Central heating, energy saving control system for public works

Abstract

An energy-saving control system of centralized heat supply on public building comprises internal net circulation unit set for making hot water in external net be circulated in internal net, temperature transducer for collecting temperature data, electronic temperature controller connected to temperature transducer and used for controlling motor driven regulation valve, and electrically operated regulation valve for controlling flow rate of returning water.

Description

technical field [0001] The invention relates to an energy-saving control system, in particular to an energy-saving control system for centralized heating of public buildings. Background technique: [0002] At present, the total area of ​​existing buildings in my country's urban and rural areas is about 40 billion square meters, and building energy consumption has accounted for nearly 30% of the country's total energy consumption. With the development of the economy, it is estimated that by 2020, my country will add about 30 billion square meters of construction area, and building energy consumption will have a long-term impact on my country's energy consumption. As we all know, the energy consumption per unit building area of ​​large public buildings in my country is about 5 to 10 times that of ordinary residential buildings. Therefore, reducing the energy consumption of public buildings has a crucial impact on the energy saving of the entire building. However, the characte...

Problems solved by technology

However, the characteristics of public buildings and the law of energy use make this effort possible. Regulating and wasting energy

[0003] At present, there are many researches on the energy saving of central heating, but most of them are limited to the boiler combustion in the boiler room and the frequency conversion energy saving technology of water pumps and fans. Due to the low degree of automation of the system, the energy saving efforts made by end users are difficult to be reflected in the heat supply source. Therefore, the energy-saving research or transformation at the end of the system is very limited. At most, it is only to install a water supply frequency conversion pump at the heat exchange station, or to modify the hydraulic balance of the secondary network.
