Just as the electrical coils that comprise heat strips warm the air that comes out of your heater, evaporator coils cool and condition the air that is released from your air conditioner. Your evaporator coil removes heat from the air . • Larger evaporator coils are normally supplied with liquid distributors for the specific circuiting requirements. However, ice can sometimes form on evaporator coils for a variety of reasons, such as dirty condenser coils or blower fan blades. The problem with this is that, if the "oversized" coil is too large, short cycling can result. 4. I don't need a new furnace, but the bigger evaporator coils will not fit inside my old girl, which works quite well otherwise. So is it possible it could be a wash, with a standard PSC motor. Depending on how much bigger your condenser and what type of metering device choose you may get flooding on startup as well during run cycle. “Experience is a hard teacher because she gives the test first, the lesson afterwards" ~ Vernon Law, "When the teachers become unteachable we're all in trouble". 0000172027 00000 n On the other hand, using an evaporator coil that is larger than the condenser coil can cool the air in your home. I am getting quotes for a new R410A condenser unit/evaporator coil from several HVAC contractors. One kind of evaporator is a kind of radiator coil used in a closed compressor driven circulation of a liquid coolant. 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. 0001094050 00000 n appropriate evaporator coil or air handler (which has an evaporator coil built in). 0000151735 00000 n This combination of refrigerant feed, circuiting, and tube diameter, results in the greatest evaporator charge inventory possible. what is downside to using larger evaporator coil?
