In this study, we conducted an experimental study on heat transfer and pressure drop in a small-diameter tube with an outside diameter of 4.00 mm using R32 (which is one of the new-generation candidates for alternative low-GWP refrigerants) and R 410A (which is currently used in household air-conditioning systems). Furthermore we conducted thesame experimental study using pure R152a and R32+R152a refrigerant mixtures, and it was made clear that pressure drop and heat transfer characteristics. Also we proposed that the empirical correlation of heat transfer coefficient and pressure drop for equipment design can be applied for heat exchangers using the next generation refrigerants.

在这项研究中，我们对外径为4.00 mm的小直径管内的换热和压降进行了实验研究，分别使用R32(新一代低全球升温潜能值替代制冷剂之一)和R410A(目前用于家用空调系统)。在此基础上，对纯R152a和R32+R152a混合工质进行了相同的实验研究，得到了R152a和R32+R152a混合工质的压降和换热特性。提出了换热系数与压降的经验关联式可以应用于使用新一代制冷剂的换热器。
