The working principle of the utility model:

The heat transfer oil in the heat exchanger 36 is heated by the solar energy collector 31, and the heat transfer oil after the heat radiation conversion and heating of the solar energy collection plate 2 is delivered to the heat exchanger 36 due to the non-stop circulation of the solar heat transfer pipe with the oil pump 4, The heat transfer oil stored in the heat exchanger 36 stores thermal energy, and the heat of the heated heat transfer oil is transferred to the superconducting liquid in the floor heat radiation device 33 through the spiral copper tube 9, and the temperature of the superconducting liquid is 50 degrees Celsius above zero Hot steam can be produced, and the steam temperature can reach more than 120 degrees. Since the pipeline of the floor heat radiation device 33 is always in a closed state, the steam circulates continuously in the pipeline, and the ground heat radiation pipe 23 is continuously heated to achieve the purpose of heating.

Since the heat transfer oil has the excellent performance of slow heat dissipation, high oil temperature, and high thermal efficiency, the heat transfer oil is stored in the heat exchanger 36 for heat energy conversion.

Heat transfer oil heat expansion ball 3, solar heat exchanger expansion ball 10 and oil pipeline expansion ball 18 are arranged on the pipeline, because the heat transfer oil has the characteristics of thermal expansion and cold contraction, the excess volume of oil after heating can automatically enter the thermal expansion ball inside, at night or In continuous cloudy days, after the oil temperature cools down, the oil in the heat-expandable ball will flow back into the pipeline again. In the same way, the effect of the high-temperature steam expansion ball 16 is to prevent the high-temperature steam from thermally expanding and damaging the pipeline.

Since the continuous winter cloudy days cannot guarantee the normal heating and heating demand of the solar heater, the oil temperature in the heat exchanger 36 drops to the point that it cannot normally supply heat to the floor heat radiation device 33, and the oil temperature sensor 12 in the heat exchanger 36 will The temperature information of the heat transfer oil is sent to the intelligent module controller 24, and the intelligent module controller 24 receives the oil temperature lower than the heating temperature, automatically starts the heating device 32, heats the heat transfer oil in the heat exchanger 36, and reaches the floor heat radiation device 33 The heating temperature demand automatically stops heating, and keeps in the constant temperature state in the heat exchanger 36 all the time.

The heat transfer oil in the heat exchanger 36 can be vaporized by heating the high-temperature superconducting liquid in the geothermal radiant tube to above 50 degrees Celsius, and the heating temperature can reach above 120 degrees, which can fully meet the needs of family heating, and keep the heat exchanger 36 at all times. The temperature of the oil inside is not lower than 50 degrees, and the heating is started when the temperature is lower than this temperature.

The heat exchanger 36 shell wraps the polyurethane solar heat exchanger insulation layer 8 for maintaining the oil temperature in the heat exchanger in a heat preservation state for a long time.

The shower system 34 adopts an open pipeline, and the running water is heated by the heating pipe in the heat exchanger 36. Due to the pressure of the running water itself, the heating of the heating pipe is delivered to the shower nozzle 15 and just can take a bath.

The electric heater 17 can also be heated by gas, such as natural gas, biogas or straw gas wall-hung boiler, due to the high operating cost, which has more ideal social and economic benefits.
