HVAC Visual Learning Studio
Read full descriptionHide full description
HVAC Visual Learning Studio is the engineering toolkit, refrigerant database, animated simulation lab, and visual reference library that working HVAC engineers actually use. This is NOT a generic learning template. Every screen — calculators, refrigerants, simulators, illustrations, projects — is specifically built around the daily work of HVAC design, troubleshooting, and controls. WHAT MAKES THIS APP DIFFERENT → HVAC ENGINEERING CALCULATORS (NEW in v3.0) Eight production-ready calculators with live sliders: - Sensible heat load (q = 1.08 × CFM × ΔT) - Latent heat load (q = 4840 × CFM × ΔW) - Mixed air temperature - Duct sizing (equal-friction method) - Pump friction head loss - Refrigerant superheat & subcooling diagnostic — with charge interpretation - Annual cost of operation from EER, tonnage, and electricity rate - Sensible Heat Ratio classifier Every input drives the result live. No spreadsheet required. → REFRIGERANT DATABASE (NEW in v3.0) Nine common refrigerants compared side-by-side: R-22, R-410A, R-134a, R-32, R-454B, R-1234yf, R-290 (propane), R-744 (CO₂), R-717 (ammonia). For each: ASHRAE 34 safety class, GWP, ODP, critical properties, typical operating pressures, applications, and engineering notes. Filter by family — HFC, HFO, blend, or natural. Tap any card for the full datasheet. → HVAC SIMULATION LAB Four animated simulators built specifically for HVAC: - AHU Simulator — airflow particles, spinning supply fan, modulating dampers, virtual zone thermostat - Refrigeration Cycle on a P-h diagram with live COP and EER - Psychrometric Chart with live state plotting and process lines - Chiller Plant with staging logic, cooling tower, animated water flow → ILLUSTRATED REFERENCE GALLERY 56 high-resolution HVAC diagrams across 11 categories: whole-house residential, multi-unit, commercial, industrial, ventilation, controls, documentation. Full-screen viewer with pinch-zoom. → CURRICULUM Six modules: HVAC Fundamentals, Psychrometrics, Refrigeration, Air Distribution, Hydronics, and Controls/DDC. Lessons include code examples, quizzes, and bookmarks. → DESIGN PROJECTS Six worked examples: residential Manual J, single-zone RTU sequences, VAV with reheat and pressure reset (ASHRAE Guideline 36), chiller plant design, school DOAS+ERV, heat-recovery VRF. → SEARCHABLE REFERENCE Psychrometric equations, refrigerant properties, ASHRAE standards summaries, BACnet object types — searchable by keyword. BUILT FOR - HVAC design engineers running daily calculations - Building automation and DDC professionals - Energy auditors and commissioning agents - HVAC technicians studying for NATE, EPA 608, or PE exams - Mechanical engineering students - Architects who want to actually understand the systems they spec WHAT'S NEW IN v3.0 - HVAC Calculators tab — 8 engineering calculators (new tab on the bottom bar) - Refrigerants tab — 9-refrigerant searchable database (new tab on the bottom bar) - What's New screen on first launch highlighting the new features - Updated illustrated gallery to 56 diagrams across 11 categories This app is an educational reference. Always verify with current ASHRAE standards, manufacturer data, and local codes before designing or installing equipment.
