Ventilation / Air Conditioning. Areas accessible to the public / drivers shall be equipped with sufficient air conditioning and ventilation. The system shall be designed to provide positive and uniform supply of fresh air in the parking and its exhaust through ducts/ fans. The ventilation system shall be designed to achieve minimum 15 air changes /hour in the parking areas during the normal operation and should achieve minimum 30 air changes/hour of exhaust in case of fire. Depending on the design of the Entry and Exit Areas, ventilation of emissions shall be required in that area.
Ventilation / Air Conditioning. Areas accessible to the public / drivers shall be equipped with sufficient air conditioning and ventilation. For manual/semi automate systems, where human presence in the storage areas is envisaged, adequate ventilation of vehicle emissions shall be provided. Basement shall have mechanical ventilation. The system shall be designed to provide positive and uniform supply of fresh air in the parking and its exhaust through ducts / fans. The ventilation system shall be designed to achieve minimum 15 air changes / hour in the parking / hours of exhaust in case of fire. The GI sheets for the sheet metal ductwork shall conform to IS- 227 and the ductwork shall be fabricated and executed strictly as per the requirements of IS-655. The Storage area of the System in which no drivers enter but only maintenance crews, may be unconditioned space, although ventilation of outside air shall be provided. No Ventilation of vehicle emissions is required inside the storage area. Depending on the design of the Entry and Exit Areas, ventilation of emissions shall be required in that area.
Ventilation / Air Conditioning. Services to be performed as part of scheduled preventative maintenance for ventilation/air conditioners is to include: Clean and inspect the filter area of the evaporator unit. Change filters. Wipe-out drip pan. Make sure condenser drains freely by running water down it. If it does not drain right away, clean out drain line. There shall be no standing water in the drip pan. Verify that air intakes are not blocked. Clean any visible debris. Ensure winter / summer functions are set and operating correctly using remote control. Inspect system for refrigerant leaks. Report to FAC if leak exists. Inspect fan belts (if equipped). Replace worn belts as needed. Return unit to service. Check indoor unit for: excess noise, proper cooling (discharge temperature must be able to run at lowest, normally 17 Celsius), all cycles should operate (e.g., fan only, dehumidification, and cooling). Record all the NEPA numbers in the log book. List all materials used in the log book. Clean-up work space.
