Spare parts and accessories for split air conditioning systems

Air conditioners, creating 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 HVAC equipment, air conditioning components will be required.

Consumables: what you need for installation

Buying a modern split system is the first step to cool and fresh indoor air. The technique requires proper installation and launch. For work, installers need supplies for air conditioners:

• The copper pipe in the bays used for the device of the freon highway. The metal is resistant to refrigerant and corrosion.
• Thermal insulation for pipes - Energoflex foam material, K-Flex rubber products.
• Reinforced tape for wrapping pipes, sealing joints.
• Brazing and threaded fittings, brass nuts, service fittings, elbows.
• Three or five-core electric cable with a cross section of 1.5-2.5 mm.
• Flexible plastic hose for drainage.
• Siphon with a hydromechanical shutter to drain condensed moisture into the sewer.
• Brackets and hardware (anchors, screws, bolts, nuts) for mounting the outdoor unit. Safety guard in the form of an anti-vandal grille. The design protects against damage and theft of the outdoor unit.

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 volume of packaging.

Common Causes of Breakage

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

1. A sharp surge in 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. The appearance of ice on the fan of the outdoor unit leads to the burning of the relay.
3. Continuous operation at maximum power quickly wears out the main components of the split system. The compressor is particularly affected. The situation arises when the power of the climate technology is improperly selected. A system with poor cooling capacity is installed in a large area.
4. The indoor and outdoor units of the air conditioner are equipped with filters for trapping dust and debris. In the absence of maintenance (cleaning), the parts cease to cope with the pollution of mechanisms and air. As a result, dust adheres to the fan, the impeller breaks.
5. Leakage of freon in places of loose adhesion or through cracks worsens the production of cold, leads to icing of the tubes and heat exchanger.

Mechanical wear of parts and assemblies of a split system is one of the causes of failure. Service center specialists diagnose equipment and indicate problems.Replace filters, sensors, relays and other parts with a limited life.

Spare parts for split systems and consumables are better to buy on their own. The necessary details may not be in the service center, and the waiting for delivery will drag on for months.

Component Overview

Damage to the climate equipment deprives the usual comfort on a hot day. In order to correct the situation as soon as possible, it is necessary to find a replacement for the failed node. The catalogs of spare parts for air conditioners offer components that are most in demand during repair:

• 4-way valve for reversing freon circulation, switching cooling and heating modes.
• Compressor is the main component of the equipment, providing the circulation of refrigerant along the working circuit. Power surges, improper installation, violation of operating recommendations leads to damage to the unit. A compressor is the most expensive part of an air conditioner. In the models of the middle and budget class, piston and rotational mechanisms are installed. Premium air conditioners use inverter compressors.
• Starting capacitor - the part is designed to start the compressor. Overheating may cause it to explode or leak. A replacement capacitor of a similar capacity is required.
• Filters are consumables for air conditioners that change 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, fungi. Common options for replaceable filters: carbon (carbon), catechin, antibacterial, treated with silver ions, photocatalytic. Parts are made on paper and synthetic basis. Some split systems are equipped with an indicator that indicates the need to replace the filter.
• Drainage pump - a pump designed to drain condensate. There are two types of models - flow and storage.
• The impeller or fan turbine of the indoor unit fan is put on the motor shaft. The new part is selected by diameter, length and type of mount.
• The impeller of the outdoor unit is a blade. Selection is made according to the outer diameter, shaft diameter, type of fastening.

• 

  The device externally block split system

  The temperature sensor of the indoor unit. 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 accessories of HVAC equipment that periodically requires replacement. In case of loss, it is problematic to turn on the split system and set the current mode. There are universal options suitable for controlling air conditioners of various brands. They support up to 1000 models, have an extensive code base. In addition to universal remotes, PDUs from leading manufacturers of HVAC equipment are sold, designed for a specific series.
• Fan motor - in the split system there are 2 units. The motor of the external unit is made of metal, the internal - of plastic. Most often, motors with several windings are installed. To purchase the optimal replacement, you need data from the nameplate of the motor and air conditioner. The unit is selected by power, dimensions, shaft size, speed and direction of rotation.
• Control module - if a network congestion occurs, the control board burns down. Electronic modules are manufactured in various factories. A suitable option is found by brand and series of air conditioner.
• Air conditioner case - mechanical damage leads to the loss of the decorative appearance of the blocks. The wear of the body parts affects the performance of the heat exchanger and fan. Buyers are offered separately the front panel and the rear of the split system modules.

Criteria for choosing parts and accessories of the air conditioner

The problem of finding and replacing components of HVAC equipment at first glance seems to be a difficult matter. Specialized online stores offer air conditioning accessories and consumables at affordable prices. The range includes spare parts for products of leading companies: LG, Carrier, Daikin, Mitsubishi Electric, Fujitsi, Gree, Samsung, Ballu. The purchase of original brand accessories is recommended. This will give a warranty on the spare part. If you encounter difficulties with the choice of component model, contact the technical support service.

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

Delivery of the ordered parts is carried out to the house by courier or by mail.
