The mechanical Ventilation systems are being considered to be designed for removal of heat and provide moderate dust free working environment. The systems are designed based on the adequate no. of air changes per hour however areas with higher heat dissipation could be considered for designing with restricted temperature rise over ambient temperature. Considering Varanasi Weather conditions we propose to install the evaporative cooling system to supply the fresh air to mechanical areas with greater heat dissipation like Pump Room and AC Plant Room.
