Review of Komatsu air conditioners: error codes, comparison of industrial and household models

The HVAC equipment manufacturer Komatsu is a dynamically developing Chinese company KOMATSU ELECTRIC Co. LTD "located in Hong Kong. Today the company occupies one of the leading places in the development, production and supply of goods around the world. All series of split-systems are produced at the best plant in China "Chigo", equipped with the most modern equipment.

The process of assembling air conditioning systems has been brought to perfection, and the involvement of intermediary organizations is completely excluded. This allows you to constantly monitor any production stage and bring the rate of defective products to zero. The manufacturer has created a network of industrial branches, on the basis of which both the main components and body parts and branded packaging materials are manufactured. The brand has independently mastered the production of such elements as:

• Versatile evaporators.
• Condensers for all models of climatic devices.
• Embedded electronics.

For fifteen years now, the brand has been directing its production and intellectual resources to the development and conquest of the world international market. Currently, finished products are supplied to more than 150 countries around the world.

Main lines of air conditioners and products

The Chigo plant is the main production base not only for Komatsu products, but also for such brands of air conditioners as Mitsubishi Heavy. The complete absence of defective products is the only quality standard that the company is focused on. In addition, the organization was awarded with a distinction for environmental protection, for the introduction of energy-saving technologies and safe production.

Among the models of air conditioners, the following groups of goods are distinguished:

• split system for servicing residential and office buildings;
• household multifunctional "split" based on inverter compressor control;
• powerful cassette installations for production and semi-production purposes;
• floor and ceiling multi-split;
• mobile devices.

The management of KOMATSU ELECTRIC Co. LTD "adheres to the existing strict requirements of the certification bodies of the world market of electronics and household appliances. For example, "Quality Management System" IS0-9001 "," Management System and Environmental Protection "IS0-14000", Certificate "On the level of energy saving of goods in the PRC", Certificate of Compliance "RosTest", Certificate of the European Union "CE", Certificate of Compliance the level of safety of goods "ASS" (Australia) and others.

Wall mounted air conditioners

Installing an air conditioner on one of the walls of a room is the most common way of installing HVAC equipment. The indoor unit installed in the room practically does not occupy the space of the room, gradually brings the microclimate indicators to the optimally suitable indicators. Among the popular Komatsu household air conditioners, there are both inverter and non-inverter models:

1. Series of inverter air conditioners: "V2", "V4", "V5", "V7".
2. Popular series of non-inverter models include “H1”, “H2”, “H4”, “H7”, “H5”, “BY1”, “BY2”.

All split systems in this category consist of two interconnected blocks: internal and external.Depending on the specific model of equipment, Komatsu air conditioners, judging by the reviews, are capable of servicing objects up to 50 m2. The device perfectly copes with the task of cooling, heating and air ventilation. It is quite easy to operate such equipment: the kit includes a remote control that allows you not only to turn the device on and off, but also to set the most suitable operating mode.

What is the difference between wall-mounted multisplit of the KOMATSU company and similar products of competing companies? Here are some clear benefits:

1. Reliable Japanese compressors.
2. A complete set of basic and additional options, including the "Restart", "Sleep", "Turbo" modes.
3. Efficient filtration system including catechol and catalytic filter.
4. 3D airflow option that distributes the air flow evenly throughout the space.
5. Built-in ionizer.
6. Timer.

All models of the indicated series are equipped with a self-cleaning mode, and the function of locking the set settings will protect against unintentional resetting. Another important feature of the brand's wall line is their ability to cool the air even in an extremely hot summer, up to + 45 ° C. It is possible to set up the device to heat the room at ambient temperatures down to -10 ° C.

Cassette climate systems

Cassette air conditioners "Komatsu" as well as ducted air conditioners must be installed in the space between the ceiling and the suspended ceiling. Such equipment belongs to the category of semi-industrial installations. The difference between air conditioners-"cassette" is that the distribution of cooled or hot air occurs through the lower part of the built-in structure.

The use of such models is most advisable in public, commercial and office premises. The main technical characteristics of cassette models are:

• durable compressors from Hitachi and Sanyo;
• "Hold" mode;
• timer and sleep mode;
• options for the size of the outer lattice: 60X60 cm or 1.20mX60 cm for enlarged objects.

The design is thought out to the smallest detail. After the installation has been completed, the outer grille is practically invisible, which does not spoil the overall design of the room. Cooling or heating occurs as evenly as possible, since the air flow is distributed in four directions.

Floor-ceiling multisplit systems

Unlike cassette systems, such equipment does not require a false ceiling. The main difference between this design is the relatively small depth of the block (from 18 to 25 cm). There are two installation options: in a wall surface or in a ceiling. By the way, the further direction of the incoming air flow depends on the installation option. With a wall mount, the air is directed vertically, and with a ceiling mount horizontally.

Thus, the ingress of cold streams on the inhabitants of the rooms is absolutely excluded, and the heat in heating mode will spread smoothly and quickly. In addition, it is possible to regulate the intensity of the device through several speeds, including in the "Turbo" mode. The following characteristics are distinguished from the description of climatic technology:

• Japanese compressor "Hitachi / Sanyo";
• full set of options, advanced functionality;
• temperature control;
• it is possible to heat up, cool the air in the "3-D" blowing mode.

The price of such installations is slightly higher, but the service area is also much larger (up to 140 m2). The entire series of "KFC" is designed to serve trade, office, office facilities, as well as buildings of non-standard shape.

Mobile air conditioners

Komatsu mobile air conditioners are compact portable devices that can work not only as a familiar household air conditioner, but also as a powerful heater. All monoblocks from this brand are united in the “KPT” line. Such air conditioning units do not require installation work. They are ideal not only for residential but also for utility rooms.

As well as other models of multisplit mobile units, they have incorporated all the latest technical developments:

• compressor brand "Toshiba" (GMCC);
• options for operating modes and intensity during operation;
• "Turbo" mode, thanks to which the premises will be heated in a matter of minutes, which is especially important in the cold season.

The wheels built into the bottom of the structure will allow the monoblock to move around the entire space. Side handles make it as easy as possible to move the air conditioner and make it safe. The front louver grill can be installed in several positions. Despite its compact size, such a model can easily cope with objects up to 26 m2.

The instruction for air conditioners includes all the explanations of the symbols available on the unit or panel, and also contains a schematic representation of the installation methods, the purpose of this or that element. The set of branded products includes warranty coupons for service and professional repair of the air conditioner at the regional service center.

Komatsu air conditioner error codes

All multi-split for household and semi-industrial use are equipped with a self-diagnostic function. This option allows the air conditioner to:

• independently detect the error that has occurred;
• show the corresponding code on the display;
• protect the device from the detected threat in auto-mode.

Air conditioner error codes allow you to carry out the next maintenance in a timely manner, establish the cause of the malfunction and choose the right one to eliminate it.
