Innovative Project

Project Description: Relocation of AHU to reduced ducting length and minimized solar heat losses.

Location: Node D37

Rational of the project: Existing unit were installed at roof of the “Node” with open to ambient

ducting length of 40 meter. The unit has been relocated under the ceiling with reduction in duct

length of 40 meter.

Also, have selected Plug fan over belt driven fan with EC motor over old EFF2 motor to enhance the

efficiency.

Capital Cost: INR 8.17 lakh

Annual savings: INR 1.7 lakh
