The thermodynamic coefficients of absorption refrigeration cycle and type II heat pump cycle are given in this paper. The primary energy efficiency, cooling capacity, heat supply and temperature rise of the system vary with the driving hot water temperature and flow rate, condensing pressure and evaporation pressure, dilute solution concentration And the steam range and load water temperature changes. And analyzes the economic operating conditions under different driving hot water temperatures, the matching relationship between the refrigeration cycle refrigeration capacity and the heat supply of the type II heat pump cycle, and the energy saving effect of the system
