Refrigerant line insulation is partially responsible for the efficiency of your air conditioning system operation.
Refrigerant line insulation thickness.
Liquid lines generally are insulated.
Overall this is good news giving mechanical insulation an opportunity to contribute to greater building energy efficiency.
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.
If it was all vrv vrf manufacturer s would require 2 1 2 on the high pressure lines.
They are warm to hot 110 f 43 3 c for air cooled.
In our photo at above left where refrigerant line insulation is incomplete the drip stains on the attic floor may well indicate a point at which leak.
There is a double suction riser on one of the circuits.
1 4 5 8 insulated copper coil line set seamless pipe tube for hvac refrigerant 1 2 white insulation ez twin set 35 long 167 99 167.
2 hot pipes require.
The thickness required for low temperature pipes like refrigerant and chiller water is less than higher temperature pipes and smaller pipes require less insulation as well 1 in general refrigerant suction lines and chilled water pipes require either 1 2 or 1 insulation depending on the size and temperature of the pipes.
If liquid lines pass through a space that is warmer than the refrigerant i e.
This also applies to the need for epdm on insulated coils line sets going to the fan coils.
To determine the vrf refrigerant insulation requirements you will need to know several things to.
In typical conditions a 1 inch thickness is the standard.
What are the new pipe and duct insulation thickness requirements in standard 90 1 2010.
Pipe insulation thicknesses are greater than or equal to those in the 2007 standard but duct insulation thicknesses have not changed.
Missing or damaged refrigerant line insulation insulation on the refrigerant lines particularly on the larger suction line will cause condensation and drips from the lines in humid areas.
However in some cases where humidity is high over 80 percent a 1 inch thickness may be used.
Two different diameter copper refrigerant lines one approximately 1 4 second 3 4 diameter depends on your system size and distances run between the air conditioning system condensing unit house exterior and the ac coil a coil named after its shape.
Mandated changes in refrigerants are resulting in colder line temperatures which require increased insulation thickness to prevent condensation.
