Summary

This publication is part of documentation on repair training software (FRIGODEP, FRIGODIAG and FRIGOLEC) for PC and PC-compatible computers, and is designed to teach repair procedures and to facilitate practice exercices using a computer. Summary: the pressure-temperature ratio (air condenser; direct-expansion evaporator; operating of the thermostatic expansion valve; influence of superheating on refrigerating capacity; influence of air temperature; thermostatic expansion valve; influence of pressure on mass flow and refrigerating capacity; influence of high pressure on the absorbed intensity; abnormally low pressure; air conditioning and commercial refrigeration); repair (expansion valve, evaporator, under-sized compressor or condensor; too little or too much charge; pre-expansion; uncondensable substances; checking for refrigerant leaks; problems encountered with fluid charge, flash gas in the liquid line and valve failure; interpretation of the uncondensables test); problems (migration of refrigerant fluid; short compression cycles; implementation and duration of the starting process in cold weather; oil return; the expansion valve power system; stopping of refrigerating compressors; capacity control; advice on repair procedures, etc.).
