It refers to providing users with an efficient, comfortable and convenient humanized building environment by optimizing the structure, system, service and management of the building according to the needs of users. Intelligent building is the product of modern science and technology. Its technical foundation is mainly composed of modern building technology, modern computer technology, modern communication technology and modern control technology.
According to the data of "Analysis Report on the Development Prospect and Investment Strategic Planning of Intelligent Building Industry in China in 2013/20/7", after the first breakthrough of 20 billion yuan in 2005, the market of intelligent building industry in China also developed at an annual rate of more than 20%, and the market scale reached 866,543.8 billion yuan in 20 12.
Smart home touch screen defines smart building as "building as a platform with information facilities system, information application system, building equipment management system, public safety system, etc.". It integrates structure, system, service, management and its optimization to provide people with a safe, efficient, convenient, energy-saving, environmentally-friendly and healthy building environment. "
The original national standard "Design Standard of Intelligent Building" (GB/T503 14-2000) defined intelligent building as "building as a platform, building automation equipment BA, office automation OA and communication network system CA, integrating structure, system, service and management and their optimized combination to provide people with a safe, efficient, comfortable and convenient building environment".
Monitoring and management of central air conditioning system;
1. Monitor the air conditioning system of the whole building (including fan coil control, bypass control of hot and cold water pumps, water inlet control of cooling tower, etc.). ).
2. By measuring the supply/return water temperature and flow rate of cold water, the cooling load of the air conditioning system is automatically calculated and displayed on the CRT of the building automation system.
3. The group control device of air conditioning water chillers determines the start and stop times of water chillers according to the actual cooling load, so as to achieve the best energy-saving effect. ?
4. Measure and automatically control the pressure difference of the supply/return main pipe of the chilled water system, and maintain the pressure difference required by the system.
5. Interlocking control of chilled water pump/cooling water pump. When a chilled water pump fails, it will automatically put into standby pump.
