Description

[Detailed Description of the Invention] [Technical Field] The present invention utilizes non-air conditioned areas such as stairwells and duct spaces, and uses one fan to conveniently air condition using solar heat collectors and Wi heat tanks. This invention relates to an air conditioner that utilizes solar heat.

[Background technology]

An example of a device that can air condition a house using a solar heat collector and a heat storage tank is as shown in Fig. It is known that the duct d is branched. However, in this case, one fan f1 flows the air downward in the duct C to store heat from the solar heat collector a to the heat storage tank.
In addition, in order to extract high-temperature air from the heat storage tank, it is necessary to provide another fan f2 for generating an air flow in the opposite direction, which increases the cost of the device.

[Purpose of the invention]

The purpose of the present invention is to provide an air conditioner that utilizes solar heat, which allows efficient air conditioning using a solar heat collector and an M heat tank using a single fan by utilizing a non-air conditioning section. There is.

[Disclosure of the invention]

An embodiment of the present invention will be described below based on the drawings.

In the figure, an air conditioner 1 that uses solar heat connects an air outlet 3 of a solar heat collector 2 and one ventilation port 5 of a heat storage tank 4 through a duct (Tl) leading to a ventilation port 8 of a room R. and the air population 9 of the solar heat collector 2, and the non-air conditioned part 1
It conducts to 0.

In addition, a fan F is connected to the air outlet 9 of the solar heat collector 2, and the other vent 6 of the heat storage tank 4 is connected to the non-air conditioned part 1.
0 and the discharge port side of the fan F are selectively connected to -V.

Sun F! ! ) The heat collecting plate D2 houses a heat collecting plate 12 inside a flat box 11 with heat insulation properties and has an open upper part, which is installed on the roof, and the upper part is shielded by a transparent plate 13, so that it absorbs solar heat. The air is heated by the heat collecting plate 12 that collects heat.

Further, one end of the duct TI is connected to the air outlet 3 located above the solar heating device 2.

The duct) TI extends into the underfloor space, and the other end is connected to one of the ventilation ports 5 as described above.

Note that the duct TI communicates with a vent 8 provided in the room R.

The heat storage tank 4 has a small gap at the front and back in a container part partitioned off by a heat insulating material in the underfloor space below the room R, and has crushed stone,
A heat storage material 15 such as gravel is loaded.

The non-air conditioned section To is a space that communicates with the upper and lower sides and does not particularly require air conditioning, such as an atrium, a staircase, or a duct space, and is configured as a staircase in this embodiment. Further, the non-air conditioned section 1o faces the room R, and the room R is provided with an exhaust port 17 leading to the non-air conditioned section 1o.

A duct T2 extending from the air population 9 of the solar heat collector 2 and feeding air to the air population 9 through a fan F is connected to the ceiling of the non-air conditioned part 10.

Further, to the duct T2, a duct T3 which communicates with the other vent 6 of the heat storage tank 4 is connected at the connection point on the outlet side of the fan F, and to the duct T3, the connection point B is connected to the duct T3. A duct 1-T4 that communicates with the underfloor of the air conditioning unit 1o is branched and formed.

Note that the duct l-74 can also be directly connected to the heat storage tank 4.

The duct T1 is provided with a damper D1 on the upstream side of the vent 8, and the vent 8 is also provided with a damper D2 (t TJ
It will be done. Furthermore, a damper D3 is interposed between the duct) T2 and the air population 9 of the connection point A, and the duct) T3, T4
are provided with dampers D4 and D5, respectively.

However, when the sun shines during the winter season, by opening only the dampers DI D2 and D3 and driving the fan F, the warm air from the solar heat collector 2 flows through the air outlet 3, It flows into the room R through the duct TI and the vent 8 and flows into the non-cavity part 10 through the exhaust port 17, and can be returned to the air population 9 of the solar heat collector 2 through the duct T2.

Furthermore, when storing heat in the heat storage tank, the dampers D1, D3, and D5 are opened as shown in FIG. After exchanging heat with the heat storage material 15, the air flows through the duct T3 to the connection point B, passes through the duct r4, and flows into the non-air conditioned section 10. Also, this circulating air passes through the duct) T2 to the solar heat collector 2.
Return to

Furthermore, in order to take out the heat stored in the heat storage tank 4, as shown in FIG. from the other vent 6 to the heat storage tank 4.
Since the flow of air is different from that during heat storage, high-temperature air can be taken out. Further, the warm air passes through one of the ventilation ports 5, passes through the duct T1, and flows into the room R from the ventilation port 8.

Note that the air can be circulated through the exhaust port 17.

Furthermore, when the amount of solar radiation is large, when direct heating with hot air and heat storage in the heat storage tank 4 are performed at the same time, as shown in FIG. 2(d), by opening the dampers D1, D2, D3, and D5, The air passing through the duct T1 is
and one ventilation port 5 at the same time.

〔Effect of the invention〕

In this way, the air conditioner that utilizes solar heat according to the present invention can perform direct heating using hot air in the solar heat collector, heat storage in the heat storage tank, efficient extraction of heat storage through backflow, and storage of heat in the heat storage tank at the same time as the room space. All of these can be done using a single fan, which increases the utilization efficiency of the device and improves the air conditioning efficiency.It also makes it possible to share ducts, dampers, etc., thereby increasing the utilization efficiency of the device. In addition, since a fan is installed at the air inlet of the solar heat collector, the inside of the solar heat collector becomes high pressure, preventing cold air from flowing in even if an air hole occurs, and preventing the inflow of cold air even if the outside air is contaminated. There is no inflow of the air, and the spatial effect and livability of the room are enhanced. Furthermore, since low-temperature air after air conditioning flows through the fan, it can have many effects such as increasing its durability and reducing heat loss.
