The Advantages & Disadvantages of Split Wine Cellar Cooling Systems vs. Ductless Mini Split Systems

Ductless “Mini Split” Wine Cellar Cooling Systems

Examples: Wine Zone, Vigilant, Cellar Mate

Advantages

  • Sleek evaporator design

Disadvantages

  • Cannot be covered to match décor
  • Must be wired to the condensing unit which is the only power supply option
  • Nearly all manufacturers are 230V with no other option
  • Most operate on R22 refrigerant. It is not ideal to use at these temperatures for performance or efficiency. It is likely to be phased out soon like dozens of other refrigerants have been. When it is
  • More difficult to install
    • Explanation: Ductless Mini Split Systems use a fan coil originally designed for air conditioning. LG, Sanyo, Mitsubishi, Fujitsu, Trane and many other companies make great equipment for air conditioning. These systems are designed to operate in the 68°f to 78° f range efficiently and assist in removing humidity from the air for a more comfortable living space. To modify these units to the much colder temperatures needed for wine storage a crankcase pressure regulator is added. These systems are then forced to run at pressures and temperatures they are not actually designed for. If there is any variance of pressure in that valve it can cause the following issues
      • Overload the compressor causing drastically shorter life or catastrophic failure
      • Ice up the fan coil causing severe spikes and drops in room temperature or catastrophic failure
