[Equest-users] Fw: Daikin Curves for eQuest

[Rakesh Desai]

Paul,

 

I am confused about curve preparation.

 

For what capacities and what temperatures, we should prepare curve and how
to find out coefficients?

 

Is it possible to demonstrate with the details you had attached?

 

Rakesh

Rakesh:

You can get the performance data for Daikin from their design manuals.  See
sample attached.

They provide enough information in their manuals for you to build a curve
for the cool capacity f(EWB,ODB), the cool eir f(EWB,ODB), the heat capacity
f(EDB, OWB) and the heat eir f(EDB, OWB).

Dear Team,

 

I am modeling Diakin VRF system. Does anyone have similar details?

 

With best regards,

 

Rakesh Desai

Paul,

 

Thanks for posting this to the list.  I can only hope more manufacturers
will follow suit with guidance documents for modeling their products.

Paul,

 

I just noticed our earlier dialogue and realized that you are doing energy
modeling in eQUEST.  Mitsubishi recently put together the attached
application note for guidance in modeling VRF in this software (also
attached is a .inp file and a .pd2 file with the heating/cooling partload
curves already entered).

Joe:

 

I wonder if you can help me out.  I am looking for the performance data for
a PUHY-P1500-YSHM-A.  I want to write the custom curves for this unit.  I
guess it is not sold in the USA?  This is a project in another country.

 

Thank you,
