Curtains and roller blinds
To maximise cooling efficiency and reduce humidity all air conditioning units must maintain a free flow of air. The CMC air conditioning unit works on the same principal as a larger split-pack unit and recycles air within your motorhome or caravan. In this blog we will look at curtains and blinds.
If you pull down a top fixed roller blind behind the fan unit the amount of air drawn through evaporator coils is reduced. It will not harm the unit, but ultimately less air flow means less cooling. In Europe, many campers use silver insulated window covers on the outside but even something as simple as white card will reduce the solar gain.
Don’t be tempted to draw curtains tight either side of a window fixed CMC unit. This will almost certainly reduce the through the flow of air making cooling a longer process. Worst still surrounding the fan unit with curtains and blinds often means that warm air is drawn in from the gap in the bottom of the window which is warm (or hot) with a high RHG relative humidity so the dehumidifying effect of the CMC unit can be gravely reduced.
In real life a compromise is often required and the CMC unit will still work if one or both of the above potential issues are encountered. This is just advice on how to get the best from your unit.
