Question about relative humidity

[A.Mortezania]

Hi friends,

Sorry if my question is very simple.

In an empty cold room, By decreasing temperature (via evaporator) relative humidity of cold room will change ? Or relative humidity has not any relation with temperature of room ?

Thanks.

When temperature rises, relative humidity decreases and vice versa.

Have a look at a physcometric chart to see what happens when conditions change.
