دانلود مقاله مروری بر اجزاء یک سیستم تهویه مطبوع با جریان مبرد متغیر برای کاربردهای خانگی A Review of Variable Refrigerant Flow HVAC System Components for Residential Application

A variable refrigerant flow (VRF) classification is a multi-split Heating, Ventilation and Air
Conditioning (HVAC) system that controls refrigerant flow to control separable zones to
residential consumer’s needs. VRF specific components regulate refrigerant flow control for
system performance and reliability. The objective of this review is to recognize the VRF system
components that affect various aspects of operation and performance. The investigate of
preceding experimentation will better assist in the direction of future progress as development of
expansive residential VRF systems are still in primary phases. Findings show that specific testing
through different compressor arrangements, electronic expansion valve (EEV) positioning, and
air flow operations affect performance and thermal comfort. The system responsiveness and
sensitivity are related to the quantity of indoor evaporators that are connected to the system.
