Summary

Energy and environmental issues have attracted more and more community attentions, and the efficient utilization of energy is particularly important. In practice, plenty of low grade energy has not been rationally used, such as solar energy, geothermal energy and industrial waste heat. A diffusion absorption refrigerator can directly use low grade heat to achieve refrigeration without any electricity input. On the basis status of the diffusion absorption refrigeration both at home and abroad, this paper conducted the performance research of the diffusion absorption refrigeration with mixed fluoride refrigerants. In this work, R32, R134a and the mixture of both were respectively used as the refrigerants, DMF was used as the absorbent and Ar was used as the inert gas. The experimental results indicated that the performance of R32/R134 was better than either of the two pure refrigerants. There was an optimal concentration of R32 in the vapor mixture refrigerants and an optimal heat input to reach the lowest refrigerating temperature.
