Abstract
This invention relates to a system and apparatus for electronic control of an absorption refrigeration machine. The flow of liquids within the machine, as well as the concentration of the refrigerant/absorbent mixture solution are precisely controlled through the use of solenoid valves. These solenoids are controlled via a microprocessor control system with various sensors attached, which may include fluid level sensors, pressure sensors, temperature sensors and other environmental data sensors.
