Glycol-Based Thermal Backup Cooling System – DescriptionDefinition:
A Glycol Thermal Backup System uses a chilled glycol solution (a water and glycol mixture) to maintain cooling in cold storage rooms when the primary refrigeration system fails or power is lost. How it Works:

• Glycol (commonly propylene glycol or ethylene glycol) is a liquid that resists freezing and can retain cold temperatures for a long time.
• The glycol solution is chilled to a very low temperature during normal operations.
• When power fails:
  • The cold glycol continues to circulate (either naturally or via battery-powered pumps).
  • The glycol absorbs heat from the cold room, keeping the temperature low without active refrigeration.

Main Components:

• Glycol Storage Tank: Stores chilled glycol solution.
• Glycol Cooling Coils or Plates: Installed inside the cold room walls, floor, or ceiling.
• Temperature Sensors: Monitor the internal temperature.
• Control Panel: Automatically switches to glycol backup mode when power fails.
• Battery Backup Pump (optional): To circulate glycol if natural convection is not enough.

Advantages:

• Non-toxic and food-safe (if using Propylene Glycol).
• Long cooling duration depending on the tank size and initial temperature.
• Simple system, low maintenance compared to compressed gas systems.
• No need for pressurized gas handling (safer than CO₂).
• Can be designed for both short-term and long-term backups.

Typical Applications:

• Cold rooms for fruits, vegetables, dairy, pharmaceuticals.
• Ice cream storage rooms.
• Any cold storage where moderate backup time is needed.

Important Notes:

• Glycol concentration must be properly set (usually 30% to 40% glycol mixed with water).
• If the mixture is too dilute, it may freeze.
• If using battery pumps, battery maintenance is important.

In Short:Glycol-based backup systems offer a safe, reliable, and efficient thermal backup solution for
