Correlation of
Air-Conditioner’s
Operation Status
and Pressure /
Running Current
What happens in comparison to normal values is summarized in the table below.
(Measured from 15 ~ 20 minutes or more after operation starts.)
When Cooling
When Heating
Notes:
P
∗
1. Water in the refrigerant freezes inside the capillary tube or expansion valve, and is basically
the same phenomenon as pump down.
P
∗
2. Dirt in the refrigerant clogs filters inside the piping, and is basically the same phenomenon as
pump down.
P
∗
3. Pressure differential between high and low pressure becomes low.
