Summary

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.
