In the conventional hybrid solar energy utilization system as described above, heat is collected in one heat storage tank with the same heat exchange capacity regardless of the season. However, in summer, the solar radiation is high, the outside temperature is high, and the city water temperature is high, so if the system is assembled according to other seasons, the temperature inside the heat storage tank will become extremely high, and not only will the waste heat be stored, but it will pass through it. Since the liquid heat medium returning to the hybrid panel also has a high temperature, there is a risk that the power generation efficiency of the power generation cell may be extremely reduced or the power generation cell itself may be damaged. On the other hand, in winter, the opposite is true: the solar radiation is low, the outside temperature is low, and the city water temperature is low, so if the system is set up in another season, the temperature in the heat storage tank will be very low, and in some cases hot water can be supplied. There was a problem that the temperature could not be obtained.

The present invention has been made in order to solve the above-mentioned problems, and does not significantly lower the power generation efficiency of the power generation cell and damages the power generation cell itself when the amount of heat collected is large, such as during summer. (EN) A hybrid solar energy utilization device capable of maintaining a temperature without danger and maintaining a certain temperature in a heat storage tank when the amount of collected heat is small such as in winter.

[0007]

In the hybrid solar energy utilizing apparatus according to the present invention, a solar power generation module and a solar heat collection module are integrated, and the solar power generation module distributes liquid heat flowing in the solar heat collection module. In what is configured to be affected by the heat of the medium, a pipe that circulates and circulates the liquid heat medium collected by the solar heat collecting module, and a plurality of heat storage tanks provided in parallel in the middle of the pipe are provided. When the heat collection amount is small, it is detected and the liquid heat medium is circulated and circulated in one heat storage tank, while when the heat collection amount is large, it is detected and the liquid heat medium is stored in a plurality of heat storage tanks. It has been circulated in circulation.

Further, the apparatus is provided with a tank temperature detecting means for detecting the temperature in the heat storage tank, and first, the liquid heat medium is circulated and circulated in one heat storage tank, and then the temperature in the one heat storage tank becomes equal to or higher than a set temperature. When such a state is detected, the liquid heat medium is switched to be circulated and circulated to another heat storage tank, and this operation is repeated until a predetermined number of heat storage tanks is reached.

Further, an external temperature detecting means for detecting the external temperature is provided, and the liquid heat medium is circulated and circulated through an arbitrary number of heat storage tanks which are set to match the preset temperature by detecting the external temperature. It has been switched.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1. FIG. 1 shows a hybrid solar energy utilizing apparatus according to a first embodiment of the present invention. The most basic example is a case where two heat storage tanks are provided in parallel. The number may be three or more in parallel.

Reference numeral 1 denotes a photovoltaic power generation module comprising a device having a photovoltaic effect using single crystal Si, amorphous, or the like, and 2 denotes a solar heat collecting module.
The integrated structure is similar to the conventional hybrid panel 21 shown in FIG. Reference numerals 3a to 3e denote pipes through which antifreeze as a liquid heat medium flows, 4a and 4b denote heat storage tanks using water as a heat storage material, 5a and 5b denote heat exchangers, and 6a and 6b denote three-way valves. Reference numeral 7 denotes a temperature sensor in the heat storage tank, and 8 denotes a judging device for a signal from a sensor such as a microcomputer. Note that 11 is an inverter, and 12 is a commercial power supply.

Next, the operation of the first embodiment will be described. The solar power generation module 1 and the solar heat collection module 2 are in contact with each other without any gap. Here, solar energy is received, power is generated by the solar power generation module 1, and the solar heat collection module 2
Heat is collected by the liquid heat medium flowing inside. This liquid heat medium flows from the pipe 3a to the heat storage tank 4a through the pipe 3b by the operation of the three-way valves 6a and 6b. The liquid heat medium raises the water temperature in the heat storage tank 4a by passing through the heat exchanger 5a. Thereafter, the liquid heat medium returns from the pipe 3c to the solar heat collecting module 2 through the pipe 3a. By repeating this circulation, the temperature of the water in the heat storage tank 4a is increased.

Here, the temperature inside the tank detected by the temperature sensor 7 incorporated in the heat storage tank 4a is previously determined by a judging device 8 such as a microcomputer.
When the temperature limit is reached, the three-way valve 6a,
The operation of 6b is switched, and the liquid heat medium flows from the pipe 3a to the heat storage tank 4b through the pipe 3d. Then, the water temperature in the heat storage tank 4b is raised by passing through the heat exchanger 5b.
After that, the liquid heat medium returns from the pipe 3e to the solar heat collecting module 2 through the pipe 3a. By repeating this circulation, the temperature of the water in the heat storage tank 4b is increased. When the water temperature in the heat storage tank 4a falls below the limit temperature due to the passage of time, the three-way valves 6a and 6b operate again to return to the original state and raise the water temperature in the heat storage tank 4a.

Accordingly, when the amount of heat collection is large, such as in the summer, the temperature in the heat storage tank is maintained at a preset limit temperature without lowering the power generation efficiency of the power generation cell and there is no danger of damaging the power generation cell itself, and in the winter. When the amount of collected heat is small, the temperature in the heat storage tank can be maintained to some extent. That is, in the summer, by using a plurality of heat storage tanks at an appropriate temperature in sequence, obstacles to the power generation cells are eliminated, and in the winter, one heat storage tank is used to reduce the required minimum temperature. It's something to keep.

Embodiment 2 FIG. Second Embodiment FIG. 2 is a circuit diagram of a hybrid solar energy utilizing apparatus according to a second embodiment of the present invention. In the figure, 1 to 5, 8, 11, and 12 have the same configuration as that of the first embodiment shown in FIG. 6c, 6d
Is an electromagnetic valve provided in each of the pipes 3d and 3e, and 9 is an ambient temperature sensor. The number of heat storage tanks may be three or more in parallel, and the capacity of the heat storage tank 4a may be the largest, and the capacity of the heat storage tank 4b and the next heat storage tank may be reduced.

Next, the operation of the second embodiment will be described. Basically, the operation is almost the same as the operation described in the first embodiment. When the external temperature detected by the external temperature sensor 9 provided on the roof or the like is equal to or higher than the temperature set in advance by the determiner 8 such as a microcomputer. In some cases, the solenoid valves 6c, 6d are opened, and the liquid heat medium passes through the pipes 3a, 3b, 3d and the two heat storage tanks 4a, 4
It flows to b. Among them, the liquid heat medium passes through the heat exchangers 5a and 5b in the respective heat storage tanks, thereby forming the heat storage tanks 4a and 4b.

It returns to the solar heat collection module 2 through c, 3e, and 3a. By repeating this circulation, the temperature of the water in the heat storage tanks 4a and 4b is raised.

When the outside temperature detected by the outside temperature sensor 9 is lower than the temperature set in advance by the judging device 8 such as a microcomputer, the solenoid valves 6c and 6d are closed, and the liquid heat medium is supplied to the pipes 3a and 3b. And flows only to the heat storage tank 4a.
The water temperature in the heat storage tank 4a is increased by passing through the heat exchanger 5a in the heat storage tank 4a. After that, the liquid heat medium returns to the solar heat collecting module 2 through the pipes 3c and 3a. By repeating this circulation, the temperature of the water in the heat storage tank 4a is raised.

The solenoid valves 6c and 6d are connected to the pipes 3d and 3e.
However, if provided in the pipes 3b and 3c, the temperature of the water in the heat storage tank 4b can be increased.

When three or more heat storage tanks are connected in parallel, a plurality of set temperatures of the determiner 8 which operates by detecting the ambient temperature are prepared so that the ambient temperature reaches each set temperature, or When the temperature is lower than the lower limit, the small-capacity heat storage tank 4b and the electromagnetic valve of the next-stage heat storage tank may be controlled to be sequentially opened and closed.

Therefore, when the amount of heat collection is large such as in summer, the temperature in the heat storage tank is maintained at a temperature at which there is no danger of damaging the power generation cell itself without lowering the power generation efficiency of the power generation cell, and when the amount of heat collection is small such as in winter. Can maintain a certain temperature in the heat storage tank. In other words, in summer, a plurality of heat storage tanks are sequentially used at an appropriate temperature to eliminate the obstacle to the power generation cell, and in winter, one heat storage tank is used to reduce the required minimum temperature. We are trying to keep it.

Embodiment 3. FIG. 3 is a circuit diagram of a hybrid solar energy utilization device according to a third embodiment of the present invention. In the figure, 1 to 5, 8, and 12 have the same configuration as the first embodiment shown in FIG. Reference numerals 6c and 6d are electromagnetic valves provided in the pipes 3d and 3e, respectively, and 10 is a solar radiation amount sensor. The number of heat storage tanks may be three or more in parallel, the capacity of the heat storage tank 4a is the largest, and the capacity of the heat storage tank 4b and the heat storage tank subsequent thereto may be small.

Next, the operation of the third embodiment will be described. Basically, the operation is the same as that described in the first embodiment,
When the solar radiation detected by the solar radiation sensor 10 provided on the roof or the like is equal to or greater than the solar radiation previously set by the determiner 8 such as a microcomputer, the solenoid valves 6c and 6d are opened, and the liquid heat medium is supplied to the pipe 3a, It flows to two heat storage tanks 4a and 4b through 3b and 3d. Among them, the liquid heat medium passes through the heat exchangers 5a and 5b in the respective heat storage tanks to raise the water temperature in the heat storage tanks 4a and 4b. After that, the liquid heat medium is pipes 3c, 3
e, return to the solar heat collecting module 2 through 3a. By repeating this circulation, the temperature of the water in the heat storage tanks 4a and 4b is raised.

When the solar radiation detected by the solar radiation sensor 10 is smaller than the solar radiation set in advance by the determiner 8 such as a microcomputer, the solenoid valves 6c and 6d are closed, and the liquid heat medium is supplied to the pipe 3a. It flows only to the heat storage tank 4a through 3b.
The water temperature in the heat storage tank 4a is increased by passing through the heat exchanger 5a in the heat storage tank 4a. Thereafter, the liquid heat medium returns to the solar heat collecting module 2 through the pipes 3c and 3a. By repeating this circulation, the temperature of the water in the heat storage tank 4a is raised.

The solenoid valves 6c and 6d are connected to pipes 3d and 3e.
Instead, if the pipes 3b and 3c are provided, the temperature of the water in the heat storage tank 4b can be raised.

In the case where three or more heat storage tanks are arranged in parallel, a plurality of set insolation amounts of the determiner 8 which operate by detecting the amount of insolation are prepared, and the amount of insolation reaches each set amount of insolation. Alternatively, when the temperature falls below the threshold, the small-capacity heat storage tank 4b and the electromagnetic valve of the next-stage heat storage tank may be sequentially controlled to be opened and closed.

Therefore, when the amount of heat collection is large such as in summer, the temperature in the heat storage tank is maintained at a temperature at which there is no danger of damaging the power generation cell itself without lowering the power generation efficiency of the power generation cell, and when the amount of heat collection is small such as in winter. The temperature inside the heat storage tank can be maintained to some extent. In other words, in summer, a plurality of heat storage tanks are sequentially used at an appropriate temperature, thereby eliminating an obstacle to a power generation cell. In winter, one heat storage tank is used to maintain a required minimum temperature. Is what you are trying to do.

Embodiment 4 FIG. 4 is a circuit diagram of a hybrid solar energy utilization device according to a fourth embodiment of the present invention. In the figure, 1 to 5, 8, 11, and 12 have the same configuration as that of the first embodiment shown in FIG. 6c, 6d
Is an electromagnetic valve provided in each of the pipes 3d and 3e, 9 is an external temperature sensor, and 10 is a solar radiation sensor. The number of heat storage tanks may be three or more in parallel, the capacity of the heat storage tank 4a is the largest, and the capacity of the heat storage tank 4b and the heat storage tank subsequent thereto may be small.

Next, the operation of the fourth embodiment will be described. Basically, the operation is almost the same as that described in the first embodiment, and the external temperature and the amount of solar radiation detected by the external temperature sensor 9 and the solar radiation sensor 10 provided on the roof or the like are previously determined by the determiner 8 such as a microcomputer. When the temperature is equal to or higher than the set ambient temperature and solar radiation, the solenoid valves 6c and 6d are opened, and the liquid heat medium passes through the pipes 3a, 3b and 3d and passes through the two heat storage tanks 4a and 4d.
It flows to b. The liquid heat medium therein passes through the heat exchangers 5a and 5b in the respective heat storage tanks, whereby the heat storage tanks 4a and 4b
Increase the water temperature in b. After that, the liquid heat medium is pipe 3
Return to the solar heat collecting module 2 through c, 3e and 3a. By repeating this circulation, the temperature of the water in the heat storage tanks 4a and 4b is raised.

Further, when the ambient temperature and the amount of solar radiation detected by the ambient temperature sensor 9 and the solar radiation amount sensor 10 are less than the ambient temperature and the amount of solar radiation set in advance by the determination device 8 such as a microcomputer, the solenoid valve 6c, 6d is closed, and the liquid heat medium flows only to the heat storage tank 4a through the pipes 3a and 3b.
The water temperature in the heat storage tank 4a is raised by passing through the heat exchanger 5a in the heat storage tank 4a. After that, the liquid medium returns to the solar heat collecting module 2 through the pipes 3c and 3a. By repeating this circulation, the temperature of the water in the heat storage tank 4a is increased.

The ambient temperature sensor 9 and the solar radiation sensor 1
A value of 0 causes the determiner 8 to operate based on either one of the detection results, thereby improving the responsiveness.

When three or more heat storage tanks are connected in parallel, a plurality of set temperatures and set solar radiation amounts of the determining device 8 which operates by detecting the ambient temperature and the solar radiation amount are prepared respectively. When the amount reaches or falls below each set temperature and each set solar radiation amount, the electromagnetic valves of the small-capacity heat storage tank 4b and the next-stage heat storage tank may be sequentially controlled to be opened and closed.

Therefore, when there is a large amount of heat collection, such as during the summer, the temperature inside the heat storage tank is maintained at a temperature that does not lower the power generation efficiency of the power generation cell and does not damage the power generation cell itself, and when the amount of heat collection is small such as during the winter. Can maintain a certain temperature in the heat storage tank. In other words, in summer, a plurality of heat storage tanks are sequentially used at an appropriate temperature, thereby eliminating an obstacle to a power generation cell. In winter, one heat storage tank is used to maintain a required minimum temperature. Is what you are trying to do.

This will be described in more detail with reference to the relationship diagrams between the heat collection time and the heat collection temperature shown in FIGS. 5 and 6 show that the HB module area 6
[M ² ], a fluid heat medium flow rate of 1 [liter / min] is installed at a standard roof slope angle (22 degrees) toward the south, and each heat storage tank holds 150 liters of water. When two tanks capable of storing heat are installed as heat storage materials, FIG. 5 shows the case where heat is collected on a fine summer day in Tokyo, and FIG. 6 shows the case where heat is collected on a fine winter day in Tokyo. In both figures, the solid line shows the case where heat is collected by only one heat storage tank, and the broken line shows the case where heat is collected by two heat storage tanks. In addition, what was shown by the dotted line is the limit temperature of the heat storage tank temperature in each season.
As can be seen from the figure, the temperature in one heat storage tank is 9 in summer.
Since the temperature becomes about 0 ° C. and the temperature of the liquid heat medium flowing through the medium also becomes high, there is a concern that the power generation efficiency of the power generation cell may be reduced or accelerated. In winter, when the number of heat storage tanks becomes two, the heat storage temperature does not easily rise, and the temperature rise stops at a point where a temperature at which hot water can be supplied can be obtained.
However, this has two heat storage tanks in the summer and one heat storage tank in the winter.
It is understood that both systems reach a temperature at which hot water can be supplied, and the power generation does not cause an extreme decrease.

The present invention does not limit the components of the power generation / heat collecting module, the method of distributing the liquid heat medium, the type of the liquid heat medium, the size and heat insulation performance of the heat storage tank, the installation position, and the like. .
