Abstract
Presented is a vehicle thermal system. The vehicle thermal system comprises a thermal loop and a controller. The thermal loop includes a compressor, condenser, vapor injector, internal heat exchanger, chiller, and bypass valve. The controller, during a dehumidification operation, opens an injector valve of the vapor injector such that the vapor injector injects vapor into the compressor, and opens the bypass valve such that fluid flow through the internal heat exchanger decreases.
Claims12
A method comprising:
- responsive to occurrence of a first condition during a dehumidification operation of a thermal loop that includes a compressor, condenser, vapor injector, chiller, internal heat, exchanger, and bypass valve fluidly in parallel with the internal heat exchanger, closing the bypass valve such that fluid flow through the internal heat exchanger increases and an injector valve of the vapor injector remains closed.
A vehicle comprising:
- a cooling system including an injector valve configured to actuate between a first injector state permitting fluid flow through a vapor injector and a second injector state inhibiting fluid flow through the vapor injector, and a bypass valve configured to actuate between a first bypass state permitting fluid flow through an internal heat exchanger and a second bypass state inhibiting fluid flow through the internal heat exchanger;
- and
- a controller programmed to, responsive to occurrence of a first condition during a dehumidification operation, actuate the bypass valve from the second bypass state to the first bypass state while the injector valve remains in the second injector state.
