The energy-saving design of public buildings has the characteristics of simple implementation means, low cost, measurable energy-saving benefits, short payback period, high return and no influence on normal use.
Energy-saving design means of public buildings;
Low-cost transformation technology of central air conditioning-the percentage of air conditioning energy consumption in total energy consumption of public buildings can reach 40% ~ 60%. The application of central air conditioning automatic control technology, or the application of fuzzy frequency conversion control technology and fresh air ventilation technology in the main room can effectively save energy in the air conditioning system, and the cost is low.
Energy-saving of building water supply and drainage system-water-saving technology of installing water-saving appliances (such as water-saving toilet, infrared sensor faucet, water-saving shower, or water-saving valve) and air conditioning cooling water, using sewage from cooling tower to flush toilet and carry out green irrigation.
Energy-saving lighting technology-the use and application of energy-saving lighting lamps and lanterns Automatic lighting control system, such as automatically switching on and off the lights at regular time or through induction, automatically adjusting the brightness according to the illumination, changing the preset scene lighting mode, etc. , can effectively save electricity and energy.
Electrical energy saving-installing equipment to improve power quality can effectively improve the power quality of public buildings, and the energy saving efficiency can reach 8% ~ 15%. In the escalator part of the elevator with high energy consumption, the kinetic energy of the elevator is fed back to save energy, and its frequency conversion governor decelerates the elevator through the motor, or converts the mechanical energy brought by the mass difference between the car and the counterweight into electric energy and stores it in the large capacitor of the DC link of the frequency converter, and the electric energy stored in the large capacitor is fed back to the power grid with little consumption through the active energy feedback device to achieve the purpose of saving electricity; Escalator energy-saving control, that is, adding passenger sensors at the entrance of the escalator, usually has an energy-saving efficiency of 20% ~ 60%.
