Methods ventilation device in a room without windows

Ventilation in a room without windows is an urgent problem, because, if you do not organize automatic air purification, the room will be uncomfortable. It becomes stuffy, it is wet, starts to form fungus, such air elementary harmful to breathe. In order to avoid many problems, You need to consider ventilation system.

How to check if no window space is ventilated?

Most often in houses, especially the multi, builder provides natural ventilation system. It is arranged as follows:: air exchange takes place by vertically extending channels, which extend from the roof of the house to the basement. Special taps unventilated room apartments are connected to the ventilation system. For many reasons, the ventilation in the room may not work.

In order to check the efficiency of the ventilation system, you need to burn rolled in a tube sheet of paper and bring to the grid. Keep it should be at a distance 2 cm, If the paper is pressed against the grate, the ventilation is working properly, and air circulation nothing prevents. If the smoke goes into the room or sheet will not be pressed under the influence of air flow, the drawing is not.

Council: checking, how the system, Do not use an open flame. Newsprint must smoke, but not burn. An open fire can be dangerous, since the carcass exhaust pipe may form flammable and flammable substance different.

The role of systems for air circulation

Ventilation in the room plays a big role with no windows. Even if the room is used infrequently, it collects carbon dioxide. If the room is always more than one person, heat is generated in the amount of 60 W in time, it creates excess moisture, which in the absence of natural or artificial ventilation will settle on the walls. As a result, inside will be very hot, on the walls of the fungus forms, disputes which breathe is dangerous for health.

Clean air ducts can not always provide fresh air flow in the right amount, even if the room has a window. The fact, that deaf plastic products reliably isolate the room. This has positive aspects, but there are also cons, eg, the room is not ventilated itself. With the help of special equipment problem can be solved: the system will be forced to ventilate the room.

Construction of mechanical ventilation

knowing, how to make the ventilation in the room without windows or with blind structures, you can do the work yourself. two fans will need to, having approximately the same power. Besides, You need to purchase a heater and filter; one device will suffice for the system.

To the air where it was taken, punched in the walls for ventilation channels. There are inserted pipe: everything for holes they need to use a hammer.

The diameter of the channels for ventilation

It is not enough to pierce a through hole of any size: we must act, based on the calculation, What’s on 1 m 2 hole diameter should be 1,5 cm; if the room 20 m, You need to punch a hole 20 cm.

DA to ventilation worked well and it does not interfere, positioning hole must be slightly above floor level. On the street duct should go 40 mm. It should be up to direct: This will ensure optimal air intake, the impact of polluted air from the room. In order for the pipe does not enter the trash, it protects the awning and a special grid.

Ventilation in a room without windows is performed in a duct with perforations on the walls, it can be positioned vertically or, either horizontally. You need this device in order, so that the air is distributed evenly in the room. To ensure extract stale air, mounted hood. It is located in the upper part of the wall, approximately at 50 cm from the ceiling, if the house is private, pipe must be raised above the roof to a height of not less than 30 cm. The apartment can put it against the wall at the same height. In both cases the tube should be facing up.

ATentilyatsiya in a room without windows would be more effective, if extract pipe also equipped with a visor by depositing and mesh. It would not let her hide various waste.

In order to efficiently inhale the air into the air duct, you want to use enough power fan. Outdoor air enters the room, previously passed through a filter.

The choice of ready-made solutions

If the bedroom without a window, ventilation may be undeveloped using factory devices, feed fresh air: they are called aerogiverami. Most often, such a device is installed outside the window. The system will not spoil the appearance of the facade, because it has a small size, placed in a special box, whose color can be chosen, outer side closed a practical and attractive appearance bars, through which the air intake.

The average cost of imported aerogivera 25 thousand. rubles. The device is suitable for indoor use, the area of ​​which does not exceed 35 m. Some aerogivery have the function of heating: it is convenient in the winter, because the room will go hot air, It will not feel a draft, the room will not cool. As a result, operation of the system reduces heat loss and save on heating.

Depending on the model and manufacturer aerogivery can operate in different modes: eg, You can set the desired fan speed. More expensive devices show, how the filter is dirty and when it’s time to change it, which greatly facilitates maintenance, avoids loss of productivity and damage. Details of ventilation systems.

Conclusion: If you have a room without a window, ventilation it is necessary. It will make the room comfortable and safe for health. What type of ventilation to choose, It depends on your preferences and financial capabilities of the landlord.

Top 7 Ventless Portable Air Conditioners that Don’t Need a Window

Ben Franklin might fairly be called the father of modern air conditioning! More later on his ground-breaking experiments with cooling through evaporation.

But first, we list and review the best ventless portable air conditioners that don’t need a window – after a few words of explanation we think you’ll find useful.

If you know this information already, please excuse the digress. It might help some readers avoid wasting money on an appliance that isn’t the best choice for their air cooling requirements.

1. These are evaporative coolers. Swamp coolers. Chillers. Evaporative air fans. Evap coolers.

And they can be very effective in the right climate.

2. They are NOT air conditioners in the standard sense of the word.

They do not collect heat indoors and exhaust it outside. That’s what an air conditioner does, whether it is a portable, window, mini split or central air conditioner.

There is no such thing as a portable air conditioner that doesn’t need a window or without a hose. Where would the hot air and humidity go?

Sure, you could connect the exhaust hose to the exhaust fan above your range or the exhaust fan in the bathroom. But…

• There are no models with parts supplied for that.
• Any portable air conditioner could be used that way if you want to DIY the connection.

But that’s not what people mean when they search for portable air conditioners that don’t need a window/hose.

This guide shares accurate information that other sites either (1) don’t understand or (2) fail to communicate with their readers.

Is an Evaporative Cooler Right for Your Climate?

These so-called mini portable air conditioners work by cooling air through evaporation. Think about getting out of a pool or shower into dry air. The moisture on your skin begins to evaporate. It takes heat with it, and your skin feels cool, even chilly.

The short explanation is that swamp coolers work by wetting absorbent material in their interior and pulling hot air over it. As the moisture evaporates out of the hot air, the air is cooled. The fan blows that air your way, and you get relief from the heat. Some of the moisture might contact your skin – and as it evaporates, you get cooler. Simple, effective physics.

What if the air is already humid?

Then a portable air cooler has limited value.

It might be useless – or at least no better (and more of a hassle) than having a fan blow your way. In humid air, adding moisture to the air will make the space more uncomfortable. Again, the humidity is already there. Just point a fan in your direction to produce evaporative cooling of your skin.

This Evaporative Cooler Effectiveness Map accurately shows the best region for their use, where they have limited value and where they are a waste of money.

• Zones A & B – An evaporative cooler will work for you!

The Challenges of Cooling a Room Without Windows

Poorly ventilated rooms have poor air circulation. It makes them hot, damp and even stuffy. Likewise, the humid air inside the room will clog your AC´s condensate drain unit making it overwork, overheat and eventually break down. Ultimately, you incur high maintenance costs that could otherwise be avoided by using a customized cooling unit.

What Size of AC Unit Do I Need?

The size of an AC is usually measured in terms of BTUs. And the size of your model largely depends on the area you are looking to cool with that air conditioner. If you keep this one factor in mind, then you will automatically get better efficiency and lower costs.

If the room is too big, then the AC unit will not cool properly, and if the room is too small, then the AC will cool too soon without properly reducing humidity.

Usually, it is smart to get 20 additional BTUs for every extra sq. ft. in your space.

Review of the Best AC Units For Rooms With No Windows

Often times, rooms that have no windows are also compact in size. This means that whatever the cooling system you are to settle for, it should fit into the available space. And it shouldn’t be noisy and should basically work without the need for constant monitoring.

Fortunately, you do not need to fabricate your own custom-made cooling system. There are already numerous and very efficient hybrid systems designed to operate in poorly ventilated and compact spaces. Here are four such systems to choose from:

Minisplit System

This is a ductless AC designed to sap air from the outside and hence cooling down the room. A mini-split air conditioner is a hybrid structure consisting of a window unit, a central air unit and a condenser. During installation, the condenser is placed outside and then connected to an evaporator placed high up inside the room. The merits of sourcing for a Minisplit system are:

The outdoor components make the system compact enough to fit into small spaces such as small basements and dressing rooms. The indoor evaporator can also be placed in any appropriate point inside the room. Thus it won’t stand in the way of items such as furniture or lighting components.

Since the condenser, which is the noisier part of the system, sits outside the room, the whole system is generally quiet. It makes this cooling system ideal for rooms such as a man cave or a dressing room. Or a relaxation joint where silence is of utmost importance.

The system is flexible and can be zoned so that you only cool individual rooms when the need arises.

Evaporative Air Cooler

If you live in a low-humidity area, the evaporative air coolers can provide a cost-effective way to cool your house. Evaporative air coolers work on the principle of evaporation. By accelerating the natural heat exchange process.

Basically, the system has a pump that draws water from a reservoir and delivers it to cooling pads on the back part of the cooler. Filter pads placed at the back of the system suck in the warm, dry air in the room. And force it to flow over the damp pads causing the water to evaporate. The evaporation cools the hot air thus making your space more hospitable.

Why Install an Evaporative Air Cooler in Your Room

• An evaporative air cooler operates smoothly and quietly. You can thus install it in basically any type of space, be it your dressing area, bedroom, or your favorite relaxation area in the basement.

The whole unit costs much less compared to some other ventilating systems. As it is free standing and doesn’t come with an exhaust vent hose. Compared to some other power-hungry cooling systems, the non-motorized swamp air cooler only needs water to chill your space. This lowers operational and maintenance costs.

Evaporative air coolers are also ventless meaning that you won’t need to alter the room. Or make ugly holes on the walls to vent the system to the outside. This means you can install it with ease and start using it right away.
