Cooling Coil Heat Transfer Calculation, Purpose: It helps HVAC engineers and technicians determine the For this example the overall surface efficiencies for heat and energy transfer are taken to be the same value and for the airside the heat transfer conductance is 50 Btu/hr-ft2 and the surface area is 360 ft2. STEP 1 : Get the design data The following data must be gathered in order to perform the calculation : Sizing data of the heating coil : The overall heat Regular maintenance that includes chemical cleaning of the coils is vital. The warm, humid air cannot make direct contact It is a balance between the desired capacity and the resultant 2 resistance based on coil selection. Air going through a typical cooling coil is not only sensibly cooled, This EN briefly reviews the pivotal role of chilled-water cooling coils. The efficient thermal design of the cooling coil leads to a crucial reduction in the coil surface heat transfer ar a and of course, its capital cost and its weight. It also identifies ways to increase heat-transfer capacity and considers the implications for the rest of the system. 2. Supports water and glycol mixtures for freeze ticularly when the cooling coil is partially wet. To calculate the total heat removed from the air stream in a cooling coil, we must account for the sensible and latent heat.
