Abstract
An apparatus is disclosed for an improved air conditioning system for admitting air from an exterior space, adjusting the temperature and humidity of the exterior air and delivering the adjusted air to an interior space of a structure. To compare the energy levels of these two air streams an improved device brings both air streams to the same temperature, so just the relative humidity has to be measured to know which of these two air streams has the higher or the lower energy level. Using the device in a control system for a desiccant wheel, at least two temperature sensors are eliminateable.
