Abstract

A new absorption/compression heat pump (ABSOCOMP) for space heating and cooling is being developed under the European Joule Programme. The machine uses water-lithium bromide as working pair and produces ice-slurry at triple point conditions when operates in cooling mode. In this study, the potential of the new multicomponent salt mixture water-LiBr+LiI+LiNO3+LiCl (5:1:1:2 by mol) as working pair was evaluated. An analysis of sensitivity was carried out to study the influence of the absorber temperature on the machine performance in terms of the COP and crystallization risk. Results showed that for the new working pair the cycle can operate at an absorber temperature about 12 °C higher than for water-LiBr, with similar COP values.
