65 Heat Recovery Ventilator (HRV) A heat recovery ventilator (HRV) is a type of air-to-air heat exchanger that transfers heat between incoming and outgoing streams of air. A HRV dramatically reduces heat losses from mechanical ventilation with efficiencies ranging from 70% to 85% . An energy recovery ventilator (ERV) is a specific type of HRV that exchanges heat and moisture between air streams (sensible and latent portion). The energy or heat recovery may occur at the space level (unit ventilators) or at building level in an air handling unit using enthalpy wheel or heat exchanger.
