Air-to-air heat recovery ventilator widely used in high-rise apartments in Korea has relatively short history and is not operated by experts of HVAC system. Therefore, survey and field measurement of air flow rate were performed, since the investigation about effective use of HRV system is required in this circumstance. Most respondents of the survey replied that daily operation time was six hours per day operation mode was medium. Regarding the feeling of satisfaction, the value was 3.931 in evaluation scale 1~6, indicating that they are relatively satisfied with HRV system. Moreover, the result of measured air flow rate was a little lower than that of recommended air flow rate, and mean air exchange rate appeared to be 0.38ACH. |
