BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation system for heating, which effectively recovers exhaust heat from a room and cleans the air circulating in each room to contain moisture so as to have an appropriate humidity. TECHNICAL FIELD The present invention relates to a ventilation device for heating and a system thereof, which can supply clean air to supply air and exhaust heat efficiently by supplying air to each room again instead of air.

2. Description of the Related Art In a conventional heating ventilation system,
It is a mainstream to use various types of heating equipment and heat exchange type equipment in combination as heat exchange ventilation heating as a supply / exhaust method for performing air exchange. The system according to this conventional method is shown in FIG. 4 in place of a method of combining a heat exchanger with each heating device such as pedica heating, floor heating, central heating, FF heating, and the like, and installing each independent heating device. As shown, a method of combining a mantle piece / radiation type FF stove and a heat exchanger is adopted. Further, as a method of heating from under the floor using the hot air central heating method, there is a method of combining an air heater and a heat exchanger as shown in FIGS. 6 and 8. The combination of these circulation paths and devices is shown in FIGS. 5, 7, and 9.

The technique shown in FIG. 4 is a system in which supply air heated by a heat exchanger is further heated by a radiant FF stove and then supplied to each room using a duct to circulate through a house.
The circulated and cooled air is heated again by the heater and circulated again, and this is repeated to heat all the rooms.
However, in rooms far from the heater, auxiliary heating was required.

FIG. 6 shows a system in which supply air heated by a heat exchanger is further heated by an air heater and then supplied to each room using a duct to circulate through a house. This is a means for collecting air under the floor, warming it again with an air heater, and sending it back to each room. In this case, once the circulated hot air is collected under the floor, the temperature under the floor on the first floor rises to enhance comfort, and the arrangement of the underfloor has the advantage of avoiding noise from fans and the like.

FIG. 8 is basically the same as FIG.
The space between the 1st floor ceiling and the 2nd floor is used as a duct space by using the intake / exhaust grill to reduce the construction cost of equipment, and further increase the comfort by raising the temperature of the 2nd floor. Was to try.

Further, as an applied technology for the purpose of improving the efficiency of indoor exhaust and air supply, a technology based on a combination of a heat pump, a heat exchanger, and a heat storage tank, which is disclosed in Japanese Patent Application Laid-Open No. Hei 7-301439, "Heat Exchange Ventilation System" is created. Was what it was.

In the systems according to the above-described conventional methods, the air supplied into each room is taken into the heater again, reheated and circulated, thereby increasing the heat exchange rate in each room. . While the lid and the amount of exhaust from the toilet and washbasin are small, inhale outside air,
It is much larger to constantly circulate the same heated air. Therefore, so-called harmful permanent and sedimentary atmospheric dust such as smoke, mold, mites, carbon dioxide, carbon monoxide, and carbon dioxide from tobacco floating in the air are constantly circulated. It was not enough to collect and remove dust and the like. In addition, what was initially an appropriate indoor humidity by supplying moisture contained in the outside air once taken in, but for the purpose of air circulation only, the supplied air repeats indoor circulation, The initially moistened supply air is heated many times, each time the moisture is absorbed by the heating heat, resulting in a decrease in the humidity of the entire room. This causes the human skin to feel dry, and when circulated for a long time, the skin becomes over-dried, causing various adverse effects.

[0008] Conventionally, an air washer was installed in a room to clean the air in a house, and the air in the room was to be cleaned by passing the air through a cleaning filter. These disadvantages are that they must be installed in each room individually, and as the dust collection effect decreases, the filters must be constantly replaced after a certain period of use.For example, air conditioning systems using high-performance filters Nevertheless, the following inconveniences occur as a result. (1) Particles larger than 0.3 microns can be captured, but particles smaller than 0.3 microns cannot be handled. (2) The performance decreases in proportion to the use time. (3) It takes time to replace the filter. (4) Temperature and humidity adjustment, such as humidifier maintenance, is difficult. As shown in the above-mentioned drawbacks, in particular, floating airborne dust cannot be collected.

[0009] As a conventional ventilation method, indoor air is exchanged by a general ventilation fan.
2. Description of the Related Art With the spread of houses having excellent heat insulation properties, various harms that have not been considered in conventional homes have occurred. Therefore, when indoor air is exchanged by a general ventilation fan, cold outdoor air is taken into the room and warm air is expelled. In other words, by directly introducing cold air into the room, temperature unevenness is created, and dew condensation and overdrying are intentionally generated. In order to solve these problems, various heat exchange type ventilation and heating systems described above have been widely used instead of using general ventilation fans.

[0010]

However, as described above, while recommending highly airtight and highly insulated houses, there are many factors that are harmful to environmental hygiene, and heat exchangers and heating equipment are required. Not only can not remove each dust in the air which is considered harmful,
This leads to widely dispersing the dirty air in each room, and moreover, circulating the indoor air and repeating the heating leads to a decrease in humidity. In order to solve this, a device for directly humidifying must be installed in each room, which is extremely uneconomical.

In particular, formaldehyde, which is a harmful substance, is emitted from an adhesive used for plywood as indoor air pollutants in a house, and the formaldehyde and other organic solvent-based toluene, xylene, ethyl acetate, etc. Human harmful substances are generated over a long period of time in houses such as new houses, condominiums and apartments. In addition to these harmful substances, remove air pollution such as carbon monoxide, carbon dioxide, and odor, and mold and mites caused by the generation of water vapor, especially permanent air dust floating in the air, and smoke from cigarettes or building management. There was no combination of heating equipment reduced below the legal standard value.

The present invention has been made in view of the above-mentioned problems in the prior art, and in order to solve the problems, an indoor relative humidity of 45 to 60% suitable for an indoor environment is efficiently maintained. A device and system for ventilation and heating that can remove or drastically reduce each dust and organic matter in the indoor air by constantly cleaning the air and supply clean air that hardly affects human harm. The present invention seeks to provide and eliminate the aforementioned disadvantages.

[0013]

As a result of various studies to solve the above problems, the above object can be effectively achieved by the present invention. That is, the air circulation cleaning device for ventilation and heating according to the present invention takes in air taken in from the outdoors or air circulated indoors from the suction port 1 and stores it in the lower tanta water tank 2 when the blower 5 sucks the suctioned air. The water and the water are simultaneously sucked, the air and the water are passed through the multiple holes 3a of the punching plate 3 serving as an internal partition, and then passed through a metal filter (demist net) 4 provided in an upper layer portion. The countless holes inside the filter 4 are bubbling to form the metal filter 4.
A mist is formed inside the device can 11 of the punching plate 3 and is sent by the blower fan 6 so that the intake air and water come into contact with each other and dust, smoke,
It is characterized by being able to maintain the relative humidity of 45 to 60%, which is suitable for indoor environment, by cleaning the odor and adding moisture to the supplied air. Provide a configuration for draining and storing again.

Further, in the system according to the present invention, in a ventilation system for heating, by combining an air heater (hot water coil unit) 7 with the above-mentioned air circulation cleaning device, air discharged from the device can be air-cooled. This is a ventilation and heating system characterized in that it is heated in the heater 7 and supplied to each room.

Also, typically, as an air supply / exhaust method, a heat exchanger, which is a device that takes in air from outside air and exchanges heat with warm air internally to supply air when the outdoor air is taken in and exhausted outdoors, is combined. The present invention provides a ventilation and heating system characterized by that, and solves the various problems described above.
