This is an efficient and compact tubular or "tube-in-tube" structure. Heat exchanger used as condenser or evaporator.
Depending on the operating conditions, the outer tube is made of steel or copper, and the inner spiral tube is made of copper or copper-nickel. situation.
How does it work?
These devices direct water flow through the inner tube and refrigerant flows between the annular space of the inner and outer tubes. The refrigerant and fluid are at different temperatures, meaning heat is transferred from higher to lower temperatures in a countercurrent fashion, and the spiral inner tube creates turbulence between the two fluids. This helps increase the heat transfer surface area.
Features and Benefits
