     冬去春来,你还记得温暖你冬天的取暖方式吗?我国是煤炭消费大国,每年冬天北方居民采暖就要消耗大量煤炭。但煤炭在燃烧过程中会形成大量烟尘、一氧化碳、二氧化硫等物质,严重污染环境。

     听说天津市准备在2020年至2023年延续执行居民冬季清洁取暖的有关政策,也就是大家熟悉的“煤改电”、“煤改气”,在你的生活中是否还使用到了其他高效绿色采暖系统?

As winter goes to spring, do you remember the way to keep warm in winter? China is a big coal consumer, and every winter the northern residents will consume a lot of coal for heating. But in the process of coal combustion will form a lot of smoke, carbon monoxide, sulfur dioxide and other substances, serious environmental pollution.

I heard that Tianjin is going to continue to implement the policy of clean winter heating for residents from 2020 to 2023, which is also known as "coal to electricity" and "coal to gas". Are there any other efficient green heating systems in your life?


绿色的采暖方式有什么?

What does the green heating way have?


1

什么是“煤改气”和“煤改电”?

What is "coal to gas" and "coal to electricity"?


      “煤改气”是指用天然气来取代煤炭,利用天然气加热锅炉提供热水。

      “煤改电”则是用电采暖设备来取代煤炭锅炉。

"Coal to gas" means replacing coal with natural gas to heat boilers to provide hot water.

"Coal to electricity" is electric heating equipment to replace coal boilers.

“煤改气”VS“煤改电”,哪方优势更大?

Which side has the advantage of replacing coal with gas or electricity?


     从普及程度的角度比较

     我国目前天然气主要在城市地区普及,很多农村地区没有燃气管道,而管网的铺设难度大成本高。相比之下,“煤改电”的普及难度就小得多。我国的电网体系已经非常成熟,家家户户都通了电。

Compare from the point of view of popularity

At present, natural gas is mainly popularized in urban areas in China, and many rural areas do not have gas pipelines, and the laying of pipeline network is difficult and costly. By contrast, the "coal to electricity" is much easier to popularize. China's power grid system has been very mature, every household has access to electricity.

     从使用成本的角度比较

     天然气的使用成本较高,大约是过去煤炭采暖的3-4倍,的确有些负担不起。用电采暖的价格明显要低很多,现在已经有了技术成熟的电采暖设备,耗电量折合费用相比于天然气还是要低很多。

Compare from the point of view of cost of use

The high cost of using natural gas, about three to four times that of coal heating in the past, is indeed unaffordable. The price of electric heating is obviously much lower. Now there are mature electric heating equipment, and the cost of electricity consumption is much lower than that of natural gas.


     从安全性的角度比较

     天然气属于易燃易爆气体,目前农村天然气全都是明管管道架设,如果发生泄漏很容易引起爆炸,存在一定的安全隐患。但是我国目前的电网体系比较成熟,供电安全建设措施也比较完善。

From a security perspective

Natural gas belongs to flammable and explosive gas. At present, all natural gas in rural areas are set up in open pipes. If leakage occurs, it is easy to cause explosion, and there are certain safety risks. However, China's current grid system is relatively mature, and the power supply safety construction measures are relatively perfect.

绿色采暖方式

Green heating mode


     方式一:地板辐射式采暖

     “低温辐射地板采暖”是一种利用建筑物内部地面进行采暖的系统。它以低温热水为热媒,均匀地向室内辐射热量,把地板加热到表面温度18℃-32℃。

     这种采暖方式具有热感舒适、热量均衡稳定、节能、免维修、方便管理等特点,成功解决了高空间、大跨度、低窗建筑物的热源问题。

Mode one: floor radiant type heating

"Low temperature radiant floor heating" is a system that uses the ground inside a building for heating. It is heat medium with low temperature hot water, even ground radiates heat to indoor, heat the floor to surface temperature 18℃-32℃.

This heating method has the characteristics of thermal comfort, stable heat balance, energy saving, maintenance free, convenient management and so on. It successfully solves the problem of heat source in buildings with high space, large span and low window.

     方式二:电热膜采暖

     电热膜是一种通电后能发热的半透明聚酯薄膜,以电力为能源,以低温辐射电热膜为发热体,大多数为天花板式,也有少部分铺设在墙壁中甚至地板下。

     电热膜采暖具有恒温可调、经济舒适、绿色环保、使用寿命长、免维护等优点。

Method two: electric heating film heating

Electric heating film is a kind of translucent polyester film that can be heated after electrification. It takes electric power as energy and low temperature radiation electric heating film as heating body. Most of them are ceiling type, and there are also a small part laid in walls and even under the floor.

Electric heating film heating has the advantages of constant temperature adjustable, economic and comfortable, green and environmental protection, long service life, maintenance free and so on.

     方式三:分户壁挂式燃气采暖

     “分户壁挂式燃气采暖”通常是在厨房或阳台上安装壁挂炉,由壁挂炉燃烧天然气达到供暖目的。

     这种方式比传统暖气先进、节能、安全,可安装在墙体上、房间角落里,还可同时提供生活热水。但也存在安全、污染等隐患。

Way three: household wall-mounted gas heating

"Household wall-mounted gas heating" is usually installed on the kitchen or balcony of the wall-hung furnace, by the wall-hung furnace burning natural gas heating purpose.

This way is more advanced than traditional heating, energy saving and safety, can be installed on the wall, the corner of the room, but also provide domestic hot water. But there are also safety, pollution and other risks.

     方式四:家用中央空调系统

     中央空调档次高、节省空间、外形美观、制冷迅速且均匀、舒适度高。但初投资比分体机高,每套机组价值约数万元,每平方米铺装成本高达500元左右,运行费用高(大多为电费),安装复杂,与装修同步。

Way four: household central air conditioning system

The central air conditioning has the advantages of high grade, space saving, beautiful appearance, rapid and uniform refrigeration and high comfort. But the initial investment is higher than the split machine, the value of each unit is about tens of thousands of yuan, the cost of pavement per square meter is as high as 500 yuan or so, the operation cost is high (mostly electricity), the installation is complex, and the decoration is synchronous.

     方式五:水源热泵空调系统

     “水源热泵空调系统”是以地下水为热源,以风机盘管为末端进行强制散热的一种空调采暖系统。

     这种采暖方式涉及诸如水资源、环保等多方面的复杂因素,实施的难度较大,在缺水地区,禁止使用此类设备。

Method 5: water source heat pump air conditioning system

"Water source heat pump air conditioning system" is a kind of air conditioning heating system with groundwater as the heat source and fan coil as the end for forced heat dissipation.

This heating method involves complex factors such as water resources, environmental protection and other aspects, and is difficult to implement. In areas with water shortage, it is prohibited to use such equipment.
