I would like to simulate the temperature in a room with an internal load

What you will need is to artificially prepare a weather file with the appropriate outdoor conditions.  Fortunately, this is fairly easy with the EnergyPlus WeatherConverter program (folder preprocess\weatherconverter)

Generate a .csv file of your appropriate location.  Take that file into Excel for easy editing, and replace the dry bulb temperature with your 22 C temps.  (You will need to determine an appropriate dew point as well).

Delete the rows beyond where you want the simulation to proceed (or not).  And ask the Weatherconverter program to convert a .csv file to the normal .epw file.

Then, you can use this as your weather file for the simulation.
