Before you begin installation of a split system, you should be familiar with some of the nuances of such work. By purchasing the appropriate equipment, you will spend a lot, so you should be interested in the question of how to save in the process of operating the system. For example, if thermal contact is maintained between the hot and cold zones, this will contribute to an increase in energy consumption, because the compressor will need to drive heat inside the system, as well as pump the refrigerant.

Garbage and dust inside are not allowed.The vacuum pump is a high-tech device. If there gets a crumb of metal, then it will bring the equipment down. Installation of a split system must be accompanied by ensuring complete tightness. Even if the smallest gaps remain, low-boiling liquids will be ready to evaporate.

The outdoor unit is located below the internal. This will facilitate the work of the compressor, because the thermosiphon effect will work. It is explained by the fact that the heated liquid will rush upward. If you do not take into account this requirement, the compressor will overcome physical forces, and the electricity consumption will again increase. Disassembly-installation of a split system can be done independently. But for this, the outdoor unit must be located in a convenient place. In addition, it should be in the shade. If it is subjected to additional heating, the costs will again fall on the shoulders of the owner.

Installation of the drainage tube is also accompanied by the observance of certain rules. She should not have a bend to the top. If the position of this node is similar to U, then it will cause an infection source, because condensate will be a place for the emergence and development of fungus and microbes, which have spores in the air.

Types and mounting options

Installation of a split system in Azov and other cities can be done. Prices for such works are presented below. But if you plan to do them yourself, then you should know that air conditioners are performed with separate units, one of them will be external, while the other - internal. The latter is an evaporator, but the first is a condenser compressor. These names are conditional, because modern models can cool and heat the room. In the latter case, the refrigerant is condensed inside the unit in the apartment, and evaporates outside. Therefore, allocate indoor and outdoor unit.

Considering expensive models, you should pay attention to the fact that there is a possibility of connecting several internal units to one outdoor unit. Each of them can work separately for heating and cooling. Such a system at high prices at the time of purchase in operation will be more economical, because the heat exchange between the rooms does not interfere, but helps the air conditioner.

Reviews about when to start installation. Opinions home craftsmen about the features of preparation for work

installation of air conditioners split systems

According to the house masters, the installation of a split system is better to coincide with the repair.This is due to the fact that the installation of such equipment is a rather serious task.

For installation, you should prepare:

  • perforator;
  • steel detector;
  • pipe cutter;
  • set for flaring tubes;
  • scraping;
  • hand pump;
  • Vacuum pump;
  • phase indicator;
  • pressure gauge.

Consumers emphasize that a set of bits should be attached to the punch. You will have to make holes in the main wall. Their diameter should be 100 mm. Home masters claim that you will also need a valve detector. If the wall is concrete, then you can get into the bars, so you have to look for a new hole.

Cutting tubes for a coolant is not worth a hacksaw. For this, consumers are advised to purchase or borrow a pipe cutter. If you do not follow this rule, then copper chips will remain in the lumen, it will quickly bring the compressor down.

Flaring the tube with improvised means is also not worth it. To do this, prepare a special set. Otherwise, you will never be able to achieve tightness. A good kit includes a pipe cutter and a scraper. To check the tightness of the system is better to use a bicycle pump. But for the evacuation suitable pump of the same name.
