중공사막 잠열교환소자 적용 환기시스템의 운전 및 에너지 성능에 대한 실험적 연구

Abstract

This study purposed to experimentally investigate the seasonal operating and energy performance of a hollow membrane latent heat exchanger-assisted ventilation unit. The proposed ventilation unit was fabricated, and the experiments was conducted based on the test standards for the energy recovery ventilator addressed from air-conditioning, heating and refrigeration institute (AHRI). In addition, the seasonal operation modes for the proposed ventilation unit were suggested . The measured data showed that the average sensible effectiveness, the average latent effectiveness, and the average enthalpy effectiveness of the proposed ventilation unit are 74.9%, 73.1%, and 76.1% in mode 1; 53.6%, 74.9%, 89.6% in mode 2; 80.6%, 68.1%, 78.1 % in mode 3. In addition, in case of energy performance, the proposed ventilation unit exhibited coefficient of energy (COE) of 31.5 in mode 1, 8.4 in mode 2, and 17.9 in mode 3, which satisfying the minimum requirement addressed in the energy recovery ventilator test standard in Korea.
