Embodiment 1

[0027] Such as figure 1 As shown, a gas water heater control method that can adapt to different altitudes is characterized in that: the water heater is tested according to the set fan speed, and the actual combustion heat is compared with the calculated combustion heat to determine the altitude of the water heater, and Match the fan speed and proportional valve current value corresponding to the optimal heat load state at the altitude, and then store each parameter to make the water heater work according to the corresponding fan speed and proportional valve current value.

[0028] In this embodiment, the calculated combustion heat is calculated according to the water heater's inlet water temperature, set temperature, and water inlet water flow rate; the actual combustion heat is calculated according to the actual water outlet temperature The actual heat of combustion of the gas is obtained.

[0029] In this embodiment, the altitude determination process includes the following...

Embodiment 2

[0033] Such as figure 2 As shown, in this embodiment, the gas water heater control method adaptable to different altitudes specifically includes the following steps: 11) Power on the water heater; 12) The water heater enters the selected mode; 13) The fan follows the default standard of the program 14) Collect the inlet water temperature, outlet water temperature, water flow, fan speed, secondary pressure value, etc. and obtain the calculated combustion heat and actual combustion heat; 15) Based on the calculated combustion heat and actual combustion The heat difference is matched with the pre-stored difference to judge the altitude at this time; 16) According to the altitude, call the pre-stored matching parameters corresponding to the best heat load state at the altitude; 17) Store the best matching parameters ;18) Adjust the fan speed and proportional valve current to make the water heater work according to the best matching parameters.

[0034] In this embodiment, the sp...

Abstract

The invention relates to a method for controlling a gas water heater adaptable to different altitudes. The method is characterized in that the water heater tries to run according to set fan rotating speed, actual combustion heat is compared with calculated combustion heat, altitude at which the water heater is positioned is judged, fan rotating speed corresponding to optimal thermal load state at corresponding altitude is matched with proportional valve current value, parameters are stored, and the water heater is enabled to work according to corresponding fan rotating speed and proportional valve current value. By the above method, the water heater can automatically recognize and judge the altitude at which the water heater is positioned to be matched with corresponding fan rotating speed and proportional valve current value, so that gas utilization rate of the water heater is increased so as to achieve the objectives of saving energy resources and improving gas efficiency. The gas water heater control method is remarkable in effect and suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a gas water heater control method adaptable to different altitudes. Background technique [0002] Gas water heaters on the market do not take into account the altitude of the user's area. Since the boiling point of water in the plateau area is relatively low, and the air pressure value is also small, if the gas water heater adopts the working mode in the plain area, the gas will not be fully combusted and the heating time will be prolonged. This has not only wasted energy, but also delayed the user's use time. [0003] However, the existing high-altitude gas installation generally adopts the method of increasing the wind pressure of the air inlet to speed up the air velocity so that the gas can be fully burned. However, due to the existing gas water heaters, the air intake volume is generally adjusted by changing the fan speed, and the gas intake volume is adjusted by changing the ...
