In this article I will be teaching you how to make a "Water Chillier"(AKA
"Phaze Change Cooler").
All right now to begin first you must understand how refrigeration works.
The refrigerant will follow this cycle
1: Compressor compresses the refrigerant.
2: The high-pressure refrigerant goes through the condenser where it
becomes a liquid.
3: The liquid passes through a capillary tube to reduce the pressure
4: The refrigerant now evaporates in a low-pressure environment
5: Evaporated refrigerant is suctioned into the compressor
This is a constant looping cycle. The physics behind why this works
are as follows. As you increase the pressure on a gas its boiling point
raises. Meaning once the pressure gets high enough the refrigerant can
become liquid at room temperature now its liquid but it isnt cold.
Now since we
have all this pressure that the freon is liquid but it isnt cold
it will have to evaporate the only way for that to happen is to make
the pressure low enough so that its boiling point drops. This
is done in the capillary tube it provides so much resistance that the
pressure before it can be a few hundred psi, while the other side is
only 10-15 psi. Ok now since the other side of the capillary tube is
only 10-15 psi the refrigerant expands so quickly that it basically
pulls the heat away from the evaporation surface at whatever its boiling
temperature at that psi is.
Now that you know the physics behind why refrigeration works lets get
down to the construction shall we.
