Testing for Energy Recovery Ventilators and Energy Saving Analysis with Air-Conditioning Systems

Energy recovery ventilators (ERVs) transfer energy between the air exhausted from building and the outdoor supply air to reduce the energy consumption associated with the conditioning of ventilation air. Higher ventilation rates improve the IAQ by diluting pollutants such as airborne particles and VOC. On the other hand, studies have shown that higher ventilation rates increase the building energy consumption in a majority of cases, especially during the hot summer season. Therefore, more energy is required to provide the space with more outdoor ventilation air and consequently better IAQ. The ERVs is important equipment for indoor air conditioning. The study results show that the ERVs can be energy saving and reduce indoor air pollution of modern buildings, improve indoor work and living environment. Testing for energy recovery ventilators and energy saving analysis with air-conditioning systems, the result can provide basic principle and referenced data for product improvement and air-conditioning system design.
