Determine two-one illustrates just how much air has to be cooled prior to the distinction between the air temperature and dewpoint temperature equals zero and condensation takes place. Whatever the initial air temperature, once the relative humidity is rather superior only some degrees of cooling will result in condensation. As an example, if the bulk on the air in a very home has a RH of 80%, condensation will arise over a area which is only about 7oF (4oC) cooler than the majority place air temperature.
