为了在较低的发电温度下获得较低的制冷温度，建立了一种混合氟制冷剂的扩散吸收制冷机。对R23/R134a和R23/R32/R134a两组混合氟化物制冷剂进行了实验研究。以N，N-二甲基甲酰胺(DMF)为吸收剂，氦气为惰性气体。对于含有R23/R134a的DAR，混合工质蒸汽中R23的浓度和氦气量对制冷温度没有明显影响。对于含有R23/R32/R134a的DAR，混合工质蒸汽中R32的最佳浓度和最佳压力均可获得最低制冷温度−28.8 °C(106.9 °C)和极低的−23.7 °C(极低发生温度83.3 °C)，显示了混合氟化物DAR在低温制冷和低品位热能高效利用方面的应用潜力。
A diffusion absorption refrigerator (DAR) operating with mixed fluoride refrigerants was built to obtain low refrigerating temperature at low generating temperature. Two groups of mixed fluoride refrigerants, R23/R134a and R23/R32/R134a, were tested experimentally. The N,N-dimethylformamide (DMF) and helium were used as the absorbent and inert gas, respectively. For the DAR with R23/R134a, the refrigerating temperature was not obviously influenced by the concentration of R23 in the mixed refrigerant vapor or the amounts of helium. For the DAR with R23/R32/R134a, an optimal concentration of R32 in the mixed refrigerant vapor and an optimal pressure were both found to achieve the lowest refrigerating temperature which was −28.8 °C at a generating temperature of 106.9 °C, and a refrigerating temperature of −23.7 °C was obtained at an extraordinarily low generating temperature of 83.3 °C. It showed the promising potentials of DAR operating with mixed fluoride refrigerants in applications of low temperature refrigeration and efficient utilization of the low-grade thermal energy.
