Secondary alcohol additives for lithium bromide-water absorption refrigeration system
Abstract
Abstract A refrigerant-absorbent solution as a working fluid for use in absorption refrigeration systems that produces a substantial increase in the overall capacity of the refrigeration machine by improving the heat transfer in the absorber, by promoting dropwise condensation of the refrigerant vapor on the exterior surfaces of the condenser tubes and by improving purging of relatively noncondensible gases of the absorption machine. The working fluid comprises water as the refrigerant in combination with lithium bromide as the absorbent to which is added additives such as 4-heptanol, decyl alcohol, 2-phenoxyethanol, nonanol, 3methyl-2-heptanone, methyl octanoate, 3-methyl-2-heptanol, 1heptanol, 1-octanol, 2-hexanol, 2-octanol, 2-methyl-2-hexanol, 2methyl-2-heptanol, 6-methyl-2-heptanol, and 2-heptanol. These additives are supplied to the lithium bromide-water fluid in the range of 50 to 1,000 parts per million on a weight basis of the lithium bromide-water solution.
