⑤ Auxiliary Thermal Source:
In winter, circulating water temperature is maintained from 15 to 25°C. When in heating mode, the water
temperature will drop down gradually, so there should have auxiliary heating source to maintain the water
temperature in rating range. There are many types of auxiliary heating source, such as boiler, wasted heating
source from factory, or civilian steam system. Below diagram shows the piping work when system runs in heating
mode in winter.
