[Equest-users] VRF in eQuest

[Carol Gardner]

Pasha,

Here is the info you needed for your VRV project. I'll send it via this
email as others may need similar data:

I have included some input data below for the units you requested.  I have
given you the data in EIR form as that is what gets put into Equest and I
figured it would save a step.

Here is the data I would enter for the systems:


*Outside Units*

PURY-P234TGMU-A

Cooling EIR: .315 Heating EIR: .294

PURY-P72TGMU-A

Cooling EIR: .307 Heating EIR: .271

PURY-P144TGMU-A

Cooling EIR: .336 Heating EIR: .291

PURY-P108TGMU-A

Cooling EIR: .307 Heating EIR: .282

*Inside Units*

PKFY-08 - .14watts/cfm

PKY-12 - .08watts/cfm

PKY-15 - .08watts/cfm

PKY-024 - .06 watts/cfm

PKY-30 - .07 watts/cfm

Let me know if this works for you or if you need additional info,

Cheers,

Carol
