ている。Conventionally, there is a transmission type total heat exchanger as a total heat exchanger used in air conditioning ventilation fans. This uses paper-like moisture permeability and heat permeability as a 24-ton partition plate, and the intake air flow and exhaust air flow alternately pass in a fixed direction between each layer partitioned by the partition plate. By doing so, total heat exchange is performed through the partition plate, and the total heat exchange efficiency is generally 5.
It's as low as 6-6 degrees. Since the direction of the airflow flowing through each layer between the partition plates does not change yet, debris tends to accumulate at the air inlet of the heat exchanger, making it necessary not only to use a filter but also to clean the inlet of the heat exchanger. Regular maintenance is a major cause of reduced heat exchange efficiency and shortened heat exchanger life.

換効率が飛躍的に増大することにある。A partial external view of the example total heat exchanger. In the figure, 1 is a partition plate,
2 is a spacing plate. The spacer plate 2 is made of corrugated kraft paper. FIG. 2 shows a cross section of the partition plate l. This partition plate 1 has heat permeability, moisture permeability, heat storage ability, and moisture storage ability, such as flameproof paper. In FIG. 2, consider a case where the direction of wind flow (arrow direction in the figure) is reversed periodically (here, at intervals of 30 seconds to 1 minute). When the outdoor atmosphere in a hot and humid summer is set to 33°C and 60%, and the indoor atmosphere during cooling is set to 26°C and 50%, if the wind flows in the direction of the arrow in Figure 2, it will flow from the outside to the inside. Some of the sensible heat and latent heat are stored as heat and moisture in the partition plate 1, while others move from the 3rd side to the 4th side in the partition plate 1 and move from the 3rd side to the 4th side of the partition (4th side of m) exposed to the airflow from the indoor side. Some of them are discharged to the outside by riding on the airflow from the indoor side.
The heat of adsorption generated by the adsorption of moisture from the partition plate 1 and the heat of desorption generated by the desorption of moisture from the partition plate 1 (in this case, negative due to an endothermic reaction) are also stored. move towards. The advantage of this method is that by periodically reversing the air flow, the enthalpy brought into the heat exchanger from the outdoor side is discharged to the outdoor side through the partition plate 1. Since a mechanism is added that stores enthalpy in the air and discharges it to the outside when the direction of wind flow is reversed, the total heat exchange efficiency is dramatically increased compared to conventional systems.

It has been confirmed from the measurement results that the oO rotation remains 1° straight. Set the temperature sensor and humidity sensor at the positions A, 11, and 2, and record the changes on the recorder. The hygrometer used makes use of changes in the capacitance of tantalum, and is quick to respond, reaching the equilibrium value of coefficient 96 within a few seconds. Such a test device was placed between two adjacent rooms with constant temperature and humidity, which were adjusted to the indoor and outdoor temperature and humidity conditions, respectively, and the direction of the air flow was periodically changed in a 30-second cycle. A in FIG. 4 shows the result of determining the change in total heat exchange efficiency when the rotation is reversed. In the figure, A' is the average value for 30 seconds. B is the result of using the same device to find the efficiency at equilibrium in the so-called conventional type of total heat exchange system where the air flow continues to flow in a fixed direction without reversing the flow direction using the same-d heat exchanger. It is. As is clear from these results, in this type of air conditioning ventilation method based on the heat storage and transmission method, using a conventional transmission type total heat exchanger,
Compared to the air conditioning ventilation method in which wind continues to flow in a fixed direction, the total heat exchange efficiency indicates the elapsed time from the time when the rotation direction of fan b is switched.

なるということも少なくなる。As described above, in the present invention, sensible heat exchange and latent heat exchange are not only performed through the partition plates, but also those performed by heat storage, moisture storage, heat release, and dehumidification of the element, so that the total heat exchange efficiency can be improved. Compared to the conventional transmission type, it can be made considerably more expensive. However, since the directions of the secondary airflow and the secondary airflow are reversed in an unnatural manner, dust does not adhere to and accumulate at the heat exchanger inlet, which not only eliminates the need for a filter, but also prevents dust from accumulating at the heat exchanger inlet. There is no need for maintenance such as cleaning. This is better, as with the conventional method, there is less chance of clogging occurring on the surface of the element, which shortens the life of the element.

Detailed Description of the Invention The present invention relates to a total heat exchange ventilation system that simultaneously takes in and exhausts outdoor air and exhausts indoor air. A heat exchanger is used to periodically exchange intake and exhaust air (i.e.
By performing total heat exchange ventilation by periodically passing intake and exhaust air through the passage, it has a more efficient total heat exchange capacity and is maintenance-free, making it a more convenient total heat exchange air conditioner. The goal is to provide equipment. There is a transmission type total heat exchanger in Naoki, I Tono A layer V (Yo V) tsu 4LL, V10 Tonagi Kaoden. This uses paper-like material with moisture permeability and heat permeability as the partition plate of the element, and the intake air flow and exhaust air flow alternately pass through each layer separated by the partition plate in a fixed direction. By doing so, total heat exchange is performed through the partition plates, and the total heat exchange efficiency is generally as low as 55 to 60%.Also, the direction of the airflow flowing in each layer between the partition plates does not change, so the heat exchanger Dust tends to accumulate at the air inlet of the heat exchanger, and not only a filter is required, but also cleaning of the heat exchanger inlet is a regular maintenance item. Furthermore, the elements of this type of heat exchanger tend to become clogged, which is a main cause of lowering the heat exchange efficiency and shortening the life of the heat exchanger. The present invention uses the above-mentioned conventional static transmission type total heat exchanger, and
The present invention solves the above-mentioned drawbacks of an air conditioner that performs total heat exchange ventilation by flowing intake air and exhaust air in a fixed direction between each layer of a partition plate. The details of the present invention will be explained below based on FIG. 3, which shows one embodiment. FIG. 1 is a partial external view of a total heat exchanger according to an embodiment of the present invention, in which 1 is a partition plate and 2 is a spacer plate. The partition plate 1 and the flameproof paper spacing plate 2 are made of corrugated kraft paper. Figure 2 shows partition plate 1
Let's think about flow and heat exchange using a cross-section of . The feature of this configuration is that on both sides of the partition plate 1, the air from the indoor side and the outdoor atmosphere of the summer, which is currently hot and humid, are separated by 33"C6O.
%, when the indoor atmosphere during cooling is set to 26°Cr5O and the wind flows in the direction of the arrow in Figure 2, the sensible heat and latent heat flowing from the outside to the inside are stored in the partition plate 1. Some of them become moist, and some of them move from the 3rd side to the 4th side in the partition plate 1 and are carried by the airflow from the indoor side from the 4th side of the partition plate 1, which is exposed to the airflow from the indoor side. Some are discharged to the outside. In addition, part of the adsorption heat generated by the adsorption of moisture to the partition plate 1 and the desorption heat generated by the desorption of moisture from the partition plate 1 (in this case negative due to an endothermic reaction) is also stored as heat, or It moves through the partition plate 1 in the 3-4 direction. When the cycle is switched and the direction of the airflow is reversed, and the airflow on the outside and the airflow on the indoor side are swapped, the sensible heat and latent heat that had been stored near the surface 3 of the partition plate 1 are transferred to the room. It is discharged to the outside of the room along with the low-temperature airflow from the inside. The advantage of this method is that by periodically reversing and replacing the airflow from outside and the airflow from inside, the enthalpy brought into the heat exchanger from the outside is discharged back to the outside through the partition plate 1. In addition, a mechanism is added that stores enthalpy in the partition plate 1 and spacing plate 2 and discharges it to the outdoor side when airflow is exchanged on both sides of the partition plate.
Compared to conventional methods, the total heat exchange efficiency is dramatically increased. FIG. 3 is a schematic diagram showing a method for measuring heat exchange efficiency using this method, and FIG. 4 shows the results obtained. In the figure, 6 is a total heat exchanger, the size of which is 150 x 250°6, and e/ is a grubber type fan, which allows the rotation direction to be changed between forward and reverse directions. The air volume passing through the total heat exchanger 5 is set to 2.5 m''/min in either direction.If the rotation direction of the fan 6.6' is reversed, turn on the changeover switch and , 2 after 4 seconds
It has been confirmed from the measurement results that the constant value is reached at 600 rotations. I set a temperature sensor and a humidity sensor at positions A, 11, and 2, and recorded the changes on the recorder. The hygrometer used makes use of changes in the capacitance of tantalum, and is quick to respond, reaching the equilibrium value of 95 degrees within a few seconds. Such a test device was set between two adjacent constant temperature and constant humidity rooms that were adjusted to the indoor and outdoor temperature and humidity conditions, respectively.
The results of determining the change in total heat exchange efficiency when the direction of the wind flow is periodically reversed in a 30 second cycle (that is, the passage through which air flows from inside the room and the passage through which air flows from outside are switched) are as follows. A' in Figure 3, which is A in Figure 4, is 3
It is normalized as an average value for 0 seconds. B is the result of using the same total heat exchanger 6 to find the efficiency at equilibrium in the case of the so-called conventional type total heat exchange method in which the air flow continues to flow in a fixed direction without completely reversing the flow direction. It is. As is clear from these results, the air conditioning ventilation method using such a heat storage transmission method has a higher total heat exchange efficiency than the air conditioning ventilation method that uses a conventional transmission type total heat exchanger and continues to flow air in a fixed direction. It can be seen that the results are significantly improved. In addition,
In the figure, the horizontal axis indicates the elapsed time from the time of switching the rotational direction of the fan 6, e/. FIGS. 5(a) and 5(b) are schematic diagrams of an embodiment of an air conditioning ventilation fan manufactured using this method, and FIG. 6 is an external view thereof. However, in this figure, the front panel louvers have been removed. In the figure, 12 is a total heat exchanger, a, a'
39 is a sirocco-type fan, which actually has a one-motor, two-fan structure.39 is a louver on the front panel. 1o,
1σ is 71. -2 Closed during outage. Here, the direction of rotation of the fan 8°e is always constant, and the periodic exchange of the airflow passing through the heat exchanger is performed by a system of 900 swings of the total heat exchanger 12. The total heat exchanger 12 is indicated by arrow 1 in the figure.
1, a part of the swing is made in 30 seconds, and the time required for the swing is about 1 second. In addition, Figure 6 (a)
The difference between and (b) is that the heat exchanger is rotated 900 times. The type of air and the direction of flow in the heat exchanger in each state are shown in Figures 6(a) and 6(b). As described above, in the present invention, sensible heat exchange and latent heat exchange are not only performed through the partition plates, but also those performed by heat storage, moisture storage, heat release, and dehumidification of the element, so that the total heat exchange efficiency can be improved. Since the conventional transmission type is also added, the total heat exchange efficiency can be reduced by %/+ ・ −・
