Description

TECHNICAL FIELD [0001] The present invention relates to a counterflow ventilating apparatus using a heating element,

The present invention relates to a countercurrent ventilator using a heating element. More particularly, the present invention relates to a countercurrent ventilation apparatus using a heating element which is manufactured in a compact shape so as to enable miniature manufacturing of a ventilation apparatus, which can reduce manufacturing cost, can be easily handled and installed, .

In general, the interest in indoor air is increasing, and especially in the situation where sick house syndrome problem caused by various harmful substances in new buildings becomes serious, the importance of ventilation is emphasized. However, due to energy saving, .

Therefore, it supplies the fresh outside air required for a comfortable living environment in a residential building and discharges the contaminated internal air. In particular, it recovers heat and moisture discarded at the time of ventilation of the winter season and the summer season, The development of a ventilation and air supply system using an all-air heat exchanger that saves energy is provided to provide a pleasant and healthy life in high airtight and high insulation houses

This total heat exchanger recovers the indoor energy that is lost due to the ventilation by the heat exchange mechanism and transfers it to the incoming air. It can be minimized.

Meanwhile, the ventilation units developed and applied in Korea are classified into two or three types, but they are generally developed as a duct type for a residential building, making it difficult to directly apply the ventilation unit to a flat-plate type apartment. However, according to the Fire Service Act revised in 2006, it is required to develop a ultra slim type ventilation unit because a ceiling land space of about 200mm is secured in a flat plate type apartment.

1 is a view showing a ventilation unit using a heating element according to the related art.

As shown in the drawing, the ventilation unit using the heating element of the related art is installed inside the casing 110, and has a structure in which the spacer 122 and the liner 124 are sequentially laminated, and each spacer 122, An inlet core 112 formed at one side of the casing 110 to receive the outside air and an outlet 112 through which the room air is discharged to the outside, An air supply fan 130 and an exhaust fan 140 for forcibly introducing and discharging air into and out of the inlet 112 and the outlet 114 and an inlet 112 and an outlet 114 and an element core And an air supply duct 118 and an air discharge duct 116 connected to the casing 110 with the first and second indoor units 120 and 120 interposed therebetween.

Since the element core 120 is stacked so that the spacers 122 and the ventilation passages 126 of the liner 124 cross each other in an orthogonal direction, a separate ventilation passage 126 is formed in the orthogonal direction And the inlet 112 and the air supply duct 118 communicate with each other through one ventilation passage 126 and the outlet 114 and the exhaust duct 116 communicate with each other through the other ventilation passage 126 .

In the element core 120 located in the middle of the ventilation process, heat is exchanged while each air passes, and the enthalpy held by the inner air is transferred to the outside air and recirculated to the room. As a result, the problem of the normal ventilation, in which the cooled air in the room or the warmed air in the heated air flows out, is complemented, and the cooling / heating energy is remarkably reduced.

However, the ventilation unit using the heating element according to the related art has a problem that the heat exchange efficiency with respect to the heat transfer area is small and the size is increased with respect to the same heat exchange capacity.

The element core 120 composed of the spacer 112 and the liner 114 intersecting each other in the direction orthogonal to each other is inevitably required to be manufactured at a high manufacturing cost due to complicated mounting and manufacturing processes and the heat exchange There is a problem that not only the power consumption of the blower is increased but also the thermal efficiency is lowered.

In addition, when applied to a slim-type ventilation unit, since the product height is lowered in the conventional type without technological development, the width and width of the product naturally increase due to the efficiency problem.

On the other hand, Prior Art Document 2 discloses a countercurrent heat exchanger for air. However, this countercurrent heat exchanger has a problem in that productivity is remarkably reduced due to difficulty in producing the element core for air flow, and a header for suction and discharge of air has to be separately manufactured.

Here, the lower part of the spacer 212 constitutes a membrane 214 in which indoor and outdoor air mixing, that is, contaminated air and purified air is prevented from being mixed, heat and moisture are transferred to perform total heat exchange, The spacer 214 is bonded to the lower portion of the spacer 212 by adhesion so that a heat exchange passage 216 is formed between the spacer 212 and the membrane 214 to allow air to pass through a predetermined space .

The element core 210 is made of polypropylene (PP) or a paper material. The element core 210 is formed of a plurality of elements spaced apart from each other by a predetermined distance in the ventilation device body 310 so as to allow the air on the indoor side to flow out to the outdoor side, So that air can be exhausted to the indoor side.

That is, the element core 210 of the present invention is positioned such that both ends thereof are respectively located at the inlet 312 and the outlet 314 formed on one side of the ventilator body 310, as shown in FIG. 3 A plurality of inlet element cores 220 installed at a predetermined distance from the upper side to a lower side of the inlet element core 220 and having opposite ends connected to the other side of the ventilation device body 310, And a plurality of supply-side element cores 230 installed to be positioned in the exhaust part 319. The supply-

The element core 210 of the present invention is constituted such that the inflow-side element core 220 and the air supply-side element core 230 are sequentially stacked and fixed to the ventilator body 310 in a staggered manner alternately .

For example, when the inlet element core 220 is installed so as to be located at the uppermost end of the inlet portion 312 of the ventilator main body portion 310, then the air supply element core 230 is connected to the air supply portion 317 The inlet element core 220 and the air supply side element 300 are provided so as to be positioned on the exhaust part 319 and then the inlet element core 220 is again attached to the lower surface of the air supply element element core 230. [ And the cores 230 are configured to be alternately installed on the ventilator body 310. [

At this time, the direction of the spacer 212 of the inlet element core 220 and the direction of the heat exchange passage 216 of the air supply element core 230 is configured to be installed in a horizontal direction with respect to each other, Or the direction in which the air on the outdoor side is supplied is positioned in a direction opposite to each other.

The ventilation device main body 310 is configured such that the above-described element cores 210 are alternately installed alternately one by one so that ventilation and heat exchange of the indoor air can be performed through the ducts of the houses, Element.

The ventilation device main body 310 is formed at one end and includes an inlet portion 312 through which the air on the indoor side is installed and a rear portion on the rear side of the inlet element core 220, And a discharge portion 314 for discharging the air on the indoor side to the outside is provided.

The ventilation device body 310 has a supply portion 317 formed at the other end and provided with a rear portion of the air supply element core 230 to supply air on the outdoor side, And a discharge portion 319 for discharging the air on the outdoor side to the indoor side is provided.

That is, the inlet 312 and the outlet 317, and the outlet 314 and the outlet 319 are formed in directions opposite to each other.

The discharge unit 314 and the exhaust unit 319 are preferably formed with a discharge flange 322 and an exhaust flange 332 connected to the duct so as to discharge or exhaust the air outside the room.

When the indoor air introduced through the inflow-side element core 220 formed in the inflow portion 312 is discharged to the outside by the discharge portion 314, the air supply-side element core The discharge header 320 is formed so as to prevent the discharge header 320 from flowing into the discharge side.

When the outdoor air supplied through the air supply element core 230 formed in the air supply unit 317 is exhausted to the indoor side by the exhaust unit 319, the outdoor air can be prevented from flowing into the inlet- An exhaust header 330 is formed.

That is, the discharge header portion 320 is formed in a space between the discharge portion 314 and the supply portion 317, and the supply side element core 230, which is connected to the supply portion 317, And the exhaust header portion 330 is formed in a space between the inlet 312 and the exhaust portion 319 and a space apart from each other of the inlet element cores 220.

In this case, the element core 210 functions as a countercurrent heat exchanger. In the element core 210, as shown in FIG. 7, when the unit of air transfer (size of the heat exchange) in the countercurrent heat exchange is 3 , And the efficiency (heat exchange efficiency) thereof is 76%.

Thereafter, when indoor air having undergone the primary heat exchange is discharged through the discharge portion 314, secondary heat exchange is performed by the cross flow heat exchanging portion B side of the discharge header portion 320, and the discharge is performed to the outdoor side will be.

In order to supply outdoor air to the room, the air supply unit 317 and the air supply unit 319, which are provided in the exhaust unit 319, are operated by the operation of the air supply blower 324 connected to the air supply unit 317, When the outdoor air having the primary ventilation is discharged through the exhaust part 319, the outdoor air is supplied to the element core 230 through the primary ventilation through the cross-flow heat exchanger, The air is exhausted to the indoor side.

In this case, the cross-flow heat exchanger functions as a cross-flow heat exchanger. In the cross flow heat exchanger, as shown in FIG. 8, when the air transfer unit (heat exchange size) (Heat exchange efficiency) shows an efficiency of 47%.
