Abstract

An automobile which includes a radiator fan control for heat pump HVAC which can selectively reverse fan direction based on ambient temperature and moisture to reduce ice buildup on a liquid-gas converter. The automobile may include a liquid-gas converter located within an engine bay, a radiator located adjacent the liquid-gas converter, a first fan located adjacent the radiator, a fuel cell and motor with the inverter located adjacent the first fan, the fuel cell supplying electricity to the motor with the inverter to drive the vehicle. The automobile can also include a temperature sensor located on an exterior surface of the automobile to sense an ambient temperature, a heater core connected to the liquid-gas converter and located between the engine bay and the passenger area, and a control unit connected to the first fan, the temperature sensor, and the heater core.
