The larger condenser coil lowers the head pressure, while the larger evaporator coil … How Evaporator and Condenser Coils Work. Evaporator condensers are more expensive than dry coolers and are primarily used in large cooling systems or systems where the outdoor temperature is high. You have done a fair amount of research as you can see this an art and depending on what you want lower operating cost or dryer air the answer can be different. Whether one is bigger or smaller than the other, the problems can be many. The reason is that the evaporator cannot get cold enough to properly dehumidify the air, causing your air to feel sticky and humid. Sorry to add another variable into your research but almost every system I have installed is slightly different so there is not a one size fits all unless you have a system that can vary it’s pumping rate then an equal match is best so you have efficiency for most of the day and dehumidifier for a couple of hours. The condenser has to have good air flow and must be mounted properly. Regular cleaning of the evaporator coil and the filter is … rejects the heat from the refrigerant. The high efficiency is obtained by using a larger condenser surface or by using more modern alloys with more extended surface or fins 6. Wiped film evaporators are typically used with highly viscous fluids or slurries that will not readily form a thin film on a heated surface.. A wiped film evaporator uses a rotor with an attached wiper that will wipe a thin film of the product onto a tubular heated surface as it turns. Why does the US President use a new pen for each order? As shown in Fig. 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.
