2. human load
3. ventilation load(fresh air ventilation load and door opening load)
are there any other factors that I should consider while calculating the dehumidifier capacity??
Infiltration load=humidity diff. b/w outside and inside *density of air * space volume * some factor
Human load=no. of people * factor
Ventilation load= fresh air load + door opening load
fresh air load=fresh air quantity * humidity diff. * density
door opening load=area of door* time(sec)door staying open * no. of openings
Any remarks plz reply.

Consider the building materials ability to allow moisture diffusion from oustide. Also consider the internal moisture load from activities.
The a/c is able to provide dehumidification only when there is sensible cooling loads. In most cases, supplemental dehumidication needed for the periods when there is low/no sensible cooling loads.
Units like the Ultra-Aire dehumidifiers have latent only with sensible reheat. Ultra-Aire has the high latent cooling and a small amount of sensible cooling.

Bear Rules: Keep our home <50% RH summer, controls mites/mold and very comfortable.
Provide 60-100 cfm of fresh air when occupied to purge indoor pollutants and keep window dry during cold weather. T-stat setup/setback +8 hrs. saves energy
Use +Merv 10 air filter. -Don't forget the "Golden Rule"
