发动机试验室的通风（空调）热负荷计算

摘要

An equivalent heat transfer model was used to calculate both the convective and radiative heat loads inside an engine test cell. Two different calculation methods, equivalent heat transfer method and heat balance method, were compared and analyzed. Reference heat transfer coefficients were recommended.%为了确定一种常见的水冷式柴油发动机试验室内的通风（空调）热负荷值，采用一种简化的等效体表面换热模型，用以计算出该发动机的对流和辐射换热负荷（简称“等效计算法”）；并对采用不同计算（或估算）方法得出的换热负荷值进行比较分析，推荐了在一定条件下发动机散热系数的经验取值范围，供此类暖通设计者参考。
