Dehumidifier vs air conditioner energy use.
Air to air exchanger vs dehumidifier.
In our climate zone the best equipment for ventilating your home and dehumidifying indoor air is a whole house dehumidifier with positive pressure from fresh outdoor air.
Having your ac on for 24 7 will definitely leady to a higher power bill.
You will want to run a dehumidifier in the summer because if you bring air in from outside it will contain humidity possibly more than what is already in the basement.
I would recommend not.
A dehumidifier is a machine that is used to suck that moisture out of the air with the main goal of drying the air in your home.
They are really a quite simple machine.
The heat exchanger is not 100 effective so there is some sensible cooling from the sd 12 in addition to the dehumidification.
They work by sucking in air which is then rapidly cooled down.
The supply air temperature from the sd 12 is significantly closer to the return air temperature than a typical ac system but it is still a lower temperature than the return air temperature.
