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.
Air to air exchanger vs dehumidifier.
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.
Like an erv a ventilating dehumidifier introduces fresh air from outside your home filters it and removes indoor air for consistent circulation.
The heat exchanger is not 100 effective so there is some sensible cooling from the sd 12 in addition to the dehumidification.
Having your ac on for 24 7 will definitely leady to a higher power bill.
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.
They are really a quite simple machine.
I would recommend not.
They work by sucking in air which is then rapidly cooled down.
Cooling dehumidifier heat exchanger main features finned tube heat exchanger type for dehumidification of air by means of condensation by using ice water or other cooling media flowing through the heat exchanger tubes followed by a demister and re heater steam or hot water to heat up the air above the dew point.
