随着国民经济的高速发展和小城镇人民生活水平的不断提高,人们对室内环境质量有了更高的要求,即空气的清新卫生、温度舒适宜人、节能经济等。目前,我国普遍采用的热水供暖末端方式有普通散热器供暖,低温热水地板辐射供暖,空调采暖等几种形式。其中,低温热水地板辐射供暖是将采暖热水管道埋设在房间内部地面内的供暖系统。该系统以整个地面作为散热面,地板在通过对流换热加热周围空气的同时,还与四周的围护结构和人体进行辐射换热,从而达到供暖效果,其辐射换热量约占总换热量的50％。低温热水地板辐射供暖系统即能高效地使用各种低品位能源,又具有舒适、节能和有利于装饰等优点,正在住宅和公共建筑中得到越来越广泛的应用。但每一种供暖方式都不是十全十美的,都有优缺点。只有清楚了解它的利与弊,才能更好地应用它。
With the rapid development of the national economy and the continuous improvement of people’s living standards in small towns and cities, people have higher requirements on indoor environmental quality, that is, fresh and clean air, comfortable and comfortable temperatures, and energy-saving economy. At present, the commonly used methods of hot water heating in our country are ordinary radiator heating, low temperature hot water floor radiant heating and air conditioning heating. Among them, the low-temperature hot water floor radiant heating is the heating hot water pipe buried in the room inside the ground heating system. The system uses the entire ground as the cooling surface, while the floor heats the surrounding air by convection heat transfer, and also radiates heat with the surrounding enveloping structure and the human body so as to achieve the heating effect. The radiation heat transfer accounts for about the total heat exchange 50% of the amount. Low-temperature hot water floor radiant heating system that can efficiently use a variety of low-grade energy, but also has the advantages of comfort, energy saving and conducive to decoration, is being more and more widely used in residential and public buildings. However, each heating method is not perfect, both have advantages and disadvantages. Only by clearly understanding its pros and cons can we better apply it.
