Summary

Performance parameters of single-stage, double-lift and triple-lift cycles for 1 megawatt industrial-scale absorption heat transformers are calculated by a computer-simulation model. It is concluded that Alkitrate is especially useful for operating at high temperatures, up to 260 deg C, the COPs of Alkitrate cycles are the same or better than those of water-lithium bromide cycles, under the same operating conditions. However, attention should be paid to the solubility problem of Alkitrate at low temperatures, a condensing temperature of the working fluid (i.e. water) below 50 deg C is not recommended.
