Method for extending duration of use of refrigerant and improving cooling efficiency using microcomputer circuitry and logic

A method for reducing the amount and volume of cooled refrigerant that is generally necessary for cooling air for chilled air output adapted for intermittent usage and further optimizing and extending the duration of cooling functionality by deactivating the unit during the periods when cooling is not needed thus conserving the rate of expending pre-cooled refrigerant provided for cooling of air, the method comprising the steps of:

• providing a portable air cooling system for cooling and directing of cooled air, generally for mobile use by a user including use in golf carts, the system comprising in combination an insulated portable casing, an air cooling assembly comprising refrigerant packs, air blower fans, a portable power source, at least one of the air blower fans providing circulation of external air through the insulated portable casing and around and between the refrigerant packs and further directing the cooled air flow in a direction selected by the user, the refrigerated/cooled refrigerant packs providing cooling of the external air, and a computer control unit, wherein the processor and programmer of the computer control unit providing regulation of the speed of the blower fans and further providing optimization of the efficiency of cooling function of the portable air cooling system;
• providing microcomputer circuitry and logic for generating data format for the operational functions including signaling and activating the portable air cooling unit (30), including the blower fans, providing chilled air output upon the electronic sensors operably coupled with the microcomputer circuitry and logic continue sensing and locating the predefined object including an individual positioned within a predefined space range and the logic further generating signals, switching off and deactivating the blower fans and thus the output of chilled air upon the electronic sensors sensing no specific predefined object being positioned within the predefined range, the data format associates with the predefined object including the data format associated with the aspect of the individual located within the predefined space;
• installing and storing in the memory of the microcomputer programs and data format including, data format associated with specific predefined object, data format associated with the dimensional aspect of the specific predefined range and programs and data format in part providing processing of signals and generating specific data format for triggering and executing specific functions associated with the portable air cooling system;
• and
• operably coupling the electronic sensors including proximity sensors with the microcomputer circuitry and logic, providing sensing and data format associated with the predefined positional aspect of the object including the data format of the location aspect of the individual positioned within a predefined range, the microcomputer circuitry and logic upon sensing and locating the signal associated with the individual to be within the predefined range generating signals regulating switching and maintaining activation of the cooling operations of the portable air cooling units (30) for the duration the predefined object is positioned within the predefined range, further including switching off of the portable air cooling unit and deactivating cooling operations upon the logic not sensing the positional data format aspect of the object being positioned not within the predefined range, further the air cooler system being reactivated by an individual encroaching within the predefined range.
