Problems solved by technology

Aircraft ground air-conditioning vehicles mostly have one air supply duct. For aircraft ground air-conditioning vehicles where there are multiple air supply ducts and the required air volume of each duct is different, and the adjustment accuracy of air supply air volume is low
In addition, the current air supply fan and air valve are adjusted frequently or start and stop, resulting in unstable air supply parameters, poor user experience, and affecting the life of components

Embodiment

[0061] A method for controlling the air volume of an aircraft ground air conditioner, comprising a fan, an air duct group composed of N air ducts, and an air valve group composed of N air valves.

[0062] Generally speaking, two air ducts are enough for an aircraft. Therefore, in this embodiment, one fan controls two air ducts as an example, and each air duct is provided with a flow sensor and a damper;

[0063] like figure 1 As shown in the system diagram, there are 2 air supply ducts. The outdoor fresh air is sent to the surface cooler for cooling and dehumidification through the fan, and then sent to each air duct after being adjusted by the heater. One flow sensor is installed in each air duct. When user panel 1 or user panel 2 receives the power-on signal, press figure 2 In the start-up control process, the air valve of the corresponding air duct is fully opened to 100%, and the air valve opening signal Von=1 is output.

[0064] If Von1=1 and Von2=1, that is, both damp...

Abstract

The invention discloses an aircraft ground air conditioner air volume control method and system and an air-conditioned vehicle, the air-conditioned vehicle comprises a fan, an air duct set composed of N air ducts and an air valve set composed of N air valves, and the method comprises the following steps that whether the actual flow G meets the condition A or not is judged, if the condition A is met, the frequency f of the fan is increased by f1, and if the condition A is not met, the condition B is judged; whether the actual flow G meets the condition B or not is judged, if the condition B is met, the current fan frequency is kept unchanged, and if the condition B is not met, the condition C is judged; whether the actual flow G meets the condition C or not is judged, and if the actual flow G meets the condition C, the frequency f of the draught fan is reduced by f2; and if the condition C is not met, continuing to judge the condition A. The action frequency of all the components is effectively reduced, the service life of all the components is prolonged, and according to the required air volume of all the air channels, accurate and rapid control is achieved to reach the target value.

Description

technical field [0001] The invention relates to the air volume control of an aircraft, in particular to a method, a system and an air-conditioning vehicle for controlling the air volume of an aircraft ground air conditioner. Background technique [0002] The aircraft ground air conditioning vehicle provides fresh air with suitable temperature, air volume and pressure for the aircraft cabin and equipment, and air volume control is very important. Most of the aircraft ground air conditioners are one air supply duct. For the aircraft ground air conditioners where there are multiple air supply ducts and the demanded air volume of each pipeline is different, the adjustment accuracy of the air supply air volume is low. In addition, the current air supply fans and dampers are frequently adjusted or started and stopped, resulting in unstable air supply parameters, poor user experience, and affecting the life of components. SUMMARY OF THE INVENTION [0003] In order to solve the a...
