Packless ice machine coils utilize a coaxial “tube-in-tube” design. Water flows through the inner tube while refrigerant flows in the annulus between the inner and outer tubes.
The key to the high performance of Packless ice machine coils lies in the convoluted multi-lead inner tube manufactured in a patented process. The resulting convoluted tube has increased heat transfer surface area per unit length, yet still permits full flow of both water and refrigerant around its entire periphery for improved performance. Turbulence imparted by the convolutions to both the water and refrigerant flows further enhances the thermal performance, while inhibiting the accumulation of deposits on the surfaces. The net result is a highly effective, compact heat exchanger with superior anti-fouling characteristics.
Optimum heat transfer with Packless ice machine coils is achieved with a counterflow arrangement of water and refrigerant during condensing.
Packless ice machine coils are covered by one or more of the following U.S. patents: 5409057, 5551504, 5311661.
