✦ Synopsis

In the present paper, the additives 1-octanol and 2-ethyl-1-hexanol, have been used for the first time in a 2 kW single-stage heat transformer installed in the Energy Research Centre of the National University of Mexico utilizing H 2 O/LiBr, operating at absorber temperatures in a range between 70 and 1108C. The results showed that at the same conditions, absorber temperatures increased about 58C by adding 400 ppm of 2-ethyl-1-hexanol to the lithium bromide mixture. Also it was shown that the coefficient of performance increases up to 40% with the same additive.

Absorption heat transformers are devices with the unique capability of raising the temperature of part of a low grade heat source whilst simultaneously rejecting the rest of the heat at a lower temperature. The gross temperature lift that could be attained in the process depends on the characteristi
