Vent Free Evaporative Air Coolers

If you want to keep cool without running an expensive portable air conditioner, get an economical ventless evaporative (swamp) cooler and save money now on running costs. If you just found this page, you’re in for some interesting reading, as this is the focus of this website.

Staying cool in hot weather indoors is not just a convenience, it’s a necessity in certain climates!

In Search of Affordable Cooling

In the past, the only effective way to chill the interior atmosphere to make it comfortable enough to live in was to employ a power hungry heating, ventilation and air conditioning (HVAC) monster. It cost a fortune to operate but provided the much needed respite from the searing heat outside.

Ordinary fans are OK but they only push hot air around the room, they don’t actually chill it in any way. You feel cooler in the breeze they create because the moving air evaporates the sweat on your skin, creating a drop in temperature as the sweat is evaporated.

Swamp coolers work in a similar way, with the big difference that they pass moving air through a moist membrane, evaporating the moisture. That creates cold air that really does reduce the ambient temperature in a room; in some cases by as much as 30 degrees!

The amazing thing about this type of air cooling solution is that it does it extremely cheaply when compared to regular air conditioners, either portable or fixed installations. The running costs are so much lower thanks to there being no motorized air chilling, compressor refrigerant system (and the power needed to run it) as with regular aircon.

And the other big attraction of swamp coolers is there’s no need to vent to the outside!

So here we have an extremely economical, highly portable and ventless air cooling solution that is powerful, quiet to run and environmentally friendly. As long as you have low humidity levels where you live or work, you can enjoy the benefits of this type of climate control solution for those months of the year that get really hot and you need to be comfortable!

There are many different models from several different manufacturers, so when faced with a choice it can get tough to know which will suit your individual circumstances the best.

My top pick for 2016 is the Honeywell CS10XE pictured right. It’s a low cost model to buy (you can get one online from Amazon today by clicking the image), super economical to run and still has a high output that can cool a room of up to 175 sq ft by 25 degrees or more.

It’s 21 pint tank is big enough to keep the unit running for several hours before needing a refill. Yet its light enough to make it extremely portable and easy to wheel around from room to room.

Remember, this amazing cooler does NOT need an exhaust hose to vent hot air because it doesn’t produce any hot air. It’s exactly what you wanted when you found this page!

In fact, that’s where this site can really help you. I have included several individual product reviews as well as comparison articles so you can see which model has the best benefits you’re most interested in.

Add to that the kind of power output you will need and then average costs for purchase and running. There is a lot here but that’s exactly what you need to make an informed decision on which is the best one for you.

By way of a spoiler, I’m also listing my next three top swamp cooler models that are best for general use in regular size rooms or outdoors. You can click the image of the cooler you like best if you want to visit the page where you can buy it:

Free Standing Air Conditioner Without Vent Hose?

Despite what you have already read here, you may be surprised to know that there are many people that will ask, “Can you really have such a device that will keep you cool but doesn’t need a ventilation hose to vent hot exhaust air to the outside of the house?”

ac with no vent hoseAnd if those people had been reading this page, their question would already have been answered! But even so, it can be a little difficult to really understand this if they’ve been accustomed to using a regular aircon device that did have an exhaust vent.

Let’s talk about this a little. You already know that in order for a refrigeration device (which is essentially what a portable aircon unit is) to produce chilled output, it must generate a similar amount of heated output from the heat exchange process. You can’t have one without the other!

That heated output cannot be allowed to disperse in the room you want to occupy or it will increase the temperature, not reduce it–which is your aim. So it must be forced outside of the room (preferably outside of the building altogether) and that’s what the exhaust vent is for.

That flexible corrugated plastic pipe is a nuisance at best because it has to be fitted to an installed outlet in the wall or as is more often the case, dangled out a convenient slightly open window. The latter case is not ideal as some of the heat will re-enter the room through that window opening, but the net effect is a cooler room so the occupant is happy enough with the system.

Evaporative Air Cooler vs Air Conditioner

Then you have the alternative in the free standing evaporative or swamp cooler that does away with the need for a refrigeration heat exchange process altogether and relies on nature’s own temperature control process: cooling by evaporation. This simplified process means there is no heat exchange and therefore no heated output from the device, only cold output as long as the humidity level in the room is sufficiently low (below 50% is optimum).

Where conditions are ideal (and you want to compare evap cooler vs air conditioner), the truth is that a swamp cooler can perform equally well when competing against an AC unit while doing so using considerably less power. In fact, the only real power usage is that of the fan and some ancillary power for the timer and any other “controls” that may be featured on the unit. The typical power usage is often below 100 watts of electricity.

Compare this to the considerable power requirements of an AC compressor and heat exchange engine which runs into the kilowatts range and you can quickly see how much more economical the swamp cooler is when set up against a comparable AC in terms of temperature chilling capacity. The purchase cost is another factor that sways heavily in favor of the lower energy consuming device, with comparable units costing well over half that of their more power hungry alternatives.

If It Absolutely Must Be a Portable Air Conditioner

I quite understand that there are a lot of people living in areas that have high humidity and simply cannot take advantage of the low energy evap cooler to keep them comfortable during summer’s hot, sticky weather. In this situation, a free standing AC unit is probably the only way to beat the heat effectively. If making do with a vent trailing out a suitable window means getting through the summer in relative comfort, then so be it!

So as not to leave such a large percentage of the population wondering which free standing air conditioner is best for them, I’ve included these models which are highly rated and big sellers at online stores such as Amazon this year. Take a look for yourself by clicking the image or link below it:

Note: The three AC units above must be vented to the outside via a flexible exhaust duct supplied with the unit. These examples have been included for those who live in climates with high summer humidity levels where swamp (evaporating) models will not work as effectively.

There are many very good reasons to opt for a low power, high output climate cooling evaporative device over a regular portable or fixed AC or HVAC system as long as the local climate will sustain it with low enough humidity levels during the hot season to make it viable.

If cost, environmental factors and sheer portability are benefits that fit with your own ethos, then this is the choice you should be making to keep you and your family cool during the hot summer months.
