DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for simultaneously exhausting and forcibly supplying air with a single propeller fan in a room for ventilation. Air total heat exchanger consisting of exchange elements (sensible heat
A latent heat type) and a heat exchange type ventilation fan which continuously recovers temperature and humidity and repeats regeneration.

[0002]

2. Description of the Related Art Conventionally, when a single fan is used to ventilate a room, it is merely for exhaust or air supply, and even a fan provided with a forward / reverse switching device cannot simultaneously perform exhaust and air supply. In addition, none of them recovers temperature and humidity and cannot be regenerated, and the load on the cooling and heating equipment increases in proportion to the ventilation rate, which goes against the energy saving policy. In particular, in a house, in addition to the above-mentioned drawbacks, when using any type of fan, the differential pressure between the outside and the room increases in proportion to the amount of ventilation in the room per unit time, making it difficult to open and close doors. Become. In addition, there are drawbacks such as a reduction in fan performance and generation of noise from gaps. In the future, houses are becoming more and more airtight and highly insulated, and as ventilation is regarded as important from the viewpoint of hygiene such as dew condensation, mold and mite, the effects of these have become significant.

[0003]

The problems to be solved are that one fan cannot simultaneously perform forced exhaust and forced air supply in the room, and at this time, the temperature and humidity cannot be recovered and regenerated. The present invention has been made to eliminate these disadvantages.

[0004]

According to the drawings,
The propeller (6) of the fan of the axial flow type has a variable structure in which the mounting angle can be freely set, and the gear (1) rotates about one shaft by rotating and rotating with a gear mechanism.
The propeller (6) is displaced by 90 degrees (rotation) every 80 degrees (revolution) so that the air blowing direction is reversed, and one fan simultaneously performs forced exhaust and forced air supply in the room. Ensure balanced and efficient ventilation. In this case, the displacement position of the propeller (6), in which the air blowing direction is reversed, is not exactly rotated by 180 degrees (revolution), but is calculated and designed so as to be slightly shifted forward or backward depending on the gear ratio of the gear mechanism. The conversion position, which is the boundary line of the air supply, is continuously and gradually rotated. Next, the fan is made of a specially processed paper which has been impregnated with a widely used and well-known moisture absorbent / dehumidifier, and a moisture absorbing / desorbing performance of a porous plastic sheet having fine pores treated. When a detachable total heat exchanger (8) composed of a laminated honeycomb structure element having a large contact area with air per unit volume is attached to a heat exchange material having excellent heat resistance, the total heat exchanger (8) The temperature and humidity are continuously collected and the regeneration is repeated without rotating the
It enables significant savings in cooling and heating equipment and operating costs.
The amount of change in the conversion position is determined based on the optimum tooth ratio so that the heat exchange efficiency of the total heat exchanger (8) can be maximized depending on the fan capacity and the type of heat exchange material. The amount of change is generally in the range of several revolutions per minute to 20 tens of revolutions. In ventilation of a high humidity house or the like in winter, installation of a sensible heat exchanger with a dehumidifying function in place of the total heat exchanger (8) has the effect of suppressing the formation of indoor dew condensation, mold and ticks. If necessary, a detachable dust filter (9) is attached to the casing (7) on the outside air suction side.
The present invention has realized the heat exchange type ventilation fan configured as described above.

[0005]

According to the present invention having the above-described structure, when the motor (1) is operated in ventilation of a house, office, building, etc., one fan can be used for forced exhaust and forced air supply to the room. At the same time, the heat exchange action of the total heat exchanger (8)
Approximately half of the elements store the sensible heat and latent heat of air with high temperature and humidity, and release the stored sensible heat and latent heat into air with low temperature and humidity with the rotational movement of the conversion position between exhaust and air supply. Let it work. In this way, the temperature and humidity are continuously collected and the regeneration is repeated, thereby controlling the temperature and humidity in the room. If it is not necessary to recover the temperature and humidity, if the total heat exchanger (8) is removed from the casing (7), only the forced exhaust and the forced air supply are performed at the same time.

[0011]

As described above, the most important feature of the heat exchange type ventilation fan according to the present invention is to perform forced exhaust and forced air supply to a room at the same time with one propeller fan, but to increase added value. Therefore, in the ventilation of houses, offices, buildings, etc., a total heat exchanger is attached to the propeller, and the temperature and humidity are continuously collected and the regeneration is repeated, thereby cooling and heating equipment costs and operating costs. Has achieved significant savings. More specifically, since the structure is extremely simple and small, it does not require much space for installation, and requires no special work in the same manner as the conventional propeller type ventilation fan installation work. With the axial flow system, the air flow is straight for both exhaust and air supply, reducing the pressure loss of the total heat exchanger, with the small power required for operation of the propeller fan,
The sensible heat load and latent heat load of the outside air are processed with better heat exchange efficiency than the conventional method, and the air supply is pre-cooled and dehumidified in the summer and pre-heated and humidified in the winter to reduce the temperature and humidity of the air-conditioned room. Provide well-balanced exhaust and supply ventilation without changing. In addition, it immediately and automatically follows external air conditions, does not require a switching operation throughout the year such as summer, winter, and intermediate periods, and is extremely economical and exerts its power in constant ventilation. The total heat exchanger has no moving parts, and furthermore, the air flow has a self-cleaning action by a counter-flow method in a boundary layer flow state, so that dust does not accumulate in the element, so there is no clogging, and the heat exchange efficiency does not decrease,
Outstanding durability and requires little maintenance. Further, the total heat exchanger is structurally excellent in soundproofing and vibration-proofing effects, and has an effect of reducing intrusion of outdoor noise, outflow of indoor noise, and hydrodynamic and mechanical noise generated from the propelleran.
As an application example, in the ventilation of high-humidity houses in the winter, if a sensible heat exchanger with a dehumidifying function is installed instead of a total heat exchanger, indoor dew condensation, mold and mite may occur. Has the effect of suppressing. If it is desired to remove the odor of the outside air, a deodorizing effect can be obtained by installing a total heat exchanger made of a heat exchange material capable of absorbing and releasing odor. If it is necessary to further reduce the above-mentioned noise in hospitals, etc., it can be easily realized by using a casing with a structure in which all heat exchangers can be installed on both the indoor and outdoor sides. it can. When used in an area where the outside air is contaminated, even if a dust collection filter is installed on the outside air suction side, there is an effect that clogging does not occur due to the counter flow method. The above effects are
With the momentum rising due to international demands for global environmental protection, the government has a plan to prevent global warming, which will greatly contribute to energy conservation measures.
