Keywords:

heat flux; temperature field


Abstracts:

In article developed methodology allows to determine the heat flux size from tube surrounding environment to the heat carrier (liquid in tube with a low boiling temperature). Such an operation principle is realized in heat pumps. Heat flow is generally declines over time as the environment temperature falls. In article obtained mathematical expressions allows to determine a reduction of flows, temperature field changes in the environment surrounding the tube and in whole system. Obtained expressions allows to identify and predict the heat pump output changes at the time.
