Cabin circumstance control system used for passenger plane

Abstract

The cabin environment controlling system for air bus includes the following assemblies: a frequency conversion motor, a supercharger, a reclaiming heat exchanger, an air bleeding unit A, a water spraying pre-cooler, a secondary heat exchanger, an evaporating cycle refrigerating unit, a mixing chamber, a purifying filter, a cabin and an air bleeding unit B. All the assemblies are connected through pipeline for air circulation. The system has motor driven supercharger to compress air for increasing pressure in the cabin, evaporating cycle refrigerating unit to cool air to the cabin, and independent air bleeding fan to ensure high work efficiency and low noise. The present invention provides comfortable cabin environment for air bus in different flying states.

Description

technical field [0001] The invention relates to an environment control system, in particular to a cockpit environment dehumidification, refrigeration and ventilation control system applied to passenger aircraft. Background technique [0002] The development of the traditional mainline airliner environmental control system has been in many forms, but the core refrigeration part adopts the air cooling method of turbo expansion, that is, the high-pressure air is expanded by the turbo to do work, and its internal energy is converted into kinetic energy, so that the temperature is reduced to meet the air cooling requirements. adjustment requirements. Among them, the supercharging air source of the Boeing 787 is obtained by supercharging the ram air outside the machine through a motor-driven supercharger, and the rest are all medium-pressure or high-pressure supercharging air sources from the engine compressor. Since the pressurized air source from the engine compressor is easily...
