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.

A system including mode, engine, and battery modules, where the mode module determines whether to operate in an engine mode or a battery mode based on parameters. The engine module, while operating in the engine mode, runs a compressor at a first speed based on a temperature within a temperature controlled container of a vehicle and permits passage of refrigerant through eutectic plates independent of the temperature. A battery, while in the engine mode, is charged based on power received from an electrical source. The battery module, while operating in the battery mode and based on the temperature, runs the compressor at a second speed and prevents passage of the refrigerant through the eutectic plates. While in the battery mode, the battery is not being charged based on power from a shore power source and the electrical source from which power is received during the engine mode.

A parking cooler which is capable of battery powered operation during engine off operation. The parking cooler or air conditioning system may vary in cooling capacities to maximize cooling or maximize battery life. The parking cooler includes one or more condensers and a housing to accommodate such variation of cooling capacity.

There is disclosed a vehicular air-conditioning device of a so-called heat pump system which eliminates or decreases noise generated when an opening/closing valve opens at a changing time of an operation mode. The vehicular air-conditioning device executes a heating mode to let a refrigerant discharged from a compressor 2 radiate heat in a radiator 4, decompress the refrigerant by which heat has been radiated, and then let the refrigerant absorb heat in an outdoor heat exchanger 7, and a dehumidifying and heating mode to open a solenoid valve 22 in a state of the heating mode, decompress at least a part of the refrigerant flowing out from the radiator and then let the refrigerant absorb heat in a heat absorber 9. When the heating mode changes to the dehumidifying and heating mode, the controller decreases a radiator pressure or a pressure difference before and after the solenoid valve to a predetermined value or less, and then opens the solenoid valve 22.

Other embodiments are described and claimed.
