AI Technical Summary

Technical Problem

Existing heater load control methods are subject to fluctuations due to ambient conditions affecting fan speed and have limited sensor measurement ranges, leading to inaccurate and unreliable power modulation.

Method used

Implement a sensor to directly measure combustion air mass flow, combined with a parameter to infer fan speed, using a transition function for smooth transitions across sensor measurement limits, ensuring precise load control independent of ambient conditions.

Benefits of technology

Enables robust and precise heater load control across the entire modulation range without structural changes, preventing discontinuities and ensuring safe operation.

Abstract

A method for operating a heater (1) is proposed. The heater (1) has at least one sensor (17), the signal (24) of which allows a direct conclusion to be drawn about the supplied mass flow Ṁ combustion air, with a measuring range, and a fan (2). The power of the heater (1) is set within the measuring range of the sensor (17) using the signal (24) of the sensor (17), and outside the measuring range of the sensor (17) using a detected parameter which allows a conclusion to be drawn about the speed D of the fan (2). In addition, a heater (1), a control and regulating device (7), and a computer program are proposed.
