Environmental concerns have urged a search for eco-friendly refrigerants in the refrigeration industry to overcome ozone depletion and global warming problems. Therefore, current research emphasizes frictional pressure drop during flow boiling of environment-friendly refrigerants (GWP<150), isobutane, HFC-152a, HFO-1234yf were tested against commonly reported HFC-134a. The data presented here was collected under heat flux-controlled conditions; the test piece was a round tube (1.60 mm diameter). The data collection was performed at 27 and 32°C with mass velocities in 50-500 kg/m²s range. Effects of critical controlling parameters, like heat flux, mass velocity, exit vapor quality, operating pressure and medium, were studied in detail. It was observed that pressure drop increases along with mass velocity increment in the test piece and increases with exit vapor quality increment. The same was noticed to decrease via operating saturation temperature increment. Parametric effects and prediction of assessment methods reported.

环境问题促使在制冷行业中寻求环保型制冷剂，以克服臭氧消耗和全球变暖问题。因此，当前的研究强调环境友好型制冷剂（GWP <150）的沸腾过程中的摩擦压降，已针对常用报道的HFC-134a对异丁烷，HFC-152a，HFO-1234yf进行了测试。此处提供的数据是在受热通量控制的条件下收集的；试件为圆管（直径1.60 mm）。在27和32°C下以50-500 kg / m ^2的质量速度进行数据收集的范围。详细研究了关键控制参数的影响，例如热通量，质量速度，出口蒸汽质量，工作压力和介质。观察到压降随着试件中质量速度的增加而增加，并且随着出口蒸气质量的增加而增加。注意到通过操作饱和温度增加，相同的值降低。报告了参数效应和评估方法的预测。
