Air conditioner thermodynamics

[n00dle]

Hey, sorry if this is slightly off topic but it's the closest forum i could find that might be able to help me answer my question..

A while back i read a page and a little bit of information on it remained behind in my memory. Basically what it stated was 'the simplest form of overunity is an air conditioner/heat pump. overunity is not achieved here by gaining more energy, but by moving it. For example, if 1 kilowatt of electrical power is placed into the compressor, 2 kilowatts of heat will be transferred from plate to plate, due to thermodynamics."

Can someone confirm if this is true, false, or what's the go?

Thanks in advance

This is due the (electric) joule effect.

So this is true? Kickass!
Thanks very much, i will look up the 'joule effect' now for more information.
Thanks again :)

An http://www.houstonairconditioners.net/air_conditioning_replacements.html" is a heat pump. It uses a compressor to `compress a working fluid (usually freon). This compression (work) causes the fluid to heat up. The fluid is then chilled to just above the outdoors ambient temperature using a large fan and cooling surfaces. All of this is done in the outside of your home.
The compressed fluid is then allowed to expand to ambient pressure. This expansion chills the fluid to a COLD temperature. This cold fluid is next passed across coils and fins on the inside of your home. Air is blown across these coils and fins into your house, chilling the home.
The cycle then starts over again by compressing the fluid as it leaves these coils.
As work is performed on the fluid, more heat (energy) is added than is removed by chilling your home. Thus, the outdoor cooling coils must be sized larger to cool the heated fluid than the ones inside your home.

Hi n00dle,

Thank you for your question. I can confirm that the statement you read about air conditioners and heat pumps is generally true.

In thermodynamics, there are several principles at play when it comes to air conditioners and heat pumps. One of these principles is the conservation of energy, which states that energy cannot be created or destroyed, only transferred or converted from one form to another.

In the case of air conditioners and heat pumps, electrical energy is used to power the compressor, which then compresses a refrigerant gas. This compressed gas then moves through the system, absorbing heat from the surrounding air and transferring it to the outside environment. This is why the air being blown out of an air conditioner feels cooler than the air in the room - the heat has been removed from it.

So, in a sense, the air conditioner is not creating more energy, but rather moving it from one place to another. This is why it is considered a form of "overunity" - the output of heat is greater than the input of electrical energy.

However, it is important to note that this process is not 100% efficient. Some energy is lost in the form of heat and friction, so the amount of heat transferred may not exactly match the amount of electrical energy put in. Additionally, the efficiency of an air conditioner or heat pump can vary depending on factors such as temperature, humidity, and the age/condition of the unit.

I hope this helps to clarify the concept of overunity and how it relates to air conditioners and heat pumps. If you have any further questions, please don't hesitate to ask.
