Middle East Systems

However, since 1931, when it was invented safe for the human body, the refrigerant Freon, the designers felt it best to collect all the units and sets air-conditioner in one case. So appeared the first window air conditioners, the distant descendants of which are successful in our day. Moreover, in the U.S., Latin America, the Middle East and India, window air conditioners are still the most popular type. Reasons for their success are obvious: they are about half the price of similar capacity split systems and their installation requires no special skills or expensive tools. Long time leaders in the latest developments ventilation and air conditioning were American companies. But in the late 50's and early 60's initiative is strongly shifted to the Japanese. Later they identified the face of modern industry climate. In 1958, Japanese , Daikin has developed the first heat pump, thus, by teaching air conditioners run on heat.

Three years later, began mass production of split systems. Since 1961, when the Japanese Toshiba company first launched in a batch production of air conditioner, split into two blocks, the popularity of this type of hvac equipment is constantly growing. Due to the fact that the most noisy part of the air conditioner compressor is now put to the street, in rooms are equipped with split-system is much quieter than in rooms where work window air conditioners. The second big plus is the ability to place the indoor unit split systems in any convenient location. Now available many different types of internal devices: Wall, Ceiling, floor and recessed in the ceiling, and duct tape.

It is important not only in terms of design – different types of indoor units can to create the most optimal distribution of cooling air in the premises of some form and function. In 1969, Daikin Air Conditioning released, in which a single external power to work more than one internal. So there were multi-split-system. Today they can include from two to six internal units of different types. In 1981, Toshiba has offered the first split-system that can smoothly adjust its production capacity, and already in 1998 Inverters year took 95% of the Japanese market. The last of the world's most popular types of air conditioners-VRV-system have been proposed by Daikin in 1982. Central intelligence systems such as vrv consist of external and internal blocks that can be removed from each other at 100 meters, with 50 of them vertically. Installation of VRV-systems is quite simple and does not take much time. Installation can even lead after finishing work, and in acute necessary – without interrupting your office. Chance and phased commissioning of new capacities, with separate floors or buildings. Through a variety of unique advantages vrv system was a serious competitor to traditional central air conditioning systems and, in some countries such as Japan, virtually forced them off the market. Of course, this progress in the development of hvac equipment is not over, but now has improved existing types of equipment. There are new features, design changes, development of new refrigerants.
