Mechanical compression heat pump was simulated by a chemical process simulation software-Aspen Plus, and the temperature rise, superheating and supercooling degree, selection of working medium and the application of multistage pump were studied.The research results show that, the maximum temperature of single stage compression heat pump is 45 ℃. The optimal degree of superheat is 5 ℃. the optimum working fluid is R152a when the condensing temperature arranges from 60 ℃ to 80 ℃, while the comprehensive properties of R143 or R123 is the best when the temperature range is from 80 to 110 or 110 to 160, respectively. The comprehensive performance of cascade heat pump is better than other forms of multistage pump. The maximum temperature rise of multistage pump is limited by working fluids. Currently, the maximum temperature rise is up to 115 ℃.
