Title Of Article :
Comparison of Energy and Exergy Analysis for Variable Refrigerant Flow System (VRF) with Different Rerigerants
Abstract :
In this study, an overview of laws of thermodynamics and variable refrigerant flow systems have been investigated. Besides, thermodynamic analysis of a sample variable refrigerant flow system has been evaluated and exergy losses of different working conditions and different refrigerants has been compared. While minimum refrigerant mass flow rate has been occured in simultaneous heating-cooling working condition of the system, maximum refrigerant mass flow rate has been occured in only cooling working condition. When entropy generations and exergy losses analyzed, minimum entropy generations and exergy losses has been appeared in simultaneous heating-cooling working condition. Maximum entropy generations and exergy losses has been appeared in only cooling working condition. When refrigerants are compared, minimum exergy losses has been occured in using refigerant R404. Maximum exergy losses has been occured in using refigerant R410A. With this study, it has been intended to increase the awareness of the subject.
