", https://www.ahridirectory.org/Search/SearchHome. Condenser vs Thin Film Evaporator. A condenser coil is a network of a tube that is fitted to the outdoor AC unit. The evaporator is usually installed in housing under the dash panel. Oversizing the evaporator can actually lead to increased head pressure as the condenser must now reject more heat from the system due to the increased "heat absorbing" capacity of the evaporator. In many locations around the world, regulations limit the physical size of a cooling system and this in turn limits the use of evaporative condensers. When I search "next size up evaporator greater efficiency", these are the top results: "Yes, it’s bad if your evaporator coils are sized bigger or smaller than your condenser coils." Should my AC condenser and evaporator be the same size? To learn more, see our tips on writing great answers. Does paying down the principal change monthly payments? Evaporator equipment is typically designed to produce a thin film on a heated surface so that solvents … These were not directly heated by a flame, but had a primary steam circuit using main boiler steam through coils within a steam drum or evaporator. Bigger evaporator coils and smaller condenser coils cool your home at desired temperature but humidity can be left too high since it can remove little to no moisture at all.
