<div>Well, the baseline COP are measured at standard testing conditions. So i am not debating the fact the COP would be constant. I just needed to know that what does increase in 25% efficiency actuallu mean. I personally thought having a chiller whose kw/ton was lower than that recommended by ASHRAE 90.1 would be good. Needed to confirm that.</div>

<div>Thanks for the input<br><br></div>

<div dir="ltr" align="left"><span><font color="#0000ff" size="2" face="Arial">Maybe you can tell me what the COP of a chiller means then, given that it varies with load, how do you come up with a single COP for a chiller? Or is it just the average COP given the operating conditions that the chiller experiences? Or are you talking about the integrated part load value? </font></span></div>

<div>I had a confusion that you all might be help out.</div>
<div>When someone says that they want a chiller with 25% more efficiency than the baseline dictated by ASHRAE 90.1, does it mean the COP should be 25% greater?<br>-- <br>Thanks<br><br>Sincerely,<br>Amit Bhansali, M.S. , EIT<br>
