New Dometic Replacement Cooling Units

The new Dometic replacement cooling units are designed for a much longer life than the original equipment. They use heavier wall seamless tubing that won’t fracture and a boiler design that won’t overheat.

In order to make the substitution possible, the existing products and production equipment need to be redesigned. This is a long-term project, which takes time and money.

Evaporator

Despite the design of a dometic refrigerators looking like residential type fridges, the actual cooling unit is unique in its technology. Instead of a refrigeration system containing compressors, cooling units use gas absorption to cool the ammonia vapor that is drawn into them from the tank.

This is a major step towards silent and vibration-free operation as well as extended product life. It also allows for greater flexibility regarding the energy source and makes for a better environment to operate in.

The evaporator tube set is galvanized for corrosion protection and then encased in the polyurethane foam pack. This protects against moisture entrapment and can dramatically extend the life of the cooling unit.

The evaporator is then hand tested for leaks using a burning sulfur stick. If any area of the unit containing tubing is found to have a leak, it is replaced with a new one that has been galvanized. It’s a simple but important step that will help you save money by avoiding costly repairs down the road.

Boiler

The boiler of a new Dometic Replacement Cooling Unit is an important part of your RV’s refrigeration system. They are used for both gas and electric heating and come with a variety of fuel choices.

They are also a popular choice for supplemental air conditioning. Often they are installed in conjunction with central air conditioners or ductless mini-splits.

Most Dometic boilers are made with a tube in the center that delivers hot water or steam to radiators, baseboard heaters, or subfloor radiant heating systems. These tubes are called flue tubes and are painted red or black.

Some left-hand Dometic boilers have a series of crimps along the boiler tube. These are the ideal places for mounting an ARP temperature sensor (thermal switch). Typically, one installs it on the flat part of the boiler tube just above the electric heater element. It is important to insulate this so the sensor reads only the boiler tube and not the flue tube or electric heater element.

Heat Exchanger

The Heat Exchanger is an important piece of equipment in New Dometic Replacement Cooling Units. It is used to transfer the heat from the cooling fluid to the process or utility fluid.

There are many different types of heat exchangers and each has its own advantages and disadvantages. The most common type of heat exchanger is a double-pipe heat exchanger, which uses two concentric pipes with different diameters to transfer heat between process and utility fluids.

Another type of heat exchanger is a plate heat exchanger. These use conductive plates to transfer the heat between the fluids.

Other types of heat exchangers include air fin coolers, which are used to cool a fluid with the help of ambient air. They are also commonly used to cool seawater in desalination systems and waste heat recovery systems. These heat exchangers can be configured for counter-current or crossflow. The most efficient design is a counter-current flow because the temperature difference is constant over the length of the heat exchanger.

Controls
