1. Electrolux EACS/I‑09HM/N3_15Y

A well-known invert­er mod­el released by the Swedish Elec­trolux back in 2016. The wall split sys­tem is capa­ble of work­ing both for cool­ing and for heat­ing the area. By the way, the man­u­fac­tur­er rec­om­mends using this air con­di­tion­er in rooms up to 25 sq. m, oth­er­wise, the pow­er of the sys­tem may not be enough to main­tain the desired tem­per­a­ture. When choos­ing, pay atten­tion to the fact that the indoor unit of the split sys­tem is rel­a­tive­ly qui­et, but the out­door unit is quite noisy. EACS/I‑09HM/N3_15Y has a deodor­iz­ing fil­ter and forced ven­ti­la­tion mode. True, in the lat­ter case, the split sys­tem can­not cool or heat the air.

2. Toshiba RAS-09U2KHS-EE / RAS-09U2AHS-EE

A fair­ly pop­u­lar invert­er split sys­tem from man­u­fac­tur­ers of cli­mate equip­ment Toshi­ba. Despite the rel­a­tive­ly afford­able price, the “Japan­ese” has a rea­son­able min­i­mum of fea­tures. The wall mount­ed sys­tem can han­dle air cool­ing or heat­ing in an area of ​​25 square meters. m. True, there may be prob­lems with heat — the man­u­fac­tur­er does not rec­om­mend using the air con­di­tion­er in heat­ing mode at tem­per­a­tures below ‑7 ° C. The rest of the options are fair­ly stan­dard: anti-icing sys­tem, set­ting mem­o­ry and ven­ti­la­tion mode. This split sys­tem is quite noisy and at peak pow­er lev­els it can emit a hum of 40 dB. And some users com­plain about a notice­able vibra­tion, but appar­ent­ly this is a fea­ture of indi­vid­ual instances.

Pros and cons

Mod­el from a well-known Japan­ese brand, high-qual­i­ty assem­bly

Noisy, works for heat­ing up to ‑7°С

3. Carrier 42QHC009D8SA

Invert­er split sys­tem with wide func­tion­al­i­ty. Pow­er in cool­ing mode is 2700 watts, and when heat­ing it reach­es 2900 watts. Car­ri­er 42QHC009D8SA has a spe­cial “Max­i­mum Pow­er” mode to quick­ly reach a com­fort­able tem­per­a­ture. Of course, since this mod­el is invert­er, the sys­tem smooth­ly reg­u­lates the speed of the com­pres­sor motor, which sig­nif­i­cant­ly saves ener­gy. So, Car­ri­er 42QHC009D8SA con­sumes only 780–820 watts. By the way, you should not wor­ry about the reli­a­bil­i­ty of the invert­er mech­a­nism in this air con­di­tion­er — the man­u­fac­tur­er gives a 3‑year war­ran­ty. This mod­el is able to effec­tive­ly main­tain the air tem­per­a­ture in a room with an area of ​​25–29 square meters. m. Air con­di­tion­ers are adapt­ed for Russ­ian win­ter con­di­tions and are guar­an­teed to work up to ‑15 ° C out­side the win­dow, which is very valu­able when heat­ing has not yet been giv­en or has already been turned off. The Car­ri­er 42QHC009D8SA is also very qui­et, emit­ting only 21 dB of sound in sleep mode.

4. Mitsubishi Heavy Industries SRK20ZSPR‑S / SRC20ZSPR‑S

Anoth­er “Japan­ese”, but not at a demo­c­ra­t­ic price. Mit­subishi has a con­ser­v­a­tive design, so if you like the “clas­sics” of the late 90s and ear­ly 00s, then out­ward­ly you will like this split sys­tem. But the fill­ing here is mod­ern — an invert­er, auto­mat­ic tem­per­a­ture main­te­nance and a sys­tem against the for­ma­tion of ice. The con­di­tion­er can pro­vide heat­ing of the room at ambi­ent air tem­per­a­ture to ‑20 °C. Accord­ing to the man­u­fac­tur­er, the area for effec­tive main­te­nance of the micro­cli­mate is 20 square meters. m. This invert­er mod­el is one of the nois­i­est on the mar­ket, more­over, not only the exter­nal, but also the inter­nal unit is “loud”, so you should not put this air con­di­tion­er in the bed­room. And for some rea­son, Mit­subishi was greedy and did not equip the back­light con­trol pan­el.

Pros and cons

5. LG P07SP

Wall-mount­ed invert­er split sys­tem with inter­est­ing “chips”. The LG P07SP uses a Dual Invert­er com­pres­sor which pro­vides reduced vibra­tion and pow­er con­sump­tion. By the way, about the lat­ter, the air con­di­tion­er con­sumes only 650 watts at peak pow­er val­ues. The max­i­mum noise lev­el is only 33 dB. But there is also a big minus — the heat­ing should be turned on when the air tem­per­a­ture out­side the win­dow is not low­er than ‑5 ° С. A cru­el joke with the mod­el was played by the man­u­fac­tur­er’s desire to uni­fy the remote con­trol with more advanced mod­els, because of which sev­er­al but­tons on it sim­ply do not work, which some users took as a hoax.

Split sys­tems for one room

How to max­i­mize com­fort in a small space

How to choose an inverter split system

The com­pres­sor in clas­sic air con­di­tion­ers runs until the room tem­per­a­ture reach­es the set tem­per­a­ture, and then turns off. When the tem­per­a­ture ris­es above the desired lev­el again, the com­pres­sor starts. Sequen­tial switch­ing on and off leads to the fact that the tem­per­a­ture in the room fluc­tu­ates by 2–3 ° C.

The com­pres­sor of the invert­er air con­di­tion­er runs con­tin­u­ous­ly, chang­ing its per­for­mance in the range of 30–100%. This reduces ener­gy con­sump­tion, increas­es the life of the com­pres­sor and the entire sys­tem, and avoids tem­per­a­ture fluc­tu­a­tions. On aver­age, invert­er air con­di­tion­ers are qui­eter than clas­sic split sys­tems (on-off). We will tell you what to look for when buy­ing an invert­er split sys­tem.

Cooling capacity

One of the main para­me­ters of the air con­di­tion­er is the cool­ing capac­i­ty. The high­er it is, the larg­er the area of ​​the room can be cooled by the device. This is a key indi­ca­tor when choos­ing air con­di­tion­ers. On aver­age, for every 10 sq. m of area is con­sid­ered to be the norm of 1000 watts. Buy­ing a device of low­er pow­er will not live up to expec­ta­tions: the device will not cope. And over­pay­ing for an air con­di­tion­er with much more pow­er is inap­pro­pri­ate.

Price and maintenance cost

Invert­er air con­di­tion­ers are on aver­age more expen­sive than clas­sic mod­els. But the start­ing price of the pur­chase is off­set by sav­ings in the bud­get for elec­tric­i­ty and sys­tem main­te­nance in the future. Invert­er mod­els last much longer than on-off mod­els.

heating function

Air con­di­tion­ing can be not only a sal­va­tion in the hot sea­son, but also become an addi­tion­al source of heat in the off-sea­son or cool weath­er in sum­mer. Here we can note one more advan­tage of invert­er mod­els: such air con­di­tion­ers can be used for heat­ing even in severe frosts. Clas­sic mod­els can work for heat­ing at tem­per­a­tures up to ‑7 ~ ‑10 ° C out­side the win­dow, and invert­er mod­els up to ‑15 ~ ‑20 ° C. Heat­ing with an air con­di­tion­er con­sumes 3.5–4 times less than heat­ing with oth­er heat­ing devices. In addi­tion, the warm flow can be direct­ed to a spe­cif­ic area, with radi­a­tors and con­vec­tors this will not work.

Air Filtration and Treatment

In advanced mod­els, in addi­tion to the usu­al coarse fil­ter, a clean­ing sys­tem for unpleas­ant odors, bac­te­ria and virus­es can be pro­vid­ed. The built-in ion­iz­er in some air con­di­tion­ers helps to sig­nif­i­cant­ly improve air qual­i­ty.

Noise and vibration

Low noise lev­el will ensure com­fort even when the device is run­ning. It is espe­cial­ly impor­tant to con­sid­er this char­ac­ter­is­tic when plac­ing the air con­di­tion­er in the bed­room or nurs­ery. The noise lev­el of the indoor unit aver­ages 22–25 deci­bels, while advanced mod­els have 19–22 deci­bels. The noise lev­el of the out­door unit should be paid spe­cial atten­tion to those who place the unit on an open bal­cony, ter­race or take care of the com­fort of neigh­bors when the out­door unit is mount­ed at their win­dow.
