Few people know that the first room air conditioner has been released by General Electric in 1929. As the refrigerant in the device used ammonia, which the pair are not safe for human health. For this reason, the air conditioner compressor and condenser were made on the street. But this means that the proposed device has been most of this split-system! It is true, then the development of climate technology has gone a different direction and the air conditioner, which consists of two blocks, remember only 30 years old, but already in Japan. In 1961, Toshiba launched its first mass production system consisting of two units: the external and internal. In the same season the company Sanyo "taught" split-system to work not only on a cold, but also to heat. It was then stuck behind them and their current name (from the English "to split" - to divide, to split). Only now the designers carried the compressor on the street is not for security reasons and to reduce noise in the room. And indeed, it is possible to reduce it in one fell swoop by 6-9 dB (A), in human perception means 4-8 times! Suddenly opened, and another advantage - the freedom in choosing a site for the indoor unit. Now the room air conditioner rid of hard pegs to the window opening. Internal blocks of modern split systems can be mounted on a wall, ceiling, floor, and even hide behind a false ceiling. However, the most widely used air conditioners wall mounting. Compactness, lower compared with other types of cost and ease of installation have led to what exactly they account for the lion's share of sales, especially in homes and small offices. Not surprisingly, this type of split-systems is developing most rapidly, about them and will be discussed in this review. In the face of increasing competition, leading companies almost every year offering something new. So this season in the Russian market for the first time presented dozens of interesting models. First of all, attention is drawn to the emergence of a large number of air conditioners inverter. They differ from traditional models is the ability to smoothly adjust the power. In a typical split-system of the engine compressor has only two modes: on and off. This air conditioner operates with short pulses: harness oneself to full capacity, bring the temperature to an optimal and falls asleep. Inverter operates somewhat differently: after the air got a nice cool, air-conditioning is not switched off, and reduce turnover and maintain the temperature at a given level. As a result, no permanent on / off compressor that has a beneficial effect on its longevity. Air Conditioners Inverter 20-30 per cent more economical than conventional, so where electricity is expensive, for example, in Japan, they have long dominated the market. In the last two or three years, the demand for this technology is growing steadily and outside the country of the rising sun. If before 1998 the Russian market was represented only 5 models of split-type inverter, today there are exactly seven times. This equipment is offered Hitachi, Daikin, Mitsubishi Heavy, LG, Chofu, Mitsubishi Electric, Panasonic, Sharp, Airwell, Electra, Fujitsu General, Funai, General Electric, Toshiba (the company located in the order of the number represented in Russia inverter models). True, in Russia, the main incentive to buy the inverter air conditioner is not the economy, and greater comfort. He quickly brings the temperature to a predetermined and precisely maintains it at the appropriate level. True, to force out the air conditioner to the desired mode is possible without the help of the inverter. Company Daikin, Daewoo, Hyundai, LG and Samsung have solved this problem by introducing a special function. It is called differently: "Powerful Mode", "Turbo", "Jet Cool", but the essence is: when you turn on air conditioner gives 110 percent of rated power, so the time delay is reduced by about 30 percent. And Mitsubishi Heavy forced start automatically, but only in the heating mode. Another plus inverter - the lack of periodic inclusions of the indoor fan at full capacity, coupled with an abrupt change in noise level. True, many NON INVERTER models work exceptionally quiet. The minimum noise level of recent developments Daikin, Mitsubishi Electric, Panasonic, Sharp, Sanyo, Tadiran virtually indistinguishable to the human ear. This is achieved in various ways. At Daikin and Toshiba, the indoor fan has a variable pitch blades, which eliminates the possibility of resonance frequencies. A number of air conditioners has a fourth, a reduced fan speed indoor unit, which allows to significantly reduce noise levels. Do DeLonghi and Mitsubishi Electric switching to reduced turnover occurs when you enable a comfortable sleep at Fujitsu General - in the "super-kvayt, in Chofu - in the" soft ", while Hyundai - during the transition to low-noise program. Virtually all modern split systems are equipped with automatic blinds able to dissipate the air flow up and down. In 1998, Fujitsu General has released a model that can automatically distribute the cooled air more, and right-left. The result - the most even distribution of flow across the air-conditioned area. Today, these conditioners are supplied in Russia has three companies: Daikin, Daewoo and Airwell. Incidentally, the company Airwell, Daikin and Electra have found another way to make air distribution more uniform. They suggested that the internal wall mounting blocks, which suck air from the front, cool and serve it up, down, left and right. Increases comfort and availability features "I Feel". It allows you to transfer the measuring point of temperature on the remote control. As a result, the desired temperature is created directly by geographical location owner. Just do not abuse it - if you sit in the farthest corner of the room and put 19 degrees Celsius, people in the immediate vicinity of the device may simply freeze. Today, air conditioners c function "I Feel" offer Airwell, Electra, and Mitsubishi Electric. It is necessary to touch on such topics as the work of a split system at low temperatures. When the thermometer drops below minus 10-15 degrees Celsius, the air conditioner is better care of. It was too expensive is a "toy" to drive her there, where will fit a cheap oil cooler. The fact that the cold wear conditioner increases many times, and when used regularly in the winter it is unlikely to hold out longer than 3-4 years, instead of the 6-8. The fact that the grease in the cold loses its properties, and the most expensive unit in any air-conditioner - the compressor runs for wear. That is, chasing him into the cold - it's like to ride at minus thirty on unheated car. For this reason, some brands such as Sanyo, is blocked, interrupting air conditioner when the temperature drops below minus 9 degrees. However, if you want to warm up and at minus 20 C, a number of companies make every effort to satisfy your desire. Many manufacturers equip compressor crankcase Tan, then grease the frost does not thicken. Defrost and heat exchanger external unit to the cold, he did not look like a snowman. Do DeLonghi air conditioners and Daewoo to more effectively fight the ice has several modes of defrosting. And some models of the domestic producer (Elemash) and Airwell and Carrier equipped with electric heaters that can operate "on heat" in any frost. Of course, TEN mercilessly eats electricity, but the compressor at this time resting. In order to protect the external air conditioner unit from corrosion and maintain their attractive appearance, a number of firms invited to make housing outdoor units from high-impact plastic. Today, this path has also taken place Fujitsu General, Sharp, Chofu. There is a plastic outer blocks from Hitachi, while the new models and Daikin DeLonghi plastic made only the most vulnerable to rust. Does not stand still and cleaning the air. Most modern models equipped with a triple filter system. It is well known for the development of Samsung, had offered air conditioning, all the interior are covered with a special antibacterial compound. Various anti-bacterial coating, the indoor fan, heat exchangers, filters and control panels used Daikin, Fujitsu General, General Electric, Panasonic, Sharp, Sanyo. Engineers have proposed an interesting novelty LG. In the air cleaning system, called Plasma, the air flow is passed through a section with a voltage of 4800 volts, resulting in all organisms and viruses are killed, and chemical impurities and odors can be decomposed into harmless components. Concern for the environment manifests itself in using new ozone-friendly refrigerants. This season, two manufacturers - Daikin and Mitsubishi Electric - have already provided a wide range of models that work using freon R407C and R410A, a few of these air conditioners offers Airwell, and in May the company will join Fujitsu General. On the refrigerant R407C can run many models of Sanyo, shipped to Russia with the traditional Freon R22. While the model for new refrigerants somewhat expensive, but in the next few years all the leading manufacturers suggest move fully on the issue of climate technology, safe for the ozone layer. And in Sweden, Norway, Germany and several other European countries, a ban on the sale of air conditioners with the old Freon enters into force from next year.
