Abstract

PURPOSE:To improve the sensible heat exchange capacity and the security of the titled air conditioner by a method wherein in the air conditioner using a plate type or a plate fin type sensible exchanger, the sensible heat exchanger is rotated in the clockwise and counter clockwise directions periodically so as to reverse the flow directions of primary and secondary airs. CONSTITUTION:The plate type sensible heat exchanger is constituted such that partition plate 1 made of aluminum and corrugated spacer plates 2 are laid one above another in an alternative fashion with the direction of corrugation of one pacer plate 2 running normal to that the another. Such heat exchanger 3 is housed rotatably in the front portion of an air conditioning ventilating fan casing provided with inlet and outlet passages and is rotated through a link mechanism 12 in the clockwise and counter clockwise direction every predetermined period of time, i.e., every 30sec. Consequently, the sensible heat introduced into the heat exchanger 13 from outside the room is discharged outside the room again through the partition plates 11 by the action of heat transfer and the heat accumulated by the partition plates 1 and the spacer plates 2 is discharged outside the room again.

By periodically reversing the flow direction of intake and exhaust air in both directions using a sensible heat exchanger such as the plate fin type or plate fin type, the ventilation system has a more efficient sensible heat exchange capacity. Our goal is to provide more convenient air conditioners with features such as maintenance-free operation.

インテナンス項目として必要である。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 the intake air flow and exhaust air flow alternately in a fixed direction between each layer separated by the partition plate. This method performs sensible heat exchange through a partition plate, and the sensible heat exchange efficiency is generally about 65 cm. In addition, since the direction of the airflow flowing through each layer between the partition plates does not change, it is easy for dust to adhere and accumulate at the air inlet of the heat exchanger, which not only requires a filter but also cleaning of the inlet of the heat exchanger. is required as a regular maintenance item.

という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 intake and exhaust air in a fixed direction between each partition plate in the heat exchanger. It is. 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 radiation 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 However, since the direction of the flow of air in each layer between the partition plates of the heat exchanger is also periodically reversed, dust does not accumulate at the inlet of the heat exchanger, which not only eliminates the need for a filter, but also eliminates the need for a filter. Periodic maintenance such as removing dust from the heat exchanger inlet is no longer necessary.

以下にその実施例を図にもとすいて説明する。The embodiment will be explained below with reference to the drawings.

第１図は実施例の顕熱交換器の模式外観図である。FIG. 1 is a schematic external view of a sensible heat exchanger according to an embodiment.

６℃。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, the partition plate 1 and the spacing plate 2 have thermal conductivity and heat storage properties. In FIG. 2, when intake air is flowing from the outdoor side to the indoor side in the flow path A between the partition plates, exhaust air is flowing from the indoor side to the outdoor side at the flow path opening. In this case, the indoor and outdoor atmospheres are each

。When the temperature is set at 33°C, sensible heat from the outdoor side is stored in the partition plate 1 and the spacing plate 2 facing inside the channel layer, and a part of the heat is transferred to the contact area 3 between the partition plate 1 and the spacing plate 2. It is transferred to the mouth side by heat conduction through the partition plate 1 and is discharged to the outside. Here, if the direction of the airflow flowing between each layer is reversed after a certain period of time, exhaust air from the indoor side to the outdoor side will flow through the flow path A, and intake air from the outdoor side to the indoor side will flow through the flow path opening. Sensible heat accumulated in the partition plate 1 and the spacer plate 2 facing inside the layer is discharged outdoors along with the exhaust flow from the indoor side to the outdoor side.

べて、熱回収効率を飛躍的に向上できることにある。The advantage of this method is that by periodically exchanging and reversing the airflow flowing between each layer sandwiched between each partition plate, the sensible heat that is brought into the heat exchanger from the outdoor side is returned to the heat exchanger through the partition plate. By discharging the heat outside by conduction, and discharging the heat stored in the partition plates and spacing plates back to the outside, the heat recovery efficiency is improved compared to the conventional air conditioning ventilation fan using a sensible heat exchanger. It is possible to improve dramatically.

ある。Set temperature sensors at positions B, C, and D, and record the temperature changes on the recorder while periodically reversing the direction of the wind flow. The temperature conditions for the indoor and outdoor sides of this test equipment were 26°C and 33°C, respectively.
The fourth study is the result of determining the change in sensible heat exchange efficiency when the direction of airflow is periodically reversed in a 30-second cycle, set between two adjacent constant-temperature rooms that are automatically adjusted to ℃. This is the X in the diagram. 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 figure, the straight line Z represents the equilibrium obtained in the so-called conventional type of total heat exchange system, in which the same heat exchanger is used and the air continues to flow in a fixed direction without reversing its direction. For comparison, the measurement results of heat exchange efficiency are shown for comparison. As is clear from these measurement results, by periodically reversing the direction of the air passing through the heat exchanger, it is possible to improve the heat exchange efficiency compared to the conventional method.

3 by swinging it periodically through 90 degrees. With the center of the heat exchanger 13 as the rotation axis, the swing is repeated once every 30 seconds as shown by the arrow 14. The time required for swinging is about 1 second.

The flow of air passing through the heat exchanger may be periodically reversed.
