METHOD AND SYSTEM FOR HEATING A VEHICLE

摘要

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.

主权项

1. 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.
