Improper set of temperature
Adjust set temperature
If cooling (heating) load is
proper
Check the forecasted load of cooling (heating)
The refrigerant has leakage or is
insufficient
heck and fill the leakage, then
vacuumize it and supplement the re-
frigerant as required
Leakage between the high pres-
sure and the low pressure in-
side the compressor
Replace the compressor
Malfunction of four-way valve
Replace the four-way valve
Local block of capillary
Replace the capillary
Blockage of cooling system
Judge whether the system is blocked by
observing the condensation of evapora-
tor and the pressure value of the high
pressure manometer and take measures
to deal with the system.
Malfunction of
r e f r i g e r a n t
flow
Heat insulation for the connection
pipes of the indoor unit and the out-
door unit is bad.
Make sure that heat insulation for the thick and thin pipes
is good. Heat insulation must also be provided for the
joint andthe exposed part of the copper pipe .
Block of outdoor heat ex-
changer
Clean the dust accumulated on the surface of
the heat exchanger.
Air filter were blocked
Clean the filter
Fan speed was set too slow
To set the fan speed to high or
middle speed
Air circulation
is insufficient
Fan rotation speed becomes
low
Capacitor
damage
Motor damage
Replace the capaci-
tor
Replace the motor
The installation position of the
outdoor unit is not appropriate.
Good ventilation must be provided for the
installation position of the outdoor unit.
The outdoor temperature is too high.
Properly install the rainproof plate or the sunproof plate. If the
maximum cool air still can not meet the requirement, it is sug-
gested to replace the air conditioner.
Keep certain air tightness indoors, try not to use
electricalappliance with large quantity of heat
The air tightness is not enough. People
come in and out too frequently. There
are heating devices indoors.
Poor COOL(HEA
