A method for controlling a water heater system

Abstract

The invention discloses a control method for a water heater system, which comprises a proportional valve, a first on-off valve, a second on-off valve and a burner. The burner includes six fire rows, of which two fire rows form the first fire row assembly. Four fire row components form the second fire row assembly, the proportional valve is connected with the first switch valve and the second switch valve respectively, and the first switch valve is connected with the two fire row components in the first fire row assembly, and the second switch valve is connected with the second switch valve. The four fire rows in the second fire row assembly are connected, and the control method includes: during the power-on process, judge the demand load, and select the first on-off valve and / or the second on-off valve to open according to the demand load; during the temperature control process, judge the demand Load and the current state of the first fire row assembly and / or the second fire row assembly, select the first switching valve and / or the second switch according to the demand load and the current state of the first fire row assembly and / or the second fire row assembly The valve opens and / or closes, which achieves better thermostatic performance.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a control method for a water heater system. Background technique [0002] With the improvement of users' requirements for the quality of life, the use of water heaters and regions continues to increase. Due to the calorific value composition in different regions, the calorific value in different seasons in the same region, and even different gas companies in the same region, the difference in gas calorific value is relatively large, and the working environment of water heaters is more complicated. Factors such as differences in altitude will affect The combustion conditions of the water heater, if the water heater is to cover all areas, the requirements for the hardware and program of the product are very high. It is often necessary to set appropriate combustion parameters in the factory test, which can only meet the needs of most users in most areas, and cannot provide a ...

Problems solved by technology

It is often necessary to set appropriate combustion parameters in the factory test, which can only meet the needs of most users in most areas, and cannot provide a targeted and optimal combustion control scheme for each user, making it easy to burn during the working process of the burner. Problems such as control deviation and poor constant temperature performance
