relay, needs repairing. Small problems often caused by short of refrigerant, this can be
judged by the ratio of operation condition together with the cooling effect. Long-time
operation with faults will largely increase power consumption and shorten the useful time
of your air conditioner and refrigerator as well.
Moreover, you can use the ratio of operation condition and the standby power to detect
and judge if your air conditioner and refrigerator is under normal operation, like described
in the operation manual (point 5 on page 8).
As is known to everyone, according to rooms in different size and different
environment conditions, you need to choose compatible air conditioners in different
power. If you choose one with larger power than you need, it will increase power
consumption and cause waste of power; if you choose one with lower power than you
need, it is difficult to achieve comfortable temperature even the air conditioner works day
to night. With compatible power, if environmental temperature is not too high, operation
condition of the air conditioner is not abnormal, and the operating temperature is set up
scientifically (that is set up by 5 to 7 degrees lower than environmental temperature.),
the ratio of operation condition will not be larger than 50%. Similarly, if environmental
temperature is not too high, refrigerating temperature is not set too low (that is to say it
is suitable for refreshment of the vegetables and fruits.), and the refrigerator is under
normal operation, the ratio of operation condition will not be larger than 30%.
Set up the ratio of operation condition and the standby power accordingly, if the
ammeter gives out alarm, you should firstly check the following situations: if doors and
windows are closed, if environmental temperature is much higher than before, or if the
air-conditioner’s temperature is set too low. If not, there may be some faults existed or
the air-condition needs refrigerant. The same as refrigerator, if there are no great
changes on working environment, but the ammeter gives out alarm, there may be some
faults or short of refrigerant. At this very moment, please check the real power and
comparing it with the power rating, then you can clearly know if refrigerant is needed.
Quick treatment is needed while the alarm is given out; Or else, the cooling effect of
air-conditioner or refrigerator will become worse and power consumption will also
increase.
