  • love the video really good

  • Much better description than the "howstuffworks" site which would have completely confused me If I didn't already understand how an A/C system works. Kudos!

  • New Inverter type Mini-Split heat pumps will keep your home warm down to about 5 degrees F, depending on the model.

    My Sanyo Mini-split (also called a Ductless) cools all summer and heats all winter.

    Only on really cold days (under 8 deg F or -13C) do we have to turn on some back-up heat.

    Paying 21 cents per kWh, & using about 10 kWh per day (during cold weather) is less than 1/4 the cost of heating with oil.

  • much better use of energy than a fireplace, i know fireplaces are cozy but they also have a low effectiveness and are very bad for people with asthma and other respiratory problems.

  • very well done

  • I have the same picture on my mantle! Different frame though.

  • cute video.

  • couldn't have made it clearer really :)

  • I love this video , oh and I have something to ask you can I send you a message i want to download this album in downloadmusic .im

  • Heat pumps suck if you live in an area that gets under 30 degrees in the winter and that's a fact.

  • @prostreetcamaro Who wants to swim when it is 30 degrees F or -1 degrees Celsius...

  • thanks so much

  • is there a reason there use an expansion valve instead of something like a little turbine to harness the energy of the moment from high pressure to low, or is it just to make the mechanism simpler?

  • @skittlesmonkey the expansion valve is a restriction in the system that enables you to have a high pressure/tempreture side and a low pressure/tempreture side in the system!

  • @skittlesmonkey Well the amount of energy reclaimed from such a turbine would be very small and it is not cost effective to put one in. The expansion valve is much cheaper and there are less moving parts to break or wear so it is also more reliable.

  • @skittlesmonkey the expansion valve is an isenthalpic expansion, which means that the working fluid maintains its enthalpy energy. if you had a turbine the working fluid would lose its enthalpy

  • Yes!

  • thanks for sharing! grazieee

  • Awsome!!!!
