IBM & Carrier in Web-Enabled Air Conditioner Deal

Ggggeo writes "IBM and Carrier Corp. announced Monday that they plan to offer Web-enabled air-conditioners in Europe this summer. Users will be able to control their units through MyAppliance.com and perform such functions as turning units off/on and setting the temperature. The unit will also be able to send errors messages and other diagagnostic info to phones and email addresses. Story at Yahoo! News.

    First, you shouldn't turn your air conditioning off, but instead turn it up (make it warmer) when you leave, then down (make it cooler) when you come home. Otherwise, it takes more energy to cool down a very hot house, rather than a slightly warm house.

    Try it for a month - set your AC to 75 (or whatever is the temp you like), then when you leave the house, up it to 80-85, then back down when you come home. It isn't that bad, doesn't take long to cool down, and your electric bill will be lower.

    What would be better would be room-by-room thermostats that had IR motion detectors, so that you could direct the cooling to specific parts of the house, where you are at, when you are in the area, using vent valves and such, and raise the temperature up and down based on if you are home or not. That would be much better.

    Of course, what I don't understand out here in lovely Phoenix, Arizona, why people don't use solar cooling instead of A/C - it can work great if the house is built properly (read as: proper orientation of windows/walls, having a partially buried house, rammed earth construction, etc)...

      No, another way to think of the thermostat is that rather than running an on/off cycle, it is running at n% power (over sufficiently long periods of time). If you look at the power graphs, it can easily be shown that even for the shortest periods of time, it is better (from an energy usage point of view) to turn the AC off than leave it running if noone is gaining any benefit from it (your animals would qualify :) )

      The electricity company probably wants people to leave their ACs running because they are concerned at the surge when everyone gets home at 6pm and turns on the AC, the TV, brews some coffee and puts on the hot water for a bath.

      Ah, in that case you may want to watch your AC efficiencies. If the one in the back is less efficient, it may end up working harder to compensate for the lack of the front one and in the end, end up costing you more.

      I may sit down and work out the power ratio thing sometime. For example, it may be worth leaving your AC on all day if say it costs you $1 a day more but you're willing to offset that for the comfort value of a cool house. Of course, as I say, the timer fixes that but you have to factor the cost of that in too and then the value of the times when maybe you come home early and it's too hot for you. Then again, in a warmer house, your fridge works harder (unlikely to be enough to offset the cost but a factor nonetheless).

If you are away for two years, is it cheaper to leave the AC running at a slightly higher temperature or just switch it off? If it's true for two years, it's true for 1, it's true for a day or 6 hours.

      I think this fallacy may be linked to the fluorescent light thing where because they use a lot of energy to start up, it is cheaper to leave them on (up to a certain period of time, not permanently) than switch them off. However, this works because the fluorescent light is doing no useful work (producing light) when you switch it on. An AC starts cooling your house as soon as it's running.
