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

Since 1910, Hitachi has been operating as a global industrial corporation. The development of the enterprise is observed from the status of a workshop with a direction in the copper mining industry. 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 designed to meet the needs of consumers in accordance with the trends of the times. The company's management initially preferred to invest financial resources in improving the technologies used in production. The company's policy is always aimed at growth, improvement and future orientation.

Air conditioning systems under the Hitachi brand are the standard of technical devices designed to improve the comfort of living for people around the world. By attracting an impressive flow of investments into the production process, the brand conducts constant research and development work, and also ensures itself positive results from research and development. Household multi split systems are ideal for use in a city apartment and country houses.

Main lines of air conditioners

Opportunities to improve the properties of the microclimate in any room are constantly growing. Air conditioners come to the aid of a person in the struggle for air purity, which take a strong place in creating comfort in the house and optimal conditions for fruitful work. Modern Hitachi air conditioning systems have not only the usual functions of cooling and maintaining a suitable temperature regime in the premises, but also help to fight a number of adverse phenomena:

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

Air conditioners from Hitachi are distinguished by their ability to automatically clean built-in filters. The technology used to create the equipment completely excludes the further formation of mold and mildew on the internal elements. In the production of components for air conditioning systems, exclusively 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 in any way. Equipment from Hitachi is designed to create a perfectly comfortable atmosphere within any object, ideally fitting into the environment, thanks to its laconic design.

Inverter models

Universal inverter air conditioners do an excellent job of cooling, heating and purifying the 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;
  • smooth flow control;
  • reduction of "start-stop" cycles;
  • the fan in the indoor unit is treated with silver ions. This protects 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 ensures the smooth flow of air and the gradual achievement of the desired temperature within the room. The company presents to the attention of buyers several lines of inverter systems: "Eco comfort", "Akebono", "Performance". The "Premium" series is especially popular among consumers, characterized by increased seasonal performance, as well as by the presence of motion sensors.

No less popular are the 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. The incoming air masses are cleaned through a 3-stage antibacterial filter system.

Rotary compressor models

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

  • color options: shades "silver" and "coffee";
  • depending on the model, the capacity ranges 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 nano-developments into production has made it possible to protect the indoor climate from carbon dioxide, formaldehyde, unpleasant odors and street dust penetrating from the external environment. Such a technical feature will allow not only to detain, but also to throw back into the street all the detained pollution.

The disinfection process takes place thanks to UV radiation. The use of germicidal ultraviolet light allowed to achieve an ideal balance. Hitachi developers applied this method by embedding an ultraviolet lamp in the unit. The air passing through the filter is thoroughly cleaned and disinfected using short-wave ultraviolet light.

Industrial air conditioning systems

Multi-zone split-systems are inverter models of air conditioners, distinguished by the presence of a built-in "scroll" compressor. Such models can be connected according to the following scheme: it is permissible to connect one external unit to four internal (maximum). The multi-zone air conditioner is distinguished by such features as:

  • cool and heat the air, excluding the direct air flow onto the person;
  • digital control servo drive;
  • built-in control board and microprocessor program;
  • thanks to the drainage pump, the condensate rises to a height of 6 cm.

Such cassette models became the first inverter-type air conditioning systems that allow simultaneous heating in several areas of the facility, thanks to the Multizone technology. The winter set of equipment allows for maintenance of premises at low temperatures down to -20 ° C. All models can be easily distinguished by the presence of the VRV or VRF markings, while the channel VRV installation will allow you to achieve the desired indicators in the microclimate in public facilities due to increased power and optimal performance. The installation of the hitachi “Multizone” air conditioner is carried out directly into the ceiling surface, which makes it almost invisible in space.

Hitachi mobile and window models

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

  • heat the room temperature to the desired mark;
  • automatically maintain the microclimate in the rooms at the optimal level;
  • turn on and off climatic equipment at a set time due to the work of the built-in timer.

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

  • several cooling modes;
  • air supply control system;
  • automatic distribution due to the smooth movements of the outer grille.

Such devices quite cope with the tasks of split systems, but at the same time they are much more mobile and compact.

  • malfunctions in the external module;
  • overheating of internal coils;
  • an error in the connection of the outdoor, indoor unit and board;
  • jamming of the outer louver grille;
  • interruptions in the speed of rotation of the fan motor;
  • the need to charge the device with refrigerant.

User reviews

Based on the reviews of real buyers of Hitachi products, it has obvious "advantages":

  • a variety of heating / cooling modes;
  • minimum rate of temperature drop, even in large rooms;
  • function of ionization and cleaning of the microclimate;
  • automatic flow direction;
  • touch mode based on built-in motion sensors.

All models, according to buyers, are made of high quality plastic. Air conditioning units fit perfectly into any interior. The intensive heating mode is indispensable in the period of insufficient intensity of central heating during the cold season.

The disadvantages of goods include:

  • high cost of products and services;
  • frequent refueling of freon at increased loads during the summer heat;
  • lack of backlighting on some models.
