Abstract:
The present invention relates to an air conditioning system (10) for an aircraft cabin (12) with at least one air inlet (14) for supplying air to the cabin (12), at least one air outlet (16) for discharging air from the cabin (12) and at least one compressed-air source (52, 54, 56), which is adapted to provide pressurised fresh air for supplying to the cabin (12) via the at least one air inlet (14). The air conditioning system (10) further comprises a heat exchanger (42) supplied with ram air from a ram air inlet (92) for cooling air from the compressed-air source (52, 54, 56), wherein the heat exchanger (42) is disposed upstream of the air inlet (14) of the cabin (12). It is intended that the air conditioning system (10) comprises a cabin air heat exchanger (100) which is designed to be supplied with air discharged from the cabin (12), wherein the cabin air heat exchanger (100) is disposed downstream of the at least one air outlet (16) and upstream of a point (N) at which fresh air is mixed with air from the cabin (12).
Abstract:
The invention relates to a system for air conditioning at least one partial region of an airplane, comprising an air supply device (18) for providing a region of the airplane that is to be ventilated with a desired temperature and with a desired pressure of the air to be fed. An air supply duct (20) is connected to the air supply device at a first end. A second end of the air supply duct (20) is connected to an air inlet (24) ending in the region of the airplane to be ventilated, located close to the floor. A control device (26) is provided in order to ensure that the air provided by the air supply device enters the region of the airplane to be ventilated via the air inlet with such a speed that the air is distributed close to the floor in the region of the airplane to be ventilated and rises at heat sources present in the region of the airplane to be ventilated. The air provided from the air supply system enters the region of the airplane to be ventilated with such a temperature via the air inlet that the desired room temperature is achieved in the region of the airplane to be ventilated.
Abstract:
A primary system (20), comprising a compressor (21), a vapor separator (55), a heat exchanger (30), and an expansion device (22) connected in order to each other, wherein inside air is taken in as a primary air and exhausted to the outdoor; a secondary system (40), comprising a secondary inlet duct (43) and a secondary outlet duct (44) connected to the heat exchanger (30), wherein outside air is taken in as a secondary air and supplied to the indoor; a vacuum pump (36) is connected to the steam separator (55) which separates vapor from the compressed primary air and dehumidifies the primary air to below the absolute humidity of the outside air, the vapor from the steam separator (55) is supplied partly to the secondary air inside the secondary outlet duct (44), and the humidified secondary air is supplied to the indoor.
Abstract:
Ce dispositif comporte un corps creux délimitant une enceinte de génération, des moyens de génération de gouttelettes à partir d'un jet de liquide (J) s'écoulant à l'intérieur de ladite enceinte, des moyens d'évacuation d'une majeure partie du jet de liquide, ainsi que des moyens de diffusion de gouttelettes d'un brouillard, formé à partir dudit jet. Selon l'invention, l'enceinte de génération comprend une chambre amont (5) dite chambre commune, destinée à l'écoulement à la fois du liquide et des gouttelettes de brouillard, cette chambre s'étendant axialement en référence à l'enceinte,les moyens de diffusion comprennent au moins une branche de diffusion (6, 7) s'étendant de manière oblique à partir de la chambre, à la fois radialement vers l'extérieur de cette chambre et axialement à l'opposé de la buse, en vue de dessus, et les moyens d'évacuation (8) prolongent ladite chambre commune vers l'aval, au-delà de la jonction entre la branche de diffusion et la chambre commune. L'invention confère une grande compacité au dispositif de l'invention, puisque le dimensionnement de ce dernier tient compte du fait que les fines gouttes sont générées sur une faible distance axiale en sortie de la buse. Par ailleurs, le dispositif conforme à l'invention peut avantageusement être mis en service, même en l'absence de moyens de ventilation.
Abstract:
A system for cooling a space in a vehicle comprises a sorption wheel (4), at least one heat exchanger (8), at least a first humidifier unit (10) and at least one fuel cell (6), wherein the sorption wheel (4) is adapted for drying ambient air (16) and for conveying dried process air (18) to the downstream heat exchanger (8) and the heat exchanger (8) is adapted for cooling process air (18), with the heat exchanger (8) being connected to the first humidifier unit (10) for humidifying cooled process air (20), and wherein the fuel cell (6) is connected to the sorption wheel (4) and adapted for making available fuel cell exhaust air (32) for regenerating the sorption wheel (4) and water (22) to be introduced into the first humidifier unit (10). Since the utilization of fuel cells is increasingly considered in modern vehicles and, in particular, commercial aircraft, the system according to the invention makes it possible to realize a symbiotic relationship between already installed fuel cells and cooling systems in vehicles, in which the further use of the waste products heat and humidity leads to fuel savings. In addition, an evaporative cooling method is presented, in which a fuel cell serves for supplying heat and water.
