Analysis of Troubles and Troubleshooting

Maintenance Service and Trouble Shooting

ambient temperature ,this means that most meshes of its screen has been clogged ,resulting in an obstructed flowing of refrigerant ,thus causing a drop in temperature due to throttling .

d)Feel the temperature of exhaust gas from the refrigerating system .the exhaust gas should be very hot and this is the normal working state .For those refrigerator with enclosed type of compressor refrigerating

system, no frost or dew drop will from on the gas suction tube ,otherwise ,there is something wrong in the system (Frosting and dew condensation may appear for a very short time period when just starting the machine ,this is a normal phenomenon ).

Because a refrigerator is a combination of several components ,they are related and have influence on each other .In case an abnormal phenomenon has been found through the above-mentioned checkups ,you need not to make a hasty conclusion based on only one abnormal phenomenon .It is advisable to find out two or more abnormal phenomenon ,or conduct troubleshooting comprehensively with the aid of instruments or other ways ,because several kinds of troubles may share a common abnormal phenomenon ,and two or more abnormal phenomena may occur simultaneously due to a certain trouble .With this method ,you can reject some suspicious troubles and finally make a correct judgment .

7 Analysis of Troubles and Troubleshooting

A.Poor Refrigerating Effect

The so-called “poor refrigerating effect “ refers to the fact that the refrigerator can operate and refrigerator normally ,but the temperature in the refrigerator cannot drop to the prescribed value under the stipulated working conditions .In view of there are many causes for this phenomenon ,we are going to discuss and analyze it in the following 7 aspects :

1)Leakage of refrigerant Analysis of Trouble

The leakage of refrigerant in the system will result in an insufficient

refrigerating capacity ,the resulting phenomena are its lower gas suction pressure and exhaust pressure as well as higher exhaust gas temperature .The exhaust tube feels rather hot ,and a continuous gas flowing sound louder than usual can be heard at the outlet of the capillary ,and no frost or a smaller quantity of loose frost appears on the evaporator .After shut down ,the balance pressure in the system is usually lower than the saturation pressure corresponding to the same ambient temperature .

Remedy

In case there is leakage of refrigerant from the system ,do not hurry to recharge it with refrigerant ,manage to find out leak points immediately ,and make a note of from where it leaks ---welding points and parts .After having them repaired ,recharge refrigerant .
