摘　　要：传统换热技术在实际应用中的换热量较低,且换热能耗较高,导致换热效果不佳,因此提出换热站大温差吸收式换热技术研究。根据实际需求提出假设,建立数学模型,并搭建换热结构,通过在换热回路中串联吸收式热泵,实现一次水与二次水大温差的形成,通过吸收式传递与换热,将大温差形成的有用能转换为换热机组驱动能,从而实现换热。大温差吸收式换热技术的换热量较高,且换热能力较低,具有良好的大温差吸收式换热效果。The traditional heat exchange technology has low heat exchange and high heat exchange energy consumption in practical applications,the heat exchange effect produced is not good,so the research on absorption heat exchange technology with large temperature difference in heat exchange station is proposed.Assumptions are put forward according to actual needs,mathematical models are established,and heat exchange structures are built.By connecting absorption heat pumps in series in the heat exchange loop,large temperature difference between primary water and secondary water is formed.By absorption transfer and heat exchange,the useful energy formed by large temperature difference is converted into the driving energy of the heat exchanger set,so as to achieve heat exchange.The absorption heat exchange technology with large temperature difference has high heat exchange capacity and low heat exchange capacity,and has good absorption heat exchange effect with large temperature difference.
