Abstract
This paper presents the development of a CO2 gas cooler model using the moving-boundary method. The model aims to separate the gas cooler into two regions: supercritical gas and supercritical liquid by means of the CoolProp thermophysical property library (Bell et al., 2014). The model uses the latest correlations for refrigerant and air-side heat transfer coefficients and pressure drops. The experimental results from Ge and Cropper (2009) are used for model validation. A total of at 36 operating conditions have been reported. The model predicted the gas cooler heating capacity within an MAE of ±4.7% and refrigerant side outlet temperature within ±3 K. The present moving-boundary model also showed an improved agreement compared to the segment-by-segment model proposed by Ge and Cropper (2009).
