The present invention relates to an air conditioner for a vehicle, which includes an air-conditioning case (200), and at least one door (100) mounted to be opened and closed at a predetermined position, wherein the door (100) is formed integrally with an arm pivot (140), and the arm pivot (140) includes a pin part, and ribs formed integrally with both sides of the pin part to reinforce rigidity of the pin part and offset noise. The air conditioner further includes distortion preventing parts formed on a rotary shaft to be dented and to be crossed to each other, thereby reducing a transformation rate of the door and securing accuracy of the pin part.

A vehicle air-conditioning controller includes a battery temperature sensor configured to detect a battery temperature of a battery, a cooling-air temperature sensor configured to detect a temperature of cooling air that has passed an evaporator, and an air-conditioning ECU configured to determine a target ejection temperature of air to be ejected into a vehicle interior from an air conditioner. The air-conditioning ECU is configured to control a cooling device to cool the battery, during air conditioning of the vehicle interior through remote operation external of the vehicle, when the battery temperature is at a predetermined temperature or higher and a state wherein the difference between the target ejection temperature and the cooling-air temperature has been at or below a predetermined value for a predetermined time period.

1. Method, device and system for operating internal combustion engines with a considerably increased pressure ratio and vehicle with this system.

2.1 Internal combustion engines have a technically restricted pressure ratio, which limits the thermal efficiency. Gas turbines have so far had a maximum pressure ratio of 33:1, diesel engines have compression ratios of up to 23:1.

2.2 The oxidizer is fed into the combustion chamber in (cold) liquefied condition under very high pressure (1-2). The fuel is ideally also supplied in liquid form under high pressure. The pressure ratio of the oxidizer pump is 200, better 500 or more. In the combustion chamber, the oxidizer and fuel react with each other (2-3) and expand to far more than a thousand times the liquid volume. Depending on the fuel used, an expansion machine with a pressure ratio of around π=500 or more or an equivalent expansion ratio of ε=85 or more can be implemented (3-4).

2.3 The method enables the development of compact, cost-effective internal combustion engines with significantly increased efficiency, which are particularly suitable as vehicle propulsion systems.

A cooling system includes a coolant transmitter that transmits coolant at a pressure greater than atmospheric pressure. The cooling system also includes an evaporation vessel at atmospheric pressure. The evaporation vessel can contain an amount of coolant at the boiling point of the coolant. The cooling system also includes a pressure reducer fluidically coupled to the coolant transmitter and the evaporation vessel. The pressure reducer can include an orifice. The cooling system is configured such that heat is transferred from the coolant in the coolant transmitter to the coolant contained in the evaporation vessel. An exit stream conduit can fluidically couple the coolant transmitter and the pressure reducer, with the exit stream conduit diverting a portion of the coolant from the coolant transmitter to the evaporation vessel.

A cooling system using carbon dioxide as a coolant comprises a cooling chamber for storing products to be cooled during transport and a cooling unit for cooling the atmosphere in the cooling chamber. The cooling chamber and the cooling unit are mounted on or integrated in a cooling vehicle like a truck, a railway wagon or a ship. The cooling unit comprises a carbon dioxide storage compartment and at least one cooling channel through which air is led from and to the cooling chamber. The carbon dioxide storage compartment and the cooling channel are separated from each other by a thermal well-conducting but gas-tight plate serving as a heat exchanger between the carbon dioxide in the carbon dioxide storage compartment and the air in the cooling channel.

Systems and methods for cooling a datacenter are disclosed. In at least one embodiment, an absorption chiller includes a generator vessel to enable removal of heat from fluid returned from at least one computing component of the datacenter.

Disclosed is a system for managing power in a transport refrigeration unit (TRU) installed on a trailer, having: a TRU controller configured to execute a range extender mode of operation to manage operations of the TRU and TRU components, wherein the TRU controller: selects a power management strategy from a plurality of demand-side power management strategies; determines, from the selected power management strategy, operational parameters for a TRU; and executes the generated operational parameters.

A fuel storage and delivery system for a refrigerated cargo vehicle. The system includes a first fuel tank for storing natural gas and a second fuel tank for storing natural gas, at least the first fuel tank is for storing the natural gas as liquefied natural gas (LNG); a vehicle fuel supply line fluidly connected to the first fuel tank for supplying fuel from the first fuel tank to a vehicle engine; and a refrigeration unit fuel supply line fluidly connected to the second fuel tank for supplying fuel from the second fuel tank to a transport refrigeration unit engine.

The system further comprises a water pump and one or more air blowers coupled to the water pump. The system further comprises a battery configured to supply power to the water pump and the one or more air blowers. The method comprises storing water in a water tank the water tank positioned within a housing on the vehicle. The method further comprises powering a water pump, via a battery, and pumping water from the water pump out of one or misting tips. The method further comprises providing one or more air blowers that distributes cold air and water coming out the misting tips.

A first header tank and a second header tank of a cold-storage heat exchanger are located away from each other. Refrigerant tubes include refrigerant passages through which the first header tank and the second header tank communicate with each other. The refrigerant tubes are spaced away from each other. Cold energy containers storing cold energy storage members are provided to close air passage portions defined between the refrigerant pipes. A region including the air passage portions are separated into a first region including a center part of the region and a second region that is remaining part of the region. A proportion of the cold energy containers in the second region is larger than that in the first region.
