The Two Main Types Of Air-con Units And How Their Mechanisms Differ

With hotter weather, our thoughts often turn to creating a more comfy environment in which to live

, play and work. Perhaps you just remember the hot, sticky and sleep-deprived nights you endured last summer and related to oneself "that is it, no more living in an oven!". Whatever led you to this call isn't that vital, but now you've got some other calls to make.

For instance, will you go for an absolutely channeled system for you home or merely a room air conditioner to make the hot nights more acceptable? Or maybe you might go for a split system, where you have got an out of doors unit attached to an inside unit by 2 refrigerant lines. These are all options if you have your house, but what if you are hiring? Many owners wouldn't be content for you to make adjustments to their building without agreeing to leave the whole installation for the following renter. Inversely , you would clearly not be glad to pay for an installation that you can only use for a set time.

The solution to this issue is the use of a portable air conditioner. This article will focus on this type of unit. So, what are your options in portable air conditioners? Well, basically there are two types of units; evaporative and refrigerated. Let's have a look at the differences.

Evaporative units use the theory of passing air over water. If you were going to run a fan in a room, you would simply be blowing hot air round the room. This moving air would cool you down slightly due to it taking away the heat from your skin surface, but the effect isn't heavy in extraordinary conditions. You'll still feel hot and awfully uncomfortable. If one was to blow the air thru a wet fabric, the water would absorb some of the heat from the air and vaporize. Hence , the air that comes out the opposite side would be cooler. This is largely how an evaporative unit operates. A pump moves water from a reservoir tank over a pad ( wet fabric ) and a fan blows air thru the pad.

It is a fairly simple idea. There are but some flaws. The 1st one is performance. You'll only drop the temperature by 1 or 2 degrees at the very best. You can improve this a little by employing ice with the water. The other negative is that the humidity will obviously increase, which can generally make the room feel 'sticky '. Also, you're going to need to top up the tank now and again. The benefits are the price and portability. You can buy one of those units for a little less than $100 and there aren't any special installation wants. Just fill with water, plug the power in and go.

Cooled units look similar, but are quite different in their operation. They also depend on evaporation, but it is evaporation of a refrigerant contained inside a high pressure closed system. The system comprises a compressor to pump the refrigerant round the system, an evaporator, which work like a vehicle radiator and the interconnecting pipe work. The refrigerant leaves the compressor at high pressure and is taken to the evaporator, which faces the interior of your home. The refrigerant is permitted to expand in the evaporator, and in doing hence will drop it's temperature. This cooler refrigerant is permitted to pass through a coil. Air from the room is blown over the coil and the heat from the air is soaked up by the refrigerant to be returned to the compressor, through a compressor coil. Another fan passes air over the compressor coil to cool down the heated refrigerant and expel it to the outside air. In a transportable unit, this is channeled outside through a window kit.

So, in short, if you don't mind paying a little bit more, the refrigerated unit will provide much greater performance over the evaporative one. The only downside is that it is heavier and will use a bit more power. Whichever unit you choose, it will be make life in your home more enjoyable as you won't feel like you're slowly melting away into the summer months.
