<br> With the rise of China's telecommunications industry, the growing communication network, due to the continuous operation of communication networks, as the room temperature and humidity control of equipment, machine room exclusively used air conditioner in the room equipment power consumption accounted for more .than 50% of the share, is a large energy-consuming. This is the advocate for the background of the room air-conditioning energy saving, the following I will see if you can start from what the purpose of achieving energy saving. <br .> <br> First, the introduction of efficient room air conditioner efficiency is to energy <br> <br> The evolution from the engine room air conditioning, you can know that the engine room air conditioning efficiency has been improved. If the room air .-conditioning compressor seal from half to full sealed piston piston, then to the hermetic scroll-type, energy efficiency ratio increased 25%; therefore we now full close scroll compressor than the early 1980s of air-conditioning equipment to energy-saving 25%; .in addition, the air-conditioned indoor air supply system, fan motor direct energy than the fan belt, and vortex direct connect fan than the first two more energy, such as Eddy fan than belt drive to energy-saving 20% or more. < .br> 1. in order to save energy, the preferred high-efficiency compressor and blower. <br> 2. analysis of the network of air conditioning equipment, energy-consuming older equipment recommendations. <br> <br> Second, the room .temperature and humidity settings for energy-saving control <br> <br> In meeting room technology to determine a reasonable value of temperature, humidity and ventilation rate, can reduce telecom costs, while extending the life of air conditioning equipment, is an important manifestation .of energy saving. Field testing by part of the room and found the room air-conditioning setting temperature increase of 1 ° c, could energy-saving 5% -12%. <br> 1. consider telecom room air conditioner General is always in .a State of refrigeration, so set the temperature value higher, the more energy-efficient; <br> 2. the priority of the temperature, the relaxation of humidity control standards, the according to the seasons, changes in humidity is set to a value .; such as the indoor relative humidity values in the summer may be appropriate to improve, reduce air conditioning dry time; winter room relative humidity values to minimize and reduce air humidification. On some level lower room, you can consider close air humidification and heating function .. <br> 3. all equipment required for the room temperature to know he is a real friend, temperature control is not good reduces communication equipment life, it is best to use telecommunications equipment, selection of high-temperature resistance equipment. <br> .4. not only is the most province, which belongs to the typical defensive energy, will not increase any cost, and energy-saving effect is clear. <br> <br> III. reduce all unnecessary loss <br> <br> Earlier .some room due to the design of an earlier, did not consider the room building energy efficiency, heat loss comparison of envelope, plus some building computer lab and office space when mixed, built to pursue building facade, the proportion of relatively large window wall, .and extensive use of glass curtain wall, these factors will increase the cooling load, causing the engine room air conditioning system. <br> 1. communication building energy-saving design of the building to the engine room. Such as Windows and walls with thermal .insulation properties of materials. <br> 2, in need of fresh air for cooling on the exterior of the season, the fewer the new amount of wind energy; therefore you want to make sure that the room's air leakage reduction Occlusive, and so fresh .air into the engine room. <br> <br> 4. replace the refrigerant will be energy-saving and environmental protection through to the end <br> <br> At present the room air-conditioning use R22 refrigerant is freon, pursuant to .the Montreal agreement will stop use by 2030. In recent years, the market replacements to Asia-azeotropic refrigerant, such as 407C, 418A, 410A (needs rework system), and environmental protection at the same time a certain energy saving effect. Replace new .type refrigerant, on the one hand reached on ozone layer protection requirements, on the other hand, in the reasonable adjustment air conditioning operation condition after new type refrigerant may be appropriate to reduce the air conditioning compressor running-current. <br> 1. a .certain energy-saving effect, and manufacturers information. As a refrigerant, manufacturers data show: energy-saving effect in the 9% -15%; scene done energy conservation effect of 5% -8%, testers, test methods for energy saving effect .of differences lead to significant differences. <br> 2, the actual procedure more cumbersome, refrigerant recovery, preferably by a professional staff to operate, the replacement costs are relatively high. <br> <br> 5. air energy control <br> .<br> We know, fan, pump class load, shaft power and speed is proportional to the cube, and when the blower, pump speed is reduced, the consumption of power is also greatly reduced. Therefore it is proposed to adopt fan adjustable, .such as Italy a brand air conditioning can change motor wiring mode to adjust the fan speed and pressure. <br> 1, according to the engine room and air-conditioning of sensible heat than to choose a reasonable amount of wind. <br> 2 .. energy-saving effect is not evident. <br> <br> VI. room air-conditioning condensing heat recovery <br> <br> Air conditioning in the refrigeration is excreted through the air cooled condenser, and a large amount of heat exhaust .temperature and condensing temperature between huge superheat consumes a substantial part of the condenser coil area, if the prior the heat removed, will be relatively more condensation area without increasing costs. You can increase the heat until the condenser collector to produce domestic hot water, through .a modification of the engine room air conditioning, the crew running the emission of large quantities of waste heat recovery and recycling, transformation is 30 ~ 65 ° c for domestic hot water. <br> 1, on the one hand, reducing the emission of .air conditioner heat, summer can be very good to reduce condensation pressure, improve the efficiency of refrigeration and air conditioning to achieve energy-saving purposes; on the other hand, we get a free hot water, if you can supply an outside line persons bath .; comprehensive results than using the condenser simple use water spray effect. <br> 2, need to be transformed to air-conditioning, equipped with water condenser will increase costs; winter cases difficult to control. <br> <br> 7. adjust .the air conditioning system operating best <br> <br> It is a good device, also without maintenance; the engine room air conditioning only run in the best conditions to play air conditioning for maximum cooling capacity to achieve the purpose of the air conditioning energy .saving. This is the maintenance of the highest of the means is the most effective and most important energy-saving, it is one of the ways we were fighting in the power status: an employee's ultimate goal. <br> 1, maintain good air .conditioning, canVery good effective; maintenance of air conditioning energy consumption only. According to the information, periodic maintenance of air conditioning air-conditioning than does not maintain an average of 25 percent of energy saving in. <br> <br> 8. Add .friction for distinguished not discount <br> <br> This is a super Lube, can better improve the compressor running instances of the lubrication conditions, reduce the friction of the cylinder and the piston, especially the old compressor, lubrication improvement can reduce the compressor .running current to achieve energy-saving purposes. Some additives presented can also improve the efficiency of air-conditioning heat (inhibit pipe wall oil film formation). <br> 1, adding convenience and general air conditioning maintenance personnel trained to master the methods of .operation. New air conditioning system and energy-saving effect is not obvious, but you can extend the service life of the compressor; life in the middle of the old air conditioner has a certain energy saving effect. <br> 2. Add friction for .more convenient, but the price is very expensive additives. <br> <br> 9. close the alternate air conditioning not only most province <br> <br> In-room air conditioning energy to meet the requirements of part of the air conditioning .compressor will no longer work, and the air conditioning fan still continue to work, turn on the blower in continuous conveying air flow, the consumption of energy, so you can meet the room volume load and airflow circulation, close alternate air conditioning, energy saving .fan work. Number of room air-conditioning manufacturers have provided online hot backup and rotation function, you can use this feature off, standby tank air conditioning air-conditioning can be artificially closed. <br> 1, the cost is low, as a .fan of long-running, close the alternate fan has a certain energy saving effect. <br> 2. only available in the computer room air conditioning load smaller, rich has been preparing for machine room. <br> <br> 10, room .air-conditioning compressor adopting inverter technology <br> <br> Traditional machine room exclusively used air conditioner, relying on the compressor constantly "open," to adjust the room temperature; this method is the machine room exclusively used air conditioner compressor installation of frequency .converters, frequency converters to change the frequency of power supply, adjustable compressor compressor speed. Depending on how fast the compressor speed reaches the purpose of controlling the room temperature to avoid the frequent and stopping the compressor. <br> 1. the use of the .frequency inverter to avoid the frequent and stopping the compressor, the compressor to prolong life and prevent computer room temperature fluctuations. <br> 2. This approach, coupled with poor frequency converter, operation; inverter itself to consumption of electric energy, produces harmonics, .telecom room air-conditioning widely used N + 1 configuration, the result in energy-saving effect is not evident. <br> <br> 11. fresh energy-saving system makes full use of nature <br> <br> Fresh energy- .saving technologies of the basic approach is to: ensure the engine room environment, through the sensor real-time comparison engine temperature and humidity and temperature and humidity of the outside the room; when the outdoor temperature and humidity reached can make use of standards, the .introduction of new fans start to indoor outdoor fresh air, reducing air conditioning load even deactivate application outside for fresh air conditioning, cooling capacity, reach of energy saving, energy saving effect. <br> 1. application of new energy-efficient technologies can greatly .reduce the energy consumption, is by far the most efficient air conditioning system and energy-saving measures. Such as Hangzhou region, you can use time high 210 days, North use time longer; in this way, energy-saving effect is clear, according .to the information portion of the House energy as high as 70 per cent. <br> 2, for the introduction of fresh air, the wall openings, etc., on the construction and fire have a certain influence. <br> <br>.
