<p>PURPOSE: To realize a comfortable air-conditioning space by a method wherein radiation air-conditioning effect is obtained by utilizing a ceiling embedded type indoor machine for effecting convection type air conditioning. CONSTITUTION: In the normal heating operation mode of heating operation, outlet air from an indoor machine 1 flows toward a floor surface whereby an indoor temperature is risen quickly by convection. After the indoor temperature has been risen, the heating operation is shifted into radiation heating operation mode. In the radiation heating operation mode, outlet air from the indoor machine 1 flows horizontally substantially whereby warm-air zone is formed near the ceiling surface 5, further, the outlet air is heated to a high temperature to warm the ceiling surface 5 whereby radiation heating, utilizing radiation heat from the ceiling surface 5, is effected.</p> |
