Abstract

Aimed at the problem that the conventional absorption heat pumps and compression heat pumps cannot take into account the temperature rise and efficiency, this paper proposes the use of a thermally-coupled hybrid compression-absorption heat pump to achieve high-efficiency and high-temperature output. To meet the demands of different scenarios, a large-temperature-lift cycle and a high-temperature-output cycle are constructed. R245fa and lithium bromide aqueous solution are used as working substance. For output temperature above 100℃, Aspen Plus software is used to establish a mathematical model to predict the cycle performance for calculation. The results show that the optimized coefficient of performance(COP) can be 2.58 or higher when the large-temperature-lift cycle is used to recover the waste heat at 30-40℃. When the high-temperature-output cycle is used to recycle waste heat at 60-70℃, the optimized COP of the cycle can reach 2.83. The cycles proposed are more advantageous than the R245fa compression cycle on temperature lift, output temperature, and efficiency.

Key words： waste heat; heat pump; compression; absorption; recovery; Aspen Plus software
