Key areas and summary of energy-saving innovation in urban buildings
1. Optimize architectural design
Including the building and the external environment for heat exchange, natural ventilation, natural lighting optimization design
2. New building envelope material
The main products are: external wall insulation and insulation, roof insulation and thermal insulation, excellent thermal physical properties of the external windows and glass curtain wall, intelligent external sunshade devices and phase change material based thermal storage envelope and based on the polymer Hygroscopic interior materials for hygroscopic materials
3. Ventilation and exhaust heat recovery unit
The main products are: honeycomb aluminum film, heat pipe and other sensible heat recovery and heat recovery at the same time can be solved at the same time the summer heat recovery of paper and polymer film through the whole heat recovery device
4. Heat pump technology
By heat pump technology from low-temperature heat source to take heat, enhance its temperature, to provide heat for the building. The main technologies involved are: heat pump domestic hot water unit technology, air source heat pump technology, groundwater source heat pump technology, sewage water source heat pump technology, underground buried pipe soil heat pump technology
5. Reduce the energy consumption of transmission and distribution systems
Research and development of water-based transmission and distribution systems, including: research and development of efficient low-lift, constant flow characteristics rather than the constant pressure characteristics of the pump; inverter , motor and controller with the pump body integrated frequency control pump; Water drag reducers and phase change materials
6. Large-scale public buildings, energy-saving control regulation
Effectively adjust the energy consumption of large-scale public buildings, especially heating and air conditioning systems to automatically adjust
7. Building thermal power triple system
Use of power plant first by the gas-fired power generation, and then use the waste heat after power generation to heat the building or as a cooling air-conditioning power, access to higher fuel efficiency
8. Coal-fired gas combined heating and end of peak
Adopting large-scale central heating network, using coal as fuel, raising basic load of heating, stable operation during the whole heating season, small peak-shaving boiler adopting natural gas as fuel at the end to replenish insufficient heat according to load demand
9. Energy-saving lamps and energy-saving lamps
Including: efficient light source technology, high efficiency lighting technology, lighting control technology
