Abstract

An electrically powered heater/cooler is coupled to a pair of air heat exchangers to warm one above ambient temperature and to cool the other below ambient. Input ducts to the heat exchangers are connected to a common duct attached to a fan supplying ambient air to both heat exchangers. The warm and cool air output ducts from the heat exchangers are connected to input ducts on opposing sides of a plenum which includes exit ducting on opposing sides. A vane assembly is movably supported within the plenum and is positioned to control the access of the cool and warm sides to the output ducts from the plenum. One output duct from the plenum connects a comfort conditioning air stream to ducting connected to a distributor mounted to direct the stream to the head and neck regioins of an indivudual. The other output duct connects rejected air to the ambient environment.

Claims1

Dependent claims

A personal comfort conditioner system for heating or cooling a single individual comprising:

(a) a frame;
(b) a fan assembly connected to said frame;
(c) an ambient air heat exchanger assembly having separate heating and cooling chambers supported by said frame;
(d) an air input ducting assembly interconnecting said fan assembly with both of said chambers to provide ambient room air to both of said chambers;
(e) an electrically powered thermoelectric heat pump assembly attached to said chambers for simultaneously separately heating and cooling room air in said chambers;
(f) a plenum connected at opposite sides to said chambers for receiving flow of heated and cooled room air therefrom;
(g) a single movable baffle disposed in said plenum between said flow of heated and cooled air to proportion the relative magnitudes of said flows;
(h) a comfort conditioning distributor having means for directing conditioned air to a single individual;
and
(i) a first output ducting assembly interconnecting said plenum at one side of said baffle to said air distributor, and a second output ducting assembly interconnecting said plenum at the opposite side of said baffle to the room ambient remotely from the individual.
