How the calculation works +
Four rack zones use sensible heat balance and an assumed recirculation fraction. The mixing rise is r/(1-r) × rack temperature rise. Capacity and COP follow explicitly assumed outdoor-temperature curves. The transient combines a 40-second mixing response with a 6 MJ/K effective hall heat capacity. Zone colors show calculated zone averages.
The temperature comparison uses the ASHRAE A1-A4 recommended dry-bulb inlet range of 18-27°C.
