20100070090HEATING AND COOLING SYSTEM USING COMPRESSED FLUID - Use of compressed air for indoor ambient temperature conditioning is disclosed. Thermal energy is imparted to or extracted from a quantity of compressed air, and the compressed air is then directed to be released inside a structure enclosing a space, whose ambient temperature needs to be controlled. Thus, the compressed air may be used as a direct heat conduction/extraction medium. A flow of external air is created over a heat exchanger mass (a “heating mass” or a “cooling mass”), so that thermal energy of the compressed air flowing inside the heat exchanger mass is transferred to the external flow of air flowing outside the heat exchanger mass. Thus, in addition to being a direct heat conduction/extraction medium, the compressed air is being used as a heat transfer medium, that ultimately gets mixed with the flow of external air. A fresh supply of external air may be used rather than using re-circulated air, in order to maintain a high quality of breathable air. A local feedback loop may be used to route back a portion of temperature-conditioned air produced by a system according to the present invention, to regulate a flow of external air over a heat exchanger mass. Other types of environmentally benign compressible fluids may be used as a heat transport/transfer fluid instead of compressed air.03-18-2010
