They will short down the working life of air compressor because they are always started or stopped when we want to make the railway carriage stay in a fixed temperature. now, automatic and intelligent control systems are being applying in bus air - conditions control. in this way, computers control the work of air compressor, the turnaround speed of fan, the open degrees of wind controlled doors and so on
我國大多數客車空調仍然採用簡單的壓縮機開關控制及循環離合控制系統，如：離合器?熱力膨脹閥系統（ cctxv ）和離合器?節流管系統（ ccot ） ，這些控制方式的精度低，當進行恆溫控制時壓縮機處于頻繁的開、停狀態，縮短了壓縮機的工作壽命。In order to study the operation characteristics of hpacdhws, distributed parameter simulation models of the fin heat exchanger and the plate heat exchanger are built up. the compressor model is founded in map - based method, and the thermodynamics expansion value model is built up in force balance method. the dynamic system model is the efficient connection of all component models by laws of equalization of mass, momentum and energy
為了研究hpacdhws的運行特性，本文利用分佈參數法分別建立了翅片管換熱器和板式換熱器的動態數學模型，採用圖形法和力平衡法分別建立了壓縮機和熱力膨脹閥的集總參數計算數學模型，並基於質量、動量和能量守恆定律等約束條件，建立了hpacdhws的動態模擬模型。
