21 October this year, after the fact since the strongest cold air makes the most of the region in southern China temperatures dropped 5-14 ° c.
Days beginning to fade in the cold, cold, many southern residents envy the North heating of life.
Currently, only some of the southern region of high-end residential area towards commercialization of central heating, a majority of city dwellers is mainly made of air conditioners, heaters, electric blankets, coal and charcoal, etc., all around the lab.
The South region is there need for central heating mode?
Southern people, and heating needs urgent
October 26, to participate in the work in the morning, just 4 months of Yin Xiangyi risked gales chill rush to go to work, this time, he is remembered for reading spent 6 years in Beijing the "warm."
Likewise have just graduated from Beijing went to participate in the work of Chan Huina also said: "the weather really makes me miss the Beijing!"
Although both Hunan, but they seem to have fallen in love with the North heating in winter.
"In the North, heating a opened, no matter how cold outside, return home as if or spring. "Yin Xiangyi said, hometown most can not stand is that no heating in the room," during the Spring Festival back home, I will relapse of Chilblain, evening drilling cool quilt, a long sleep. ”
Think of freezing rain and snow 2008 disaster weather, Hunan a newspaper reporter Ding Yang light still feel apprehensive.
He recalled that at the time to visit over Hengyang interview because Beijing-Zhuhai Expressway, hengzao trapped three or four days on the road, because of the blackout, the air conditioning could not be used to write script in a hotel as if staying in the ice-cold, you can only add one by one.
When it comes to heating in winter, the Hunan lawyer Zhang Jing memories of childhood: in discarded paint bucket with burnt red, charcoal, to go to school, in the classroom lesson edge warming himself.
In yuelu Mountain Lake of commercial civilization under peach Street, reporters saw some shops have been put on the gloves, scarves, water bottle, pancake charging heater and other commodities, and a handful of students where to buy.
Hunan normal university students xieyan said that winter in the inside, the rooms must have heating, to concentrate on his studies.
Changsha Kaifu district Kettle ponds Liao Zi community residents, said that if the Government can provide central heating, it's a good thing to improve people's livelihood, "I am not accustomed to through the fire to keep warm, with heating, it need not feel air conditioning high electricity bills!"
The traditional way, environmental protection energy-consuming not
North Central heating temperature is 18 ° c-16 ° c.
In recent years, the cold air constantly southward, to the dividing line between rain and snow to the South of Yangtze River, often resulting in the southern provinces of low temperature freezing rain and snow, weather resulted in the Yangtze River Valley indoor temperature is generally less than 10 ° c lower than 10 ° c in the North, extreme minimum temperature below 0 degrees centigrade even. To this end, during this year, the Hunan provincial deputies Wu and sticks on the southern region of central heating.
She said that the central heating is not only able to upgrade quality, keep indoor constant appropriate temperature and humidity, in implementation of water at any time to have access to effective to improve the living environment and the rational use of energy and reduce air pollution.
She suggested that, in the southern region of central heating should be incorporated into five national "12" construction planning, by State and province levels according to the focus of the project the full amount of funds invested, and will include heating subsidies and rural residents in the budget.
Currently, the majority of city dwellers in the South of the main use of air conditioners, heaters, electric blankets, coal and charcoal, and other ways to keep warm.
Suning appliance Changsha branch of life player in the electrical goods Purchasing Manager Lai, commenced from 14 July, Changsha 9 suning appliance shop has all of the electrical heating, zhinuan on the shelf and sold more than 100. He also revealed that, from 2008 onwards, suning appliance in Changsha Zhinuan appliances sales growth every year to reach 100%.
The industry believes that in rural areas using coal and charcoal heating, often only precautionary measures, not paying attention to ventilation, prone to carbon monoxide poisoning.
And air conditioning, electric blankets, electric heaters, etc. often makes the city electricity load weight, high energy consumption, energy-saving environmental protection, not without.
Hunan University Dean, Mr. rain architecture that currently along the Yangtze River to the South of the city building warm measures is very vulnerable, especially a lot of hotels are mostly taken air conditioning warm, there is no other appropriate heating measures, energy-intensive way of building a resource-saving and environment-friendly society demands.
South heating, left to right away?
For the southern region of central heating, a sound that southern region winter time is short, central heating, fully laying pipes, operating costs are high, and the southern region of coal resources relative to the North the more nervous.
Wu and sticks, construction Department of Hunan province at that time gave her answer is: it is recommended that very well, is from the perspective of good people, but the central heating is a systems engineering, research must be conducted and scientific programming.
Journalists in the interview process, the drawbacks of traditional heating mode and weather causes Hunan heating market start "warming", but the main form of the distinguished from North Central heating, and home heating.
Recently, a group of heating are poured into Changsha market, through the boiler, floor, etc. for heating has become the pursuit of living people.
But the industry indicated that the prevalence of small, decentralized, non-market mess and service standards and consumer object focus on income levels higher middle class range is also limited to high-end residential area. Some developers through geothermal systems covering buildings heating as house sales of a selling point.
Wei Gu rains said, from the climate characteristics, Hunan is necessary to do the "central heating, but still not specific to do a perfect answer.
"The industry discussions of a hotspot is a" district heating "— that is, the modular air conditioning, a building or a few hundred square meters area heating, this theory upThat input is small, easy to operate, but also have not put into practice. As for central heating, a system of work in practice to take into account many factors.
Chief Engineer of Hunan Institute of cooperatieve believes that the current southern area heating should regard personal family income levels.
The southern area to promote the North through the realization of thermal power plant way down the central heating was unnecessary.
The ins and outs of centralized heating
According to the Ministry of housing and urban-rural to experts, in accordance with the relevant provisions, the heating area is generally leinian mean daily temperature is lower than or equal to the number of days in excess of 5 ° c for 90 days of the region, including North, Northeast, Northwest Territories.
Reportedly, after the founding of new China, Northern workers rely on coal-fired heating for the winter, when there is a fee for the "warm" subsidy.
In the late 1950s, gradually adopting central heating, heating costs depend on the welfare of workers of "hidden" Supplement. Welfare heating system until 2003. That year, the city heating system reform guidance "introduced, stop units turnkey trade by heat system by households (Hot House) payment directly to the heating company, implemented by heat heating. With the residential construction of large-scale, centralized heat supply is rapid development of 2010 will exceed 40 million square meters.
It is learnt that the dividing line between North and South heating is located on the lines the Qinling Mountains —.
This area is South of central heating, because these areas leinian mean daily temperature is lower than or equal to the number of days is 5 ° c for 90 days.
Professional analysis, the main feature is the South heating batch dispersing heating, if taken with electric heating, in General, one heating season a square just power consumption 5 kWh — 10 kWh, need to pay about $ 2 to $ 5.
If the centralized heat supply, according to the southern city of pilot, a square only a month to pay $ 7, the ordinary burden will increase.
Experts said that for now, according to lifestyle, people paying capacity and economic considerations, the South also not suitable for the implementation of centralized heating.
Businesses aiming at South heating "cake"
Frost descent just after the Typhoon "Catfish" and double the weight of the cold air, Zhejiang Hangzhou temperature suddenly fell by 10 degrees.
Maybe in Zhejiang, this is not the winter, but from Harbin Xiaoxia in Hangzhou College has put on cotton maoku, "last year, despise the Hangzhou winter cold hands and feet are made of Chilblain, early start this year must prepare", slightly bitter and xiaoxia said, "I don't know why you people in the South for the winter!"
Indeed, from the South there is no heating in winter, the most common way of heating is air conditioning.
But the high cost of air conditioning and heating, energy consumption, high comfort difference cratering is more obvious, southern ordinary families often only in the coldest days, long winter, Southerner always is "get back".
But today, the people's living standards, the requirements for life is getting higher and higher.
South, the low-carbon green ground heating?
In fact, many businesses have been aimed at the millions of people in this big cake-press survey found that some geothermal heating equipment, boilers and other manufacturers are across the River to Hangzhou, and other southern cities, 497, but more and more people in the South have also begun to re-examine the heating problem.
In the home market operation warm qiutao road of Fujian merchants forest xuguang, South of the city was warm, the market just a blank spot up basic are northerners in the installation.
However in recent years, has not used the warm southern people are to find warm, last year, the business became increasingly popular. This year haven't winter, have more and more companies see the warm the huge opportunity that ran over to grab the market, to warm the shop around for several more.
In addition to the decoration industry saw South heating business opportunities, some of the real estate business also played this cake idea.
Hangzhou Xiasha a building called "constant temperature and humidity" of real estate ads. The principle is simple through the "ground source heat pump system" cold water as the medium for irrigation depths of the underground (for underground 40 meters). Water absorption after underground heat and smoke it. Through the pipeline, reserved heat dispersion to the appropriate room. In this way, we will be able to ensure the indoor perennial 20-26 ° c, humidity maintain 30%-70%.
According to reports, these real estate prices than with area real estate, but a more expensive launch became buyers snap up objects.
It can be seen from the South on the urgency of the heating demand and market potential of the enormous business opportunities.
