What are the three major refrigerant lines?

The suction line connects the evaporator to the compressor, the discharge line connects the compressor to the condenser, and the liquid line connects the condenser to the expansion device.

Why are refrigerant lines different sizes?

The liquid line should be full of liquid with additional subcooling to prevent flashing due to pressure drop from the length, rise, fittings, and filter/drier. Because liquid refrigerant is much denser than vapor, the liquid line contains a relatively large amount of refrigerant compared to the much larger vapor line.

What size are AC refrigerant lines?

The diameter on the liquid line for standard residential systems is 3/8 inches in diameter. The suction line diameter is normally either 3/4, 7/8 or 1 1/8 inches, it depends on the size (and efficiency) of the air conditioning system or heat pump. Download Excel Sheet.

Why suction pipe is bigger than discharge in AC?

The discharge pipe may be larger than the suction pipe. The purpose of the lines is to keep the losses to a minimum. This is done to make sure there is enough Net Positive Suction Head available to meet the requirements of the pump.

Do refrigerant lines need to be insulated?

You typically don't need to insulate the high-pressure refrigerant line. You should, however, insulate the low-pressure refrigerant. Insulating the low-pressure refrigerant line will protect against condensation.

Why copper pipe is used in AC?

Copper as a metal has highly anti-corrosive properties compared to aluminium. During the cooling process, pipes comes in contact with air which causes oxidation within these pipes. Copper can better handle oxidation and corrosion for longer periods ultimately gives air conditioners a longer lifespan.

How long do copper refrigerant lines last?

Maximum equivalent length of line set is: a. 250 feet for single stage units with scroll or reciprocating compressors. b. 150 feet for single stage units with rotary compressors.
