3. Poor efficiency explanation
During the process of using air conditioner, some phenomenon seems to be malfunction but actually not.
Thus when cooling or heating effect does not
achieve
to your expectation, the following factors have to be
ruled out
Phenomenon Causing explanation
High outside temperature and too many
people in the room, even air conditioner runs
at full-load operation, the wind blowing out
from air outlet is cold, but it is difficult to lower
the
indoor temperature, this is not
malfunction.
When the outdoor temperature is higher, more heat penetrates into
indoor space, which increases the cooling load of AC. If there are too
many people(for example 10) and each person gives off 120W, totally
1200W, this will running out of half of AC cooling capacity, and the unit’s
cooling capacity this time is far from enough, indoor temperature is hard
to lower down. It is normal phenomenon and do not mean useless of
AC.
Power voltage is too low, causing AC uneasy
to start and shut down after starting, or fuse
be burned out etc.
If the electricity net voltage is too low, user should load a power
manostat to keep voltage between 220V-380V for AC normally running
Select high wind speed but indoor
temperature still at high side, air flow from the
air outlet is too weak.
It is because air filter is too dirty or blocked making cooling capacity fail
to be brought by air flow, causing cooling capacity inadequate. Take out
filter and wash, the problem will be solved.
Select high wind speed, the vibration and
sound of unit are severe. Fan runs at high speed, severe vibration and sound of unit is normal
phenomenon
Temperature controller adjusts improper and
max
cooling capacity is not utilized
completely, thus indoor temperature can’t
lower down.
Check the temperature controller, and problem will be solved.
As for Heat pump air conditioner heating
effect is not ideal during cold winter, this is
normal phenomenon.
The lowest temperature is
－
7
℃
when heating, below this temperature
unit cannot heat effectively.
