摘　　要：针对空气源热泵在低温环境下的低效问题与太阳能系统因依赖于天气状况而呈现的不稳定性等问题,提出了一种由太阳能水集热器、太阳能空气集热器、水源热泵和空气源热泵等4种装置组成的复合供暖、供热水系统,并根据日间与夜间的不同的气候条件,提出了5种运行模式。建立了系统的仿真模型,对系统在整个供暖季的运行仿真表明:该系统能够应对严寒天气并正常高效运转,在全供暖季的平均能效为4.21,各种工作模式的平均能效均在3以上,月平均能效为4~6。Aiming at the low efficiency of the air-source heat pump in cold environment,and the instability of solar system's performance due to the weather,a system for heat and hot water supply is proposed,which combines solar air collector,solar water collector,air-source heat pump,and water-source heat pump.For this system,5 operation modes are designed to deal with the different climatic conditions during the day and night.Then the simulation model of the system is established.The simulation results in the whole heating season shows that the system is able to operate efficiently even in severe cold conditions.The annual average COP of the system in the whole heating season is 4.21,the monthly average COP of each mode is greater than 3,while the monthly average COP varies from 4 to 6.
