- Long-term domestic central air conditioning cleaning industry hysteresis phenomenon worth pondering

    "Wash ah, all the air, filter or something, we have regular cleaning staff cleaning." "Ventilation ducts? Do not know, you ask someone there."

    I recently walked into a random office in Tianjin, a leading property sector, trying to inquire into the situation where the central air conditioning cleaning, a staff member surnamed Zhang replied with such vigilance.

    Although as early as 2003, the State General Administration of Quality Supervision, Inspection and Quarantine, the former Ministry of Construction, Ministry of Health and other departments issued a series one after another on the central air-conditioning ventilation system cleaning and health management-related standards, and to make clear that, however, when to Five years later, still in the domestic cleaning staggering forward. The central air conditioning diligently to provide services for people, but do not mind their own dirty silk appearance, which is also placed in front of the local health department chronic problem — they want to take a bath thoroughly , the difficulty is still small.

    Cliches: Who are willing to "pot of gold"

    "One square meter was thirty-four ten, you count how much money this floor. How to get this money?" I repeated confirmation in the next, although Zhang did not face my questions, but his difficulties will illustrate the problem.

    Statistics show that millions of units in our central air conditioning is being used, more than 90% has not been cleaning systems science, which to varying degrees, there are various bacteria and dust pollution. Some of them are veteran central air conditioning has run continuously for 20 years, but never really "washed a bath." "Everyone knows that health important, let them under the original capital child wash the air, is not easy." Zhang is not the initial binding, "the crisis is now downtown is not correct it? It s surrender of the building has. Rental rates a problem, you who have Xianxin on this matter? "

    Zhang may be right. According to the market some time ago given the price of 35 yuan per square meter basis, to complete a ten thousand square meters office space in central air conditioning cleaning, at least several hundred thousand dollars. Whether the property owner or the company, the money no doubt have been regarded as "heavily" is bound to go through some food for thought. Moreover, now very few companies and property owners in the contract the central air conditioning cleaning the attribution of responsibility, "heavily" so often the source of nothing.

    This is a common, property companies and property owners no obligation to bear the high cost of cleaning, but a long time to work hard to promote this important cause. Vice president of Shanghai Institute of Refrigeration gave away Long Weiding: "In many developed countries, if the central air duct is not cleared, the property will be prosecuted, but the country is, there is no such constraint, for such hidden engineering, business units of consciousness alone is not enough. "

    Hesitates: Who will protect the quality of cleaning

    People "too lazy" to take a bath central air conditioning, the fear not only from money problems, but also cleaning business level. "A lot of cleaning companies do not go through formal training, especially small and medium cities, the situation more." Spent a considerable price, but would not achieve satisfactory results, it is not unfounded. An industry source has publicly questioned: "I know a few cities with a population of millions, not even after a professional cleaning company, cleaning systems training, irregulars how to take up the task?"

    I understand that many domestic cities, central air conditioning variation in levels of cleaning teams have been beyond the general state of the imagination. This expert s attitude is, "the central air conditioning cleaning need to have some technical content as a guarantee," cleaning the management level, experience, and should have a high degree of specialization required, the wrong cleaning methods not only fail to advance the development of effect, but also easily create new sources of pollution, and even ventilation ducts and other facilities would be difficult to envision the damage caused.

    Not just general city, even in Beijing, Shanghai, these mechanisms is relatively sound mega-cities, the situation is not optimistic. It is understood that, at present, Beijing has more than 200 central air conditioning professional cleaning company, adopted the Beijing Centre for Disease Control and Prevention certification, but there are still many non-certified cleaning team in the fish in troubled waters, and the regular army struggled, more worthy of this phenomenon food for thought.

 Take the lead: the first to carry the Beijing-Shanghai "clean banner"

    Just days ago, Yangzhou media, the city health department of health of the local central air conditioning was carried out sampling, sampling, including the amount of dust, respirable particulate matter, total bacteria, total fungi, pathogenic microorganisms and a dozen projects . The results showed that all projects are eligible to use the number of units to zero. This used to have "wealthy" reputation of the city like this, people have filled with anxiety.

    But people are pleased that, Shanghai and Beijing, and several other large cities, or has set an example.

    Last April, the first domestic cleaning central air-conditioning industry association – Shanghai Air Duct Cleaning Association was officially established, marking the Shanghai air duct cleaning services first entered the industry self-management phase. Prior to this, all the cities of Shanghai and China, central air conditioning cleaning rate of less than 10%. I understand that this big market has now gradually reveal the infinite potential. Not only local businesses, Jiangsu, Anhui, Zhejiang and even professional cleaning company around after another, to gain an advantage.

    To correspond with that Beijing also set an example followed. Four months later, Beijing issued a "public places, central air-conditioning ventilation system health management practices", and since the beginning of this year, many companies have central air conditioning cleaning business ever hot up, some of the cleaning company s business volume and even the former can be achieved a few times.

    Beijing health authorities, who declined to be named, told authorities long ago, the city s current central air cleaning rate has exceeded 50%, and a further rise. Next, Beijing related departments will take action to further intensify law enforcement inspections, and through the media, so that more use of central air conditioning unit into the "healthy family."

    Although the media last year, vowed that Beijing will be completed in the middle of this year all central air conditioning cleaning are still gaps, but the authority of the author s position is still confident: "Compared to other cities, Beijing has come to the forefront. No city This can be like Beijing resolutely . "

    However, it was dished out another opinion. Beijing Ocean Environmental Protection Technology Co., Ltd. Market Giant Wong Kan told the author, although Beijing has done a considerable amount of cleaning central air conditioning, but this contains a large number of "Olympics-related or foreign" project, the authoritative statement of the gold content to be confirmed. He admitted, compared to the current Beijing ten thousand office buildings and business personal use of central air conditioning units, complete cleaning of the true proportion is only about 10%, this figure is difficult to make people proud. Wong Kan said that although the current specification of certain rights given to the health sector, but only for their current place of business in the health sectors in issuing licenses to be reviewed and monitored supervision; for non-business premises cleaning, monitoring and control measures is still small.

    "This is a blind spot, including us, including other central air conditioning cleaning companies are waiting for the formal introduction of relevant laws and regulations." Wong Kan said, "now means only a temporary solution."

    Do not lose the anti-earned: need to practice the theory test

    Cleaning as well as "do not lose against making" a unique effect? It is also quite controversial in the industry.

    Some media reported that a group of foreign-funded enterprises of a capacity of 500,000 kcal of central air conditioning units, after the effective cleaning, the annual energy saving of about 12 million degrees, the annual electricity savings of about 10 million (calculated by industrial use) . In contrast, regular cleaning central air conditioning, the cost of cleaning than the first time save a lot of links and the overall cost, time or even just a few thousand dollars.

    Similar calls for, these messages have been gradually formed a unified caliber: Central air conditioning cleaning is definitely a "Hua Xiaoqian Province lot of money," the good deal.

    "It s not down," Wong Kan once again gives a different answer. Considerable experience as a practice of the industry, he told the author, although in theory run the central air-conditioning energy conservation and clean power can bring some influence, but he collected from the customer feedback, this argument is still to be verified.

    "But be sure to clean the air after the air quality improvement benefit. People should understand that a healthy body important than a lot of money." Wong Kan also believes that "cleaned central air conditioning can also be effective reduce the possibility of failure to protect the safe operation of equipment, in a sense, this is the way to save money. "

    This view also received a small number of recognized experts and cleaning companies. Seen in this light, central air conditioning cleaning "does not lose the anti-earned," the cry is flicker or Reality? Theory and practice may also take longer to run.
