How do you reduce the normal air temprature to 0 degree celcius ?

Question

In a given situation, if a small fan is blowing air in a container, what is the best way to cool air, to a point that, it becomes dew drops. What should be the best way to do that.

I had designed a container, with a fridge technology, using the same gas, as fridge uses, but still could not get it cold enough to make the air in dew drops. I want to ask, is this thing possible, and whaat would be the best design to make. I would welcome all kinds of ideas.

Answer 1

If you are using ambient air, you have to cool it to the dew point temperature to have the moisture to condense.

How much cooling is this?

Depends on the moisture content of the air. It may be very easy, if the air is humid, but you may need to cool a lot if it´s dry.

And it has nothinbg to do with the 0 C threshold. The dew point can be much higher or even below 0 C.

Answer 2

you can't unless you use ice or blow in the air

Answer 3

turn your AC to 32 fareinhiet or 0 celcius and get a humidafyer

Answer 4

moisture isn't just magically always abundantly in the air, sometimes its harder to get out of the air, you need a way of introducing moisture into the air, ie: a humidifier because your method is good but cant create moisture it has to be there already

Answer 5

you have to introduce the cold air to warm air to produce moisture.
