DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning system using a light / heat hybrid collector.

[0002]

2. Description of the Related Art Conventionally, a light / heat hybrid collector has been proposed which collects light energy of sunlight with a solar cell and collects heat energy of the sunlight with a solar heat collector. Have been. In the conventional light / heat hybrid collector, when collecting heat energy of sunlight, most of the heat collection method uses an aqueous heat medium to collect heat.

[0003] However, the method of collecting heat energy of sunlight using a water-based heat medium has a problem that it is difficult to perform exhaust heat treatment when heat collection is excessive. In other words, when heat collection becomes excessive, a large radiator is provided in the circulation path of the aqueous heat medium, and excess heat is released from this radiator or the hot water stored in the hot water storage tank is discarded, and new Must supply cold water to the hot water tank. By providing a radiator in the circulation path of the aqueous heat medium, the heat radiation efficiency is low, and the size of the device is increased. Furthermore, it is wasteful to throw away the hot water once stored in the hot water tank and supply fresh cold water.

[0004] In addition, since the conversion efficiency of a solar cell is extremely reduced when the temperature rises, it is desired that the light / heat hybrid collector be operated at a low temperature, considering only the solar cell. However, as described above, when thermal energy is collected using a water-based heat medium or the like, the operating temperature of the light / heat hybrid collector inevitably increases, and the conversion efficiency of the solar cell also decreases. .

Further, there is a structure in which a space is provided on the back surface side of a solar cell module provided with a plurality of solar cell elements to achieve a cooling effect by natural ventilation, but the solar cell cannot be actively cooled. In addition, the exhaust heat generated when cooling the solar cell cannot be used.

[0006]

SUMMARY OF THE INVENTION An air conditioning system using a light / heat hybrid collector according to the present invention has been made in view of the above-mentioned problems of the prior art. A solar cell element is arranged on the back side of the optical substrate, an air heating chamber is provided on the back side of the solar cell element, and the heating chamber and the living room of the house are connected by an inlet pipe and an outlet pipe. In an air conditioning system using a heat hybrid collector, an inlet port for selectively sucking outside air is provided on the inlet side pipe, and an upstream side and an outlet side pipe of the inlet side pipe are connected with a short circuit pipe, The short-circuit pipe is provided with an exhaust pipe for selectively discharging heated air from the inlet-side pipe or the outlet-side pipe to the outside air, and a blower is provided on the outlet-side pipe.

[0007]

According to the above configuration, it is possible to selectively prioritize the light energy and the heat energy of the sunlight, and to cool the solar cell and the solar cell according to weather conditions. The waste heat generated at the time can be appropriately used.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a diagram showing an embodiment of an air conditioning system using a light / heat hybrid collector according to the present invention, wherein 1 is a light / heat hybrid collector, 2 is a living room of a house, 3 is an inlet side pipe, and 4 is Outlet side piping.

The light / thermal hybrid collector 1 comprises:
As shown in FIG. 2, a plurality of solar cell elements 22 are provided on the back side of a light-transmitting substrate 21 made of glass, resin, or the like,
A heating chamber 24 is formed on the back side of the solar cell element 22 by being sandwiched between a silicon resin and an ethylene vinyl acetate resin 23 or the like. The plurality of solar cell elements 22 include:
They are electrically connected in series, parallel, or series-parallel so that desired power is obtained. The heating chamber 24 is provided with electric heating fins 24a and the like as necessary along the flow of air. With this configuration, the solar cell 22 collects the light energy of sunlight emitted from the translucent substrate 21 side, and heats and collects the air in the heating chamber 24 with the heat energy of the sunlight.

This light / heat hybrid collector 1
As shown in FIG. 1, the living room 2 of the house is connected to an inlet-side pipe 3 and an outlet-side pipe 4. That is, the air heated by the light / heat hybrid collector 1 basically circulates in the order of the light / heat hybrid collector 1, the outlet pipe 4, the living room 2, and the inlet pipe 3.

The inlet side pipe 3 is provided with an intake port 5 for sucking outside air. Further, an upstream side of the inlet port 5 of the inlet side pipe 3 and the outlet side pipe 4 are connected by a short pipe 6, and the short pipe 6 is provided with an exhaust port 7 for discharging air.

A first electric damper 8 is provided at the intake port 5, and a second electric damper 9 is provided upstream of the intake port 5 of the inlet pipe 3. A third electric damper 10 and a fourth electric damper 11 are provided on both sides of the exhaust port 7. Furthermore, the living room 2 in the outlet side pipe 4
A fifth electric damper 12 is provided at the entrance of the vehicle.
Furthermore, the outlet side pipe 4 is provided with a blower 13 for forcibly circulating the air in the system path.

Next, the operation of the light / heat hybrid collector according to the present invention will be described. Table 1 shows the open / closed states of the first to fifth electric dampers 8 to 12. In Table 1,
A mark indicates a state where the electric damper is opened, and a cross indicates a state where the electric damper is closed.

[Table 1]

In the case of A in Table 1, the first electric damper 8 and the third electric damper 10 are opened, and the second electric damper 9 and the fourth and fifth electric dampers 11 and 12 are closed. In this state, outside air is sucked from the intake port 5 and warm air is discharged from the exhaust port 7. This allows the solar cell 22 to be cooled by the outside air, thereby preventing a rise in temperature and a decrease in conversion efficiency. In the case of A, no warm air is sent to the living room 2. Therefore, it is effective in a warm period when heating is unnecessary.

In the case of B in Table 1, the first electric damper 8 and the fourth and fifth electric dampers 11, 12 are opened, and the second and third electric dampers 9, 10 are closed. In this state, outside air is sucked from the intake port 5, hot air is sent to the living room 2, and a part of the air in the living room 2 is discharged to the outside from the exhaust port 7. Thereby, while cooling the solar cell 22, the heating load of other heating appliances can be reduced, and the ventilation of the living room 2 can be performed without heat loss. Therefore, it is effective in a weak cooling period when weak heating is required.

In the case of C in Table 1, the second electric damper 9 and the fifth electric damper 12 are opened, and the first electric damper 8 and the third and fourth electric dampers 10 and 11 are closed. In this state, the air in the system circulates between the light / heat hybrid collector 1 and the living room 2, and the heat obtained by the light / heat hybrid collector 1 can partially cover the heating heat. Therefore, it is effective in severe winter when strong heating is required.

In the above embodiment, the light / heat hybrid collector 1 is connected to the living room 2 with the inlet side pipe 3 and the outlet side pipe 4, and the air heated by the light / heat hybrid collector 1 is directly blown into the room 2. However, as shown in FIG.
The inlet-side pipe 3 and the outlet-side pipe 4 connected to the light / heat hybrid collector 1 may be connected to a pipe of a duct type central air conditioning system. That is, FIG.
In (b), 2 is a living room, 31 is an indoor heat exchanger of a heat pump of a duct type central air conditioning system, 32
