D310空调热平衡及回热问题的原因分析及改进

Analyse and improvement for D310 HVAC thermal balance & Reheating Problem

由于该空调设计没有采用水阀控制,曾一度出现热平衡和暖风严重影响空调制冷性能,我们进行热模拟分析、台架试验最终确定改进方案,并于2006年8月份在东风D310系列车实现改进方案。

Because there is no controlling by water valve in the A/C loop,thermal balance and reheating by the heater occurred,after thermal simulation,bench tests,we confirm the solution of improvement,and implement it in DFL D310 trucks after Aug.2006.
