Fan coil is widely used in central air conditioning system
equipment, at the end of the specification is the full name of the
central air-conditioning fan coil units, can be simple
classification is as follows:
Central air-conditioning fan coil units shall, in accordance with
the form is divided into: horizontal dark outfit, horizontal load
and vertical dark, vertical installed Ming, cassette five;
Cassette fan coil units shall, in accordance with the presence of
condensate pump can be divided into: the ordinary type, luxury;
Horizontal fan coil according to thickness can be divided into:
ultra-thin, ordinary;
Central air-conditioning fan coil unit according to the size of the
static pressure can be divided into: 0 pa, pa 12, 30 pa, pa, pa 80,
50 is closed to static pressure;
Central air-conditioning fan coil number according to the exhaust
pipe can be divided into: two rows of tubes, three rows of tubes;
And the two control and four control points: two controls common
cold water cooling, fan coil summer winter go hot water
heating;More than four control fan coil is used for a few more
luxurious place, can go hot and cold water at the same time, can
according to need some refrigerating room, some room to keep warm.
The selection of fan coil units to note: fan coil sample abroad,
tend to give different closed under the static pressure of airflow
and cooling capacity, to facilitate users to choose.Although some
foreign concise sample only giving the name of air volume, but its
meaning is different from the standard in our country, it generally
refers to the air under a certain closed static pressure value, so
the name of the air volume of similar foreign fan coil units, air
volume will be 20% ~ 50% higher than domestic units.
Is also need to emphasize that using concise sample abroad, must
pay attention to foreign companies tend to implement different
standards and the meanings of the nominal volume also exist some
differences.So choose, it is best according to the latest sample
data is complete, or ask for delivery
Manufacturers to provide product under different closed static
pressure of cold air volume and value, to determine the
reliability.
Developed a variety of types of fan coil units: choose the fan coil
units, in addition to the cooling quantity meet the requirement of
the calculation of cooling load, also for the quantity of sensible
heat and latent heat of match to meet the requirements of the hot
wet room than;Must satisfy the supply air temperature difference
air volume, ventilation rate and air distribution, etc.Along with
the expanding the application range of the fan coil units, the
difference in the types of air conditioning room service also will
be more and more big.Requirements of the use of different
properties and different air conditioning room, hot wet ratio is
not the same, the amount of cold air volume matching should not be
the same.Even if the same room air conditioning requirements and
net volume, because of weather conditions, toward or differences,
such as palisade structure can also lead to the different cooling
load, clearly must be made with different structural
characteristics of fan coil units, to meet the different needs of
the room.And currently used in fan coil units, most is three rows
of tubes, each row of eight root canal of the same kind of form, is
clearly not meet the requirements of different rooms.Even if
required cooling load, may also lead to low load room room
temperature gradient caused by insufficient air volume and air
changes and volatility is too large, reduce air conditioning
accuracy and comfort;If you use the same air volume of the unit,
and may cause high room cannot be guaranteed due to lack of cooling
load temperature and humidity requirements.So different using
conditions and requirements of air conditioning room, should choose
different types of fan coil units, respectively.
Some experts advocate developing two rows of fan coil units, that
can reduce the supply air temperature difference and increase the
air changes, help to improve precision of the air conditioning and
comfort.Under the same amount of cooling, the use of small
temperature difference, big air volume air supply, will be better
than, large temperature difference air supply air conditioning
effect;Coil with a variety of waterway design.At present, the
production of three rows of pipe coil, regardless of the length,
all use the same SanJin for three out of the water.In order to
reduce water resistance, increase cooling capacity, different water
should be used in different length of coil design.As the carrier of
2 x 8 coil, respectively used two into two out, SanJin three out of
four and out three different and waterways.These ideas its essence
is to meet different processing requirements of the room, the
specific choice depends on applications.
Principle of fan coil units 1, fan coil system working principle:
fan, fan coil is mainly composed of heat exchange coil tube and
casing, according to the fan static pressure outside the pipe can
be divided into standard and high static pressure type, according
to the heat exchange coil tube row number can be divided into two
rows and three rows, so the heat exchange coil is usually adopts
copper pipe string of aluminum fin, copper pipe diameter for 10 to
16 mm, fin thickness is about 0.15 ~ 0.15 mm, spacing of 2.0 ~ 3.0
mm, generally adopts double fan into the wind before curved blade
centrifugal fan, motor USES capacitive 4 single phase motor, three
gear speed, casing and water plate heat coagulation.
requirements of temperature and relative humidity.Used in cold
water or hot water coil, the cold source and heat source supply.At
the same time, by focusing on fresh air after fresh air
conditioning room, through specialized fresh air pipe separately
for each air conditioning room, to meet the requirement of air
conditioning room.
Fan coil air conditioning system is compared with the centralized
system, there is no big wind, only the pipe and the smaller air
tube, has the arrangement and easy installation, being a small
architectural space, separate good adjustment, which is widely used
for temperature, humidity, accuracy is not high, room number, room
smaller, requires a separate control of comfort air conditioning.
Working principle of the fan coil control fan coil control with
local control scheme, divide into two kinds: simple control and
temperature control fan coil simple control: use three-speed switch
directly manually three-speed switch and start-stop control fan.Fan
coil temperature control: using temperature controller according to
the set temperature and actual testing temperature compare,
operation, automatic control electric two/three way valve open and
close;Three fan speed conversion.Or directly control the fan
three-speed switch and start-stop, thus by water or air volume
control system to achieve the purpose of constant temperature.
Fan coil structure of fan coil air conditioning system is composed
of fan and coil unit directly in the room, when the work coil
according to need to flow of hot or cold water, fan sucked into the
unit, the indoor air is filtered after coil cooling or heating
again after back to indoor, so in order to achieve the purpose of
adjusting indoor temperature and humidity.
1 overview, fan coil units, fan coil is widely used in central air
conditioning system of air processing equipment, is characterized
by compact structure, flexible use, easy installation, low noise,
low price, is a kind of applicable to different function building
comfort air conditioning universal equipment, due to the
performance of the fan coil is according to the design and
calibration of standard, when used in conditions of use a different
room, in the selection of fan coil units should be reduced and
fixed.
2, fan coil fan, fan coil structure is mainly composed of heat
exchange coil tube and casing, according to the fan static pressure
outside the pipe can be divided into standard and high static
pressure type, according to the heat exchange coil tube row number
can be divided into two rows and three rows, so the heat exchange
coil is usually adopts copper pipe string of aluminum fin, copper
pipe diameter for 10 to 16 mm, fin thickness is about 0.15 ~ 0.15
mm, spacing of 2.0 ~ 3.0 mm, with double inlet air fan before
curved blade centrifugal fan, motor USES capacitive 4 single-phase,
three gear speed, chassis and condensate plate heat insulation.
Fan coil installation design points
1, fan coil installation of condensed water outlet pipe should be
set up to the nearest tube drainage, which can shorten the distance
of horizontal drainage, reduce the water by the drain slope is not
enough, and risk of dripping.Lead to drain from the each fan coil
diameter with phi 20 advisable, and the size of the drainage riser
and manager also thrown.
2, in the fan coil units with hot and cold water pipes installed
over the manual and electric water valve should be set below the
water dish.The water dish plate connected with fan coil set water,
also can ask the manufacturer to the original water pan is longer,
to ensure that the valve such as the joint can condensate water pan
is along the discharge.Insulation and should be closed to prevent
secondary condensate.
3, fan coil installation should have access, its location and size,
concrete engineering with construction closely, talk things over
solve.Install fan coil units should be paid attention to in the
small condole top tear open outfit is convenient, because it is
necessary for the fan coil usage and maintenance.
4, fan coil installation inlet filter, to be loaded in order to
protect the plate clean, otherwise the heat exchange efficiency low
soon
5, pay attention to when will pick up on fan coil air duct, should
choose high static pressure fan coil equipment.
6, to indicate the installation position of water valve in order to
avoid reverse.Now a lot of engineering water valve upside to remind
don't put the "0" when the power supply wiring line is wrong, wrong
is going to burn out fan coil motor.
