Analyses its characteristics from lg p-h and T-s diagrams, and calculates its theoretical and practical COP values. The analysis shows that, compared with conventional electrical water heater, its maximum theoretical COP is 13.4 times over and it is able to reduce about 92.8% of electricity consumption. 【基金】 湖南省杰出中青年专家科技基金资助项目 (编号 :0 1JY2 10 3 )
