That combined with any heat used to make the steam/moisture has to be removed as well can lead to 2 to 3 times extra refrigeration capacity being needed. This takes out the need for a humidifier to constantly put moisture back in the room to offset what is taken out by the evaporator. For long runs over 50 feet or runs with alot of rise where the evaporator is higher than the condensing unit it is a good idea to utilize an oil separator to minimize the amount of oil that leaves the condensing unit. The epoxy seals this area so the coils won’t get attacked by the acetic acid. With a regular superheat controlled TXV the suction pressure/temperature can even dip below that point and lead to even more dehumidification of the air. Thank you. Another method for sizing air conditioners is determining the size of the air conditioner system that's currently in place. Use this chart when matching coil with an outdoor unit with a different nominal capacity than the coil. Consult with local authorities having jurisdiction before supersede installation.
