The main objective of the HVAC design calculations project is to provide correctly sized heating, ventilation and air conditioning systems for the building. 2 Heating circuits to the heater In design of heating system one can use either a system with constant flow and to regulate the heating power by temperature regulation or it can be done by using a variable flow system. 5.3.1 Overall Heat Transfer Coeﬃcient A heat exchanger analysis always begins with the determination of the overall heat transfer coeﬃcient. Typical heat and mass balance calculations do not de provi estimations of the physical size of the heater or even the ducting and other components such as combustion air fans, neither do they enable the calculation of system pressure losses or heat losses. AHeat exchange surface area (m 2). Heat exchanger design calculations. The calculation was based on heat transfer analysis of the fired heater taking into account heat absorption and losses in the radiant section of the heater.
