Abstract
A micro-climate heating/cooling method and apparatus for vests and the like operates with reaction of working fluid, such as water, with an adsorbent material. A lightweight pump is the only moving component needed to provide the desired heating and cooling requirements.
Claims5
A heating/cooling system comprising a working fluid reservoir evaporator, a first heat exchanger operatively associated with the evaporator for cooling, an adsorption bed operatively connected with the evaporator to receive controlled amounts of working fluid vapor, a second heat exchanger operatively associated with the adsorption bed for heating, valves operatively associated with the first and second the exchangers for selectively cycling between the heating and cooling by the system, and, wherein a pump is operatively arranged with respect to the first and second heat exchangers to pump a second fluid thereto and therefrom to a location where one of heating and cooling is selectively desired and the location is a third heat exchanger arranged in a garment adapted to be worn by a person.
