if the ambient air temperature is 85F (29C) and the relative humidity is 60%, than the dew point is temperature is 70F (21C).
Adjust the chiller`s temperature setpoint to 72F (22C) to prevent condensation

Taking 2 variables and getting a conclusion that supposedly fits all possibles doesn't work.

IF the relative humidity isn't 60% then the dew point changes.

IF the ambient air temperature isn't 29C then the dew point changes.

Stick to something you are good at, as Maths and Physics clearly aren't two of them.
