Air-Conditioning psychrometric cooling & dehumidification process is a complex thing. Plotting psychrometric chart has never been an easy task for design engineers. Not anymore! with aPsychroAC, you can do various calculations and plot psychro chart in a few clicks at anytime, anywhere...

Complex calculation software can be difficult to understand and use. aPsychroAC is intentionally designed not to be complex, but rather simple, practical, easy to understand and use. The main objective of engineering this software is to help HVAC designers in providing quick design solutions for the following air-conditioning design applications:

- Summer conditions (not for Winter conditions)
- Cooling & dehumidification process (not for system with humidifier, etc).

OA inputs accept Conditioned Air (CA) conditions such as treated outdoor air from Precool Coil / Precool Air Unit (PAU), Heat Recovery Wheel (HRW), Run-Around Coil (RAC), Heat Pipe (HP), etc.

PAU, HRW, RAC and HP calculations are included as separate modules with "Export CA" feature. The calculated SA (CA) conditions can be fed (exported) to the main AHU module as precooled (treated) outdoor air. You can recall back the PAU, HRW, RAC or HP module with its current activity's state retained.

Built-in standalone modules:
- Precool Coil / Precool Air Unit (PAU) module
- Heat Recovery Wheel (HRW) module
- Heat Pipe (HP) module
- Run-Around Coil (RAC) module
- Air Mixing psychrometric module
- rhoAIR module

Highlights:
- Carrier ESHF (Effective Sensible Heat Factor) method or Supply Air Temperature method
- Recirculating or 100% OA (for SA Temperature method only) system
- Reheat option
- Fan heat gain option (draw-thru arrangement only)
- Plot & save psychrometric chart
- Built-in guides and explanations
- in SI-IP Units

No more manual plotting of psychro chart. With aPsychroAC, psychro chart showing the air-conditioning process is automatically plotted for each calculation.
