..:: Free Radical ::.. said:If you are considering a long life cycle of the product, several other factors come into play like the bundled warranty, servicing, repair costs, brand presence, resale value and depreciation etc. if you want to be completely 4nal bout it.
..:: Free Radical ::.. said:These are especially pertinent in the Air Conditioner market. Hence, the emphasis by some companies like LG and Samsung on servicing, though they may not make as efficient ACs as Voltas.
..:: Free Radical ::.. said:However, for power consumption purposes, I guess people can make their own judgments from the EER values and the 5year power consumption values the author of the thread has provided.
..:: Free Radical ::.. said:To conclude, in my opinion, this should be a power consumption vs. performance thread and not cost vs. performance thread due to the above variables, some of which can't exactly be quantified.
m4w said:blr_p: Why don't you add a chart which plots prices with EER values. That will be a cost/performance analysis - you can use a scatter chart.
m4w said:And back to the TCO Analysis, what's the hold-up? Let's publish a version now and you can add the hours/city factor in later.
blr_p said:I'm not sure as yet how linear this relationship is, you would think better the EER better the performance, but there can be exceptions TCO wise.
the spreadsheets above use annual compounding.
From what i can gather this whole PV stuff is based on what money you could fetch in the future if you invested it. So, to add costs over a period, future money is discounted to present. Well, no bank i'm aware of offers monthly compunding or annual compunding instead they do quarterly compounding, for domestic deposits.
I also started the hours thread to get an idea of general use, was thinking of 3 bands 3 -6 -10 months annual use etc. that way user selects which band they are in and we can forget city![]()
Table will prolly get done at the week-end by which time more ppl can challenge the approach![]()
