Dear Erik
Many thanks for your reply.
I have implemented your advice but the problem has not been solved.
It seems that changing two columns only substitute the cop and capacity ratios and could not be able to solve the problem of disconnection between chilled water set point temperature and ambient temperature with outputs (like COP).
With the old data file of COP and capacity ratios I have got result as below:
|
Input |
Output | |
|
Chilled water temperature set point |
Ambient temperature |
COP |
|
7 |
20 |
2.5 |
|
7 |
30 |
2.5 |

2.5 |
|
4 |
20 |
2.5 |
|
4 |
30 |
2.5 |
|
4 |
40 |
2.5 |
Substitution of cop and capacity ratio columns in data file and generating the new data file culminates in the following results
|
Input |
Output | |
|
Chilled water temperature set point |
Ambient temperature |
COP |
|
7 |

2.1 |

|

As you see there is no any connection between chilled water set point and ambient temperature with outputs.
Changing those two input parameters have not any effect on output COP?
I was wondering of any other comment and suggestion to solve the issue.
Many thanks
