Abstract

The invention discloses a CFD simulation and system simulation model combination based airplane cabin environment control method. Mainly, an airplane environment control system simulation model and an airplane cabin heat environment CFD model are subjected to combined simulation to accurately obtain temperature field parameters of all points in an airplane cabin space under the control of an airplane environment control system, wherein the temperature field parameters include a temperature value around personnel taking an airplane under dynamic control regulation, so that the limitation problem in position setting of a temperature sensor in the prior art is solved. By fitting temperature change of a ceiling temperature feedback point with temperature change around the personnel taking the airplane, the temperature around the personnel taking the airplane can be quickly obtained, and the timeliness of control and the accuracy of control effect are improved; and meanwhile, the optimization control is equivalent to the control on the temperature around a human body, so that the heat comfort level of the personnel taking the airplane is improved and the problems of high error of control on a heat environment in an airplane cabin and incapability of ensuring heat comfort of the personnel in the prior art are solved.

Description

technical field [0001] The invention relates to an optimization control method of the cabin air environment under the adjustment of an aircraft environment control system, which belongs to the intersecting field of environment and automatic control. Background technique [0002] The aircraft cabin environment is a special artificial environment. In order to ensure the normal living environment of the passengers and crew in the cabin, a reliable and efficient air conditioning system (ie, the aircraft environmental control system) is essential. While ensuring the safety and health of the personnel in the cabin, the comfort of the personnel is also extremely important, especially during medium and long-distance flights. In addition, on the premise of ensuring the comfort of passengers and crew, it is also of great significance to reduce the energy consumption of the aircraft environmental control system. [0003] At present, the cabin thermal environment of a general airliner ...
