Abstract

The invention provides a method and device for controlling hot water circulation, which are used to solve the problem of heat energy loss caused by unreasonable hot water circulation in the prior art. The method includes: controlling the circulating pump to turn on when the temperature of the water outlet of the water tank satisfies the first preset temperature condition, and turning off the first time when the temperature of the water inlet of the water tank meets the second preset temperature condition; controlling the circulating pump when the temperature of the water inlet of the water tank meets the first preset temperature condition. Turn on when the three preset temperature conditions are met, turn off for the second time when the water inlet temperature of the water tank meets the second preset temperature condition; and control the circulation pump to turn on when the second closing time meets the first preset time condition, The third time is closed during the preset time condition, and the second preset time condition is the time required for hot water to circulate from the water outlet of the water tank to the farthest water point. Adopting the technical scheme of the invention helps to automatically adjust the time interval of the hot water circulation system according to the actual situation of the water pipeline, which not only satisfies the effect of hot water circulation, but also reduces energy loss.

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 currently four commonly used domestic hot water circulation methods: the first manual circulation, that is, the user turns on the water pump power to perform a hot water cycle; the second appointment timing cycle, that is, the controller starts according to the temperature of the hot water pipeline at the appointed time. Stop the circulating water pump; the third circulating method is to set a temperature sensor at the end of the water to detect the water point temperature, and determine whether to turn on the circulating water pump according to the water point temperature; the fourth circulating method is to install a temperature sensor on the return pipe of the water heater. Detect the temperature of the pipeline, and decide whether to turn on the circulating water pump according to the temp...
