HVAC&R HUMIDITY CONTROL SYSTEM AND METHOD.

摘要

A controller controls operation of a HVAC&R device to reduce an int erior humidity level for a structure to provide comfort for occupants of the structure. The controller includes a first sensor for sensing a temperature inside a structure and a second sensor for sensing a humidity level inside the structure. A controlle r is responsive to the first and second sensors for the HVAC&R device operati ng in a cooling mode to reduce the humidity level inside the structure. The controll er calculates a temperature correction to a predetermined temperature setting f or the HVAC&R device, the temperature correction calculation being obtained by subtracting the sensed humidity level from a predetermined humidity level an d dividing the result by a predetermined factor. The controller initiates operation of the HVAC&R device when the sum of the sensed temperature and the tempera ture correction is greater than the predetermined temperature.
