How to choose the right air conditioner
Example: You own a yacht and would like to aircondition a room of 5 m (length) x 5 m (width) x 2 m (height).
Step 1: Define the category of the cabin Determine the category of the cabin . We give an example for a cabin with an average glass area, for example a deck saloon. Step 2: Define the net volume Determine the net volume of the room (5 m x 5 m x 2 m = 50 m 3 ; subtract 20 % for furniture in the room; 50 m 3 - 10 m 3 = 40 m 3 ; If you want to air condition the whole boat, please calculate the sum of your rooms . Step 3: Define your climate region Determine the climate region where you spend most of your time. For example the Mediterrean Sea is a “normal region” in the climate category.

Step 4: Identify your cooling requirements Result: You need an air conditioning system with a 20,000 BTU / h cooling capacity .
20,000 BTU / h
Step 5: Decide between a self-contained and chiller system Depending on the demands you can decide on a self-contained or chiller system with a cooling capacity of 20,000 BTU / h.
