供することにある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner that simultaneously supplies and discharges outdoor air and indoor air. Using a sensible heat exchanger such as a plate type or plate fin type, the flow direction of supply and exhaust air is periodically reversed in both directions to cycle the primary and secondary airflows that pass through one air passage in the heat exchanger. The object of the present invention is to provide a more convenient air conditioner that has a more efficient sensible heat exchange capability and is maintenance-free by exchanging sensible heat with each other and performing sensible heat exchange ventilation.

ある。 Plate-type sensible heat exchangers are conventionally used in air conditioning ventilation fans. The partition plates of this heat exchanger are made of thermally conductive material such as metal or plastic, and supply air flow and exhaust air flow are alternately and constant between each layer partitioned by the partition plate. This method exchanges sensible heat through a partition plate by passing in the same direction, and the sensible heat exchange efficiency is generally around 65%. In addition, since the direction of airflow flowing through each layer between the partition plates does not change, dust tends to accumulate at the air inlet of the heat exchanger.
Not only is a filter required, but cleaning the heat exchanger inlet is a regular maintenance item.

定期的なメインテナンスも不要になる。 The present invention solves the above-mentioned drawbacks of conventional air conditioners that use a sensible heat exchanger and perform sensible heat exchange ventilation by flowing supply air and exhaust air in a fixed direction between each partition plate in the heat exchanger. It is something. In this method, sensible heat exchange is performed not only by heat conduction through the partition plates, but also by the heat storage and heat dissipation effects of the elements (partition plates and spacing plates), so the heat exchange efficiency is lower than that of the conventional method. It is possible to make it considerably higher than that of In addition, the direction of the flow of air in each layer between the partition plates of the heat exchanger is periodically reversed when both airflows are exchanged, so dust does not adhere to and accumulate at the inlet of the heat exchanger, eliminating the need for a filter. In addition, regular maintenance such as removing dust from the inlet of the heat exchanger becomes unnecessary.

FIG. 1 is a schematic external view of a sensible heat exchanger according to an embodiment. In the figure, 1 is a partition plate, and 2 is a spacing plate, both of which are molded aluminum plates. FIG. 2 is a partially enlarged cross-sectional view of this heat exchanger. In this figure, a partition plate 1 and a spacing plate 2 have thermal conductivity and heat storage properties. In FIG. 2, when supply air is flowing from the outdoor side to the indoor side in the flow path between the partition plates, exhaust air is flowing from the indoor side to the outdoor side in the flow path on the outside. In this case, if the indoor and outdoor atmospheres are set to 26°C and 33°C, respectively, the sensible heat from the outdoor side is stored in the partition plate 1 and the spacing plate 2 facing the inside of the flow path A, and some of the heat is are partition plate 1 and spacing plate 2
The heat is transferred to the outside through the contact portion 3 and the partition plate 1 by heat conduction, and is discharged to the outside. Here, if the primary airflow and secondary airflow flowing between each layer are exchanged with each other after a certain period of time, flow path A will have exhaust air from the indoor side to the outdoor side, and flow path B will have air being supplied from the outdoor side to the indoor side. Therefore, the sensible heat previously accumulated in the partition plate 1 and the spacing plate 2 facing the inside of the flow path A is discharged to the outside along with the exhaust flow from the indoor side to the outdoor side.

きることにある。 The advantage of this method is that the two types of airflow flowing between each layer sandwiched between each partition plate are periodically exchanged, and
By reversing the direction, the sensible heat brought into the heat exchanger from the outdoor side is discharged outside by heat conduction through the partition plates, and the heat accumulated on the partition plates and spacing plates is discharged outside again. As a result, heat recovery efficiency can be dramatically improved compared to conventional air conditioning ventilation fans that use sensible heat exchangers.

率を向上させることが可能である。 FIG. 3 is a schematic diagram showing a method for measuring heat exchange efficiency using this method, and FIG. 4 shows the measurement results.
4 in the figure is a heat exchanger, the size is 150□mm x 250mm,
5 and 5' are propeller fans, which allow the forward and reverse rotation directions to be changed. The air volume passing through the heat exchanger is set to 2.5 m 3 /min in both forward and reverse directions. Measurement results have confirmed that when the direction of rotation of the fan is reversed, it reaches a steady value of 2,600 revolutions per minute ten seconds after turning on the direction switch. A, B,
Temperature sensors were set at positions C and D, and the temperature changes were recorded on the recorder while the direction of the wind flow was periodically reversed. Using such a test device, the indoor and outdoor temperature conditions are
When the air flow direction is periodically reversed in a 30-second cycle by setting between two adjacent constant-temperature rooms that are automatically adjusted to 26°C and 33°C, one of the heat exchangers 4 The supply air flow from the outdoor side and the exhaust air flow from the indoor side, which pass through the two air passages, replace each other. The result of determining the change in sensible heat exchange efficiency in this case is indicated by X in FIG. Y in FIG. 4 is the average value for 30 seconds. Note that the horizontal axis of the graph is the elapsed time from the time of switching the wind direction. In the diagram,
Straight line Z uses the same heat exchanger, continues to flow in a fixed direction without reversing the flow direction, and connects the supply air flow from the outdoor side through one air path in the heat exchanger 4 to the indoor air flow. For comparison, the measurement results of the heat exchange efficiency at equilibrium obtained in the case of a so-called conventional type heat exchange system in which exhaust gas flows from the inside are not exchanged with each other are shown. As is clear from these measurement results, by periodically reversing the direction of the air passing through the heat exchanger and replacing the supply air flow and exhaust air flow passing through one air path, heat exchange efficiency is improved compared to the conventional method. It is possible to do so.

The rotation directions of a and 7b are always constant, and the reversal of the direction of the air flow passing through the heat exchanger and the mutual exchange of the supply air flow and the exhaust air flow are performed by the link mechanism 12 in the heat exchanger 1.
3 is performed by periodically swinging 90 degrees. With the center 17 of the heat exchanger 13 as the rotation axis,
Repeat the swing once every 30 seconds as shown by arrow 14. The time required for swinging is about 1 second.

期的に行なわれればよい。 In the above embodiment, the exchange of both airflows passing through the heat exchanger is performed by swinging the heat exchanger, but it is also possible to exchange both airflows by switching the damper or by reversing the direction of rotation of the fan. In short, it is sufficient that the flow of air passing through one air passage of the heat exchanger is periodically reversed, and the exchange of both air flows is performed periodically.
