Hi All,
I am doing one building located in kochi when i checked
the ashrae it says that add 10F approach to WBT and compare it with
85F and which ever is lower take it as condenser water entering
temperature.

But there is no direct input available for condenser water entering
temperature input available are for WBT and approach suppose my WBT is
78F and i take 10F approach as mentioned in ashrae then my condenser
water temperature becomes 88F which is greater than 85F but i have to
take condenser water temperature as 85F only, because 88>85 as per
ashrae.Then my doubt is that i have to options to make condenser
water temperature 85 F

1: i should keep the WBT as it is same value ie 78F and reduce the
approach from 10F to 7F such that my condenser water temperature
becomes 78+7=85F or

2: i should keep the approach same as 10F and change the WBT from 78
to 75 such that my condenser water temperature becomes 75+10=85F

which way should i go .

Thanks
Sambhav
