Description
Technical field
The present invention relates to water heaters and wall-hung boiler technical field, and in particular to gas heater and the adaptive flue of wall-hung boiler
The control method of the adaptive flue pressure change of the control method and wall-hung boiler of pressure change.
Background technique
Gas heater or wall-hung boiler have become the heating equipment of family's indispensability, are widely used.And with height
Layer house is more and more, and the gas heater or wall-hung boiler of family are typically mounted on living balcony, gas heater or wall hanging
Furnace is influenced by floor wind pressure also increasing in use.
Existing gas heater or wall-hung boiler the general mood proportion in course of normal operation be it is fixed, because extraneous wind pressure is big or
Rotation speed of fan is not provided with compensation when flue blockage, therefore, causes when external wind presses through big, downdraught or flue blocks
The problems such as efficiency of combustion is relatively low, midway is flame-out, and flame is excessive, cause user not to be available water heater or wall hanging in certain periods
Furnace reduces gas heater or wall-hung boiler adaptability.
Summary of the invention
To solve the above-mentioned problems, the purpose of the present invention is to provide gas heaters and the adaptive flue pressure of wall-hung boiler
The control method of variation is solved using gas heater or wall-hung boiler in the process because flue blockage or extraneous wind pressure are big, quickly
It rebuilds new general mood matching parameter to compensate rotation speed of fan, realizes that machine works normally.
In order to achieve the goal above, the technical solution adopted by the present invention is that:
The control method of gas heater and the adaptive flue pressure change of wall-hung boiler, comprising the following steps:
S1. start gas heater or wall-hung boiler is worked normally；
S2. judge the actual speed of the blower of the gas heater or wall-hung boiler and the size relation of theoretical rotational speed, institute
State wind of the theoretical rotational speed of blower for the flue external pressure of the gas heater or wall-hung boiler when equal with flue internal pressure
Machine revolving speed, the flue external pressure and flue internal pressure that the actual speed of the blower is the gas heater or wall-hung boiler are not
Rotation speed of fan when equal；
S3. according to the judging result of step S2, the rotation speed of fan and general mood for adjusting the gas heater or wall-hung boiler are matched
Than operating normally the gas heater or wall-hung boiler.
When gas heater or wall-hung boiler are in normal combustion, if flue external pressure is greater than flue internal pressure or flue
Blocking, main controller real-time monitoring blower actual speed and within the scope of preset rotation speed, corresponding to increase wind velocity gradient, main control automatic
It calculates new general mood to match, realizes that machine works normally.Flue inside and outside pressure can be detected by pressure sensor, and signal analysis is sentenced
Disconnected and transmission instruction is completed by main controller.
Further, the specific judgement of the step S3 and method of adjustment are as follows: because flue external pressure is greater than inside
Pressure or flue blockage may the problems such as efficiency of combustion is relatively low, midway is flame-out and flame is excessive, therefore in order to realize machine just
Often work, avoids the above risk, and rotation speed of fan and general mood proportion are done and be adaptively adjusted as follows:
If practical rotation speed of fan is greater than theoretical rotation speed of fan and meets practical rotation speed of fan in 2850r/min and 3000r/
When between min, adjustment rotation speed of fan is 3500r/min or more, and readjusts general mood proportion, increases general mood proportion by theoretical value
20%；
If practical rotation speed of fan is greater than theoretical rotation speed of fan and meets practical rotation speed of fan in 2550r/min and 2850r/
When between min, adjustment rotation speed of fan is 3400r/min or more, and readjusts general mood proportion, increases general mood proportion by theoretical value
15%；
If practical rotation speed of fan is greater than theoretical rotation speed of fan and meets practical rotation speed of fan in 2350r/min and 2550r/
When between min, adjustment rotation speed of fan is 3250r/min or more, and readjusts general mood proportion, increases general mood proportion by theoretical value
10%；
If practical rotation speed of fan is greater than theoretical rotation speed of fan and meets practical rotation speed of fan in 2200r/min and 2350r/
When between min, adjustment rotation speed of fan is 3000r/min or more, and readjusts general mood proportion, increases general mood proportion by theoretical value
5%.
Further, when outdoor boundary wind-force is excessive, when being temporarily not suitable for using the gas heater or wall-hung boiler,
When exactly practical rotation speed of fan is greater than theoretical rotation speed of fan and meets practical rotation speed of fan greater than 3100r/min, user is prompted not
The gas heater or wall-hung boiler can be used, shows fault code.
Further, if the gas heater or wall-hung boiler are just when practical rotation speed of fan is less than theoretical rotation speed of fan
Often work indicates the unplugged state of flue.
Beneficial effects of the present invention:
Compared with prior art, method of the invention can needle gas heater or wall-hung boiler when in use, to extraneous wind pressure
The problems such as caused efficiency of combustion is relatively low when blocking for excessive, downdraught or flue, stops working halfway, and flame is excessive, quickly
It rebuilds new general mood matching parameter to compensate rotation speed of fan, improves rotation speed of fan, realize that machine works normally, avoid high level
When user uses gas heater or wall-hung boiler, because of external wind buckling, cause gas heater or wall-hung boiler efficiency of combustion inclined
Problem low, that midway is flame-out and flame is excessive improves its efficiency of combustion while protecting gas heater or wall-hung boiler, saves
The energy is also saved for user with gas cost.
