购买新风系统要注意什么
发布时间: 2017年11月13日 | 次浏览 | 分享到:

A.风机

A. fan

家用主要有150风量、250风量、350风量,意思是每小时出风150/m3,250/m3,350/m3。

The main household has 150 air volume, 250 air volume, 350 air volume, meaning hourly wind 150/m3250/m3350/m3.


150风量的大概是适合房子70平以内的。250风量能管120平以内的,再大的就得上350风量的。

150 air volume is probably suitable for the house within 70 flat. 250 air volume can be less than 120 flat, and then large on the 350 air volume.


噪音一般是强档的时候要控制在40分贝左右。但不需要24小时开强档,刚回家开1个小时就差不多,换成弱档24小时微循环就行了。

The noise is generally hot when you want to control in about 40 db. But do not need to open 24 hour hot, just go home 1 hours for almost 24 hours, weak file microcirculation on the line.


功率一般都100多瓦,弱档也就几十瓦,等于一个电风扇吧。

Power is generally more than 100 watts, weak file also tens of watts, equal to an electric fan.


B.管道

B. pipeline

现在主要有2种,一是PVC管,99%的在用这种,跟家里用的那种白色的排水管差不多。另一种是PE管,成本高,至少多收4千块,是热熔型,安装起来很麻烦。注意一下,靠近室外的进、出风管道,都要包一层保温管或者保温棉,避免因为温差太大产生冷凝水。

Now there are 2 main types, one is the PVC tube, and the other is 99%, which is similar to the white drain pipe used at home. The other is a PE pipe, high cost, at least 4 thousand pieces, hot melt type, it is inconvenient to install. Note that the inlet and outlet pipes close to the outside should be covered with a heat preservation pipe or a heat preservation cotton, so as to avoid condensation water due to too large temperature difference.


另外建议隔半年看一下风口,取下来,拿水冲一下,你会看到灰常灰常多滴灰。

In addition, it is recommended to look at the tuyere every six months, take it down and take a shower of water, you will see the ash often ash.


C.滤材

C. filter material

现在的滤材一般都是什么样的?就是分为纯物理过滤和静电吸附。纯物理过滤就是用滤芯,静电吸附也叫静电集尘,是用的静电箱,里面放钨丝。

What kind of filter material is it now? They are pure physical filtration and electrostatic adsorption. Pure physical filtration is the use of filter core, electrostatic adsorption is also called electrostatic dust collection, is the use of static box, inside the tungsten wire.


这两种方式各有利弊,物理过滤比较彻底,但是后期需要更换滤芯,大概隔3~6个月,就得换一次,一个滤芯200~300块,淘宝京东都是按套卖,3个一套。

These two methods have advantages and disadvantages, physical filtration is thorough, but the latter need to replace the filter, probably every 3~6 months, will be for a time, a 200~300 filter block, Taobao Jingdong are on the basis of a set of 3 sell.

静电方式,好处是不用换滤芯,能拿下来用水洗。缺点是会释放一部分臭氧,一般人都不太愿意接受,很多厂家宣传控制在国家标准范围之内。还有说微量臭氧让人很爽,我也没有验证过,见仁见智吧。反正臭氧超量是肯定有害的,容易咳嗽、气短、皮肤痒等等。 现在很多人在装新风的时候都是滤材也用,静电集尘也用,混搭起来,效果更好。

Electrostatic way, the advantage is not to change the filter cartridge, can take down with water. The disadvantage is that some of the ozone will be released, people are not willing to accept, many manufacturers propaganda control within the national standard. There are said micro ozone people very cool, I have not tested, Different people, different views.. Anyway, excessive ozone is certainly harmful, easy to cough, shortness of breath, itchy skin and so on. Now many people install fresh air when the filter is also used, electrostatic dust collection is also used, mix together, the effect is better.


D.热交换

D. heat exchange

让室外进来的空气也能保持跟室内一个温度。现在市面上的新风系统,热交换率一般都能达到80%左右(国内大部分酒店新风系统热交换率在50~60%之间,还是差那么一点事儿),外面的空气,经过新风后,进入室内,跟室内原来的温度相差仅在几度的范围。这样,冬天不会因为新风吹进的凉空气,大家着凉感冒。我了解的是,现在不管什么品牌,哪个国家的新风,热交换没有能做到跟室内温度一样的,都会差几度。买的时候,要注意两个英文单词HRV和ERV。HRV指的是简单的热交换,不是全热交换,是显热交换,不管湿度调节。ERV就是全热交换了,能做到有限的湿度调节的功能。

Let the outdoor air also keep a temperature with the room.  Now on the market of fresh air system, the heat exchange rate can reach about 80% (most of the domestic hotel air system heat exchange rate between 50~60%, or a thing), the outside air, through the air after entering the room is only in the range of a few degrees with the original indoor temperature. In this way, the cold air won't be blown in by the fresh air in winter, so people catch cold. What I understand is that, no matter what brand, which country's new atmosphere, the heat exchange can not do as the indoor temperature is the same, will be several degrees. When you buy, pay attention to two English words HRV and ERV. HRV refers to simple heat exchange, not total heat exchange, sensible heat exchange, regardless of humidity regulation. ERV is the total heat exchange, can achieve limited humidity regulation function.
