In order to implement the national laws, regulations, principles and policies on energy conservation, improve the indoor environment of public buildings in Tianjin, improve energy utilization efficiency, reduce building energy consumption, and promote the application of new and renewable energy, the design standard for energy conservation of public buildings in Tianjin was revised according to the climate characteristics and specific conditions of Tianjin. Among them, what is the monitoring, control and weighing of public buildings in Tianjin public building energy-saving design standard? The following is the introduction of monitoring and weighing of public buildings in Tianjin brought by Construction Network for your reference.

Central heating, ventilation and air conditioning systems should be monitored and controlled. Direct digital control system should be adopted when full air conditioning system is adopted in public buildings over 000m2. Its contents can include parameter detection, parameter and equipment status display, automatic adjustment and control, automatic conversion of working conditions, energy metering and centralized monitoring and management. The specific content should be determined by technical and economic comparison according to the building function, relevant standards and system types.

The energy consumption measurement of heat source, heat exchange room and refrigeration room shall include the following contents:

1, production fuel consumption;

2. Power consumption and cooling capacity of refrigerator;

3. Heating of central heating system;

4. Power consumption of water pump;

5. Water quantity.

When using regional cold and heat sources, cold and heat metering devices should be set at the entrance of cold and heat sources in public buildings. Refrigeration and heat metering devices should be installed in public buildings belonging to different users.

Boiler room and heat exchanger room shall be equipped with heating control devices.

The heating control design of boiler room and heat exchange station shall meet the following requirements:

1, should be able to interlock control of pumps, valves and other equipment;

2, water supply temperature should be able to adjust according to the outdoor temperature:

3, water supply flow should be able to adjust according to the terminal demand;

4, should be able to control the number and speed of the pump according to the terminal demand;

5, should be able to adjust the number of boilers put into operation and fuel input according to the heating demand.

Heating and air conditioning system should be equipped with room temperature control device; Radiators and radiant heating systems shall be equipped with automatic temperature control valves.

The control function of cold and heat source room shall meet the following requirements:

1, should be able to start and stop cold water/heat pump units, pumps, valves, cooling towers and other equipment in sequence and chain control;

2. The number of water chillers should be controlled, and the optimal control mode of refrigeration capacity should be adopted;

3, should be able to control the number of pumps, the appropriate flow optimization control mode;

4. The secondary pump should be able to automatically control the speed change, control the rotating speed according to the water pressure difference between the supply and return, and optimally adjust the water pressure difference between the supply and return;

5, should be able to control the number of cooling tower fans, should be based on outdoor meteorological parameters for speed control;

6, should be able to control the automatic discharge of cooling tower;

7. The water supply temperature should be optimized and adjusted according to outdoor meteorological parameters and terminal requirements;

8, should be able to rotate the use of equipment according to the cumulative running time;

9. For the cold and heat source room with large installed capacity and more equipment, the unit group control mode should be adopted.
