Refrigeration system in EnergyPlus

Hello community,

I have gray vision on how the refregiration system works and I want to echange with you my thoughts. Please fill free to correct me if I am wrong.

image description

It starts with calculating the internal loads of the refrigerated case using the heat balance model so we know the heat that needs to be rejected. image description

The stat of the refrigerant information is passed to the compressor model and uses the performance curves to calculate the compressor power and the cooling capacity.

image description

The information on refrigerant state is then used in the condenser model to calculate the condensing temperature and enthalpy of the refrigerant entering the refrigerated case as well as the condenser fan power. The condenser is modeled via the heat rejection performance curve.

image description image description image description

The air inlet temperature and evaporating temperature are used to calculate the actual cooling capacity of the evaporating system (i.e. the air chiller object with European Standard Ratings).

image description

The sensible and latent loads are then calculated as:
