A cabin temperature control method and system for a manned aircraft

Abstract

The invention discloses a passenger cabin temperature control method and a system for a manned aircraft. The passenger cabin temperature control method comprises the following steps of: acquiring a multi-point passenger cabin sidewall temperature and a multi-point passenger cabin return air temperature; The passenger cabin sidewall temperature is measured by a plurality of sidewall temperature sensors arranged on the passenger cabin sidewall, and the passenger cabin return air temperature is measured by a plurality of return air temperature sensors arranged on the passenger cabin sidewall; Determining an ideal supply air temperature according to a human body thermal neutral temperature model according to the multi-point passenger cabin side wall temperature and the multi-point passenger cabin return air temperature; According to the ideal air supply temperature, the mixing ratio of the cold and hot circuits in the air conditioning pipeline is adjusted to control the cabin temperature.The passenger cabin temperature control method and the passenger cabin temperature control system provided by the invention can improve the passenger satisfaction with the cabin temperature environment.

Description

technical field [0001] The invention relates to the field of cabin temperature control, in particular to a cabin temperature control method and system for a manned aircraft. Background technique [0002] With the development of society, more and more people choose airplanes as a means of transportation for long-distance travel. During the flight, the cabin temperature is controlled by the crew, such as figure 1 As shown, in the existing temperature control system, the air supply temperature is adjusted to a fixed or selected value by the crew. In this system, the engine bleed air 101 flows in two paths: one path is cooled by the environmental control package 102 as The cold path, the other path passes through the control valve 103 which can be controlled by the air supply temperature controller 110 as a hot path; the two paths of bleed air are mixed in the mixing chamber 104 and sent into the passenger cabin 106, and the crew members pass through the temperature setting devi...
