Normal operation of a condenser should include an outlet gas maximum temperature set point and a fixed inlet and outlet coolant/refrigerant temperature. The outlet gas temperature is a critical indicator of the efficiency of a condenser.
Concepts in Condenser System (Vacuum Equipment)This type of condenser has high pressure water jet nozzles fitted in the lower section of the condenser, directed straight at the outlet or barometric leg. The vapor inlet to the condenser is from the top of the condenser much above the level of the jet. The nozzles are called as jet nozzles and they create vacuum in the system.
