How Do Vacuum Pumps Work?
Engineers in the fields of air conditioning and refrigeration frequently employ vacuum pumps to remove air or non-condensables like water from the system. These must be eliminated from the system since they reduce the refrigeration system’s efficiency and have the potential to corrode internal components.
Before a new system is charged or after certain repairs have been made to an existing system where the refrigerant has already been recovered, this procedure is carried out. In either scenario, the system may have been contaminated by air and moisture.
