In figure A, there is no reheater, and the relative humidity is 61.3%.
In figure B, there is a reheater, and consequently a more powerful cooling coil. This cooling coil pulls the air down to a temperature lower than the cooling coil in figure A, causing more condensation.
After this, the heating coil raises the temperature of the air to the desired grill leaving temperature. The relative humidity achieved in the air conditioned space is 53.8%.
