ABSTRACT:
Air cooled or heated by a localized air-temperature-modifying unit suspended from an air-retention shell is temporarily retained by the shell, thereby reducing the energy consumption and improving the efficiency of the air-temperature-modifying means. The preferred air-temperature-modifying means suspended from the shell is a chicken house brooder. The shell is generally conical, faces downwardly, and is made of a highly heat-retentive material, such as foamed synthetic resinous material.
