Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to forcibly ventilate a room while cooling and heating it, and uses a heat exchanger for heating and cooling and a fan for blowing air to remove toxic gas components C02 from the air through an absorption reaction.
We propose a simple and inexpensive indoor air conditioner unit consisting of a clean filter that can absorb and remove NO2 and S02 and a ventilation tube that minimizes heat energy loss due to ventilation.

In recent years, with the spread of new construction materials, more and more rooms are becoming highly airtight.

For this reason, conventional heating and cooling systems rarely require exchange of indoor air, and a separate means of forced ventilation has become necessary.

To solve this problem, a separate type air conditioner has recently been proposed that allows indoor units to cool and heat the room while also sucking in outdoor air and exhausting indoor air.
In addition to increasing the maintenance cost because of the need for multiple units, the structure of the passage becomes complicated like a maze, and the structure is large and high.In addition, the opening in the wall for ventilation and the through hole for connecting piping to the outdoor unit The disadvantages are that two or more are required or the opening size is large enough to install an axial ventilation fan, which increases the scale of the construction work and increases the construction cost.

The present invention can be easily installed by simply providing a single hole with a diameter of about 10c1rL in the wall, and has almost the same configuration as a conventional air conditioner, that is, the outside air outlet is located in the space between the indoor air intake and the fan. The air supply passage and the exhaust passage in which the outdoor air supply port is located between the fan and the heat exchanger are formed by stacking long and narrow ducts in parallel at intervals. An indoor unit that is composed of a cleaning filter made of a composition or catalyst powder that can absorb and remove components, circulates the room, cools and heats the room, forcibly ventilates the room, and recirculates the clean air. This is a proposal.

FIG. 1 shows an embodiment of the present invention, in which 1 is a main body having a ventilation pipe 3 on the surface facing a wall 2, an impeller 5 driven by a motor 4, an exhaust passage 60, and an outdoor air supply lower. The back plate 1a of the main body 1, the fan casing 8, and a heat exchanger 9 for cooling or heating the room are built in, and the air intake port 10 is equipped with a dust removal filter 11 made of a fibrous material such as non-woven fabric or polymer. A clean filter 12 made of activated carbon or a composition containing activated carbon, an alkali, and a cement agent as main components or a granulated molded catalyst is disposed, and a platinum metal element is added to the composition of the clean filter 12 of the intake port 10 at the discharge port 13. A clean filter 14 formed of catalyst powder supporting one or more of the following is attached, and the clean filter 1
A small groove 15 is formed in 2.14.

16 is an air supply passage for outdoor air, and a dust removal filter 1
7 and the clean filter 18 through the outside air suction port 19 in the passage.
The duct 20 is located close to the duct 20 and is formed of an elongated duct 20 that is open at both end faces in the flow direction.

The duct 20 is made of synthetic paper mixed with metal fibers or carbon fibers, or a thin metal plate with fine pores, or synthetic Japanese paper mixed with short fibers impregnated with lithium compounds or organic substances such as rayon fibers or polyacrylontrile fibers. It is made of a total heat exchange material such as aluminum foil, and the total heat is exchanged between the air in contact with both sides through the duct surface, or half of the duct is made of a material such as paper with high latent heat exchange efficiency and the other half is It is constructed of a material with good sensible heat exchange efficiency, such as metal foil, and performs total heat exchange.

Reference numeral 21 denotes a slit-shaped outside air blowing port that sucks outside air from the outside air suction port 19 located outdoors and blows it out into the fan, and is located between the fan casing 8 and the intake port 10 of the main body 1, and is formed by the duct 20. The air supply passage 16 is configured to penetrate inside the fan discharge passage.

Note that the exhaust passage 6 communicates between a slit-shaped outdoor air supply port I arranged on the upstream side of the heat exchanger 9 on the back side of the main body 1 and an outdoor discharge port 22 located in the chamber, and is formed by a gap in the duct 20. be done.

That is, the ventilation tube 3 is configured such that a plurality of the ducts 20 are stacked in parallel at intervals within the ventilation tube 3 so that the inside of the duct 20 becomes the air supply passage 16, and the gap between the ducts 20 becomes the exhaust passage 6. The supply and exhaust passages 6 and 16 are integrally formed.

A heat exchanger 9 cools or heats the air passing through the heat exchanger, and is installed near the discharge port 13.

FIG. 2 shows one embodiment of the construction of the cleaning filters 12, 14, 18.

Reference numeral 23 is a filter assembly of powder of several 1000 microns of a composition or catalyst that absorbs and removes toxic gas components from the air through an absorption reaction, and has finely bent communication ports between the powders.

The small groove 15 is a small groove whose depth is greater than the overall depth A, and the small groove has a shape that gradually decreases from the upstream side to the downstream side of the wind.

The powder filter assembly 24 and the small grooves 15 are molded into one body by powder press molding or the like to form a honeycomb-shaped or harmonica-shaped filter.

25 is a filter frame to which a large number of filter assemblies 24 are fixed, and a filter material having a low pressure loss and a large contact surface with air is fixed therein.

The cleaning ability of the above-mentioned cleaning filters 12゜14, 18, 24 is mainly based on a composition obtained by kneading and granulating potassium carbonate, calcium hydroxide, powdered activated carbon, and calcium sulfate in a weight ratio of 3:3:2:20. In one embodiment, 90% or more of NO2 is mainly absorbed and removed.

Also, powdered activated carbon, lime aluminate, and potassium carbonate are 3:6.
In an example in which the main component is a catalyst in which the catalyst is kneaded and molded in a weight ratio of 1:1 and has platinum and baradium supported on the frt'B body, about 85% of CO is absorbed and removed at room temperature.

In such a configuration, when the impeller 5 is rotated by the motor 4, an air flow is generated as indicated by the arrow in FIG.

Fibrous or particulate matter such as dust contained in the indoor air a is removed by the dust removal filter 11, and by passing through the small holes of the cleaning filter 12, toxic gases such as NO2 and CO in the air are removed. Most of the components are absorbed and removed and sucked into the fan.

Outdoor air is sucked into the air supply passage 16 from the outdoor air suction port 19, and substances such as dust in the outdoor air are removed by the dust removal filter 17, and toxic gas components NO□, S0 from car wash gas etc. are removed.
2 is absorbed and removed when it passes through the clean filter 18 to become clean air, which flows through the air supply passage 16 and exchanges total heat with the air flowing through the exhaust passage 6 through the wall of the duct 20 before reaching the outside air supply port. The air is sucked into the fan in a state similar to that of indoor air a.

The clean air drawn in by the fan from indoors and outdoors is
The mixture is mixed within the impeller 5 and fan casing 8, and the air is blown to the fan discharge side.

- The air on the fan discharge side contains almost no toxic gas components or substances such as dust, and the temperature and humidity conditions are almost the same as those of the air from the intake port 10.

The air C discharged into the room is cooled or heated while the air in the fan discharge passage passes through the heat exchanger 9, and passes through the cleaning filter 14 in the discharge port 13 to remove remaining C02NO2 and S02. The toxic gas components such as gases are absorbed and removed, resulting in fresh cold or warm air.

This fresh cold air or hot air is then circulated within the room to cool and heat the room.

On the other hand, the exhaust air to the outside flows through the exhaust passage 17 before being heat exchanged in the heat exchanger 3 according to the fan discharge pressure from the outdoor air supply port 1 arranged on the back plate of the main body 1, and flows through the exhaust passage 17 through the wall of the duct 20. The air is discharged outside from the outdoor outlet 22 while exchanging temperature or humidity with the outdoor air flowing through the air supply passage 16 through the air supply passage 16 .

Therefore, by simply rotating the impeller 5, the indoor air is circulated, cooled or heated by the heat exchanger 9, and blown into the room to thoroughly cool and heat the room.At the same time, the outdoor air is cooled in the ventilation pipe 3. The outside air is cooled or heated by the exhausted air and drawn into the fan, and the outside air drawn into the fan is mixed with indoor air from the intake port 10 and blown into the room through the heat exchanger 9. At the same time, the mixed air on the fan discharge side is exhausted to the outside, and it is possible to simultaneously perform forced air supply and exhaust from the room while providing heating and cooling.

As explained above, the separate air conditioner of the present invention removes substances and toxic gas components contained in indoor air and outdoor air by using a cleaning filter and a dust removal filter that are emitted in each passage. The air is sucked in, mixed in a fan, and exhausted outside while partially exchanging all heat with the supplied outdoor air. At the same time, the air is heated or cooled in a heat exchanger and blown into the room. It is an indoor unit for air conditioning and heating, and ducts using total heat exchange material or latent heat exchange material and sensible heat exchange material are stacked in parallel at intervals in a ventilation cylinder of about 10 crIl square to create an air supply passage and an exhaust passage. The outside air inlet of the ventilation tube is opened into the space between the indoor air intake and the fan casing, and the outdoor air inlet is arranged on the back plate of the main body.
While cooling and heating, simultaneous forced air supply and exhaust ventilation in the room is achieved with a single fan without heat loss, resulting in an excellent effect.
