On-off actuator

Basic overview of the on-off time area method

The on-off time area method is based on the water supply time of each household's heating system to allocate the total heating capacity of the building. The operation is based on installing room temperature on/off control valves on the branch lines of each household to control the on/off of the user's circulating water and achieve room temperature regulation for that household. At the same time, room temperature acquisition controllers are placed in representative rooms of each household to measure indoor temperature and user set temperature, and transmit these two temperature values to the on-off control valve. The on-off control valve determines the on-off ratio of the on-off valve within a control cycle based on the difference between the measured room temperature and the set value, and controls the on-off of the on-off regulating valve according to this on-off ratio to regulate the heat input into the room. At the same time, the on-off control valve of each household is recorded and counted, and the heat of the entire building is shared based on the cumulative on-off time of each household combined with the heating area. Real time dynamic monitoring of various data on the operation of the heating system through the management platform, timely response to various problems that occur in the system, and providing a basis for management personnel to carry out system maintenance. This method is another major breakthrough in the successful application of modern technology to traditional industries, and is a household heat metering method specified in the national industry standard "Technical Regulations for Heating Metering".

Heating metering control system using on-off time area method

The on-off time area method heating metering control system is independently developed by Linyi Yiphotothermal metering technology Co., Ltd. It adopts internationally advanced M-BUS bus and wireless data transmission technology, combined with the promotion of national new heating technology and the current situation of energy-saving renovation of existing buildings, to design and manufacture a heating household metering system solution. Based on the principles of fairness, justice, and green environmental protection, the heat and heat costs of residents are allocated according to their housing area, heating time, and total heat consumption of the building.

The system consists of the following parts:

(1) Wireless room temperature acquisition controller (installed in individual representative rooms)

(2) Wireless on-off controller (installed in individual stairwells)

(3) Concentrator (installed between stairs or buildings)

(4) BuildingHeat meter(Building Installation)

(5) Heating monitoring and management software

The main technical features include:

(1) Easy and simple engineering wiring: wireless connection between room temperature acquisition controller and on-off controller; The communication between the on-off controller and the concentrator adopts M-BUS bus connection. The building concentrator and heating monitoring management system adopt GPRS network communication method. Suitable for both new building installation and old building renovation;

(2) Heat allocation: Allocate the heat consumption of each heating user, and display the heating consumption, usage time, and overdue notice on the LCD screen of the user end (room temperature collection controller), making it easy for the heating user to understand the heating consumption status and avoid charging disputes;

(3) Remote management: It has functions such as prepayment, remote collection without the need for household meter reading, remote control of on/off valves, intelligent analysis of heating equipment and fault alarm, and automatically stores historical data to improve the management efficiency of the heating department. It also promptly detects and handles faults or human damage to the heat metering system, ensuring reliable operation of the heat metering system and accurate heat metering data;

(4) Real time monitoring of user room temperature: The data center simultaneously collects the cumulative average temperature and real-time temperature of heating users indoors, making it easier for heating companies to understand the actual heating status of heating users;

(5) The software adopts a bookkeeping management structure design, which facilitates data access, settlement, management, and monitoring. It has functions such as heat consumption allocation, heat cost calculation, energy consumption statistics, and data analysis;

(6) Product reliability: The on-off controller has a lifespan of over 100000 times, a pressure resistance of 1.6MPa, a temperature resistance of 95 ℃, a waterproof structure design, a long service life, no water quality requirements, and is suitable for both radiator systems and underfloor heating systems;

(7) Real time fault monitoring: The heating monitoring management software can monitor equipment faults in real time and quickly locate the location and cause of the faults;

(8) The wireless room temperature controller on the user side displays the usage of heat sharing levels on site, with transparent costs and functions such as temperature adjustment and setting of heat usage time periods (seven day mode), organically combining comfortable heating with management, metering, and energy saving;
