That is, the electric heating assembly 100, the water storage separation assembly 200, the centrifugal pump 300, and the user equipment (e.g., several dryers, ironers, etc.) are assembled. It should be noted that, after starting up, the centrifugal pump 300 pumps water into the electric heating assembly 100, the water is connected in series to each heating element 101 to fill all the spiral pipes with water, and then the centrifugal pump 300 pumps the water until the whole closed circulation system is filled with water.
Specifically, water storage separation subassembly 200 one end is connected with user equipment A, and the other end is connected with centrifugal pump 300, and centrifugal pump 300's the other end is connected with electric heating assembly 100, and user equipment A's the other end is connected with electric heating assembly 100. The water in the water storage tank 201 is added to 50% of the capacity of the water storage tank 201 through the water inlet 201a, and the water in the water storage tank 201 is pumped into the heating elements 101 in the electric heating assembly 100 through the centrifugal pump 300, because the number of the heating elements 101 is 9, and after the 9 heating elements 101 are connected in series, the heating element 101 connected in series at the end is connected with the user equipment a.
It should be noted that, when the heating element 101 is connected to a plurality of user equipments, each user equipment is connected in series, so that the temperature of the heated water can be kept balanced, and the occurrence of an over-pressure condition can be avoided. For example, the heating component 101 is connected to a user device a and a user device B, which are implemented in series. In order to make reasonable use of resources, in this embodiment, the gas exhausted from the exhaust port 201c may also be connected to the user equipments, and the user equipments are connected in parallel.
It should be noted that after passing through a whole circulation heating system, after the high-temperature water flows back to the water storage separation assembly 200 through all the devices, the air generated by the film boiling is isolated from the high-temperature water, and the air is evacuated through the exhaust valve, so that the high-temperature water sucked into the electric heating assembly 100 by the centrifugal pump 300 in the secondary circulation process is ensured to be free of air.
