Moderate Variable Refrigerant Flow System

Abstract

This paper tells about emerging space conditioning technology of variable refrigerant flow (VRF) systems. Material involved in this paper was combination from the open literature papers, private interviews with industry experts and data obtained from manufacturing systems. variable refrigerant flow systems are creative versions of ductless different systems, it consisting more indoor element to be connected to each outdoor element and providing additional features such as concurrent heating and concurrent cooling and heat recuperation processes . Variable refrigerant flow technology uses smart non-segregated controls, different speed drives, refrigerant piping system, and heat recovery to provide products with combination that include more energy efficiency, flexible operation, ease for installation processes, low sound, and consolation using all-electric technology system . VRF systems are very popular in Asia and Europe countries. And increasing support available from majorly U.S. and Asian manufacturers are availability considering for multi-zone commercial building applications in the U.S. This paper tells how computers simulating the software while operating the Variable refrigerant flow system.
