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...

Embodiment Construction

[0019] Such as figure 1 Shown is the method flowchart of the present invention: the power control method of this gas heating water heater provided by the present invention comprises the following steps:

[0020] S1. Set two powers on the control panel or operation display of the gas heating water heater, respectively P max1 and P max2 , with P max1 is the maximum power of hot water, in P max2 is the maximum heating power, and P min max2 max1 max ; where P min is the minimum power of the gas heating furnace, P max It is the maximum power available for the gas heating furnace; 1max1 / P max2 <1.5;

[0021] S2. The gas heating water heater controls the gas heating water heater according to the working conditions and the maximum power of hot water and heating set in step S1:

[0022] with [P min , P max2 ] is the power control interval, which controls the heating operation of the gas heating water heater;

[0023] with [P min , P max1 ] is the power control interval, c...
