Why Air conditioning Condensing Units Need Clearance


Air conditioning condensate units are often mounted directly on the ground to save money or the engineer installing the unit lack of knowledge of the problems of not having them. The problem with mounting an air conditioning condensing unit directly on the floor is that when the weather turns cold the units performance is inhibited because it cannot get rid of its defrost condensate water on the outdoor unit when on heating. Most condensing units require at least 100mm clearance to clear the drain off condensate water and to reduce freezing up of the drain points. The eventual consequence of incorrect clearance is that the drain points ice up, the defrost water cannot drain off and the lower coil begins to form an ice ball which builds up. When the condensing unit is on heat pump mode the coil evaporation temperature can be lower than -20DegC. With the coil being at that temperature any water dropping onto it will freeze. Please see example below of units with issues in the cold.
