My case study is refrigerated warehouses, the chosen system is co2 booster system with parallel compression, modeled in energyplus. To model this system I have used as reference the examples "refrigerated warehouse" and "Supermarket Transcritical CO2". But when simulating, the following message appears:
* Warning * GetRefrigerationInput:: Refrigeration: AirChiller = "EVAP 01 Camara 01" unused.
This happens with each evaporator in the system, and the refrigeration system does not work, it does not control the temperature, neither do the compressors work, but it does complete the annual simulation in other variables, for example the lighting power. I have checked the system variables, schedules and setpoints but I cannot find the error
What is the reason for this error? Can I combine the use of a transcritical co2 system with a refrigeration air chiller?
