本申请要求广东美的暖通设备有限公司、美的集团股份有限公司于2018年06月19日提交的、申请名称为“燃气炉的控制方法、控制***及燃气炉”的、中国专利申请号为“201810628331.8”的优先权。This application requires that Guangdong Midea HVAC Equipment Co., Ltd. and Midea Group Co., Ltd., which have been filed on June 19, 2018, and whose application name is "Gas Furnace Control Method, Control System and Gas Furnace," and whose Chinese patent application number is " 201810628331.8 "priority.

When the burning carbon dioxide CO2 is closer to the theoretical value, the smaller the flue gas loss, the higher the energy efficiency. However, the higher the CO2, the smaller the excess air and the greater the probability of incomplete combustion. In addition, gas stoves and other products are usually installed in the basement, and the flue gas needs to be discharged to the outside. Therefore, a longer smoke exhaust pipe needs to be connected. The longer the smoke exhaust pipe, the greater the resistance, resulting in a smaller exhaust fan air flow. Considering the angle, you can't adjust the CO2 too high. Generally, it should be controlled below 8%. Otherwise, the low voltage or the long smoke pipe installed may cause harmful gas to exceed the standard, and there is a hidden safety hazard.

As shown in FIG. 1 and combined with FIG. 3, a method for controlling a gas furnace according to an embodiment of the present application includes the following steps:
S101：检测排烟管出口的实际压力P’。S101: The actual pressure P 'at the outlet of the smoke exhaust pipe is detected.
如图3所示，通过设置在排烟管出口上位置A的压力测试点检测排烟管出口的实 际压力P’。可以通过压力传感器检测位置A的压力，并作为排烟管出口的实际压力P’。As shown in Fig. 3, the actual pressure P 'of the exhaust pipe outlet is detected by a pressure test point provided at a position A on the exhaust pipe outlet. The pressure at position A can be detected by a pressure sensor and used as the actual pressure P 'at the outlet of the smoke exhaust pipe.
S102：获取排烟管的长度压损ΔP
1和排烟风机本身压降ΔP
2。
S102: Obtain the length pressure loss ΔP 1 of the exhaust pipe and the pressure drop ΔP 2 of the exhaust fan itself.
其中，排烟管的长度压损ΔP
1与排烟管的长度和管径相关，即：不同长度的排烟管、不同管径的排烟管，其压损(压力损失)不同，因此，在排烟管的长度、管径等参数确定后，可以得到排烟管的长度压损ΔP
1。
The pressure loss ΔP 1 of the length of the smoke exhaust pipe is related to the length and diameter of the smoke exhaust pipe, that is, the pressure loss (pressure loss) of the smoke exhaust pipe of different lengths and smoke pipes of different pipe diameters is different. Therefore, After the parameters such as the length and diameter of the smoke exhaust pipe are determined, the length pressure loss ΔP 1 of the smoke exhaust pipe can be obtained.
排烟风机本身压降ΔP
2由排烟风机的风压曲线确定，例如：不同的电压下，排烟风机本身压降ΔP
2不同，因此，可以根据风压曲线得到当前的排烟风机本身压降ΔP
2。
Exhaust fan itself is determined by the pressure drop [Delta] P 2 curve exhaust fan, for example: different voltages, different exhaust fan itself, the pressure drop [Delta] P 2, and therefore, the current can be obtained according to the press itself exhaust fan pressure curve Drop ΔP 2 .
S103：根据燃气阀正常输入负荷Q、排烟管出口的实际压力P’、排烟管的长度压损ΔP
1和排烟风机本身压降ΔP
2得到燃气阀实际输入负荷Q’。
S103: The actual input load Q 'of the gas valve is obtained according to the normal input load Q of the gas valve, the actual pressure P' of the exhaust pipe outlet, the length pressure loss ΔP 1 of the exhaust pipe, and the pressure drop ΔP 2 of the exhaust fan itself.
作为一个具体的示例，首先根据排烟管出口的实际压力P’、排烟管的长度压损ΔP
1和排烟风机本身压降ΔP
2得到压损率N，然后根据压损系数a、压损率N和燃气阀正常输入负荷Q确定燃气阀实际输入负荷Q’。
As a specific example, the pressure loss rate N is first obtained according to the actual pressure P 'of the exhaust pipe outlet, the length pressure loss ΔP 1 of the smoke exhaust pipe, and the pressure drop ΔP 2 of the exhaust fan itself, and then the pressure loss coefficient The loss rate N and the normal input load Q of the gas valve determine the actual input load Q 'of the gas valve.
进一步地，燃气阀实际输入负荷Q’为压损系数a、压损率N和燃气阀正常输入负荷Q的乘积。Further, the actual input load Q 'of the gas valve is the product of the pressure loss coefficient a, the pressure loss rate N, and the normal input load Q of the gas valve.
具体而言，压损率N＝P’/P，其中，P’＝P-(ΔP
1+ΔP
2)。燃气阀实际输入负荷Q’＝a*Q*N，从而得到燃气阀实际输入负荷Q’。
Specifically, the pressure loss ratio N = P ′ / P, where P ′ = P− (ΔP 1 + ΔP 2 ). The actual input load Q 'of the gas valve is a * Q * N, so that the actual input load Q' of the gas valve is obtained.
其中，压损系数a位于(0，1)之间，压损系数a根据不同设计机型的燃气炉而不同。Among them, the pressure loss coefficient a is between (0, 1), and the pressure loss coefficient a is different according to the gas furnace of different design models.
S104：根据燃气阀实际输入负荷Q’调节燃气阀的开度。S104: Adjust the opening degree of the gas valve according to the actual input load Q 'of the gas valve.
例如：排烟风机风量下降，无法满足大能力的燃气燃烧需求时，根据燃气阀实际输入负荷Q’，燃气阀自动减小燃气输入量，从而保证燃烧氧气充足，燃料燃烧完全。For example, when the air flow of the exhaust fan decreases and it cannot meet the demand for high-capacity gas combustion, the gas valve automatically reduces the gas input according to the actual input load Q 'of the gas valve, thereby ensuring sufficient combustion oxygen and complete fuel combustion.
