how to calculate cooling time needed?
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?

Re: how to calculate cooling time needed?
the time need is : cooling capacity /air volum*delta enthalpy if your cooling capaciy can balance the room heat load

The method also seems strangely familar to someone that you might know wambat.

what you say is right,it's dynamical process but you can estimate it by easier method at many occasions. Of course if it's a precision lab,you need to carefully calculate it and have a test to confirm it finally.
What I mentioned is only a clue for you; may be you can use some simulation program to run it
