Compared with the prior art, the utility model has the following advantages:

The electric energy-storage energy-saving hot water supply system of this structure is designed from the perspective of energy conservation and emission reduction, aiming at the problem of energy consumption in the 24-hour hot water supply, an electric energy-storage hot water supply energy-saving system is designed. The so-called electric energy storage, that is, heating water with electricity, and then storing it. The storage heating process is completed during the low power period. At this time, there is almost no electricity and water usage. In the peak period of water consumption, that is, the peak electricity period, the water supply no longer needs energy-consuming heating and is circulated to the hot water system. Its practicability lies in taking advantage of the time difference and electricity fee difference between the valley electricity and the peak point, using the night valley electricity period and low electricity price for heating and energy storage, and the operating cost of the whole system is particularly low. Through calculation, compared with the steam hot water boiler circulation method, the operating cost can be reduced by half.

Furthermore, the system itself is an open loop system. After the temperature of the circulating return water in this system is lowered, the return water is stored in an intermediate water tank. The system is an open system, and the circulating water flows to the intermediate water tank while maintaining a certain pressure. Then, the heating cycle is continued from the water tank and the water supply pump system, and the hot water system is opened by the regulating valve. This design not only saves the whole set of circulating pump, but also makes the system simple. Directly use the water supply pump instead of the circulating pump, and let the return water open and flow back under the condition of ensuring the pressure. The purpose of effective cost control is achieved by saving circulating pumps.

To sum up, it can be said that this hot water supply system has many advantages, and is especially suitable for promotion and application in this field, and its market prospect is very broad.

The working process of the electric energy-storage energy-saving hot water supply system of the embodiment of the present invention is as follows: the electric hot water boiler 2 works during the electric wave valley to heat the water body in it, and the hot water generated after heating acts on the pump group 5 The hot water enters the water separator 4 through the third pipeline 3, and can be supplied to many different heating terminals for use; after the hot water enters the first circulation pipeline 6, it communicates with the second heat exchanger The cold water in the circulation pipeline 11 exchanges heat, and the heat is transferred to the right half of the system; after the cold water enters the water collector 7, it will return to the electric hot water boiler 2 through the second pipeline 9 for heating, and this cycle , and continuously carry out the heat energy generated by the electric hot water boiler 2 when it is working;

The cold water entering the second circulation line 11 through the water pipe network exchanges heat with the hot water in the first circulation line 6 at the plate heat exchanger 8 , and after the heat is obtained, it becomes hot water and is stored in the hot water tank 10 When the hot water heating system needs to use hot water, start the pump group 5 on the hot water pipeline 13 to pump the hot water in the hot water tank 10 to the hot water supply terminal 14 for use.
