Split ac outdoor unit parts

Types of Split AC Outdoor Unit Parts

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.

Specification and maintenance of split AC outdoor unit parts

This assembly usually includes circuit boards, capacitors, contactors, relays, fuses, and other components. The electrical assembly mainly provides power transmission and control signals, which are crucial for the operation and safety of the air conditioner. Circuit boards act as the brain of the outdoor unit, controlling its functions and communicating with other parts. Capacitors store and release electrical energy to maintain stable operation. Contactors are electromechanical switches that control the on/off state of electrical circuits. Relays are used to protect and switch different circuits, while fuses are protective devices that prevent excessive currents from damaging the circuit. Together, these components ensure the correct operation of the outdoor unit and protect it from potential hazards.
• Mounting brackets: The mounting brackets are important support structures that secure the position of the outdoor units of air conditioners. They usually have a robust design and are made of steel to support the weight of the outdoor units and ensure their stability. Moreover, the mounting brackets can absorb vibration and impact, protecting the outdoor units from damage. In addition, mounting brackets facilitate the installation and adjustment of outdoor units, ensuring they are properly positioned. Brackets matched with the outdoor unit help ensure the secure and reliable installation of the air conditioner.

Maintenance

• Keep the outdoor unit clean: Regularly clean the surface and the surrounding environment of the outdoor unit to remove dust and debris. Clean the heat exchange coils and keep them ventilated.
• Check the mounting brackets and shock pads: Check the mounting brackets and shock pads at regular intervals to ensure they are not loose or damaged. Retighten and replace them as needed to maintain the stability of the outdoor unit.
• Maintain the cooling fan: Keep the cooling fan clean and ensure it is free of debris and blockages. Check the operation state of the fan and repair or replace it if there are any abnormal conditions.
• Check the pipeline: Check the refrigerant pipelines and water drainage pipes on the outdoor unit, ensuring there are no leaks, blockages, or damages. Repair or replace the damaged parts as needed.
• Pay attention to anti-corrosion and anti-rust: Apply anti-rust paint or coatings to the outdoor unit periodically to extend its lifespan and enhance its durability against the elements.
• Professional maintenance service: Consider employing professional maintenance service personnel for regular inspections and maintenance, ensuring outdoor units operate optimally.

Scenarios of split AC outdoor unit parts
