Abstract
In an air conditioning system for selectably heating and cooling an enclosed space under control of a room thermostat, dew point temperature of ambient air in the space is maintained below a preselected maximum value by modified use of the heating and cooling apparatus without separate humidity control. For this purpose the cooling apparatus is controlled by a sensor responsive to absolute moisture content in parallel with the normal thermostat control. Energy is further conserved by night set-back of the thermostat with cooling apparatus normally disabled in night set-back.
