【 Weak current College 】 communication building a detailed analysis of the energy-saving measures

This article focuses on the communications, energy reduction in energy consumption, the significance and importance of the economic analysis, and communication building energy-saving technical management measures.

1. Overview

As the network continues to expand the scale of the construction, energy costs in total costs of a gradual increase in the ratio, for the further implementation of the "network of the savings potential, increase efficiency, reduce" network operation costs, energy-saving activities will be carried out is to promote operational efficiency, improve maintenance level of important ways.

2. economic analysis

2.1 to build "smart energy-saving ventilation system", for instance, according to preliminary data, according to the geographical experiments, station, season, etc., maximum power savings of up to $ 800 per month, enabled us to achieve reduction in electricity charges estimates about 7000 Yuan, about half a year payback.

2.2 "change air conditioning set temperature" for example, when the base station, the air conditioning for 2P operating temperature adjustment is 25 degrees than the operating temperature is set to 22 degrees less electricity consumption per hour, the province's estimated 0.4 annual savings of electricity will reach approximately 170 million; at the same time shorten compressor run, and extend the life of the air conditioning.

2.3 by changing power module in use, the rate of increase in the single module load. To improve operating efficiency, reduce electricity costs. To the base station load 70A, 300A system single module load rate of 23%, and productivity of about 87%, when close two 50A module enables single module load rate at 35%, the working efficiency of about 89%, saving electricity per hour about 0.04 degrees, throughout the whole year can save electricity to about 150 million.

3, to carry out energy conservation activities proposed measures

3.1 optimization, adjust power and air conditioning equipment operating parameters and environmental

3.1.1 air conditioning

Adjusting the base station air conditioning buildings run set temperature, it is recommended that you set values: single cold air-conditioning: various branch according to the base station adjust set temperature, minimum temperature should not be lower than 25 ° c; air-conditioning: summer 25 ° c, 15 ° c in winter.

? Take full advantage of the power monitoring of environmental monitoring, science and determine the base station conditioner down date.

? Machine room exclusively used air conditioner set temperature 22 ° c in summer and winter: 18 ° c; If the equipment density, air blocking reasons may cause overheating of the branch under actual conditions of specific settings available.

For the current device installed capacity building is not great, air conditioning, cooling capacity, redundant enough, after accounting for the protection of all parts of the temperature in the engine room, turn off some air conditioning to achieve the aim of increasing energy efficiency.

Office air conditioning: summer estate set temperature 26 ° c, the indoor temperature is higher than the 26 degrees to open air conditioning; winter setting temperature of 15 degrees, the indoor temperature is below 15 degrees in order to open the air conditioner.

? For equipment room, when no person should close room lighting (Board room also can reduce the room illumination).

3.1.2 power device

? The base station is not the power under a specific adjustment module run number, the principles of the protection of the load and battery charging current is up to leave a hot backup module; proximity, the importance of base station is not high, so monitoring base station as far as possible, no hot backup module; extra module in the base station on cold standby.

3.2 strengthening equipment maintenance, reduces loss

3.2.1 in strict accordance with the requirements of the maintenance job plans, regular air conditioning equipment for maintenance, you can increase the duration of the maintenance frequency. Regular outdoor condensing fin, indoor unit filter cleaning, improved heat transfer efficiency; check the motor bearings and other sports sites, when an exception occurs in a timely manner to adjust, oiling, avoid mechanical loss; repair damaged refrigerant tubes as well as restorations of refrigerants, in a timely manner to improve cooling efficiency can reduce energy consumption.

3.2.2 enhance power equipment maintenance, periodic checks and fastening cable connectors to avoid heat loss, timely cleaning power modules, filters, can also reduce wear and tear;

3.2.3 improve power factor, reduce the harmonic components. Council room power on duty to pay attention to power factor compensation Cabinet work for not putting into operation or power factor compensation is too low, timely processing, reduces transformer and cable copper loss.

3.2.4 for central air conditioning of Council housing, office buildings, according to the load is adjusted in host, pumps, etc. run number, avoid large flow small temperature difference of situation, avoid the motor runs at low efficiency section; the economy is good, it can be frequency, automatic control technology to achieve energy-saving transformation.

3.2.5 strengthen meter readings of checks, to verify that the establishment of each station with the station account. For the base station each month's meter reading, with the previous month and similar station power consumption for contrast, then press the load power in general accounting, if there is an exception, you should immediately on verification, school, avoid stealing power failure, leakage, electricity meters, and so irregular causes an increase in electricity charges.

3.2.6 increased engine room maintenance work, for sealing, outlet hole has a gap plugging in a timely manner to ensure the room good heat resistance; the engine room and out do people through the door closed, the window does not do seals or insulated, be processed in a timely manner to avoid external thermal transmission increases the cooling load.

3.3 adopts proven significant economic benefits of new technologies, reducing energy consumption

3.3.1 smart energy-saving ventilation system: from experimental data, install energy-saving ventilation system particularly for device load larger active station there is a significant energy saving effects, while its temperature, humidity and air cleanliness control within the specification requirements. Recommended reference ventilation energy saving system pilot summary report, based on the own resources arrangements and maintenance, energy-saving effect significant base station first install a ventilation sectionEnergy system to reduce energy consumption.

3.3.2 Summary of ventilation and energy-saving test data

3.3.2.1 investment and economic analysis

According to the test data, in accordance with the test base station equipment density, load, geographic location, housing structure, and other factors, the trial period-saving approximately from 2600 to 800 degrees, the base station power consumption by an average of 1 Yuan/degree price, saving electricity costs approximately 2600 to $ 800. According to the pilot data, outdoor air temperature in the range of 10 to 28 ° c, power-saving effect is best when, 9-12 months for energy-saving effect is good season, estimated annual savings of approximately 7000 to tariffs of 2500 $; to purchase a $ 4500 ventilation system, about a year and a payback; at the same time as the air conditioning running time shortened so that the air conditioning failure rate reductions, increased life expectancy, a better investment economics.

3.3.2.2 building ventilation and energy-saving system of basic conditions

1) on the base station of the selected station: due to the different station types, structures, and other factors have combined effect of the energy saving effect of ventilation system, maximization of energy-saving benefits, according to the pilot experience, we recommend the following priority criteria to select priority installation of base stations.

? Unit density: station equipment-frequency, dual-network or total stations, equipment density, high calorific value of the base station.

? Base station location: located in the city or town, the better the quality of the environment, the surrounding non-corrosive pollution emissions.

? Station building structure: housing structure for activity room to install the system and energy-saving effect is better than ordinary brick house.

? Stations air conditioning configuration: stations on a high power air conditioning energy saving effect of base station better than small power and air conditioning.

The average annual temperature? is relatively low (Chengdu) area energy conservation effect relative may be better than other regions in the Alpine region, but the energy saving effect overall may be poor.

? For some DC load is low, the air conditioning power low base station (such as the DC load below 50A, air-conditioning use 1.5P base station) or geographic location affect large temperature difference between the winter and summer, in winter season December to March air conditioning is turned off, its energy-saving effect will further reduce the investment recovery period is expected to reach 2-3 years.

2) ventilation energy saving system features:

?-Saving costs to lower the interior temperature control within the scope of the specification requirements, main setpoint recommendations are as follows: air conditioner temperature set at 25 ° c, the air conditioning temperature is 28 degrees started, fan start temperature of 25 degrees.

Due to the need to bring in outside?, cold air, the air filter needs to have higher requirements, while not increase too much maintenance workload, it is recommended that you select under station-environment can be repeated cleaning air filters, such as flat-type air conditioner filter or ordinary class type filter or use with the automatic cleaning of the filter. At the same time in view of the area humidity larger features for all systems shall be on an outdoor humidity detection capabilities.

? You need to implement the ventilation system on the base station air conditioning control, simple through the air conditioner AC input of control may be because the air conditioning frequent start causing contact burning, it is proposed to adopt contactless controller or directly to the air conditioning control panel to switch control. In order to avoid multiple base station air conditioning control, later power monitoring system base station status no longer on the air conditioning is recommended and switch control.

Through the ventilation system air flow tests on, than on the results, to achieve more rapid cooling and better energy-saving effect, General base station fan recommends greater than 2000 m3/h, high calorific value of the base station is greater than 2 400 m3/hour.

? As base station for battery configurations, while the two groups 24V-500AH in the summer period power circumstances relatively few, because of the blackout caused the indoor temperature is high; in order to avoid the ventilation system used DC battery back-up power supply time problems, it is recommended that the ventilation system using AC power supply with power-down memory function.

3.3.3 other energy-saving technologies:

Currently on the market with various power saving technology, and to conserve electricity can play a role; encourages the conditional branch to ensure network security based on a small-scale pilot, analysis of its investment in economy, as is evident energy saving, significant economic benefits, haveno effect on network devices, for approval to the application in full screen.

3.4 Office of electricity-saving measures

3.4.1 rational adjustment indoor illumination, making full use of natural light; places where conditions are to make full use of sunlight sources, closed or partially closed lighting lights;

3.4.2 hallway, bathroom, etc should be optically controlled lighting, audio and control switch, do people go the lights.

3.4.3 phasing out energy is high, the intensity of the incandescent lamp, low and high efficiency, long life-saving lamps.

3.4.4 office computer should be set to power-saving mode, when a long time to automatically turn off when not in the peripherals, reducing energy consumption.

3.4.5 after work, electric, water heater, office computer, printer and other Office equipment should make people leave after the device off.

3.5 tariff quota management

To further effective conservation of electricity, it is recommended that the introduction of the branch on a tariff quota in the station building. In the prophase station electricity on the basis of, in line with the principle of "seeking truth from facts", according to the current use of energy-saving technology to develop a consumption (according to the characteristics, the station is also available on the annual quota for the calculation of the cycle), as did not increase the load, the station house electricity benchmarking. Through the use of energy-saving technology means related to the lower power consumption, when a calculation of the cycle is complete, regular summary analysis, find energy saving experience, find the feasibility of further energy savingThe analysis of the reasons beyond the quota, the next improvement, the effective promotion of energy-saving work in further depth.

3.6 price cleanup

At present around the city, the remote base station access power mode, the price difference is large; some price charges extremely unreasonable or inconsistent with the relevant provisions, that is their electricity costs higher for an important reason.

3.7 will implement energy saving consciousness construction in the early

Through the adoption of reasonable accommodation transformer, avoid larger loss; base station conditioners full consideration of the installation location, the nearby thermal requirements can not be blocked, try to avoid direct sunlight; station lighting uses high efficiency fluorescent lamps and other energy-saving measures, the project is the implementation of the "energy saving", the energy conservation work done prior to avoid equipment put into operation during the transformation.
