Abstract
Methods and apparatus for controlling the cooling set point value of a climate control system are provided. In one illustrative embodiment, a humidity error is determined as a function of the actual humidity in the inside space and a humidity set point value. The cooling set point value is then adjusted by a cooling offset that is a function of the humidity error. Under humid conditions, and when insufficient dehumidification occurs during a normal cooling cycle, lowering the cooling set point may provide further dehumidification, which may improve comfort in the inside space. Under less humid conditions, and when the humidity level in the inside space is already below the humidity set point value, increasing the cooling set point value may lower the energy usage of the climate control system while still providing comfort.
