The purpose of this study is to evaluate the performance of wall type ventilation systems heat exchange unit adapted. Performance of ventilation systems was estimated by a ventilation rate, ventilation effectiveness and power consumption. Experiment was performed in a thermal environmental chamber that heated by a electric heating cable. A tracer gas technique was used to measure ventilation effectiveness of ventilation systems. A tracer gas of CO₂ was injected in a chamber using step-up method. The results of this study can be summarized as follows. (1) The air infiltration rate of the chamber was calculated by 0.5 ACH. (2) Effective ventilation rate of each ventilation system was estimated by 60 percent of a ventilation airflow rate. (3) The ventilation effectiveness of ventilation systems was measured by 70 percent. (4) Energy saving rate of a heat recovery wall type ventilation system was improved 28 compared to general wall type ventilation system.
