How is fraction latent, radiant, lost and convective decided for the heat gain from equipment? And why is the cooling energy higher when convective gain is 1, as compared to when the radiant gain is 1?

Greetings!

I wanted to understand how is the fraction latent, radiant, lost and convective decided for the heat gain from electric equipment? What is the typical distribution of fraction heat gain from the computer in a space?

I understand that the cooling energy is lowest when fraction lost is 1. But why is cooling energy higher when fraction latent is 1? And why is the cooling energy highest when convective gain is 1?

My results are as follows: Cooling energy when fraction lost is 1 = 14265 kWh Cooling energy when fraction latent is 1 = 16094 kWh Cooling energy when fraction radiant is 1 = 17783 kWh Cooling energy when fraction convective is 1 = 19902 kWh

Thank you.
