The outdoor unit of an air conditioner is installed outside of the interior living/working area to release heat and humidity collected from within the building. The parts of the split AC outdoor unit include:
Condenser Coil
The main Outer unit part of split AC. A condenser coil is an essential part that helps remove heat from the refrigerant gas, resulting in the conversion of the gas into a liquid. During this process, the heat exchange takes place with air surrounding the coil. After the heat is removed, cool air is released back inside the space where the air conditioner is located.
Condensing Unit/Fan Motor
As a part of the outside air conditioner unit, the main function of the Condensate Fan Motor is to dissipate the heat from the refrigerant gas and convert it into a liquid with the help of the cooling fan. The motor helps operate the fan to pull in the heat from the surrounding air into the refrigerant coil, and at the same time push back cool air in the environment.
Compressor
The AC compressor outside is the heart of the entire air conditioner system as it circulates the refrigerant throughout the indoor and outdoor unit parts. It's a pump that compresses the refrigerant gas so that it can move through the condenser where it will release heat and cool down to a liquid.
Discharge Line
After the refrigerant has released its heat through the condenser coil, it becomes a high-pressure liquid. The high-pressure liquid is then sent to the evaporator coil through the discharge line. The evaporator coil is commonly located within the indoor air conditioning unit.
Refrigerant
It's the cooling liquid that moves through the air conditioning system to absorb heat and cool down the air. Refrigerant is the main liquid used for active cooling in all types of air conditioners.
Fan Blade
Fan blades of the outdoor air conditioner unit are specially designed to pull in heat from the surrounding air into the condenser coil to initiate the process of releasing the heat from the refrigerant.
Accumulator
The accumulator is a component of an outdoor air conditioner unit. It is designed to hold excess refrigerant and prevent it from returning to the outdoor unit in case there is a blockage in the evaporator coil located within the indoor air conditioning unit.
Mounting Bracket
Used for securely mounting the outdoor air conditioner unit to the wall of a building or another surface.
There are many applications for both commercial and residential AC outdoor unit parts.
Replacement of old air conditioners
Many people are replacing their old split air conditioner outdoor units with newer, more efficient models. This trend will likely increase as people look for ways to cut their electricity bills and combat climate change.
Growing demand for home air conditioning
The demand for home air conditioning is expected to skyrocket as more people in developing countries gain access to disposable income. In China, for instance, it's not unusual for an entire home to be air-conditioned. This trend is expected to increase the demand for outdoor air conditioning units and their replacement parts exponentially.
Expansion of commercial spaces
Many commercial spaces now have to be air-conditioned. This includes large commercial buildings as well as offices, hotels, hospitals, schools, and shopping malls. Most commercial spaces use the split AC model because it is easy to cool large areas. The huge demand for commercial air conditioning units will likely increase the demand for outdoor parts to replace old ones.
Outdoor units in harsh environments
Outdoor air conditioner splits that are installed in very dry or wet, corrosive, salt-laden, polluted or high-altitude environments may need to have their parts replaced. Because they are exposed to the elements more than indoor ones, they age and degrade faster. Consequently, the demand for replacement parts for split outdoor AC units in these harsh environments will increase.
A few things should be taken into consideration when selecting outdoor AC parts for units. Indoor and outdoor AC components must be compatible. After all, they were designed to work together closely to maintain a comfortable room temperature. Assess the current outdoor AC unit to determine if its parts are available. Pay close attention to the model number of the unit.
Consider the effectiveness of potential replacements. An opportunity to boost a home's energy efficiency may lie within the need for a replacement part or replacement unit. Higher SEER ratings can lead to greater energy efficiency and savings for consumers.
The quality and warranty of new components must also be researched before buying. Do the components come with a warranty? How long is that warranty good for? What critical details about the materials and construction of the parts should be known to the buyer? Get answers to these questions before purchasing.
While negotiating bulk buys, explore the pricing models. Consider typical pricing for individual parts vs. bulk purchases of outdoor AC parts. Is there a significant difference in costs? Are there better margins for customers when bulk purchases are made? These are some questions to consider when pricing for inventory.
Q1: Why is it important to maintain the outdoor part of an AC unit?
A1: Since it has important components like the condenser coil, compressor motor, and fan, the AC outdoor unit removes heat from the indoors. Its proper functioning is vital for the overall performance of the split air conditioner. Without regular maintenance, parts of the outdoor AC unit may get stuck, wear out, or break.
Q2: What is the lifespan of outdoor AC unit parts?
A2: Regular maintenance can help split AC unit parts last longer. The condenser coil can last for over 10 years, while the compressor can last up to 15 years or more with proper care and troubleshooting. The fan motors may also last for about 10 years or longer.
Q3: What are some outdoor AC unit parts that often need replacement?
A3: The outdoor unit is more prone to damage and wear and tear due to weather conditions and lack of ventilation. Components like the rubber grommets, seals, and insulation that are exposed to moisture may mildew or rot and need replacing. Condenser coils are also prone to corrosion and will need replacements over time.
Q4: How many years does a split AC outdoor unit last?
A4: A quality indoor/outdoor split AC may last for approximately 15-20 years. However, this largely depends on the frequency of maintenance, exposure to weather elements, installation, and the quality of the product.
