Re: [TRNSYS-users] this is weird about type 927

Emre,

The COP of the heat pump is only a function of the inlet conditions.  So if the COP is changing the inlet conditions are changing.  There really is no other explanation that I can think of.

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.
