Abstract
Disclosed are climate systems for vehicles and methods for controlling the climate systems. In some implementations, a climate system includes: (1) a temperature sensor configured to measure a temperature within the compartment of the vehicle; (2) a user interface configured to receive a desired temperature from a user; (3) a first compressor powered by an engine of the vehicle to compress a refrigerant; (4) a second compressor driven by an electric motor to compress the refrigerant; and (5) a controller electrically coupled to the first compressor and the second compressor. The controller configured to: (1) calculate a thermal load of the compartment based on a difference between a desired temperature and a measured temperature; and, (2) based on the calculated load, selectively activate: (i) the engine, (ii) the first compressor, and/or (iii) the second compressor.
