AIR CONDITIONING CHOICES

There are two basic types of auxiliary air systems:

Self-contained unit installed under bunk.

•Self-contained “package” units

•Split systems

The self-contained unit is designed to be wholly mounted inside the truck, usually under a berth or seat or inside a side storage locker. All of the air conditioning components, including the com- pressor, condenser, evaporator, blower and power supply, are mounted on a single low-profile chassis with an aluminum cover. The system’s closed refrigerant loop is precharged and sealed at the factory. Inside air is pulled across the evaporator coil, and cooled air is blown through a flexible duct to a discharge grill for discharge into the living area. Hot air is discharged from the con- denser through cutouts in the floorboard.

Dometic’s patented split systems consist of two separate modules. The outside unit contains the condenser and cooling fan. It can be bolted horizontally to the underside or vertically to the back of the sleeper. The inside unit contains the compressor, evaporator, blower, power-logic box and other associated components.The compressor is

covered by a sheet-metal cover. The inside unit is mounted under a berth or seat or in a side storage locker. The two units are connected by reusable precharged quick-connect refrigerant linesets. The system is designed so that both units automatically charge to the correct refrigerant pressure as soon as the linesets are connected. No special tools are required.

Each approach offers advantages and disadvantages. A self-con- tained unit is simpler to install and maintain, since it does not have any external refrigerant lines. It is also less expensive than a split system of the same BTU capacity. On the other hand, it takes more interior space, and it requires cutting

	split system, on the other hand, has more installation flexibility
	and uses less interior space. It also is quieter, since the con-
	denser fan is located outside the truck.
	Both types of air conditioning systems are available with a
	selection of built-in electrical heat modules. The heat is blown
	through the same ducts and grills and controlled by the same
	thermostat. They can also be used in conjunction with a diesel-
	fired heater if desired, under control of the same thermostat.
