有没有换了热泵，想换热泵的？进来讨论讨论吧

Heatpump 通常都是变频的，压缩机及風扇都是自动调節速度，比全统冷气省电

请问美的和carrier配件通用吗？

开利合资厂之一。开利有多家合资，在本土和墨西哥都有，但它的产品是开利的而非美的。你可以说美的为开利代工，但不能说美的产品等同于开利产品，美的用的压缩机是国产品牌，开利用的是开利自己的压缩机。不过国产压缩机也不见得差。

换热泵合算不合算，可以自己算算。

Will a Heat Pump Save Money?

搞个新空调应该合算

那是地源热泵，贼贵

我说的是air source。实际使用的体验，上面大家讨论所担心的问题都不存在，但是肯定需要备用热源

WHAT CAN ZUBA MEAN TO YOU?​

Now you can experience the year-round comfort, savings, quality and reliability you deserve. The secret behind Zuba’s superior heating capabilities is our efficient and patented Cold Climate Hyper-Heat (H2iTM) technology. Designed for the Canadian market, Zuba operates at 100% heating capacity at -15°C and continues to deliver exceptional heating performance when the outdoor temperature drops as low as -30°C* and beyond. The unique defrost mechanism provides an extended period of continuous heating between defrost cycles and minimizes the defrost time required.

别信这个，现在骗子贼多。室外温度-5度时效率比直接电加热高点儿。能加热吗？当然能，你在屋里烧个电炉开个烤箱也能加热。但热泵的取热原理完全不是这样的。

这让我想起了上个世纪九十年代那个什么顾雏军，成立了格林威尔公司，自称发明了一种热工循环，效率神奇

Better check the COP of the heatpump at -5C, as long as it's greater than 2.5, it's approximately equal to use natural gas based on gas/electricity prices in April this year.

我已经用了一个冬天了啊

 

[冰中取火]

我已经用了一个冬天了啊

你知道具体冬天取暖是怎么工作的？压缩机方式？电热？燃气？给我们具体详细点的资料。
如果他们混淆一起，那我们几百年都用现在的取暖也没问题啊，这不能说明他们原初鼓吹的“热泵”节能环保。

冬天-5度以下肯定要开furnace, 否则您的电费就起飞了。现在全加拿大只有BC省新房强制取消furnace。渥太华和BC能比吗？

不一定，现在技术零下5度不一定会比电费贵。
但是我以前分析了，最终看你的平均花费，就像跑1万米，你不可能每一米都比别人跑得快。
你零下5度之上省的钱超过零下5度之下因为用热泵的过度花费，你就值得换。

过渡季节可以用，零下5度就关停。

弄两个系统肯定不是最优解，有可能是最坏选择, 投资和维护维修花费可能会更高。如果电能搞定，干脆把气停了算了，换成电热水炉，即使不用，气的费用也挺高。
