It is recommended to install in bathroom, kitchen, balcony and other areas. The main considerations are as follows:
Whether there is enough space in the host installation area;
(2) Whether it is easy to maintain and avoid entering and leaving water pipes and wire pipes;
(3) When the new fan exhaust as far as possible away from the range hood (or exhaust fan, etc.) exhaust port, to avoid air cross pollution;
A safe distance should be kept between the inlet and outlet of the new fan. The recommended distance is not less than 3 times of the diameter of the pipe;
3. What effect will installing a new fan have on the height? How to solve?
F. After installation of equipment and pipes, the size and installation position of tuyere should be coordinated, and the loader should set tuyere well when finishing the suspended ceiling; The lower tuyere nozzle is flush with the ceiling and the side tuyere is flush with the wall. Install tuyere directly without cutting pipe orifice after installation. A portion of the hose may be retained at the end of the duct for later adjustment of the tuyere position.
G. After the overall decoration of the area, install the tuyere and control panel for equipment debugging.
2. Where is the new fan main machine installed? What should I pay attention to?
Het wordt aanbevolen om het te installeren in de badkamer, keuken, op het balkon en andere ruimtes. De belangrijkste overwegingen zijn als volgt:
Of er voldoende ruimte is in de installatiezone van de host;
(2) Of het gemakkelijk te onderhouden is en of men kan voorkomen dat waterleidingen en elektrische leidingen worden geraakt;
(3) When the new fan exhaust as far as possible away from the range hood (or exhaust fan, etc.) exhaust port, to avoid air cross pollution;
A safe distance should be kept between the inlet and outlet of the new fan. The recommended distance is not less than 3 times of the diameter of the pipe;
(5) After determining the location of the main engine, whether the layout of the entire pipeline is reasonable, whether a part of the branch pipeline is passing through long and other adverse conditions.
3. What effect will installing a new fan have on the height? How to solve?
(1) the machine selects the main pipeline static pressure box using parallel branches, in short, the original 160 main line can be converted into multiple 75 through branch pipes, and then all the way to 75 years per pipe in each area (above basic civil building beam wait 250,75 pipes can ensure safety leak beam).
The noise after installation mainly comes from three aspects: the sound of the machine running, the air volume of the air duct and the air volume of the air outlet. The latter two are mainly related to installation and operation.
Take 350, for example. When the main road is 160, the main wind speed is 4.84 m/s. When the main pipeline is selected to be 110, the main wind speed is 10.24m /s, which obviously exceeds the requirements of building ventilation design code. Compared with fresh air units, air conditioning units are more complicated in air handling. Therefore, air conditioning units are mostly used in large public areas where fAN-coil units cannot be installed, while fresh air units are mostly used in small areas where fan-coil units can be installed. Therefore, the best choice for a conventional pipe with a volume of 350 is the main pipe 160 and the branch pipe 110. If the height is high enough, the supervisor USES 200, which is better for resistance and noise control.
From a structural safety point of view, we should make sure that the diameter of the hole is less than one third of the thickness of the beam, that is to say, the beam is 250, more than 80 holes can be opened, we need to use a metal detector when drilling to avoid hitting the reinforcement. So what do we do when we actually come across a lintel?
It is recommended to send air to each room and return it centrally. Conditional also can send inside each room once, when this kind of circumstance, supply air and return air mouth adopt diagonal arrangement as far as possible, in order to avoid supply air short circuit.
Vanuit het oogpunt van structurele veiligheid moeten we ervoor zorgen dat de diameter van het gat minder dan een derde van de dikte van de draagbalk bedraagt; met andere woorden, als de draagbalk 250 mm dik is, kunnen er meer dan 80 gaten worden geboord. Bij het boren moet een metaaldetector worden gebruikt om te voorkomen dat de wapening wordt geraakt. Wat doen we dus wanneer we daadwerkelijk tegen een latei aanlopen?
(1) De machine selecteert de hoofdleiding met behulp van statische drukboxen en parallelle aftakkingen; kort gezegd kan de originele hoofdleiding van 160 mm worden omgezet in meerdere aftakkingen van 75 mm, waarna elk gebied via afzonderlijke leidingen van 75 mm wordt aangesloten (boven basisgebouwen met dragende balken van 250 mm kunnen leidingen van 75 mm de veiligheid van de balk garanderen).
(2) Zonder gebruik van aftakkingen is de leidingdiameter 160 — 110 — 75; wanneer de leiding door de draagbalk loopt, kan deze niet veilig worden geopend. Daarom kunt u kiezen voor Linde en een bepaalde hoeveelheid lucht opofferen om de veiligheid van het systeem te waarborgen.
5. What measures can be taken during installation to reduce noise during future use?
Het geluid na installatie komt voornamelijk van drie aspecten: het geluid van de werking van de machine, het luchtvolume in de luchtkanaal en het luchtvolume bij de luchtuitlaat. De laatste twee hebben vooral te maken met installatie en werking.
Take 350, for example. When the main road is 160, the main wind speed is 4.84 m/s. When the main pipeline is selected to be 110, the main wind speed is 10.24m /s, which obviously exceeds the requirements of building ventilation design code. Compared with fresh air units, air conditioning units are more complicated in air handling. Therefore, air conditioning units are mostly used in large public areas where fAN-coil units cannot be installed, while fresh air units are mostly used in small areas where fan-coil units can be installed. Therefore, the best choice for a conventional pipe with a volume of 350 is the main pipe 160 and the branch pipe 110. If the height is high enough, the supervisor USES 200, which is better for resistance and noise control.
The main cause of tuyere noise is improper selection of connecting hoses and tuyere. The hose connected at the end shall be secured with a tether to prevent the vibration sound caused by the supply air. A fresh air unit is an air conditioning unit that provides fresh air. The working principle is that the fresh air extracted from the outside is sent into the room by the fan after the treatment of dust removal, dehumidification (or humidification), cooling (or heating) and so on, and the original indoor air is replaced when entering the room.
6. How to avoid air loss caused by installation?
Any installation will cause some air loss, but some common mistakes should be avoided, such as choosing the right pipe diameter, replacing the 90-degree straight elbow with two 45-degree elbows, replacing the straight tee with a diagonal tee, and replacing the direct head with a gradient converter.
