<p>A basic air conditioning/refrigeration system charge (filled) with, typically nitrogen gas mix six to ten atmospheres with a specific heat of gas equal to 0.222 B.T.U. per degree F change per cubic foot per atmosphere when in operation. The system may be run so the gas circulates through the system at 15.5 A.C.F.M. yielding a shaft output of one horse power out of a cooling gas expansion motor. The gas expansion motor, that may be a multi-cylinder-piston wobble plate motor, has a feed and exhaust valve feeding passageway and cylinder space at piston top dead center with a volumetric ratio of one to a figure in the range of seven to twelve, and even on to twenty four times at the bottom of the individual piston stroke.</p> |
