What is the air conditioning is better to choose an apartment for rating

Very often plagued by the summer heat to residents of houses and apartments, no less than the winter cold.However, if the heating system has always been considered in our region an indispensable element of any property, then the maintenance of optimal cool has, until recently, at the household level has not been given much attention.Air conditioning is only seen as objects of some special luxury, and the prevailing view was that without them it is possible to do.

However, the situation is changing, and a growing number of home owners prefer to spend a certain amount in order to establish yourself and your family the most comfortable conditions.Air conditioners have become a very running and extremely popular type of goods, and their range may initially even confound inexperienced in these matters consumer.This means that many will be useful information: how best to choose a conditioner for the apartment Rating of popular models, evaluation criteria and the choice of what issues need to focus?

In short - you need to evaluate when choosing a conditioner

to begin with, consider the list of issues that are to be answered in order to select the optimum air conditioner model for apartment:

• necessary to determine just what constructive scheme will best meet the existing operating conditions - floor, window or split-system.
• most important parameter of HVAC equipment is its cardinality opportunities.
• Features planned operation - whether the equipment will be used only for air cooling or heating is required and the function.
• should take into account the energy efficiency of the device - depends on the efficiency of its operation
• important is the degree of noise equipment.
• to choose between the model of the conventional type or inverter.
• Considerable importance have additional functions, such as filtering and "recovery" of conditioned air.
• consumer must decide whether to additional automated equipment options are needed.
• And finally, when choosing such an expensive equipment is extremely important to its classification and rating of the manufacturer.

Consider the basic air conditioner selection criteria in more detail.

Variety of household air conditioners

So the first thing is to start - is to decide what type of air conditioner has to be purchased.All models can be divided into two large groups - a monobloc apparatus and a split system consisting of two or more blocks.These groups also have their own division into types, the main criterion which has become especially the air conditioner installation.

Monoblock conditioners

By monobloc air conditioners include window and mobiles.

• Window air conditioners yet not so long ago completely dominated in this area.At the same time, they do not enjoy great popularity, since shortcomings in this scheme is much more than the advantages.

The advantages of window air conditioners can be attributed to their relatively low cost.Another "plus" it is that such devices do not require complicated installation - just install them into the prepared opening and turn on the power.

But the creation of such an aperture can become a serious problem.You have to either compromise the integrity of the window, or cut an opening in the wall - both require the already complex construction operations.In the present widespread plastic windows with double-glazed windows features self-installation is even less - have to order a special window design configuration that will necessarily affect its value.

After installing window air conditioner will need to seal the gaps between the body and the prepared opening - too bother.Finally, the work of air conditioning - quite noisy, as the compressor unit is in the same monoblock.

This air conditioner will be more appropriate for temporary summer family residence in a country house.At the end of the season it is easy to remove and take away for the winter, and the opening at this time, close the shield.

• Mobile monoblock floor execution also have their advantages, but again will not be the best option for housing conditions.

Their mobility, by the way - is also very conditional.This air conditioner will still be "bound" to have done a channel that connects to the flexible corrugated hose for hot air output into the street.You can, of course, to arrange such a conclusion, and in the half-open window, but it started to treat it as a regular method of conditioning the apartment - not too wisely.In addition, such devices - enough headroom and massive, in and of themselves, and even in combination with corrugated stretching - severely cluttering the room.Plus the noise factor of the action - the compressor is placed directly in the room.Another caveat - the need to monitor the accumulation of condensation to prevent overflow collection tank.

a word - it is also a great option for temporary summer residence conditions - such a device is easy to take with you to the countryside and set in any room where air conditioning is required.But for a city apartment such a solution still can not be called the best.

Split systems

Split - system characterized in that it consists of at least two blocks.One of them, the outer comprising substantially all of the force component, ie, compressor and cooling system, passed on the street.In the room there is only a block (one or more) direct cooling air and its distribution over the volume of the room, with a monitoring and control system.Now it is clear that the most noisy system modules located outside.

indoor units may have different performance and purpose:

• In a domestic environment the most commonly used wall blocks.They have, as a rule, horizontal arrangement, an elongated rectangular shape, with one or another of the chassis - you can pick up optimally suitable for existing or planned interior space.

• for apartments large area, you can choose multi-split system, when one outdoor unit "tied" two, and sometimes - and more internal.

Interestingly, each of the indoor units can have their own personal settings.Buying a multi-split system, of course, expensive, and installing it with the seal of extended communication - is not easy, but still it is more profitable than the purchase, installation and operation of two or three separate sets of equipment.

• for suspended ceilings are well suited indoor unit cassette type .It is very unobtrusive in the modern interior, and most importantly, is able to distribute the conditioned air flows in all directions.

Typically, the size of these indoor units adapted to the standard dimensions of the elements suspended coffered ceiling of type "Armstrong" - 600 × 600 mm.

• An interesting feature of the indoor units are , wall, ceiling type .Their design provides the ability to vary the placement method.

This unit can be mounted on the wall near the floor, the type of heating convector - air flow in this case is directed along the wall.Another option - the unit is mounted horizontally on the ceiling with the direction of flow of chilled air along its surface.

• In a domestic environment the normal use of the apartment is practically not found, but still noteworthy system and column channel type.

Internal power channel-type systems located discreetly, and laid him ducts for supplying conditioned air to different areas of one large room or in different rooms of the house.

Indoor Unit column type installed in the premises of a large area to distribute the cool air uniformly as possible throughout.

Both type of split systems have increased rates of labor power, and they are commonly used for air-conditioning large halls, commercial space, offices, production facilities, etc.However, the channel-type air conditioner can be installed in a private home, with seal airway communications on all premises.

But in a city apartment such complexity installation is hardly justified.

summarize the advantages and disadvantages of split-systems:

By advantages include:

• power split systems are usually significantly higher than that of single-block models.
• whole "power" part is located outside the premises, thus achieving low noise level during operation of the equipment.
• There is a choice of indoor unit on a method for placing and external decoration.
• Permanently installed unit does not require much space, it fits well into the interior.

disadvantages of a split system can be considered as follows:

• installation complexity.Not only must securely fasten the outer and inner blocks, but also to connect them with electric cables and pipes for the refrigerant.Such work requires a skilled approach, and most owners will not be available for self-fulfillment.

Installation of domestic air-conditioner - not an easy task!

Algorithm installation works depends on the type of equipment.Get acquainted with the technical advice, in order to evaluate your ability to self-installing air conditioning , it can be in a special publication of our portal.

• second conditional "minus" - once the system is fixed, and does not imply any "seasonal journeys."In principle, of course, you can also dismantle it and re-install, but it will be tantamount to a new installation with all the attendant costs.
• And finally, do not forget about the particular vulnerability of the external unit, a little protected from vandalism manifestations, for example, on the first - the second or on the upper floors.There is one caveat: the order of the local authorities may be prohibited from placing blocks on the external facade of the building - it should also be borne in mind.

However, for installation in a modern apartment in the first place should be guided precisely to the split-system - the benefits it has still much more.

How to choose the air conditioner performance of its power are in power

calculation of the required power of the system

One of the defining parameters of HVAC equipment selection.And in this case the question is not about the power consumption and heat engineering on - on the ability of the device to cool a certain room.

you have to perform certain calculations.

Cooling the air conditioner power is expressed by the following relationship:

Qp = Qv + Qm + Qt

Qr - the calculated cooling capacity;

Qv - the power required to cool the room a certain volume and the level of insolation (Incoming sunlight);

Qm - power to compensate for the heat generated by the people in the room.

Qt - power to compensate for the heat from the appliances.

Qv calculated as the product of volume of the room to the insolation factor (power density per unit volume):

Qv = V × q

How to calculate the volume of the room - you know, probably all - the area is multiplied by the height of the ceiling.A q factor shall be equal to:

Features premises	The coefficient q
North and north-east - the sun never gets in the window.	30 W / m³
Moderate sun exposure - east, west or north-west side.	35 W / m³
Intense sun exposure - the southern, south-eastern and south-western side, a large area of ​​glazing east or west sides.	40 W / m³

In any case, when using the air conditioner it is necessary to provide a barrier on the path of direct sunlight, at least in the form of semi-transparent curtains or blinds.

Qm - the heat generated by people.One person in a calm state produces about 100 watts, 130 watts - for mild activity and up to 150 watts - during intensive physical activity.For the residential air-conditioning system, as a rule, it is enough to the first value.It suffices to multiply the number of people who are normally in this room.

Qt - the amount of heat generated is constantly working appliances, may be taken as:

type of home appliances	approximate amount of heat
stationary computer	300W
TV	200W
Other household Appliances and Lighting	30% of the rated power input

total value of all these values ​​and show the necessary power conditioner.Usually the range is chosen with a lower limit - 5% to + 15% of the top.

Qr - 5% & lt;Q range & lt; Qr + 15%

algorithm is valid for residential area of ​​small and medium stated above.In the calculations of HVAC equipment for large areas are used more complex calculations.

Effect of air flow to the calculated power conditioner

Another important nuance.In the above calculation does not take into account the inflow of air from the outside, that is, it is true for conditions with the windows closed.If necessary ventilation (and as it happens in practice), the air entering the room from the outside and falls additional amount of heat, especially in hot weather.
