Split sys­tems got its name from the Eng­lish word ‘split’ — to sep­a­rate, sep­a­rate. Such air con­di­tion­ers con­sist of two types of blocks — inter­nal, which are locat­ed inside the premis­es, and exter­nal, locat­ed on the street. The blocks are inter­con­nect­ed by interblock com­mu­ni­ca­tion: elec­tric cables, heat-insu­lat­ed air ducts and cop­per pipes through which fre­on cir­cu­lates.
Split sys­tems are divid­ed accord­ing to the type of indoor unit into wall, floor and ceil­ing, col­umn and built-in sus­pend­ed ceil­ings — chan­nel and cas­sette. The indoor unit of the air con­di­tion­er can be placed any­where in the office or apart­ment, it is almost silent: the nois­i­est unit of the sys­tem — the com­pres­sor — is locat­ed in the out­door unit.

Where and what kind of split systems are used?

Wall split sys­tems are often used in apart­ments or small offices. If you need to air-con­di­tion a large area, depend­ing on the type and char­ac­ter­is­tics of the room, oth­er types of air con­di­tion­ers are cho­sen: columned split sys­tems are installed in large halls and halls, chan­nel and cas­sette — in large offices with false ceil­ings and in rooms of com­plex shape, floor-to-ceil­ing — in rooms with­out false ceil­ings and in offices with glass par­ti­tions. Sev­er­al indoor units can work simul­ta­ne­ous­ly with one out­door unit — such air con­di­tion­ers are called mul­ti-split sys­tems, they are required when it is nec­es­sary to air-con­di­tion sev­er­al adja­cent rooms. If the dis­tance between the blocks is more than 100 meters, and the num­ber of blocks is more than 6, such sys­tems are called mul­ti-zone, zone-mod­u­lar or VRF sys­tems.
Mod­ern split sys­tems equipped with a remote con­trol and LCD dis­play, with which you can set the tem­per­a­ture with an accu­ra­cy of 1 degree. Most mod­els have a timer for auto­mat­ic on / off and the abil­i­ty to adjust the speed and direc­tion of the air flow. Some air con­di­tion­ers capa­ble of sup­ply­ing fresh air from the street into the room. In the indoor unit, fil­ters can be addi­tion­al­ly installed to clean the air from dust, plant pollen, tobac­co smoke, etc.
