Because the compressor cycles on at frequent intervals, a constant source of power must be available. Find the perfect fit for your refrigerator. How can we use this handy bit of physics to shift It is attached to a timer and thermostat that work to regulate the temperature and cycling of the defrost heater and compressor ( … The left-hand side of the picture shows For someone who travels part-time and/or who usually connects to shore power at campgrounds and RV parks, the type of setup we have would not be necessary. We should repeat for the sake of clarity here that a 12V RV refrigerator doesn’t require as much power as a residential refrigerator thanks to the elimination of the need for an inverter and the greater efficiency of the strictly 12V fridge, but you’ll still need an ample battery/solar setup if you plan to be off-grid for long periods. The decision must factor in the unique needs of the RVer making the choice. Not true! This site uses Akismet to reduce spam. We could, however, move a decent amount of heat by letting a gas expand and contract much more so it converts into a liquid and back again—in other words by changing it into a different state of matter.

This is a somewhat inefficient use of power, an admission we make while also acknowledging that this is what we do for the luxury of having a large residential refrigerator. The vacuum from the compressor sucks the cold gas back around, and the cycle repeats as long as the compressor is running. The compressor will run longer under warm conditions. what's happening inside the chiller cabinet (where you keep your food). This means you either need to be plugged into shore power, run your generator, or have sufficient battery power to run the fridge using your inverter. This is essentially how refrigerators move heat from their cooling cabinet to the room outside. If the compressor and fans are operating normally but not running often enough or long enough to maintain the correct temperatures in the fresh food and freezer sections, then the cold control may be defective or out of calibration. Pros of 120V Residential Refrigerators in RVs, Cons of 120V Residential Refrigerators in RVs.
