It is an energy recovery ventilation system using equipment known as a heat recovery ventilator, heat exchanger, air exchanger, or air-to-air heat exchanger which employs a cross flow or counter-flow heat exchanger (countercurrent heat exchange) between the inbound and outbound air flow.Heat Recovery Ventilator provides fresh air and improved climate control, while also saving energy by reducing heating (and cooling) requirements for many applications including Green Buildings.
