Study On The Characteristic Of Small Air-Source VRV Air-Conditioning System

A Small Air-source VRV Air Conditioning System is now widely used one which provides with the characteristics of energy and space saving, convenient installation, stable operation. There stands obvious technology gap between home and abroad due to the complexity of VRV Air Conditioning System. Furthermore, It has the important meanings and value to research because of the variety of VRV air conditioners. This thesis researches into two representative VRV air conditioning systems--Variable Frequency Control VRV Air-conditioning and Digital ScrollTM Air-conditioning system, the details are as follows:1) Mathematical models of Variable Frequency Control VRV Air-conditioning system has been set up, on the basis of which, research work into the characteristics of this air conditioning system with double-evaporator under variable condition is completed, which provides some evidences of control methods of VRV air conditioning and style-selecting of units.2) Mathematical models of Digital ScrollTM Air-conditioning system has been set up, on the basis of which, research work into the characteristics of Digital ScrollTM Air-conditioning system with double-evaporator is completed, which provides some evidences of designing of this type of conditioning system.3) Comparison work has been completed on the aspects of comfort ratio, virtues and flaws of them are analyzed.
