<P>PROBLEM TO BE SOLVED: To provide an indoor cooling and heating method for cooling or heating a room by easily elevating or descending an air reflux unit installed in the room for any purpose. <P>SOLUTION: When a room is heated in winter and cooled in summer, warm and cool air regions are naturally separated by the difference in the specific gravity induced by the temperature difference generating in a room for the energy saving purpose. An air reflux unit is easily elevated or descended and positioned by selecting the warm air region and the cool air region in winter and summer, respectively, for power saving. Thus, the air reflux unit is used both for heating and cooling for any purpose. During cooling, warm air near the ceiling is kept as it is, while cool air is circulated only in a lower cooling zone which is a human action range. <P>COPYRIGHT: (C)2012,JPO&INPIT |
