Heat metering scheme -- on-off time area method

Principle of on-off time area method

In the residential building thermal entrance building installation of heat meters, the total heat metering of the ban;

A metering control valve is installed on the user's home pipe to control the on-off of the user's heating water and record its opening time;

A temperature controller is installed in the user's room, the temperature controller measures the room temperature, and the on-off of the metering control valve is controlled according to the set temperature, so as to automatically control the temperature of the user's interior;

The data acquisition system of each user heating opening time, through the remote data transfer to management system platform, system platform combined with the families of the whole building area apportionment of heat, heat metering system monitoring, data transmission, data processing, printing, and ticket charges according to the charge management.

On-off time, area method, system diagram and equipment configuration

Each household configuration: temperature controller, metering control valve or metering controller, electrothermal valve

Building configuration: building heat meter, balance valve, power box, data acquisition box etc.

System configuration: system management server, system management platform software

On-off time area method technique characteristic

Room temperature intelligent control technology, good temperature control performance;

Valve delay switch technology, to avoid simultaneous valve switching, to prevent pipe flow fluctuations;

Reduce the influence of heat transfer effect among households and improve the fairness of charging;

By the valve on and off time charges, strengthening the user's awareness of energy conservation;

The metering equipment is installed outdoors, and needs no door construction. The installation and maintenance are convenient and the construction is quick;

The on-off valve has the advantages of simple structure, low water quality requirement and convenient installation and use.

On-off time, area method, system characteristics

Simple operation: the user adjusts the temperature to be convenient;

Remote control real-time monitoring: remote control function, remote control, to achieve mandatory open and close the valve, to prevent malicious arrears;

Practical protection mechanism: power down memory prevents data loss;

Distributed system: unlimited capacity expansion, with high adaptability, large capacity and so on;

Set permissions, data security: the system administrator can set different levels of operator permissions, different levels of operator can be assigned permissions for different management; metering control system, data acquisition box, can monitor computer for data storage, the system can also use multiple monitoring computer monitoring computer data storage. Can mutually backup, thus greatly improving the safety and reliability of data storage

Personalized reports: system software has a flexible report printing function, the system provides a variety of report forms for users to use, but also according to user needs to customize the form.

Card break, time area method, functional characteristics

It has the functions of on-off time, area measurement, measurement and control mode transmission, etc.

Local credit card remote recharge: with local credit card recharge, remote network recharge function; prepaid management, malicious arrears and lack of fees, automatically cut off heating function;

Early warning, prompt users to pay: to avoid the normal heating due to arrears;

A variety of charging methods: to support the cumulative running time, the cumulative energy consumption, the preset heating time interval and other billing methods;

Multi encryption, to prevent theft of heat: multiple data encryption, effective suppression of malicious decryption, stealing heat;

Unique number, effectively prevent wrong card: the device has a unique user number, will not brush wrong card;

Own intellectual property open interface

Energy-saving management

Warning: automatic alarm for trouble.

Heat metering system - user calorimeter

Principle of household heat meter

In the residential building thermal entrance building installation of heat meters, the total heat metering of the ban;

A user uses a heat meter to measure the user's heat on the user's home pipe;

A temperature control valve is installed inside the user to automatically control the user's room temperature;

The data acquisition system of the users of the hot water on time, through the remote data transfer to management system platform, system platform combined with the families of the whole building area apportionment of heat, heat metering system monitoring, data transmission, data processing, bill printing and charge management.

Household heat meter system diagram and equipment configuration

Each household configuration: household heat meter, temperature control valve or thermostat and electric valve

Building configuration: building heat meter, balance valve, power box, data acquisition box etc.

System configuration: system management server, system management platform software

Characteristics of household heat meter system

The household heat meter directly displays the heat used by the user:

The premise of the method is that each household should be an independent circulatory system (radiator system, floor water heating system);

Ultrasonic calorimeter:

The utility model has the advantages of high flow measurement accuracy, low pressure loss, easy blockage and long service life;

Household heat meter method should consider the problem of congestion or damage:

Household heat meter system diagram and equipment configuration

System overview: on the return pipe installed on the heat meter for heating heat metering and the floor consumption; the electric control valve installed in the return pipe, the temperature control box to dynamically adjust the valve opening, is used to adjust the flow of the heating hot water floor, in order to meet the demand of comfort, energy saving. The data acquisition system passes all kinds of data to the system platform through the GPRS remote transmission system, and realizes the automation of equipment management;

The system features: can realize heat collection; can be carried out in different periods, different temperature control can be divided into unit; building, floor, separate control; with low temperature freezing function, safe and reliable;

Scope of application: it is applicable to public offices such as government, schools, hospitals, factories and other office buildings and office buildings.

Effect of heat balance modification on heat source and heat supply network

Variable frequency speed control of water pump:

Variable flow control method is an important part of energy saving control system, and also an important means of water saving;

Hydraulic balance can be achieved by reforming the effect:

The water flow of each subsystem is in a balance state, and the quality of the heating is greatly improved, and the economic operation is realized, and the system is truly energy-saving;

Heat exchange station control:

Through the outdoor temperature compensation, the heat supply and demand can be adjusted uniformly;

Energy consumption monitoring:

To realize the energy consumption monitoring platform of equipment, electricity consumption, gas quantity and water supply quantity.
