Air cooled chillers in the picture left are particularly popular in the temperate UK climate and are easy to maintain. They get used in hot climates too as the cooling fans will still condense the refrigerant down below the saturation point. In warmer climates they are less efficient as the pressures and temperatures are higher, requiring more electricity and lowering the co-efficient of performance (COP) In the UK, because of the lower ambient, they are very effective in subcooling the refrigerant to below the saturation point. The condenser coils need to be brushed and chemical cleaned during the maintenance because the sucking action of the fan draws up dust on to the coil. Expansion related leaks can occur on the condenser- the industry is reducing this with the increasing use of micro-channel condensers
