What is air conditioner
evaporator?
Air conditioner evaporator is a
heat exchange. It takes in low
temperature, low-pressure liquid
refrigerant from the expansion
device and changes it into low-
pressure, low temperature vapor
refrigerant.
Evaporator coil is the
components that add heat to the
air conditioner units.
* Notes: refrigeration is the
process of removing heat from
one area where it is undesirable
to an area where it is not
significant. For this process to
work heat has to flow from one
area (medium) to another.
To make heat flows, one of the
mediums has to be at a higher
temperature. Since, heat always
flows from a high intensity to a
low intensity.
Types of air conditioner
evaporator:
Director-expansion or Air-cooled
Evaporator
1. Flooded evaporators
How does air conditioning
evaporator works?
Air conditioning evaporator
works by absorb heat from the
area (medium) that need to be
cooled. It does that by
maintaining the evaporator coil
at low temperature and pressure
than the surrounding air.
Since, the AC evaporator coil
contains refrigerant that absorbs
heat from the surrounding air,
the refrigerant temperature must
be lower than the air.
The expansion device provides a
pressure reduces between the
high side and the low side of the
system, the saturation
temperature of the refrigerant
entering the air conditioning
evaporator is lower than the
medium to be cooled.
One of the characteristic of a ac
refrigerant is that as the
pressure is reduced the boiling
point is also reduced. Therefore,
as the pressure is reduced
through the expansion device so
is the point at which it will boil
and become a vapor.
As the warm air from the space
passes over the evaporator coil,
it gives up its heat to the lower
temperature liquid/vapor
mixture passing through the
evaporator. As the liquid
refrigerant absorbs this heat it
boils changing from the liquid
state to the vapor state.
The amount of heat the air
conditioner evaporator absorbs
must equal the amount of heat it
lost
For instance, if the air
conditioning evaporator gives
up 100 Btu’s of heat to the
surrounding hot air, then the
refrigerant within the air
conditioning evaporator coil
must gain 100 Btu ’s of heat.
The amount of liquid entering
the evaporator must be enough,
so by the time it reaches the end
of the evaporator. It will be
completely boiled to the vapor
state.
There must be enough air flows
across the AC evaporator coil to
provides heat to the refrigerant
in the evaporator coil. This is just
a safety way to ensure the air
conditioner compressor doesn ’t
have the liquid refrigerant
entering it.
Air conditioning evaporator
picture above tells us what
happen to the evaporator coil.
The air conditioning evaporator
coil absorbs heat into the
refrigerant from the warmer air
passing over the surface of the
evaporator coil. The heat
absorbed causes the liquid
refrigerant to boil, changing it
from a liquid state to a vapor
state.

What are air conditioner
compressors?
Air conditioning compressor is
the heart of the air conditioner
units. It’s the mechanical
components that use electricity
and capacitor as the single
energy source to operate it.
The air conditioning compressor
is the ac parts that cause the air
conditioner refrigerant to flows
in a cycle.
What are the types of air
conditioning compressors?
There are five main types of air
conditioner compressors:
1. Reciprocating
2. Rotary compressor
3. Centrifugal compressor
4. screw compressors
5. Scroll compressors
All five groups of air conditioner
compressors work the same
way, but their internal methods
of compressing refrigerant
vapors are different.
The most common compressor is
the reciprocating compressor. It
comes into two domes or
housing:
1. Open compressors
2. Hermetic compressors
Hermetic compressor is the most
common air conditioner
compressors found in residential
AC units and light commercial
units. So, the only compressor I’ll
being focusing here is hermetic
compressors.
Hermetic compressor comes into
two types:
1. Sealed or welded hermetic
compressors
2. Semi-hermetic (this compressor
has nuts and bolts holding it
together.)
Sealed hermetic compressors
Welded hermetic compressors
aka tin can or sealed hermetic
are throwaway compressors.
There is no way of get inside the
compressor, unless it ’s cut open.
There’re few companies that
open this compressor, they are
specialize this kind of works. Air
conditioner compressors
manufacture opens the sealed
hermetic compressors to
examine it. Otherwise, its a
throwaway.
In sealed hermetic compressors
the motor and crankshaft are in
vertical position. It used the
suction refrigeration from the air
conditioner evaporator to cool
the internal compressor at an
operating temperature.
The air conditioner compressors
have a safety device inside to
protect the compressor from
heating. This device is internal
overload. The air conditioning
compressor is the most
expensive AC parts in condenser
units; it ’s wise to protect the
compressor.
In a hermetic compressors
there ’re two important tubes
that welded with the hermetic
shell. These two tubes are:
1. Suction line
2. Discharge line
The suction line is the larger line
connecting to the indoor air
conditioner evaporator. The air
conditioner compressors pull the
refrigerant through the suction
line and releases it to the air
conditioner condenser through
the discharge line.
In split-central air conditioner
units, the suction is always
insulating to prevent the cool
refrigerant from absorbing
outside heat.
Semi-hermetic compressors
This is the air conditioning
compressors that have nuts and
bolts. The motor and the
compressor are inside the heavy
iron cast. This is the compressor
that can be fixed by removing
the bolts and shells that holding
it together.
There aren’t many residential
that used these types of
compressor, but you could find
in larger home and light
commercial. It can be fixed in the
field, if you have the necessary
air conditioner equipment.

How does a central air
conditioner compressor works?
The central air conditioner
compressor works by using an
electricity to energize the motor;
which it turns cause compressor
crankshaft to rotates.
Reciprocating compressors are a
piston-cylinder type of pump.
The main parts include a
cylinder, piston, connecting rod,
crankshaft, cylinder head and
valves. The operating cycle of a
reciprocating compressor is
shown below.
On the down stroke of the
piston, a low pressure area is
created between the top of the
piston, the cylinder head and the
suction line of the air
conditioning evaporator. Cold
refrigerant vapor rushes
through the suction valve inlet
and into the low pressure area.
On the up stroke, the suction
valve closes and the exhaust
(discharge) valve is forced open
with the increasing pressure. The
vapor is compressed and forced
into the discharge (high) side of
the refrigeration system.
When the piston reaches the top
of the cylinder, the discharge
valve closes, and the suction
valve opens as the piston starts
down again drawing in cold
refrigerant vapor to complete
the cycle.
Note that the connecting rod
attached between the crankshaft
and piston serves to change
rotary motion into reciprocating
(back and forth) motion.
The piston rings prevent the
vapor from escaping between
the piston and cylinder walls and
improve the operating
efficiency.
The compressor housing or
crankcase contains the bearing
surfaces for the crankshaft and
stores the oil that lubricates the
compressor parts.
The process of the air
conditioning compressors are
showed between points 1 and 2
on the PH chart.
In split- central air conditioner
units, the compressor is located
outside within the condenser
units. It ’s a vapor pump!
Compressors produce a pressure
different between the low side
(suction pressure) and high sides
(discharge pressure) of the
refrigeration system.
This is achieved by pulling of
low pressure, low temperature,
superheated refrigerant vapor
from the suction (evaporator)
side.
It pulls the correct amount of
refrigerant to fill the volume. The
refrigerant goes through the
compressor, after it crosses the
compressor it then creates a
high temperature, high pressure
superheated refrigerant vapor to
the high pressure side (air
conditioner condenser side).
The compression of the vapor
causes the transfer of heat
energy to flows from the low
side to the high side of the
system.
As the air conditioning
compressors compression the
refrigerant, additional heat is
added to the refrigerant. These
heats are:
1. Heat of compression
2. Mechanical friction heat
3. Compressors winding heat
4. Other suction line heat
The pressure different created
by the operation of the
compressor is responsible for
refrigerant flow through the
refrigeration cycle.

Re: (solve) No Frost, hindi lumalamig ang ibaba, ang itaas ay na

Problem:
No Frost refrigerator - hindi lumalamig ang ibaba, sa itaas ay nag yeyelo.

1. Check ang fan sa loob, (umaandar naman, good pa)
2. Check ang heater ( iniikot ang timer para maset ang heater, ok naman, umiinit, good pa)

3. Check ang defrost timer (pinanghinalaan na ito dahil madalas itöng masira kapag pinapasok ng langgam, pinalitan ng bagong timer, after ng isang linggo, ganun pa din, nagyeyelo sa itaas, at sa ibaba ay di lumalamig)

4. Check ulit ang itaas, binaklas. Tinunaw muna ang yelo sa evaporator para ma check, napansin ko di ko malaman kung saan dumadaan ang natunaw na tubig ng yelo. Barado pala ang drain plug, natiyak ko yun dahil walang lumalabas na tubig sa likod ng refrigerator. May sarahuran ng tubig dun walang lumalabas na tubig na natunaw na yelo sa itaas. Ang ginawa ko, sinundot ko ng kawad ang drain hose, mula sa likod ng ref. sa ilalim pataas sa evaporator. Medyo mahirap, at matigas ang pagsundot at ingat na din na matamaan ng tubo (hayun ok na ang ref. Maganda na ang lamig)[/quote]

Basic refrigeration, my tutorial

How to know the STARTING, COMMON and RUNNING terminal of the compressor motor

gagamit tayo ng tester na naka setting sa ohms or resistance.
RS =highest reading
CS
=medium reading
CR
=lowest reading
sa larawan nilagyan natin ng number 1,2,3
1-2 = 3 ohm CR
1-3 = 7 ohm RS
2-3 = 5 ohm CS
madali lang naman malaman kung alin dito common, starting at running.
Ang 1-2 ay CR kaya lowest reading ito ay walang 3 kaya ito ay para sa terminal 3, ito ay CR, at sa CSR, wala itong S, kaya starting ito
Ang 1-3 ay RS Highest Reading, terminal 2, at C Common, yun ang wala sa kanya.
Ang 2-3 ay CS medium reading, kaya terminal 1, at running
sagot:
3 = S
2 = C
1 = R
another example:
1-2 = 3 ohm CR 3 = S
1-3 = 5 ohm CS 2 = R
2-3 = 7 ohm RS 1 = C
madali ding mag test kahit hindi ka na magsulat. Kapag ang tester halimbawa ay itinutok mo sa terminal 1 at 3 kung yun ang mataas ang 1-3 ang katapat nun na 2 ang sinusukat mo kaya ang 2 ang common. Kung 2-1 ay lowest ang katapat n 3 ang sinusukat mo at ang 3 ang starting.

Refrigeration =process of removing heat from a close space.
1. Compressor motor =use to compress low pressure, low temp. to high pressure, high temp. refrigerant required by the system.
2. Discharge Line =passage of compress hot gas refrigerant.
3. Condenser or Condensing coil =use to give-off heat, transfer of heat to the cooling medium or atmospheric temperature.
4.Filter/Drier
A. Filter =use to screen dirt, sludge, scale and foriegn matter.
B. Drier =use to absorve moisture circulating to the system.
5. Capillary Tube =use to regulate, control the flow of refrigerant (ang tawag ng iba dito ay expansion valve at mahalaga ito para magkaroon ng evaporation)
6. Evaporator Coil or Cooling coil =use to absorb heat inside close space.
7. Accumulator Tube =use to hold the remaining liquid refrigerant. (dito maipon ang liquid refrigerant na hindi naging gas or nag evaporate, para di pumunta ang liquid sa compressor na dahilan kung bakit masisira, malulunod ng liquid ang compressor, ang trabaho nya ay mag pump lang ng gas.)
8. Suction Line =passage of vapor refrigerant.
Vapor =low pressure,low temperature gas
Freezing Temperature of water = 0 centigrate or 32 farenheight
Melting point of water =1 centigrate to 20 centigrate in 3 hour.

Central air conditioner compressors

What are air conditioner
compressors?
Air conditioning compressor is
the heart of the air conditioner
units. It’s the mechanical
components that use electricity
and capacitor as the single
energy source to operate it.
The air conditioning compressor
is the ac parts that cause the air
conditioner refrigerant to flows
in a cycle.
What are the types of air
conditioning compressors?
There are five main types of air
conditioner compressors:
1. Reciprocating
2. Rotary compressor
3. Centrifugal compressor
4. screw compressors
5. Scroll compressors
All five groups of air conditioner
compressors work the same
way, but their internal methods
of compressing refrigerant
vapors are different.
The most common compressor is
the reciprocating compressor. It
comes into two domes or
housing:
1. Open compressors
2. Hermetic compressors
Hermetic compressor is the most
common air conditioner
compressors found in residential
AC units and light commercial
units. So, the only compressor I’ll
being focusing here is hermetic
compressors.
Hermetic compressor comes into
two types:
1. Sealed or welded hermetic
compressors
2. Semi-hermetic (this compressor
has nuts and bolts holding it
together.)
Sealed hermetic compressors
Welded hermetic compressors
aka tin can or sealed hermetic
are throwaway compressors.
There is no way of get inside the
compressor, unless it ’s cut open.
There’re few companies that
open this compressor, they are
specialize this kind of works. Air
conditioner compressors
manufacture opens the sealed
hermetic compressors to
examine it. Otherwise, its a
throwaway.
In sealed hermetic compressors
the motor and crankshaft are in
vertical position. It used the
suction refrigeration from the air
conditioner evaporator to cool
the internal compressor at an
operating temperature.
The air conditioner compressors
have a safety device inside to
protect the compressor from
heating. This device is internal
overload. The air conditioning
compressor is the most
expensive AC parts in condenser
units; it ’s wise to protect the
compressor.
In a hermetic compressors
there ’re two important tubes
that welded with the hermetic
shell. These two tubes are:
1. Suction line
2. Discharge line
The suction line is the larger line
connecting to the indoor air
conditioner evaporator. The air
conditioner compressors pull the
refrigerant through the suction
line and releases it to the air
conditioner condenser through
the discharge line.
In split-central air conditioner
units, the suction is always
insulating to prevent the cool
refrigerant from absorbing
outside heat.
Semi-hermetic compressors
This is the air conditioning
compressors that have nuts and
bolts. The motor and the
compressor are inside the heavy
iron cast. This is the compressor
that can be fixed by removing
the bolts and shells that holding
it together.
There aren’t many residential
that used these types of
compressor, but you could find
in larger home and light
commercial. It can be fixed in the
field, if you have the necessary
air conditioner equipment.

How does a central air
conditioner compressor works?
The central air conditioner
compressor works by using an
electricity to energize the motor;
which it turns cause compressor
crankshaft to rotates.
Reciprocating compressors are a
piston-cylinder type of pump.
The main parts include a
cylinder, piston, connecting rod,
crankshaft, cylinder head and
valves. The operating cycle of a
reciprocating compressor is
shown below.
On the down stroke of the
piston, a low pressure area is
created between the top of the
piston, the cylinder head and the
suction line of the air
conditioning evaporator. Cold
refrigerant vapor rushes
through the suction valve inlet
and into the low pressure area.
On the up stroke, the suction
valve closes and the exhaust
(discharge) valve is forced open
with the increasing pressure. The
vapor is compressed and forced
into the discharge (high) side of
the refrigeration system.
When the piston reaches the top
of the cylinder, the discharge
valve closes, and the suction
valve opens as the piston starts
down again drawing in cold
refrigerant vapor to complete
the cycle.
Note that the connecting rod
attached between the crankshaft
and piston serves to change
rotary motion into reciprocating
(back and forth) motion.
The piston rings prevent the
vapor from escaping between
the piston and cylinder walls and
improve the operating
efficiency.
The compressor housing or
crankcase contains the bearing
surfaces for the crankshaft and
stores the oil that lubricates the
compressor parts.
The process of the air
conditioning compressors are
showed between points 1 and 2
on the PH chart.
In split- central air conditioner
units, the compressor is located
outside within the condenser
units. It ’s a vapor pump!
Compressors produce a pressure
different between the low side
(suction pressure) and high sides
(discharge pressure) of the
refrigeration system.
This is achieved by pulling of
low pressure, low temperature,
superheated refrigerant vapor
from the suction (evaporator)
side.
It pulls the correct amount of
refrigerant to fill the volume. The
refrigerant goes through the
compressor, after it crosses the
compressor it then creates a
high temperature, high pressure
superheated refrigerant vapor to
the high pressure side (air
conditioner condenser side).
The compression of the vapor
causes the transfer of heat
energy to flows from the low
side to the high side of the
system.
As the air conditioning
compressors compression the
refrigerant, additional heat is
added to the refrigerant. These
heats are:
1. Heat of compression
2. Mechanical friction heat
3. Compressors winding heat
4. Other suction line heat
The pressure different created
by the operation of the
compressor is responsible for
refrigerant flow through the
refrigeration cycle.
