To evaluate these systems, engineers use tools like EnergyPlus , Modelica , and Carrier HAP . A detailed model must account for several critical variables:
One outdoor unit can serve up to 60+ indoor units. Modeling Variable Refrigerant Flow Heat Pump an...
The VRF story began in 1982 with the realization that refrigerant flow could be modulated. Instead of a fixed amount of refrigerant, a VRF system uses and electronic expansion valves (EEVs) to send exactly the right amount of refrigerant to each zone. To evaluate these systems, engineers use tools like
