Students have asked these similar questions
Explain the principle of refrigeration system and its components
1. What other substance circulates in the
refrigeration system with the refrigerant?
2. What would happen if there were more refrigerant
in the system than the condenser and receiver
could hold?
It can be reasonably assumed that a refrigeration system has an adequate refrigerant charge when all the following criteria are met , except for
1. bubbles in the sight glass
2. no bubble in the sight glass
3. proper head pressure
4. proper suction pressure
