Opinion on mini pumps; and Maybe tune down dupe oxygen consumption a bit?

When talking about pumps for building a vacuum airlock inside two doors... did someone actually make the test between a small and big pump ? Energy consumption is low when these air lock are not passed through very often. But when there are more duplicants going through, the details start to matter. For instance, I used one of these airlock for my mushroom farm, to keep carbon dioxide in and oxygen out. But there are a lot of people working in this farm, so this might be inefficient.

In this specific case you don't really need a vacuum air lock since you don't temperature separation. A low pressure air lock would do the job just fine. It's basically the same as a vacuum airlock but instead of the pump needing to pump out increasingly smaller and smaller packets of air, it just stops at a pressure that is significantly lower than what would be acceptable outside the airlock on either side making sure that when opened, air always rushes in.

For the oxygen area you want it to be breathable so above 600g/tile should be absolute minimum. For the farm, the plant don't grow in less than 150g/tile so count on at least 300g/tile to keep a reasonable safety buffer. So if the air lock pressure is set shut off the pump at 100-200g/tile, no gas should escape to the wrong side.

EDIT: Basically the same as @BlueLance posted while typing this.

Ok, so let's consider sleet wheat farms or pincha peppernut farms, which are completely useless in the current state of the game, but whatever. Here a vacuum air lock can be used to separate the temperature between the farm and the rest of the colony.

There is no real way to stop the temperature needing to be adjusted if you ask me, Even if you created a vacuum once a dupe walks in you will have two gasses of different temperatures mixing and being sucked into a pipe and spat out at a different temperature. The good news is the amount of gas left in the chamber would be so small if you went for a low pressure one that the gasses wouldnt really change the temperature of your doors which are themselves the only other source of temperature change.

It just depends a lot on the pressure of the gasses though, High pressure will trigger faster gain/loss of temperature when in contact with doors and other gasses.

Only useless if you only plan on using mealwoods for your entire playtime  I wont lie, I abuse the heck out of mealwoods - but always eventually end up with all my farms set up and running, if only for completions sake..

The air sucked can be reconditioned. The important thing is that the farm temperature is stable.

If your using oxygen pump thingies that use water to make O2 and hydrogen. 

You can use 1 at the top to slowly pump hydrogen into the hydrogen generator. 

Using less power than the normal pump. It is a truly self powering system. 

Also it pumps at a slower rate allowing you to not worry about setting a pressure gauge exactly right. 

So the pump doesn't have to on and off all the time. 

 

Set 1 at bottom to pull co2 out of the base and over to some other area where you have that setup. 

 

Use 1 in a polluted o2 cooling area. 

Pumping a little bit of hydrogen through the polluted o2 cooling it down and not having to worry about a lot of the hydrogen heating up. 

Not talking about the pump you use to go to ac unit. 

This is seperate. 

 

Use it anywhere you want want small amounts of items moved. 

So you don't have to turn other pumps on and off. Saving you resources not only building the pumps but not as much need to worry about logistic switches in some places.
