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.
Example14–26 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 |
|---|---|---|
| Face and bypass | splitter | 0.0 kW |
| Drying DX coil (chamber air) | dxEvaporator | 21.4 kW |
| Bypass mixing box | mixingBox | -12.4 kW |
| Reheat condenser (in the supply) | condenser | -28.3 kW |
| Circulation fan | fan | -0.6 kW |
| ZWD81KBC digital scroll | compressor | 7.2 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.
