Embodiment Construction

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] This embodiment provides a rapid heating temperature control method for gas heat exchange equipment, such as figure 2 As shown, the method includes:

[0050] S1. Turn on the hot water faucet and set the preset temperature T 设定 ;

[0051] S2. Detect the actual water flow V of the internal waterway of the gas heat exchange equipment 实 and outlet water temperature T 出 ;

[0052] If V 实 ≥ Program startup water flow threshold V 开 , then the gas heat exchange equipment starts to ignite and burn, and record the actual time t of the accumulative ignition and combustion 实 , and according to the target heating te...

Abstract

The invention belongs to the technical field of gas heat exchange equipment, and discloses a rapid heating temperature control method of gas heat exchange equipment. The method comprises the followingsteps: setting a preset temperature T (setting); detecting actual water flow V (actual) and outlet water temperature T (outlet) of the gas heat exchange equipment ; if V (actual) is greater than or equal to a program starting water flow threshold value V (starting), starting the gas heat exchange equipment to be ignited and combusted, recording actual time t (actual) of accumulated ignition combustion at this time, and controlling the opening degree of a gas valve according to the value of difference between T (target) and T (outlet) so as to change fire power, wherein T (target) is equal tothe sum of T (setting) and delta T (target); and if t (actual) is smaller than reset time threshold value t, and T (outlet) is greater than or equal to T (target), controlling the opening degree of the gas valve according to the value of difference between T (setting) and T (outlet) by the gas heat exchange equipment so as to change the fire power to achieve constant-temperature hot water discharging. According to the method, the problem that a large amount of tap water is wasted due to the fact that the heating speed of existing gas heat exchange equipment is low is solved.

Description

technical field [0001] The invention belongs to the technical field of gas heat exchange equipment, and in particular relates to a rapid heating temperature control method of gas heat exchange equipment. Background technique [0002] Gas heat exchange equipment, such as gas water heaters (such as figure 1 ), gas dual-purpose boilers, gas wall-hung boilers, etc., when the user turns on the hot water tap for the first time, tap water flows into the internal waterway of the hot gas heat exchange equipment body. The gas valve of the heat exchange equipment is opened and ignited to heat the tap water to realize heat exchange. At present, the temperature control method in the process of heating tap water is usually, after ignition, according to the preset temperature T set by the user 预设 and the outlet water temperature T at the outlet of the internal waterway 出 The difference between them is used to control the opening of the gas valve to adjust the firepower, so that the outl...
