| titleOfInvention | A rotatable mid-deep coaxial tube ground source heat pump heating system |
| abstract | The utility model relates to a rotatable mid-deep coaxial tube ground source heat pump heating system, which comprises a rotatable mid-deep coaxial tube system, a circulating pump, a heat pump unit and a heating area. The system has two sets of independent circulation, the first set is the geothermal water circulation, the geothermal system is connected to the first circulating pump to deliver high-temperature geothermal water to the heat pump unit, and the heat pump heats the heating water temperature to a certain temperature through the geothermal water according to the temperature required for heating. The low-temperature geothermal water is returned to the geothermal system; the second set is the heating water circulation. After the heating water is initially heated by the heat pump unit, it is assisted by the solar collector or directly supplied to the heating area according to its temperature. The low-temperature heating water flowing out of the heating area It is transported to the heat pump unit by the second circulating pump for reheating. The rotatable inner tube drives the rotation of the external helical fins to enhance the heat exchange efficiency of the system by using turbulent flow; the new vacuum inner tube improves the service life and heat retention coefficient of the inner tube; the double circulation ensures the stability of the heating system . |
