In calculating cooling load of outside air,
Data:
Inside -
DBT (in ℃) = 25
Wi (in Kg/ Kg of air) = 0.010983205
Outside
DBT (in ℃) = 40
Wo (in Kg/ Kg of air) = 0.026247157
[indent]Air flow rate = 3 m3/s
Equation:
SH Load = mass rate * Cp * dT
LH load = mass rate * Cp * dW
Method 1: (It...

Yes, I am trying to go for refrigeration cooling for a laying hens poultry shed in tropical climate.
The temperature varies from minimum 18 deg cel. to 42 deg. cel. maximum throughout the year.
This new design will be like an theoretical experiment from which its implementation...
Hi,
I have the following data from which I need to calculate the electrical energy consumption.
1. Capacity of the refrigeration unit = 50TR
2. Ventilation Rate = 10000 CFM
3. Usage = Would in use for 12 hours for 3 months.
Need to find Electrical energy consumption for the given period.
Any...

I have tried all of that, but can not seem to find any relevant data.
As all the data given is for a evaporative cooling system in which wind chill effect is used for cooling.
But as I am designing an AHU the ventilation rate would be lot less than the evaporative cooling system...
Hi, I am designing a ventilation system for poultry house.
I need the required outside air flow rate (i.e. ventilation rate) for a poultry house to find out the capacity of ventilation system.
I have checked the ASHRAE applications handbook, which gives the data for ventilation rate for a...

The exhaust is to the roof. So it is far away from the heat source.
I have the following data from which I need to find the total capacity of AHU
1. Inside, Outside- DBT and RH
2. Ventilation rate
3. RSH and RLH
4. Room dimensions
Now the problem is when I calculate the sensible...
@BronYrAur
The 40% SH and 60% LH load are just the occupants and equipment loads inside the room.
The outside air load would be different, that might just shift the load percentages but still the LH load is higher.
I am getting ERSHF = around 0.3
For which is does not intersect the saturation...
I am new to HVAC designing and I am working on an AHU as an intern.
I have some uncommon design conditions, for which I could not find any resources or help.
The cooling loads and ventilation requirements are very different than usual requirements. They are as follows,
Cooling loads: Sensible...
