Abstract
Systems and methods for heating and cooling a vehicle using a heat pump are disclosed herein. In one embodiment, a system for heating and cooling the vehicle includes a heat pump having: a compressor located in an engine compartment of the vehicle, and an evaporator located in a sleeper or a cab of the vehicle. The system also includes a controller for selecting a cooling mode or a heating mode for the heat pump.
Claims20
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;
- a controller configured to select a cooling mode or a heating mode for the heat pump;
- and
- a heater of an engine of the vehicle, wherein the heater is fluidly connected to the evaporator;
- wherein the controller comprises:
- a processor;
- and
- a memory, operatively connected to the processor, storing instructions that, when executed, cause the system to:
- sense a temperature inside the sleeper of the vehicle;
- based on sensing the temperature, activate the compressor;
- flow a refrigerant into the evaporator;
- before the engine is started, operate the compressor from a battery;
- before the engine is started, transfer heat from the evaporator to the heater by flowing the refrigerant from the evaporator to the heater of the engine;
- after the engine is started, terminate operating the compressor from the battery and initiate charging the battery.

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;
- flowing a refrigerant into an evaporator of the heat pump, wherein the evaporator is configured in the sleeper or a cab of the vehicle;
- before the engine is started, operating the compressor from a battery;
- before the engine is started, transferring heat from the evaporator to the heater by flowing the refrigerant from the evaporator to the heater of the engine;
- after the engine is started, terminating operating the compressor from the battery and initiate charging the battery.

- and
- a heater of an engine of the vehicle, wherein the heater is fluidly connected to the evaporator;
- wherein the controller comprises:
- a processor;
- and
- a memory, operatively connected to the processor, storing instructions that, when executed, cause the system to:
- sense a temperature inside the sleeper of the vehicle;
- based on sensing the temperature, activate the compressor;
- flow a refrigerant into the evaporator;
- before the engine is started, operate the compressor from a battery;
- before the engine is started, transfer heat from the evaporator to the heater by flowing the refrigerant from the evaporator to the heater of the engine;
- after the engine is started, terminate operating the compressor from the battery and initiate charging the battery.
