Portable Air Con

[dibble1]

I've just bought a rather pricey portable air conditioning unit, (on castors) as I live in a mobile home & it gets a bit warm. It works really well and doesn't need ice like some similar do, my rather drawn out question is, how does it work? You just connect a hose to it, the same as a tumble drier which you put out of the window, switch it on & bingo! I'm well chuffed but rather mystified.
Many thanks for reading!

It is like a free standing refrigerator. As it cools the air, the water in the air will condense out and collect in a reservoir , you must empty the reservoir regularly or water will start to leak out onto your floor .
That's about all you need worry about. They can sometimes 'ice up' and you need to turn them off to 'defrost' them as you do with a fridge.

In a nutshell it's a fridge in reverse. Instead of removing the heat from the air inside the fridge and having a radiator at the back to let the heat escape into the kitchen, the A/C unit removes the heat from the air in the room and has a radiator on the inside - the hot air is blown out of the tube to the outside world.

There's nothing to empty. Air enters the unit, some of it is chilled, same method as a refrigerator or chiller, and is blown out the front. The extracted heat is transferred to the rest of the air which is blown out the exhaust tube and the back. The tube needs to be pointing outside.

Not all portable air con units need emptying, some have a system to evaporate the condensate in the exhaust.

With regard to how they work, they compress a gas which makes it very cold, then move that gas through a coil. They then force the air in the room over that coil to cool it. The problem is that the compressor itself produces heat, but at least that is easy to manage and is pushed out of the room. As mentioned on another thread, if you have a single-hose system, the slight drawback is that air will be pulled into the room to replace that which is pushed out.

Mine doesn't.

A correct decision. When I worked in the office, I had to buy a similar air conditioner. It was also on wheels from the company Panasonic. The office was small. I was starting my business then, and I rented a small office for work. But I didn't have enough heat, although it was influential in terms of parameters. My friend work from company https://www.socool.sg/. He suggested to me that it is better to connect a hose to it. Just like you did. It helped me a lot. A couple of years have passed, this air conditioner still serves me.
