Is it necessary to install a manual valve on the exhaust pipe of the non-condensable gas outlet of the heat exchanger? Is it better to leave it open?
Since there is non-condensable gas, then it’s necessary
It then depends on whether you have confidence in your own design
Is that the hand valve that is turned on and off frequently? When should the valve be opened and closed?
Since there is non-condensable gas emission, it is necessary; how can it be left uncovered? Are non-condensable gases also released together? It should be released regularly when needed.
Can automatic control be achieved? How to control it?
It’s hard to say; it depends on your medium and operating conditions to determine.
Generally, exhaust ventilation is turned on at the beginning of use; once there is no more gas, it is turned off. Subsequently, the heat exchange performance is monitored, and if it is poor, an inspection is carried out. A timed exhaust function can also be set up, and for chemical media, ease of recovery must be taken into consideration.
