Abstract:
In view of different compressor adding ways in the ammonia-water absorption/compression combined refrigeration(AWA/CCR)cycle, combining the Schulz state equation of the ammonia-water solution, the theoretical analysis and calculations on two combination ways, by adding the compressor in the high-pressure area and in the low-pressure area, are conducted, respectively. The effects of several factors, including the evaporation temperature Te, heat-source temperature Th, as well as the cooling water temperature Tw, on the equivalent heat consumption in compression qCW, heat consumption in absorption qG and the system coefficient of performance(COP)are analyzed under the two combination configurations. The results show that the effect of the equivalent heat consumption in compression on the COP is less than that of the heat consumption in absorption. Besides, the compressor set in the high-pressure area uses more energy than that in the low-pressure area. Moreover, the compressor in the low-pressure area is superior to that in the high-pressure area with respect to the COP. Under the given intermediate pressure, there is an optimum heat-source temperature corresponding to the maximum COP of the AWA/CCR cycle.
