Hello everyone,

I am currently working on simulating a cold room storage using Refrigeration Equipment, and I am referencing the Refrigerated Warehouse example that utilizes the airchiller object - Fig.1 - (more details).

I have a question regarding the Refrigeration Air Chiller System Evaporating Temperature output variable, defined in the EnergyPlus documentation as the 'saturated evaporating temperature.'

I've plotted it over the simulation time and observed that it remains constant throughout, specifically at -24 °C, as specified in the 'Rated Cooling Source Temperature' within the airchiller object - Fig.2 -.

Can anyone clarify whether this value is expected to be constant during the simulation or if it should vary with time? Your insights would be greatly appreciated.

Thank you!
