If you feel like you're being picked on or something, I apologize, that's not my intent. I'm trying to provide you information to help you learn. I think you're fundamentally not understanding how these things work. For example, you said:

>reflect 99.99% of light on the condenser unit

The radiator - what I assume you meant - is emitting only a very tiny fraction of the overall heat as IR. Most of that heat is being transferred to the air via vibrations. This is because electrons much MUCH prefer to share their energy by bumping into things than by emitting light.

Let's take a step back.

"Temperature" is a measure of the total motion of the particles in an atom, especially the electrons where the vast majority of the motion is happening. So when we talk about "heat" and "temperature" what we really mean is "how much energy the electrons have."

Quantum mechanics gets it's name because electrons can't absorb just any energy. They have to absorb specific amounts of energy. When we talk about the energy that an electron can absorb as being non-continuous (IE. not any amount, only specific amounts) we refer to this is "quantizing." We are quantizing the amount of energy an electron can absorb, and saying that any quantities not of these specific quantities won't be absorbed.

That's where quantum mechanics gets it's name.

Photons are modeled in our system of physics two ways. One is as a particle called a photon. This is a fixed quantity of energy, a quantized amount of energy. The other method is as a wave, which has a wavelength and frequency. A photon is both a particle and a wave, it has properties of both. The wavelength (which is inversely proportional to the frequency) defines the amount of energy the photon has. The two are directly related and you can't have a photon of different energy but the same wavelength. If it's wavelength is x, it's energy is y - ALWAYS.

For an electron to absorb a photon, the photon has to be of one of the specific wavelengths it wants to absorb (it has to be the correct quantized amount of energy).

Once absorbed, the electron has 2 ways of getting rid of it:

1. Emit it back out - same energy released, same wavelength.
2. Vibrationally relax - bump into nearby electrons, give them some of the energy they absorbed.

Once 2 happens, the electron can no longer emit that same wavelength of light - it doesn't have that energy anymore. It can emit a longer wavelength of light (less energy), but it gave some of the energy to another electron, so it can't emit the same energy it absorbed.

For reasons I won't get into, electrons overwhelmingly prefer option 2. Option 2 is faster, it's less "violent" to the electron, it makes everything easier.

Option 1 only happens in extreme circumstances - usually when option 1 isn't available after a relatively long wait (think nanoseconds for option 2, and 1-2 seconds for option 1).

This is why a radiator won't emit IR radiation of a wavelength matching it's temperature. It'd much rather just bump into the air and warm the air up. And this is why heat pumps can warm your home, versus just shooting a bunch of IR light around while you're freezing.

You have to find a way to take that radiator, get it to emit IR light, and get that IR light to be of a frequency that will pass through the atmosphere (probably using some kind of stimulation to increase the frequency).

But that's not all you have to do. You then have to emit that light very specifically away from the Earth (if it just emits everywhere - not in a straight line like a laser - it'll hit trees and the ground and water and just get absorbed again).

This is a technologically monumental task, and one that is going to require massive amounts of energy (almost certainly more than you can emit in the laser).
