I am trying to simulate a walk-in freezer in EnergyPlus using the Refrigeration:Walkin model and see how the internal temperature of the walk-in freezer evolves.

I used the example of the SupermarketDetailed in the E+ documentation (without modifications), where a walk-in freezer was simulated to better understand how the Walkin model works. The cold room freezer was placed in the "backroom" zone and characterized by an operating temperature of -2.2°C;

I am trying to simulate a walk-in freezer in EnergyPlus using the Refrigeration:Walkin model and see how the internal temperature of the walk-in freezer evolves. I used the example of the SupermarketDetailed in the E+ documentation (without modifications), where a walk-in freezer was simulated to better understand how the Walkin model works. The cold room freezer was placed in the "backroom" zone and characterized by an operating temperature of -2.2°C;

I set the Backroom Zone air temperature as an output, expecting it to be the temperature inside the walk-in freezer and below zero. However, I was surprised to find that the temperature was above zero (between 19.7 and 20.7°C).

So my question is: can we track the temperature variation inside the freezer? In other words, can the Refrigeration:Walkin model calculate the temperature variation inside a Walk-in freezer?
