In the case of over-cooling and shifting back to heating, the moistue will evaporate back into the space is 15 mins.
It is interesting to monitor. The cooling/heating cycle will repeat and a small amount of moistue will be removed at great cost.
Of course you know how a dehumidifier works. Moisture is removed and heat is returned to the space, which inturn lowers moisture and increases the temp which in turn reduces the amount of moisture that must be removed.
Some major a/c manufactures attempted several this concept years ago.
If you have this working some place, I would like to data log the processes. Cooling systems including dehumidifiers retain moisture on the cooling coil which will evaporate back into the space. The key is to remove enough moisture during the cycle to dramatically reduce the moisture in the air. Cooling/reheat cycle with over-cooling cycle is not long enough.
If you want further disscusion, please post the issues.
My main point was that giving advice about a concept that will not provide the intended effect should be avoided.
