Technology Centre Systems Program – <strong>Draft</strong> DPR for New TC at Rohtak<br />

► Hybrid ventilation systems are popular in industrial buildings which predominantly use<br />

natural ventilation along with mechanically driven fans to improve predictability of<br />

performance over a wider range of weather conditions. Provisioning of the same will be taken<br />

into account wherever applicable during designing the ventilation system.<br />

b) Manufacturing/ Production area<br />

► Precision machining and QC areas will be provided with central air conditioning.<br />

► Air quality in production area will be checked for vital parameters such as concentration of<br />

CO2, CO and other relevant gases during operations.<br />

► In case the parameters above are not acceptable as per relevant standards, adequate<br />

capacity fresh air system will be designed and provided for production area to improve quality<br />

of air.<br />

► The fresh air supply system will consist of an external air handling unit of adequate capacity<br />

with suitable grade filters on inlet side.<br />

► The outlet of the air handling unit will be connected with duct system supplying air inside the<br />

production area at various places.<br />

► The fresh air will be discharged in the production area by providing suitable diffusers.<br />

c) UPS room<br />

► Appropriately designed ventilation system will be provided to the UPS room.<br />

► The ventilation system will mainly comprise of air conditioning units providing cold air at<br />

lower temperature and exhaust system taking out hot air coming out of the UPS.<br />

► The system will be designed to maintain adequate temperature around the UPS equipment<br />

as per manufacturer’s requirements/ specifications.<br />

► Humidity will be controlled to the desired level as directed by the UPS manufacturer by<br />

controlling inflow of fresh air.<br />

► Proper ventilation will be provided to battery racks with adequate number of air changes as<br />

per applicable rules and regulations.<br />
