Yilaide WA concealed horizontal fan coils

Keep coil-row count, static-pressure option and model suffix together; the original tables contain both useful test conditions and unresolved entries.

01 / UNDERSTAND THE EQUIPMENT

Select the WA ducted terminal without mixing its schedules

Yilaide’s concealed horizontal fan-coil page includes separate WA two-/three-row schedules and an additional WA-YC table. The original images distinguish coil configuration, outlet-static-pressure options and electrical/noise entries. One combined family brief keeps those differences visible; model capacity, coil-row count and pressure rows are not multiplied into thin pages.

For FP-85WA, the two-row high-speed entry is 860 m³/h and 4.01 kW cooling, while the three-row entry is 850 m³/h and 4.50 kW. The published cooling test condition is 27°C dry bulb/19.5°C wet bulb entering air and 7/12°C water. Heating uses 21°C entering air and 60°C or 45°C inlet water at the cooling flow. Confirm the exact coil and pressure configuration, because the same short model label does not settle all performance and installation options.

Manufacturer-published values · conditions are part of the specification
Parameter	Published value	Conditions and evidence
FP-85WA two-row versus three-row cooling	Two-row: 860 m³/h, 4.01 kW; three-row: 850 m³/h, 4.50 kW high speed	27°C dry bulb/19.5°C wet bulb air; 7/12°C water. Separate coil configurations, not a single merged row. Source
FP-85WA water duties	Two-row: 706 L/h, 27 kPa; three-row: 780 L/h, 30 kPa	Cooling-specific original rows; selected valve/branch losses additional. Source
FP-85WA two-row pressure options	12/30/50 Pa outlet static: 74/86/97 W; 42/44.5/47 dB(A)	Source ties electrical/noise rows to outlet-static entries. Intended fan speed for those entries needs issued selection. Source
Sound evidence and anomaly	Page says sound pressure tested in a semi-anechoic room; FP-85 three-row image lists 43.5/37/32 dB(A)	Original values decrease across 12/30/50 Pa rows, unlike many adjacent entries. Retained as unconfirmed source data. Source
Mechanical reference for FP-85WA	Drawing: C length 925 mm, W 452 mm, H 232 mm; outlet 725 × 150 mm	Lettered drawing includes additional tray/connection positions; table height alone is not the service envelope. Source
Alternative WA-YC table	Same page provides a distinct suffix and different input/efficiency rows	Model/motor equivalence not established; never substitute its low input values into WA schedules. Source

Selection and application review

Freeze coil rows and operating speed before comparing duty

The FP-85 two-row schedule has 860/645/430 m³/h and 4.01/3.21/2.41 kW cooling at high/medium/low speed. The three-row schedule has 850/638/425 m³/h and 4.50/3.60/2.70 kW. Identify the actual coil row and intended speed in the enquiry rather than requesting only ‘FP-85’.

Require a current selection at the room and water conditions. The stated 60°C and 45°C heating conditions are different outputs, not a guarantee at any hot-water supply temperature. No sensible-capacity split is provided in the reviewed image, so latent/sensible load fit needs additional supplier evidence.

Use the duct resistance and outlet-static option together

The page explicitly calls static pressure the unit’s outlet static pressure, and the schedules include 12, 30 and 50 Pa options. Provide the external duct/filter/damper resistance and the return/discharge arrangement. Ask for the selected operating airflow and pressure basis; do not treat a maximum airflow row and any pressure option as automatically compatible.

The electrical/noise entries change across those pressure rows. Obtain the actual selected fan/motor schedule and control method. Terminal efficiency entries are not a whole chilled-water plant COP, and the separate WA-YC input values are not substitutes for the ordinary WA configuration.

Close the sound and transcription questions

The page attributes sound-pressure testing to a semi-anechoic room under GB/T 19232-2019. A room sound level still depends on the installation and duct path. Request current comparable sound evidence for the chosen speed and pressure option.

The FP-85 three-row source lists 43.5, 37 and 32 dB(A) across its pressure rows; the pattern differs from neighbouring rows and the two-row schedule. Another heating entry also needs confirmation. Preserve the original file and obtain an issued correction/revision rather than silently repairing values or presenting these questionable entries as a quietness guarantee.

Approve the complete concealed assembly and maintenance access

Use the current dimensional drawing for mounting, coil connections, return box option and outlet transition. The original FP-85 drawing gives a 925 mm length, 452 mm width and 232 mm table height, but the drawing also shows tray/connection projections and different lettered dimensions. Confirm their datums and the installed service space.

The schedules distinguish weight with and without a return box. Close the actual supplied assembly, filter/access location, valves and drain connection. A narrow chassis dimension does not reserve enough space to remove the motor, coil or control components.

Accept the selected coil and pressure configuration

Issue the room load, required speed, water temperatures/flow, duct resistance, return arrangement, valve and control scope. Obtain the exact model/suffix, coil rows, current table and drawing revision with the quotation.

Agree thermal/hydraulic checks at stated conditions, electrical/noise evidence at the selected pressure option, and installed condensate/control checks. The manufacturer’s page says the unit nameplate governs actual parameters; obtain that current schedule before ordering. No price, stock, delivery or installed performance is verified here.
