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 transport refrigeration system (TRS) includes a first heat transfer circuit including a first compressor, a condenser, a first expansion device, and a cascade heat exchanger. The first compressor, the condenser, the first expansion device, and the cascade heat exchanger are in fluid communication such that a first heat transfer fluid can flow therethrough. The TRS includes a second heat transfer circuit including a second compressor, the cascade heat exchanger, a second expansion device, and an evaporator. The second compressor, the cascade heat exchanger, the second expansion device, and the evaporator are in fluid communication such that a second heat transfer fluid can flow therethrough. The first heat transfer circuit and the second heat transfer circuit are arranged in thermal communication at the cascade heat exchanger such that the first heat transfer fluid and the second heat transfer fluid are in a heat exchange relationship at the cascade heat exchanger.

An air conditioning system for motor vehicles includes a compressor, a condenser, a plurality of air conditioning units connected in parallel with each other with respect to the compressor and the condenser, and a flow rate control unit configured to, when a specific one of the air conditioning units is additionally turned on or is turned off, prevent occurrence of a sudden change in refrigerant amount in the remaining air conditioning units.

A refrigerant that has flowed out of a liquid ejector radiates heat in a radiator, and a liquid-phase refrigerant that has radiated heat in the radiator flows into an ejection refrigerant passage of the liquid ejector. A discharged refrigerant of a compressor that suctions the refrigerant that has flowed out of a low-pressure evaporator flows into an inflow refrigerant passage of the liquid ejector. An ejector adopted as the liquid ejector is one in which an ejection refrigerant is ejected from the ejection refrigerant passage to a gas-liquid mixing portion, and the ejection refrigerant is ejected on an outer circumferential side of the inflow refrigerant flowing from the inflow refrigerant passage into the gas-liquid mixing portion.

An integrated heat exchanger assembly comprises a first header tank, a second header tank, a first heat exchanger core extending between the first header tank and the second header tank, a second heat exchanger core extending between the first header tank and the second header tank, and a third heat exchanger core extending between the first header tank and the second header tank. The first heat exchanger core is in fluid communication with a liquid coolant and a refrigerant, the second heat exchanger core in fluid communication with a first portion of a flow of air and the refrigerant, and the third heat exchanger core in fluid communication with a second portion of the flow of the air and the liquid coolant.

A 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 a second heat exchanger and a first control valve that is movable between a first position allowing fluid flow through the second heat exchanger and a second position restricting fluid flow through the second heat exchanger. The second working fluid flow path may receive working fluid from the first heat exchanger and may include a third heat exchanger and a second control valve that is movable between a first position allowing fluid flow through the third heat exchanger and a second position restricting fluid flow through the third heat exchanger.

A technique for providing cooling in a firefighting vehicle leverages the availability of firefighting fluid for cooling the vehicle's components. By tapping into a conduit or manifold that receives firefighting fluid to be sprayed toward a fire, an amount of cooling fluid is drawn and directed through one or more liquid-to-liquid heat exchangers, for providing cooling of the vehicle's components.

A method for controlling coolant flow and cooling of a heater core to be used as a cold storage device or heater core cold storage (HCCS) cooling of a vehicle to extend an engine auto-stop period includes determining if at least one predetermined condition is met for HCCS cooling, and charging a heater core for a predetermined charge period in preparation for HCCS cooling when the at least one predetermined condition is met. The charge is held in the heater core until a trigger event occurs and HCCS cooling is initiated. HCCS cooling is then performed until a predetermined use period expires.
