A system is provided that includes mode, engine, and battery modules. The mode module is configured to determine 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 refrigeration system may include a compressor, a first heat exchanger, a first working fluid flow path, and a second working fluid flow path. The first heat exchanger receives working fluid discharged from the compressor. The first working fluid flow path may receive working fluid from the first heat exchanger and may include an evaporator and an evaporator control valve that is movable between a first position allowing fluid flow through the evaporator and a second position restricting fluid flow through the evaporator. The second working fluid flow path may receive working fluid from the first heat exchanger and may include a eutectic plate and a plate control valve that is movable between a first position allowing fluid flow through the eutectic plate and a second position restricting fluid flow through the eutectic plate.

A system is provided that includes mode, shore power, engine, and battery modules. The mode module determines whether to operate in a shore power, engine, or battery mode based on parameters. The shore power module, while in the shore power mode, runs a compressor at a speed based on a temperature within a container of a vehicle and limits the speed to a first speed. A battery is charged based on utility power while in the shore power mode. The engine module, while in the engine mode, limits the compressor speed to a second speed. The battery, while in the engine mode, is charged based on power received from an alternator/generator. The battery module, while in the battery mode, limits the compressor speed to a third speed. While in the battery mode, the battery is not being charged based on power from a shore power source and the alternator/generator.

The first bypass passage branches at a point of a coolant passage from a cooling portion of a heating component the vehicle to the second water-refrigerant heat exchanger, and the first bypass passage is capable of being communicated with the coolant passage at an upstream side of the first water-refrigerant heat exchanger. The second bypass passage bran at a point of the coolant passage from a heater core to the first water-refrigerant heat exchanger, and the second bypass passage is capable of being communicated with the coolant passage at a downstream side of the first water-refrigerant heat exchanger. A part of the first bypass passage which includes a downstream end and a part of the second bypass passage which includes an upstream end are shared.

A rankine cycle system (1), a rankine-refrigeration cycle system (2) and a refrigerated vehicle are disclosed. The rankine cycle system (1) comprises a first evaporator (11), an expander (12), a condenser (13) and a refrigerant pump (14) connected in sequence to form a cycle, wherein the rankine cycle system (1) further comprises an electric heating device (15) connected between the refrigerant pump (14) and the expander (12) for heating the refrigerant. When the rankine cycle system (1) has no waste heat source, the present application can continue to provide energy to the rankine cycle through the electric heating device (15), thereby enabling the expander (12) to continuously and effectively output mechanical work. Even without a waste heat source, the rankine cycle can still operate normally, thus adapting to more operating conditions.

A refrigeration system comprises a compressor, a condenser, a reservoir, a throttling device, an evaporator, and a cooling device for cooling high-temperature components connected in sequence through pipes. The cooling device has a heat exchange container and a flow pipe, where the heat exchange container maintains fluid communication with the reservoir through the flow pipe, and the heat exchange container is used to absorb heat of the high-temperature components. The heat exchange container receives liquid refrigerant from the reservoir through the flow pipe, the liquid refrigerant in the heat exchange container generates vapor after heat exchange with heat absorbed from the high-temperature components, and the vapor enters the reservoir through the flow pipe, thus forming a circulation loop. Also described is a refrigerator van configured with a refrigeration system.

A road vehicle has a support frame; a passenger compartment; an outer body; and a pneumatic duct, which opens outwards through the outer body, and houses, on the inside, a cooling unit provided with at least two radiators movable relative to one another between a first operating position, in which the radiators substantially overlap one another and the cooling unit has a minimum exchange surface, and a second operating position, in which the radiators are substantially offset relative to one another and the cooling unit has a maximum exchange surface.

A vehicle thermal management system includes a first coolant loop that passes through a battery and a first valve. A second coolant loop passes through a heater, a cabin, and a second valve. A first connecting path connects the first valve and a second point of the second coolant loop. A second connecting path connects the second valve and a first point of the first coolant loop. The first valve selectively allows coolant to circulate through the first coolant loop or flow to the second point 280 through the first connecting path. The second valve selectively allows coolant to circulate through the second coolant loop or flow to the first point 180 through the second connecting path. A second cooling unit cools the cabin. The first coolant loop additionally passes through a first cooling unit.
