| الملخص: | Every classroom should have a good grade and quality to make sure the learning
process runs optimally. One of the factor that influences the grade and quality of the learning
process is the condition of the room. Temperature and humidity are some parameters that
determines whether a room would be suitable to be occupied.
On a preceding research, a simulation of classroom 4104-4105 have been done using
dry air to analyze the condition and the comfort parameter of that classroom. On this
undergraduate final project, classroom 4104-4105 simulations has been done using moist air.
The simulation condition variates the number of people occupying the classroom between 51
and 94 and the door or window are variated in open or closed condition.The purpose of this
undergraduate final project is to compare the result of the simulation using dry air with the
simulation using moist air along with effect of humidity. Besides that, the comfort criteria
have been analyzed based on ASHRAE Standard 55 and SNI to determine the suitable
condition for learning process.
Based on the simulation result, there are differences between the simulation using dry
air and moist air. On the simulation using moist air, the final room temperature is higher, the
simulation duration is longer, and the slope of the temperature drop graph declines more
steeply than simulation using dry air. However, during the simulation with 94 people with
enviromental conditions in September 2015, the final room temperature is lower than the
simulation with 94 people with environmental conditions in September 2013. This low
temperature phenomenon is caused by the high number of RH in the moist air in the room.
Comfort conditions or thermal comfort is evaluated by specifying 6 points in classroom 41044105
for
each
simulation.
The
results
shows
that
the
comfort

is
achieved
at
point

and

51
people

and
point

the
simulation
