Abstract
A vehicle includes an engine cooling system. The engine cooling system includes an engine. A radiator is fluidly coupled to the engine. A sensor is configured to provide a temperature reading of a coolant at the engine. The vehicle further includes a heat pump system. The heat pump system includes a condenser disposed proximate the radiator and fluidly coupled to the compressor. An evaporator is fluidly coupled to the condenser. A climate fan is fluidly coupled to an exterior surface of the evaporator. A climate control module is configured to control a speed of the climate fan. The climate control module establishes a maximum speed of the climate fan in response to a temperature reading from the sensor.
