Claims23
A system for heating and cooling a vehicle, comprising:
- a heat pump comprising:
- a compressor configured in an engine compartment of the vehicle, and
- an evaporator configured in a sleeper or a cab of the vehicle;
- and
- a controller configured to select a cooling mode or a heating mode for the heat pump.
A method for heating and cooling a vehicle, comprising:
- sensing a temperature inside a sleeper of the vehicle;
- based on sensing the temperature, activating a compressor of a heat pump by a controller, wherein the compressor is configured in an engine compartment of the vehicle;
- setting a position of a reversing valve by the controller, wherein the position of the reversing valve sets the heat pump into one of a cooling mode and a heating mode;
- and
- flowing a refrigerant into an evaporator of the heat pump, wherein the evaporator is configured in the sleeper or a cab of the vehicle.
