Résumé

A solar-ground source heat pump system model according to the climatic conditions in Tianjin is established. A simulation study of the system based on TRNSYS program is carried out, the energy consumption of the system and the ground temperature change are analysed, and the operation strategy is studied with emphasis. An appropriate operation strategy based on the coefficient of performance (COP) of system is selected, i.e. to turn on the solar collection pump as the temperature difference between collector outlet and tank outlet is higher than 15°C, and to turn off the pump until it is under 2°C, and to turn on the solar storage pump when tank outlet temperature is higher than 50°C, and to turn it off until the temperature difference between inlet and outlet of the borehole heat exchanger is under 5°C.
