I have a question like bellow:

At the beginning, the room temperature and ambient temparature is the same, for example ( 35℃ DB, 70%RH), I want 27℃ DB, 60% inside finally.

the given air conditioner is 10 Kw for example, the thermo transfer coeficient K is 2.4w/m2.c.

let's say the room size is 3m*3m*3m

how to calculate the necessary time?
