中央空调水系统清洗的重要性!

来源: 日期:2019-05-16 发布人:admin
  中央空调在平常工作进程中,水系统会呈现水垢、藻类、生物粘泥、铁锈等金属腐蚀产品,这些物质不时堆积在冷凝器、换热器、风机盘管内侧和管路内,构成管路通质变小,影响换热效果,更由于污垢导热系数低,当污垢堆积物掩盖在换热器的换热面时,就会大大降落制冷换热效率,致使冷凝器压力增加,制冷效果降落,动力耗费大幅上升。污垢还加速腐蚀,使中央空调机组寿数缩短。因些,中央空调必需顶起停止清洗。
  In the normal working process of central air conditioning, the water system will present metal corrosion products such as scale, algae, biological clay, rust and so on. These substances are accumulated in the inside of condenser, heat exchanger, fan coil unit and pipeline from time to time. The quality of pipeline becomes smaller and the heat transfer effect is affected. Moreover, because of the low thermal conductivity of fouling, when fouling deposit is concealed on the heat exchange surface of heat exchanger, it will become larger. Large drop of refrigeration heat transfer efficiency results in the increase of condenser pressure, the decrease of refrigeration effect and the increase of power consumption. The fouling also accelerates corrosion, which shortens the life of central air conditioning units. For this reason, the central air conditioner must be jacked up to stop cleaning.
  中央空调在工作进程中常呈现结垢、生锈、制冷效果降落,耗电量上升,严重时以至发作高压跳机现象,经过完善的清洗后,中央空调制冷效果明显改善,俭省了紧缩机工作时间,机组俭省用电10-30%,并延伸运用寿数。如一房间,在中央空调清洗前,降至设定温度需非常钟;而中央空调清洗后,降至设定温度仅需七分钟,则紧缩机可少工作三分钟,然后俭省用电30%。往常的现状是:很多的中央空调制冷效果欠好,致使延伸紧缩时间,糜费电力,经过中央空调清洗可使空调恢复正常制冷效果,缩短紧缩时间,俭省用电10-30%。
  Central air-conditioning often presents scaling, rusting, cooling effect dropping, power consumption rising, and even high-pressure jumping phenomenon in the process of work. After perfect cleaning, the cooling effect of central air-conditioning is obviously improved, the working time of compressor is saved, power consumption of unit is saved by 10-30%, and service life is extended. For a room, it takes ten minutes to set the temperature before cleaning the central air-conditioner, and only seven minutes to set the temperature after cleaning the central air-conditioner, then the compressor can work three minutes less and save 30% of electricity. The current situation in China is as follows: many central air conditioners have poor refrigeration effect, which leads to the extension of contraction time and the wastage of electricity. Cleaning of central air conditioners can restore normal refrigeration effect, shorten contraction time and save electricity by 10-30%.
  一毫米的水垢将使中央空调机组制冷量降落20%-40%,一同使冷凝器压力增加,致使电机负荷增加,多耗费电能20-30%。若机组容量为100万大卡,设备能效比为3.2kw/1万大卡,平均负荷80%,一年工作10个月共5000小时,则一年需多耗电:100×80%×3.2×5000×(10-30)%=12.8-38.4万度,以每度电0.8元计,每年糜费的电费有10.24-30.72万元(溴化锂机组糜费的是燃料费)。此糜费是无量而无形的。
  One millimeter of scale will reduce the refrigeration capacity of central air conditioning units by 20% - 40%, together with the increase of condenser pressure, resulting in an increase in motor load, which consumes 20 - 30% more energy. If the unit capacity is 1 million cards, the energy efficiency ratio of equipment is 3.2 kw/10,000 cards, with an average load of 80%, and the unit works for 5,000 hours for 10 months a year, it will consume more power in one year: 100 *80%*3.2 *5,000 * (10-30)%=12.8-384,000 degrees, and the annual electricity cost is 10.24-307,200 yuan (lithium bromide unit is the fuel cost). The waste is immeasurable and invisible.
  一、中央空调水系统清洗重要性
  I. The Importance of Cleaning Central Air Conditioning Water System
  中央空调的水系统分为冷却水和冷冻水两个系统:
  The water system of central air conditioning is divided into cooling water system and chilled water system.
  冷却水系统主要靠冷却塔散热,水在冷却塔中因滴溅和活动后会与空气充沛的接触,然后把空气中很多的尘土、微生物、可溶性盐及腐蚀性气体带入冷却塔中,使水杂质浓度不时增加,这给中央空调系统的工作带来很多危害。
  Cooling water system mainly relies on cooling tower for heat dissipation. Water in cooling tower will contact with air abundantly after splashing and moving. Then, a lot of dust, microorganisms, soluble salts and corrosive gases in the air are brought into the cooling tower, which makes the concentration of water impurities increase from time to time. This brings a lot of harm to the work of central air-conditioning system.
  危害表现:尘土、盐类、细菌、溶解氧等→发作水垢、菌藻、锈渣→堆积在主机铜管、过滤器→循环变慢→散热效果差→制冷效果差→糜费动力→缩短设备寿数。
  Hazard manifestations: dust, salt, bacteria, dissolved oxygen, etc. scaling, bacteria and algae, rust residue accumulation in the main copper pipe, filter slow circulation poor cooling effect poor cooling effect waste power shorten the life of the equipment.
  冷冻系统是一个密封系统,铢积寸累,水中溶解氧很简单构成盘管梗塞,机组及管路附件腐蚀,然后构成制冷量衰减和设备的过早损坏,直接影响到中央空调系统正常工作。
  Refrigeration system is a sealed system, baht accumulates inches, dissolved oxygen in water is very simple to constitute coil infarction, unit and pipeline accessories corrosion, and then constitute cooling capacity attenuation and premature damage of equipment, directly affecting the normal operation of the central air conditioning system.
  危害表现:水腐蚀管道内壁→发作锈渣→梗塞主机盘管及风机盘管→致使盘管炸裂或没有制冷效果→糜费动力→缩短设备运用寿数。

  二、中央空调水系统清洗原理
  2. Cleaning Principle of Central Air Conditioning Water System
  1、经过向循环系统参与GJ-2B灭菌粘泥剥离剂,铲除循环水中的各种细菌和藻类。
  1. Participate in GJ-2B sterilizing slime stripping agent through the recirculating system to eradicate all kinds of bacteria and algae in the recirculating water.
  2、参与剥离剂,将管道内的生物粘泥剥离坠落,经过循环将生物粘泥清洗出来。
  2. Participate in peeling agent, peel off and fall the biological slime in the pipeline, and wash it out through circulation.
  3、参与化学清洗剂(GJ-中央空调工作清洗剂),将管道系统内的浮锈、垢、油污清洗下来,松懈排出,复原成清洗的金属外表。
  3. Participate in chemical cleaning agent (GJ-central air-conditioning working cleaning agent) to clean the floating rust, dirt and oil in the pipeline system, release them loosely, and restore the metal appearance of cleaning.
  4、投入预膜药剂,在金属外表构成细密的聚合高分子维护膜,以起防蚀效果。
  4. Input the pre-film agent to form a fine polymer maintenance film on the metal surface to prevent corrosion.
  5、参与缓蚀剂,避免金属生锈,一同参与阻垢剂,经过概括效果,避免钙镁离子结晶堆积。并守时抽验,监控水质。
  5. Participate in corrosion inhibitors, avoid metal rusting, participate in scale inhibitors together, through the summary effect, avoid calcium and magnesium ion crystallization accumulation. Punctual spot checks are also carried out to monitor the water quality.
  普通空调在运用年今后,其能效比衰减百分之八(8%)支配;运用三年后的空调产品,其能效比降落可高达百分之二十五(25%)。依据在全国300多家星级酒店查询得知:往常宾馆傍边运用的各种中央空调,在工作了一段时间今后,会很明显的发作衰减,长时间工作的中央空调,其能效比衰减可抵达百分之二十五(25%)以上,构成了运用单位的动力开支糜费。
  In the first year of operation, the energy efficiency ratio of general air-conditioning will decrease by 8% (8%) and the energy efficiency ratio of air-conditioning products will decrease by 25% (25%) after three years. According to the inquiries of more than 300 star-rated hotels in China, it is known that all kinds of central air-conditioners used in the vicinity of the usual hotels will have obvious attack and attenuation in the future after a period of work. The energy efficiency ratio of the central air-conditioners working for a long time can reach 25% (25%) or more, which constitutes the wastage of power expenditure of the employing units.
