Deepen the reform of heating metering and smart heat meters are "on duty"

　The road to reform of heating metering

　Heat metering is based on central heating or district heating. With the purpose of adapting to users' thermal comfort needs, enhancing users' awareness of energy conservation, and protecting the interests of both heating supply and heat users, household metering and charging are achieved through certain heating control technologies, measurement methods, and charging policies.

For a long time, my country’s heating pricing has mostly adopted the heating area charging method. This "package system" heating method has many disadvantages, which is not convenient for users and wastes a lot of money. energy. As the energy shortage problem becomes increasingly apparent, my country has begun to establish a heating metering and charging system.

From the 1999 "Energy Saving Management Regulations for Civil Buildings", household heat measurement technology and devices were included in the regulations for the first time, and heat meters gradually came into work; by 2003, the former Ministry of Construction and other eight The "Guiding Opinions on the Pilot Work of Urban Heating System Reform" jointly issued by ministries and commissions stipulates that welfare heating should be stopped, commercialization and monetization of heat use should be implemented to promote household metering and charging based on heat use, and increase enthusiasm for energy conservation. The wave of heating reform in more than a dozen provinces and dozens of cities across the country has created opportunities for the vigorous development of heat meters.

In 2007, it entered a new stage centered on the reform of heat metering. This stage advocates "pay as much heat as you use". The "package fee system" is gradually withdrawing from the market. At the same time, in order to further standardize heating measurement standards, various heating regions in the north have issued a series of documents and regulations in terms of policies, systems, and technical regulations. In addition, corresponding documents have been issued for heat metering-related equipment, and multiple measures have been taken to promote the development of the heat metering industry.

　What is the significance of heating metering reform?

From a national perspective, it can promote energy conservation and emission reduction. The implementation of charging based on heat metering has mobilized users' enthusiasm for energy-saving behavior, raised the whole society's awareness of building energy conservation, and reduced pollutant emissions.

From the perspective of the people, it improves thermal comfort and reduces heating expenses through energy conservation. Charges based on heat metering are implemented, and users can set different temperatures for different living spaces in different time periods according to their needs.degree, so that heat can be used more effectively and unnecessary waste can be reduced. It can not only meet personalized heat needs, but also reduce heat expenses through energy conservation.

Therefore, our country continues to deepen the reform of heating metering. In recent years, relevant national departments have successively issued a number of regulations or policies related to heating metering. The introduction of relevant national policies has provided strong support for the continued deepening of the reform of heat metering. As a key instrument for implementing heat metering charges, smart heat meters have It will maintain stable development with the deepening implementation of domestic heating metering reform. How much do you know about heat meters?

　How much do you know about heat meters?

A heat meter is an instrument used to measure, calculate and display the value of heat released or absorbed by water flow through the heat exchange system. Heat meters are mainly divided into three categories: mechanical, electromagnetic and ultrasonic based on the measurement principle of flow sensors. Among them, electromagnetic and ultrasonic heat meters belong to the category of smart heat meters. They are composed of flow sensors, temperature sensors and thermal energy totalizers. .

Heat meters have been introduced to China for more than 20 years, which is almost the same time as mobile phones were introduced to China. In 1992, the General Administration of Quality Supervision, Inspection and Quarantine and the China Secretariat of the Legal Metrology Organization translated and published the OTML-R75 recommendation "Thermal Energy Meter" (thermal energy meter is the early name of the heat meter).

From the perspective of development history, the development of heat meters in my country has roughly gone through five stages:

From 1998 to 2002, the first stage China's heat meters have laid their own technical foundation. From 2003 to 2007, in the second stage, China's heat meters experienced severe tests in the process of entering the market and application. From 2008 to 2012, in the third stage, China's heat meters In the rapid development of the table, problems have been further discovered and the direction has gradually been clarified;

From 2013 to 2017, the fourth stage is towards intelligence and networking, providing systematic solutions Solution development, now, with the entry of emerging things such as artificial intelligence, NB-IOT and the Internet of Things, the heat meter has entered the fifth stage of development since 2018 and has maintained a good development trend.

Heating metering road is long and heat meters are developing vigorously

Our country has always been a large energy consumer, so scientific and reasonable solutions The contradiction between rapid social and economic growth and low energy utilization is one of the important issues that our country has been facing for a long time. As an important part of energy consumption, urban heating systemInstalling heating metering devices to charge fees and encouraging users to save energy is one of the important means to improve energy utilization.

Benefiting from the increase in heating area, my country's market demand for heat meters continues to increase, and the market size is growing rapidly. Data shows that the market size of my country's heat meter industry reached 5.75 billion yuan in 2019. In the long run, the national concept of energy conservation, emission reduction, and sustainable development fundamentally guarantees the long-term and stable development of heat meters.

The rise of the Internet of Things and big data provides good technical support for the construction of smart heating networks. However, with the popularization and deepening of the heat metering reform, higher standards have also been put forward for heat metering instrument companies. It is not difficult to see that there is still a long way to go for heat metering, and its related meters and heat meters have also developed accordingly. The future is promising.
