FAQ articles:
Second, use of air conditioning and consultation to
answer frequently asked questions:
(1) Air conditioning smell:
Use of air conditioning in the summer, in the
just-machine or shutdown, the machine may be the phenomenon of blow odor.
This is because when using the cooling function, the evaporator
condensate prone, adhesion of the dust in the air, resulting in a moldy,
the air smell. At this time, attention should be turned off before each
set to air conditioning mode (or higher temperature settings), so air
conditioning to work for 3-5 minutes, the surface of the condensate
evaporator drying on it. Air conditioning heating in the winter, when we
use the air conditioner will have some odor, or no light in the summer,
this is normal.
Heating in the winter when the air-conditioning, if any
odor phenomenon, please note the following when used:
1) If the number of normal filter cleaning smoke less or
more rooms, the odor filter network will increase
2) In daily use, as long as the time to clean the filter
(usually cleaned once every two weeks) or in the indoor spraying of some
of the inlet air freshener, that is,
Reduce this phenomenon.
(2) air conditioning condensation within the machine
outlet are:
Air conditioning in the refrigeration, condensation phenomena inside the
machine window has the following reasons:
1) remote control set temperature is low;
2) The ambient air humidity;
3) low-speed indoor speed settings;
4) the angle of the louvers to adjust properly for a long
time down wind or down swings, the louvers of the large temperature
difference between inside and outside, resulting in condensation
phenomena.
If the above phenomenon, please adjust the set
temperature, the temperature below 5 degrees below, if your indoor
humidity is high, set in the dehumidifying air-conditioning settings,
such as do not have this feature, you need to maintain ventilation;
Please set the same speed, high wind speed can reduce the condensation
phenomenon.
Air conditioning unit has dark spots within:
Anion air-conditioner used for a period of time, the
machine inside the machine near the surface and the walls are dark spots
appear, this is due to adsorption of negative ions in the environment
with the function of bacteria in dust, smoke, bacteria attached to the
filter network and on the ground, with a small amount of In the case of
metal surface, for a long time will have visible mold, but this is not a
failure, but not moldy.Therefore, please note that regular cleaning of
the outer surface of the air conditioner, clean the filter to clean and
maintain the cleanliness of indoor air, pay attention to ventilation can
often avoid this phenomenon.
Air-conditioning,
sound expansion and contraction:
Air-conditioning inside the machine run-time issue, "A
pair of clap" sound is due to thermal expansion and contraction caused
by plastic, this is not malfunction. Such as televisions and other
plastic changes in the structure and the internal temperature of
electrical appliances will have this phenomenon.
As air inside and outside the large temperature
difference, according to the principle of thermal expansion and
contraction will cause a slight plastic issued "A pair of clap" sound,
and that the better air-conditioning, air conditioning, the temperature
difference between inside and outside the greater, the plastic
deformation of the more obvious, so "A pair of clap" sound is also
relatively large.
The cooling effect is not good:
If the air conditioning work, but feel inadequate, please
check whether it is the following:
1) whether the regulation in accordance with the
requirements of operating the controller, set the temperature and wind
speed is appropriate: the right temperature 22-28 degrees Celsius, wind
speed, wind speed or low speed settings.
2) whether the dirty filter mesh: filter cleaned once
every two weeks
3) there is an obstacle in and out of air: the air inlet
and outlet that can not be placed item, affect the air-conditioning
cooling effect
4) Indoor has other sources of heat, or the room a lot of
people: the need to remove the heat
5) room with glass walls, indoor and outdoor heat
exchange fast.
(6) The heating effect is not good:
If the air conditioning works but it feels hot enough, please check
whether it is the following:
1) whether the adjustment operation of the controller as
required, set the temperature and wind speed is appropriate: the right
temperature 18-22 degrees Celsius, wind speed and set the stroke
2) whether the dirty filter mesh: filter cleaned once
every two weeks
3) There is an obstacle in and out of outlet
4) The reason the ambient temperature is too low (the
temperature falls below -5 ℃ below): the normal use of heating and air
conditioning ranges from -5 ℃ to +43 ℃, heating time, absorb heat from
the outside, and then sent to the room, when the outdoor temperature
very low, the absorption of heat is very limited, resulting in poor
indoor heating effect.
5) room with glass walls, indoor and outdoor heat
exchange fast
6) Check the power voltage is too low: below the supply
voltage less than 187V, air conditioning does not work or performance
decline.
The
air conditioner shut down frequently:
Air conditioner stop frequent reasons are:
1) the temperature set temperature and room temperature
is too small;
2) air conditioner, the wind outside the machine around
the object;
3) Room insulation effect.
For the above reasons is caused by frequent stops to open
the reason, it is because when the indoor temperature and set
temperature and the temperature difference between the outdoor ambient
temperature close to when this phenomenon is normal. At this point you
according to the required temperature, on the remote control to set the
appropriate increase or decrease the temperature 3-5 degrees, to reduce
the open air park frequent phenomenon.
Air conditioning voltage scope:
Fixed-frequency air-conditioning operation, the power
supply voltage range is 198-242 volts, lower than 187 volts or less will
not start. Inverter air conditioner operation, the power supply voltage
range is 198-242 volt, 150 volt inverter air conditioner can be started
when the ultra-low voltage, but not to normal operation (variable
frequency drive for variable frequency operation, power, current become
larger, the power supply due to too low results in low voltage
protection does not work)
(9) The air conditioner does not start:
Air conditioning does not start when you check the
following:
1) Power has power, whether the power failure;
2) Power plug is a good contact;
3) Remote control battery has power, such as lack of
electricity, transmission signal is weak, the indoor unit does not
receive;
4) remote control distance is too large, the signal
attenuation is more severe, the indoor receiver to receive bad.
Check processing:
1) Check whether the power supply voltage between 198-242
volts;
2), re-off power after 3 minutes and then test machine;
3), replace the remote control batteries.
(10) the use of remote control distance:
Air conditioner remote control use of distance, the
signal transmission when used on the indoor unit head aligned signal
reception window. Signal transmission between the head and the receiver
window (typically 30-60 degrees horizontal angle) in the 7 m distance
within the air-conditioner remote control, and not due to obstructions
to the normal reception of the work (the remote control The battery must
ensure that the capacity of normal)
Note: start with e-type fluorescent lamps, fluorescent
lamps or cordless phones convert the room, the signal receiver window to
receive the signal susceptible to interference, the use of distance as
long as the remote control closer to the indoor unit.
How long time do not air conditioner maintenance:
1) do not have air conditioners in a long time (seasonal
store) placed before the maintenance, in the sunny air condition, power
running about half a day, the air conditioning inside completely dry.
2) Turn off the air conditioner's power, or even if the
air conditioner is stopped, will consume some power.
3) clean the filter, loosen with a cloth indoor, outdoor
dust cover, conditions can cover the outdoor unit housing units.
4) for a long time do not remove the batteries when the
remote control, remove the battery if any appear, click on spikes with a
reset button.
Air conditioners in what circumstances need to add refrigerant
filling:
1) air conditioner installed in the normal air
temperature range (-7 degrees to 43 degrees), the normal effect of
cooling and heating, (air conditioner refrigerant refrigeration system
does not leak) refrigerants do not need to fill on a regular basis, if
the use of air conditioning in the normal sense of the temperature range
is not effective. Contact with manufacturers of home maintenance service
processing.
How
to maintain the remote control:
1) air-conditioning for a long time do not use the remote
control's batteries should be removed to avoid battery leakage and
corrosion of components within the broken remote control.
2) Use good quality batteries to avoid battery leakage
and corrosion broken remote control.
3) placed in remote areas away from the sun.
