摘要:
The invention relates to a controlled air-conditioning device for a vehicle comprising a compressor (2) which is driven by the vehicle engine (1) through a clutch unit (3), a condenser (7), at least one evaporator (8, 9) and a main circuit for coolant fluid flowing between the compressor (2), condenser (7) and the evaporator (8, 9). Said main circuit comprises a first line (30) for supplying fluid from the compressor (2) to the condenser (7), a second line (31) for supplying fluid from the condenser (7) to the evaporator (8, 9), a third line (32) which sucks fluid from the evaporator (8, 9) towards the compressor (2) and is provided with an additional circuit (33) disposed between the first line (30) and the third line (32) which returns gases exhausted by the compressor directly towards the suction thereof and comprises a controll device (5, 10) for switching on and off the additional circuit.

The atmosphere of a refrigeration space of a food transport vehicle is controlled by cooling the interior space of a preselected temperature by spraying liquid nitrogen within the space. After discontinuing the spraying, liquid nitrogen is conducted through a heat exchanger which extends across a portal communicating the space with ambient air. A ventilator (50) forces air through the portal (42) and the heat exchanger and into the space, whereby the ambient air is cooled and displaces gaseous nitrogen from the space. This creates a cold breathable atmosphere within the space to enable food to be loaded or unloaded. During the loading/unloading operation, liquid nitrogen can be conducted through an evaporator (40) disposed in the space to maintain the temperature in the space.

A heat radiating structure of an interior member is provided with a heat radiating portion (1) adapted to be applied to a vehicle and disposed on a rear surface of an interior member (6) whose surface is adapted to be applied with external energy, a heat receiving and radiating portion (2) connected to a vehicle body of the vehicle, and a reflecting member (3) allowing heat radiation, radiating from the heat radiating portion to an inside of the interior member, to be reflected and propagated to the heat receiving and radiating portion. The reflecting member cooperates with the heat radiating portion and the heat receiving and radiating portion to define a closed space.

摘要:
Zur Begrenzung der Temperatur des Fahrgastraumes sind erfindungsgemäß der Sonneneinstrahlung (26) ausgesetzte Teile des Fahrgastraumes jeweils mit einem Sonnenkollektor (10, 20) versehen, der einen Absorber (21) enthält, der zusammen mit einer transparenten Abdeckung (22) einen Strömungskanal (23) für die Fahrgastraumluft bildet. Die Aufheizung dieser Teile, insbesondere des Armaturenbretts (6) und der Hutablage (8), durch die Sonneneinstrahlung (26) wird somit entsprechend begrenzt.

摘要:
Passive radiative cooling structures and apparatus manufactured with such cooling structures conserve energy needs. A flexible film transparent to visible light incorporates particles at a volume percentage larger than 25% so as to absorb and emit infrared radiation at wavelengths where Earth's atmosphere is transparent. Another film transparent to visible light is thin and flexible and configured to absorb and emit infrared radiation at wavelengths where Earth's atmosphere is transparent, wherein etchings or depositions are present on one or both surfaces. A high efficiency cooling structure has an emissive layer sandwiched between a waveguide layer and a thermal conductive layer. A solar cell panel is covered by a transparent passive radiative cooling film. A container housing an active cooling unit incorporates passive radiative cooling structures on one or more exterior surfaces.
