A closed-loop heat-pump dryer: a DX coil that takes the water out of the drying chamber's own 55 °C air, the condenser in the same stream reheating it, a circulation fan — on a Copeland ZWD81KBC digital scroll (R134a, rated to 85 °C condensing) with its 10–100 % modulation declared. Nothing leaves but condensate. Run humidity-led in a building: steered on the chamber's humidity ceiling alone. Published as an example; the figures below are solved from this model.
A dedicated outside-air unit for a densely occupied room: an exhaust-air plate core, a wrap-around heat pipe around the chilled-water coil, winter heating and a supply fan. Published as an example — the figures below are solved from this model, not copied from a datasheet.
A heat pump whose source is a data centre's cooling loop: a coaxial evaporator on the 18 °C return water a CRAH sends back, a Danfoss VZH052 inverter scroll from the catalog with the maker's eighteen published speed steps setting its part-load power, and a coaxial condenser lifting a heating loop to 54 °C — the arrangement Seattle's Westin Building Exchange and the offices next to it run. The source is warm all year, so the machine works over a 40 K lift instead of an air-source unit's 50–60 K in winter, and the chiller behind it has that much less to reject. It serves no room; it holds its leaving water for whatever draws on it. Published as an example; the figures below are solved from this model.
A 12 HP-class VRF outdoor unit drawn as the frames of that size are built: a catalog inverter scroll and a catalog fixed-speed scroll on one circuit — a bank, the fixed machine running flat out as base load and the inverter trimming — behind a condenser declared from a 12 HP cabinet (980 × 1630 × 800 mm, 11 500 m³/h). Modulated to 33.5 kW the way the control runs it, it draws a maker's published power input within −9 to +3 % from 25 to 39 °C outdoor, the miss at the cool end, where a real unit runs its fixed scroll harder than the staging rule does. Published as an example; the figures below are solved from this model.
A chilled-water air handler for a campus building: outside-air damper with an economiser and a DCV floor, a chilled-water coil fed from the plant, a hot-water coil drawn as a gas boiler stand-in (fuel reported as gas at 85 %), a supply fan holding duct static. Published as an example; the figures below are solved from this model.
Midea's 8 HP V4+ outdoor unit as this model runs it — the first small frame: not the 20 HP machine scaled but a condenser declared from the frame's own cabinet (980 × 1630 × 800 mm, a coil wrapping three sides) and its published 11 500 m³/h, with the catalog inverter scroll at the frame's share of the 20 HP pair. Modulated to the rated 25.2 kW the way the control runs it, it draws Midea's own selection software's power input within ±1 % from 25 to 39 °C outdoor at the 100 % combination ratio, capacity falling past 35 °C as the grid does. Modelled from the maker's published data — not verified by the manufacturer. Published as an example; the figures below are solved from this model.
The smallest tower BAC publishes: a counterflow, centrifugal-fan, forced-draft unit rated to cool 36 USGPM of water from 95 to 85 °F at a 78 °F entering wet bulb. Drawn at the maker's own printed airflow (2.35 m³/s) and that rated water flow, this model reproduces the certified leaving-water temperature at the rated point exactly — the tower's NTU is derived from it. A centrifugal fan is what lets a Series V sit indoors or behind ductwork. Modelled from the manufacturer's published data — not verified by Baltimore Aircoil. Published as an example; the figures below are solved from this model.
A 600-ton counterflow Series V — centrifugal fans, forced draft, 1 800 USGPM cooled from 95 to 85 °F at a 78 °F entering wet bulb on 61.9 m³/s of air. Its liquid-to-gas ratio of about 1.6 is the highest of the five published here, which is why its derived NTU is the highest too: a counterflow tower works its fill harder per unit of air than a crossflow one. Modelled from the manufacturer's published data — not verified by Baltimore Aircoil. Published as an example; the figures below are solved from this model.
BAC's largest crossflow induced-draft range, here at 471 nominal tons: 1 413 USGPM cooled from 95 to 85 °F at a 78 °F entering wet bulb on 56.7 m³/s of air behind a 25 hp fan. At this size the tower is the plant's largest single air mover, and the fan motor is the figure that decides the condenser loop's part-load cost. Modelled from the manufacturer's published data — not verified by Baltimore Aircoil. Published as an example; the figures below are solved from this model.
The smallest evaporative condenser BAC publishes, drawn as a condensing unit: an R-22 Copeland ZR125KF scroll — 33 kW of cooling, sized under the condenser the way a unit with margin is — rejecting into a tube bundle under a recirculating spray, no fins, the air leaving saturated. Rated by its own sheet at 68.9 kW of base heat rejection on 3.32 m³/s of air — a condition the Series V EC sheet states, 105 °F condensing at a 78 °F wet bulb — and run as the evaporative wet coil with an isothermal tube side, the coil's share of the approach set where the maker's whole range derives. An open suction: couple any evaporator to it. Modelled from the manufacturer's published data — not verified by Baltimore Aircoil. 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 +1 to +4 % 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.
One indoor unit for the VRF outdoor unit beside it: a fan and a DX coil with both refrigerant ports open, fed across a refrigerant coupling. Four of these on one outdoor unit is a connection ratio of 100 %, which is where the makers rate them. Published as an example; the figures below are solved from this model.
A dedicated outside-air unit for a store: a sorption wheel between the exhaust and the outside air (humidity efficiency 65 %), a wrap-around heat pipe around a chilled-water coil, a gas reheat and a supply fan — the outside air dried where it enters, most of its moisture handed back to the exhaust before the coil sees it, so the rooftops can recirculate. Published as an example; the figures below are solved from this model.
A heat-pump dehumidifier for a pool hall: an eight-row DX coil that takes the water out of the hall's air, a reclaim condenser on the pool water that puts the heat the pool lost back into it first, the condenser in the air stream reheating with the rest — the hot-gas reheat every pool unit dries with — and a supply fan, on eight inverter scroll modules. Run humidity-led in a building: steered on the hall's humidity ceiling alone, the hall's temperature and outside air another machine's. Published as an example; the figures below are solved from this model.
A frozen-store unit cooler: a fan and a 6 fpi DX coil with both refrigerant ports open, fed by a remote low-temperature condensing unit (boundary.refFeeds on its own page; the pair pinned hourly in a building). Published as an example; the figures below are solved from this model.
A packaged rooftop for a VAV floor: outside-air damper with an economiser and demand-controlled ventilation, DX coil on an inverter scroll, an electric heater for morning warm-up, and a supply fan that holds a duct static as the boxes throttle; the boxes themselves live on the building. Published as an example; the figures below are solved from this model.
A closed-circuit cooler from BAC's Series V range: the loop fluid runs inside a coil under a recirculating spray and never touches the air, which is what a process loop or a heat-pump condenser loop wants. Rated on the same basis as the open towers — 168 USGPM cooled from 95 to 85 °F at a 78 °F entering wet bulb — on 13.8 m³/s of air from a centrifugal fan, with a 1 hp spray pump and 111 gal of coil. Run as an evaporative wet coil: air against the falling spray, the fluid against the air, the two conductances derived from the rating at the split and fluid-side flow exponent BAC's own Series V closed-circuit performance table picks — 4 and −0.6, the spray film outside the tube being much of the fluid side's resistance. Modelled from the manufacturer's published data — not verified by Baltimore Aircoil. Published as an example; the figures below are solved from this model.
A remote condensing unit on a Copeland ZF49K5E low-temperature scroll (R404A) with an air-cooled condenser and its fan: an open suction and liquid line, the load declared under boundary.refLoads (a unit cooler's, pinned hourly in a building). Published as an example; the figures below are solved from this model.
A crossflow, induced-draft tower — the fan pulls through the fill and its motor heat is added after, which is how this model wires it. Rated to cool 759 USGPM from 95 to 85 °F at a 78 °F entering wet bulb on 26.9 m³/s of air; a 15 hp fan motor. Series 1500 is BAC's induced-draft crossflow range from 92 to 747 nominal tons a cell. Modelled from the manufacturer's published data — not verified by Baltimore Aircoil. Published as an example; the figures below are solved from this model.
An operating-suite air handler: 40 % outside air, a chilled-water coil, an electric heater, a steam humidifier on boiler steam steered to the rooms' humidity floor, and a supply fan against HEPA static. Published as an example; the figures below are solved from this model.
A packaged rooftop unit: outside-air damper with an economiser, DX coil on four scroll compressors, a gas duct furnace at 80 % and a supply fan, on a two-fan air-cooled condenser. Its heat is gas — reported as fuel, never as electricity — which is what separates a rooftop's winter from a heat pump's. Published as an example; the figures below are solved from this model.
A liquid-cooled IT load and nothing but water between it and the outside: an immersion tank whose dielectric fluid is cooled by a coil-and-plate exchanger fed straight from a small evaporative cooling tower — no chiller, no air handler, no refrigerant, the arrangement the tank makers sell for data centres. The tank is a **liquid-cooled load**: 45 kW of servers declared as the load, the exchanger between the fluid and the water rated at a point the way a coaxial condenser is, and the solution reports the dielectric temperature the servers sit in — here 39 °C on a 35 °C / 25.6 °C wet-bulb design day, under the 45 °C limit declared. The tower is BAC's VT0-12-E at its published rating. Published as an example; the figures below are solved from this model.
An air conditioner that makes hot water from the heat it would otherwise throw away, the way a hot-water booster does it: a second, R134a heat pump whose evaporator is a plate exchanger on the A/C's hot gas. The A/C is a 20 kW-class split drawn from a supplier's own selection — coil faces, rows, fins, circuits and airflows, 7.5 K superheat and 5 K subcooling — on a Mitsubishi Electric LNB53 inverter rotary at its 60 rps rating speed. Between its compressor and its air condenser sits a **cascade exchanger**: the booster takes what the saturation difference across the plate drives, the air condenser rejects the rest, and the A/C condenses cooler for it. The booster's compressor is a catalog R134a heat-pump water-heater scroll standing in for the Mitsubishi SBB172, whose map is not published; its condenser heats water from 55 to 62 °C. The plate and the water side are an example's, not a maker's.
A crossflow, axial-fan, forced-draft tower from the middle of BAC's FXT range, rated to cool 390 USGPM from 95 to 85 °F at a 78 °F entering wet bulb on 18.1 m³/s of air. The fan sits ahead of the fill, so its motor heat is in the air the fill sees — which is how BAC builds an FXT and how this model wires it. Modelled from the manufacturer's published data — not verified by Baltimore Aircoil. Published as an example; the figures below are solved from this model.
