Right, you are correct. Only the COP is given. Mhm okay... but in the heat pump consumption database at least supposed annual performance factors are listed
Oh yes, during screed heating I had an annual performance factor of 1.9
You are confusing COP and annual performance factor. Or did you heat the screed for a whole year ;p. My brine heat pump has a COP of about 4.8 at B0W35 but in reality a significantly higher annual performance factor. For air-to-air heat pumps, the annual performance factor is usually below the stated COP.
Look, just check what Cop means - do you maybe think that the performance factor, which is described by the annual performance factor, can only be displayed once a year?
Otherwise, feel free to call it MAZ, then it is correct for you.
Kehr, just look up what Cop means – do you mean that the coefficient of performance, which is described by the annual performance factor, can only be shown once a year?
Otherwise, feel free to call it MAZ, then it’s correct for you.
I know what both mean. The annual performance factor is the performance factor averaged over a year, Cop is an instantaneous performance factor, which is therefore given under certain operating conditions. Therefore, you can only specify an annual performance factor on a yearly basis; it is intended to compare the actual performance of a heat pump under the various occurring operating conditions. So what you said is something like "the average annual temperature was 14 degrees in May." Much higher than the average of past years... So just calm down, this isn’t a competition about who is most correct, but if you, as you posted above, point out that someone confuses Cop and annual performance factor, you should say it correctly yourself as a good example. Anyone can complain. Just look at your posts #41 and #43 here..
