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
