On the page above it implies you can change emitter type for your water content calculation. I know the water content calc is just an estimation but how do you change your "radiator" to "other emitter" on Netsys? (This is for a heating system).
Also, what are these formula based on? Is there a standard that is used such as a British Standard?
Lastly, what type of emitters are comparable to "other emitter type"? I.e, is it suitable to estimate the water content of fan convectors or radiant panels, for example?
Currently I don't understand how a single formula can represent multiple emitter types in terms of water content.
Kind regards and thank you
Hi Toby,
I would suspect that "other emitters" refers to those for chilled water systems in this instance as the title of the article refers to that also. While for Netsys Heating the emitters could be viewed as being based on traditional radiator type emitters, much the same principles apply to the other types you refer to, and you should be able to approximate these by simply adjusting the pressure drop at that emitter, ie as below:
