Defrosting process will generate some water, which will
turn to water vapor.

noise will become weak 1 min later.
When the system is just started, the refrigerant is not
stable. About 30s later, the purr of the unit will dissipate.
It's the sound of 4-way valve switching direction. The
sound will disappear after the valve changes its direction.
It's the sound of gaseous refrigerant that stops flowing
and the sound of drainage system.
Because of temperature change, front panel and other
components may be expanding and contracting.
Because refrigerant suddenly stops flowing or changes
the flow direction.
Dust inside the units come out together with the air.
The room smell or the smell of cigarette comes out
through the units
