如果heat pump取暖的房客抱怨溫度上不來。請跟他們溝通一下

 

Reduced Efficiency: As the outside temperature drops, the efficiency of a heat pump decreases. Heat pumps work by extracting heat from the outside air and transferring it inside. In very cold conditions, there is less heat available in the outside air to extract, making it harder for the heat pump to generate sufficient warmth.
Temperature Differential: Heat pumps operate by moving heat from a colder area to a warmer one. In extremely cold weather, the temperature differential between the outside air and the desired indoor temperature becomes significant. This makes it more challenging for the heat pump to extract and transfer enough heat to meet the heating requirements.

 

Most air conditioning systems can only handle a 20-degree difference between the outside and inside air temperatures.

 

熱泵是靠搬運室外能量加熱室內空氣。當環境溫度太低，沒有什麽能量可以往室內輸送，完全正常工作的機組也無能為力。emergency heating 是電阻式工作方式，功率有限。 任何房子都不是理想絕熱，天氣太冷，emergency heating杯水車薪，保持管路不上凍就很好了

• 在中國，湖南浙江江蘇這些冬天不常在零下的省份值得推薦熱泵式取暖。 -又當爹來又當媽- ♀ (148 bytes) () 01/17/2024 postreply 05:50:20

• 熱泵多用在冬天不是太冷的地區，不過有的房子隻有供電，除了熱泵沒有別的選擇。 -易木- ♂ (0 bytes) () 01/17/2024 postreply 06:20:33

• 順便問一下，為什麽同一個溫度，有些heat pump可以有些不行 -kitfrommars- ♀ (226 bytes) () 01/17/2024 postreply 06:27:20

• 有些heat pump裏麵有heat pack(就是電阻絲發熱），在外麵太冷的時候可以補充熱量 -徒勞- ♂ (0 bytes) () 01/17/2024 postreply 06:53:42

• Cold Climate Heat Pump 是可以的，零下20度都沒問題，出風口的溫度可達90度，如果有 -andy99- ♂ (53 bytes) () 01/17/2024 postreply 08:35:55
