Building Automation System (BAS, Building Automation System) is one of the main components of intelligent buildings. The intelligent building realizes the comprehensive monitoring and management of the equipment and the building environment in the building (group) through the building automation system, creating a comfortable, safe, economical, efficient and convenient working and living environment for the building users, and optimizing the operation of the equipment and Manage and reduce operating expenses. The building automation system involves the building's electricity, lighting, air-conditioning, ventilation, water supply and drainage, disaster prevention, safety protection, garage management and other equipment and systems. It is the sub The design level and engineering construction quality have a direct impact on the realization of intelligent building functions.
The role of building automation system is monitored in real time to avoid accidents. The computer system monitors the mechanical and electrical equipment and the building environment in real time, and monitors hidden dangers that cannot be discovered by manual workers at any time, so as to make up for the lack of manpower and avoid major losses.
Meet comfort requirements, automatically control indoor constant temperature and humidity, ensure proper temperature and humidity, and provide employees and customers with a comfortable environment; automatically deliver fresh air to ensure fresh air and reduce office syndromes; humanized intelligent lighting Control, make work more convenient.
Scientific management and cost reduction. Through BAS's automatic monitoring and effective management of the electromechanical equipment in the building, it is possible to use the least energy consumption to maintain the normal operation of the equipment and save energy. Through the timing management of the equipment, the service life of the equipment is prolonged and the maintenance cost of the equipment is saved. The BAS system greatly facilitates the operation and maintenance of equipment, greatly improves the work efficiency of maintenance personnel, and reduces enterprise labor costs.
The main function of the sensors in the building automation system is to make the entire building safer, more energy-efficient and comfortable. The carbon dioxide sensor, like the temperature and humidity sensor and other sensors, belong to the bottom layer. They transmit their measured values to the data collector through digital or analog signals. Then it is passed to the central processing unit through the data collector. The central processor then controls the actions of each device through the controller. Through the central processing unit, the main function of the carbon dioxide sensor is to adjust the volume of fresh air in the building to keep the indoor air fresh. Save energy consumption of air conditioners and ventilators.
Low-power HVAC dedicated infrared carbon dioxide sensor
ISweek industrial mining network provides British GSS infrared carbon dioxide sensor (NDIR CO2 sensor) COZIR-A can effectively detect indoor carbon dioxide concentration
The carbon dioxide sensor COZIR-A is a high-performance CO2 sensor with ultra-low power consumption (3.5mW). It is an ideal choice for battery-powered products and portable equipment; based on IR LED patented technology and innovative light path design, the carbon dioxide sensor COZIR Become the lowest power consumption NDIR sensor; and optional temperature and humidity output. The carbon dioxide sensor COZIR is the third-generation product of GSS, and the leader in IR LED CO2 sensing technology.Three optional ranges are 0-2000ppm, 0-5000ppm and 0-1%, which makes the carbon dioxide sensor COZIR-A more suitable for application in building automation (HVAC) and agricultural greenhouses
For most residents or users, the convenience facilities provided by the intelligent building make people happy. But for investors: how much can we save? How much is it? How long does the investment take to see the benefits? The calculated result is that the benevolent sees benevolence, and the wise sees wisdom. But for a building automation system, the advantages of using carbon dioxide sensors can be reflected in the following three points summarized by ISweek industrial mining network:
1.Carbon dioxide sensor improves the living environment and makes people feel more comfortable
Even if they don’t know the role of carbon dioxide sensors, people still like to live in a more comfortable place, hoping that a better environment will bring a more comfortable business space. A good indoor air atmosphere can bring greater efficiency. Good ventilation is easier for the emission of harmful gases and eliminates the risk of unhealthy factors such as acute diseases, such as asthma, asbestos, cancer, and so on.
2.CO2 sensor reduces energy consumption
Just like by controlling the temperature and humidity at each point, the actual demand for lighting, by controlling the carbon dioxide content to control the exchange of fresh air, so that the environment maintains the best comfort, while the operating cost is minimized. This also slows down the global environmental energy consumption and the increased global greenhouse effect, and reduces them together. Moreover, according to the 1997 "Kyoto Protocol", the country is now working hard to reduce the greenhouse effect and promote green and energy-saving housing.
3.Lower maintenance costs
In the management of intelligent buildings, by monitoring the entire system components, building managers can design and perform maintenance in a more efficient manner, and the actual maintenance situation is mainly based on the actual needs of the maintenance rather than a predetermined schedule. Before anything goes wrong, the analysis of performance degradation and other possible signs of damage can provide the necessary measures to prevent it. In this way, normal working hours can be used for repairs, replacing the extra damage caused by expensive emergency repairs.
As people's living standards continue to improve, the cost of carbon dioxide sensors is further reduced, and the concept of green energy-saving is deepened, carbon dioxide sensors will be more widely used in buildings and homes for green and environmental protection, and they can reflect their advantages. It will bring people a better, more environmentally friendly and more energy-efficient green life.
