Air conditioning systems are purchasable in many forms and sizes. Find the one for you.
Regardless of how you use your boat, a refrigerator on board can be handy. If you are the owner of a smaller vessel, you don’t have to worry about a fridge that takes up too much space. You can simply customise the unit to fit into the space you have, efficiently. There are many variations of marine refrigeration systems available on the market. The all have different advantages and disadvantages and the selection of the perfect refrigerator for you will depend on the size of your boat and how you use it.
The first type is the isotherm refrigerator, which is compact in size and can open either at the top or the front. This is the most preferred cooler system for you especially if you have enough room to fit it on-board. Isotherm units fit neatly in the cabinet systems where you will have made space for it. Connectable with just a couple of wires, this unit is purchased pre-insulated and does not require additional insulation. This unit provides excellent cooling and is able to achieve cool temperatures very quickly.
The holding plate is another type of refrigerator system, which gets its name due to its ability to retain cold temperatures for protracted periods at a time. The thick plates are cast from aluminium or stainless steel they comprise internal tube systems, which consist of cooling refrigerant. This type of cooler also retains temperatures very quickly. Comparable to a block of ice, the trick of the holding plates is in the ability of the refrigerant to freeze, thereafter staying cold for long periods at a time.
The disadvantage of holding plates is that they use large amounts of power to stay cool, in comparison to isotherm refrigerators. On the other hand, cooling only needs to take place once a day as the plates retain temperatures for hours. The plates can be cooled while running the generator or engine. The holding plates also require additional insulation.
Portable ice chests are an option for people who do not spend too much time on-board their boats. Just as its name suggests, this refrigeration system is mobile and can be transported to and from the boat. A simple solution if you do not have too much money to spend on refrigeration too.
Built-in ice boxes are a variation of the ice chest save the face that it stays fixed on the boat. This inexpensive option is also great because it does not use up energy and there is no need to power it up. They hold up well against the competition, with top of the range models being capable to keep ice in its frozen state for longer than four days.
The functioning of a refrigerator depends largely on the availability of space and power. These are the two key factors to consider in selecting the unit for you. Powered units tend to consume large amounts of energy and if you intend to operate on battery power, consider how much capacity your battery can handle, in conjunction with all your other devices that may need power.
With all this in mind, you are ready to make an informed buying decision.
