Yes really. Each gram of water absorbs 600 cal during the phase change to vapor.

Sure. However doing so will also increase relative humidity. That's probably a non-issue at 40% but if it's already at 70% or higher, the effect of repeatedly vaporising water may actually worsen the situation in a closed room. Of course room size is another key factor.
