辐射供暖

辐射供暖

Radiant heating systems supply heat directly to the floor or to panels in the wall or ceiling of a house. 该系统在很大程度上依赖于辐射传热,即通过红外辐射将热从热表面直接传递到房间中的人和物体. 辐射供暖是当你能从房间的另一端感受到一个热的炉顶元素的温暖时所感受到的效果. 当辐射供暖位于地板时, it is often called radiant floor heating or simply floor heating.

辐射供暖有许多优点. 它比踢脚板加热更有效,通常比强制空气加热更有效,因为它消除了管道损失. 有过敏症的人通常更喜欢辐射热,因为它不像强制空气系统那样分散过敏原. 液体循环系统耗电少, a benefit for homes off the power grid or in areas with high electricity prices. Hydronic systems can use a wide variety of energy sources to heat the liquid, 包括标准燃气或燃油锅炉, 木质的锅炉, 太阳能热水器, 或者是这些来源的组合.

尽管它的名字, 地板辐射采暖在很大程度上依赖于对流, the natural circulation of heat within a room as air warmed by the floor rises. 地板辐射供暖系统与墙壁和天花板上使用的辐射板有很大的不同. For this reason, the following sections discuss radiant floor heat and radiant panels separately.

地板辐射热量

There are three types of radiant floor heat -- radiant air floors (air is the heat-carrying medium), 电辐射地板, 热水(液体循环)辐射地板. 您可以通过安装进一步对这些类型进行分类. 那些利用混凝土板地板或木质底层的轻质混凝土的大热质量的装置被称为“湿式装置”,而那些安装者将辐射地板管道“三明治”在两层胶合板之间或将管道连接在成品地板或底层地板下的装置称为“干式安装”."

地板辐射的类型

热空气辐射地板

空气不能保存大量的热量, so radiant air floors are not cost-effective in residential applications, 而且很少安装. Although they can be combined with solar air heating systems, those systems suffer from the obvious drawback of only producing heat in the daytime, 当加热负荷一般较低时. 用传统的炉子在晚上把空气抽到地板上加热的效率比白天使用太阳能加热的好处要低得多. Although some early solar air heating systems used rocks as a heat-storage medium, 不建议使用此方法.

电辐射地板

Electric radiant floors typically consist of electric cables built into the floor. 该系统的特点是,导电塑料垫安装在地板覆盖物(如瓷砖)下面的底层地板上.

因为电力成本相对较高, 电辐射地板通常只有在包含大量热质量(如厚混凝土地板)和电力公司提供使用时间率的情况下才具有成本效益. 使用时间率允许你在非高峰时段(大约9便士)“收取”混凝土地板的热量.m. 6一个.m.). 如果地板的热质量足够大, 储存在里面的热量可以让房子在没有任何电力输入的情况下保持8到10个小时的舒适, particularly when daytime temperatures are significantly warmer than nighttime temperatures. 与白天用电高峰时供暖相比,这节省了相当多的能源美元.

如果将供暖系统扩展到新空间是不切实际的,那么电辐射地板也可以作为家庭的补充. 然而, 房主应该考虑其他选择, 如微型分离式热泵, which operate more efficiently and have the added advantage of providing cooling.

液体循环加热的辐射地板

循环(液体)系统是最流行和最经济的辐射供暖系统为供暖为主的气候. 循环辐射地板系统通过铺设在地板下的管道从锅炉中泵出热水. 在一些系统中, 通过使用分区阀或泵和温控器控制热水通过每个油管回路的流量,调节房间温度. The cost of installing a hydronic radiant floor varies by location and depends on the size of the home, 安装类型, 地板覆盖, 地点偏远, 还有劳动力成本.

地板安装的类型

无论您使用电缆或油管, the methods of installing electric and hydronic radiant systems in floors are similar.

所谓的“湿式”安装是将电缆或管道嵌入坚固的地板中,这是现代辐射地板系统最古老的形式. 管道或电缆可以埋入厚混凝土底板(通常用于没有地下室的“板式”牧场住宅)或薄混凝土层中, 石膏, 或安装在底层地板上的其他材料. If concrete is used and the new floor is not on solid earth, additional floor support may be necessary because of the added weight. You should consult a professional engineer to determine the floor's carrying capacity.

Thick concrete slabs are ideal for storing heat from solar energy systems, 它们的热量输出波动. The downside of thick slabs is their slow thermal response time, which makes strategies such as night or daytime setbacks difficult if not impossible. Most experts recommend maintaining a constant temperature in homes with these heating systems.

由于最近地板技术的创新, 所谓的“干”地板, in which the cables or tubing run in an air space beneath the floor, 越来越受欢迎, mainly because a dry floor is faster and less expensive to build. 但因为干燥的地板需要加热空气空间, the radiant heating system needs to operate at a higher temperature.

Some dry installations involve suspending the tubing or cables under the subfloor between the joists. This method usually requires drilling through the floor joists to install the tubing. Reflective insulation must also be installed under the tubes to direct the heat upward. Tubing or cables may also be installed from above the floor, between two layers of subfloor. 在这些情况下, 液体管道通常安装在铝扩散器,将水的热量在地板上传播,以便更均匀地加热地板. The tubing and heat diffusers are secured between furring strips (sleepers), which carry the weight of the new subfloor and finished floor surface.

至少有一家公司改进了这一想法,制造了一种胶合板底层材料,其中内置了管槽和铝热扩散板. 制造商声称,该产品使辐射地板系统(用于新建筑)安装成本大大降低,对室温变化的反应更快. Such products also allow for the use of half as much tubing or cabling, 因为与传统的干地板或湿地板相比,地板的传热有了很大的改善.

地板覆盖物

Ceramic tile is the most common and effective floor covering for radiant floor heating, because it conducts heat well and adds thermal storage. Common floor coverings like vinyl and linoleum sheet goods, 地毯, 也可以用木材, but any covering that insulates the floor from the room will decrease the efficiency of the system.

如果你想要地毯, use a thin carpet with dense padding and install as little 地毯 as possible. 如果一些房间, 但并不是所有, 会铺地板吗, then those rooms should have a separate tubing loop to make the system heat these spaces more efficiently. 这是因为在有盖地板下流动的水需要更热,以补偿地板覆盖. 木地板应采用复合木地板而不是实木,以减少木材因受热干燥而收缩和开裂的可能性.

辐射板

安装在墙壁和天花板上的辐射板通常是由铝制成的,可以通过电或管道加热热水, although the latter creates concerns about leakage in wall- or ceiling-mounted systems. Most commercially available radiant panels for homes are electrically heated.

就像任何一种电热一样, 辐射板操作起来可能很昂贵, 但它们可以在某些房间提供补充供暖,或者在传统供暖系统无法扩展时为家庭供暖.

在任何加热技术中,辐射板具有最快的响应时间——因为面板可以为每个房间单独控制——当房间很少有人使用时,与其他系统相比,快速响应的特性可以节省成本和能源. 当进入房间时, the occupant can increase the temperature setting and be comfortable within minutes. 和任何供暖系统一样, set the thermostat to a minimum temperature that will prevent pipes from freezing.

辐射加热板在视线范围内工作——如果你离它很近,你会感到最舒服. 一些人发现安装在天花板上的系统不舒服,因为电池板给他们头部和肩部的顶部供暖比身体其他部位更有效.
