating of the room at a relatively low cost, but the heating water temperature of the heat storage tank heated in the late night time is time-lapsed. It is easy to be reduced to (經 時 的). Therefore, in order to compensate for the lowered temperature of the heating water, it is necessary to use commercial power that is charged at a normal rate before entering the late-night time zone, and thus it is difficult to expect the optimal heating effect by only the late-night electric power. .
    In the case of solar heat storage system, the solar heat is collected during the day to heat the heating water of the heat storage tank to an appropriate temperature to perform heating, but after the sunset time, the heating water by the solar heat becomes impossible, so the heating water at night In the case of poor temperature, especially when the weather is not good (e.g. during rainy weather or during snowy days), solar heat collection efficiency is lowered. It becomes difficult to be done.
    Accordingly, the present invention has been made in view of the above-described state of the art, and by interlinking the power generated from the late-night power and the solar power, good heat storage is possible at all times at low cost over the day and night, and the power generated from the solar power.

The control unit 42 receives the time data from the calendar timer 40 and generates a predetermined control signal to the power storage unit 44 so that the power stored in the battery 44 causes the power control unit 32 to operate. By heating the heater 34 by means of heat storage, heat storage is performed, and the control unit 42 receives corresponding time data from the calendar timer 40 in the late night time zone (for example, 22:00 to 08:00).

However, even if the light-transmissive substrate 2d is not designed according to the temperature condition of the solar cell 2c, there is no problem in the present invention.
    3 is a perspective view showing the structure of the heat storage tank employed in the photovoltaic power generation / heat storage system according to an embodiment of the present invention, the inlet 12 is formed in the upper predetermined portion of the heat storage tank (8) to introduce the heating water The water supply pipe 16 is formed at the lower end, so that the heating water is heated in the heat storage tank 8 so as to supply water for heating or hot water (or cold water for cooling).
    In addition, the interior of the heat storage tank 8 is surrounded by the inner shell 20 and the outer shell 26 to prevent heat exchange with the outside, the inner shell 20 is designed of glass wool (Glass Wool) and the like. The main inlet flows through the condenser 10 formed by connecting the heat collecting pipe 4 along the inner surface of the inner shell 20 and the main heater introduction pipe 22 formed at a lower predetermined portion of the heat storage tank 8. The heater 34 is deposited in the up / down direction of the endothelium 20 to prevent heat loss due to tropical flow of the heating water.
    In addition, an outer layer 26 of the heat storage tank 8 is formed at an outer side of the inner layer 20 in which an air layer is formed at a predetermined interval, and the outer shell 26 is made of polyethylene to insulate the inner shell 20. Or uretanol resins.
    In this case, the condensation unit 10 and the main heater 34 are installed inside the heat storage tank 8 so that the fruit heated by irradiation of solar heat is transferred from the condensation unit 10 via the heat collecting tube 4. The heating water is heated by causing heat exchange, and the heating water can be heated by applying to the main heater 34 using a commercial AC power or electric power generated by photoelectric conversion to sunlight.
    On the other hand, Figure 4 is a view showing a circuit configuration of the power conversion unit in the photovoltaic power generation / heat storage system according to an embodiment of the present invention, the power conversion unit 30 is a commercial AC power source 28 and the solar cell ( 2c) is a linked conversion means for performing power conversion, the AC / DC conversion unit 46 for converting the commercial AC power source 28, which is a midnight power to direct current and photoelectric conversion from the solar cell (2c) The DC / DC converter 47 converts the applied DC voltage into a constant voltage.
    In addition, the power conversion unit 30 is excited by the conduction of the transistors 48a and 48b and the conduction of the transistors 48a and 48b which are conducted according to whether the control signal is applied from the control unit 42 to perform a switching operation. The relay switches 50a and 50b to be performed and the relay switches 50a and 50b are switched on so that the applied current prevents reverse currents 52a and 52b.
    In addition, the voltage stored in the power storage unit 44 through the DC / DC conversion unit 47 is applied to the DC / AC conversion unit 54 to be AC-converted so that an auxiliary power source for operating various electric appliances in the summer. It is intended to be used as.
    Hereinafter, the operation of the photovoltaic power generation / heat storage system according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.
    First, if the operation of the device is largely divided by time zone, during the day when the sun is floating (for example, 08:00 to 16:00 o'clock), heat is accumulated by solar energy or heat generated by solar power. During the midnight hours from the sunset time (eg 16:00 to 22:00), the heat is generated by the power supplied from the sunlight and stored in the battery, and the midnight time zone (eg, 22:00 to 08). (00:00) is the heat storage by the late-night power.
    As described above, the heat storage operation using the heat source of sunlight directly during the day (for example, 08:00 to 16:00 hours) is carried out from the photovoltaic module 2 through the heat collecting tube 4 to produce a high temperature fruit. After performing heat exchange through the heat storage tank (8), it is repeated a series of cycles flowing into the solar module (2) again.
    In this case, the controller 42 receives the time data for the corresponding time from the calendar timer 40 and primarily performs the heat storage operation by directly using the heat source of solar light. The control signal is generated so that the relay switch 50a and the second relay switch 50b are switched off.
    Then, the electric force generated through the solar cell 2c of the solar module 2 is to be stored in the power storage unit 44 without heating the heater 34 configured in the heat storage tank (8).
    Here, the heat collecting amount can be largely divided into solar heat collection by irradiation of sunlight and queue heat collection by heat exchange between the queue around the fruit and the fruit in the heat collecting pin 2a, and the heat collecting pin 2a is In direct contact with the outside air, when the solar heat collecting amount increases, the temperature of the heat collecting fins 2a is relatively increased, which is higher than that of the surrounding queues.
    Therefore, the light-transmitting substrate 2d is deposited on the light-transmitting surface (upper surface) of the heat collecting plate 2b so that the queue in the photovoltaic module 2 is kept warm due to the light-transmissive substrate 2d. With this increase, the heat of the queue is maintained, so that the queue becomes hot compared to when the queue directly contacts the outside air, so that the queue heat collection amount is not reduced.
    On the other hand, in the heat storage state using the heat source of the solar heat directly, the fruit flowing into the heat collecting tube 4 of the photovoltaic module 2 is evaporated at a constant temperature to the middle of the passage to the ideal body of the gas phase and liquid phase, and then The temperature is gradually increased while being in a perfect vapor phase, and becomes a superheated steam, which flows up from the solar heat collecting tube 4 in the solar module 2 and flows out of the solar module 2.
    Then, the heat exchange is performed in the photovoltaic module 2 to convert the fruit into the superheated steam state is moved along the heat collecting pipe 4, is compressed and liquefied in the compressor 6, the condenser 10 in the heat storage tank (8) Heat exchange is performed.
    At this time, since the condenser 10 is attached in the longitudinal direction along the inner surface of the heat storage tank 8, it is possible to prevent the heating water stored in the heat storage tank 8 from heat loss due to a tropical flow phenomenon.
    In addition, the fruit heat-exchanged in the condenser 10 is expanded in volume by passing through the expansion valve 18 in a low-temperature liquid phase, causing a phase change in a low-temperature gas phase, and then flowing back into the solar module 2 to collect a series of heat collection cycles. This is done.
    On the other hand, while the heat storage operation is performed by directly using a heat source of sunlight during the day (for example, 08:00 to 16:00 hours), the controller 42 detects the water temperature sensing unit 36 or the outdoor temperature. When it is determined that the temperature signal applied from the unit 38 is lower than or equal to the set temperature, the controller 42 generates a control signal to the second relay switch 50b of the power converter 30 to generate the solar cell 2c. Power generated from) is supplied to the heater 36 to the heat storage.
    At this time, power is generated from the solar cell 2c deposited on the upper end of the heat collecting tube 4 attached to the inside of the solar module 2, and the solar cell 2c is connected to the upper end of the heat collecting tube 4. Since the heat exchange is carried out by the fruit of the low temperature flowing into the heat collecting tube 4 and installed in the solar cell, the solar cell 2c itself becomes a high temperature even when the solar radiation amount is increased, thereby preventing the photoelectric efficiency from decreasing.
    Such power generated in the solar cell 2c is adjusted to a constant voltage through the DC / DC converter 47 configured in the power converter 30 and applied to the power controller 32, wherein the controller 42 receives a corresponding temperature signal from the water temperature sensing unit 36 and the outdoor temperature sensing unit 38 and transmits a control signal to the power control unit 32 so that the heating water in the heat storage tank 8 is sufficiently heated. To generate heat.
    Meanwhile, between the sunset time and the late night time (for example, 16:00 to 22:00), the heat is generated by the power supplied and stored in the sunlight, which is late at sunset time from the calendar timer 40. When a time signal between time is applied, the controller 42 generates a stop signal to the compressor 6 to stop the operation of the heat storage device directly using the heat source of sunlight.
    At the same time, the controller 42 applies the ON signal only to the second relay switch 50b of the power conversion unit 30 to switch on to use the power stored in the power storage unit 44. The heater 34 is heated so that the heating water of the heat storage tank can be heated.
    In addition, in the late-night time zone (for example, from 22:00 to 08:00 hours), heat storage is performed by a commercial AC power source, which is a late-night electric power, and the time signal for the late-night time is transmitted from the calendar timer 40 to the controller 42. When applied, the controller 42 generates and conducts a control signal to the first transistor 48a so that the first relay switch 50a is switched on so that the commercial AC power source 28 is supplied to the power control unit 32. The main heater 34 is heated so that the main heater 34 can be heated.
    In addition, in the case of using the electric power generated by photoelectric conversion of the solar light as an auxiliary power source, when the heating is not necessary, such as summer, heat source obtained by heat exchange between the solar heat and the fruit in the heat collecting pin (2a) of the photovoltaic module (2) Hot water is supplied only through a path for directly accumulating heat, and the power obtained from the solar cell 2c is used as an auxiliary power source for various electric appliances.
    At this time, the control unit 42 turns off the first relay switch 50a to block the application of commercial power, and at the same time, the second relay switch 50b is turned on to use the heat storage tank using only solar heat. 8) heating water in the heating, and all the power generated through the solar cell (2c) is the power conversion in the DC / AC conversion unit 54 via the power storage unit 44 to the auxiliary power of various electric appliances It may be used as, or by using a power source stored in the power storage unit 44 by driving a fan on ice produced through an ice maker (not shown) it may be possible to enable indoor cooling.
    On the other hand, the present invention is not limited to the above examples, it is possible to variously change the structure of the photovoltaic module and the heat storage tank within the scope not departing from the gist, and the device (2a, 4, 6, 8, 10) can be designed so that the sunlight can be used as an auxiliary power source by photoelectric conversion.
    In addition, in the solar cell used in the present invention, in addition to the amorphous silicon solar cell, it is used in the relevant fields such as single crystal silicon solar cell, gallium-arsenic solar cell, germanium solar cell, cadmium-titanium solar cell, etc. It is possible to apply various solar cells.
    In the summer, the refrigerant may be replaced with a refrigerant instead of the fruit circulating in the heat collecting tube 4, so that the refrigerant may be circulated to allow for indoor cooling.
    As described above, according to the photovoltaic power generation / heat storage system according to the present invention through the heat collecting pins installed on both sides of the heat collecting tube, the fruit is irradiated with the heat generated from the solar cell together with the solar heat irradiated The efficiency of heat storage increases, and the solar cell absorbs the heat generated in the solar cell through the heat collecting tube at the bottom thereof, so that the solar cell itself is prevented from becoming a high temperature. The photoelectric conversion efficiency can be increased, and the thermal storage operation using the photovoltaic photovoltaic conversion and solar heat and commercial AC power are automatically adjusted for each time zone, thereby increasing the reliability of indoor cooling / heating by solar light. There is.
