According to the modification, the types of indoor units of air conditioners are divided into:
- Universal;
- Wall-mounted;
- Cassette;
- Ceiling;
- Duct;
- Column.
The dimensions of the indoor unit depend on the type, model, manufacturer and equipment capacity. Low-power household air conditioners take up much less space than semi-industrial or industrial systems.
Wall-mounted indoor units
Cassette
Internal blocks of cassette air conditioners are designed for installation in a false ceiling. Therefore, the dimensions of the indoor units of this type of air conditioners are designed for ease of installation. The height of the air conditioner should be no more than 300 mm.
Some manufacturers create models ideal for installation in suspended ceilings with dimensions of 600x600 mm, that is, with a ceiling cell.
Duct air conditioners
Indoor units of duct-type air conditioners are mounted above the false ceiling. The dimensions of the indoor units of air conditioners depend on the static pressure capacity. Thus, the dimensions of the indoor units of low static pressure duct-type air conditioners are within 800x190x400 mm. High static pressure 1430x500x930 mm.
Column conditioners
This type of indoor unit is not used very often in large public spaces such as museums. The flow of cold air is blown out at about 170 - 180 cm, which is not very comfortable for those, for example, in office premises. Those wishing to buy an indoor unit of a column-type air conditioner will have to pay an amount that significantly exceeds the cost of wall or ceiling units of similar power. The dimensions of the indoor unit of the column air conditioner are on average 550x1800x370 mm.
