Abstract
—Recently, air tightness and thermal insulation performance of residential buildings have enhanced. However, that causes lack of ventilation. To improve indoor air quality, ventilation is important. In fact, natural ventilation in apartment buildings enhances indoor air quality but can lead to an increase of heating and cooling loads and cold draft. Maintaining both high-quality indoor air and pleasant heat conditions involves heating and air conditioning energy consumption. Under the circumstances, Energy Recovery Ventilation System (“ERVs”) is widely used to reduce energy consumption while maintaining good indoor air quality. The interest in ERVs has been increasing, but it has been lack of the efficient operating procedures for the systems. In this regard, this research offered two operating options (temperature-controlled and PMV controlled) of ERVs and A/C, established relevant ERVs operating algorithms, and performed optional operations. Additionally, indoor and outdoor temperatures and humidity, A/C and ERV’s operating status for each time zone, power consumption, and PMV (Predicted Mean Vote) values were measured to analyze the energy reduction effect depending on each control condition. As a result of the optional operation, higher air quality and more comfort of residents were achieved and energy consumption was reduced more in both optional operations compared to natural ventilation. If ERVs operating methods are adopted in apartment buildings by considering PMV and temperature changes, it will be useful to control the indoor environment in response to outside conditions and indoor load changes.
