[ Five ] Types of Air Conditioner Compressor Structure

We have to know about Air conditioner’s cycle before knowing the types of ac compressor. Inside each cooling unit is a blower. The blower assumes the imperative job of compacting the refrigerant as it enters the machine so as to expand its temperature.

When warmed, the gas leaves the blower and goes into the condenser so the cooling procedure can start. While all AC blowers have similar activity, they work in shifting ways and offer diverse advantages and disadvantages.  We are showing you about the types of air conditioner compressor.

Types of Air Conditioner Compressor

The responding blower is the most well-known sort of AC blower. A cylinder packs the air by climbing and down within a chamber. As the cylinder moves down, it makes a vacuum impact that sucks in the refrigerant. As it climbs, the gas packs and moves into the condenser. A responding cooling blower is exceptionally productive, as AC units can have up to eight chambers inside the blower.

1. Scroll AC Compressor 

types of air conditioner compressorParchment cooling blowers, similar to this LG blower, are more up to date on the scene. They contain one settled loop—called the look—in the focal point of the unit, and after that, there is another curl that turns around it. Amid this procedure, the second parchment pushes the refrigerant towards the middle and packs it.




2. Screw AC Compressor 

types of air conditioner compressorThe screw blower is very solid and proficient, yet it’s for the most part utilized in extensive structures where there is a tremendous measure of air that requires persistent cooling. A screw cooling blower contains two expansive helical rotors that move the air from one end to the next. Cold travels through the blower. This reduces the space, and it packs.




3. Rotary Air Conditioning Compressor 

types of air conditioner compressorRevolving blowers are little and calm, so they are well known in areas where clamor is a worry. Within this sort of AC blower contains a pole with a few cutting edges connected to it. The bladed shaft turns inside the graduated barrel, therefore pushing the refrigerant through the chamber and compacting it at the same time.


4. Reciprocating Compressor 

types of air conditioner compressorThe use of Reciprocating Compressor in a window and split air conditioner. Reciprocating Air Conditioner Compressor has more power comparing to the rotary compressor. after reaching 50 degrees temperature, Reciprocating Air Conditioner Compressor will not stop working. and the rotary compressor tripping after 50-degree temperature.
Wind up and down inside a cylinder. As the piston goes down, it creates a vacuum effect that becomes useless in the cold. As it grows up, the gas shrinks and goes into the condenser. A reciprocating air conditioning compressor is very efficient because AC units can have up to eight cylinders within the compressor.


5. Centrifugal Air Conditioning Compressor 

types of air conditioner compressorThe last kind of AC blower is the outward blower. As the name infers, it utilizes radial power to pull in the refrigerant gas and after that turns it quickly with an impeller to pack it.

AC not blowing cold air

Top Reasons Why AC Not Blowing Cold Air

With the rise in temperature every summer, air conditioning systems are no more a luxury. Instead, they have become the one-stop solution to beat the scoring heat of the sun and enjoy a comfortable stay indoors. Today, they have become a must-have device in every home as well as a commercial organization. With the aid of these products, you will be capable of sleeping properly in a pleasant environment. Nothing can make your day worse than a malfunctioning AC during the summer. At times, you might find that the device is working completely and yet AC not blowing cold air. 

After thorough research in the World Wide Web, we have come to the verdict that a wide array of users encounters such issues during the summer. There are a bunch of reasons why AC not blowing cold air. Take a look below to know more!!!



The Clogging of Air Filters – AC Not Blowing Cold Air

Your Air conditioning system might fail to blow cold air if you have not change the air filters for quite a while. The dirt, dust, particles and the contaminants, get accumulated in these air filters. It results in an interruption in the flow of air. Thus, the coils will be freezing over. It will lead to a wide assortment of issues such as blowing hot air, higher utility bills, a puddle. To overcome such an issue, you should change the air filters once every month.


Incorrect Setting of The Thermostat

The wrong setting of the thermostat plays an indispensable role in the blowing of cold air by the AC. In case you set the thermostat to a higher threshold, there are chances that it has not been turning on.

For instance, say the temperature is 24 degrees C. Yet, you have set the AC to 27 degrees C. So, you may not feel the cold air. The AC might also not cool in case it is set in the Auto setting, in place of ‘On’. Hence, you need to do your bit of research.

In the beginning, you should take a look at whether the shut-off switch is flipped or not. You also require checking the breakers and ensure that nothing is tripped off. Next to that, you should make sure to reset the thermostat. After this, the temperature will get reduced to a few degrees than before.

If the temperature in your home is 25 degrees C, you should set it to 20 degrees C. You will find certain changes in this way. After waiting for some time, check out the vents and see whether you can feel cold air. There are high chances that you can get rid of the issue by a simple reset.

Dirty Evaporators

If you are an owner of the air conditioning system, you might be aware of the fact that the evaporator contributes to being an integral part of the aircon. This integral part of the AC system assures the proper functioning of the device. It also plays an integral role in making your home cool. 

You need to keep in mind that the aircon will fail to confer an effective functioning in the absence of the clean evaporator, resulting in utmost discomfort during hot summer. Hence, it is a prerequisite to check out the evaporator after certain regular intervals to avoid any sort of hassles later on. 

Besides this, you should ensure to maintain the proper functioning of it regularly. As a regular user of the air conditioning system, you should make sure to clean the aircon after the regular intervals of 6 months to a year.



The Size of The Air Conditioner

You might find that the air conditioning system is not blowing sufficient cold air if you buy an air conditioner of smaller size for homes of large size. You should make sure to opt for an AC which is capable of cooling the whole of your space. In case you have a home of small size, you should make sure to pick compact models. Similarly, if you have a larger home, go for air conditioning systems of large size.

 There is no point in selecting a compact model for larger rooms as it might disrupt the performance capacity of the AC’s aircon owing to which it will not be capable of working properly. Likewise, the larger models are not ideal for compact rooms as it will cool the room excessively and there are chances that you will fall ill.



Damaged Compressor


A compressor happens to be an integral component of the air conditioning unit. It can maintain the refrigerant’s flow between the condenser and the evaporator. Hence, if this specific part of the AC system gets damaged, it will not be successful in imparting cool air. It is better to replace the damaged compressor in such cases.


Dirty Condenser

You need to check out whether the condenser, present in the outdoor unit is dirty or not. If you find that the condenser, within the outdoor unit has become dirty, you should wash it. If dust or dirt reaches in the condenser of the outdoor unit, it will take an excessive load in the ventilation of the air. As a result, the condenser will become overheated time and again.

Next to this, the compressor will be tripping more within no time. As a result, the air conditioning system will not be capable of conferring cold air. Hence, you should make sure that the condenser within the outdoor unit is clean. Hence, you need to clean the condenser with the aid of the water pressure.



Leakage in The Refrigerant

The refrigerant cycles are known to run within the air conditioner. The leakage in the refrigerant of the air conditioning system contributes to being a crucial reason why the device does not blow the cold air. 

You should refrain from using the AC if you are encountering a refrigerant leakage issue. If you hear any hissing noise, once the air conditioner starts, there are risks of leakage within the refrigerant. The problem can also be identified if the system seems to be frozen.



If The Blower Gets Blocked

If you fail to clean the air conditioner’s filter, it might result in the gradual collection of dust in the blower owing to which the blower will fail to throw cool air. It is recognized to be another vital reason why the air conditioning system fails to confer cold air. Besides this, there are risks that the fan motor, present in the indoor unit might be damaged.

 In case you feel that the air conditioner motor is not functioning, you can be ensured that the air conditioning system will not be blowing cold air. Apart from this, the speed of the AC motor will be slower. As the capacitor, present in the fan motor of the air conditioning system gets weak; it will be reducing the speed of the blower. The AC will fail to blow cold air in such circumstances as well.



Leakage in The Air Ducts

Air traverses via a series of air ducts before it reaches the rooms in the home. With time, air ducts will be sealed, as a result of which they will be losing the insulation. It causes leakage in the air. Owing to this, too much cool air will get escaped and the rooms will not get enough cool air.

As the cool air will escape, it will be challenging for the home for reaching the desired temperature. If the air ducts of the AC have become older, you need to schedule the inspection.



Faulty PCB and programming issues

Three-minute technical programming is present within the air conditioner. Once you turn the AC on, you need to wait for this duration in which electricity gets supplied to the outdoor unit. You need to wait until the compressor of the air conditioning system starts. If you try to change the mode of the AC with the remote control, you will find that the compressor is not operational.

In such circumstances, you might find yourself in extreme warm temperature. It is because the cold air will not be blowing, with the starting of the air conditioner. At times, PCB fails to supply electricity to the specific outdoor unit. Thus, the AC might not be successful in blowing cold air.

To ensure that your air conditioning system is working, you need to service and maintain them. Hence, you need to service it every three months for increasing the output and efficiency of the AC units.

Outside AC Unit Not Turning On | [ 6 Common Problems ]

This is a big thing when the summer has comes and your air conditioner will not work. Now you don’t have to wait for coming an ac professional to help. It is not difficult to identify and repair many air-conditioning malfunctions.
The following testing process will help you to identify why outside ac unit not turning on. You can identify the problem of your outer unit is from the fan motor, Capacitor or Contactor. 
Here is some way to identify and fix your outside ac unit not turning on:

1. Temperature Control or Thermostat Problem 

If your air conditioner coil is upwards, then there may be a problem with temperature control or thermostat. This part monitors the air temperature of the room. If necessary, indicates the compressor to be started to start the cooling. 
Outside AC Unit Not Turning On | [ 6 Common Problems ]
There is a most common reason for outside ac unit not turning on. If we have a 30°C temperature sets in our air conditioner display and, our room’s temperature is below 30°C, then our outer unit will not be operational.

Always set the temperature of your air conditioner below from the temperature of the room. Then our thermostat will supply energy to the outer unit.
AC Not Blowing Cold Air| [ 10 Reasons ]
The temperature control will have a sensor bulb. The sensor bulb is located near the evaporative coil. It helps to monitor the temperature of the air. If the temperature control is not working properly, then it can expect a compressor to last longer and cool down the room below the ideal temperature.

At this point, the evaporator cannot take heat from the room that takes coils on ice. This is especially common during the period of intense humidity. Check sensor bulbs for signs of damage such as crack or bent, and the correct placement within the evaporator coil system.

2. Electronic Control Board Problem 

Outside AC Unit Not Turning On | [ 6 Common Problems ]If your outside ac unit not turning on and you have confirmed that the power source is good, then the problem may be the electronic control board. This portion is used almost all air conditioner units to help control various parts. An indication that the control board is not working, is not running the fan or compressor circuit.

Check the control board for a blown fuse. First to consult your user manual to make sure that your control board has an internal fuse. Replace your control board with the same specifications. Your problem of not starting an outer unit will fix. 

3. Contactor Problem

Is your outside ac unit not turning on? let’s check the contactor. Our air conditioner’s outer unit has a contactor. In it, 220 volts pass. The contactor passes 220 volts to the motor and compressor from it. If our PCB is supplying the Outer Unit, then we should check the contactor in our outer.

The work of the Contactor is to control the voltage. We need to check it by the multimeter.  If the Contactor gets worse, then it will not be able to throughout the voltage to fan motor and compressor. You cant repair it at home. To fix this issue, you need to change the contactor as the same specification. Your Air conditioner will work smoothly.

4. Weak or Open Starting capacitor

The most likely reason for your outside ac unit not turning on is due to a faulty Starting capacitor. If the Capacitor will be weak or open, the outside ac unit will not turn on. The reason for the weak or faulty capacitors will be the voltage fluctuation.

If there is a voltage problem in the house, your ac compressor won’t work smoothly. A low level of voltage will affect the compressor load and the capacitor will be weak or open.

To inspect a capacitor, remove the cabinet cover. Check it by the MFD meter or the signs of damage, and replace the capacitor when damaged. Make sure the specification must be the same as your air conditioner unit required.

5. Fan Motor Or Fan Blade Problem

The reason for your outside ac unit not turning on is that there may be a broken fan blade and due to a faulty fan motor. Fan capacitor is also a reason for the faulty motor. Check The capacitor for weak or damaged.

If the fan is moving slowly or not running at all, the compressor is not working enough and there is a danger for compressor health. Call the professionals immediately.

To reach the fan and fan motor, unplug the unit and remove the cabinet cover.  Try turning the motor manually To see it rotates smoothly. check the fan blade for the loose-fitting or broken. If everything looks normal, then the Fan motor may be faulty. it will need to be tested by a qualified technician.


6. Low level of Refrigerant in Yor Air Conditioner

Outside AC Unit Not Turning On | [ 6 Common Problems ]The air conditioner’s internal gas is necessary for the cooling process. because it absorbs heat from the inside of the room and thus leads to poor cooling. The only reason behind low levels of refrigerant is the presence of leakage somewhere. This is one of the reasons for your outside ac unit not turning on.

If there is a low level of refrigerant, PCB will sense it and will never throughout the supply to the outside unit. Iside PCB will show an error in the display, like” E6, or according to your air conditioner brand. Do not try to fix this issue at home. You can hire an ac professional In this situation.
