A typical residential AC unit has two copper lines that both exit the building exterior and run to the outside condenser unit. Only one of these copper pipes, the cold line, should be insulated. This is called the “suction” pipe and is typically the larger of the two pipes.18 oct 2017
Do you have to insulate refrigerant lines?
If liquid lines pass through a space that is warmer than the refrigerant (i.e. the roof of a building at roof level), or if they could be considered hot enough to pose a safety risk, then insulation should be added.21 nov 2012

Should freon lines be cold?
When the system is operating, the large insulated suction line should be cold to the touch and sweating at any point where there is no insulation. The smaller uninsulated liquid line should be warm to the touch after the system has been operating for 10 or 15 minutes.26 abr 2007
Should Freon line be insulated?
The large, cold, low pressure line, carrying the evaporated refrigerant from the house, should be insulated to prevent condensation. The small, warm, high pressure line, carrying condensed refrigerant into the house, should not be insulated.

What type of insulation is used for refrigerant lines?
The ASHRAE Handbook recommends cellular glass, closed-cell elastomeric, closed-cell phenolic, polystyrene, and polyisocyanurate insulation for refrigeration system applications. These insulation types share a few characteristics: closed-cell structure, low water absorption, and low WVT.29 ene 2021
What is insulation in refrigeration?
Insulation performs a vital role in limiting heat gains in an industrial refrigeration system, ensuring that the compressor load does not become excessive. ... Insulation is also used to conserve energy, prevent condensation or ice formation and minimize corrosion.21 mar 2018
Does refrigerant piping need insulation?
Liquid lines generally are insulated. ... If liquid lines pass through a space that is warmer than the refrigerant (i.e. the roof of a building at roof level), or if they could be considered hot enough to pose a safety risk, then insulation should be added.28 jun 2021
Does AC drain line need insulation?
