PROBLEM TO BE SOLVED: To provide a control method of a backflow prevention control valve for preventing backflow of low temperature air toward high temperature air in an HVAC module.SOLUTION: An HVAC module 200 includes an air inlet 201, an evaporator 204 located downstream of a blower, a heater 206 located downstream of the evaporator, and a rear mixing area 216 located downstream of the evaporator and the heater. A control valve 290 prevents backflow of low temperature air toward high temperature air by adjusting the pressure of the low temperature air. A backflow prevention control valve of the HVAC module is controlled by a process for reading the pressure and temperature at various places of the HVAC module, a process for setting discharge targets of an air flow rate and the temperature, a process for calculating resistances of the control valve and mixing valves 224a, 224b, a process for determining corresponding positions of the control valve and the mixing valves, and a process for operating the control valve and the mixing valves to the corresponding positions.SELECTED DRAWING: Figure 1

    【課題】HVACモジュールにおいて、低温エアが高温エアに向けて逆流するのを防止する逆流防止制御弁の制御方法を提供する。【解決手段】HVACモジュール200は、エア入口201と、ブロワの下流に位置する蒸発器204と、蒸発器の下流に位置するヒータ206と、蒸発器およびヒータの下流に位置する後部混合領域216と、を有する。制御弁290は、低温エアの圧力を調節することによって、低温エアが高温エアに向けて逆流するのを防止する。HVACモジュールにおける様々な場所での圧力および温度を読み込む工程と、エア流量および温度の排出目標を設定する工程と、制御弁および混合弁224a,224bの抵抗を計算する工程と、対応する制御弁および混合弁の位置を決定する工程と、制御弁および混合弁をそれらの対応する位置まで動作させる工程と、によって、そのようなHVACモジュールの逆流防止制御弁を制御する。【選択図】図1
