The temperature difference, also known as the temperature spread, indicates the difference between two temperature measuring points. An example of this is the temperature difference in a heating system between the flow and return temperatures. The temperature difference (delta theta) is specified in Kelvin K. Example: Flow = 90 ยฐC, return = 70 ยฐC, delta theta = 20 K.
Hydronic Balancing DIY โ Step 5: Volumetric Flow Calculation
[latexpage]In the fifth step of the"Hydronic Balancing DIY" series, we will calculate the volumetric flow for each radiator in the example building. In the previous steps for hydraulic balancing, we recorded all the important data and can now process it. Tip: You can...
