what i mean is, the static pressure for hot return air ( red colour arrow) and the static pressure for cold supply air ( blue colour) in the AHU as shown in the picture. What is the effect if the static pressure for blue colour arrow is greater than red colour arrow and vice-versa?
thank for...
room size : 3 m x 7 m, height 3 m
heat load : 10000 btu/h
cfm : 644
velocity: 6 m/s
temperature : from 30 celcius to 22 celcius
chilled water flow rate : 30.8 liter/minute
altitude : sea level
how can i calculate the require time for an air-conditioning unit to cool from 30 degree celcius to 22 degree celcius? others parameter can be ignore, i would like to know the formula used and the principal of calculation. thanks
