Fan Coil Units
COOLING CAPACITIES0.8 kW to 9.5 kW
HEATING CAPACITIES1.0 kW to 11.8 kW
Fan coils units can be applied to two andfour pipe systems to
satisfy therequirements of a wide variety of airconditioning and
heating applications. Fancoils are used to directly treat the air
in theroom where they are installed.
The effectiveness of a fan coil is due to thelarge surface area
of the finned heatexchanger (coil), through which the air,drawn
from the room by the fan, passes.

SPECIFICATIONOperationCooling: the chilled water circulating in
the finned coil removes heat anddehumidifies the air passing
through the heat exchanger.
Heating: the hot water circulating in the finned coil supplies
heat to the air passingthrough the heat exchanger.
PerformanceThe performance of a fan coil can vary greatly with
changes in the temperature andin the amount of water circulating
through the coil, as well as with changes in thetemperature and in
the amount of air circulating through the coil.
The air volume is determined by selecting the proper fan speed
(MIN-MED-MAX),while the water flow rate is determined by the
specifications of the system and of thepump. Thermal performances
of the unit can be optimised by controlling the inletflow rate of
the water with proper regulating valves (ON/OFF, floating 3
points,modulating with proportional feedback), which can be
supplied as accessories.
For each model, thermal performances in heating and cooling
depend on thenumber of rows of the coil installed, which gives the
opportunity to make the airtreatment suit every condition
required.
In cooling function, under the same operating conditions, the
more rows the heatexchanger has, the more it will dehumidify.
Selection CriteriaThe optimum air treatment performance for the
room in question can be obtained bycorrectly selecting the
following parameters: size of the unit, number of rows in theheat
exchanger, inlet water temperature, water flow rate (or water
temperaturedifference).
Software SelectionTo facilitate choosing the correct size of a
fan coil for any operating condition(including those differing from
standard ones), YORK offers a dedicated computerprogram.

COMPONENTSChassis
The inner frame consists of 2 sides welded to a back panel and
aremovable condensate tray, suitable for both vertical
andhorizontal mounting units. The panels are made of
galvanisedsteel: 0.8 mm thick (sizes 110 to 218) and 1 mm thick
(sizes 220to 228).
The sides have a special anti-torsion structure near the
coilconnections to prevent deformation during pipeworkconnection.
All the inner elements are completely lined withthermal insulation
material.
The condensate water passes through a 20 mm externaldiameter
header to a field connected drain tube. Both right andleft drain
connections are available as standard.
Coils
The coils consist of aluminium fin packs and
mechanicallyexpanded copper tubes. Coils are factory leaked tested
at30 bar and suitable for working conditions of 8 bar.
Standard water connections, on the right side (facing the
airoutlet), have a " female threaded gas coupling. The coil can
beeasily removed and reversed on site for water connections onthe
left side. Each coil header is provided with a valve, to allowair
venting or water drainage from the coil.
Fans
The fan assembly consists of one (sizes 110 to 114) or two(sizes
216 to 228) centrifugal fans with aluminium impellers,directly
splined to the motor shaft, with galvanized steel
scrolls.Assemblies can easily be removed, independently of the
innerframe, by taking off two fixing screws. Each fan is
dynamicallybalanced, to reduce noise and wear of the components
tominimum levels.
The IP41 centrifugal motor, single or double-shaft, is
singlephase with permanently connected capacitor and
thermalprotection of the windings. The motor is factory wired as 3
speedor can be 6 speed (by using a transformer).
Controls
The control panel is fitted in an insulated box on the left side
ofthe inner frame, the panel must be moved to the right side
whenthe coil connections are reversed.
The control panel on YLV, YLV/AF and YLVR units contains a 3fan
speed selector and an ON/OFF switch. It is equipped with a0.3 m
long supply cable as standard and is accessed via a doorlocated in
the side of the grille.
The control panel on YLH, YLH/AF, YLIV, YLIV/AF, YLIH,YLIH/AF
and YLIVR units, contains a terminal board with themotor
cables.

Air filter
The air filter consists of a metal frame and two wide mesh
netsenclosing the filter element. The filter can be easily be
removedfor cleaning by releasing its fixing.
AF models have a shaped filter located behind the air inlet
paneland suspended by splines.
Housing
The housing is manufactured with sheet steel painted with
ovendried epoxy powders, 0.8 mm thick (sizes 110 to 218) and 1
mmthick (sizes 220 to 228). It is fixed to the inner frame with
screwsand retainers. On AF models, the filter access panel has a
quickrelease screw system.
Standard housing colours are white (RAL 9001) on the LASERseries
and ice white on the LOW BODY series.
The standard grilles are movable and can be turned by hand inall
4 directions. At each side of the grilles, two doors in ABS
giveaccess to the control panel and to the water
connectionsrespectively. The grilles and the two doors are finished
in white(RAL 9001).

* The sound pressure levels given are for a room volume of 100 m
at a distance of 1.5 metres from the unitwith a reverberation time
of 0.3 seconds.The values of Lp in the correction tables allow the
calculation of the new sound pressure level, when the room
volume,reverberation time and distance from the unit change.For
example: A YLV size 218 has a sound pressure of 41 db (A) in a room
of 100 m, at 1.5 m, reverberation time 0.3 s.In a room of 120 m, at
2.5 m, with a reverberation time 0.6 s, the sound pressure will be
41 + 1.2 - 1.0 = 41.2 db(A)

The flow rate correction and pressure drop correction factors
should be a applied to the nominal water flow rate and pressure
drop given in theperformance data to maintain the cooling/heating
capacties of the unit.
The capacity correction and pressure drop correction factors
should be a applied to the unit performance data for the nominal
water flow ratesgiven.
TABLE 27 Glycol Data
Example 1
The standard heating capacity of a YLV 218 2 row coil unit at
20C Air Entering Temperature, 70C Entering Water Temperature and10K
Water Temperature decrease at Fan Speed 3 (MED) is 6.826 kW with a
pressure drop of 3.5 kPa.
With a 30% ethylene glycol mix (external air temperatures down
to -10C, liquid frost protection to -16C) the corrected
heatingcapacity using a mean liquid temperature of 60C:
Heating capacity is 6.826 x 0.9426 = 6.434 kW
Pressure drop is 3.5 x 1.13 = 3.955 kPa
Example 2
The total cooling capacity of a YLV 224 4 row coil unit at 27C
DB, 19C WB Air Entering Temperature, 7C Entering WaterTemperature
and 5K Water Temperature Increase at Fan Speed 3 (MED) is 7.590 kW
at a water flow rate of 0.363 l/s with apressure drop of 7.7
kPa.
The total cooling capacity can be maintained with a 15% ethylene
glycol mix (external air temperatures down to 0C, liquid
frostprotection to -7C) using a mean liquid temperature of 10C:
Water flow of 0.363 x 1.0329 = 0.375 l/s
Corrected Pressure drop of 7.7 x 1.1181 = 8.6 kPa
