Opening of AHU coil, supply duct & return duct , diffusers, grills, damper and any other installed component that part of the AC plant & duct of connected Area of Command Hospital (WC) Chm. All above part should be cleaned with following procedures and equipment :- Note : Cooling area will be taken for paymet purpose. (a) Vaccums collection : probably the most important component as this ensures that there is no cross contamination in plant premises. The units in use are equipped with a HEPA filter and high static fan. (b) Rotary brushes system self-propelled type with different types of brushes and used to agitate and loosen dirt with the duct. (c) Viper set used again to loosen dirt depending upon the type & size of duct. (d) Contact vacuuming method of HVAC system cleaning which incorporates agitation and vacuum collection principles into one operation. (e) Compressed air washing mechanical means to agitate and dislodge particulate from the interior surfaces of HVAC system. (f) Robotic camera used for inspection before, during and after the cleaning process. The video certified the duct clean and assist during cleaning. (g) All of the grill and differs are removed and cleaned. (h) Foam core boards are placed up to supply vent openings. The air movement holds these boards up to the openings, This also increases the air movement in the duct. All but one supply vent is covered. The open supply vent allows for the air to safety flow backward through the air duct system without creating adverse negative pressure.
