US Patent 10562407 Refrigerant shut off valve simplification

A vehicle system includes a refrigerant loop with a specific arrangement of valves and evaporators or heat exchangers to reduce the number of valves necessary. The vehicle system includes a refrigerant loop that includes a first thermal expansion valve downstream of a condenser and upstream of a first evaporator. A second thermal expansion valve is downstream of the condenser and upstream of a second evaporator. A third thermal expansion valve is upstream of a battery chiller. This arrangement allows for the valves to be simplified such that none of the thermal expansion valve include a binary shut-off valve. A multi-flow position valve may be positioned at a location that combines the outlet of the first and second evaporators.
