Description

Total Heat Exchanger {Heat Exchanger}

The present invention relates to a fan for ventilating indoor air to the outdoors. More particularly, it relates to a total heat exchanger that includes a total heat exchange element as one of the ventilation fans and can reduce heating and cooling losses by heat exchange of indoor and outdoor air.

In the total heat exchange element, a plurality of spacers are alternately arranged in layers in a direction intersecting with each other, forming flow paths in two intersecting directions. Total heat exchanger refers to a fan that exchanges heat between indoor and outdoor air by using such a total heat exchange element, and is a device that can increase heating and cooling efficiency than a normal fan.

1 is a plan view showing the internal structure of a conventional total heat exchanger. Referring to this, in the total heat exchanger (1), the total heat exchange element (3) is disposed at an angle in the housing (2) of the enclosure shape, so that the suction and discharge ports of the flow path are secured. And the partition walls 4 from the vertex of the total heat exchange element 3 to the inner wall of the housing 2 are respectively formed to have a structure in which outside air and bet are not mixed. Accordingly, the bet RA is sucked into the housing 2 by the blowing fan 5 and exhausted (EA) to the outside through the total heat exchange element 3 and the blowing fan 5 . And the outside air (OA) is sucked into the housing 2 by the blowing fan 5, and is supplied to the room through the total heat exchange element 3 and the blowing fan 5 (SA).

On the other hand, when the indoor/outdoor temperature difference is not large, a bypass mode in which the bet RA is directly exhausted EA without passing through the total heat exchange element 3 may be additionally implemented. The bypass mode may be configured by forming a hole in the bulkhead 4 and installing an electric damper that opens and closes the hole. Therefore, if only the exhaust (EA) side blower fan 5 is driven with the electric damper open, the bet RA can be directly exhausted EA without going through the total heat exchange element 3 . Patent Document 1 below also has the same structure.

However, such a structure in which the bulkhead 4 is formed or the electric damper is installed on the bulkhead 4 causes a problem in that the overall width W of the housing increases due to the width of the bulkhead 4, As a problem, there is a limitation in that the total heat exchanger can only be installed in a buried type in the ceiling or in a standing type on the indoor floor.

In addition, by installing the total heat exchanger on the wall of the building, one side of the total heat exchanger can be directly exposed to the outdoors, and there is an advantage in that the space for installing the total heat exchanger can be reduced. However, in this case, there is a problem in that dew condensation occurs in the total heat exchanger due to the temperature difference between indoor and outdoor in winter. And the dew condensation creates an environment for bacteria to easily inhabit in the total heat exchanger, causing a problem in the breakdown of electrical components such as motors.

9, the rear grill 170 is shown, the rear grill 170 is installed on the rear surface of the housing 20, is formed to introduce the outside air or exhaust the bet. The rear grill 170 is formed in a shallow box shape, and the grill body 171 is disposed to face the rear of the housing 20, and the grill wings 172 are formed extending downward from both sides of the grill body 171. includes In addition, the location of the inlet can be separated as shown in the drawing by using a partition 175 so that the introduced outdoor air and the exhausted bet are not mixed. In more detail, although the grill wings 172 are formed on the entire side in appearance, the exhaust hole 174 is formed on one upper side of FIG. The space in which the 174 and the outdoor air hole 173 are formed is blocked with a partition 175 so that the outdoor air and the exhaust are spatially separated and ventilated.

Therefore, according to the present invention, the upper portion of the rear grill 170 protrudes more than the lower portion as shown in FIG. interference can be avoided.

10 and 12 are longitudinal cross-sectional views of the present invention. With reference to this, the housing 20 and the internal installation configuration will be described in detail. The inner space of the housing 20 may be formed with an outdoor air room 210 into which outside air is introduced, a supply air room 220 through which outside air is discharged into the room, and an exhaust room 230 through which the bet air is discharged to the outside. The outdoor air room 210 and the supply air room 220 are disposed with the total heat exchange element 130 interposed therebetween, and the exhaust room 230 is disposed on the remaining edge side of the total heat exchange element 130 . On the other hand, in the housing 20 of the present invention, unlike the case of a general diameter, the space into which the bet is introduced is not secured or is formed in a very narrow space, which is the total heat exchange element 130 in the conventional total heat exchanger 10 in the housing 20. Compared to the diagonally formed one, the present invention provides total heat exchange with one surface of the housing 20 so that the bet directly flows into the total heat exchange element 130 while entering the housing 20 from the outside of the housing 20 without a separate space. This is because one surface of the element 130 is arranged side by side. Accordingly, the width of the total heat exchanger 10 can be remarkably reduced to be compactly formed.

In the outdoor air room 210, the outdoor air introduced into the outdoor air hole 173 enters through the outdoor air side damper 211 that can be opened and closed, and the outdoor air pre-filter 212 for filtering foreign substances or pests contained in the outdoor air can be installed. have. The air that has passed through the outdoor air pre-filter 212 may pass through the HEPA filter unit 140 , pass through the total heat exchange element 130 , and may be disposed to be introduced into the air supply room 220 .

The air supply motor 221 and the air supply fan 222 are installed in the air supply room 220 to suck air into the air supply room 220 . The air supply fan 222 may be a centrifugal fan, and the air is sucked in by the impeller, and the air flows and is discharged through the flow path formed outside the impeller. A fan flange 222a is formed at the discharge side end of the air supply fan 222 . The fan flange 222a is configured to install the air supply fan 222 to the fan installation panel 223 . The fan flange 222a has a structure that can be inserted along the fan installation rail 223a formed on the fan installation panel 223 as shown in the enlarged figure of FIG. 10 .

In addition, the air discharged from the air supply room 220 is supplied to the room through the silencer (225). The general total heat exchanger 10 has a structure that is discharged directly from the air supply room 220 to the outside of the housing 20 , but the present invention is configured to discharge from the air supply room 220 through the silencer 225 . In addition, the air discharge position of the air supply fan 222 and the position of the air supply grill 226 were set at a diagonal position so as to be far away from the silencer 225 so that the air flow path was passed through a sufficient length until air supply. This is a configuration for inducing interference by noise waves by changing the flow direction of air, whereby air can be supplied into the room through the hole formed in the air supply grill 226 in a state in which the noise amplitude is reduced.

Meanwhile, a panel installation rail 224 may be formed in the housing 20 so that the fan installation panel 223 may be installed. Referring back to the enlarged part of FIG. 10 , the panel installation rails 224 having a shape that can support both ends of the fan installation panel 223 are formed to extend along the width direction (based on the front surface) of the housing 20 , By inserting the fan installation panel 223 along the panel installation rail 224, the noise chamber 225 may be formed. In addition, additional insulation and noise materials can be attached to the fan installation panel 223 by inserting the fan installation panel 223 into the rail, so it can be installed with a simple configuration without additional components for noise and heat insulation, and noise reduction And it is possible to increase the thermal insulation efficiency.

In the exhaust room 230 , an exhaust side damper 231 opens and closes an outlet communicating with the exhaust hole 174 , a bypass damper 232 opens and closes between the outside air room 210 and the exhaust room 230 , and an impeller It may include an exhaust fan 234 including a, and an exhaust motor 233 for driving the exhaust fan 234 . The general total heat exchanger 10 is installed such that the direction of air discharged by the impeller matches the flow path direction of the total heat exchange element 130 , like the air supply fan 222 of the present invention. However, the exhaust fan 234 and the exhaust motor 233 of the present invention may be disposed to discharge air perpendicular to the flow path direction of the total heat exchange element 130 . That is, it is installed in a direction perpendicular to the air supply fan 222 and the air supply motor 221 as shown in the drawing. The space for motor installation can be greatly reduced by such an installation direction.

On the other hand, when the installation direction of the exhaust fan 234 and the exhaust motor 233 is taken as described above, the motor is completely in contact with the outdoor side, so that the structure is vulnerable to dew condensation. In order to compensate for this, the present invention has a thermal insulation structure that can protect the motor. Referring to FIG. 12 which is an enlarged view of part X of FIG. 10 , a circular rib 235 may protrude in a direction surrounding the exhaust motor 233 in a casing that surrounds the impeller and forms a flow path. In addition, by attaching a tape-shaped insulating material to the outside of the circular ribs 235, the interior of the space in which the exhaust motor 233 is formed can be sealed to form the sealed room 235a. By forming the heat insulating space in the sealed room 235a, it is possible to prevent a problem in that dew condensation occurs on the exhaust motor 233 side due to a temperature difference between the outside and the inside of the housing 20 . This is a characteristic technology that solves the problem of condensation that may occur as the window frame 20 type total heat exchanger 10 of the present invention is installed so that one surface is directly exposed to the outdoors, unlike the general total heat exchanger 10 .

In addition, FIG. 11 shows an enlarged configuration for detaching the total heat exchange element 130 and the HEPA filter unit 140 . Referring to this, the total heat exchange element 130 can be inserted from the indoor to the outdoor direction, which is in the same direction as the flow path formed inside the total heat exchange element 130 . For installation and disassembly, the element installation rib 132 may be formed to protrude into the housing 20 to guide and support the four corners formed in the upper and lower portions of the total heat exchange element 130 in the housing 20 for installation and disassembly. Therefore, the user can install and remove the total heat exchange element 130 by inserting it along the element installation rib 132 or pulling it out so that it can be conveniently replaced.

Similarly, a filter flange 143 is formed at the upper end of the filter case 141 of the HEPA filter unit 140 , and a filter rail 142 capable of supporting and guiding the filter flange 143 is installed inside the housing 20 . It may protrude from the wall surface, and may be formed to extend from an indoor to an outdoor direction. Accordingly, the user can easily insert and remove the filter case 141 by using the filter handle 144 formed on the front surface of the filter case 141 , and can replace the HEPA filter 145 in the removed state.

Meanwhile, it may further include an inner side damper 241 that opens and closes between the outdoor air room 210 and the lower grill 151 . The inner damper 241 is configured to introduce indoor air into the housing 20 without passing through the total heat exchange element 130 , and is configured to be opened during bypass mode operation.

In addition, first to third insulating rooms 123 may be formed in the housing 20 as an enclosed space. This is a configuration to compensate for the more vulnerable point to dew condensation as the total heat exchanger 10 of the present invention is installed to be directly exposed to the outdoors. The first insulating room 121 is formed on the outdoor wall of the air supply room 220 , the second insulating room 122 is formed on the outdoor wall where the exhaust fan 234 is installed, and the third insulating room 123 . is formed between the outside air room 210 and the control board on which the control boards formed under the housing 20 are formed. Here, the control unit may be formed to be physically partitioned from other parts in the housing 20 . Therefore, there is an effect of blocking the inside of the housing 20 from the outside by the first insulating room 121 and the second insulating room 122, and the part where the electrical equipment such as the board is installed is doubled through the third insulating room 123. It has the effect of preventing dew condensation more reliably by providing an insulated space. In addition, the insulating effect can be further maximized by inserting and inserting the insulating material into the first to third insulating rooms 123 .

13 to 15 show the air flow during operation in the normal mode, bypass mode, and air cleaning mode, respectively. The normal mode is a mode in which outdoor air and indoor air are ventilated through the total heat exchange element 130, the bypass mode is a mode in which indoor air is exhausted to the outdoors without passing through the total heat exchange element 130, and the air cleaning mode is indoor It is a mode in which air is supplied back into the room through the total heat exchange element 130 .

13, in the normal mode, outdoor air is introduced through the outdoor air hole 173 of the rear grill 170, and the outdoor air side damper 211, the outdoor air pre-filter 212, the HEPA filter 145, and the total heat exchange element ( 130), the air supply fan 222, the silencer 225, air is supplied to the room through the air supply grill 226. And the indoor air is introduced into the total heat exchange element 130 through the first inlet 161 on the side of the inner panel 160, the total heat exchange element 130, the exhaust fan 234, the exhaust side damper 231, It is exhausted to the outside through the exhaust hole 174 of the rear grill 170 . At this time, the outside damper 211 and the exhaust side damper 231 are opened, and the inside side damper 241 and the bypass damper 232 are operated to be closed.

14, in the bypass mode, indoor air is introduced into the housing 20 through the second inlet 162 and the lower grill 151 of the inner panel 160, the inner side damper 241, the outside air The pre-filter 212 , the bypass damper 232 , the exhaust fan 234 , the exhaust side damper 231 , and the exhaust hole 174 of the rear grill 170 are discharged to the outside. At this time, the inside damper 241, the bypass damper 232, and the exhaust side damper 231 are opened, and the outside air side damper 211 is operated to be closed.

15, in the air cleaning mode, indoor air is introduced into the housing 20 through the second inlet 162 and the lower grill 151 of the inner panel 160, the HEPA filter 145, and total heat exchange. Air is supplied into the room through the element 130 , the air supply fan 222 , the silencer 225 , and the air supply grill 226 . In addition, the indoor air may be purified and supplied through the HEPA filter 145 and the total heat exchange element 130 . At this time, the inner damper 241 is opened, and the outdoor damper 211 and the bypass damper 232 are operated to be closed.

According to the above-described configuration, the present invention has the following effects.

First, since one surface on which the flow path of the total heat exchange element 130 is formed is arranged in parallel with the one surface of the housing 20, a separate space for introducing the bet is not required, so the depth direction length of the total heat exchanger 10 (wall thickness) length corresponding to the length) can be significantly reduced. Therefore, the total heat exchanger 10 can be installed inside the wall.

Second, by providing an independent insulating space through the first to third insulating rooms 123 , it is possible to effectively compensate for dew condensation that may occur due to exposure to the outdoor side.

After the fan noise is reduced through the set material and the silencer 225 , air can be supplied to the room, and the silencer is attached to the fan installation panel 223 to provide a structure that can be easily assembled.

Fourth, by changing the installation directions of the exhaust motor 233 and the exhaust fan 234, it is possible to significantly reduce the depth direction length of the total heat exchanger 10 by compact installation. In addition, a circular rib 235 was added to form a closed room 235a in order to compensate for the problem of being vulnerable to dew by changing the installation direction.

Fifth, by the structure of the partition 175 of the rear grill 170 and the structure in which the directions of the outdoor air hole 173 and the exhaust hole 174 are different, there is an effect that the outdoor air and the exhaust are not mixed, and the rear grill is made compact. formed.

In the present specification, each detailed configuration has been described separately, but embodiments that can be derived by combining some configurations also fall within the scope of the present invention.
