APPARATUS FOR MAXIMIZING AIR CONDITIONING AND/OR REFRIGERATION SYSTEM EFFICIENCY

摘要

The invention entails the use of a positive displacement pump (4) magnetically coupled to a drive motor (42) located in a conduit arrangement (60) this is parallel to the liquid line of the refrigeration system as in the figure. This parallel conduit arrangement also includes a pressure regulating valve that will regulate the amount of pressure added to the liquid line by the parallel pump and piping arrangement. In addition, a check valve (47) is located in the liquid line to maintain the pressure differential added to the liquid line. This parallel piping arrangement (60) is desirable in order to allow a constant, predetermined pressure to be added to the liquid line regardless of variations in flow rate of the liquid refrigerant. In addition, the parallel piping arrangement allows the system to operate without liquid line obstruction in the event of pump failure. Also a/any method of introducing a controlled, fine mist of water into the entering air stream of air cooled condensers to simulate the performance of an evaporative condenser by reducing the entering air temperature from dry bulb temperature to wet bulb temperature resulting in a reduction in system condensing temperature/pressure. The pump of the invention consists of an outer driving magnet (200), a stationary cup (201), and an O-ring seal (202). The pump further includes an inner driven magnet (203), a rotor assembly (204) and vanes (205). The pump further includes an O-ring seal (206) and a brass head (207).
