    Prefabricated heat recovery ventilation system of residential building
    The present invention relates to a prefabricated heat recovery ventilation system of a residential building, and more particularly, in a residential building, the heat exchanger and the fan portion are assembled in a prefabricated manner, so that the fan can be installed outdoors, thereby reducing the noise problem caused by the operation of the fan. The present invention relates to a heat recovery ventilation system for a residential building that eliminates, improves the heat energy recovery efficiency of a heat exchange element, saves heating energy, and reduces a relative humidity difference between indoors and outdoors using an absorbent.
    At present, buildings are becoming more airtight and insulated due to the problem of energy saving. On the other hand, for the health of the occupants, general office buildings, etc. regulate the amount of ventilation required to reflect the amount of fresh air introduced in the design of the air conditioning system.However, in residential buildings, such ventilation regulations are weak, and the ventilation for indoor air is also natural ventilation or kitchen. The situation is dependent only on the local exhaust of the toilet.
    In other words, current apartments use forced exhaust systems in some spaces, such as bathrooms and kitchens, but rely only on non-powered aspirators on the rooftop in the process of discharging air from the interior to the outside. Since the pressure difference is not constant from layer to layer, the effect is not constant for all generations.
    In order to solve this problem, a system has been developed for natural ventilation only for a living room, which is a part of the indoor space, but such a ventilation system is expected to be almost expecting the ventilation effect as it is covered by shields such as curtains or blinds installed in the room. It's hard.
    In addition, although a small heat exchange type ventilation system has been proposed, most of the conventional ventilation systems are manufactured in a form of simply attaching an integrated package type heat exchanger to be applied to a planar state having a balcony structure like a current apartment. There was a significant problem in the introduction and uniform distribution of air flow into the room as a whole, and because the fan and the heat exchange element are integrated, there is a problem that the volume is large and there is a limit to the applicable space.
    In addition, the opening and closing of the door is unnatural due to the pressure difference between the indoor and outdoor, and the discomfort may be caused to the occupants, and the integration of the fan and the heat exchange element may be beautiful in terms of design. Due to the limitation of the noise caused by the operation of the fan had a serious problem.
    Therefore, the present invention has been made to solve the problems of the prior art as described above, the object of the present invention in the residential building, by configuring the heat exchanger and the fan portion as a prefabricated, so that the fan can be installed outdoors, To solve the noise problem caused by the operation of the fan, to improve the heat energy recovery efficiency of the heat exchange element to reduce the heating energy, and to provide a heat recovery ventilation system for residential buildings to reduce the relative humidity difference between indoor and outdoor using the absorbent. .
    Another object of the present invention is to control the operation of the fan automatically according to the change in the concentration of carbon dioxide in the room, and in response to the change in the cross-sectional area of the heat exchange element, the air supply fan and the exhaust fan at different speeds so as not to generate negative pressure in the room. It is to provide a heat recovery ventilation system that is controlled in a range.

    The present invention introduces a total heat exchanger (11) in order to save the heating energy in winter by supplying fresh outside air to the room to improve the indoor air environment, as well as to recover the heat energy lost during ventilation to reuse the room heating.
    In addition, the present invention introduces a duct-type structure in consideration of aesthetics in order to be able to supply fresh outside air to not only a part of the indoor space but also the entire living space in a residential building, and at the same time using a heat exchange element 21 made of a hygroscopic material Make sure to reduce the difference in relative humidity between indoors and outdoors.
    In addition, the present invention is installed so that the air supply fan and the exhaust fan duct end portion is provided in direct contact with the outside air in the farthest part of the actual living space (for example, stairs of the building), the air supply fan ( 12) and the exhaust fan 19, at the same time to install a light-absorbing sound absorption filter at a predetermined position to minimize the noise problem, which is the biggest problem that can appear during forced ventilation in residential buildings.
    Such features of the present invention will become more apparent by the specific structure of the present invention described below.
    In the present invention, the air supply fan 12 for supplying air to the room and the exhaust fan 19 for discharging the air of the room to the outside are installed in a position that can directly contact the outside air. Here, the air supply fan 12 and the exhaust fan 19 may be configured to be operated by each drive motor, or one fan is polluted while the two fans are simultaneously rotated in the same direction by one drive motor. It is responsible for the function of discharging the indoor air to the outside, the other fan may be configured to serve to supply the fresh air to the room.
    In addition, the heat exchanger 11 is installed separately from the fan according to the plane or structural form of the residential building to be installed, the heat exchange element 21 is embedded in the heat exchanger 11 to recover the heat energy.
    In addition, a carbon dioxide sensor 22 that can sense the carbon dioxide concentration of the air discharged from the room is installed at a predetermined position of the ventilation duct 16, according to the concentration of carbon dioxide detected by the carbon dioxide sensor 22. The fan speed control unit 23 for adjusting the air volume is provided. The fan speed controller 23 may be configured such that the air supply fan and the exhaust fan are at different speeds, that is, in a similar range of the air supply air flow rate and the exhaust air flow rate, so that a negative pressure is not generated in the room in response to a change in the cross-sectional area of the heat exchange element 21. Control the fan to run. An air supply duct (or air supply pipe) 13 is provided between the air supply fan 12 and the heat exchanger 11 to supply the outside air to the room, and the air exchanger 11 and the exhaust fan 19 are disposed between the air supply fan 12 and the heat exchanger 11. An exhaust duct (or exhaust pipe) 18 for discharging air to the outside is installed.
    On the other hand, when looking at the functional unit installed in the room, the air supply duct (or air supply pipe 14) is provided with a plurality of air supply mechanism 15 for supplying clean air to each space in the room. In addition, a ventilation duct (or a ventilation pipe) 16 in which a plurality of ventilation holes 17 are formed to discharge air in each indoor space is installed. These air supply ducts 14 and the ventilation ducts 16 are respectively connected to the heat exchanger 11, which can be located in the air supply space 15 and the ventilation openings 17 in all the room to ventilate all the space in the room. Is extended so that. As such, the amount of ventilation for ventilation is automatically adjusted using the carbon dioxide sensor 22 installed in the indoor exhaust duct. Of course, this may be controlled manually.
    On the other hand, one side of the heat exchange element 21 in the heat exchanger 11 to prevent the noise generated by the air supply fan 12 or the exhaust fan 19 to be transmitted to the room, and the specific gravity is light to filter contaminants A sound absorbing filter 20 is provided. The sound absorbing filter 20 may not only be installed in the heat exchanger 11 but may be installed at any position in the ventilation system that may exert the same effect. In addition, the filter has a sound absorption function to prevent noise as well as a function for filtering contaminants such as dust and the like.
    Looking at the overall ventilation flow of the present invention having the structure as described above are as follows.
    First, the fresh air introduced by the air supply duct 13 and the air supply fan 12 directly connected to the air is supplied to the air supply duct 14 in the room through the heat exchanger 11. In addition, the indoor air warmed by heating in winter is discharged to the outside through the ventilation opening 17, the ventilation duct 16, the heat exchanger 11, the exhaust duct 18 and the exhaust fan 19 as much as the amount of outside air introduced. In the process of discharging, the heat energy in the air passing through the heat exchanger 11 is exchanged by the heat exchange element 21 inside the heat exchanger. That is, when the outside air passes through the heat exchanger 11 in the process of supplying air from the outside to the room as described above, the heat energy contained in the air discharged to the outside is transferred to the air introduced into the room, Allow it to be supplied to the room while it is warmed up. This heat exchange process can provide adequate ventilation to the room and prevent the loss of heating energy.
    In addition, the heat exchange element 21 absorbs moisture in the process of discharging the air inside the room, and provides moisture when the outdoor air having a relatively low humidity is supplied to the room, thereby making it easy to control the humidity in the room. .
    On the other hand, by installing a sound absorbing filter 20 having a light specific gravity, it minimizes the noise problem, which is the biggest problem that can occur when forced ventilation in a residential building, and the duct connected to the heat exchanger 11 has a flat structure and temperature, air flow distribution According to the variable design, it is possible to supply comfortable air not only in the living room but also throughout the living space such as the bedroom and the small room. For example, as shown in FIG. 4, the air supply fan 12 and the exhaust fan 19 are installed outdoors by using ducts on the walls of the multi-family house, and the heat exchanger 11, the air supply fan 12, and the exhaust air are installed. In separating and installing the fan 19, the heat exchanger 11 and the fans can be connected using a corrugated pipe or the like. Of course, in this case, passages for supply and exhaust are separately provided.
    6 is a structural diagram of a heat exchange element according to the present invention, in which 31 is an air supply side plate, 32 is an exhaust side plate, 33 is an air mixing prevention plate, 34 is a heat exchange element frame, and 35 is a filter mounting unit, respectively.
    As a material of the heat exchanger according to the present invention, a material having a high thermal conductivity such as an aluminum thin plate may be used, or a material such as a special processed paper of a moisture absorption and moisture absorption material may be used. Using such a material to form the corrugated plate (31, 32) in a concave-convex shape formed. And these corrugated boards 31 and 32 are laminated | stacked alternately so that an uneven shape may orthogonally cross. Here, the air mixing prevention plate 33 is laminated between the corrugated plate and the corrugated plate to prevent the air flowing between the uneven grooves from being mixed. Thus, a stack of corrugated sheets stacked so as to be orthogonal to each other is manufactured to produce a heat exchange element.
    In this structure, in order to further improve the heat exchange efficiency, the present invention uses the at least two or more diaphragms to form the uneven shape in the same direction, that is, in a matched form, in order to further improve the heat exchange efficiency. In this way, the air discharged to the outside has a wider interface than the air introduced into the room. Therefore, the thermal energy contained in the air discharged from the room to the outside can be reliably recovered.
    The plurality of corrugated plates formed in this way are installed in the frame 34, and a filter mounting part 35 for mounting a filter is installed at one side of the frame 34 in the air supply direction to form a flow such that air flows from the outside into the room. . In addition, the filter mounting part 35 is provided with a high efficiency dust collecting filter 20.
    As described above, in the present invention, in order to maximize the heat exchange efficiency between the air flowing into the room and the air discharged to the outside, the exhaust side is formed by stacking at least two or more corrugated plates to match each other, and the air supply side has only one corrugated plate. To form multiple stages.
    In the structure of the present invention, an unbalance of the air volume and a pressure difference between the indoor and the outside may be generated, so that the supply / exhaust fan is controlled at different speeds in order to prevent this. On the other hand, when driving the air supply fan and the exhaust fan through one drive motor size of the fan blades are different. In addition, the air supply / exhaust layer maximizes the heat transfer area and sets the gap gap and height so that the resistance of the heat exchange element itself is not large, and the wind speed and noise in the range to satisfy the ventilation required in the room. The cross-sectional area of the heat exchange element is determined from the condition that no discomfort will occur. In addition, to control the humidity in the room, it is preferable to use a material having a constant moisture absorption / dehumidification ability, such as a material containing a moisture absorbent or paper.
    In this structure of the present invention with reference to Figure 5 looks at the overall operation of the ventilation system.
    When the control switch 24 is turned on, the fan speed control unit 23 operates. The fan speed control unit 23 controls the air supply fan 12 and the exhaust fan 19 to operate at different speed ranges so that negative pressure does not occur in the room in response to a change in the cross-sectional area of the heat exchange element, thereby controlling the pressure difference between the indoor and outdoor. Try to solve the problem. On the other hand, when the supply fan and the exhaust fan are operated by one drive motor, the fan speed control unit 23 adjusts the fan speed only according to the concentration of carbon dioxide. In this case, the supply fan and the exhaust fan are driven by the same speed. It is controlled and the fan blade size is different to solve the pressure difference between indoor and outdoor. That is, since the amount of air discharged from the inside to the outside is greater than the amount of air flowing from the outside to the inside, the pressure difference between the indoor and outdoor can be solved by making the blade of the air supply fan larger than the blade of the exhaust fan.
    In addition, the fan speed control unit 23 is activated and at the same time the concentration of carbon dioxide in the room is sensed by the carbon dioxide sensor 22 installed in the ventilation duct 16, and the fan speed control unit 23 is a fan according to the detected concentration of carbon dioxide. It will control the operation speed of. The indoor carbon dioxide concentration is continuously measured while the system is operating, and the fan is stopped when the indoor carbon dioxide concentration is below a certain threshold. On the other hand, when the carbon dioxide concentration in the room is above a certain threshold, the fan is operated at the maximum speed.
    By this operation, when the carbon dioxide concentration in the room is lowered, the power of the fan required to continuously supply the conventional constant ventilation amount can be reduced, and when the person lives in the room, the necessary ventilation amount is continuously supplied to the human body. You can create a pleasant indoor environment.
    According to the present invention configured as described above can recover the heat energy lost during ventilation to save the winter heating energy and at the same time reduce the relative humidity difference between the indoor and outdoor, by using a duct, only a part of the indoor space of the current residential building In addition, it is possible to create a pleasant indoor air environment by supplying adequate ventilation throughout the living space of the occupants, and also to install the heat exchanger and the fan separately when it is difficult to install due to the problem of the installation space in the residential building. Not only can be used most appropriately for the balcony flat structure of domestic apartments, but because the fan is installed outdoors, it can solve the noise problem caused by the operation of the fan.
    In addition, by minimizing the power required to supply only the minimum required ventilation amount when the machine is running, it is possible to save energy according to the operation of the system as much as possible. It is possible to create a comfortable indoor environment by allowing the exhaust fans to operate at different speed ranges to solve the pressure difference outside the room.
