A direct-expansion split — indoor fan and coil, scroll compressor, and an outdoor coil behind a two-fan bank that stages down to hold head pressure in cool weather. Published as an example of what a supplier's system page looks like; its performance below is solved live from this model.
Example12–16 kW heating + coolingEUExample system. Published by HVAC Builder to show suppliers what their own page looks like. There is no company behind it and it is not a product offer — the specification is generic and the performance is solved from the model on this page.
Solved from this example's own model each time the page loads — the same numbers a supplier's page shows for their machine.
| Component | Kind | Duty |
|---|---|---|
| Outside-air damper: 10 % OA, economiser, 07–21 | damper | 0.0 kW |
| Return damper | damper | 0.0 kW |
| Indoor fan | fan | -0.2 kW |
| Indoor coil | dxEvaporator | 12.5 kW |
| Scroll compressor | compressor | 3.3 kW |
| Condenser fans (2) | fan | -0.5 kW |
| Outdoor coil | condenser | -15.7 kW |
Every air-coil refrigerant circuit here is reversible, so this machine is also a heat pump. Solved with the circuit running backwards at the standard air-to-air heating rating point — outdoor 7 °C dry bulb / 6 °C wet bulb, indoor 20 / 15 °C (EN 14511) — not at the supplier's own design conditions above, so the two ratings can be compared across machines.
