By adding the circulating water function, the water stored in the pipeline from the water outlet 5 of the rapid temperature regulating system to the tail end of the water using equipment 17 can be returned to the water tank 1 from the lower port 11 of the water tank 1 through the action of the second circulating water pump 2.

The working principle of the embodiment is as follows: the second temperature sensor detects the temperature at the water outlet 5 and transmits the detected temperature data to the processor of the temperature regulating unit at the stage, when the second temperature sensor detects that the temperature of the water outlet 5 is lower than a preset value, namely the temperature of the water in the pipeline between the water outlet 5 and the water consumption equipment 17 is lower than the preset value, the processor instructs the second circulating water pump 8 and the electromagnetic valve 9 to be opened, under the action of the second circulating water pump 8, the water in the water tank 1 flows out from the water return port 12, and the low-temperature water in the pipeline between the water outlet 5 and the water consumption equipment 17 is conveyed to the lower port 11 of the water tank 1 under the action of the second circulating water pump 8. According to the scheme, high-temperature water is output from the water return port 12 of the water tank 1, and water in a pipeline between the water outlet 5 and the water consumption equipment 17 is circularly preheated by the high-temperature water, so that the zero-cold-water requirement is met.

In some cases, the post-conditioning heat exchanger 16 may be installed near the water usage terminal to effectively compensate for the effects of factors such as heat dissipation in the piping on the water temperature at the water usage terminal.
