초록

Packaged terminal heat pump systems, which are mainly used in small- and medium-sized buildings, are known to be cost-effective and thermally comfortable heating and cooling equipment. However, in practice, the issues of inefficient energy use as well as thermal discomfort have been discussed. Simplified design and application processes of packaged terminal heat pump systems can cause occupant thermal discomfort. In this study, the actual characteristics of occupant thermal comfort related to draft were analyzed during the operation of packaged terminal heat pump systems. Indoor thermal environment was evaluated by an Effective Draft Temperature(EDT) equation. The result shows that thermal discomfort occurred since 4-way type heat pump system is applied without careful consideration of the air temperature, velocity and indoor air distribution.
