Heating experiment system of solar energy and geothermal-source heat pump for office buildings in Shanghai was designed and built. Six operation modes of automatic switching are proposed for efficient and stable operation and the corresponding control strategy is designed too. Six operation modes are solar direct heating system, solar heat pump heating system, GRHP combined solar energy heating system, GRHP heating system and heat storage in outdoor soil system.
Keywords. solar energy; geothermal energy; operation mode; control strategy; GRHP
