现在新房builder 喜欢搞全电,不用建煤气管道,省事省钱。LOL
全电的话Heat pump
还是有点用的,10月11月3月4月能省点电,1,2月直接关了就是了。

0F这种气温,heat pump做的事负功啊,全靠辅助电热丝

天然气都不够给力。实在太冷的时候烧木头最快

1000多尺的房子DollarMore 写了: 2025年 1月 8日 23:23 ----------------
廉颇去年响应 州政府绿色能源的号召,把家里的 oil burner 换成 heat pump 了,虽然我不情愿。
今年是第二个年头供暖了,发现出风口的风只是 lukewarm,得好长时间才能到 设定温度,而以前烧油时 热风很足很燥,随叫随到。
小房子,1000多尺,4吨的机器,按说大马拉小车了,应该轻轻松松采暖才对。
但实际情况是 加热很慢,机器一会儿转,一会儿停 (defrost 除霜),尤其最近几天外面温度15 - 20F时。
温度设在白天 61,睡觉 56,小孩儿回来 68,感觉蛮节省的,一个月电费得 2000 了。
每次去地下室看电表,都忽忽地狂转。
不知道哪出的问题。

电费$2000一个月?
你应该重新装一个heating system

是,就是所谓了逆卡诺,完全是骗人的,外面都零下20度了,逆卡诺完不成啊

分体式空调
窗式空调也算
都是一个原理
The theory behind a heat pump is that it uses electricity to transfer heat from a cooler space to a warmer space, rather than generating heat. This makes heat pumps more efficient than conventional heating systems, such as boilers or electric heaters.
Here's how a heat pump works:
Heating
During the heating season, a heat pump extracts heat from the outdoor air and moves it inside:
Liquid refrigerant passes through an expansion device, changing into a low-pressure liquid and vapor mixture.
The refrigerant goes to the outdoor coil, where it absorbs heat from the air and boils into a low-temperature vapor.
The vapor is compressed, which reduces its volume and causes it to heat up.
The hot gas is sent to the indoor coil, where the heat is transferred to the indoor air.
The refrigerant condenses into a liquid and returns to the expansion device.
Cooling
During the cooling season, a heat pump moves heat from inside the house to the outdoors.
Dehumidification
The cold evaporator collects moisture from the air, which dehumidifies the home.
Heat pumps can be combined with other heating systems, such as gas, in hybrid configurations. They are most efficient when the temperature is above 40°F, and they consume more energy when the temperature drops below that

用heat pump可不就这么多,一方面把冷气从外面搬进来,一遍还要用辅助加热,比光用boiler多花一倍的钱。哈哈哈哈

确实用的 oil burner 的 air duct,不想再多花一分钱 改造了。
另外,安装的时候 我发现有出的安排不合理,估计还得自己动手改造。。

malta 写了: 2025年 1月 9日 13:06 他家房子只有1000平方尺,4 ton heat pump。貌似确实没必要保留两套。我觉得他更应该查查管道,机器功率大,不等于送进来的热气多。他家说不定还是用的oil furnance的管道,不一定匹配。
