The cold-air delivery ducts extend from the farther end of the bruie-spray compartment. the coils are washed periodically with fresh water to remove the frost. In the latter case warm water from the condenser is generally used. These units usually discharge air at the top, either into ducts or through nozzles, and return it to the coils through openings near the floor. When the return air is picked up in the lower part of the room, it is difficult to get the best distribution of temperatures. A unit cooler installed with air ducts for a better distribution of refrig- eration is shown in figure 7. When defrosting is intermittent, it is important to make the cycle short enough to keep the coils fairly free from frost. A thin layer of frost interferes with heat transfer just as on other types of coils and also reduces the quantity of air circulated on account of the close spacing of the cooling Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hukill, W.
