Drake PAC360D3 (30 HP air-cooled scroll chiller, R407C) — modelled
Modelled from the manufacturer's published data — not verified by Drake Chillers. Source: Drake Chillers PAC360D data sheet (Pac360d-z+ref.pdf, Drake Refrigeration, Inc.) — the R407C performance table: tons and EER against leaving fluid from 35 to 65 °F and ambient from 80 to 105 °F, the two ZB114KCE named in the product information (docs/drake-chillers-source.json). The figures below come from this model run against that data; the manufacturer has not reviewed them. Are you Drake Chillers? Claim this page.

Drake Chillers' 30 HP packaged air-cooled chiller in its R407C build, as this model runs it: its own two Copeland ZB114KCE scrolls — the catalog's maps of the compressors its data sheet names — a stainless brazed-plate evaporator, and an air-cooled condenser under four fans. At 45 °F leaving water on a 95 °F day it makes the published 22.1 tons on 29.4 kW of compressor power — the sheet's EER of 8.44, on total power, less the fans — the two figures its evaporator and condenser are sized to; across the sheet's 45 °F row, 80 to 105 °F outdoors, it holds the published tons within 1.9 % and the compressor power within −2.8 to 0 %. The sheet holds its evaporator at one approach at every leaving temperature — it says the evaporator is selected upon requirements — so this fixed one makes up to 11 % more at 35 °F and about 14 % less at 65 °F. The PAC360D6 is the same machine on R404A. Modelled from the maker's published data — not verified by the manufacturer. Published as an example; the figures below are solved from this model.
