re: The home / office air-conditioner thread Navin, the window units do have a smallish vent that sucks in air from the rear chamber, however it is not necessarily clean air as it's clarity depends on the cleanliness of the rear chamber itself. If you can have it cleaned regularly then yes window would be a better option.
Coming to the splits the problem is with their water pans wherein the condensed water collects before draining off. Over time muck does accumulate and this gives rise to the growth of mold, fungus etc. Now the commonly used splits are called high wall mounts and their design does not allow for these drain pans to be removed and cleaned. In lieu of this the other type of split called as the Ceiling wall split is designed in a way that lets the drain pan to be removed and cleaned out. This type of IDU can also be floor mounted to aid with the ease of cleaning. These IDUs are not usually available off the shelf or in dealer stock but are definitely available against order.
Regarding the change of air, well our rooms are not air tight and the air change will happen albeit slowly. If it is allowed then opening the windows at certain times will be the best bet. Ionizer is a good idea but as a stand alone unit and not coupled with the air con, this is my personal view.
The General window units are better in terms of performance but you will find it noisier than the Hitachi TM that you have. Here is some info regarding General splits w.r.t. filtration. Click and read under "technical superiority" :: ETA GENERAL :: Quote:

We already have 2 2T Hitachi Window (Twin Turbo) ACs in the other bedrooms. We are looking for an aircon with good filteration so that our son's allergies are not aggravated by dust. Room size is about 230 sq.ft.
Is there a better option? How would O General compare? |
The remotes on my Hitachi Atom and Mitsubishi splits have self glowing buttons. Not all but basic ones like on/off, temp up/down & mode. I think Panasonic has this too as do some models from Daikin's Ururu Sarara range. Quote:

Take a look at Whirlpool's machines. At least you will get a Japanese compressor also the condenser & evaporator are of much better quality than a lot of the 'phoren' brands. Quote:

Why this kolaveri kolaveri
The problems arise when manufacturers start using IDU panels made locally. The finishing at the moment is as yet miles behind compared to what is coming out of the South and Far East Asia. The other issue is with the parts made from thermocol. These tend to break very easily as the locally made thermocol does not have enough density and is quite fragile. Once broken or cracked there are no replacements available. On the mechanical side the components are pretty good, compressors are the same but the again the electrical/electronic components have varying quality levels. Quote:

That is not entirely true as is exemplified in your very next statement
What is absolutely true is that some people still want the reciprocating compressors and I am one of them. The only other acceptable designs for me are scroll ( mostly found from 3 tons & up) and the swing design (offered by Daikin). Quote:

Still their earliest compressors were reciprocating types and now they have shifted to rotary ones which are more energy efficient but even now there are people who still want the reciprocating types. I am not sure about the 1 ton rating as M5 has quoted, but I think their 1.5 T window unit may be 3 star. | |
