When selecting DX evaporator coils and matching condensing units, it’s important to calculate the balance point at which they operate. If the condensing unit has more capacity than the evaporator coil,
the suction temperature will be low. Sometimes, this is the desired affect if you are looking for dehumidification, cold air and lots of latent capacity. Alternately, if the condensing unit is relatively smaller than the evaporator, the suction temperature will be higher. This could be useful when you want to avoid dehumidification such as a data center or telecom room.
