HVAC System - Standard Operating Procedures

This clip explains in brief functioning of ‘heating, ventilation and air conditioning system’ in sequence.
In HVAC System, outside air is taken into the system from fresh air damper which passes through the pre-air-filter for filtration. The purified air then passes through the chilled water coil which cools the air to desired temperature. The chilled water and hot water coils constantly receives water from a chiller and boiler respectively. Now the cool air when, passes through hot water coil, loses its humidity and gets dried as desired by the user.
