OBJECTIVES:(kindly fill this with 3 objectives which you
think is important for the student to learn in this topic)

 Be familiarized with the different tools and materials.

 Understand their function as well as their proper uses.
 Retain the knowledge through continuous studying of the subject.

MATERIALS:
CAPACITOR
 The capacitor is a passive component that stores electrical energy in the form of a
magnetic field. Capacitance is the term for the capacitor’s effect. It consists of
two closely spaced conductors separated by a dielectric substance. When the plates
are linked to the power, the electric charge builds up on the plates. The positive
charge is accumulated on one plate, while the negative charge is accumulated on the
other.
 Electrolyte capacitors are
typically utilized when
Electrolytic Capacitor large capacitor values are
required. A thin metal film
layer is utilized for one
electrode, while a semi-
liquid electrolyte solution
in jelly or paste is applied
for the second electrode
(cathode). The dielectric
plate is a thin layer of
oxide that is
electrochemically produced
in manufacturing with a film
thickness of fewer than ten
microns.
Paper was applied in
between the two foils of
Paper Capacitor the capacitor in the
beginning, however, these
days, different materials
such as plastics are
utilized; therefore, it
is referred to as a paper
capacitor. The paper
capacitor has a
capacitance range of
0.001 to 2.000
microfarads and a voltage
range of up to 2000V.

The silver mica

capacitors use the
Mica Capacitor dielectric, which is made
up of a set of natural
minerals. Clamped
capacitors and silver
mica capacitors are the
two types of mica
capacitors. Because of
their poor performance,
clamped mica capacitors
are deemed outdated. The
silver mica capacitors
are made by sandwiching
mica sheets with metal
coatings on both sides
and encasing them in
epoxy to protect them
from the elements. The
mica capacitors utilized
in the design require a
tiny, stable, and
reliable capacitor.
 The plastic foil
capacitor is non-
Non-Polarized Capacitors polarized by nature, and
electrolytic capacitors
are often two capacitors
in series, back to back,
resulting in a
nonpolarized capacitor
with half capacitance.
The AC applications in
series or parallel with
the signal or power
supply are required for
the nonpolarized
capacitor.
Film capacitors are
capacitors with a thin
Film Capacitor plastic dielectric as the
dielectric. Using a
sophisticated film
drawing method, the film
capacitor is made
exceedingly thin. If the
film is made, it can be
metalized depending on
the capacitor’s
qualities. The electrodes
are added and assembled
to guard against the
environmental factor.
Ceramic capacitors come
in a variety of designs,
Ceramic Capacitor including ceramic tube
capacitors and barrier
layer capacitors, which
have become obsolete due
to their size, parasitic
effects, or electrical
properties. Multilayer
ceramic capacitors (MLCC)
and ceramic disc
capacitors are the two
most prevalent forms of
ceramic capacitors.

COPPER TUBE

 Copper tubing is most often used for heating systems and as

a refrigerant line in HVAC systems. Copper tubing is slowly being replaced
by PEX tubing in hot and cold water applications. There are two basic types
of copper tubing, soft copper and rigid copper. Copper tubing is joined
using flare connection, compression connection, pressed connection, or
solder. Copper offers a high level of corrosion resistance but is becoming
very costly.
Soft Copper Tube Soft (or ductile) copper
tubing can be bent easily
to travel around
obstacles in the path of
the tubing. While the
work hardening of the
drawing process used to
size the tubing makes the
copper hard or rigid, it
is carefully annealed to
make it soft again; it
is, therefore, more
expensive to produce than
non-annealed, rigid
copper tubing. It can be
joined by any of the
three methods used for
rigid copper, and it is
the only type of copper
tubing suitable for flare
connections. Soft copper
is the most popular
choice for refrigerant
lines in split-system air
conditioners and heat
pumps.
Rigid Copper Tube Rigid copper is a popular
choice for water lines.
Rigid or "Hard" copper
tubing is generally
referred to as "pipe".
Copper "piping" is
referred to by nominal
pipe size, or the inner
diameter. It is joined
using a solder/sweat,
roll grooved,
compression, or
crimped/pressed
connection. Rigid copper,
rigid due to the work
hardening of the drawing
process, cannot be bent
and must use elbow
fittings to go around
corners or around
obstacles. If heated and
allowed to cool in a
process called annealing,
rigid copper will become
soft and can be
bent/formed without
cracking.
FILTER DRIER

 Filter driers are devices used in a HVAC system that are a combination of

filter and dryer (or drier). A filter is used to remove any particle such as
dirt, metal or chips from entering the refrigerant flow control. The
refrigerant flow control device could be thermostatic expansion valve or
simply a capillary tube.

Liquid Line Type is placed after the

condenser coil and before
the expansion valve. The
liquid refrigerant that
flows from the condenser
to the expansion valve is
filtered from particles
and moisture before
entering it. Good filter
will filter out particles
that are 20 micron or
above from the system.
Suction Line Type is placed after the
evaporator and before the
compressor. This device
is used to protect the
compressor especially
after any failure that
contaminates the system.
