One of the first air con­di­tion­ing devices is a win­dow-type device. Pre­vi­ous­ly, they could be seen every­where, hang­ing from the win­dows of apart­ment build­ings. But over time, peo­ple switched to more advanced sys­tems, installing mod­ern devices. How­ev­er, this is not a rea­son to aban­don win­dow air con­di­tion­ers.


Although they are some­what infe­ri­or to oth­ers, such devices can be a con­ve­nient option due to their com­pact size. In addi­tion, their tech­ni­cal equip­ment has also improved sig­nif­i­cant­ly, there­fore, in terms of func­tion­al­i­ty, they are ful­ly con­sis­tent with mod­ern require­ments.

The fresh air win­dow air con­di­tion­er has a sim­ple struc­ture. Every­thing he needs to work is col­lect­ed in one small monoblock. It does not have any detach­able parts that can cause leak­age, and refrig­er­ant charg­ing is done in a work­shop envi­ron­ment. This explains the reli­a­bil­i­ty of such devices, they can work for a long time with­out inter­rup­tion and prac­ti­cal­ly do not require refu­el­ing.

The dis­ad­van­tages of this tech­nique include the fact that it is installed in the win­dow open­ing and reduces the degree of illu­mi­na­tion. If the win­dows them­selves are small, then this can be quite incon­ve­nient. In addi­tion, all monoblock devices are noisy, since their loud­est part is also inside the com­mon box and can­not be tak­en out­side, as is the case with mod­u­lar sys­tems.

It is advis­able to check the noise lev­el of the device while still on the trad­ing floor by turn­ing it on at full pow­er. Although man­u­fac­tur­ers are mak­ing var­i­ous attempts to reduce the num­ber of sounds, the devices still remain quite noisy due to the oper­a­tion of the com­pres­sor and fans.

At the air con­di­tion­er, there are lou­vers on the duct open­ing that direct the air flow. Their posi­tion can be adjust­ed man­u­al­ly, set­ting the flow up or down, depend­ing on whether the device is work­ing for cool­ing or heat­ing. For more mod­ern mod­els, it is also pos­si­ble to adjust the posi­tion in dif­fer­ent direc­tions, and this hap­pens auto­mat­i­cal­ly, using a small motor.

Principle of operation

A win­dow air con­di­tion­er with air sup­ply from the street can work for cool­ing, as well as per­form the func­tion of a con­ven­tion­al fan. Some mod­els also heat the air, but they can do this if the tem­per­a­ture out­side is not low­er than ‑3 degrees, oth­er­wise the device will break.

The prin­ci­ple of oper­a­tion of this type of equip­ment is also asso­ci­at­ed with the cir­cu­la­tion of the coolant in the sys­tem. The pres­sure is gen­er­at­ed by a com­pres­sor. The air is pumped into the unit, where it gives off heat to the cool­er, and then enters the room. The win­dow flow-through air con­di­tion­er does not have any spe­cial unique nuances; its cool­ing prin­ci­ple is the same as that of oth­er split sys­tems. The dif­fer­ence is only in the design and tech­ni­cal para­me­ters — pow­er, avail­able func­tions.

Installation steps

A win­dow air con­di­tion­er with out­door air can be installed by fol­low­ing the instruc­tions that are usu­al­ly includ­ed with the appli­ances when they are pur­chased. As a rule, there is all the infor­ma­tion in Russ­ian, as well as dia­grams with a visu­al demon­stra­tion, so dur­ing the instal­la­tion process it is quite pos­si­ble to under­stand:

  • The eas­i­est way is to install the device in a reg­u­lar win­dow, with­out dou­ble-glazed win­dows. First you need to pre­pare a hole where the body of the device will be placed. You also need to care­ful­ly choose a place so that the air con­di­tion­er is pro­tect­ed from rain or snow.
  • It is not nec­es­sary to install the device close to the ceil­ing, the min­i­mum dis­tance should be 20 cm. Also, from the out­side, any obsta­cles to air intake should be exclud­ed — bill­boards or decor ele­ments.
  • To prop­er­ly drain the con­den­sate, you need to install the air con­di­tion­er so that the out­er edge is slight­ly low­er than the inner one, by about 10 cm.
  • After instal­la­tion, it is nec­es­sary to process the hole with seal­ing foam so that there are no gaps left.
  • If the device is not too pow­er­ful, then it can be plugged into a reg­u­lar out­let, but for devices that con­sume a lot of ener­gy, you will need to make sep­a­rate wiring from the switch­board. In this case, you need to resort to the help of an elec­tri­cian or take care of this issue your­self, if you have the nec­es­sary skills.

Tip: to pro­tect the out­side of the air con­di­tion­er from var­i­ous atmos­pher­ic phe­nom­e­na, you can put a plas­tic or met­al visor over it. This ele­ment is not includ­ed in the kit, but it is easy to make it your­self. This can extend the life of your air con­di­tion­er.

Modern models

Oa horse-mount­ed air con­di­tion­er as a sup­ply ven­ti­la­tion does its job well, so it can be pur­chased if for some rea­son it is not pos­si­ble to install a con­ven­tion­al split sys­tem. Man­u­fac­tur­ers con­tin­ue to pro­duce mod­els of this type, so it is easy to find a mod­ern device that has all the nec­es­sary func­tions:

  • Gen­er­al Cli­mate offers the GCW-09HRN1 mod­el equipped with var­i­ous fea­tures. This device can work for heat­ing, it has a timer, auto­mat­ic mode and remote con­trol. The price is 12–15 thou­sand rubles.
  • LG releas­es the W07LC. It can only work for cool­ing, and also ven­ti­lates the room, there is an installed antibac­te­r­i­al fil­ter. Man­age­ment is man­u­al. The cost is quite afford­able — 10 thou­sand rubles.
  • Sam­sung has AW07NOC mod­el, can cool and ven­ti­late. There is a night mode and an antibac­te­r­i­al fil­ter. The device costs 9 thou­sand rubles.

Even well-known man­u­fac­tur­ers pro­duce quite afford­able mod­els that buy­ers with a lim­it­ed bud­get can afford, so there is no need to go through the assort­ment for a long time, look­ing for var­i­ous ana­logues. This is one of the advan­tages of such air con­di­tion­ers — they are cheap­er than split sys­tems, which allows you to save a lot. How­ev­er, with all the right fea­tures, a win­dow air con­di­tion­er will do an excel­lent job of cool­ing the room.
