几个关键词和部分英文资料片断 ——

 

 

Earth-to-air heat exchanger

地下土壤-空气热交换器

 

 

Ground-air Heat Exchangers

地下土壤-空气热交换器

 

 

 

 

Earth-to-air heat exchanger

地下土壤-空气热交换器

 

 

This can be done by an earth warming pipe ("ground-coupled heat exchanger"), usually about 30 m to 40 m long and 20 cm in diameter, typically buried about 1.5 m below ground level.

通过地下土壤使管道（中的空气）变暖这是可以做到的（“地源热交换器”），通常长度大约为30米至40米，直径20厘米，通常埋在地平面以下大约1.5米。

 

 

In Germany and Austria this is a common configuration for earth to air heat exchangers.

在德国和奥地利，这是地下土壤与空气之间热交换器的常用配置。

 

 

In high humidity areas where internal condensation could lead to fungal / mould growth in the tube leading to contamination of the air, several measures exist to prevent this.

在高湿度地区内部冷凝可能导致真菌 / 霉菌生长，导致管内空气的污染，有多项措施，可以防止出现这种情况。

 

 

Ensuring the tube drains of water.

确保管道中出现的水的排出。

 

 

Regular cleaning

定期清扫

 

 

Tubes with an imbedded bactericide coating such as silver ions (non-toxic for humans)

使用嵌入一层例如银离子杀菌剂涂层的管道 (对人无毒)

 

 

Air filters F7 / EU7 (>0,4 micrometres) to traps mould (of a size between 2 & 20 micrometres).

空气过滤器 F7 / EU7（大于0.4微米）陷阱模具（2和20微米之间的大小）。

 

 

UV air purification

紫外线空气净化

 

 

Use an earth to "water" heat exchanger.

使用地下土壤与“水”的热交换器。

 

 

The pipes may be either corrugated/slotted to enhance heat transfer and provide condensate drainage or smooth/solid to prevent gas / liquid transfer.

 

 

Air quality

空气质量

 

 

This is highly site dependent.

是高度依赖于建造地点。

 

 

Radon

氡

 

 

One critical problem being located in soils with underlying rock strata which emit radon .

一个关键的问题在土壤下面的岩层所排放的氡

 

 

In these situations the tube needs to be airtight from the surrounding soils, or an Air to Water heat exchanger be used.

在这些情况下需要密封的管周围土壤，或一个空气水热交换器被使用。

 

 

Bacteria and fungi

细菌和真菌

 

 

Formal research indicates that Earth-Air Heat Exchangers (EAHX) reduce building ventilation air pollution.

正式的研究表明，地下土壤空气热交换器（EAHX）减少了建筑的通风空气污染。

 

 

Rabindra (2004) states,

拉宾德拉沙（2004）指出，

 

 

“The Earth-Air Tunnel is found not to support the growth of bacteria and fungi; rather it is found to reduce the quantity of bacteria and fungi thus making the air safer for humans to inhale.

 “地下空气管道被发现不支持细菌和真菌的生长，相反，它被发现，还减少细菌和真菌的数量，从而使人类更安全的空气吸入。

 

 

It is therefore clear that the use of earth-air heat exchangers not only helps save the energy but also helps reduce the air pollution by reducing bacteria and fungi.”

由此可见，地下土壤空气热交换器的使用不仅有利于节约能源，也有助于减少空气污染，减少细菌和真菌。

 

 

Likewise,

同样，

 

 

Flueckiger (1999) in a study of twelve Earth-Air Heat Exchangers varying in design,

Flueckiger（1999）在一项研究中，设计12个不同的地下土壤热交换器，

 

 

pipe material, size and age,

管道材料，大小和年限，

 

 

stated,

说，

 

 

“This study was performed because of concerns of potential microbial growth in the buried pipes of 'ground-coupled' air systems.

进行这项研究是因为担心在地埋管道地下土壤空气热交换系统的潜在微生物生长。

 

 

The results however demonstrate, that no harmful growth occurs and that the airborne concentrations of viable spores and bacteria ,

然而，结果表明，没有发生有害生长活孢子和细菌，空气中的浓度，

 

 

with few exceptions,

除了少数例外，

 

 

even decreases after passage through the pipe-system,

甚至在通过管道以后还降低了，

 

 

and further stated,

并进一步指出，

 

 

“Based on these investigations the operation of ground-coupled earth-to-air heat exchangers is acceptable as long as regular controls are undertaken and if appropriate cleaning facilities are available”.

根据这些调查，地下土壤与空气热交换器是可以接受的，只要定期进行控制，如果提供适当的清洗设施。

 

 

 

 

 

夏天，室外炎热的空气，温度为30度，通过一段较长的地埋管道，进入室内时，温度变为20度。

 

（在冬季，这个过程正好相反。）
