Before starting to work on installation, purchase the necessary installation tools and accessories, and then carefully examine the technical documentation with the manufacturer's particular model of air conditioner. 1. Selecting a location under the air conditioner make sure that the location of the air conditioner will not adversely affect its operational and technical characteristics. 1.1. Selecting a location for the indoor unit location must be sturdy to withstand the weight of the air conditioner location should provide good air circulation location should be convenient for water drainage. That part of the drainage pipe that sits inside the room should be as short as possible. In addition, make sure that envisaged for the culvert will not inconvenience neighbors. The location should be convenient for adjustment and maintenance of place should not be exposed to direct sunlight near the inlet and outlet air conditioner should be no obstacles 1.2. Selecting a location for the outdoor unit location must be such that the challenged from the block hot air does not cause nuisance to neighbors when choosing a place to consider occurs when the air conditioner noise location must have a solid foundation. Shaky foundation is not safe, in addition, it can cause the appearance of excess noise. Do not place the AC on the ground. Avoid areas where external power may be covered with snow. The location should be such that the heat exchanger was carried out by an efficient location should be convenient for inspection and maintenance of the note that each unit model is the maximum allowable length of the pipeline with the refrigerant and the maximum elevation. 2.

Air Conditioners: Myths and Realities
In recent years, our fellow citizens neizbalovannym faced with such an abundance of modern household appliances and building materials, that many a head went round. But if a microwave oven, Vidic and other hot tub with whirlpool, we still somehow figured out that air conditioning is still causing a lot of questions. However, it is not surprising: in recent years has been written about him so much tales that fit and get confused. Therefore, it is time to clarify this issue. So what is the air conditioner, how it works, and what problems can solve? Where did this miracle? The date of the invention is considered to be the air conditioner in 1902, when an American engineer Willis Carrier created an unprecedented first device to one of New York publishing houses. By design, it really was air conditioning, but his primary goal was not to create a pleasant coolness to employees, and the fight against humidity, which is good compromise print quality. However, as the transformation of the wild capitalism that we are unsuccessfully trying to build today, even air conditioning - and he turned his face to the man. The first tentative steps in this direction have been made only in the mid-twenties, when the air conditioning system has appeared in a department store in Detroit. However, in those years, the air conditioning was a rarity, cost is expensive, and usually designed specifically for the particular building. Direct descendants of these units are the modern central air conditioning system, are still used as a coolant water or brine water.
Types of air conditioners. Differences between the types
Types of air conditioners Ranked Among the domestic air conditioners are two basic types: monoblock air conditioner (window or mobile) and an air conditioner split type system. Window air conditioners - in the recent past, the most common type of air conditioners in our country (series LC). Now almost all foreign companies producing air conditioners offer window models from 1.5 to 5 kW. The simplest of these can only cool air is more expensive - have a heating mode and a remote control. The main disadvantage of window air conditioner is increased (compared with split-system) noise and the need for installation in the window opening. Advantage - low price. Portable air-conditioners - a kind of one-piece air-conditioners. Superficially looks like a small cupboard on wheels. Such conditioners do not require special installation, you only need to take a flexible hose (duct) with a diameter of 15 centimeters and a length of 1-2 meters on the street through the window or hole in the wall. Through this tube is removed the hot air. Lack of mobile air-conditioner - increased noise and high price, comparable to the value of a good split-system. Split-system. This air conditioner consists of indoor and outdoor units, which are connected with electric wire and copper tubes with refrigerant. With this design the most noisy and cumbersome part of the air conditioner compressor is moved outward. Indoor unit can be placed in almost any place home or office. All modern split systems are equipped with remote control (RC) with LCD display.
The climate on the reservation. Review of air conditioning systems
Fashion fitted with air-conditioned cottages came to us recently. Prior to that, it was thought that the climate technology is intended primarily for industrial facilities, shopping and cultural venues, as well as for hotels that accept foreign tourists. Even at the state summer residences of the USSR leaders climatic systems applied only in exceptional cases. Meanwhile in America, and later in the industrialized countries of Europe and Asia conditioning houses has become quite commonplace already in the seventies of last century. In the mansions of the New World were installed window air conditioners and central air-conditioning system-type chiller - fenkoyl and install with variable volume and temperature of air supplied to the premises. In Japan and Korea, and later in other countries are widely used split-and multi-system. Well, with the early eighties from the land of the rising sun on the world market began to arrive, and powerful energy-efficient installation of central air-conditioning comfort type VRV. Today, comfort requirements imposed on the owners of country cottages, meet Western standards. However, most Russians do not have a holistic view of modern air conditioning systems. The right choice for maintaining the ideal comfort in homes cleaned of mineral and organic dust, and deodorized air should contain about 21% oxygen and not more than 0,3% carbon dioxide. Its temperature is between 20-24 ° C, relative humidity - 50-60%, and the mobility of the air mass - 0,1-0,15 m / sec.

Central air conditioning system
Called central air conditioning system serving a few or one large room. Various types of central air conditioners: the type PACKAGED, sectional, self-contained, multizone central air-conditioning. Consider some of them. PACKAGED type air conditioners air conditioning systems such as PACKAGED from the indoor unit cabinet type (sometimes called columns) are used to treat the air in large rooms (concert and conference rooms, shops, restaurants, manufacturing facilities, computer rooms, waiting rooms, ticket halls). By way of feeding the treated air installation of this type are divided into air-conditioning, feeding processed air pressure in the ducts of the ventilation system and air conditioning, feeding processed air directly into the amount of serviced premises. Multizone central air-conditioning in the early 80-ies a number of leading in the field of air conditioning companies (Daikin. HITACHI. Mitsubishi Electric, Mitsubishi Heavy Industries, Matsushita (Panasonic / National), and others) have developed a new product in a comfortable air-conditioning - the so-called system Variable refrigerant flow (VRF), or multizone system successfully combines the advantages of autonomous local and central air conditioning systems. Treatment of air in the room is served by the indoor unit, similar in technical capabilities and consumer qualities of the indoor unit of household or a semi-split systems. Group of indoor units (various types and capacities) is attached to the outdoor unit system of insulated copper piping.
Split systems, multi split systems
Split-system air conditioners These get their name from the English word "split", which means "separate." Split-system consists of two blocks - internal, located in the room, and outdoor imposed on the street. Due to this separation of air conditioning is no longer tied to the window opening, since the indoor unit split systems can accommodate virtually any convenient location. Since the most noisy element - the compressor - passed to an external unit, the noise generated by split-system is much smaller than the window air conditioner. Finally, the significant advantage of a split-system is the ability to pick up this type of indoor unit, which is best suited for a particular room. Indoor units are wall, floor, ceiling, columns and embedded in the ceiling - channel or cluster. The apartments and small office buildings generally use a split system wall type. If you need more cooling capacity 7000 W, using a split-system of other types: indoor complex shape - or duct tape, with glass walls - ceiling, in the halls of restaurants and large halls - a column. It's worth noting that most split-systems, cassette, and channel type allows the penetration of fresh air from the street. Multi-split system if a single external power operates several domestic air-conditioner is called a 'Multi-system. When the number of indoor units is more than six and the maximum distance between the blocks reach the 100 meters, such systems are called multi-zone (zonalnomodulnymi), or VRF-systems.
How to choose the air conditioner?
Air Conditioner - a device which in addition to the traditional cooling air in the room is also used for heating in cold weather, ventilation, drainage, and additional purification of air through the built-in or optional filter is installed. Modern manufacturers offer consumers many varieties and models of air conditioners: from small mobile devices for small rooms to entire systems for large trading floors. The main way to control the temperature in the room - is to install air conditioning. Invented this naipolezneyshaya car was in the early 20 th century in the United States. Father of all air conditioners became the inventor Willis Carrier, who built a refrigeration machine for the printing plant in Brooklyn, New York, though she had intended to fight the humidity. And already in 1924 in Detroit had the first system is for cooling the air in one of the stores. What kind of air-conditioners exist and what is better? 1. Mobile air conditioning - is a conditioner that is installed in the room, bringing a special corrugated hose out the window, door, ventilator or ventilation shaft. Mobile air conditioner takes the air out of the room and divides into two streams: the hot and cold. Hot is removed from the premises through flexible tubing, and the cold stays in the room. Sometimes, mobile air conditioners are equipped with filters, purifying the air of dust, and a built-ionizer. Portable air-conditioners on the market products of companies DELONGHI, King-Post, AIRWELL, ELECTRA, TOSHIBA.
Weather in the house
Anna Bondarenko "are most important - the weather in the house" - sung in the famous song. Let's talk about the climate in a country house. And not in a figurative, but in fact that neither is a true sense of the word. Modern suburban houses are becoming increasingly tight: windows, quality doors, sealing interpanel joints - all this leads to the need for artificially creating the required indoor climate. This problem is not solved through open windows or switching on. Need installation of modern climate control systems. In its most general form can be divided into two large groups. The first - air conditioners (the so-called split systems) which are cooled, dried, heated and filtered air. The second component - the ventilation system to remove moist and polluted air from the room and serve in his stead filtered and heated outdoor air. Adjust the heat most common in country houses were split-system. This is a common name air conditioners, which consist of two separate blocks (split in translation from English - Separate). External unit (condensing unit) is located in front of the building. It can be wall, roof and balcony. Indoor unit (evaporator) is installed in the room itself. He maintains the desired temperature of air, distributes it around the room and runs almost noiselessly. Between the blocks are connected with electric wire and copper tubes in which circulates freon. Since the compressor is outside, in an external unit, the noise level in residential split-systems in the 8-12 times lower than that of air conditioners with combined condensing and evaporator units.

Climatic invention
The next important step in the development of climate technology was the invention in 1961, the first split-system, whose name comes from the English split - split, cleave. Split air-conditioner into two blocks, removing the most bustling street in the unit - the compressor, the first guess in Japan. First came a split system with indoor units of the wall type, but over time have been proposed, and other designs, including split systems with indoor units column, floor, ceiling, tape and duct types. Were created, and air conditioning, in which a single external unit has two or more internal, and therefore became known as' Multi-systems. Taking this direction in Japan have created an alternative to central air conditioning system - VRF-systems that can create comfort once in dozens of areas. Rapidly developing the production of split systems, companies from the country of the Rising Sun began to actively press their U.S. competitors. At present, a split system landslide victory in East and Southeast Asia, Europe and Australia. And here in the Americas, Taiwan, Hong Kong and the Middle East - wherever there is a strong U.S. influence, is still dominated by window air conditioners. In addition, in Europe in the course of local invention - a mobile air-conditioners, which do not require special installation and can move from room to room. The main producer and consumer of these products is Italy. Not stood still and manufacturers of central air conditioning systems, which are widely used to create comfort for large areas and even entire buildings.
