DBT increases in sensible heating while DBT temp increases WBT increases.

On Psychometric chart Dry Bulb temp. Increases from left to right. During sensible heating process specific humidity remains constant (i.e. process is showed by horizontal line). So as we move from left to right WBT lines (inclined lines) increases from Bottom left corner to upper right corner. So we can clearly say that WBT increases. Description can easily understood by Psychometric chart.

If you observe your psychrometric chart, you will observe that the enthalpy and WBT line travel proportionally. In sensible heating the path of process is along the +ve y-axis. Thus you will observe that the three lines of enthalpy, heating and WBT are proportional to each other. Hence.

It states that specific humidity constant and there was a change (increase & decrease) in wet bulb temperature in sensible process. (heating & cooling).

DBT increase then WBT also increase humidity remains constant.

In latent heating the temperatures remains constant the phases will be changed. But sensible heating the temperature will increased further. So that the wet bulb temperature is increased.

Wet bulb temperature means environmental temperature when the increasing of air temperature then automatically the wet bulb temperature also increased.

When the sensible of heat of the air increases, the wet bulb temperature decrease down. Because, the moisture in the air expands.

As we know heat flow from higher temperature. To lower temperature so wet bulb will dry means the temperature of wet bulb will increase due to the temperature of air.

As sensible heating is done of air the temp. Will increase & thus the temp. Of wet bulb is also increased.
