        Having grown up in Scandinavia without any air conditioners or even fans, and moving to the US as an adult, I have come to the conclusion that at least part of the reason why Americans are so loud is to be heard over the air conditioning. Many of them are so conditioned (npi) that they're unaware how loud those things are, even the "quiet" ones. When they get someplace quiet, they feel a strong urge to add sound, beca

              Central air can be silent. Small forced air heaters can be noisy. Ridiculous argument is ridiculous.

                Central air can be silent.

                No, it can't. You have to move the air, which causes noise.

                The difference between heating and cooling are many.
                You can easily convert energy into heat, another form of energy. But you can't convert it into cold, which is the lack of energy. You have to generate heat to generate cold -- in fact, more heat than you generate cold, due to entropy.
                Add to this that heat radiates, while cold doesn't. The best you can achieve is not reflecting heat back. So you need to distribute the cold, which takes fans and ducts, and invariably generates noise.

                Unless you have a room with the ceiling consisting of peltier elements, this means moving the cold air from somewhere else to where you want it, and this generates quite a bit of noise. If you're used to 10 dB ambient sound levels when no one is talking, a "silent" central air unit of 30-35 dB sounds rather loud. I know, because I sit in an office with central air right now. Those who are conditioned to the sound won't hear it, but central air is far from silent.
                People here can't hear a mosquito from across the room or their watch ticking on their arm, because it's never silent. In large parts due to air conditioning, including central air.

                  That's not true. An air conditioner is a heat pump, it moves heat from one place to the other, doesn't create it. A heater converts electricity in heat, so it creates heat.

                  • But, as previous poster implied, it typically disspates at least one unit of heat for each unit it moves. Better performance is possible, but worse is more likely.
                    • What?
                    • A heater converts energy from one form to another. i.e. electricity to heat.

                      A cooler is a heat pump - it moves "heat" from one point to another, hotter, point.

                      It is easier to get a high efficiency from a heater because most forms of inefficiency in a system turn out to be “waste” heat – i.e. what you want. Moving heat from one point to another is different. It’s though to get a highly efficient method of moving heat – unless you have demons.

                      What? this thread is crazy. A heat pump will often have a COP for heating as high as 3 and in theory can be as high as 5. That is for 1kW of power i can pump in 3kW of heat (power) into my house. This is without invoking Maxwell demons or any magic. That is Carnot efficiency. I cannot do this with a heat. The COP of a heater is simply 1.

                  False. Well, just about anything causes some noise, but it does not need to be noticeable. Think for a second. Recording studios and TV stations need air conditoining, and have strict limits onthe amount of noise that is tolerable.

          • You should be happy that it was on at all while you weren't in the room. In Japan the whole room - air conditioner, lights, electrical outlets - cut off when you leave, because they are only enabled when your room key is in a slot just inside the door.

            In general, making a few stereotypical assumptions, the air conditioners are probably "undersized" because A) Europeans don't mind a little sweat to conserve energy, and B) Europeans probably have less body fat to cool down.

            A First World country wherein thousands of people die simply because it was hot outside? What's wrong with this picture?

            Perhaps you should ask the people in the Chicago? The difference is that a lot of Europe rarely (or at least it used to be rarely) gets hot enough to require air conditioning in contrast to parts of the US that trace their population growth to the invention of air conditioning due to the stifling heat (at least that's what Atlanta claimed in some of it tourist literature several years ago).

            I would hazard a guess the the main reason for this is that the US is at a lower latitude that much of Europe and lacks the moderating influence of the ocean (no Mediterranean, Rockies block air from Pacific), but I am by no means an expert in such matters. Whatever the cause the US does seem to be, on average, hotter than much of Europe in the summer and colder in the winter. Europe does get hot but not for the prolonged months that the US seems to suffer. This means that not only is air conditioning a lot less common but heat waves occur far less frequently and are typically less severe so, when bad ones do happen, there are far more vulnerable people around because their population has not been reduced by frequent heat waves and there is little/no air conditioning available to help.....of course this does not explain the deaths in Chicago but I'll let you figure out why they happened.

    -- The prior record high temperature at South Pole was recorded on 27 December 1978, not on 12 December 1978, as misquoted in some sources.
    -- Preliminary assessment of  the record high at Nico AWS was -8.2C or 17.2F on 25 December 2011.  This breaks the previous known record of -13.9C or 7F recorded on 4 January 2010.

    First, it's mid summer there. Second, there is no mention of the previous record so we have nothing to compare this "record" to. I have a friend who works there every year and his comments, from camp, last month was that they were battling storms and cold and hadn't been able to get too much work done. Finally, we have only been keeping track of temperatures there since 1956 so it's hardly worth getting into a tizzy over 60 years worth of record data.

    • Second, there is no mention of the previous record so we have nothing to compare this "record" to.

      I guess you did not notice the post made about 20 minutes ahead of yours by gedankenhoren, which compared record high temperatures at two nearby Antarctic stations with their previous record highs:

      -- Preliminary assessment of the record high at Nico AWS was -8.2C or 17.2F on 25 December 2011. This breaks the previous known record of -13.9C or 7F recorded on 4 January 2010.
      -- Preliminary assessment of the record high at Henry AWS was -8.9C or 16F on 25 December 2011. This break the previous known record of -14.5C or 5.9F on 5 January 2010.

      So at these stations (both close to the South Pole), the new record was more than 5.5C above the previous record.

      The previous record is a matter of record: +7.5F in December, 1978. A few summers ago, we had a very warm week and we hit +7.0F in the middle of several days of above-zero temps. While I'm not a Global Warming denier by any means, the specific cause of these record and near-record temps is weather - specifically large masses of warm(er) air coming in from the coast.

      Normally, the weather at Pole is so predictable it follows a simple pie chart hanging up in the Meteorology office - the chart divides the wind direction into dominant categories such that you can look at the reading from the wind vanes and make a pretty good prediction of the present and impending weather (mostly, winds out of Grid North bring in clearer and drier air; winds out of Grid West are warmer and moister; and winds out of Grid South are infrequent and bring unsettled conditions). This is in part because most of the time, the air movement is katabatic, meaning it's rolling downhill, and the terrain around Pole favors winds from Grid North. While thermally-induced winds are not unknown, they aren't the dominant force. It takes a lot of energy to disrupt the usual patterns; that's part of what "Global Warming" means - the entire atmosphere has more (thermal) energy, so there's more available force to create disruptions on a global scale.

        Except you're not speaking of a global weather phenomenon, but a regional one. Further, even in the absence of human induced global warming there will be a lot of thermal energy in the Earth's atmosphere and in the weather of Antarctica in particular.
