如果heat pump取暖的房客抱怨温度上不来。请跟他们沟通一下

 

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.

 

热泵是靠搬运室外能量加热室内空气。当环境温度太低，没有什么能量可以往室内输送，完全正常工作的机组也无能为力。emergency heating 是电阻式工作方式，功率有限。 任何房子都不是理想绝热，天气太冷，emergency heating杯水车薪，保持管路不上冻就很好了

• 在中国，湖南浙江江苏这些冬天不常在零下的省份值得推荐热泵式取暖。 -又当爹来又当妈- ♀ (148 bytes) () 01/17/2024 postreply 05:50:20

• 热泵多用在冬天不是太冷的地区，不过有的房子只有供电，除了热泵没有别的选择。 -易木- ♂ (0 bytes) () 01/17/2024 postreply 06:20:33

• 顺便问一下，为什么同一个温度，有些heat pump可以有些不行 -kitfrommars- ♀ (226 bytes) () 01/17/2024 postreply 06:27:20

• 有些heat pump里面有heat pack(就是电阻丝发热），在外面太冷的时候可以补充热量 -徒劳- ♂ (0 bytes) () 01/17/2024 postreply 06:53:42

• 生产工艺，安装工艺可以产生天壤之别 -又当爹来又当妈- ♀ (0 bytes) () 01/17/2024 postreply 07:00:45

• Cold Climate Heat Pump 是可以的，零下20度都没问题，出风口的温度可达90度，如果有 -andy99- ♂ (53 bytes) () 01/17/2024 postreply 08:35:55
