Abstract
A vehicle thermal system includes a thermal loop with a compressor, condenser, vapor injector, internal heat exchanger, chiller, and bypass valve, and a controller for operation during dehumidification. The controller opens an injector valve to inject vapor into the compressor and opens the bypass valve to reduce flow through the internal heat exchanger under a first condition.
Claims7
A vehicle thermal system comprising:
- a thermal loop including a compressor, condenser, vapor injector, internal heat exchanger, chiller, and bypass valve;
- and a controller programmed to, in response to a dehumidify request resulting in a dehumidification operation and in response to a first parameter value being less than a second parameter value, open an injector valve of the vapor injector such that the vapor injector injects vapor into the compressor, and open the bypass valve such that fluid-flow through the internal heat exchanger decreases.
