Dehumidifiers

I realize dehumidifers are rated by how many pints of moisture they remove/hr, but how is that determine ? Is it determined by the number of fin's on the condenser or the size of the compressor or something else....

They are rated based on energy used vs. water removed = Pints/kWh. The link is a listing of Energy Star rated units. Check out how much more Teddy Bear's Therma-stor units extract.

I understand that but it still doesn't answer my question as to how they come up with how much the dehunidifer will remove. Is it the size of the comressor or the condenser that makes one remove more water then the other ??? How do they get one to remove 30 pints and another to remove 50 pints is what I want to know.

4. The size of the compressor is the primary driver. However, there also has to be enough 'fins' to match the compressor size. So, the size of everything goes up to increase capacity.

It takes X amount of energy to condense X amount of water at a specific temperature and humidity in the space the dehumidifier is located in.
The energy/capacity is going to be directly tied to the capacity of the compressor to convert electrical energy into the required temperature on the condensing/evap coil so it's surface will maintain a temperature below dew point.
So yes, it's dependant on both.

6. Its by how cold their coil gets, at what the air flow over the evap coil is, at x &#176; room air temp.
