Optimum working climate in light-duty vehicles High interior temperatures and poor air quality lower the driver's capacity to concentrate and increases the risk of falling asleep at the wheel.  An air-conditioning system can help to reduce this risk and  not only generates well-being, it increases safety at work and on the road. And it does so all year round. Webasto provides two differents systems: Roof-mounted and integrated air-conditioning solutions.Roof-Mounted Air-Conditioning SystemsA workplace with good air-conditioning enhances concentration and increases safety. Webasto rooftop air-conditioning solutions are as efficient as they are  compact.   Customised options are available and the units are simple to retrofit.  The rooftop air-conditioner can also be painted in the colour of the vehicle by your chosen bodybuilder/vehicle converter.Integrated Air-Conditioning SystemsOur comprehensive range of integrated air-conditioning units offer comfortable and reliable temperatures.  

They can be integrated either under the dashboard or the roof, installed in the vehicle ceiling or vertically, these climate control systems allow for the flexibility that the different vehicles may require. These customised air-conditioning solutions are equipped with high-efficiency fans and blowers that deliver a constant airflow and ensure a long service life. A wide variety of available accessories and kits for vehicle-specific installation includes rooftop or under-chassis condensers, control units, air vents and ducts and installation kits. For the optimum complete climate solution, some models have the added benefit of a heating function.Rooftop HVAC equipment: this article describes rooftop mounted HVAC systems - rooftop air conditioners, rooftop heat pumps, and rooftop heating equipment. We describe types of roof-mounted HVAC equipment and common inspection points, operating problems, and repair approaches. At page top is a roof mounted swamp cooler or evaporative cooling system on a private home in Tucson.

Rooftop mounted central air conditioning systems may include both the cooling unit (evaporator coil, blower fan, filters) and the compressor/condenser unit in one package. At above right is a complex of roof-mounted AC/heat pump systems on a Christchurch, New Zealand high rise building roof.

the rooftop cooling system may be connected to duct work which in turn blows down into multiple building areas to deliver cool air, drawing return air from one or more centralized returns. In many commercial installations, the entire area over a suspended ceiling may serve as one giant return plenum through which pass the supply ducts, delivering air to individual supply registers. While the list above describes the common components of a typical residential air conditioning system, other configurations and packaged units are also in increased use in both residential and commercial installations. Alternative HVAC designs may combine all components except for the duct work in a rooftop mounted unit such as the one shown above where it was mounted on a flat roof over offices at a commercial building. The outdoor compressor/condenser unit of split-system air conditioners and heat pumps is also commonly mounted on rooftops, especially flat or low-slope roofs such as the unit shown at left.

Installation requirements for rooftop-mounted split system compressors / condenser units include both a service disconnect (circled in our photo) and often additional measures to assure that the unit is properly padded to avoid damage to the roof membrane, and to assure that the unit is properly levelled. IN our OPINION, where rooftop mounted split system condenser units are exposed to high temperatures system operating efficiency and costs may be affeted. Details are at SPLIT SYSTEM AIR CONDITIONERS & HEAT PUMPS These photographs show what happens when a rooftop packaged-terminal air-conditioning air handler (PTAC) and horizontal runs of air-ducts are installed on a roof surface and when that air duct system is improperly sealed and also is lined with fiberglass insulation. Water ponded on the old, concave sections of air conditioning ducts on the roof of this commercial office space. As water leaked into the duct system it saturated fiberglass duct liner which in turn, had its normal coating of organic dust and debris from the building, risking

an indoor mold or pathogen problem for some of the occupants. The cure for these duct leaks was costly: it was determined that it was less costly to completely replace the rooftop ducts with new metal ducts using outside insulation than it would have been to remove the contaminated fiberglass liner, clean the existing ducts, repair the leaks, and insulate theirThe work was combined with other building HVAC cleaning and repairs. Common inspection points & functional issues around rootop-mounted HVAC equipment include: Shown at left, support system for rooftop air conditioners / heat pumps mounted on a metal roof in Christchurch, New Zealand.

I bought the exact same unit (to replace the original one -- long story) at Lowe's last fall, on sale, for $135. It's a little noisy but in 105+ degree heat, it worked pretty good in my 15' TT, parked in partial shade (grow little tree, grow!). It's built into an open-faced cabinet with only about 1"-2" protruding outside the wall, covered with a screen-like cover. If you decide on something like this, know that it recycles the condensate but still needs to sit in a pan of some sort for overflow. Good luck and best wishes. A truly happy person is one who can enjoy the scenery on a detour What style of air conditioners have you folks went with, rooftop, portable or window air conditioning. The window air conditioning seems cheaper and seems like it puts out a good deal of cold air. I use a 12v Non-Evaporative Swamp Cooler like this: Up to ~95°f = just plain water ~95°f - ~120°f = add big block of ice > 120°f = add dry ice Ice or Dry Ice will last the better part of a week, if running just water, which is the vast majority of the time, you never have to add any, since it is a sealed system.

One summer in Death Valley at 130°f I used the dry ice, and it got so cold I was wearing a sweater and had to open a window to let some heat in... We took a window AC unit from Sam's Club and built it into the front bulkhead of the bus over the windshield. We have another one (too small but older one we already owned) in the rear. It will be replaced with a larger one this spring. These were far from the first window units we have turned into built-ins. The secret to building in a window unit is to make sure it gets plenty of air to the motor and the water it generates during operation is drained away without damaging anything. Our goal was to make the units as unobtrusive, both inside and outside, as possible. Mostly from the outside. I think we succeeded as a friend drove right past our bus and asked where the AC unit was (meaning the rear one which is the one he would have seen). We have a converted school bus and prefer for it to not look too tacky so we can get into more private campgrounds.

Other reason to avoid the "window unit sticking out of the side of the bus" look is to avoid damage from trees, hail, and any other damages. We prefer a more "streamlined" look and the only thing sticking out of our (metal) roof is a small vent pipe for the waste tank. When we help convert a bus for our daughter, she will cannibalize the RV she currently lives in. That means she will use her RV rooftop AC unit which will be turned into a basement AC unit. Nothing to get scraped off the roof by low hanging tree branches or bridges. Rear view before adding the vent covers Got lots of pics on Photobucket AC Install I need to get the pics of the painted covers up. Now the big modified silver coloured vent cover is painted to match the body colour of the bus. This is merely what I did. I am not telling you to do this. I am just saying what I did. This may or may not work for Vandwellers. I am not a Vandweller. I live in a skoolie. I do not boondock so this may or may not be suitable for those who do boondock.
