As houses in cold climates are built tighter in terms of air leakage, Heat Recovery Ventilators have become required equipment so that fresh air is supplied to occupants.

[edit] Different shortcuts and types

I created just a discussion in the newsgroup alt.energy.renewable about correct translations of the German

"Lüftung mit Wärmerückgewinnung".

Common translations and shortcuts are

air to air heat exchanger heat recovery ventilator or HRV (heat recovery only) MHRV Mechanical Heat Recovery & Ventilation

When also the latent heat of the humidity is recovered, the name changes to

energy recovery ventilator or ERV (heat and humidity recovery)
