<p>There is described an apparatus and method for cleaning the condensers 16 in the refrigeration circuits of retail chiller cabinets 1, wherein an enclosure 20 is placed over the condenser and the air passages 54 of the condenser 16 are sequentially sprayed with detergent, water, and air to remove blockages from the air passages. The enclosure 20 may include a movable spray bar 28 having nozzles 29 for spraying air and/or water into the air passages. Sensors 51, 52 may be provided to determine the degree of blockage of the air passages either before or after cleaning, either by optical means or by blowing through the passages and detecting pressure or airflow at the exit. Liquids may drain from the enclosure through a drain opening into a collection tray placed beneath the enclosure, from where the liquid may be pumped to a collection container or to a drain.</p> |
