Toxic chemical substances as Formaldehyde(HCHO) and Volatile Organic Compound(VOCs) came from high air-tightening for energy saving and indoor building materials has been causing a trouble such as making negative influenza to the resident's respiratory system or causing unbalanced human bodies. Therefore, it established new regulation of ventilator installation
standards that secures comfortable & safety Indoor Air Quality(IAQ) which discharges the indoor toxic chemical substances more quickly.
In this study, we will research to grope the efficiency enlargement plan by comparing & analyzing the efficiency that comes out from material differences of element core spacer.
The result of this study was as follows ; (1) Leak amount came out was 10% rate that correspond JIS research standard. (2) It is needed to decide the right spacer for element core by finding the best fit point in relation of efficiency and intensity dependent of spacer's CaCl2 content to design most suitable element core. (3) Pressure losses became increased during increments of passing airflow, and pressure loss got enlarged because the thick A-Type spacer made more smaller air gap which lets air thorough.
