Why Relief v/v is
provided in condenser of refeer system.
Ans- If ur condenser
not cooling properly there will be chances of developing excess pressure because
of this pressure your hp will activated if hp will not work at that time this
relief vlv comes in action and remove excess pressure so it prevent us from
serious damage as a secondary arrangement after hp trip.
Condenser tubes
gets excess pressure when there is air in system or the compresser has to do
more work when sea water temp is high in certain areas which leads to increase
in pressure thus for ensuring safety since HP trip failure chances are very
common onboard.
