In this article I will show you how to calculate and design a heating pump with only few data. This calculation method is mostly used in existing buildings, because technical data is hard to find or not available at all. In a small example calculation I show you that the calculation of a heating pump is easier than you think. Afterwards we will design a heating pump using the example and choose the right model for our application.[Read more…] about Design of a heating pump with example calculation
The head of a heating pump is not as easily explained in one sentence as you might think – or maybe it is? Here is a definition attempt from Wikipedia:
“In fluid dynamics, Total Dynamic Head (TDH) is the total equivalent height that a fluid is to be pumped, taking into account friction losses in the pipe.” Total dynamic head – Wikipedia
I think this definition is a bit confusing and therefore I would like to explain the term “head” for pumps a bit easier.[Read more…] about What is pump head and why it’s important?
In this article I will introduce you to the portable air conditioner De’Longhi Pinguino PAC AN98 ECO. Currently there are two versions of the De’Longhi Pinguino PAC “98” ECO: the “Pinguino PAC AN98 ECO” (old version) and the “Pinguino PAC EL98 ECO” (new version). In this test I have tested the older version, but I will go into both versions and show the differences.
UPDATE 21.01.2021: The De’Longhi Pinguino PAC AN98 ECO (old version) has been completely replaced by the De’Longhi Pinguino PAC EL98 ECO (new version). The new version has only a few innovations and has almost exclusively improved in design, so many statements of this review can also be used for the new model.[Read more…] about Review: Portable Air Conditioner De’Longhi Pinguino PAC AN98 ECO
In this article I will introduce you to the portable air conditioner De’Longhi Pinguino PAC EX100 Silent. I have tested the portable air conditioner at the hottest summer temperatures over a longer period of time and would like to show you my experiences with the system here.[Read more…] about Review: Portable Air Conditioner De’Longhi Pinguino PAC EX100 SILENT
In this article, I introduce the Continuity Equation, explain why it is important to know it and show the context of the continuity equation with an example calculation. Since this article refers to the article on volumetric flow rate and flow velocity, I recommend you to read it as well.[Read more…] about Continuity Equation with Example calculation
