A parameter-estimation model for variable refrigerant flow heat pump systems.
Number: No 112
Author(s) : MBAYE A., CIMMINO M.
Summary
A variable refrigerant flow (VRF) model based on a simplified vapor compression cycle is presented. The outdoor unit and the indoor units are modelled separately. An optimization procedure is used to identify their parameters by minimizing the differences between the model predicted capacities and power input and manufacturer data. Calibration results show a root mean square error (RMSE) in range of 4%, 8.8% and 7.3% for the indoor unit total capacity, the outdoor unit capacity and power consumption respectively. Three configurations of VRF heat pump are evaluated using previously calibrated indoor unit and outdoor unit models. The results show that the model-predicted cooling capacity and power input are close to the manufacturer data with an average RMSE of 2.2% for both the power input and the cooling capacity.
