Hitachi air conditioners overview: error codes, comparison of inverter models

Since 1910, Hitachi has been operating as a global industrial corporation. The development of the enterprise is observed with the status of a workshop with a direction in the copper mining sector. For more than a hundred years, hundreds of products based on modern technical developments have been produced under a well-known brand. All products of the manufacturer are created to meet the needs of consumers according to the trends of the time. The company's management initially preferred to invest financial resources in improving the technologies used in production. Company policy is always aimed at growth, improvement and orientation towards the future.

Air conditioning systems under the Hitachi brand are the standard of technical devices designed to increase the comfort of living of people around the world. Attracting an impressive flow of investments into the production process, the brand carries out constant research and development, and also provides itself with positive results from experimental development. Household multi-split systems are ideal for use in a city apartment and country houses.

The main line of air conditioners

Opportunities to improve the properties of the microclimate in any room are constantly growing. To help people in the fight for clean air come air conditioners, which occupy a solid place in creating comfort in the home and optimal conditions for fruitful work. Modern Hitachi air conditioning systems not only have the usual functions of cooling and maintaining a suitable temperature in the rooms, but also help to combat a number of adverse phenomena:

  • elimination of harmful bacteria and viruses that enter the home of their environment;
  • neutralization of unpleasant odors, tobacco smoke and soot from cooking;
  • humidification and ionization.

Hitachi air conditioners are distinguished by the ability to clean the built-in filters in automatic mode. The technology used to create the equipment completely eliminates the further formation of mold and fungus on the internal elements. In the manufacture of components for air conditioning systems, only stainless material is used. A clear advantage of the products of this brand was a significant reduction in energy consumption, which did not affect productivity. Hitachi equipment is designed to create a perfectly comfortable atmosphere within any facility, blending in perfectly with the environment thanks to its sleek design.

Inverter models

Universal inverter air conditioners do an excellent job of cooling, heating and purifying air in city apartments, country houses and offices. The hitachi inverter split system with wall mounting method is based on the reliable All-dc invertor technology. Such multisplit models differ:

  • high energy efficiency;
  • powerful built-in compressor;
  • stepless flow control;
  • decreasing start-stop cycles;
  • The fan in the indoor unit is treated with silver ions. This protects the parts from plaque, dust, while disinfecting the air.

Domestic air conditioners are equipped with a built-in ventilation function - “air exchanger”. It is the inverter that provides the smoothness of the air flow and the gradual achievement of the desired temperature within the premises. The company presents its customers several lines of inverter systems: "Eco comfort", "Akebono", "Performance".Especially popular among consumers is the Premium series, which is characterized by increased seasonal performance and the presence of motion sensors.

Equally popular models of air conditioners with forced ventilation from the Air Exhanger series. The devices operate in a closed cycle, purifying and cooling the air inside the room. The task of the indoor unit is only to remove the generated heat and condensate. Purification of incoming air masses occurs through a 3-stage system of antibacterial filters.

Rotary Compressor Models

This is a series of non-inverter air conditioners of the luxuri category, which incorporate all the technologies of the future:

  • color options: shade “silver” and “coffee”;
  • depending on the model, the performance is from 2, 2 to 6, 35 kW "
  • minimum noise level in the indoor unit (from 21 dB);
  • built-in filtration system based on "Nano titanium" technology.

The introduction of the latest nanotechnologies into production made it possible to protect indoor climate from carbon dioxide, formaldehydes, unpleasant odors and street dust penetrating from the external environment. This technical feature will allow not only to delay, but also throw back all the polluted substances back onto the street.

The disinfection process occurs due to UV radiation. The use of bactericidal ultraviolet radiation made it possible to achieve the perfect balance. Hitachi developers applied this method by incorporating an ultraviolet lamp into the unit. Air passing through the filter is thoroughly cleaned and disinfected with short-wave ultraviolet light.

Industrial air conditioning

Multizone split systems are inverter models of air conditioners, characterized by the presence of an integrated “scroll” compressor. Such models can be connected as follows: one external unit can be connected to four internal ones (maximum). Multizone air conditioning is distinguished by such features as:

  • cool and heat the air, excluding direct air flow to a person;
  • digital control servo;
  • integrated control board and microprocessor program;
  • Thanks to the drainage pump, condensate rises to a height of 6 cm.

Such cassette models became the first inverter-type air-conditioning systems, allowing for simultaneous heating in several areas of the facility, thanks to the Multizone technology. Winter set of equipment allows for room maintenance at low temperatures to -20 ° C. All models can be easily distinguished by the presence of VRV or VRF marking, while the channel VRV installation will achieve the desired performance in the microclimate at public facilities due to increased power and optimal performance. Installation of the Hitachi Multizone air conditioner is done directly on the ceiling surface, making it virtually invisible in space.

Mobile and window models Hitachi

Among the popular models, outdoor appliances are also in high demand. In such a mobile air conditioner, it is allowed to set both vertical and horizontal airflow modes. Mobile installation settings allow you to:

  • heat the room temperature to the desired level;
  • automatically maintain the microclimate in the rooms at the optimum elevation;
  • enable and disable climate equipment at a set time due to the built-in timer.

The entire line of window devices is characterized by ease of regulation and installation speed. The main characteristics of the models include:

  • several cooling modes;
  • air supply adjustment system;
  • automatic distribution due to smooth movements of the external grill.

Such devices can cope with the tasks of split systems, but it is much more mobile and compact.
