TROUBLE SHOOTING OF A SIMPLE VAPOUR COMPRESSION REFRIGERATION S YSTEM.

WHAT IS A VAPOUR COMPRESSION REFRIGERATION SYSTEM?
A vapour compression refrigerating system is an improved type of air refrigeration system in which a suitable working substance termed refrigerant is used.It condenses and evaporates at temperatures and pressures close to the atmospheric conditions.The refrigerants usually used for this purposes are ammonia,Carbon dioxide and sulphur dioxide.The refrigerant used does not leave the system but is circulated throughout the system.
TROUBLESHOOTING TECHNIQUES.
The first thing to check for is refrigerant leakages
Secondly check if the compressors,condensers and evaporators are working.
