Abstract: The Energy Recovery Ventilator (ERV) is an important equipment for indoor air conditioning; where outdoor fresh air is pre-cooled when passing through the heat reclamation equipment in summer. The building energy-consuming simulation software eQUEST is used to analyze the load change of a building in Xiamen. For the commercial building of 6912m², the air-conditioning system with ERV has an electric power saving of 13298 kW·h in July and 12927 kW·h in August, and then about 8205 Yuan can be saved in July and 7976 Yuan can be saved in August. When ERV fan power consumption is considered, the electric power saving is 3680 kW·h in July and 3312 kW·h in August. Comprehensive comparison shows that, installation of ERV for an air conditioning system is more economical by recovering additional cooling energy.
