The quality of construction and the amount of insulation, or lack of it, is where the good units separate themselves from the mediocre ones. A closed loop of refrigerant absorbs heat and humidity from the interior storage compartments (mostly in the freezer) and passes through a series of coils that draw off and dissipate the heat into the air. With ambient temperatures in the upper 70s and at a temperature setting of 4.5 (1 lowest 7 highest), the refrigerator typically consumes about 30 watts or 2.5 amps DC per hour. Need to power a 5th wheeler at night and air compressor for air tools during day and two deep freezers.

During the construction of our camper, we had the choice of installing either a Dometic CR-1110 Danfoss compressor refrigerator or the standard Dometic three-way absorption refrigerator. This heat starts a chemical reaction and the process of evaporation and condensation causes the refrigerator to cool. According to the Secop website, the maximum current draw of the Danfoss BD35F compressor is 4 amps. Mike, that’s a nice clear explanation of both types of fridges. Most RV manufacturers know this is important, but the word hasn’t gotten out to some RV shops that install these unique refrigerators. If you’re planning to buy a truck camper from the factory, one of the most important decisions you’ll have to make is which type of refrigerator to have installed in it. This compressor is able to accomplish both of these tasks and use far less power than its predecessors, which is why it’s so special. It works through a process called absorption. Top manufacturers include Dometic, Norcold, Vitrifrigo, IsoTherm, and Nova Kool. The Danfoss compressor works in what are called duty cycles, the hourly period when the compressor is actually on and working.

This is why refrigerators that employ vapor compression refrigeration technology typically use a lot of electricity. The source of this heat comes from either a propane flame or from electricity (110 volt AC or 12 volt DC). Take note of amp hour consumption rates and other ratings. Although the Danfoss DC compressor is much more efficient running on 12 volt power than the ammonia absorption type, it still consumes a considerable amount of amperage during a 24 hour day. Having gone through the failures of an absorption unit myself and having to throw food out was such a waste. I would also like to give you a few tips about RV electricity. So if you have some sweet lookin’ pics of your [read more], Truck Camper Adventure is proud to present this interview with Eagle Cap 850 owner, Anne Lewis. An absorption refrigerator is the most efficient when using propane, but less efficient when using electricity. For most domestic fridges, the amperage ranges between 3 and 5 in the case of 120 V. You need a dedicated 15 – 20 amp circuit as the starting amperage is significantly more. Doing this will allow you to monitor the refrigerator’s temperature and will allow you to adjust the temperature setting as needed. For a full-size refrigerator at 90 d temperatures, it uses less than 100 amps per 24 hours. On an average a running refrigerator will need around 2-4 amps.

The power consumption of a gas absorption-style refrigerator versus a residential RV refrigerator are so similar that most RVers say they don’t notice the difference. Has anyone looked at the SunFrost 12-volt system for RVs? Examples: A 120-volt toaster has an amperage draw of 9 amps. If your refrigerator does not surge about 15 amps, you can use a dedicated 15 amp circuit. Looking forward to the compressor in my new-to-me Laredo SC at the end of the month. The Dometic CR-1110 in our camper doesn’t need an external fan to run efficiently in hot weather like the ammonia absorption refrigerators found in our previous RVs. We do not recommend using an absorption refrigerator unless you have RV hookups because the power draw will be enormous. It pays to do some research ahead of time to see if they’re competent installers. Where as the amps drawn by refrigerator when the evaporator fan is the only thing running would be less than 0.5 amps. Can I run a refrigerator on a 15 amp circuit? The refrigerator compressor basically does two things: it raises the pressure of the refrigerant vapor used in the refrigerator and helps to maintain the vapor’s flow rate.
