Equipment selection and duct design are iterative processes where the capacity of the equipment is balanced against the design of the distribution system. Selection of the equipment can have a substantial impact on the efficiency and operating costs of the system. Once the accurate estimation of the heating and cooling loads completed, the HVAC system designer will be able design / select the HVAC equipment as per the requirement.
HVAC Equipment Design course is customized as a strategy guide that describes the various equipment systems employed in HVAC applications and Selection of Equipment from manufacturers catalogue to meet the load demands in an HVAC System.
