AIDC FM vs HVAC PT Chart Toolkit

AIDC FM is a field companion for data center facility operations teams. It brings local weather, engineering calculators, reference tables and an operations feed together in one app. WEATHER AND OPERATING MODE • Weather for your current location or any city you choose • Dry bulb, wet bulb and relative humidity • 24-hour trend and 7-day forecast • Suggests free cooling, precooling or mechanical cooling based on your own thresholds • Home-screen widget with the current wet bulb and suggested mode HVAC TOOLS • Psychrometric calculator • Cooling tower evaporation and blowdown • Refrigerant pressure–temperature lookup • Chilled-water load and air-cooled capacity • Plate heat exchanger efficiency and thermal storage discharge time • Pipe size, velocity and flow • Water quality diagnosis, and more ELECTRICAL TOOLS • Motor current and power • Power factor, apparent and reactive power • Voltage drop and three-phase short-circuit current • UPS and battery capacity sizing • Breaker settings and cable size selection, and more Every tool has a fixed code (for example H01 or E05), so you can find it by name or code. REFERENCE • Core HVAC temperature and pressure parameters • HVAC fault diagnosis and troubleshooting • Data center water quality reference values • Engineering unit conversion OPS FEED • Data center industry news and technical articles • Practical HVAC, electrical and facility operations know-how ACCOUNT (OPTIONAL) • Sign in with a one-time code sent to your email; no password, and your first sign-in creates the account • Your nickname syncs between your devices • Sign out or delete your account in the app at any time • Every tool, the weather and the Ops Feed work without an account Chinese and English interface, light and dark appearance. Entries in the Simple Password Notebook are encrypted in this device's Keychain and never uploaded. Calculation results are for operational analysis and engineering reference only. They do not replace manufacturer documentation, design documents or on-site safety procedures.

HVAC PT Chart Toolkit is an offline field workspace for technicians working on air conditioners, refrigeration systems, cold rooms, chillers and freezers. It is designed for paid, professional use: no account, no ads, no subscription and no server connection. Core tools: • Refrigerant PT charts for common refrigerants • Pressure to saturation temperature and temperature to pressure lookup • Superheat and subcooling calculators • Unit conversion for pressure, temperature, length, mass/charge, current/power, capacitance/resistance and vacuum/pressure • Offline fault code lookup • Symptom-based diagnostic checklists • Repair records, quotes, customer signatures and photos • PDF and image work order export • English and Simplified Chinese interface • Light, dark and system appearance modes Field workflow: 1. Search a refrigerant, fault code or tool 2. Calculate PT, superheat or subcooling 3. Follow a repair checklist 4. Add readings, photos, parts and labor 5. Capture a signature 6. Export a PDF or image repair order This app does not attempt to automatically diagnose equipment. Results are for field reference only and should be checked against the equipment nameplate, manufacturer documentation and actual site conditions. Electrical, high-pressure and flammable refrigerant work should be performed by qualified technicians following applicable safety rules. All data is stored locally on your device. Repair records are not uploaded. The app can be used in airplane mode.
