摘要

Economic analyses of some sources of energy, such as biogas, liquefied petroleum gas, ordinary flat plate and evacuated tubular collectors, have been carried out for operating absorption cycles with and without heat recovery absorber. Water-ammonia, NaSCN-NH_3 and LiNO_3-NH_3 have been selected as the working fluids in the cycles. Use of a heat recovery absorber, in addition to the primary absorber in the conventional absorption cycles, improves the system performances by about 20-30% in the H_2O-NH_3 mixture and 33-36% in the NaSCN-NH_3 and LiNO_3-NH_3 mixtures. Consequently, there is a considerable reduction in their energy costs. For the set of operating conditions under study, the cost is reduced by about 25% in the H_2O-NH_3 cycle and by about 30% in the NaSCN and LiNO_3-ammonia cycles.
