Abstract

The invention provides a control method and a device of hot-water circulation, which are used for solving the problem of heat energy loss caused by unreasonable hot-water circulation in the prior art. The method comprises the following steps of controlling a circulating pump to be opened when water outlet temperature of a water tank meets a first preset temperature conduction, and controlling the circulating pump to be closed for the first time when water inlet temperature of the water tank meets a second preset temperature conduction; controlling the circulating pump to be opened when the water inlet temperature of the water tank meets a third preset temperature conduction, and controlling the circulating pump to be closed for the second time when the water inlet temperature of the water tank meets the second preset temperature conduction; controlling the circulating pump to be opened when closed operation time of the second time meets the first preset temperature conduction and controlling the circulating pump to be closed for the third time when the closed operation time of the second time meets the second preset temperature conduction, wherein the second preset temperature conduction is time required by the hot water circulating from the water tank to farthest water using points. By means of the technical scheme, interval of a hot-water circulation system can be automatically adjusted according to actual situation of the water using pipelines, so that effects of hot-water circulation are achieved, and energy loss is reduced.

Description

technical field [0001] The invention belongs to the field of water heaters, and relates to a method and device for controlling hot water circulation. Background technique [0002] There are four commonly used domestic hot water circulation methods: the first manual circulation, that is, the user turns on the power of the water pump to perform a hot water circulation; Stop the circulating water pump; the third circulation method is to set a temperature sensor at the end of the water to detect the temperature of the water point, and decide whether to turn on the circulating water pump according to the temperature of the water point; the fourth circulation method is to set a temperature sensor on the return pipe in the water heater to Detect the temperature of the pipeline, and decide whether to turn on the circulating water pump according to the temperature there. [0003] The disadvantages of the above domestic hot water circulation methods are obvious: the disadvantage of t...
