What is an Air Conditioning Condenser?

An air conditioning condenser is a vital part of an air conditioner responsible for cooling vapors coming from a compressor. It is not only used in traditional air conditioners, but also refrigerators and almost any other type of device that delivers refrigerant, or cooled air, to another location. Sometimes, this portion of the air conditioner is confused with the outside unit in a split system.

The air conditioning condenser looks very much like a coil, or perhaps a radiator. Its job is to take hot gaseous vapor coming from the condenser, and cool it back into a liquid form. It does this through a process called condensation. Water vapor in the air, which is a gas, goes through a similar process when it becomes liquid dew, commonly seen in the morning. The condenser cools the gas to a certain point to create the same effect.

Heat in an air conditioning condenser is transferred through the coils, and then out into the air. In an air conditioning unit the hot air is expelled outside, and the liquid refrigerant then moves on to the next step in the process, which is the expansion device. In the case of refrigerators, the hot air is usually simply expelled underneath or behind the unit. In most cases, the condenser will need a little help to cool the liquid fast enough, which is why a fan is often used. The fan does not truly make the refrigerant cooler, but rather aids in the transfer of heat from inside the coil to the surrounding air. Thus, the natural result is less heat in the refrigerant itself.

It should be noted that while many outside units are referred to as air conditioning condensers, that is not the truth. The most visible part of the units in the outside shell is often the condenser unit or components that help the condenser, which may be why there is some confusion. The condenser is actually one of multiple components located inside that shell. Also included in the outside portion of a split air conditioning system is the compressor. The components work together to provide the desired cooled air to a controlled environment.

Depending on the age of the air conditioner, its running conditions and use, there may be certain parts of the air conditioning condenser that need to be replaced from time to time. These include the coils, commonly called evaporator coils, which may become corroded eventually. This could cause refrigerant to leak out. The fan motor is another unit vital to the condenser that may go bad from time to time.

Air conditioning Btu for Homeowners

Air Conditioning Btu – Measure how much heat energy air conditioner unit produce.

An air conditioner manufacture needs away to compare the amount of heat is produce on specific period and need to know how much heat is remove on specific period (day, hour, minute).

What is air conditioning Btu?

Btu is a British thermal unit. It’s a unit of heat energy. Btu defines as the amount (quantity) of heat needed to raise the temperature of 1 pound of water to 1 degree F.

For example: when 5 lb of water is heated from 10°F to 20°F. 50 Btu of heat energy is added to the water. To look at in a different way, the water now contains 50 Btu of heat energy.

Here is the Btu’s formula:

Btu = Wt in lb. x change in temperature in °F

Btu = 5 lb X (10-20)

Btu = 5 x 10

Btu = 50 Btu

HVAC technician used the terms Btu to describe the quantity of heat or heat content. Btu explains the amount of heat energy contains in a substance. In the example above, the water contains 50 Btu.

Let’s said a furnace has 15000 Btu. It means that the furnace wills produce 15,000 Btu of heat within specific period.

When it comes to air conditioner, it entirely difference. 15,000 Btu air conditioners mean that the air conditioner unit will remove 15,000 Btu of heat energy from a resident.

Each components of heating or air conditioner unit is rated base on their ability to remove heat or add heat. If the hvac equipment is not rated, it would be hard to choose the best air conditioner unit or heating unit.

Ton of Refrigeration or Ton of Air Conditioner.

Air conditioning Btu is a unit use to measure quantity of heat energy and ton of refrigeration is a measurement unit use to size air conditioner unit or refrigeration units.

The terms ton of refrigeration goes back went they used ice as the source to remove heat. It requires 144 Btu of heat energy to melt one pound of ice at 32°F to one pound of water at 32°F.

Ton of refrigeration refers to the amount of heat needed to melt 1 ton of ice in a day (24 hours). 1 ton of refrigeration is equal to 2000 pound of refrigeration (1 ton = 2000 lb). Here how to converts ton of refrigeration to Btu:

2000 lb x 144 Btu/lb = 288,000 Btu

288, 000 Btu is how much heat removes within 24 hours. In one hours, the air conditioner unit removes 12, 000 Btu of heat (288, 000 Btu/ 24 = 12, 000 Btu) or in minute, it would be 200 Btu /min.

Here is different prospective. 1 Ton of air conditioner unit will remove 12, 000 Btu of heat per hours.

Main Components of an Air Conditioner.

Let's get some housekeeping topics out of the way before we tackle the unique components that make up a standard air conditioner. The biggest job an air conditioner has to do is to cool the indoor air. That's not all it does, though. Air conditioners monitor and regulate the air temperature via a thermostat. They also have an onboard filter that removes airborne particulates from the circulating air. Air conditioners function as dehumidifiers. Because temperature is a key component of relative humidity, reducing the temperature of a volume of humid air causes it to release a portion of its moisture. That's why there are drains and moisture-collecting pans near or attached to air conditioners, and why air conditioners discharge water when they operate on humid days.

Still, the major parts of an air conditioner manage refrigerant and move air in two directions: indoors and outside:

Evaporator - Receives the liquid refrigerant

Condenser - Facilitates heat transfer

Expansion valve - regulates refrigerant flow into the evaporator

Compressor - A pump that pressurizes refrigerant

Compressor

Compresses the refrigerant from low pressure (low temperature) to high pressure (high temperature). This conversion raises the boiling point to higher temperature levels, facilitating elimination of the heat brought by the outdoor air.

Condenser

This component receives gas at high pressure and high temperature from the compressor. In air-cooled condensers, the metallic surfaces cool the gas which changes status and turns to liquid. In the case of water-cooled condensers, it is the circulation of the water that produces the same cooling effect.

Evaporator

When the refrigerant evaporates in the evaporator, it absorbs heat from the surrounding air and produces cooled air.

The cold side of an air conditioner contains the evaporator and a fan that blows air over the chilled coils and into the room. The hot side contains the compressor, condenser and another fan to vent hot air coming off the compressed refrigerant to the outdoors. In between the two sets of coils, there's an expansion valve. It regulates the amount of compressed liquid refrigerant moving into the evaporator. Once in the evaporator, the refrigerant experiences a pressure drop, expands and changes back into a gas. The compressor is actually a large electric pump that pressurizes the refrigerant gas as part of the process of turning it back into a liquid. There are some additional sensors, timers and valves, but the evaporator, compressor, condenser and expansion valve are the main components of an air conditioner.

Although this is a conventional setup for an air conditioner, there are a couple of variations you should know about. Window air conditioners have all these components mounted into a relatively small metal box that installs into a window opening. The hot air vents from the back of the unit, while the condenser coils and a fan cool and re-circulate indoor air. Bigger air conditioners work a little differently: Central air conditioners share a control thermostat with a home's heating system, and the compressor and condenser, the hot side of the unit, isn't even in the house. It's in a separate all-weather housing outdoors. In very large buildings, like hotels and hospitals, the exterior condensing unit is often mounted somewhere on the roof.

Air-Conditioning Basics.

The first modern air conditioning system was developed in 1902 by a young electrical engineer named Willis Haviland Carrier. It was designed to solve a humidity problem at the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, N.Y. Paper stock at the plant would sometimes absorb moisture from the warm summer air, making it difficult to apply the layered inking techniques of the time. Carrier treated the air inside the building by blowing it across chilled pipes. The air cooled as it passed across the cold pipes, and since cool air can't carry as much moisture as warm air, the process reduced the humidity in the plant and stabilized the moisture content of the paper. Reducing the humidity also had the side benefit of lowering the air temperature -- and a new technology was born.

Carrier realized he'd developed something with far-reaching potential, and it wasn't long before air-conditioning systems started popping up in theaters and stores, making the long, hot summer months much more comfortable.

The actual process air conditioners use to reduce the ambient air temperature in a room is based on a very simple scientific principle. The rest is achieved with the application of a few clever mechanical techniques. Actually, an air conditioner is very similar to another appliance in your home -- the refrigerator. Air conditioners don't have the exterior housing a refrigerator relies on to insulate its cold box. Instead, the walls in your home keep cold air in and hot air out.

How Air Conditioners Work?

Air conditioners use refrigeration to chill indoor air, taking advantage of a remarkable physical law: When a liquid converts to a gas (in a process called phase conversion), it absorbs heat. Air conditioners exploit this feature of phase conversion by forcing special chemical compounds to evaporate and condense over and over again in a closed system of coils.

The compounds involved are refrigerants that have properties enabling them to change at relatively low temperatures. Air conditioners also contain fans that move warm interior air over these cold, refrigerant-filled coils. In fact, central air conditioners have a whole system of ducts designed to funnel air to and from these serpentine, air-chilling coils.

When hot air flows over the cold, low-pressure evaporator coils, the refrigerant inside absorbs heat as it changes from a liquid to a gaseous state. To keep cooling efficiently, the air conditioner has to convert the refrigerant gas back to a liquid again. To do that, a compressor puts the gas under high pressure, a process that creates unwanted heat. All the extra heat created by compressing the gas is then evacuated to the outdoors with the help of a second set of coils called condenser coils, and a second fan. As the gas cools, it changes back to a liquid, and the process starts all over again. Think of it as an endless, elegant cycle: liquid refrigerant, phase conversion to a gas/ heat absorption, compression and phase transition back to a liquid again.

It's easy to see that there are two distinct things going on in an air conditioner. Refrigerant is chilling the indoor air, and the resulting gas is being continually compressed and cooled for conversion back to a liquid again. On the next page, we'll look at how the different parts of an air conditioner work to make all that possible.

Inverter in a Mini Split Air Conditioner.

Inverter Compressor.

Shopping for a mini split air conditioner got a little more difficult in the past couple of years. With the new federal regulations on minimum SEER ratings in the United States, manufacturers have started using inverter compressors to obtain 13 SEER or higher. This has created exceptional efficiency in wall mounted air conditioners, but also has increased the consumer cost.

The compressor is the heart and soul of every mini split air conditioner. It is the most essential component in an air conditioner and the most expensive. When purchasing a mini split air conditioner make sure to find a system with a solid warranty approximately 5 years in length. Also, make sure to purchase your mini split from a company that has parts available in the United States. Some companies can take up to three weeks to ship parts if they have to order them overseas.

I have read many articles talking about inverter compressors versus standard rotary compressors, but I think this sums it up best. A standard rotary or scroll compressor operates like a light switch: either on or off and nothing in between. An inverter compressor operates like a water faucet: it only uses enough power to reach the desired setting.

Benefits.

An inverter compressor is programmed to run at optimum speed, which is regulated by the input frequency as it varies between heat load requirements. Example: Your mini split is set at 72° F. The room becomes hot and the compressor needs to cool it by a couple of degrees. A standard compressor will turn “On” with full power, while an inverter compressor only uses enough resources (RPM) to reduce the room’s temperature to the desired setting.

Over a full day of operation, a standard compressor will have to turn on and off a substantial number of times. An inverter compressor will turn on and reach the desired setting and then idle at that setting until needed further.

By using different rotation speed, the inverter compressor is saving energy and operating more quietly than the standard compressor. Not having to constantly turn on and off at maximum RPM increases the lifespan of the inverter compressor.

When a large temperature change is needed, the inverter compressor can operate at a much higher RPM speed than the standard compressor, reducing the amount of run time and reducing your energy costs. Some researchers show a reduced power consumption as much as 60% versus a fixed speed standard compressor.

Inverter compressors offer a more precise temperature control for your mini split air conditioner. I hope this helps you understand how an inverter compressor operates and will help you make a decision with your ductless air conditioner purchase.

Ductless Air Conditioner vs Window Unit.

While looking for a way to cool one or two rooms, it's natural to consider a window air conditioner. For decades, window air conditioners have been the solution of choice under such circumstances. They're cheap, relatively easy to install and effective. Lately, however, ductless air conditioners, which are also known as mini split systems, have been giving window units a run for their money. Some people still sometimes rule them out due to the fact that they're more expensive because they don't realize how much they can save in the long run.

Should You Buy a Mini Split or Window Unit?

If your home is uncomfortably warm, you'd probably like to cool it down as quickly as possible. A window unit is the path of least resistance because it can be purchased locally and installed quickly. Is it really the best option, though? If you own your home and plan to stick around for a while, a mini split system is probably a much better option. Regardless of what you ultimately decide, you should give plenty of thought to the advantages and disadvantages of both units.

The main things you should consider before buying a portable air conditioner or a ductless system include:

Security - No matter how it's installed, a window air conditioner reduces the security of your home. While it's significantly safer to install one in an upstairs window, you are still making it easier for burglars to gain entry to your home. With a ductless system, contractors only need to drill small holes in outdoor walls. Suction lines, refrigerant lines and power cables are drawn through it to link outdoor and indoor units. You can rest assured that the security of your home won't be compromised in any way.

Convenience - When you use a window unit, you sacrifice an entire window. The room receives less natural light, and you no longer have the option of opening the window to let in fresh air. You can avoid this problem by opting for a ductless system instead. This option allows you to stay cool and comfortable without having to give up an entire window.

Flexibility - While a window AC unit can effectively cool a single room, it can't do much else. Advanced models sometimes have extra features like multiple fan speeds and digital displays. Some even have remote controls. Many ductless systems have remote controls too, though, and they have additional perks that you won't find with window units. Most notably, mini split systems can be set up for zoned climate control, which means that you can adjust temperatures in specific rooms. These systems are known as multi-split systems. As an added bonus, indoor and outdoor units can be positioned in a variety of ways to achieve optimal comfort, efficiency and aesthetic appeal.

Efficiency - In terms of energy efficiency, ductless systems are the hands-down winners. Some window units are ENERGY STAR rated, but they still don't come close to achieving the kinds of SEER ratings you'll find with mini split systems.

Comfort - Window units often seem to have no happy medium. They make rooms too hot or too cold. Ductless systems have specialized sensors that detect small changes in temperature and adjust their speeds accordingly. They are able to do this because they have inverter compressors that are capable of operating at various speeds. What's even better is that ductless systems can also provide heat. The most innovative models feature reversible heat pumps that can add warm air from outside just as easily as they can remove warm air from inside. All of this is achieved with a minimal amount of electricity, so energy bills remain reasonable.

Noise - Most window AC units are noisy. Some models are better than others, but you're not going to find one that is completely unnoticeable. Ductless systems make noise too, but they operate a lot more quietly. If noise is a big concern for you, you'll be much happier with a ductless system.

Price - You may be wondering "How much do mini split systems cost?" and may be dismayed to learn that they are much more expensive than window units. However, they also last for years and use a lot less electricity. They deliver superior comfort for a lot less money over time, so you should be able to recoup the upfront cost without any trouble.

Ductless Mini Splits in a Commercial Space.

Ductless mini splits are a popular alternative to traditional heat pump systems. They can be particularly useful in commercial settings where available space may be minimal, where a ducted HVAC infrastructure doesn’t already exist, or where you may not be able to make structural changes to your building to accommodate a duct network. Ductless minis will also require regular preventive maintenance to keep them working effectively and efficiently.

Ductless Mini Splits in Brief.

Ductless mini splits are just as effective as ducted heat pump systems, but take up much less space. They do not require a ductwork system to provide heating and cooling. Instead, they rely on an outdoor unit (similar to that of a full-size heat pump) that is connected to up to four smaller indoor air handling units. The indoor units are connected to the compressor, condenser and other components in the outdoor unit by power lines, refrigerant pipes, and drains running through a conduit in the wall. The indoor units distribute the cool air produced by the system.

Because mini splits need no ducts, the indoor units can be placed anywhere cooling or heating is required without concern for wasting conditioned air by sending into areas that don’t need it. You can use mini-splits to create a very effective zoned cooling and heating system, or you can combine two or more indoor units in areas that need more conditioning. Placement options are limited only by the length of the cables and pipes connecting the indoor and outdoor units. Ductless mini splits are relatively easy to install, are very efficient and run quietly.

Don’t Forget Maintenance.

Business owners who experience the benefits of ductless mini splits will want to do everything possible to keep them working properly. These units may be smaller than normal, but they still require regular preventive maintenance much like larger systems.

Put in clean filters regularly: The air filters improve indoor air quality by trapping and holding airborne contaminants. They are also extremely important to system airflow. Dirty filters can impede airflow and cause malfunctions or breakdowns. Check filters at least every month, or more often if your site tends to have more particulates in the air. Change or clean filters when they get dirty.

Keep the outdoor unit clean: The outdoor unit also needs plenty of airflow, so take steps to keep it clean and free of obstructions. Make sure trees, shrubs, grass and other greenery is cut far enough back to allow at least two feet of clearance on all sides of the unit and five feet of open space above it. Remove any accumulations of dirt, mud, grass, or other material in the unit’s vents.

Clean and balance fans in the indoor units: Fan blades must be properly balanced and oiled to keep them working properly. The entire blower assembly should also be correctly balanced for smooth operation.

Check refrigerant levels: The system will require a manufacturer-specified level of refrigerant to cool properly. Make sure there is not too much or too little refrigerant in the system and that refrigerant lines are undamaged and tightly connected.

Keep the coils clean: The indoor and outdoor evaporator coils must be kept clean and free of debris and blockages. Check the outdoor coils more frequently since they are in an environment where dirt, grass and other material can accumulate more quickly.

Keep the drains clear: The system provides dehumidification for your indoor spaces, which means there will be water that needs to be drained away. Make sure the drain pans and pipes are clear and not blocked and that water can flow away freely.

Why Is It Important to Use Home Air Conditioner Filters?

Your air conditioner delivers important comfort during the cooling season, helping to keep your home temperature and humidity levels comfortable. If the prospect of living without your AC is more than you can handle, it’s a good idea to maintain your air conditioner regularly to make sure it keeps humming along.

Check out the Energy Star website for useful heating and cooling information that will help you maintain your appliances. You’re likely to notice reduced efficiency and higher cooling costs if you don’t check your cooling unit regularly.

You’ll quickly realize the importance of air conditioning filter use when your cooling bill rises or your family starts getting sick.

Factors.

There are specific factors that determine how often you should change air conditioner filters. If you have pets or if someone in your household smokes, your air conditioner filters will need more frequent changing. If you have family members that suffer from asthma or allergies, you’ll need to keep the filter impeccably clean to make sure you’re filtering out contaminants and allergens. In addition, the time your air conditioner spends running also affects how often you need to change the filter. If you run it 24/7 during the cooling season, you’ll probably need to change the filter every three weeks. If you run it less often, you may be able to get by with changing it every five to six weeks.

Cooling Efficiency.

An air conditioner clogged with debris from a dirty air filter won’t operate efficiently. Your unit will need to work harder to produce less cooling, an unpleasant situation for your wallet. When you change the air filters on a regular basis, you’ll notice that your unit cools your home faster, which reduces the amount of time it has to run. Over time, an air conditioner that doesn’t have to work as hard will last longer with fewer repairs, too.

Clean and Healthy Cooling.

A clean air filter will help keep your indoor air cleaner and more healthy. The EPA considers indoor air pollution to be a significant environmental problem. At the same time, an inefficient air conditioner adds additional waste into the environment, which can contribute to greenhouse gas emissions.

Wear and Tear.

If you make a habit out of running your air conditioner with a dirty air filter, you will eventually notice accelerated wear and tear on the unit. Dirt that escapes the dirty air filter will restrict airflow through the unit, which can fill the coils with debris and make the unit freeze up. Eventually you also may have to replace the compressor of your unit. This will involve hiring a technician, which won’t be cheap.

Choosing a Filter.

Air filters have efficiency values that will help you choose the best filter for your air conditioner. The minimum efficiency reporting value ranges between 1 and 12. The higher the value, the more filtration and cleaning you’ll have with the filter. Be careful, though – it will also take more power to pull air through higher-value filters.
