Problems solved by technology

However, due to the error of the flow sensor, each time only the electric heating end uses hot water, the actual water output detection values ​​of the heating end and the electric heating end are inconsistent, resulting in a misjudgment that the heating end is also using hot water, causing the gas water heater to use the wrong temperature output, it takes a long time to wait for hot water at the heating end

Abstract

The invention discloses a fuel-electricity complementary hot water system and a control method thereof. The fuel-electricity complementary hot water system comprises: a gas water heater with a fuel-heat flow sensor at the fuel-heat water outlet; a cold water outlet pipe; an electric water heater with an electric-heat water outlet An electrothermal flow sensor is provided at the place; the hot water outlet pipe has a water end for hot water. Electric heating hot water outlet pipe; controller, only when the detection value of the heating flow sensor is greater than 0 and the detection value of the heating flow sensor is equal to 0 and the detection value of the heating flow sensor is greater than the detection value of the heating flow sensor plus a predetermined value, control The device judges the water consumption of the hot water end. The fuel-electricity complementary hot water system according to the embodiment of the present invention can eliminate misjudgment caused by the error of the flow sensor, accurately determine the position of the hot water, thereby precisely controlling the output temperature of the gas water heater and realizing rapid hot water output.

Description

technical field [0001] The invention relates to the technical field of electric appliance manufacturing, in particular to a fuel-electricity complementary hot water system and a control method for the fuel-electricity complementary hot water system. Background technique [0002] In the gas-electricity complementary hot water system in the related art, the heating end and the electric heating end are respectively equipped with flow sensors, and by detecting the water output of the heating end and the electric heating end, it is judged whether the heating end and the electric heating end use hot water. However, due to the error of the flow sensor, each time only the electric heating end uses hot water, the actual water output detection values ​​of the heating end and the electric heating end are inconsistent, resulting in a misjudgment that the heating end is also using hot water, causing the gas water heater to use the wrong temperature Output, hot water needs to wait for a l...
