Compared with prior art, the present invention builds on the basis of every basic function needs satisfying the Utilities Electric Co. building, reaches energy-saving and cost-reducing effect, and the present invention is equally applicable to similar building building, has the meaning of popularization.
The specific embodiment
The invention will be further described for following comparative examples.
Embodiment 1
The investigation of some underlying parameters of electric power building, data analysis:
It is reported, bigger and unbroken productivity load are arranged in the particularly secondary building in the building, mainly be controlling equipment and communications equipment room equipment, account for about 10% of total energy consumption, the employee of Utilities Electric Co. has more working overtime and situation such as meeting festivals or holidays in addition, all to producing higher energy consumption index certain influence is arranged.
Annual accumulative total air conditioning energy consumption data are higher, and main cause is that the transparent curtain wall of the peripheral structure in building partly accounts for larger proportion, causes the result that air conditioner load is big, heating load is little.
Annual accumulative total heating air conditioning energy consumption data is higher, illustrates that the power consumption in building fails to reach existing energy saving building standard, and certainly, the building construction did not also have the design standard of energy saving building aspect at that time, so surely belong among the reason.
Be subjected to seasonal effect and that the part of energy consumption fluctuation takes place is less, summer and winter all have only 14%, existence bigger annual constant energy consumption in building be described.Whether further investigation reveals that has 20% fan coil still to locate running status in two-day weekend and workaday quitting time approximately, should further investigate it and can close.
Building winter heating thermal source is mainly from seven air source heat pumps, be aided with electric heating steam boiler, air source heat pump heating is more energy-conservation mode, if but by once calculating, the comprehensive efficiency of its seven air source heat pumps is 58%, still is lower than general natural gas heating equipment.
DeST is the abbreviation of building thermal environments design simulation kit (Designer ' s Simulation Toolkit), it is that Tsing-Hua University's Building Technology Science is the crystallization of architectural environment and equipment research institute more than ten years scientific achievement, is to be used for the software platform that the building thermal environments design simulation is analyzed.DeST is on stream all the time being applied to analogue technique to build with the analysis of architectural environment control system better, studying and be designed to aim, so it is the strong instrument that numerous building designers and correlative study personnel are used to simulate, analyze and solve the practical problem of building and air-conditioning system.Shanghai Power Company building building is carried out the conclusion of analog computation and analysis and evaluation on the DeST platform, in conjunction with Utilities Electric Co.'s building construction characteristic and function of use characteristics, the Utilities Electric Co. building can be taked the measure of saving energy and reduce the cost in the following areas:
Fan coil is energy-conservation in the air-conditioning system.By analysis as can be known, Utilities Electric Co.'s building fan coil energy consumption after work is higher, and the energy-conservation concrete measure of fan coil has:
(1) the investigation fan coil is still located the reason moved in two-day weekend and workaday quitting time, reinforcement is to the education of the employee of office awareness of saving energy, put up " last leaver please close illumination and air-conditioning power supply " etc. similarly identifies in all big offices and conference room doorway, stick colored ribbon at air outlet, remind indoor employee's air-conditioning draught fan whether in running order, the air-conditioning draught fan of tour personnel in the unmanned office of quitting time discovery in time of also being convenient to tenement still located duty, can in time take corresponding measure;
(2) can consider that at technical elements the power supply that increases an illumination and fan coil always cuts off switch, switch panel uses colored eye-catching color, makes things convenient for the employee can " key pass " when next;
(3) can consider to increase a time switching device, the time of configuration switch power supply, guaranteeing under the situation that the employee " forgets the pass ", still can powered-down, can realize the total building energy saving rate in this Utilities Electric Co. building about 4%.
Room lighting energy-conservation.By analysis as can be known, the energy consumption of this Utilities Electric Co. building room lighting part also is higher, and the conservation measures of this building room lighting mainly contains:
(1) uses the high-efficiency and energy-saving type light source, reduce the lighting power density value;
(2) adjust the illumination control loop, when illumination is strong, close the illuminating lamp of a side near the window, make full use of the characteristics of this building large-area glass printing opacity curtain wall;
(3) increase the station lighting source, reduce the large area lighting light source, be implemented in generally under the prerequisite that guarantees need of work, reduce the purpose of average lighting power density, can realize the total building energy saving rate in this building about 5%.
Transparent curtain wall energy-conservation.By analysis as can be known, one of the architectural feature in this building is the clear glass curtain wall space enclosing structure of vast scale, and this vast scale clear glass curtain wall is slightly beneficial to the minimizing of winter heating load, but the corresponding summer air conditioning load that also increased.The internal sunshade measure that the suggestion design arrangement is rationally economic again, can effectively reduce room conditioning load in summer, in can adopting, concrete main mode pastes the low light transmission reflective membrane, the position that is primarily aimed at is the following position of waist of the indoor side of clear glass curtain wall, energy-conservation purpose be can reach like this, view perspective and indoor natural light illumination do not influenced again.The energy-saving effect of internal sunshade transformation finally realizes by reducing the summer air-conditioning energy consumption, can realize the total building energy saving rate in this building about 4% to the internal sunshade transformation of transparent curtain wall.In addition, make full use of existing shading blind summer, also can reduce certain air conditioning energy consumption effectively.
More than three energy-conservation suggestions add up to and can realize the total building energy saving rate about 13% in this building.
