Refrigeration

In refrigeration systems pressures, temperatures and any system superheating or subcooling have to be checked for a system to function smoothly. Furthermore, the tightness of the system must be ensured and the source of any leaks must quickly be found if they occur. Thus a reliable statement about the safety and efficiency of the system based on these parameters can be stated.
