Só I dont understand how E+ calculates the latent loads on an ideal system. I am using a constant supply humidity ratio both for dehumidification and humidification, but can’t connect the latent loads results with the humidity ratio found for the zone. What is the latent load connect with??

What else is going on in the zone? Infiltration? People? Is the ideal loads system adding outdoor air?

There is infiltration at rate 1/hr and 5 people with an occupation schedule. There is no outdoor air added.

The zone humidity ratio is the result of the ideal loads flow (as the specified constant humidity ratio), the latent load from people, and the latent addition or removal due to infiltration. The ideal loads system, when controlled to a constant supply humidity ratio (and with no outdoor air) simply takes the zone return air humidity ratio and lowers (or raises) it to match the specified supply humidity ratio.
