A Research Into a New Method of Refrigeration Charging and the Effects of Improper Charging
MetadataShow full item record
The purpose of this report is to provide the results of research evaluating a new method of air conditioning charging and the effects of improper charging. The method is the visual accumulator-charger device. The report identifies seven presently known charging techniques and compares them to the method tested, as well as its accuracy of charging. A research on improper charging compared to the efficiency changes as a result of overcharge and undercharge conditions is the second part of the report. The visual accumulator-charger device proved to be a practical field charging technique for air conditioning systems and demonstrated an accuracy over a temperature range of 70°F to 100°F. It was also demonstrated that the improperly charged unit was dramatically affected.
