外机一个是重，另一个是室外高空作业，自己犯不着去干这个。
其实可以让工人把外机固定到位，然后就可以让他们走人了，剩下的自己搞。

【 在 FLYBBS 的大作中提到: 】
: 如果不是装空调需要把很重的外机拎出去，我就自己装了。
: 抽真空15分钟的都不多。

比起R22，简而言之就是效率高加更环保
这玩意儿加注耗时是真的，哥伦比亚兄弟花了一个小时才搞定，连工带料大概三千毛币保修三个月，目前两个月了效果可以

What’s the New Refrigerant?
The replacement for R22 is R410A. This new type of refrigerant is what modern HVAC systems are designed to use. If you purchased a system after 2010, chances are it uses R410A.

R410A differs from R22 in a number of ways. R22, a hydrochlorofluorocarbon, is one of the last ozone-depleting substances still commonly used. R410A is not a hydrochlorofluorocarbon. R410A is much better at absorbing and releasing heat. As a result, it’s much more efficient.

Why Make the Change?
Here are a few of the biggest reasons the changeover is such a good idea:

Reduced ozone damage: R22 causes ozone depletion when it leaks. As a result, it’s a danger to the continued health of our planet.
Reduced cost: With the phase-out of R22, it’ll be difficult to find, driving up costs and making repairs extremely costly. If your service technician can’t get hold of R22, they won’t be able to make the necessary repairs, leading to dramatically reduced efficiency.
Improved efficiency: R410A is able to absorb and release heat better than R22, making it more energy efficient. Plus, because it’s more fluid in temperature changing abilities, it does a better job heating or cooling your house quickly.
Improved performance: R22 has a harder time letting go of heat, which means it’s more likely to cause a compressor burnout than the more flexible R410A.

你搞反了，旧的贵，因为不生产了。R22绝对比R410A贵的多

我懒得管这些安装细节
加好了 制冷好 有保修
齐活

【 在 pony7411 (小马哥变成老马了) 的大作中提到: 】
: R410A理论上必须液态加，气态有分层，会把整个制冷剂的成分比搞乱的。而且R410A压力比R22高很多

听我老师说，他家空调十年了三凌还给免费上门检查，不知道是不是包清洗。
