Air Exchanger Or Dehumidifier
Since it is a basement the dehumidifier is not a bad thing.
Air exchanger or dehumidifier. Dehumidifier air conditioning uses what is called spot cooling to control the humidity in a room. As the other poster said the fresh air ventilation has nothing to do with dehumidification. 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. 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.
Tjernlund makes a good one. In a ventilation dehumidifier equipped with a heat pump the heat pump functions both as a dehumidifier and a dedicated heat pump. 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. Air conditioner dehumidifier can be one and the same because the same component found in a dehumidifier is also found in an ac.
Ac dehumidifier also has a condenser evaporator and metering device to gauge the air in the room. Like an erv a ventilating dehumidifier introduces fresh air from outside your home filters it and removes indoor air for consistent circulation. The energy from the warm humid air in the swimming pool room is recovered in the heat recovery section normally in a plate heat exchanger. Call your contractor and have him check it out.
Try the air exchanger. Indoor air contamination continues to rise with time and oxygen levels continue to fall a fresh air exchange is crucial to good long term health. Dehumidification should be done by a dehumidifier and fresh air exchange should be done by an air to air exchanger hrv erv etc. The heat exchanger is not 100 effective so there is some sensible cooling from the sd 12 in addition to the dehumidification.
