What new HVAC engineering calculator or refrigerant model should we build next?

[miadsaadidi]

We are planning the next wave of interactive, deterministic calculation tools for HVACLogic, and we want to build what the engineering and trade community needs most.

All HVACLogic solvers feature:

• 100% client-side computation (instant calculation with zero data tracking)
• Rigorous physics over static tabular approximations
• Mobile-responsive reactive visualizers

Current Proposed Ideas (Vote or Comment Below)

Here are a few candidate tools currently on our radar:

1. Low-GWP A2L Refrigerant PT & Glide Matrix
   • Dedicated temperature glide and subcooling/superheat diagnostic tool for R-454B and R-32 across evaporating and condensing ranges.
2. Heat Pump Low-Ambient Heating COP & Capacity Derate
   • Cold-climate inverter heat pump balance point calculator based on outdoor design temperatures and building envelope heat loss curves.
3. Hydronic Expansion Tank & Head Loss Solver
   • Closed-loop piping friction and diaphragm tank volume sizing with glycol mixture density and viscosity correction.
4. Kitchen / Commercial Hood Exhaust & Makeup Air (MUA)
   • Capture velocity and dedicated outdoor air CFM requirements under NFPA 96 and IMC guidelines.
5. Combustion Air Ventilation & Grille Free Area (NFPA 54)
   • Direct calculation of indoor/outdoor two-opening and horizontal duct combustion air sizing for gas appliances.
