WL16F1 Roof-Mounted Bus Air Conditioner — Component Deep Dive
Engineering analysis EA-WL16F1 | A component-by-component look at how the 4-evaporator / 3-condenser configuration delivers 18 kW for 7.3–8.2 m buses.
- Overview
- Recommended Products
1. The Architecture in One View
The WL16F1 is an FRP integral roof-mounted assembly for 7.3–8.2 m buses — city shuttles, tourist minibuses and light passenger fleets. Rated at 18 kW (61,416 BTU) with 3,200 m³/h evaporator airflow, it is built around a 4-blower evaporator / 3-fan condenser split that matches longer cabins and higher solar load.

3. Evaporator Section — 4 Blowers, One Balanced Core
The evaporator section drives 4 centrifugal blowers (ZHF283502) across a copper-tube / aluminium-fin coil. Four blowers — not two — is what keeps the rear rows cool on an 8 m cabin: airflow is delivered along the full duct length instead of dying out halfway.

4. Condenser Section — 3 Fans for Idle Performance
Three LNF273107C condenser fans push 7,200 m³/h through the parallel-flow aluminium condenser — the idle and low-speed airflow headroom that keeps discharge pressure stable in city traffic, where natural ram airflow is near zero.

6. Installation & Roof Opening
The WL16F1 shares the 16/18 F1 roof-cutting platform — one drawing covers both units. Supplied in PDF/DWG with every order.

7. Buyer FAQ
Q1. What is the difference between WL16F1 and WL18F1?
Same roof platform and fan count; the WL18F1 upgrades the compressor (JS38/FKX40-560K) and refrigerant charge for 20 kW peak capacity. Choose by cooling load.
Q2. What buses does the WL16F1 fit?
7.3–8.2 m buses and minibuses — city shuttles, tourist and light passenger fleets.
Q3. Is the compressor included?
Roof assembly or full kit with JS32 compressor, clutch, belt and lines — both options available.
Q4. What refrigerant does it use?
R134a with 2.6 kg factory charge.
Q5. How fast is delivery?
Stock units within 7 days; volume orders per production schedule.
