Midea's 20 HP V6 outdoor unit as this model runs it: two catalog R410A inverter scrolls behind an air-cooled condenser, modulated to the rated 56.0 kW the way the control runs it, within +0.5 to +3.6 % of Midea's published power input from 25 to 35 °C outdoor at the 100 % combination ratio. Modelled from the maker's published data — not verified by the manufacturer. Published as an example; the figures below are solved from this model.

KeepRite's KEZA150L8, a two-fan air-cooled scroll condensing unit for a walk-in freezer, as this model runs it: the Copeland ZF49K5E its manual names — the catalog's own map, the low-temperature scroll the example freezer unit runs — on R448A, an air-cooled condenser on the cabinet's face, its fins louvered for the enhanced tube and fin the manual names, and the two fans (800 W) that draw air through it. The condenser's airflow is the one figure fitted, on the manual's R404A cell nearest AHRI 1250's freezer rating point (−20 °F suction on a 95 °F day, 53 100 Btu/h), and it stands for the condenser's conductance, not for air: the 10 080 cfm it comes to takes about three times the air power the printed fans could give through that coil, so the fans could not move it — read at the compressor's own rating basis, the tables ask more of the condenser than this model's coil gives behind those fans, as nearly every freezer table in the manual does. That same condenser holds all 162 cells the manual prints for this unit on R404A, R407A and R448A within −5.3 to +2.8 % (RMS 2.5 %). At −20 °F suction on a 95 °F day it gives 14.40 kW on R448A, against the 50 900 Btu/h (14.92 kW) printed. Modelled from the maker's published data — not verified by the manufacturer.

CTS's T-2100 — a T-2 cooling tower, 76 tons (336 kW): rated to cool 230 USGPM of water from 95 to 85 °F at a 78 °F entering wet bulb on 11.6 m³/s of air, the maker's own printed airflow, and drawn at those flows with an induced-draft fan on the leaving air, pulling through the fill. Open fill: the water meets the air directly — Braun's enthalpy-basis tower model. The model derives the machine's NTU from that one rated point, so it reproduces the rated leaving water exactly and predicts nothing else — one point per model is an input, not a validation. Modelled from the manufacturer's published data — not verified by Cooling Tower Systems. Published as an example; the figures below are solved from this model.

A variable-refrigerant-flow outdoor unit: two Copeland JPV066AC inverter scrolls on R410A behind an air-cooled condenser, with an open suction and liquid line so any number of indoor units can be coupled to it. Sized and held to a maker's published 20 HP capacity grid — it makes that maker's rated 56.0 kW from 25 to 35 °C outdoor within +0.5 to +3.6 % on power input, with the compressor at 0.62 to 0.70 of full output the way an inverter does. The design point below is the machine flat out, which is the larger figure — and it moves a few kilowatts with the property backend, which is why the advertised band is wide. Published as an example; the figures below are solved from this model.

Baltimore Aircoil's PCC-0046-0406N003 — a PCC evaporative condenser rejecting 279 kW at a 40.6 °C condensing temperature and a 25.6 °C entering wet bulb, on 6.3 m³/s of the maker's own printed air, with a 2.2 kW fan. The heat comes from outside the drawing, because that is what this machine is: heat rejection, and the plant that sends it the heat is the customer's. Given exactly the rejection BAC certify, the model solves the condensing temperature the machine settles at — which is the reading, and the only figure here that is ours rather than theirs. The rating condition is an inference and the listing says so: BAC's sheets never define the condition of their Base Heat Rejection.
