The reform of the heat metering and charging system under the vigorous promotion of the government has already been a task that has to be changed and must be completed. How do thermal companies actively adopt effective measures to achieve a significant energy-saving operation of the company through the reform of the heating metering and charging system, so as to achieve a win-win situation for users and enterprises. This is the reason why we introduced the SMECH3000 heating metering energy-saving regulation system.
When the central heating system charges users according to the amount of heat, it must provide the user with room temperature control devices. With the user's room temperature adjustment means, the secondary network will change from the traditional constant flow operation to the variable flow operation, that is, the original points. The quality adjustment mode for changing the flow in stages must be adjusted to the mode of changing the temperature in stages. Therefore, when the central heating system charges according to the user's heat, it must fully consider the adjustment of the operating conditions of the entire thermal network system. After the experience of the thermal network monitoring system operating in the past decade, the Masters era has made every effort to create SMECH3000 energy metering and energy saving control system. , Integrate with our mature STEC2000 thermal network monitoring system to provide centralized heating companies with a comprehensive solution for thermal network operation and regulation in the era of thermal metering.
