Résumé

The work presents model results of the nontruncated and simple truncated ammonia-water hybrid coabsorbent heat pumping cycles (Staicovici, 2007). The cooling cyles are run for sink temperatures of 12 to 4°C and desorber temperatures of -60 to -5°C. The depleted heat source temperature has been considered to be by 20 to 40°C higher than the sink source. The effectiveness with respect to the pumping and mechanical vapor compression (mvc) work consumption shows values ranging within several to one and two orders of magnitude higher as compared to the single-stage mvc cooling cycles. Concerning the heating cycles, these are run for heat source temperatures of 5, 37 and 70°C. The sink source temperature ranges within -50 to +50°C. The usefully heated fluid temperature resulted in values of 40 to 140°C. The results are very encouraging for use of the hybrid coabsorbent cycles in heat pumping applications with high primary energy savings.
