09/05/2016 · There is an inverse relationship between air flow and temperature. For example, if the air flow over the element increases then one of two things happens: to maintain a constant temperature the element must increase its power output or the temperature of the output air will be lowered.

Combustion Efficiency and Excess Air

28/03/2018 · When air passes over a cold evaporator coil, two things happen. The air temperature drops (ΔT) and the concentration of water vapor in the air also drops (Δw) as the water vapor condenses on the coil. Both of those changes are part of the cooling capacity of a piece of equipment.

q = h (7.48 gal/ft3) / ( (1 Btu/lbmoF) (62.34 lb/ft3) (60 min/h) dt) = h / (500 dt) (2) where. q = water flow rate (gal/min) h = heat flow rate (Btu/h) ρ = density (lb/ft3) dt = temperature difference (oF) For more exact volumetric flow rates the properties of hot water should be used.
