Intelligent Building energy conservation and economic benefits assessment
Intelligent Building energy-saving measures
1 Improving indoor temperature and humidity control accuracy
Indoor temperature and humidity changes and energy conservation are closely related. According to the American National Standards Bureau statistics show that, if the settings in the summer temperature will be lowered 1 ℃, will increase 9 percent of the energy consumption, in the winter if the temperature will be setting up a ℃, will be an increase of 12% energy consumption. Therefore indoor temperature and humidity control in setting accuracy is within the scope of energy-saving air conditioning and effective measures. Europe and the United States and other countries on the indoor temperature and humidity control accuracy: ± 1.5 ℃ temperature, humidity of 60 ± 5% of the change in scope.
In the absence of the traditional construction by building automation system, often causing summer cooling at room temperature (less than the standard settings) or overheating winter temperature (higher than the standard settings) phenomenon. This is not only on human health and comfort terms are inappropriate, but also a waste of energy. Building Automation System used the intelligent building, it can not only set automatic adjustment in accordance with the indoor temperature and humidity aloof, but also according to the outdoor temperature and humidity and seasonal changes, changes in room temperature settings, making them more to meet people's needs, and fully play air-conditioning function. Air-conditioning systems higher precision temperature control, the better not only comfort, and energy-saving effects of the more obvious.
Fresh Air Control 2
According to hygiene requirements within each building must be guaranteed a certain volume of outdoor air. Fresh Air made but too many new wind energy consumption will increase. Hotels in Shanghai as an example, in the design condition (26 ℃ summer outdoor temperature, relative humidity 60 percent, 22 ℃ winter temperature, relative humidity 55%), to deal with one kg of cold outdoor ventilation rate to 6.5 kWh, 12.7 kWh heat Therefore, in an indoor meet health requirements under the premise of reducing outdoor air ventilation rate, a significant energy saving effect.
According to indoor ventilation rate should be allowed to determine the concentration of CO2, CO2 concentrations of the general permit from 0.1% (1000 ppm). Fresh Air fixed to the precise way it is not enough, because with the seasons and time change and air pollution, outdoor air concentrations of CO2 is changing, and indoor staff of the changes in natural fresh air needs have also changed, the most reasonable approach is based on indoor air return or the CO2 concentration, automatic adjustment of ventilation rate to ensure that the indoor air fresh, better control function building automation control system to meet such requirements.
In addition, the energy storage management software can automatically print or equipment operating data and operating curve for the perfect follow-up system to provide reliable information. Various Meter can also be run directly reflect the display data to enhance the energy-saving awareness management
