A refrigeration cycle device includes: a compressor; a heat radiating unit that causes refrigerant to heat air supplied to a space inside a vehicle cabin; a decompression unit that decompresses the refrigerant; an outside air heat absorbing unit that causes the refrigerant to absorb heat from outside air; a waste heat absorbing unit that causes the refrigerant to absorb waste heat of a waste heat device; a shutter that opens and closes a passage for the outside air introduced into the outside air heat absorbing unit; and a control unit that closes the shutter when it is determined that an amount of waste heat of the waste heat device is larger than an amount of heat absorbed by the refrigerant in the outside air heat absorbing unit and the waste heat absorbing unit.

The objective of the present invention is to provide a compressor with which it is possible to simplify the manufacture of a soundproof cover. A compressor (1) is provided in an air conditioning device for an automobile. The compressor (1) is provided with: a main body portion which has a discharge port (12) and which compresses a refrigerant; and a soundproof cover (20) which includes a first cover (30) and a second cover (40), separate from the first cover (30), and inside which an internal space is formed, the main body portion being accommodated in the internal space. The soundproof cover (20) includes, in a part in which the first cover (30) and the second cover (40) face one another: a contacting portion (24) in which the first cover (30) and the second cover (40) are in contact with one another, thereby separating the internal space and an external space outside the soundproof cover (20); and a spaced-apart portion (25) in which the first cover (30) and the second cover (40) are separated from one another to form a first opening (26) connecting the internal space and the external space. The discharge port (12) is inserted through the first opening (26).

Features for a vapor compression system configured to cool and/or heat (i.e. thermally condition) two or more distinct climate controlled vehicle interior components via a common thermal bus are disclosed. Some embodiments employ a single compressor. Some embodiments employ multiple compressors and/or thermal buses, each servicing components located within respective interior thermal zones of a vehicle, for example a front row seat zone, second and/or third row seat zones, and/or an overhead zone and/or a trunk zone.

A thermal management system for a vehicle includes an ejector, which includes a main refrigerant line connected to allow a refrigerant to sequentially circulate through a compressor, a condenser and an evaporator, a first branch line which branches between the condenser and the evaporator of the main refrigerant line and which is connected to an inside of the nozzle of the ejector, a second branch line which branches between the evaporator and the compressor of the main refrigerant line and which is connected to an outside of the nozzle of the ejector, and a refrigerant increase line which is connected to an outlet of the ejector and which joins to the main refrigerant line through the compressor.

A thermal management system for a vehicle includes a plurality of fluid flow circuits including a heating ventilation and air conditioning (HVAC) circuit circulating a flow of refrigerant therethrough and including an evaporator, a chiller heat exchanger, a first expansion valve located upstream of the evaporator, a second expansion valve located upstream of the chiller heat exchanger, and a heat exchanger located fluidly upstream of the expansion valves. A propulsion cooling circuit circulates a flow of coolant therethrough which is utilized to condition one or more propulsion components of the vehicle. The flow of coolant is directed through the heat exchanger, thus subcooling the flow of refrigerant. A controller is operably connected to one or more control points of the thermal management system and is configured to adjust the one or more control points to achieve a target amount of subcooling of the flow of refrigerant at the heat exchanger.

There are provided a vehicle, a cooling apparatus, and a cooling method. The vehicle includes passenger space to accommodate a user gets, a tank to store the compressed air, and a control unit to release the compressed air stored in the tank into the passenger space. The passenger space is cooled by discharging the compressed air into the passenger space.

The present invention relates to compositions for use in refrigeration, air-conditioning, and heat pump systems wherein the composition comprises a fluoroolefin and at least one other component. The compositions of the present invention are useful in processes for producing cooling or heat, as heat transfer fluids, foam blowing agents, aerosol propellants, and fire suppression and fire extinguishing agents.

An air conditioning system for an electric transport vehicle supplied by an electrical supply network includes at least one actuator for the production of heat or cold, and a regulator configured in order to generate at least one operating command applied to the at least one actuator as a function of values for parameters representing the climatic conditions, the actuator delivering an average power over a predetermined time period. The regulator are configured in order to generate at least one operating command applied to at least one actuator as a function moreover of the value for a parameter relating to at least one electric transport vehicle supplied by the electrical supply network, the value for the parameter indicating that electrical energy is consumed by the at least one electric transport vehicle or that electrical energy is produced by the at least one electric vehicle.

A battery cooling system includes a cooling water circulation circuit for circulating cooling water for cooling the battery, a first heat exchanger for exchanging heat between air and cooling water, a second heat exchanger for exchanging heat between the low-pressure refrigerant of the refrigeration cycle circuit and cooling water, and an ion exchanger for removing impurity ions contained in the cooling water. The first heat exchanger and the second heat exchanger are arranged in series in the cooling water circulation circuit. The ion exchanger is disposed on the downstream side of the second heat exchanger in the cooling water circulation circuit.

A vehicle air conditioner is capable of selecting and changing an optimum operation mode so that a desirable air conditioning performance can be exerted on conditions such as an environment and a set temperature. A controller changes and executes at least one of a heating mode, a dehumidifying and heating mode, a dehumidifying and cooling mode, and a cooling mode. In the dehumidifying and heating mode, the controller shifts to the dehumidifying and cooling mode on the basis of a situation where heat absorption in a heat absorber (9) runs short or heat radiation in a radiator (4) becomes excessive, and also in this dehumidifying and cooling mode, the controller shifts to the dehumidifying and heating mode on the basis of a situation where the heat radiation in the radiator (4) runs short.
