Kako deluje razvlaževalec?

Če se sprašujete, kako se najbolje spopasti z zatirajočo vlago, ki jo doživljamo na ameriškem jugu, ste morda zastavili vprašanje:"Kako deluje razvlaževalec?"

Kot morda že veste, je vročina v tem delu države le en vir nelagodja. Drugo je vlaga. Razvlaževalec, če je pravilno nameščen in nastavljen, lahko odpravi odvečno vlago in vam pomaga, da se počutite udobno v zaprtih prostorih.

Toda o čem govorijo razvlaževalniki zraka? In zakaj so tako uporabni v tem podnebnem pasu? V tem članku bomo poskušali odgovoriti na vsa vaša vprašanja o razvlaževalcih zraka, vključno s tem, katere vrste so najbolj smiselne za vaš dom.

Kaj sploh je razvlaževalec?

Dobro vprašanje! Začnimo z osnovami. Razvlaževalec je naprava, namenjena zniževanju vlažnosti v zaprtih prostorih.

Če vaš dom trpi zaradi visoke vlažnosti - pogosta težava zlasti na jugu - lahko nastavite razvlaževalec, da zniža relativno vlažnost (RH) v prostoru na želeni prag. V mnogih domovih se RH giblje med 65 % in 80 % od pomladi do jeseni. Z razvlaževalcem zraka lahko RH znižate na veliko udobnejših 50 % do 55 %.

V bistvu je razvlaževalec naprava, ki je zasnovana za uravnavanje vlažnosti, ki presega to, kar zmore klimatska naprava vašega doma.

Kako razvlaževalec zmanjša vlažnost?

Ko razvlaževalec deluje, se postopek odstranjevanja vlage odvija na naslednji način:

• Ventilator v razvlaževalniku dovaja zrak v enoto
• Znotraj razvlaževalnika se vlaga v zraku pretvori v kondenzacijo na zunanji strani notranje tuljave s hladilnim sredstvom v njej; to je zelo podobno delovanju klimatske naprave.
• Zrak zapusti razvlaževalec z manj vlage, kot jo je imel, ko je vstopil v enoto
• Vlažen zrak v vašem domu postopoma nadomesti bolj suh zrak, ki zapusti razvlaževalec
• Kondenzat, ki nastane v razvlaževalniku, odteka v posodo ali, če imate enoto za celotno hišo, v odtočni vod ali cev, ki ga odvaja iz vaše hiše

Ali moja klimatska naprava tega že ne počne?

Da in ne. Vaša klimatska naprava je zasnovana za dve stvari:nižjo temperaturo in nižjo vlažnost. V najbolj vročih dneh v letu, ko je veliko delovno, bo običajno precej dobro poskrbelo, da bo zrak v vašem domu ostal suh in udoben. Dlje kot deluje klimatska naprava, več vlage bo odstranila.

Toda klimatske naprave so konfigurirane na termostat . Zato se tipični AC odziva samo na spremembe temperature. Dejstvo, da odstranjuje tudi vlago, je zgolj naključno.

Tukaj je primer. Če klimatsko napravo nastavite na 73 stopinj, bo iz vašega doma odstranil toploto in vlago, dokler notranja temperatura ne pade na 73. Klimatskemu sistemu ne morete povedati, kakšen odstotek relativne vlažnosti želite, zato lahko zniža vlažnost na udobna raven ... ali ne.

On the hottest days of the year, the AC in this example will run for long cycles. It might lower your humidity to 55% RH, which is great. But on warm-but-not-scorching days, it won't run as frequently. It will always get your temperature down to 73 degrees, but it might only get your RH down to 70%. That's still a pretty high level!

Basically, your AC will only remove humidity to the extent you keep it running. During the fall when it's 75 degrees outside and with 80% humidity, there's a good chance you'll be uncomfortable indoors.

Well, unless you've got a dehumidifier.

What kind of dehumidifier should I get?

For most homeowners, the choice will be between two different types of dehumidifiers:

• Standalone portable dehumidifiers
• Whole-house dehumidifiers

Standalone portable dehumidifiers

Standalone units are great for certain situations. If you just need to manage humidity in one room, they're a good buy. You'll see them in offices, waiting rooms, and so forth.

However, these small dehumidifiers also have drawbacks. In addition to having a limited coverage area, most will only dehumidify until the onboard tank is full of water. If you're not around to manually empty the tank and reinstall it, the humidity will quickly creep back up to an uncomfortable level.

Do some standalone dehumidifiers have a drainage option? ja But you'd have to run a drain line out from your living room or wherever you put the unit. Most people don't want a PVC pipe or drainage hose running through their living space. What's more, standalone units typically only have 1-year warranties and really aren't designed to be serviced.

Whole-house dehumidifiers

Whole-house units don't have the problems described above. They connect to your central HVAC system's existing ductwork and drain all of the condensate into a pipe. Aside from changing the air filter periodically (usually twice per year) and having them serviced annually, they're basically a set-it-and-forget it device!

A whole-house dehumidifier also has a much better parts warranty, a great labor warranty if it's installed by a conscientious HVAC company, and — this part's great — you never have to see it! Unlike a standalone unit that lives inside your house, makes noise, and generates a lot of heat inside your home, a whole-house unit is quiet, out of sight, and distributes the heat it produces across your ductwork so it's not directly heating your living space.

The downsides of whole-house dehumidifiers? Well, they cost more than portable units, which is to be expected. But you also have to be sure that you receive a proper whole-house dehumidifier installation. In some cases, people will have an HVAC company install their dehumidifier only to be disappointed in its performance. More often than not, this isn't because of the unit itself. It's because of how it was installed.

At PV, we follow very specific installation procedures for dehumidifiers. Because of how we install them, you can feel confident that they'll keep your humidity at a comfortable level all year round!
