Please pay attention that all air conditioners (except canal and some cassette devices) cool and heat the air indoors without supplying with fresh air from outdoors. If you want to change it, purchase a special aeration system.
 Split system is an air conditioner, which consists of two units (indoor and outdoor). Now such air conditioners are the most popular as domestic devices. As a compressor is built in an outdoor unit and moved up outdoor, the noise level is very low. All modern split systems have a standard consumer functions collection. Another split-system’s advantage is large selection of indoor units, which can be wall, floor, ceiling, column and built-in a false-floor - cassette and canal ones.
Split systems benefits are the following:
- quietness;
- ergonomic design;
- full collection of functions;
- an opportunity to install the system in almost any place.
Disadvantages include:
- professional assembling necessity;
- high cost;
- fresh airflow absence.
