Psychrometric Processes Sensible Heating and Cooling A sensible process is one where the state of moist air is altered along a constant moisture content line t 1 1 w t 2 cooling heating t 2 Heating decrease in RH Cooling increase in RH Looking at the chart what happens to the relative humidity as you heat or cool sensibly? Note: Cannot cool sensibly below t DP why? Condensation removes water Sensible cooling and heating
