Why does the air conditioner outdoor pipe joint freeze and freeze in case of refrigeration?
Fluorine slightly more: thick pipe icing or frost, because the refrigerant inside the machine is not completely vaporized, back to the end is still vaporized heat absorption.Excessive dust in the inner filter screen or evaporator: the internal air circulation is not smooth, resulting in the backflow of the subcooled refrigerant, the icing of the thick pipe, and the cooling effect.
Lack of fluoride: the tube frost, because the refrigerant has begun to vaporize here, into the internal machine has lost part of the heat absorption capacity of vaporization, air conditioning cooling effect worse.
Normal: a thin tube (pressure pipe) cool or lukewarm, thick tube (tube) cool or cold dew.
