Electrostatic Regeneration of Refrigerant

The ubiquity of air conditioning and cooling systems, the ban on refrigerant release to the environment, and the high energy required by the refrigerant decomposition process give good opportunity for a novel technology to deliver a "like new" recycled refrigerant. In this paper we present several electrostatic processes at the heart of this technology: tribocharging the recovered mix of oil and refrigerant; the oil is removed by an electrostatic filter; a Faraday ring sensor monitors filter efficiency. A portable system prototype incorporating these technologies was built..
