Study of Refrigerant Circuitry of Evaporator Coils with a Distributed Simulation Model
نویسندگان
چکیده
This study attempts to establish a general method to analyze the performances of evaporator coils with complex tube circuitry using a distributed simulation model, which has three elements: branch, tube and control volume. The governing equations for a control volume are presented in the paper together with the computer simulation procedure for branches, tubes and control volumes of a coil. Using this model, the heat transfer and fluid flow characteristics of the coils are studied with R134a as a refrigerant. A guideline is proposed for the refrigerant circuitry arrangements in order to improve the coil comprehensive performance.
