Delta T (ΔT) in HVAC Systems – Complete Explanation In HVAC, Delta T (ΔT) means: Difference between two temperatures Formula: ΔT=T1−T2 Where: ΔT = Temperature difference T₁ = First temperature T₂ = Second temperature Why Delta T is Important in HVAC Delta T tells us: • How much cooling or heating is happening • Whether equipment is working properly • Energy efficiency of system • Water flow and air flow condition • Coil performance • Chiller efficiency In HVAC mainly two Delta T are used: • Water Side Delta T • Air Side Delta T 1. Water Side Delta T (Chilled Water / Hot Water) This is the temperature difference between: • Supply water temperature • Return water temperature Usually used in: • Chillers • FCU • AHU • Heat exchangers Chilled Water Delta T In cooling system: • Chiller sends cold water → called CHWS (Chilled Water Supply) • Water absorbs room heat • Warm water returns → called CHWR (Chilled Water Return) Formula: ΔTwater = Treturn−Tsupply Example 1 – Normal ...
