The heat exchanger is not 100 effective so there is some sensible cooling from the sd 12 in addition to the dehumidification.
Air to air exchanger vs dehumidifier.
They work by sucking in air which is then rapidly cooled down.
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.
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.
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.
In energy use dehumidifier vs air conditioner the debate is not so all encompassing because there are many types of air conditioners and dehumidifiers.
Dehumidifier vs air conditioner energy use.
Like an erv a ventilating dehumidifier introduces fresh air from outside your home filters it and removes indoor air for consistent circulation.
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.
They are really a quite simple machine.
