mmonia and air pass through the heat exchanger. While the ammonia is entering as a superheated vapor at 16 bar pressure and 60C temperature it is leaving as a saturated liquid at the same pressure but unknown temperature. The ammonia mass flow rate is 400 kg/hour. Air is flowing backward and is heated from 17C to 42C at the constant pressure of 2 bars.

Heat Exchangers

Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.

Heat Exchanger

The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
