Summary
Ammonia-water absorption-resorption heat pump (ARHP) is a promising technology for efficient use of low-temperature heat for space heating. In this paper, a two-stage balanced ARHP cycle with multiple internal heat recovery is proposed. The objective of this work is to study performance of the novel cycle and stress utilization of low-temperature solar heat for space heating. A mathematical model is built to obtain COP values, heat supply temperature, heat inputs/outputs and solution circulation ratios at different feasible high pressure/medium pressure/low pressure (PH/PM/PL) values. The results showed that the maximum COP of 1.37 and heat supply temperature of 46.1 °C can be obtained when PH/PM/PL is 1.75/1.10/0.375 MPa under given working conditions. Minimum ambient temperature and heat source temperature to drive the cycle are -17.4 °C and 77 °C, respectively, highlighting the potential of integrating the cycle with commonly used non-tracking solar collectors for space heating.
