Hi users.
I wish you all good health.
I have a problem about my heat pump COP
I ' m examining the type 927 COP. When ı plot COP between 330h and 390h. The COP is about 3.3 but when i plot the COP between 0-740h. It shows that COP is going about 3.8 why this difference is occurred. I did not change anything
only changed the time interval.
Thanks
Have a good day for you all.
Emre.
