Abstract: An air conditioning (A/C) system and method of controlling same is provided for a vehicle. The A/C system includes an evaporator, a desiccant dryer located downstream of the evaporator, and a compressor fluidly connected to the air evaporator. The A/C system also includes a plurality of sensors to provide inputs relating to temperature of the evaporator and relative humidity of an occupant compartment of the vehicle. The A/C system further includes an electronic control unit electrically connected to the sensors to receive the inputs therefrom and electrically connected to the desiccant dryer and the compressor to turn the desiccant dryer and the compressor On and Off to control the temperature and relative humidity of air to the occupant compartment.

Abstract: A climate control system for an electric vehicle includes a programmed microcomputer for controlling the pre-conditioning of the vehicle prior to usage as well as heating, ventilating and air conditioning of the vehicle under normal operating conditions. The microcomputer responds to a plurality of vehicle operator inputs and sensor inputs and provides outputs to control the speed of the compressor, condenser fan and blower fan, and the position of a temperature blend door and a Fresh Air/Recirculating Air door to optimize the use of electrical energy.
