ZONEHVAC:ENERGYRECOVERYVENTILATOR

This compound component models a stand-alone energy recovery ventilator (ERV) that conditions outdoor ventilation air and supplies that air directly to a zone. The ERV unit is modeled as a collection of components: air-to-air heat exchanger, supply air fan, exhaust air fan and an optional controller to avoid overheating of the supply air (economizer or free cooling operation).
