Charging lithium batteries for your air conditioner?


This is our favorite new device. We do not sell it but we highly recommend it. Check it out and determine if it is right for your vehicle. Buck-Boost DC-DC Converter 25A / 50A / 100A DC-DC Converter for charging a 12/24V service battery in vehicles with an intelligent dynamo. The 50A Buck-Boost DC-DC Converter is a DC-DC converter for charging a 12/24V service battery in vehicles with an intelligent dynamo. Since, when the engine is running, these dynamos (powered by the on-board electronics of Euro 5 and 6 engines) do not always emit the correct charging current, a DC-DC converter is essential for charging the service battery properly. https://www.victronenergy.com/dc-dc-converters/buck-boost-dc-dc-converter-25a-50a




Choosing the right wire size for your new air conditioner?


Using the correct wire for your new air conditioner is important! Use the chart below to determine the correct wire size for your application. Always use stranded insulated copper wire rather than solid strand wire for possitive and negative connections. *If installing in a traditional recreational vehicle you cannot connect to existing houshold wires. *When in doubt use the next largest wire size. *Typically 2AWG is standard or 2x 4AWG if space is limited.




Correct Air Conditioner Sizing?


The ability of an air conditioner to cool a vehicle or maintain a desired temperature is dependent on the heat gain of the vehicle. Physical size of vehicle Window area Quality and amount of insulation Exposure to sunlight Number of people inside the vehicle. Outside temperature As a general rule, discharge air will be 15- 20 degrees F or 8 - 12 degrees C cooler than the air entering the unit. For example, if the air entering the air conditioner is 80 degrees F or 27 degrees C (return air), the supply air (discharge air) into the vehicle will be 60 to 65 degrees F. or 15 to 19 degrees C. As long as this temperature difference is 15 to 20 degrees F, or 8 to 12 degrees C is being maintained, the unit is operating properly. Again, give careful consideration to the vehicle heat gain variables. During extreme outdoor temperatures, the heat gain of the vehicle may be reduced by: 􏰀 Parking the vehicle in a shaded area 􏰀Keeping windows and doors closed Using window shades (blinds and/or curtains) 􏰀 Avoiding the use of heat producing appliances. 􏰀 For a more permanent solution to high heat gain situations, additional vehicle insulation, window awnings and/or window glass tinting should be considered.




Roof Requirements


A 14-1/4′′ x 14-1/4′′ (±1/2′′) square opening is required for installing this unit. Roof construction with rafters/joists support frames on a minimum of 16 inch centers. Minimum of 2 inches and maximum of 5-1/2 inches distance between roof to ceiling of RV.




Choosing Proper Location For Unit


When determining your cooling requirements, the following should be considered: Size of RV. Window area (increases heat gain). Amount of insulation in walls and roof. Geographical location where the RV will be used. Personal comfort level required. For one unit installation: The unit should be mounted slightly forward of center (front to back) and centered from side to side. For two unit installations: Install one unit 1/3 and one unit 2/3’s from front of RV and centered from side to side.




Frost On Cooling Coil?


Frost on a small portion of the cooling coil is not unusual. Under certain conditions, ice may form on the evaporator coil. This is indicated by very cold output at very low air speed and the icing can be seen through the air inlet hole with the filter removed. If this should occur make sure air vents are open and not obstructed. AC units have a greater tendency to frost when the outside temperature is relatively low. This may be prevented by adjusting the thermostat to a warmer setting. Should frosting continue, operate unit on FAN ONLY setting until the cooling coil is free of frost; then resume normal operation. Please see updated blog post regarding frosting on coils.




Energy Usage Explained


As the ouside air temperature increases so does the demand for energy from the air conditioning unit. Nomadic Cooling test our air conditioner units above 100F to determin maximum power consumption. Power consumtion will be stated as followes: 12V @ 5/75 Amps In this example this unit will consume up to 75amps when the outside temperature is over 100F. However, when the outside temperature decreases so will the demand for energy. PLEASE REMEMBER: When designing your battery bank size energy consumption will fluctuate based on ambient temperature.




Made In USA?


Curtrently all Nomadic Cooling air conditioners final assembly, filling, and testing is done in our Phoenix Arizona facility, although many of our components arrive from around the world. We are thankful for our international partners contributions but Nomadic Cooling is working hard to bring production and sourcing of components within the United States. This is an ambitious plan that will take time to fully execute, please feel free to ask any questions regarding the components of your current or future Nomadic Cooling air conditioner. Our fundamental goal is to create the best products period!




Typical Cost of Professional Installation.


You may decide to have a reputable builder/outfitter install your new Nomadic Cooling air conditioner? If you do, installation of the unit and the electronics that accompany the unit will cost around one thousand dollars. *Cost guidelines only pertains to the ac unit, not the complete electrical system. If you are looking for a builder/outfitter in your area please give us a call and we can point you in the right direction.




Logos on Air Conditioner?


Nomadic Cooling does not place a logo on the outside of the Air Conditioning unit for three reasons. 1: 1/2 the units get painted a custom color and the decal would have to be removed anyways. 2: If you love your ac unit you will tell people where you purchased it. 3: Decals are not always aesthetically pleasing. If you love your air conditioner and would like a logo please let us know and we will gladly send you a few.
