Final answer:
The outdoor temperature at which the heat pump provides the same amount of heat as the heat loss of the conditioned space without auxiliary heat is known as the balance point temperature.
Step-by-step explanation:
The outdoor temperature at which the heat pump provides the same amount of heat as the heat loss of the conditioned space without auxiliary heat is known as the balance point temperature.
This temperature is the point at which the heat pump is no longer able to meet the heating needs of the space and auxiliary heat sources, such as electric resistance heaters, are required.
For example, if the balance point temperature is 32 degrees Fahrenheit, and the outdoor temperature drops below this point, the heat pump alone may not be sufficient to keep the space warm and additional heating methods may need to be used.
