Mega-sized shopping complexes or Hypermarkets tend to use central air supply system for the main tenant area and supplemented by fan coil units in localized areas. There would be a number of Pre-treated Air Handling Units (PAUs) and Air Handling Units (AHUs) on each floor. The size of the main air duct would usually start from 1,500mm (W) x 630mm (H) or above and gradually reduced to smaller dimensions such as 630mm (W) x 350mm (H) as branch air duct.Consequently, the recommended equipment for the cleaning of air ducts in these premises would be as follows:
- Main Air Duct
Initially utilize the Chaoyoda “Standard Automatic or Large Scale Automatic Cleaning Robot” to loosen the dirt accumulated on the duct walls and then use the “Four-in-One Modular Type Dust Absorption Robot” to extract all dirt settled on the bottom of the air duct by way of “Direct Dust Absorption Method”.
- Branch Air Duct
Use the Chaoyoda “Standard Automatic or Large Scale Automatic Cleaning Robot” in conjunction with the “i-Collect I ” by way of “Raised Dust Absorption Method” for good cleaning result.
