MODELLING OF SOLID SORPTION CHEMICAL HEAT PUMPS AND REFRIGERATION SYSTEMS

摘要

Recent advances in the mathematical modelling of ammonia-chloride salt chemical heat pumps(CHPs)have been presented in the paper.Basic concepts(e.g.,shrinking core approach or reaction kinetics)were described.Approaches used by various researches have been described in detail.Most important simplifying assumptions and calculation methods were reviewed and compared.Thermodynamic approach to the modelling of the reactor has been presented.Balance equations of the reactor were solved for two different systems(chemisorption ice-maker and heat pump for hot water)were calculated and discussed.Correlations between technical parameters of the system as well as interrelations between COP and equilibrium drop for CaCl_2 have been analyzed.
