The present invention relates to a waste heat recovery system, and more particularly, after heat storage of an indoor heating or air conditioner, cold or hot outdoor air is introduced into the room to heat exchange with the indoor waste heat (hot or cold air), and then exhausted to the room. As a result, heating (cooling) efficiency can be increased to reduce cooling and heating costs for each season, and cold or hot outdoor air can be stored after heating or reducing the temperature in a basement with relatively constant temperature. A waste heat recovery type that can change the temperature exhausted to the room by exchanging heat with waste heat to further increase cooling and heating efficiency.By exchanging cold or hot outside air with a heat pump, it is a waste heat recovery type that can additionally heat or reduce heat before heat exchange with the stored waste heat. It relates to a ventilation device and a waste heat recovery system using the same.

Globally, high insulation of houses has become a common issue with the aim of reducing carbon and is progressing rapidly. For good insulation, it is essential to increase the sealing performance of the house in order to increase the thickness of the insulation and reduce convection loss.

For this reason, the high airtight performance of recent windows has become an essential element of high insulation houses called passive houses.

Since this high airtightness causes a problem of sharply deteriorating indoor air quality, a forced ventilation system is required, and the ventilation system has a total heat exchange method that can minimize energy loss during forced ventilation.

In particular, respiratory diseases, eye diseases, skin diseases, and other various human health are harmful due to serious air pollution, dust and smoke, regardless of the current population-dense city center as well as shopping districts or industrial complexes. Social problems have been raised due to the occurrence of diseases, and various green movements and environmental clean-up movements are being developed to prevent air pollution.

Various air ventilation systems have been developed to ventilate fresh air indoors from such a harmful environment.

1 to 6, the waste heat recovery system 100 according to an embodiment of the present invention recovers the waste heat of the indoor heating heater (heater) in winter and heat storage, and then heats the outside air heated by heat exchange with cold outside air. Is exhausted to the second room (4), which is a residential room, or by recovering the waste heat from the indoor air conditioner (cold air) in the summer season and heat-exchanging the heat with the hot outside air into the second room (4). By exhausting, it is possible to reduce the operation of the air conditioner or the heater in the second room 4 for each season, thereby reducing power consumption and improving cooling and heating efficiency.

As an example, the following describes the waste heat recovery system 100 according to the present invention, limited to increasing the heating efficiency in winter.

The waste heat recovery system 100 according to the present invention includes a heat exchange outside air inlet 200, a waste heat recovery type ventilation device 300, and a heat pump 800.

The heat exchanger outdoor air inlet 200 serves to allow the outside air, which is sub-zero in the winter season, to flow into the interior, particularly, the first interior 2.

At this time, the heat exchange outside air inlet 200 includes a filter unit 210 and a heat exchange corrugated pipe 220.

In particular, the first interior 2 maintains the indoor temperature within a constant temperature range for all four seasons, or at least becomes higher than the temperature of the outside outside air in winter.

In detail, the first room 2 is a basement of a house, and according to the basement, the room temperature is maintained at a constant temperature within a set range. Of course, the first room 2 is a room having a temperature higher than the temperature of the outside air outside in winter, and is not limited to a location.

The filter unit 210 serves to filter foreign substances, such as (fine) dust, before the outside air flows into the first room 2. As the outside air passes through the filter unit 210, the outside air flows into the first chamber 2 in a purified state. Of course, the filter unit 210 can be applied in various ways, such as a HEPA filter and an electric precipitator.

The heat exchange corrugated pipe 220 serves to transfer and guide the filtered outdoor air to the waste heat recovery ventilator 300 and to exchange heat with the air in a constant temperature state in the first chamber 2. Accordingly, the heat exchange corrugated pipe 220 is made of a material having excellent heat transfer efficiency, such as copper (Cu). In addition, the heat exchange corrugated pipe 220 may form wrinkles (corrugations) on the circumferential surface in order to increase the heat exchange area of the air in the first room 2 and the purified outside air. Of course, the heat exchange corrugated pipe 220 may be formed in various shapes.

Further, the heat exchange corrugated pipe 220 may be arranged along various trajectories in the first interior 2 and may be fixedly installed on the interior ceiling of the first interior 2.

In particular, it is assumed that the heat exchange corrugated pipe 220 is arranged in a zigzag type while in contact with the ceiling of the first interior 2 corresponding to the floor of the second interior 4. Through this, the warmth of the floor of the second chamber 4 may be transmitted to the heat exchange corrugated pipe 220.

At this time, the filter unit 210 may be buried in a wall of a building such as a house, or may be provided in the heat exchange corrugated pipe 220.

In addition, although not shown, the filter unit 210 or the heat exchange corrugated pipe 220 may be provided with a shut-off valve to regulate the introduction of external air into the first chamber 2.

On the other hand, the waste heat recovery type ventilation device 300 is operated by operating a heater (not shown) in the second room 4 while passing a predetermined heated outside air after heat exchange with the indoor air in the first room 2 It stores the generated heat (waste heat) and induces further heating of the outside air.

In particular, the waste heat recovery ventilator 300 is provided in the second residential room 4 or other room where the heater is operated and transfers heat, and after inhaling the heated waste heat in the heated state of the second room 4 In a heat storage state, heat exchange with the outside air introduced through the heat exchange corrugated pipe 220 is induced. As a result, the outside air passing through the waste heat recovery ventilation device 300 is heated by receiving heat from the stored waste heat.

At this time, as the outside air and waste heat naturally flow into the waste heat recovery ventilator 300, a separate power for forced flow of the outside air and heat is not required, thereby reducing power consumption.

In detail, the waste heat recovery type ventilation device 300 includes a lower chamber 400, a middle chamber 500, a heat storage unit 600, and an upper chamber 700.

The lower chamber 400 serves to allow outside air heated through the heat exchange corrugation pipe 220 to flow into the interior to heat storage and heat exchange of waste heat, and to guide the exhaust heat reduced after heat exchange to the outside.

To this end, the lower chamber 400 has a cylindrical interior divided along the circumferential direction into at least one first lower room 412 and at least one second lower room 414 by a lower partition 410 to provide outside air and waste heat. Separate the flow passage. In addition, the first lower room 412 forms a first lower opening 413 to receive outside air from the heat exchange corrugated pipe 220, and the second lower room 414 allows the waste heat after heat exchange to be discharged outdoors. A second lower opening 415 is formed.

Accordingly, the outside air that has passed through the heat exchange corrugated pipe 220 flows into the first lower room 412 through the first lower opening 413 and then heats up through heat storage of the heat storage unit 600 and is heated, and then the upper chamber Exhausted through 700.

Then, the waste heat in the second interior 4 flows into the upper chamber 700 and then heats up in the heat storage unit 600 and is then exhausted to the outside through the second lower opening 415.

Of course, after inhaling the outside air to the second lower room 414, heat storage through the heat storage unit 600 and then exhausted to the first lower room 412, the first lower room 412 and the second lower room ( 414) may be simultaneously intake or exhaust.

For convenience, it is assumed that the outside air that has passed through the heat exchange corrugation pipe 220 is inhaled into the first lower room 412 and then is heated by the heat storage unit 600 and then exhausted to the first upper opening 713 of the upper chamber 700. .

In addition, the lower chamber 400 is fixed without rotating in the circumferential direction. Of course, the lower chamber 400 can be deformed into various shapes.

In addition, the middle chamber 500 is provided on the upper portion of the lower chamber 400 and serves to guide heating through heat storage while passing the outside air flowing into the first lower opening 413 of the lower chamber 400. Accordingly, the lower chamber 400 is formed to be opened toward the middle chamber 500.

In addition, the middle chamber 500 forms a plate 510 over the entire inner surface. Accordingly, the middle chamber 500 is divided up and down by the plate 510. In addition, the plate 510 forms communication holes 512 that are spaced at predetermined intervals in the circumferential direction.

In particular, the middle chamber 500 is disposed on the open upper side of the lower chamber 400 and is rotatably provided in the circumferential direction. Further, the lower partition 410 may be disposed in contact with or close to the plate 510.

So, the outside air introduced into the first lower room 412 naturally flows toward the upper chamber 700 through the corresponding communication hole 512, and the outside air above the plate 510 corresponds to the second lower room 414 It naturally flows toward the second lower room 414 through the communication hole 512.

At this time, as the middle chamber 500 is rotated in the circumferential direction, the communication holes 512 of the plate 510 are divided, alternately for each division, so as to correspond to the first lower room 412 and the second lower room 414. Is placed.

Of course, outside air is provided with at least one blower (not shown) throughout the entire waste heat recovery system 100 other than the waste heat recovery ventilator 300 so that the outside air can naturally flow inside the waste heat recovery ventilator 300 Flow) by force.

Of course, the middle chamber 500 can be deformed into various shapes.

In addition, the middle chamber 500 can be rotated in the circumferential direction while being sealed from the upper side of the lower chamber 400 by the packing bearing 530.

Meanwhile, the heat storage unit 600 is provided on the plate 510 so as to correspond to each of the communication holes 512, and while circulating inside the lower chamber 400 and the middle chamber 500, the first lower opening 413 or It serves to supply heat as heat storage to the outside air that is intake or exhausted through the second lower opening 415.

In addition, the upper chamber 700 has a cylindrical interior divided along the circumferential direction into one or more first upper rooms 712 and one or more second upper rooms 714 by an upper partition 710. The flow path is separated, and the flow direction of the indoor waste heat passing through the heat storage unit 600 corresponding to the first upper room 712 and the outside air passing through the heat storage unit 600 corresponding to the second upper room 714 It is guided differently or in the same way, and the waste heat in the room is recovered and introduced. At this time, the lower partition 410 and the upper partition 710 are fixed to the polygonal shaft 524, which will be described later, and are maintained in a state located inside the corresponding lower chamber 400 and the upper chamber 700.

In other words, the upper chamber 700 is provided on the upper portion of the middle chamber 500, is formed to be open in the direction of the middle chamber 500, and is sealed by the packing bearing 530 in the circumferential direction of the middle chamber 500 Guide rotation. At this time, the upper chamber 700 is not rotated and is in a fixed state.

In particular, the upper chamber 700 allows the outside air heated while passing through the corresponding heat storage material 630 of the heat storage unit 600 to be exhausted to the first upper opening 713 through the first fish opening 713, The waste heat in the room introduced through the second upper opening 715 is flow-guided to the heat storage material 630 of the corresponding heat storage unit 600. In particular, the waste heat in the room that has been heat-stored in the heat storage material 630 is exhausted to the outside through the second lower opening 415 of the lower chamber 400.

Of course, the lower chamber 400, the middle chamber 500, and the upper chamber 700 may be formed in one cylindrical shape.

On the other hand, the heat storage unit 600 includes a frame 610 and a heat storage material 630.

The frame 610 is formed to be open at least in the vertical direction, and is detachably disposed on the plate 510 so as to correspond to the communication hole 512 one-to-one. And, the frame 610 is made of a frame (frame) to reduce its own weight. Thus, the frame 610 is formed to open the upper and lower and circumferential surfaces. Of course, the frame 610 can be deformed into various shapes.

In addition, the heat storage material 630 is disposed on the plate 510 so as to correspond to the upper portion of the communication hole 512 inside the frame 610 or inside the frame 610. In this case, the heat storage material 630 may be disposed as a single layer or may be laminated as a multilayer.

And, each of the heat storage material 630 forms a plurality of heat storage holes 632 in the flow direction of outside air and waste heat. Of course, the heat storage holes 632 of each heat storage material 630 are not limited to the diameter and number.

In particular, the adjacent frame 610 may be thermally insulated by the heat insulating material 640 so that outside air and heat flow intensively to the heat storage hole 632 of the heat storage material 630. That is, the insulating material 640 surrounds each of the frames 610 inside the middle chamber 500 and is filled between the adjacent frames 610. Of course, the insulating material 640 may be applied in various ways.

In addition, although not shown, the adjacent frames 610 may be constrained to each other and fixed in position to the corresponding communication holes 512.

As a result, after the outside air introduced into the first lower room 412 is heated while passing through the heat storage material 630 of the corresponding heat storage unit 600 through the communication hole 512, the upper chamber 700 is It is exhausted through 1 upper room 712.

Then, the indoor waste heat flows into the upper chamber 700 through the second upper opening 715 of the second upper room 714 and then passes through the communication hole 512 of the corresponding heat storage material 630. Thereafter, the waste heat in the room is exhausted to the outside through the second lower opening 415 of the second lower room 414.

Of course, the upper chamber 700 is not limited to the number of the first upper room 712 and the second upper room 714.

In addition, as the middle chamber 500 is rotated in the circumferential direction by a set angle regularly or irregularly, all the heat storage materials 630 alternately, some of them are deprived of heat to the outside air, and the rest is caused by waste heat in the room. Heats up.

Meanwhile, the middle chamber 500 between the lower chamber 400 and the upper chamber 700 is independently rotated in the circumferential direction by the driving unit 520.

In an embodiment, the driving unit 520 includes a driving motor 522, a polygonal shaft 524 and a polygonal hole 526.

The driving motor 522 is fixedly installed on the upper side of the upper chamber 700 and generates a driving force.

The polygonal shaft 524 is connected by the driving motor 522 and rotates in the circumferential direction. Then, the polygonal shaft 524 is simply inserted into the upper chamber 700.

In addition, the polygonal hole 526 is formed in the axial direction of the polygonal shaft 524 in the center of the middle chamber 500. At this time, the polygonal shaft 524 and the polygonal hole 526 form a polygonal cross section of the same shape. Thus, when the polygonal shaft 524 is rotated by receiving the driving force of the driving motor 522, the middle chamber 500 is rotated in the circumferential direction by the polygonal shaft 524.

In addition, the heated outside air exhausted through the first upper opening 713 of the first upper room 712 of the waste heat recovery ventilator 300 is heat-exchanged with the heat pump 800 and may be further heated.

That is, the outside air heated through the heat storage material 630 passes through the heat pump 800 to exchange heat with the heat dissipation side to obtain heat. In this case, the heat pump 800 may use groundwater or refrigerant higher than the outdoor temperature as a heat medium. In addition, the heat pump 800 is composed of an indoor unit and an outdoor unit, or is compatible with various heat exchange modules.

Accordingly, the finally heated outdoor air is exhausted to the space of the second interior 4, thereby heating the air of the second interior 4. Thus, heating costs due to operating a separate heater are reduced, and heating efficiency is increased.

At this time, at least one indoor air supply device 6 is provided on the ceiling of the second interior 4 so that the heated outdoor air is exhausted toward the lower side of the second interior 4 through the interior air supply device 6.

In addition, the second interior 4 has an indoor arrangement module 8 on the floor. Thus, the waste heat in the second room 4 is supplied to the inside of the upper chamber 700 of the waste heat recovery ventilation device 300 through the indoor heat distribution module 8. At this time, the indoor arrangement module 8 is provided on the floor of the second interior 4 and provides a cyclone or waste heat flow capable of supplying only the heat obtained by filtering out dust or foreign substances in the second interior 4 to the upper chamber 700. It can be applied in various ways such as guiding traps.
