GE 5500 manual Latent System Capacity, AZ25E07D/E AZ35H07D/E AZ55H07D/E SHR 74%

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 pages 52 and 53 are at standard rating conditions of 95°F. dry bulb/75°F. wet bulb outdoors; 80°F. dry bulb/67°F. wet bulb indoors. The Latent system capacity is 1.00 minus 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 from 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 charts below provide data at various indoor conditions. To use the charts, first determine which Zoneline model is being considered and refer to the appropriate chart. Next, locate the indoor dry bulb temperature under consideration across the horizontal axis of the chart and draw a line straight up until it touches the line representing the indoor wet bulb temperature of the area; from this point draw a horizontal straight line to the vertical axis. The point where the line touches the axis represents the latent percent of the total capacity of the unit. An example is shown for the standard indoor conditions of 80°F. dry bulb/67°F. wet bulb.
