ABSTRACT:
A refrigeration system in which a compressed gas such as air is utilized in a rotary motor which enables the gas to expand for extracting heat by combining with or coming into contact with ambient atmosphere, air in an enclosure or articles, products or devices to be reduced in temperature. The rotary motor or expansion device is constructed in accordance with the well known structure of a Wankel engine except that the rotor of the motor is driven in relation to a stationary housing or casing by the introduction of compressed gas or air. The usually provided carburetor structure, intake manifold and ignition system are removed or modified with an inlet passage and exhaust passage being retained with the inlet passage being connected to a source of compressed air or gas through a control system and the outlet passage being communicated with atmosphere thus reducing the temperature of the expanded air or gas with the temperature reduction being up to 80.degree. F. to 90.degree. F. depending upon the operating conditions. The rotary motor is provided with an output shaft having a propeller mounted thereon to effectively control the speed of the motor for operation at highest efficiency.
