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 110°C. The results showed that at the same conditions, absorber temperatures increased about 5°C 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. Copyright © 2005 John Wiley & Sons, Ltd.
