System for heating and/or cooling an interior environment

A system comprises:

• a compressor system comprising,
• an electric motor;
• a compressor configured to be driven by the electric motor;
• a plurality of valves in fluid communication with an output of the compressor;
• a rotor disposed adjacent the valves and configured to spin as the valves control fluid movement toward the rotor;
• and
• a magnet coupled to the rotor and configured to spin within a stator, wherein the compressor causes fluid to move through the valves thereby causing the rotor to spin the magnet, which in turn generates an electrical current;
• an expansion valve in fluid communication with an evaporator;
• a receiver/dryer in fluid communication with the expansion valve;
• the compressor system in fluid communication with a low pressure side that is in fluid communication with the evaporator and a high pressure side in fluid communication with a condenser;
• and
• a fluid conduit coupled to a heater core and configured to receive a high pressure fluid via the high pressure side and further configured to direct the fluid to the compressor system, wherein the compressor system may be controlled to change a direction of flow of a coolant fluid to one or more of the evaporator and the heater core to provide selective heating or cooling.
