The Sensible Heat Formula: Q = C x M x ∆𝑇 Q= quantity of sensible heat in BTU/hr M= mass C= specific heat of material ∆𝑇= temp difference Applied to Standard Air Applied to Water (not glycol)
Equations 41 VT = Volume of Expansion Tank (Gallons) VS = Volume of Water in Piping System (Gallons) ∆T = T2 − T1 (°F) T1 = Lower System Temperature (°F) Heating Water T 1 = 45–50°F Temperature at Fill Condi- tion Chilled Water T 1 = Supply Water Temperature Dual Temperature T1 = Chilled Water Supply Temperature T2 = Higher System Temperature (°F) Heating Water T 2 = Supply Water ...
Latent Heat: LH = 3.0 Q∆w. where heat is in W = ∆t temperature difference, K or °C = ∆h enthalpy difference, kJ/kg ∆w = moisture concentration, g/kg dry air = Q flow rate of air, L/s. Pump or Fan Power. P = Q h.
HVACR FORMULAS. TON OF REFRIGERATION - The amount of heat required to melt a ton (2000 lbs.) of ice at 32°F 288,000 BTU/24 hr. 12,000 BTU/hr. APPROXIMATELY 2 inches Hg. (mercury) = 1 psi.
ENTHALPHY = Sensible heat and Latent heat TOTAL HEAT FORMULA (for cooling, humidifying or dehumidifying) BTU/hr. = Specific Density X 60 min./hr. X CFM X ∆ H = 0.75 x 60 x CFM x ∆ H = 4.5 x CFM x ∆ H RELATIVE HUMIDITY = __Moisture present___ Moisture air can hold SPECIFIC HUMIDITY = grains of moisture per dry air 7000 GRAINS in 1 lb. of ...
