Description
Technical field
The present invention relates to fluid heater technical field more particularly to a kind of high power gas heating hot water furnace control systems
And control method.
Background technology
For the bigger conventional gas-heating water heater of maximum power load, the ratio of minimum load and peak load
Can be 0.16, i.e., for the gas-heating water heater that rated load is 42kW, minimum load can reach 7kW, reuse at this time
With the rotation speed of fan and air quantity big load, it will so that the combustion heat-exchange efficiency of combustion gas is declined very big, be unable to fully utilize
The calorific value of combustion gas.
In the prior art, only there are one constant rotational speeds for the AC blower fan that conventional gas-heating water heater is matched, whether greatly
Load condition or Smaller load state, the rotating speed of the wind turbine are all constant on a rotating speed.However in gas-heating water heater
During use, differing, to establish a capital burnt under high-power load.The burning of Smaller load power is used for a long time, it will makes combustion
The long-term work of gas water heater for heating is unable to fully the calorific value using combustion gas in relatively low fuel gas buring heat exchange efficiency, reduces
The integrated operation heat exchange efficiency of gas-heating water heater, and can also because lower in flue gas exhaust gas temperature, generate compared with
More condensed waters influences the long-time service security and stability of gas-heating water heater.
To improve the heat exchange efficiency of gas-heating water heater, industry is interior it has been proposed that using frequency conversion fan come to gas-heating
Water heater is blown.But the use of frequency conversion fan causes the preceding production cost for the period of gas-heating water heater significantly to rise, in addition, by
It is big in the mobility scale of gas-heating water heater live load, there are two kinds of heating, domestic hot-water supply functions, to also lead to frequency conversion
The service life of wind turbine is not grown.Thus, this design does not obtain industry popularization.
Invention content
For problems of the prior art, low, reliable for operation, combustion that it is an object of the present invention to provide failure rates
Burn the ideal high power gas heating hot water furnace control system of heat exchange efficiency.
It is another object of the present invention to provide it is a kind of control it is simple and reliable, be based on above-mentioned high power gas heating hot water
The control method of stove.
To achieve the above objectives, the present invention adopts the following technical scheme that.
A kind of high power gas heating hot water furnace control system, including：Master controller, the combustion being connect with the master controller
Gas proportioning valve and wind turbine, which is characterized in that the wind turbine is only to have high-grade and low-grade Double Speed Fan, the master controller root
The Double Speed Fan is controlled according to the aperture of the gas ratio valve to be operated in high-grade or low grade.
As a further illustration of the above scheme, operation display is connected on the master controller, in the operation
Display is equipped with the display module for being used for showing the Double Speed Fan operational taps.
As a further illustration of the above scheme, wind pressure sensor is connected on the master controller, in the master control
Wind pressure judgment module is integrated in device processed, the wind pressure judgment module is used for judging whether wind pressure value is normal.
As a further illustration of the above scheme, the gas ratio valve is two-part gas ratio valve.
A kind of high power gas water heater for heating control method, which is characterized in that give gas-heating heat using Double Speed Fan
Water stove is blown, and when gas-heating water heater be under the combustion case of big load power section, uses the rotation speed of fan of top grade；Work as combustion
Gas water heater for heating is under the combustion case of Smaller load power section, uses low-grade rotation speed of fan.
As a further illustration of the above scheme, as the M% of the operating load ＞ peak loads of gas-heating water heater,
Judge that the gas-heating water heater is in big load power section, when operating load≤peak load of gas-heating water heater
When M%, judge that the gas-heating water heater is in Smaller load power section；The value range of the M% is 30%-60%.
As a further illustration of the above scheme, a wind pressure value is being set separately just in top grade, the underdrive operating of corresponding wind turbine
Normal range detects the operation wind pressure value of gas-heating water heater using wind pressure sensor；In the gas-heating water heater course of work
In, when the operation wind pressure value detected is fallen in wind pressure normal range (NR), judgement gas-heating water heater normal work works as detection
To operation wind pressure value fall outside wind pressure normal range (NR) when, judge gas-heating water heater abnormal work.
As a further illustration of the above scheme, when judging gas-heating water heater abnormal work, alarm signal is sent out.
As a further illustration of the above scheme, in the gas-heating water heater course of work, it is aobvious using operation display
Show the operational taps of Double Speed Fan.
As a further illustration of the above scheme, widening the negative of gas-heating water heater in conjunction with two-part gas ratio valve
Lotus adjustable range.
The beneficial effects of the invention are as follows：
One, adapt to the size burning load of gas-heating water heater using high and low two grades of wind turbine wind speed, so as to so that
Gas-heating water heater can also have higher combustion heat-exchange efficiency when small-power load section is run, and improve gas-heating hot water
The integrated operation heat exchange efficiency of stove, embodies the effect of energy-saving and emission-reduction, while enhancing the long-time service safety of gas-heating water heater
Stability.Meanwhile failure rate is low, reliable for operation, great industry application value.
Two, using the gas-heating water heater after Double Speed Fan, in Smaller load, because reducing the suction of additional air
Enter, improve smoke evacuation flue-gas temperature, reduces because flue gas condensing water condensation corrodes the risk of machine, while improving gas-heating
The smoke evacuation flue gas that water heater burns under from the vaporous condition of flame is horizontal, improves flue gas emission level.
Three, in conjunction with staged burners and Double Speed Fan, the combustion power load for effectively improving gas-heating water heater is applicable in
Range enhances the long-time service security and stability of gas-heating water heater.
