Страница 18: ... Analysis of Trouble Low efficiency of a refrigerating compressor refers to the actual reduction of gas discharge capacity and hence the corresponding reduction of refrigerating capacity under the condition that the refrigerant in the system is unchanged This phenomenon occurs mostly when the compressor has been used for quite a long time its moving parts have worn to a considerable degree fit cle...

Страница 19: ... in refrigerating system Analysis of Trouble Because the refrigerating system was originally not purged thoroughly some of the filter screen meshes have been clogged by dirt accumulated in the filter after using it for a certain time of period thus resulting in a decrease in flow rate and hence a poorer refrigerating effect The abnormal phenomena caused by this kind of slight clogging in the syste...
