Dehumidifier vs air conditioner energy use.
Air to air exchanger vs dehumidifier.
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.
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.
Having your ac on for 24 7 will definitely leady to a higher power bill.
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.
They are really a quite simple machine.
In energy use dehumidifier vs air conditioner the debate is not so all encompassing because there are many types of air conditioners and dehumidifiers.
They work by sucking in air which is then rapidly cooled down.
The heat exchanger is not 100 effective so there is some sensible cooling from the sd 12 in addition to the dehumidification.
