Measurement on Energy Conservation of Heat Pump Air Conditioning System Employing Energy Recovery Ventilation in an Office Building

摘要

It is known that there are some methods of energy conservation for building facilities. Energy recovery ventilator (ERV),which can recover sensible heat and latent heat, is one of the solution to reduce heating/cooling loads, which are related to the power consumption of air conditioning systems. Manufactures specify the performance of ERV's effectiveness on the specification, however, there are few measured examples on energy effectiveness in actual conditions in mild climate area. Hence, measurements on energy reduction of heating system with ERV employed in an office building were executed with actual condition in winter season. From the measurement results, use of ERV reduced heat pump heating systems' energy consumption by approximately 30%. Heating load due to ventilation was reduced by 62%.
