Invert­er split sys­tems, out­ward­ly, do not dif­fer from ordi­nary wall-mount­ed air con­di­tion­ers, except for stick­ers. In fact, there are car­di­nal dif­fer­ences, but they are all inside.

Many peo­ple ask the ques­tion, what does an invert­er split sys­tem mean? This con­cept comes from the Latin con­cept “inver­to”, which means to turn over, change. It was the change that formed the prin­ci­ple of oper­a­tion of such com­pres­sors, which can oper­ate at a vari­able speed. Thanks to this, the air con­di­tion­er has become more eco­nom­i­cal. In addi­tion, such a split sys­tem can oper­ate at sub-zero out­door tem­per­a­tures.


Inverter system: principle of operation and features of the device

The prin­ci­ple of oper­a­tion of the invert­er split sys­tem is to reg­u­late the oper­a­tion of the com­pres­sor depend­ing on the air tem­per­a­ture in the room. When the set air para­me­ters are reached, the com­pres­sor does not turn off, but con­tin­ues to work, main­tain­ing the tem­per­a­ture of the air mix­ture.

Thanks to these fea­tures, less noise is gen­er­at­ed and the life of the com­pres­sor is sig­nif­i­cant­ly increased, as there are few­er starts. Run­ning by itself wears it out quite a lot. The thing is that after the com­pres­sor stops, the oil in it to lubri­cate the rub­bing parts flows into the crankcase, and when start­ing, the com­pres­sor works for some time in “extreme” con­di­tions.

The principle of operation of the inverter type systemThe main device of a split-sys­tem with invert­er con­trol is a com­pres­sor. Most often it is called the “heart of the air con­di­tion­er.” Thanks to him, fre­on is com­pressed. In addi­tion, thanks to the com­pres­sor, gas moves along a closed pipeline pipeline. But with­out oth­er devices, the oper­a­tion of the air con­di­tion­er is also impos­si­ble.

  1. Evap­o­ra­tor. It is in it that the tran­si­tion of fre­on from a liq­uid state to a gaseous form occurs. In this case, the tem­per­a­ture of the heat exchang­er itself decreas­es, and, accord­ing­ly, the ambi­ent air. The evap­o­ra­tor is locat­ed in the indoor unit of the split sys­tem.
  2. Capac­i­tor. In this device, the reverse process of tran­si­tion from the gaseous state of fre­on to its liq­uid form takes place. Dur­ing con­den­sa­tion, the gas gives off heat to the out­door air mass­es.
  3. Throt­tle, or as it is also called — a throt­tling device. It is designed to sharply com­press fre­on in front of the evap­o­ra­tor. This device is locat­ed in the indoor unit of the air con­di­tion­er.
  4. Fans. As a rule, there are two of them, one is locat­ed in the exter­nal, and the sec­ond in the inter­nal block of the split sys­tem. They are designed to cre­ate air cur­rents that blow over the evap­o­ra­tor and con­denser.

There are also invert­er-type mul­ti-split sys­tems. Their main dif­fer­ence from con­ven­tion­al air con­di­tion­ers is the pres­ence of sev­er­al indoor units. They are designed to cre­ate com­fort­able con­di­tions in sev­er­al rooms at once. Depend­ing on the type of mul­ti split sys­tem, it can work per­fect­ly with two, three, and even sev­en indoor units.

Advantages and disadvantages

Like any cli­mate tech­nol­o­gy, such sys­tems have their unde­ni­able advan­tages, but also some dis­ad­van­tages that will be con­sid­ered. Advan­tages:Photo: Saving electricity is one of the main benefits

  1. More accu­rate tem­per­a­ture main­te­nance with­in the spec­i­fied lim­its, com­pared to con­ven­tion­al air con­di­tion­ing.
  2. Low­er noise lev­el com­pared to clas­si­cal type air con­di­tion­ers.
  3. They cool the room much faster, since from the moment of start-up until reach­ing the set tem­per­a­ture regime they work at full capac­i­ty.
  4. It is much more eco­nom­i­cal than its clas­sic “com­pa­tri­ots”, due to the absence of peak loads dur­ing com­pres­sor starts.
  5. They have a longer ser­vice life. This is due to few­er com­pres­sor on/off times.
  6. Can work at rather low out­side air tem­per­a­ture.

The dis­ad­van­tages include their high cost, com­pared with clas­sic air con­di­tion­ers. In addi­tion, they are very sen­si­tive to volt­age surges, so if there is such a prob­lem in the home, care must be tak­en to install devices that smooth out pow­er surges.

When Should You Buy Inverter Air Conditioning Systems?

There are sev­er­al main rea­sons why peo­ple choose such cli­mate tech­nol­o­gy for them­selves.

  • How not to get lost among the variety of presented systems?One of the main rea­sons for pur­chas­ing such equip­ment is their increased ser­vice life. The abun­dance of brands, and var­i­ous fakes con­fuse most buy­ers when choos­ing. And since the split sys­tem is already not cheap, many peo­ple pre­fer to over­pay for an invert­er about 50% of the nor­mal cost of an air con­di­tion­er, for its reli­a­bil­i­ty and dura­bil­i­ty.
  • The sec­ond rea­son for the pur­chase was the econ­o­my. It is known that invert­er cli­mate tech­nol­o­gy con­sumes less elec­tric­i­ty.
  • This type of air con­di­tion­er has a sig­nif­i­cant reduc­tion in noise lev­els.
    The pur­chase of such sys­tems should be con­sid­ered by those who are plan­ning rede­vel­op­ment in their home, in con­nec­tion with which, the heat load may increase.

Invert­er cli­mate con­trol tech­nol­o­gy is quite expen­sive. It cer­tain­ly has its advan­tages and dis­ad­van­tages. In some cas­es, such an air con­di­tion­er is sim­ply nec­es­sary, and in some it is a waste of mon­ey, so take their pur­chase and instal­la­tion seri­ous­ly.
