1Copper Tubing And Air Conditioning
2Air conditioning is a combination of activities
such as conditioning the air i.e., heating or
cooling, ensuring air movement, and cleansing the
air. The cooling is just a part of the HVAC
(Heating, Ventilation and Air Conditioning)
system. Copper tubes help make HVAC effective
3About Copper Tubes
Copper is light, strong, and has a unique
property of heavy resistance to corrosion,
therefore it is preferred to be used as tubes to
supply hot and cold water. Also, copper tubes has
high thermal conductivity which is about eight
times that of Aluminum and thus is the most
preferred choice for air conditioning or
refrigeration. Coppers long lasting and
maintenance free characteristics make it the most
suitable choice for systems such as air
conditioning. The stringent requirements of the
air conditioning industry such as increased
operating efficiency and reduction or elimination
of harmful emissions have further increased
demand of copper tubing.
4Types of Copper tubes Soft copper and Rigid
copper are the two basic types of copper tubes.
The soft copper can be bent easily and is the
most suited for flare connection and thus is most
popularly used in the refrigerant line of the
split system air conditioner and heat pumps. The
rigid copper is a popular choice for water lines.
5 Copper Tubes in Air
Conditioners The direct expansion (Dx)
system of the Air Conditioner is directly
responsible for cooling by exchanging the heat
with refrigerant passing through tubes of finned
coiling coil. The evaporator of the Dx system is
made of cooling coil fabricated of copper tubes
and aluminum fins. Closed loop copper tubing is
also required in the heat transfer loop where a
refrigeration compressor moves the vapor
refrigerant to the condenser and returns it back
to the evaporator as a liquid refrigerant. The
chiller package the system also has a copper tube
or aluminum finned condenser coil and fan as the
condensing unit.
6One of the important components for proper
functioning of the Air Conditioner is the copper
tube. The copper tube, whether soft or hard
drawn, should be carefully chosen depending on
the width of the wall. Thinner wall is needed for
a tube of higher diameter. As the pipe is bent,
the wall thickness is reduced.
7Quality of copper tubes and maintenance of Air
Conditioners While purchasing a high price
consumer durable goods such as an air
conditioner, price is the most important factor
the customer considers, though a high priced air
conditioner does not guarantee a good quality.
The reliability of a product is the direct
product of the quality of the components used
such as the heat exchangers and compressors.
Quality can be ensured by a manufacturer though
in case the manufacturer produces the parts, at
least majority of them, by him.
8The tubes should be capped or sealed in order to
avoid moisture and foreign matter to enter the
tubes. The tubes should also be brazen with
Oxygen Free Nitrogen to prevent internal
oxidation of the tubes.
