Patent ID: 8051670

Claim:
A method of operating a vehicle including a prime mover operable in a first mode configured for driving the vehicle, and operable in a second mode configured for standby operation of the vehicle, the method comprising: providing a cabin including walls defining a space; insulating the cabin; providing a heating, ventilation, and air conditioning (“HVAC”) system in the vehicle, the HVAC system including a cooling system having an evaporator assembly, the evaporator assembly including a cooling coil, the HVAC system further including a heating system having a heating coil, and a sorption system having a desiccant; powering the HVAC system using a battery when the vehicle is in the first mode and when the vehicle is in the second mode; circulating a refrigerant through the evaporator assembly; circulating a coolant through the heating coil; selectively directing an airflow through one of the sorption system and a bypass, the sorption system adsorbing moisture from the airflow using the desiccant such that the airflow is substantially dehumidified by the sorption system, and the bypass directing the airflow around the sorption system without directing the airflow through the sorption system; directing the airflow from one of the sorption system and the bypass toward at least one of the evaporator assembly and the heater coil; conditioning the airflow via heat exchange relationship with one of the refrigerant flowing through the evaporator assembly and the coolant flowing through the heater coil; and conditioning the space using the conditioned airflow.
