Overview

Engineering reference data for Heat Recovery Ventilation (HRV/ERV) in HVAC systems.

Key Formulas

Sensible Heat

Q=m˙cpΔTQ = \dot{m} c_p \Delta T

Heat causing temperature change.

Latent Heat

Q=m˙hfgΔωQ = \dot{m} h_{fg} \Delta\omega

Heat causing moisture change.

COP (Cooling)

COP=Qc/WCOP = Q_c / W

Coefficient of performance.
