Sensible heat ratio (SHR). The sensible share of a cooling duty, the rest being moisture condensed out; the slope of the process line on the chart. Draw one on the free chart.
The sensible heat ratio is the share of a cooling duty that lowers the air's temperature, the rest being latent — moisture condensed out. A coil cooling dry air has an SHR of one; a comfort coil in a humid climate runs at 0.6 to 0.8, and a dehumidifier's is lower still. On the psychrometric chart the process line's slope is the SHR: a steep line is mostly latent, a flat one mostly sensible. The room has an SHR of its own — people, ventilation air and infiltration add moisture, lights and sun do not — and a coil whose SHR is higher than the room's leaves the humidity climbing however cold it blows.
A coil's SHR is set by its geometry and its conditions: a deeper coil, a colder surface or slower air drives the leaving state closer to the surface temperature and takes more moisture out, so a coil selected on temperature alone may be the wrong one for the moisture. Every process the solver reports carries its sensible duty beside its total, and a building simulation treats the moisture balance separately from the sensible load — which is why one machine can carry a room's latent load while another carries the rest, and why a room's humidity ceiling can make a unit over-cool and reheat.
Open the builder — the examples in the Design tab's sources list include a machine of this kind, and the Simulate tab runs it against a year of weather.
