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 refrigerating device, wherein a cycle circuit (20) comprises an expansion device (22), a heat exchanger (30), and a compressor (21) connected in order to each other, a dehumidifying mechanism (60) is provided so as to dehumidify heat-absorbed air taken in through an inlet duct (23), an internal heat exchanger (15) is provided so as to supply the dehumidified heat-absorbed air, after cooling, to the expansion device (22), the heat-absorbed air is expanded in the expansion device (22) causing a temperature to lower, moisture is not condensed at the time of expansion because the heat-absorbed air is dehumidified beforehand, the heat-absorbed air reduced in temperature by expansion flows into the heat exchanger (30) and absorbs heat from indoor air, and then the heat-absorbed air is compressed by the compressor (21) and exhausted to the outside after regenerating a rotor member (61).
Abstract:
An airplane is provided. The airplane includes a pressurized compartment and an environmental control system. The environmental control system includes a compressing device. The compressing device includes a compressor and a turbine. The airplane also includes a first flow of first medium configured to enter the pressurized compartment and a second flow of the first medium configured to enter the turbine.
Abstract:
Systems and methods for providing airflow in an aerospace vehicle are disclosed. A system in accordance with one embodiment includes an aerospace vehicle having an interior volume with a first portion and a second portion. The system can further include an external air supply device positioned to provide supply air to the interior volume at a variable supply flow rate and a recirculation fan configured to move air positioned within the interior volume between the first portion of the interior volume and the second portion of the interior volume. The system can still further include a controller operably coupled to the recirculation fan and configured to vary a rotation speed of the recirculation fan. Variations in the rotation speed of the recirculation fan can be associated with variations in a recirculation flow rate. In selected embodiments, the system can include sensors and/or data link devices operably coupled to the controller.
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).
