  1. The allowable tolerances of interval between band drains, verticality and depth shall be 15cm, not more than 1. 5 % and 50cm respectively

    用電子測深儀測量或抽檢方式檢驗排水板打設的深度，按不小於30 %比例抽檢。
  2. Examinations of steady status and analysis of dynamic experiments have been conducted on band - tube evaporator and parallel - flow condenser using r134a refrigerant. the steady examination show that the model error was under the allowable error, the inlet mass and enthalpy disturb experiments indicate that the subsection model, be good at reflecting the change of parameters of the heat exchanger, accord with the basic principle of thermodynamics theory and the actual work status. hence, the subsection simulation model research has important benefits both on theory and engineering application

    在進行模擬試驗時，以使用r134a作製冷劑的管帶式蒸發器和平行流式冷凝器為對象，完成了穩態模擬計算、試驗和動態模擬分析，穩態計算結果和試驗數據對比表明，其誤差在允許范圍內；進口質量和焓值的擾動試驗結果表明：本文所建的區段式換熱器模擬模型，能很好的反映換熱器性能參數的動態變化，與系統熱動力學理論和冷凝器、蒸發器的實際工作過程基本一致。
