[0001] CEILING TYPE HEAT RECOVERY DEVICE BYPASS MODULE

[0002] Technical field of the invention

[0003] The invention relates to a bypass module that can be added to ceiling type heat recovery devices to enable the bypass damper feature to be used in desired situations without the need to produce a separate device.

[0004] State of the Art

[0005] Air conditioning devices are structures intended to transfer fresh air from the outside to the indoor environment, that is, to the air-conditioned environment, and / or to evacuate the air from the indoor environment. Heat exchangers are also used during said air circulation.

[0006] Utilising heat recovery systems while meeting the clean air needs of spaces is of great importance in terms of energy efficiency. However, when the temperature difference between indoor air and outdoor air is less than 3°C, heat recovery systems no longer have a function. In these cases, eliminating the increase in fan power that will occur due to pressure loss in the heat exchanger is aimed. To this end, dampers are used to bypass the heat exchanger and pass the air through a bypass line instead of the line where the heat exchanger is located. By means of this system, fan power, i.e. energy, is saved in conditions where heat recovery is not required.

[0007] Another function of dampers is to provide protection against frost that may occur in heat exchangers. If the outside air temperature is lower than -5°C, there is a risk of freezing on the heat recovery exchanger. When said temperature is observed in the external environment, the dampers direct the air to the bypass line, similar to the previous function. Dampers also work based on the principle that air prefers to flow in a path that does not cause pressure loss. In other words, if the bypass line is opened when necessary, the air is expected to pass through the bypass line instead of the line where the heat exchanger is located. On the other hand, outdoor and indoor temperatures get closer each other at times such as transition seasons, and morning and evening hours. In such cases, the heat recovery exchanger can be bypassed to eliminate heat exchanger pressure loss and use fresh air more efficiently. Similarly, if the outside air temperature drops below the indoor air temperature during seasonal transitions, the heat exchanger can be bypassed to cool the indoor environment by making use of the outdoor air. In similar cases, the bypass damper is opened, the heat recovery exchanger is disabled and the fresh air taken from the outside is transferred directly to the indoor environment. Control of the bypass damper is done by controlling the outdoor temperature, room temperature and set temperature.

[0008] The application numbered "TR 2006 / 00541” in the state of the art relates to heat recovery mechanisms comprising heat exchangers, fans, filters and air inlets. For the fans mentioned here, there is at least one hinge, a body containing at least one body part to form the modular structure, body connection edges and a cover. The aim of the invention is to fix the fan, which is one of the parts that make up the heat recovery mechanism, on the body with hinges and similar fasteners, thus making the fans have a modular structure and allowing only the fans to be dismantled instead of the complete device in case of fan failure. A new technology is needed in the heat recovery system that allows use both with and without a bypass damper.

[0009] The application numbered "CN107940925A” in the state of the art describes a modular combinable heat recovery type dehumidifying and drying machine. The machine comprises a circulating drying media channel, a circulating dehumidifying drying media channel, an expansion module circulating drying media channel, and an expansion module circulating dehumidifying drying media channel. This system comprises elements such as panel filter, bag filter, air volume control valve, condenser, battery, by-pass ventilation control valve and evaporator. The invention comprises a desiccant drying and a desiccant drying expansion module. A new technology is needed in which the heat recovery type dehumidifier and dryer can have options with and without a bypass damper.

[0010] Another disadvantage of the current system is the need to use a damper for each flow path. For this reason, not only the cost, but also the installation time increases. In addition to the aforementioned directing problem, another frequently experienced problem is that the dampers cannot fully seal when closed.

[0011] Additionally, the applications made on said devices are not of modular type. In cases where a bypass damper is required, the standard device is enlarged and the damper is added to the device. In this case, the bypass damper device series is also included along with the standard series. Thus, two different device types belonging to the same series emerge. In such applications, the sheet metals and internal structure of the device change when a bypass damper is desired or not. This situation also causes diversity. In cases where a bypass damper is desired or not, a new technology is needed in which the sheet metal and internal structure of the ceiling type heat recovery device do not change.

[0012] As a result, due to the negativities described above and the inadequacy of existing solutions on the subject, a new technology is needed in which the bypass damper feature can be used without any change in the sheet metal and internal structure of the ceiling type heat recovery device.

[0013] Brief Description and Aims of the Invention

[0014] The most important aim of the invention is to provide a ceiling type heat recovery device in which the bypass damper feature is made available by adding only a single module to the standard produced device, instead of producing two separate devices. By means of the modular type bypass damper used in the invention, instead of producing two separate devices with the same features, the bypass damper feature is made available by adding a module to the standard device. In this way, the situation of producing two different devices for an optional desired feature is eliminated.

[0015] Another aim of the invention is to have the body forming the heat recovery mechanism have a modular structure, thus ensuring ease of manufacturing and assembly. With the bypass module that can be added to existing devices, fresh air can be transferred directly to the room when desired. This ensures that fresh air is transferred to the room without passing through the heat recovery exchanger, in case the outdoor air temperature is suitable during transition periods (summer / winter intermediate seasons), that is, the device consumes less energy. Another aim of the invention is to ensure that repair and maintenance operations can be carried out easily. In order to achieve this aim, the invention has a modular structure.

[0016] Another aim of the invention is to enable a device previously produced without a bypass damper to be made with a bypass damper if necessary, by means of the module developed with the invention, a device shipped without a bypass damper can be converted to a bypass damper later by adding a module.

[0017] Another aim of the invention is to provide a bypass module with direction changing feature. The direction changing feature of said bypass module is used when it is desired to change the location of the duct connections of the device in the field (for example, relocation of the fresh air duct to exhaust air duct). There is no need to produce an additional device for such displacements.

[0054] Detailed Description of the Invention

[0055] The invention relates to a bypass module that can be added to ceiling type heat recovery devices to enable the bypass damper feature to be used in desired situations without the need to produce a separate device.

[0056] In addition to providing energy savings, ceiling type heat recovery devices designed to achieve high indoor air quality are produced as standard. By means of the system developed with the invention, when it is desired to use a bypass damper, instead of completely replacing the ceiling type heat recovery device, the top cover of the device is removed, and the bypass damper module is attached, and the top cover of the ceiling type heat recovery device is closed. Thus, instead of producing two different devices with and without a bypass damper, a standard device is produced. When a bypass damper is required, only the damper module is added. In this way, a device that was previously produced without a bypass damper can be made with a bypass damper if desired. In other words, a device shipped without a bypass damper can be made with a bypass damper later by adding a module.

[0057] In order to turn the ceiling type heat recovery device into one with a bypass damper, in the bypass module developed with the invention, first two bypass module body side sheet metals (1 ) and two bypass module body front-rear sheet metals are brought together as shown in Figure-1 . Afterwards, as can be seen in figure-2, the bypass module body side sheet metals (1 ) and bypass module body front-rear sheet metals

[0058] (2) are assembled with aluminium / steel rivets.

[0059] After the bypass module body side sheet metals (1 ) and bypass module body frontrear sheet metals (2) are assembled, two bypass module rear partition sheet metals

[0060] (3) and two bypass module front partition sheet metals (4) are fixed to the interior of this structure with aluminium / steel rivets. The assembled state of the bypass module body side sheet metals (1 ), bypass module body front-back sheet metals (2), bypass module rear partition sheet metals (3) and bypass module front partition sheet metals

[0061] (4) are shown in Figure-4. Afterwards, the heat exchanger stop sheet metals (14) that stop the bypass box are mounted with aluminium / steel rivets through the appropriate holes as shown in Figure-5. The view of the heat exchanger stop sheet metals (14), which are used to keep the bypass box firmly inside the bypass module, after being mounted with aluminium / steel rivets, is shown in Figure-6.

[0062] In the bypass damper module, the damper motor can also be connected to this part by using the damper motor connecting sheet metal (7). The damper motor connecting sheet metal (7) is mounted using appropriate screws to the places where there are rivet nut holes, as shown in Figure-7. The appearance of the mounted damper motor connecting sheet metal (7) is shown in Figure-8. The bypass damper box consisting of the bypass damper box sheet metal (9) and the bypass damper box cover sheet metal (10) shown in Figure-9 is placed inside this structure. After this stage, the damper shaft bushing and nut are mounted on the bypass damper box as shown in Figure-1 1 .

[0063] And after the damper shaft bushing and nut are mounted on the bypass damper box, the bypass damper flap assembly is placed as shown in Figure-13, between the bypass damper flap outer sheet metal (12) and the bypass damper flap support sheet metals (1 1 ) on which the bypass damper flap inner sheet metal (13) rests. After the placement, the detailed view of which is shown in Figure-14, the damper shaft and the damper motor shaft are mounted from places suitable for bypass flap mounting, using the damper shaft bushing and screw. After the mounting is completed, the bypass damper motor mounted on the damper fixing sheet metal (8) is positioned on the damper fixing sheet metal with a screw and rivet nut hole. Finally, after the bypass damper motor is mounted on the module developed with the invention, its appearance is as shown in Figure-19.

[0064] Since the device developed with the invention is symmetrical and suitable for direction change in the field, this feature is provided by turning the bypass module when the direction of the device is desired, by means of the modular bypass damper. The bypass damper module is designed to accommodate direction changes in order not to disrupt the symmetry provided by the standard device. To change direction, the bypass damper motor is first demounted by removing the screws from the part where it is mounted. After the bypass damper motor is removed, the bypass damper flap is removed by removing the damper motor shaft and damper shaft fixing screws from the bypass damper flap. After this stage, the damper shaft bushing and nut in the bypass damper box are removed and the bypass damper box is removed. After the direction change is made, it is fixed in its current position. Afterwards, the damper shaft bushing and nut are attached on the bypass damper box. Then, the bypass damper flap is passed through the bypass damper blade support sheet metals (1 1 ) and the damper motor shaft and damper shaft are mounted to the appropriate places on the damper blade. Then, the bypass damper motor is mounted back to the module with a screw. By means of the module developed with the invention, the direction of the bypass damper module can be changed using a single device instead of using many devices with different directions. By means of this structure, a ceiling type heat recovery device that can be used in different directions, with or without bypass damper, can be obtained.

[0065] Figure-18, added for a clearer understanding of the structure developed with the invention, shows the bypass module right cover sheet metal (5) and the bypass module left cover sheet metal (6), which are used to close the bypass module after it is positioned. In addition, in order to prevent possible air leaks, a polyurethane gasket has been applied to all surfaces of bypass module body side sheet metals (1 ), bypass module body front-rear sheet metals (2), bypass module rear partition sheet metals (3), bypass module front partition sheet metals (4), the bypass module right cover sheet metal (5) and the bypass module left cover sheet metal (6) that come into contact with the device. In addition to the mentioned elements, polyurethane gaskets have been applied to the surfaces in contact with the bypass damper flap support sheet metal (1 1 ), bypass damper flap outer sheet metal (12) and bypass damper flap inner sheet metal (13) in order to prevent leaks.

[0066] The bypass damper module can be easily placed when using a bypass damper in a ceiling type heat recovery device. When the user wants to use a bypass damper in the ceiling type heat recovery device, the cover of the ceiling type heat recovery device is removed, and the bypass damper module developed with the invention is added. After this addition, the upper surface of the ceiling type heat recovery device and the lower surface of the ceiling type heat recovery device cover come into contact with the bypass damper module. After this contact is made, the top cover is closed and it continues to operate with a bypass damper like a standard device. A device shipped without a bypass damper can be turned into one with a bypass damper later by adding a module. In addition, when the use of bypass damper in the ceiling type heat recovery device is not desired, the cover of the ceiling type heat recovery device is removed in the same way and the bypass damper module developed with the invention is removed. Afterwards, the ceiling type heat recovery device can continue to operate without bypass damper. In this way, operation without bypass damper and with bypass damper can be achieved using a single device.
