新西兰▓ ▓ ▓ 准备安装家庭通风系统，请求大家分享
在新西兰
家里是40年的老房子了， 每个冬天如此“冻人”， 而且枕头被褥总是潮的！！！ 实在不想这个冬天再忍受潮湿和寒冷了！！所以决定安装个通风（换风）系统， 查了下资料，得到一些公司的资料，想问下安装过的家庭
1， 那家公司值得推荐 （性价比和服务？？）
2， positive pressure（利用屋内空气做循环）和 Balance flow recovery system （估计是利用空调机器调节湿度和温度） 哪个更适合家庭
3，家里是4房的，费用可能是多少
4，耗电怎么样，大概一个月几钱啊？？
感谢大家，随贴附上 从EECA下载的表格， 大家帮忙说说吧

Report to EECA: January 2009
32Home Ventilation Systems Assessment
Appendix 2. Summary of main types of ventilation systems
System
Passive
Passive stack
Exhaust (spot)
Negative pressure (whole house exhaust)
Positive pressure with roof cavity heat transfer
Balanced pressure with heat recovery
Applications
Trickle ventilation to parts or all of a house
Part or whole house, sometimes in conjunction with mechanical systems
Spot ventilation of wet areas (e.g. kitchen, bathrooms)
Whole house background ventilation
Whole house ventilation for new and existing houses
Whole house ventilation for new and existing houses
Advantages
Simple to use, understand Low maintenance No running costs or electrical connection
No running costs or electrical connection Low maintenance Quiet
Easy and inexpensive
Effective in dealing with localised steam/ humidity issues - reduces the likelihood of contaminants being spread to other spaces
Relatively easy and cheap to install
Allows good control of intake air filtration Can precondition outside air
Potential heating energy benefits from using roof cavity air
Optional inlet sources, valves and controllers can enhance system performance
Allows good control of intake air filtration Ventilation largely independent of weather Provides efficient pre-heating of incoming air Energy efficiency benefits from heat exchanger
Disadvantages
Irregular and intermittent ventilation – dependent on weather condition, wind pressure etc
Likely to need mechanical back-up/supplementation to achieve consistent ventilation
Irregular and intermittent ventilation, especially in hot weather as dependent on temperature gradients
Difficult to install unless specifically designed
Likely to need mechanical back-up/supplementation to achieve consistent ventilation
Fans generally noisy
Generally not suitable for bedrooms and living areas – areas that require consistent ventilation
Doesn’t allow incoming air to be filtered or otherwise conditioned - unfiltered air drawn through gaps and openings in building elements may be polluted and hazardous.
May entrain pollutants from combustion, attached garage, ground (moisture, radon) etc
Risk of moisture damage to structure in hot-humid climates
Houses need to be well sealed especially the ceiling in order to prevent backflow of stale, moist air
Not recommended for very cold climates because of potential moisture entrainment and damage to structure
Lower cost systems generally don’t include desirable options
Roof cavity heating benefit highly dependent on specifics of houses, system and climate
Concerns about potential air contamination from roof space
Generally more expensive to install than positive pressure systems
Needs careful design and installation to avoid uneven pressurization and spatial pressure variations
Houses need to be well sealed otherwise likelihood of excessive ventilation and energy waste
Comment
Can be useful but they don’t provide consistent ventilation in all weather conditions
EST regard as good practice but not best or advanced practice for new houses unless assisted in some form
EST regard as good practice but not best or advanced practice for whole house and new houses
Common overseas but not common in NZ
Most common ventilation systems sold in NZ but there is a lack of agreed guidance on design and performance parameters
EST regard as good practice but not best or advanced practice for new houses
EST regard as best practice for new houses
Note that this table draws heavily from overseas sources, particularly the Energy Saving Trust (EST - Ref 12), so is not particularly focused on the specifics of New Zealand.

感觉没多少用，找房子的时候找过装hrv的房子，因为房东不开窗，里面霉味特别大，房东还在那里吹因为他家有hrv房子有多温暖多干燥呢。

装空调也不错，抽湿效果更快

保溫绵最重要

建议按保温棉+通风换气系统才可以看到很明显的效果，只用其中一个效果不大

哦,还有更多吗

我家也是老房子,买房子之前以前的房主装的，冬天一点都不潮，而且早上起来窗户上一点水都没有，以前住apt的时候冬天起来玻璃上都有水珠的，不知道其他人如何，我家还满有用的

hrv和dvs其实都用处不大。。。。
还是装空调系统好的多。。。。。

请问楼主现在做好了吗？能否分享经验？谢谢！

Roman, 我家刚装了一个，感觉价钱不错，朋友介绍的。
发个email给我，我回复你他的联系方式。。

有通風口的房沒水珠。有一間房沒有口，有水珠。
對比明顯。不太費電。長遠是不錯的。
空調，抽濕機都是有效果的。但個人覺得長遠更費電，有局限性，還有點小燥音。
