Frequently asked questions

Q: You're checking a VAV reheat box during commissioning and search for "calculate HVAC reheat energy from airflow and delta T". The box delivers 1,200 m3/h of air, reheated from 14°C to 22°C. Assume air density 1.2 kg/m3 and cp = 1.02 kJ/kg·K. What is the reheat load?

A: Oversizing here drives chronic valve hunting and higher boiler cycling. The sensible load comes straight from m·cp·ΔT: 1,200/3,600 × 1.2 × 1.02 × 8, which lands near 3.3 kW. That keeps the reheat coil and control valve sized in a stable range instead of masking poor airside control with excess capacity.

Q: A plant engineer searches "what does HVAC free cooling economizer not protect against" after a freeze trip. In an airside economizer with low-limit temperature cutout failed, what is the most likely physical consequence?

A: Acting on the wrong assumption here ends with split coils and glycol spills. Without the low-limit safeguard, cold air keeps flowing across a wet coil at low load, dropping film temperature below freezing. Recognizing that risk is why freeze stats and bypass dampers exist, not to manage pressure or compressor behavior.

Q: During a walkdown, you google "rule of thumb HVAC fan energy per airflow". A supply fan moves 20,000 m3/h with a measured total pressure rise of 800 Pa and overall efficiency near 60%. What's a defensible order-of-magnitude motor power?

A: Underestimating this pushes you toward undersized VFDs and nuisance trips at SAT. Power follows Q·ΔP/η: 20,000/3,600 × 800 / 0.6 gives a result in the high single‑digit kW range. That sanity check keeps electrical and cooling loads aligned before detailed selection.

Q: Your lead asks you to confirm "how to calculate chiller COP from kW and tons". A water-cooled chiller produces 500 kW of cooling while drawing 100 kW electrical at steady state. What COP should be reported?

A: Reporting the wrong COP mislabels an efficient machine as a poor performer and derails M&V. COP is a simple ratio of cooling effect to electrical input in consistent units, so 500 divided by 100. That preserves comparability with ASHRAE benchmarks without unit gymnastics.
