Power control method for fuel gas heating water heater

Abstract

The invention discloses a power control method of a gas-fired heating water heater, which includes setting the maximum power of hot water and the maximum power of heating; The heating water heater is controlled. On the basis of not changing the hardware equipment of the existing gas-fired heating water heater, the present invention separately sets the maximum power of hot water and the maximum power of heating and independently controls the supply of hot water and heating, and combines the segmental combustion technology to achieve heating When working, the control power is low, ensuring the working performance of the gas heating water heater; when supplying hot water, the control power is high, and the working curve is expanded, so that the gas heating water heater can provide greater water flow and higher water temperature; the present invention It can make full use of the equipment performance of the gas heating water heater, reduce the hardware configuration and energy consumption of the gas heating water heater on the basis of meeting the user's heating and hot water supply, and save energy and reduce emissions.

Description

technical field [0001] The invention specifically relates to a power control method of a gas heating water heater. Background technique [0002] With the development of economy and technology and the improvement of people's living standards, household heating has become one of the choices of more and more urban residents. Gas heating water heaters have become one of the first-selected equipment for domestic heating due to their advantages of being able to supply domestic hot water and heating hot water at the same time. [0003] A power range is set when the existing gas heating water heater leaves the factory, and its output power is all within this range regardless of the heating state or the hot water state. However, in the selection process of gas heating water heaters, in most cases, the hot water power is greater than the heating power. If the heating power is used as the standard, it cannot meet the demand for large flow of comfortable hot water, especially in winte...

AI Technical Summary

Problems solved by technology

The maximum hot water power is used as a reference for model selection, and the hot water needs to be used for a short time, so the water heater works at a low power state for a long time, resulting in serious performance of the burner, heat exchanger and other components of the gas heating water heater. excess

Especially with the promotion and popularization of energy-saving buildings, the heating power is decreasing; while users pursue a hot water experience with large flow and high comfort, the power of hot water is increasing, and the situation of low heating power and high hot water power is increasing. It also leads to the aggravation of excess performance of gas heating water heaters
