Packless ultra slim condenser & WSHP

Description

The Packless Ultra Slim Condenser & WSHP (Water Source Heat Pump) Coils are specialized versions of their coaxial (tube-in-tube) heat exchangers, optimized for applications where space is extremely limited, such as in residential or tight commercial $\text{HVAC}$ systems.

Here are the key features and technical details:

🌟 Ultra Slim Design and Application

• Space-Saving Profile: These units are designed with the smallest possible diameter and highest flexibility, allowing them to be installed in extremely tight cabinets, chassis, or restricted ceiling spaces where a standard coaxial coil won’t fit.
• Application: They are primarily used as Condensers (heat rejection) or Evaporators/Chillers (heat absorption) in:
  • Residential and Commercial Water Source Heat Pumps [WSHP]
  • Small Water-Cooled Condensing Units.
  • Specific Ground Source Heat Pump designs.
• Ease of Installation: The flexible copper coil structure makes installation and brazing easier within confined enclosures compared to rigid heat exchangers.

🔬 Core Technical Features

The Ultra Slim coils retain the high-efficiency core design common to all Packless coaxial heat exchangers:

• Convoluted Inner Tube: Features Packless’s patented, corrugated inner tube.⁴ This convolution creates high turbulence in both the water and refrigerant circuits, dramatically increasing the surface area and the heat transfer coefficient (⁵$\text{U}$-value).⁶
• Enhanced Heat Transfer: The turbulence ensures that the coil operates with maximum thermal efficiency in a minimal footprint.
• Counterflow Arrangement: Designed for fluid flows in opposite directions, maximizing the mean temperature difference (MTD) and thermal performance.
• Anti-Fouling: The turbulent flow created by the convoluted tube inhibits scaling and fouling on the water side, keeping performance consistent over time.⁷
