Understanding How RV Fridges Work on Propane

Curious about how your RV fridge operates on propane? Here’s a simplified breakdown for you:

  • Propane Absorption Cycle: RV fridges work differently from traditional refrigerators; they use a propane absorption cycle rather than a compressor.
  • Heat Source: The process begins with a burner that heats an ammonia-based solution in the fridge’s cooling system.
  • Evaporation and Cooling: This heat causes the ammonia to evaporate and cool inside the system.
  • Absorption and Condensation: The ammonia vapor is absorbed by a hydrogen mixture, undergoes a condensation process, and returns to liquid form to repeat the cycle.
  • No Moving Parts: Compared to residential fridges, RV fridges have fewer moving parts, making them more suitable for travel.
  • Energy Efficient: Running on propane, they are energy-efficient and work well for boondocking or when electricity is limited.
  • Versatile: They can operate on various power sources – propane, electricity, or battery – providing flexibility for different travel scenarios.

Remembering these basics will help you appreciate the efficiency and convenience of your RV fridge running on propane.

Checking Propane Levels and Safety Precautions

When running your RV fridge on propane, it’s essential to monitor your propane levels regularly. Keeping an eye on the levels ensures uninterrupted cooling for your perishables.
To check your propane levels:

  • Inspect the propane tank gauge: This visual indicator reveals how much propane is left in your tank.
  • Consider using propane level detectors: These devices offer more accurate readings for peace of mind.
  • Use soapy water to check for leaks: Apply a soapy solution to connection points. If bubbles form, there’s a leak that needs attention.
