| Research Abstract |
The effect of total heat exchanger on the decrease of ventilation load was examined in consideration of daily and annual change of outdoor temperature on each season. It was carried out through the field survey and the experiment chamber test. The influence of heat loss through the duct was evaluated and the amount of total heat recovery including that influence was 60 to 65 % of the amount of heat loss by non-heat exchange ventilation on the reference month of each season. The influence of the airflow from the inlet of the ventilator on indoor temperature and air distribution was also examined on each season. The windbreak plate attached to the inlet decreased thermal discomfort caused by the draft. It was also confirmed that the windbreak plate and the airflow from the indoor unit of air-conditioner gave the complex influence to the indoor environment on summer and winter period.
