How will the difference in the readings of the thermometers of the psychrometer

How will the difference in the readings of the thermometers of the psychrometer, hanging in the room, change if water is poured on the floor?

The device psychrometric hygrometer is designed to measure the level of air humidity and its temperature. The simplest psychrometer consists of two glass thermometers, one dry, the other wet (wrapped in a damp cloth). When the water evaporates, the wet bulb is cooled. The lower the humidity in the environment, the faster the process of water evaporation in the psychrometer takes place. If you answer this question, then: the difference in thermometer readings will decrease.
