GE Monogram 5800 Series, 3900 Series, 2900 Series manual Latent System Capacity, Model

Latent System Capacity

The total capacity of an air conditioner is made up of the Sensible capacity, the output of the unit used to remove heat from the air in the area being conditioned, and the Latent capacity, the output of the unit used to dehumidify the air in the area being conditioned. For humid climates and applications, the Sensible/Latent capacity split of the unit should be considered. The Sensible capacity listed in the specification charts on page 55 is at a standard rating condition of 95°F dry bulb/75°F wet bulb outdoors; 80°F dry bulb/67°F wet bulb indoors. The Latent system capacity is

1.00minus the Sensible capacity. (If the Sensible capacity is listed at .74 the Latent capacity is .26. This means that 74% of the capacity of the unit is used to remove heat from the air and 26% is used to remove moisture form the air at standard test conditions.)

In some applications information about the Sensible/Latent split, or ratio, at conditions other than the standard rating conditions is needed. The chart below provides data at various indoor conditions.
