对ＨＦＣ１３４ａ和ＣＦＣ１２水平管内流动沸腾换热进行了实验研究．在实验工况范围内，ＨＦＣ１３４ａ比ＣＦＣ１２的沸腾换热系数高３２％～４３％；流量对ＨＦＣ１３４ａ与ＣＦＣ１２水平管内流动沸腾换热系数之比的影响较大，干度和热流密度对其影响相对较小
Experimental study on the flow boiling heat transfer in HFC-134a and CFC-12 horizontal tubes was carried out. In the experimental conditions, HFC 134a is 32% -43% higher than the boiling heat transfer coefficient of CFC-12; the influence of flow rate on the ratio of boiling boiling heat transfer coefficient in HFC-134a and CFC-12 horizontal tubes is larger, Degree and heat flux density of its impact is relatively small
