Welcome, sorry for the confusion we use TR in Phils as abbreviate for Tons of Refrigeration.
Here is my equipment break down used in the project for your reference.

Hope this helps I'm from Philippines..
I got a 524 HP Project last year using HITACHI VRV we call it SET-FREE roughly 437TR. Using CIF (no duties and taxes) price for the Equipment and local installation cost (vat-able) its around 1,400USD/TR.
Note: Equipment was brought directly from Japan...
