Details
The combined Air handling unit is a kind of equipment with multi-function air conditioning treatment. Its main functional sections include fan section, filter section, surface cooling section, humidification section, dehumidification section, heat recovery section, etc. So the unit assembled with so many functions is very large in size. It is generally a distribution assembly. It is assembled on site. Do you know the installation details of the combined Air handling unit during the installation process? Common sense of Air handling unit installation.
1. The combined Air handling unitshall be placed on a large mud boss with a height of 50-100mm. One side of the wall shall be left with a space of 1m. The boss plane shall be level and level. All functional sections shall be connected with bolts. The sections shall be sealed with foamed polyethylene to prevent air leakage.
2. After all the combined Air handling units have been installed, they shall be put into trial operation. They shall not be started under the condition of fully opening the air valve, so as to prevent the motor from being burnt out due to excessive starting current. The operation for 8 hours without abnormal phenomenon is qualified.
4. During installation, sealant (or other fillers) shall be applied to the joints of the framework to prevent air leakage.
5. The inlet and outlet pipes must be equipped with valves outside the unit to regulate the flow rate and cut off the cold (hot) water source during maintenance.
6. When the humidification section is selected for the combined Air handling unit, the inlet pipe of the humidification section shall be equipped with a valve and the inlet water pressure shall be basically constant.
7. The weight of air duct and water pipe connected with the unit shall not be borne by the unit.
8. Before installing each insulation wall plate, check whether the rotation direction of fan impeller is correct.
9. The combined Air handling unit is generally transported in sections, transported in pieces and assembled on site.
10. Before installation of the combined Air handling unit, the product specification and packing list shall be taken out for verification, and the integrity of all parts shall be checked. All parts shall be scrubbed clean, lubricated with grease, and the flexibility of rotating parts such as air valves and fans shall be checked.
11. Drainage ditches shall be reserved around the surface cooling section for the discharge of condensed water. The outlet of condensed water shall be provided with a water seal bend with a water seal height of 80-100 mm.
These are the details of the installation process of the combined air handling unit that often causes problems. During the installation process of the project, all departments need to strictly implement the installation standards to ensure the product installation specifications.
