What are the Different Components of an Air Conditioner Unit?While there are several different types of air conditioning equipment, In the most basic air conditioning system, you will realize they all share the same essential components. 

 

Whether you have an air conditioning unit in your home or your car, it consists of 3 main parts: the condenser, the compressor, and the evaporator.

In Summary, The compressor is the heart of an HVAC system and it is responsible for pumping out cold refrigerant gas that will eventually be cooled and heated to serve the purpose of cooling or heating a space.

The evaporator is the heat-exchanging component of the system and is responsible for cooling or heating airflow to and from the space. Finally, the condenser is responsible for cooling the refrigerant gas before it returns to the compressor to be used again. other parts include the Refrigerant and the Thermostat

This post will discuss the differences between these components and how they relate to the overall operation of your air conditioner.

      1. Refrigerant

Refrigerant is a substance used in air conditioning units that helps to make your home or office more comfortable. It is an integral part of an air conditioning unit and is used primarily for cooling and dehumidifying the air. 

Refrigerants are typically colorless, odorless, highly flammable gas and is the reason that it is stored in a refrigerant container.

Just as your car wouldn’t run without gas, your air conditioner won’t run without refrigerant. The refrigerant is the lifeblood of your AC, carrying out three critical functions: it absorbs heat and cools your home; it carries the heat away from your home through the outside condenser coil, It helps regulate the air pressure in the system. 

The refrigerant is put into an air conditioner to help maintain the most efficient temperature possible, but it is also used in other HVAC units like heat pumps.

What are the two types of refrigerants? 

There are many kinds of coolant and several different kinds of refrigerant, but they are similar in some ways. While the exact chemical makeup of refrigerant varies depending on the type of system you have, It is usually a mixture of gases in a low-temperature liquid phase, such as propane, butane, isobutane, R-410A.

There are two main types of refrigerants we have: the hydrofluorocarbons (HFCs) used in most AC units today and the chlorofluorocarbons (CFCs) used in the past.

      2. Compressor

Air conditioners can be complex pieces of equipment. Still, the basic principle behind them is relatively straightforward. Air conditioners release heat in one of two ways: through the evaporation of a liquid or by compressing and expanding a gas like Freon or R-410A.

The process for cooling the interior of a home or business, either through evaporation or compression, is essentially the same in all air conditioners. Still, the method of reaching the desired temperature is very different.

The compressor is the heart of the air conditioning and heating system. It is located inside the air conditioning unit or furnace and is what makes the unit work. It is a sort of pump that is used to pump refrigerants.

What are the three most common types of compressors used in air-conditioning

The compressors compress the refrigerant gas to a liquid and pump it under pressure to the other air conditioner components. The three most common types are scroll, reciprocating, and screw compressors. Scroll compressors are by far the most popular in central air conditioners since they are the quietest and lightest of the three.

      3. Condenser Coil

A condenser coil, also known as a heat-recovery coil, is a vital part of any air conditioning system when working correctly. It’s also one of the most misunderstood components. Generally, the condenser is a coil that is used to transfer heat from the outside air to the refrigerant, which is the substance that helps transfer heat from your home to the outside air.

The Condenser is responsible for cooling the refrigerant, which can cool the air in your home. Each system is different, but generally, air flows through the coil, submerged in a liquid refrigerant, picking up the cool air and expelling the hot air. 

When your system doesn’t seem to be working, sometimes the problem is the condenser coil. Inspecting it and cleaning it can help your system run more efficiently.

What happens when the AC condenser goes bad?

If your air conditioner’s condenser is bad, it can cause all kinds of problems. The condenser is the part of the outdoor units that cool the refrigerant. If the condenser leaks, it can cause an increase in the pressure in the system, which will cause the compressor to run constantly in an attempt to keep the pressure at a safe level.

If the pressure gets too high, the refrigerant could come out of the compressor in the form of a liquid and then to a gas, which will cause the system to freeze up. This requires repair services immediately because if the liquid refrigerant freezes, it can damage the compressor.

      4. Evaporator Coil

Have you ever looked at a split air conditioner and wondered what all those parts do? If so, we can help. The evaporator is a heat transfer device that changes liquid refrigerant into a gas. This heat is absorbed by the refrigerant and passed to the condenser. The condenser then uses it to heat the refrigerant. The heat is rejected by the condenser and sent outside to the condenser.

Evaporator coils are the lifeblood of an air conditioner, and it’s important to keep them clean. They are usually located right under the front grill of your air conditioner, in the cold air return. It is usually fed air from an air handler or furnace.

They are responsible for cooling the air, which is then blown out into the house’s air ducts. The evaporator coil is the part of the air conditioning system that changes the air temperature.

How do I know if my AC evaporator is bad?

Your air conditioner evaporator is the component of your air conditioner that cools the air. If your air conditioner evaporator is bad, your air conditioner will not work properly. And it is important to sense that your air conditioner evaporator is bad so that you can get it repaired before it causes major problems.

The best way to know if your air conditioner evaporator is bad is to have an AC repair professional look at your air conditioner unit.

      5. Thermostat 

The thermostat is the device that controls the temperature in your home, so naturally, you have a lot of questions about how thermostats do what they do.

A thermostat is an electronic device found in air conditioners or heat pumps that regulate the flow of refrigerant to the compressor to maintain the temperature of the air (or liquid/fluid) being blown through the evaporator.

The thermostat monitors the temperature of this air (or liquid/fluid) and turns the compressor on and off as needed to maintain the desired room temperature. The thermostat is usually set on a wall by the air conditioner and has various settings that can be adjusted depending on the desired temperature and Programmable thermostats make it even easier.
