This paper presents a steady-state model that is useful for predicting the performance of centrifugal liquid chillers over a wide range of operating conditions. The model employs an elemental NTU-E methodology to model both the shell-and-tube condenser and the flooded evaporator. The approach allows the change in heat transfer coefficients throughout the heat exchangers to be accounted for, the...
In this paper, a new cooling system using a nacelle duct is proposed for the mechanical room in the household refrigerator. The conventional mechanical room consists of a condenser, a compressor and an axial fan. The axial fan is mainly responsible for cooling the condenser and the compressor. The new cooling system is developed by replacing the axial fan with the nacelle duct including the sma...
Solar Energy Applications Laboratory , Colorado State University . Fort Collins , CO 80523 Design of a vapor transport solar water heater using R-123 is optimized to maximize thermal performance and minimize life cycle cost. Optimal systems for one and twostory homes are identified in a parametric study of collector area, condenser heat transfer area, water storage tank volume and circulating r...
