HOT AIR HEATER

摘要

PROBLEM TO BE SOLVED: To discharge a low temperature circulation flow above an apparatus in addition to hot air discharged below the apparatus, thus to improve amenity by uniformalizing indoor distribution. SOLUTION: A part of an indoor air flow supplied from a blower 20 through a circulation flow opening 23 formed in the upper part of a duct 21 is discharged above a circulation flow outlet 24. By controlling closing of a moving louver 28 situated in a hot air outlet 27, a ratio between a flow of air discharged through the hot air outlet 27 and a flow of air fetched from a circulation flow opening 23 is freely regulated.
