detailed description

In order to further understand the invention content, characteristics and effects of the present utility model, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

Please refer to Figure 1, an energy-saving domestic hot water system suitable for centralized bathrooms, including a heating module 2 and a water module 3, the water module 3 includes a water storage tank 4 and terminal water equipment 6, the water storage tank The outlet of 4 is connected to the inlet of the terminal water use equipment 6 through the outlet pipe of the hot water storage tank, and the inlet of the hot water storage tank 4 is connected to the outlet of the heating module 2. The system also includes a sewage heat exchanger 1 and Filter module 7, the secondary side outlet of the sewage heat exchanger 1 is connected to the inlet of the heating module 2; the filter module 7 includes a floor drain 8 and a decontamination device 9, the inlet of the floor drain 8 is connected to the end The outlet of the water equipment 6 is connected through a drain, the outlet of the floor drain 8 is connected with the inlet of the decontamination device 9, and the outlet of the decontamination device 9 is connected with the primary side inlet of the sewage heat exchanger 1, so The primary side outlet of the sewage heat exchanger 9 is connected to the municipal sewage pipeline, and the secondary side inlet of the sewage heat exchanger 1 is connected to the municipal tap water pipeline.

In this embodiment, there are two decontamination devices 9 arranged in parallel. When one of the decontamination devices 9 is closed due to maintenance, the other one is turned on, so as to ensure the continuous operation of the system. In order to ensure that the water outlet has a sufficient speed, a water pump 5 is provided on the water outlet pipe of the heat storage tank.

Considering the benefits generated by heat recovery and reducing the initial investment of the system, it is recommended that the design heat transfer temperature difference between the outlet water temperature on the primary side of sewage heat exchanger 1 and the inlet water temperature on the secondary side be between 3 and 5 °C.

The above-mentioned heating module 2 is used for further heating of domestic hot water to reach the designed water supply temperature of the domestic hot water system. The heating types of the heating module 2 include gas hot water boilers, solar water heaters, electric hot water boilers and heat pump units.

Working principle of the utility model:

The municipal tap water first absorbs the waste heat in the system discharge water in the sewage heat exchanger 1, then is sent to the heating module 2 for heating, and finally is sent to the hot water storage tank 4 for storage. The domestic hot water in the hot water storage tank 4 is transported by the water pump 5 to the terminal water use equipment 6 for utilization, and the discharged water after utilization is collected into the floor drain 8 through the drainage ditch, and then flows to the decontamination device 9 through the drainage pipe for filtration. The filtered discharge water enters the primary side of the sewage heat exchanger 1 to exchange heat with the municipal tap water on the secondary side of the sewage heat exchanger 1, and the discharged water after heat exchange is directly discharged into the municipal sewage pipe.

Although the preferred embodiment of the utility model has been described above in conjunction with the accompanying drawings, the utility model is not limited to the above-mentioned specific implementation, and the above-mentioned specific implementation is only illustrative and not restrictive.
