Chiller Capacity Design Explained – ASHRAE 90.1 & SBC 601 | Step HVAC Calculation with Example

Learn how to calculate and select the right chiller capacity for any project using ASHRAE 90.1 and Saudi Building Code (SBC 601). This video covers load estimation, flow rate, ΔT, and tonnage calculations for residential, commercial, and hospital projects. We also walk through a complete real-world example using the formula TR = (GPM × ΔT) ÷ 24 in Revit MEP 3D visualization. Perfect for MEP engineers, designers, and students who want to master HVAC cooling load design and system optimization. 🧾 YouTube Description (Slide by Slide) ❄️ Slide 1 – Chiller System Overview Understand how chillers fit into the HVAC cooling loop with pumps, coils, and cooling towers. Learn design goals per ASHRAE 90.1 & SBC 601 to optimize efficiency and performance. Codes ensure proper selection, flow rate, and load balancing. 🏢 Slide 2 – Design Methods (TR/m²) Estimate cooling load per building type: • Residential: 0.10–0.15 TR/m² • Commercial: 0.15–0.20 TR/m² • Hospital: 0.20–0.28 TR/m² Higher TR/m² = higher heat gains due to occupancy and equipment. Use these as quick design references before detailed calculation. ⚙️ Slide 3 – Chiller Capacity Formula (ASHRAE 90.1) Formula: TR = (GPM × ΔT) ÷ 24 Where: GPM = chilled-water flow (gal/min) ΔT = temperature difference (°F) 24 = constant conversion factor This gives total cooling load in refrigeration tons (TR). 💧 Slide 4 – SBC Application & Efficiency Check Apply local SBC 601 guidelines: • Flow rate ≈ 2.4 GPM/TR • ΔT = 10–12 °F • Chiller efficiency ≥ 0.58 kW/TR Verify energy compliance and system sizing using these parameters. 🏠 Slide 5 – Real Project Example (Villa) Given: 900 GPM, ΔT = 10 °F Formula: TR = (900 × 10) ÷ 24 = 375 TR Select 400 TR chiller for safety margin. Result ensures optimal cooling and system reliability. #ChillerDesign #HVAC #ASHRAE901 #SBC601 #MEPDesign #RevitMEP #HVACCalculation #CoolingLoad #MechanicalEngineer #PlumbingDesign #Vision2030 #SaudiEngineering
