How Air Conditioning Works Animation--Part 3 of 3 (Heat pump and geothermal)

Animation of compression refrigeration cycle and air conditioning
(See parts 1 and 2 of this sequence for background)
Heat pumps
Ground-source-coupled heat pumps (sometimes called geothermal heat pumps or geo-exchange systems)
Parts 1 and 2 include content on the heat of vaporization, pressure and boiling point, why is an aerosol can cold?, compression refrigeration loop, condensing and evaporating coolant, window air conditioning units, compressors, expansion valves, evaporator coils, and condensing coils, active heating, air distribution and air handling units (AHU), cooling towers, indoor air quality, chiller operation

Energy flows in the path of least resistance. Heat is no different that electricity in this matter... A coil of wire has high resistance values while gaseous/liquid materials do not. Look at your traditional light bulb. It is no different that the element in your toaster. in operation but it is a different material..

Because it is saping the heat from the outside and bring it inside, its "pumping the heat from outside to inside" so you get the electrical wattage of the AC heating the room plus the heat from the outside heating the room effectively making it more than 100% efficient (you get more heat wattage than the electrical wattage you put in)

Yes, but not recommended. Have you ever been outside near your window A/C and felt the heat being blown off the coils? If you turn it around it will put that heat in your home. But you will expose the controls and the electrical circuits to the outside elements. You can buy a window unit that reverses the flow of refrigerant and will apply heat in your home. It is called a heat pump.

Great Video! A question though: How come, energetically speaking, an AC is more efficient in heating a room, than an electrical heat-sink? (coil or resistor of some sort), I am referring to the same heat exchange [Joule/hour]. Where does the energy in the AC cycle, come from? we only "pay" by using the compressor and fans.

Thank you so much for the explanations. Really easy to understand. Excellent job

Many thanks for demystifying the whole aircon process! I sincerely appreciate these videos, fantastic work guys! :D

[Ben Yabets]

Awesome videos! Thank you very much!

You could if you wanted to, though instead the the circulation of refrigerant inside is reversed so that you don't have to keep turning it around. This make life a lot easier and there are no additional parts required. We do usually think of AC's as Air cooling units where they really are air conditioners like their given name.

ikr :D

isnt this kind of like a documentary?
