Spare parts and accessories for split air conditioning systems

Air conditioners that create a favorable microclimate in apartments, private houses and offices have become an integral part of a comfortable life. Intensive operation in the hot season, non-observance of the rules for caring for the split system leads to minor and major breakdowns. To eliminate them and restore the working condition of climatic equipment, you will need accessories for air conditioners.

Consumables: what you need for installation

Buying a modern split system is the first step towards cool and fresh indoor air. The technique requires proper installation and start-up. For work, installers need consumables for air conditioners:

• Copper pipe in coils used for the device of the freon line. The metal is resistant to refrigerant and corrosion.
• Thermal insulation for pipes - material from foamed polyethylene Energoflex, rubber products K-Flex.
• Reinforced tape for winding pipes, sealing seams.
• Solder and threaded fittings, brass nuts, service fittings, angles.
• Three or five-core electrical cable with a cross-section of 1.5-2.5 mm.
• Flexible plastic hose for drainage.
• Siphon with a hydromechanical seal for draining condensed moisture into the sewer.
• Brackets and hardware (anchors, screws, bolts, nuts) for mounting the outdoor unit. A protective fence in the form of an anti-vandal lattice. The design protects the outdoor unit of the air conditioner from damage and theft.

Consumables include refrigerant. Liquefied gas is required to refuel the air conditioning system in the event of a leak. The type of refrigerant used in the equipment is indicated in the specifications and on the nameplate. Common brands: freon R22, R401a, R407c. Gas is sold in cylinders of different color and packaging volume.

Common causes of breakage

A decrease in the intensity of a cold stream, an unpleasant odor, knocking and other minor problems require clarification of the causes of their occurrence. Its operation directly depends on the professionalism of the installers of climatic equipment. Installation of blocks at an angle, poor-quality flaring, bending of pipes and other shortcomings lead to problems in the operation of equipment. Common causes of instrument malfunction include:

1. A sharp surge in the voltage in the electrical network. Air conditioners are sensitive to overloads and voltage surges. The control board, fan motor and other electrical components burn out.
2. If ice builds up on the outdoor fan, the relay will burn out.
3. Long-term operation at maximum power quickly wears out the main components of the split system. The compressor is particularly affected. The situation arises with the wrong choice of the power of the climatic technology. A system with a low cooling capacity is installed in a large room.
4. The indoor and outdoor units of the air conditioner are equipped with filters to capture dust and debris. In the absence of maintenance (cleaning), parts cease to cope with contamination of mechanisms and air. As a result, dust sticks to the fan and the impeller breaks.
5. Freon leakage in places of loose adhesion or through cracks worsens the production of cold, leads to icing of the tubes and the heat exchanger.

Mechanical wear of parts and assemblies of a split system is one of the causes of breakdown.The service center specialists diagnose the equipment and indicate malfunctions. Filters, sensors, relays and other parts with a limited service life are subject to replacement.

It is better to buy spare parts for split systems and consumables yourself. The required part may not be in the service center, and the wait for delivery will drag on for months.

Component overview

The breakdown of the climatic equipment deprives the usual comfort on a hot day. To correct the situation as soon as possible, it is necessary to find a replacement for the failed unit. The catalogs of spare parts for air conditioners offer components that are most in demand for repairs:

• 4-way valve for reversing the circulation of freon, switching between cooling and heating modes.
• The compressor is the main piece of equipment that circulates the refrigerant along the working circuit. Voltage surges, improper installation, violation of the operating recommendations lead to a breakdown of the unit. The compressor is the most expensive part of an air conditioner. In models of the middle and budget class, piston and rotary mechanisms are installed. Inverter compressors are used in premium air conditioners.
• Starting capacitor - the part is designed to start the compressor. It may explode or leak as a result of overheating. For replacement, a capacitor of similar capacity is required.
• Filters are consumables for air conditioners, which are changed every 3-6 months. The frequency depends on the operating conditions. Coarse and fine filters are installed in the indoor unit. Their function is to rid the conditioned air of dust and debris. Models with special properties remove odors, bacteria, viruses, fungus. Common options for replaceable filters: carbon (carbon), catechin, antibacterial, treated with silver ions, photocatalytic. Parts are made on paper and synthetic base. Some split systems are equipped with an indicator indicating the need to replace the filter.
• Drainage pump - a pump designed to drain condensate. There are two types of models - flow-through and storage.
• The impeller or turbine of the indoor unit fan is fitted to the motor shaft. The new part is selected by diameter, length and type of attachment.
• The impeller of the outdoor unit is a blade. The selection is carried out according to the outer diameter, shaft diameter, type of attachment.

• 

  Indoor unit temperature sensor. Spare parts differ in nominal resistance. The indicator is indicated by kOm, common models are 5,10,15, 20 kOm.

• The remote control is one of the climatic equipment accessories that needs to be replaced periodically. In case of loss, it is problematic to turn on the split system and set the current mode. There are universal options to suit different brands of air conditioners. They support up to 1000 models and have an extensive code base. In addition to universal consoles, remote controllers from leading manufacturers of climatic equipment are sold, designed for a specific series.
• Fan motor - there are 2 units in the split system. The motor of the external unit is made of metal, the internal unit is made of plastic. Most often, motors with multiple windings are installed. To buy an optimal replacement, you need data from the nameplate of the motor and air conditioner. The unit is selected according to power, dimensions, shaft dimensions, speed and direction of rotation.
• Control module - when a network overload occurs, the control board burns out. Electronic modules are manufactured in different factories. A suitable option is found by the brand and series of the air conditioner.
• Air conditioner casing - mechanical damage leads to the loss of the decorative appearance of the blocks. The wear of the housing parts affects the performance of the heat exchanger and the fan. Buyers are offered a separate front panel and rear part of the split-system modules.

Selection criteria for air conditioner parts and accessories

At first glance, the problem of finding and replacing components for climatic equipment seems to be a difficult matter. In specialized online stores, accessories for air conditioners and consumables are offered at affordable prices. The range includes spare parts for products from leading companies: LG, Carrier, Daikin, Mitsubishi Electric, Fujitsi, Gree, Samsung, Ballu. The purchase of original brand components is recommended. This will guarantee the spare part. If you have any difficulties with choosing a model of components, contact the technical support service.

Some parts of air conditioners are interchangeable, for example, the compressor of one brand meets all the characteristics and dimensions of the unit of another manufacturer. Also universal parts include pressure sensors, capillary tubes, four-way valves.
