Which air conditioning

Postby johnincrete » Mon Nov 11, 2019 10:20 am

I have just moved to a new apartment that does not have air conditioning. I am planning for next summer,

What type of aircon is best? Approx. how much to buy and install? Is it likely that any device would be cheaper to but now rather than when it starts to get hot?

I am assuming that, like this year, I would run it for several hours a day.

There is a handy outside wall in both the living area and bedroom.

Thanks

It is worth buying an inverter* type rather than the slightly cheaper non-inverter versions. There isn't a big price difference now.

I have 9,000 Btu versions in each bedroom, which are about 4m x 4m x 2.7m each, and a 24,000 Btu version in the living room, which is 7m x 4m x 2.7m. I could probably have got away with 18,000 Btu in the living room but I had previously had a 12,000 Btu version and that was not sufficient so I wanted to be sure. You can get an idea of prices from e-shop. Obviously fitting would be extra but not that expensive. I think makes like Samsung, Mitsubishi, Toshiba have a good reputation.

In order to fit the ssytem it is necessary to drill a relatively large hole through the wall in order to pass the pipes and cables. This means that you usually cannot fit them immediately above a window since there is often a reinforced concrete lintel there.

* I think people often misunderstand terminology when it comes to air conditioning units. A lot of people seem to think that "inverter" means that it can both heat and cool. That is not the case. I think virtually all air conditioners can both heat and cool.

A standard air conditioner has a compressor that runs at a fixed speed. It controls the temperature by turning the compressor on and off for periods of time. By altering the ratio of the on/off time it can vary the amount of cooling/heating. This is the same way that a central heating boiler works. An inverter type on the other hand adjusts the speed of the compressor to produce more or less cooling/heating. Generally inverter types are more efficient using less energy and therefore cost less to run than conventional types. They tend to achieve the desired temperature more quickly and they maintain that temperature more closely than a conventional type. They cost a bit more because they have more complicated electronics for the DC/AC inverter to drive the compressor while conventional types just have a simpler on/off controller. When comparing different makes look at the efficiency rating.

I'm afraid it is often a balancing act between higher capital outlay/lower running costs or vice-versa together with reliability and longevity. I initially went the low capital outlay/higher running cost route as I didn't know how much I would use them. When I changed the living room unit I went the opposite way with higher capital cost/lower running cost because I found that I use the living room one quite often in the summer but use the bedroom ones much less.

Warwick, I've been looking for a 24,000 BTU AC unit but can't find one. What make is yours please? Where did you buy it? Cheers for info in advance!

I'm surprised you are having trouble finding one as they are quite common. For example e-shop advertise 3. Mine is a Toyotomi and was supplied and fitted by Kreta Therm. They are on the corner of Solomou, which is the continuation of Marko Botsari after it crosses Apokoronou, and Tzanakaki, which runs into the centre with the park on the right. I would have guessed Lavouta on Anagnostou Gogoni would have also been able to supply one plus dozens of other suppliers.

A friend had one installed recently and seemed happy with both the price and the workmanship. I'll ask him tomorrow who supplied it.

Thankyou Warwick. I have now found a few but always like to get personal recommendations especially for fitting. We have a thick stone wall to go through which could be a problem.,

I checked with my friend and he bought a 24,000 unit manufactured by Daikin but I am not sure of the model. It was supplied by Clima Constructions on Kissamou, close to the junction of the Omalos road and the old National Road, telephone 28210 36033 mobile 6972 290038. They also arranged installation and fitting using a sub-contract electrician but with everything paid through Clima. They have other cheaper types available. My friend found that they gave good advice and did not try to push him towards any particular solution. He is pleased with the unit, i.e. quiet and fast to heat/cool the room, and the professional standard of the installation. His was fitted on a normal double brick wall so I cannot advise if the stone wall will cause any problem.

You can go for multi appliance names such as Mitsubishi ect but in the air-con world Daikin is known as one of te better if not the best make.

My friend came to the same conclusion, Frank. He did quite a lot of online research before settling on that make. He previously worked as a Project Director for a major company planning and implementing very large high reliability facilities so he has a lot of experience in selecting equipment.
