Abstract
Methods and systems for providing controlling environmental conditions in a passenger compartment of a vehicle are presented. In one example, various low cost expansion valves are included in a system that has a receiver positioned downstream of an exterior heat exchanger to provide a climate control system with heating, cooling, dehumidification, and de-icing modes.
Claims20
A vehicle system, comprising:
- a coolant loop including a heater core in a passenger compartment;
- and
- a refrigerant loop including a first thermal expansion valve that does not include an electrically variable orifice positioned directly upstream of a heat exchanger in the passenger compartment, the refrigerant loop fluidically isolated from the coolant loop, the refrigerant loop in thermal communication with the coolant loop via an intermediate heat exchanger.
A vehicle system, comprising:
- a coolant loop including a heater core in a passenger compartment;
- and
- a refrigerant loop including a first thermal expansion valve that does not include an electrically variable orifice positioned upstream of a heat exchanger in the passenger compartment, the refrigerant loop including a receiver directly coupled to an exterior heat exchanger, the refrigerant loop in thermal communication with the coolant loop via a heat exchanger.
A vehicle climate control method, comprising:
- receiving refrigerant to a receiver positioned downstream of an exterior heat exchanger in a climate control system that includes an exterior heat exchanger, an interior heat exchanger, an internal heat exchanger, the refrigerant received in a cooling mode, a heating mode, a de-icing mode, and a dehumidification mode.
