The pipeline is totally closed, water does not flow in the pipeline, 1/10 with the common area is arranged in the heating area, and the super-energy pipe does not scale because the heating area is high and the water tank is circulated quickly.

The heat energy conversion device is a universal solar energy conversion device, and has the functions of electric auxiliary heating, overtemperature protection, water temperature control and the like, and can limit the water temperature not to exceed 85 ℃. When the water tank is operated, when the return water temperature of the input tail end heat supply system reaches the heating requirement, the circulating water pump enters an intermittent operation mode, heat collection of the solar heat collection system continues to store heat in the water tank, and heat energy is utilized in a delayed mode. The capacity of the heat storage water tank and the total capacity of the heat collection system water tank are determined according to the heating building area and by combining the energy-saving condition of the house building, and the total capacity can be determined by multiplying the heating building area by (4-5) L/m into 5 systems, wherein the bearing pressure of the 5 systems is not less than 0.05 MPa.

When the solar energy heat collection system enters a heating period, the system enters a heating mode to operate, and after the heating period is finished, the system can operate in a domestic hot water supply mode, so that the solar energy heat collection system operates all the year round. And uploading data such as the heat collection temperature of a solar water tank of the system, the return water temperature of a tail end heat supply system, the electric auxiliary heating state and the like to a background. The heating unit adopts the principle of solar heat collection priority design, namely when the temperature Tx of the solar water tank is higher than the set temperature Ts, the solar heating mode is started, the circulating water pump of the whole heating system operates to ensure that the indoor temperature meets the heating requirement, when the return water temperature Th is lower than or equal to Ts, the intelligent control system cuts off the circulation of the solar heat collection system, the system enters the electric auxiliary heating mode, and the circulating water pump of the tail-end heating system operates.

The heating process of the heating machine is as follows: when the solar heat collection temperature meets the heating requirement, the heating system enters a large circulation mode, and the circulating water pump conveys high-temperature water (the upper temperature value and the lower temperature value of the set water temperature) in the solar energy to the tail end heating system in the room to supply heat for the room. The heat supply process of the electric auxiliary heating system comprises the following steps: when the solar heat collection temperature does not meet the requirement of the required heating temperature, the heating system enters a small circulation mode, and the circulating water pump conveys the high-temperature water (the upper temperature value and the lower temperature value of the set water temperature) subjected to electric auxiliary heating to the tail end heating system in the room to supply heat for the room and meet the heating requirement.

During water replenishing, the water replenishing icon flickers, and water replenishing is automatically stopped when the water is full. 4.4 when the water temperature of the tail end heating system in the energy-saving mode 7 reaches a set upper limit, the intelligent electric auxiliary heating stops working; when the water temperature is lower than the lower limit of the set value, the intelligent electric auxiliary heating works again, and the indoor temperature is ensured to reach the required standard by continuous heating.
