Résumé

The performance of a double effect absorption cycle for trifluoroethanol (TFE)-tetraethyleneglycol dimethyether (TEGDME) and methanol-TEGDME can be improved if a compression stage is introduced between the evaporator and the absorber. The COP and primary energy ratio (PER) values in the cooling mode are significantly increased over a wide working range: the cycle can work with temperature lifts of 50 deg C at 5 deg c in the evaporator or it can also be powered by low grade heat. For these conditions COP and PER values are higher than 1 and 0.7 respectively, and the power supplied to the compressor represents up to 15% of the thermal energy supplied to the generator . As it is possible to work at high temperatures lifts, the absorber and condenser can be air cooled.
