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
odour. This is because when using the cooling function, the evaporator
condensate prone, adhesion of the dust in the air, resulting in a
mouldy, 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
odour phenomenon, please note the following when used:
1) If the number of normal filter cleaning smoke less or
more rooms, the ouder 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
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
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
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 mouldy. 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.
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
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
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
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
6) Check the power voltage is too low: below the supply
voltage less than 187V, air conditioning does not work or performance
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
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
