数码涡旋与变频技术在VRV空调系统中能效分析

Analysis on Performance Between Digital Scroll and Frequency Conversion in VRV Air-conditioning System

目前VRV空调在市场上主要分为数码涡旋VRV系统和变频VRV系统,分别对两种技术的原理进行介绍,指出了两种系统的特点和不同之处,并从理论计算和实验两个方面对变频系统和数码涡旋系统的能效进行对比分析,引入了综合部分负荷系数IPLV,并阐述了一些实际实验中的影响因素,指出了进一步研究和推广两种系统需要解决的问题。供以后设计和运用这两种空调系统形式的人员参考。

The digital scroll VRV air-conditioning system and the frequency conversion VRV air-conditioning system are the different parts of the VRV air-conditioning system in today＇s market, and working principles and the difference between them were introduced. The performance of the digital scroll and frequency conversion VRV air-conditioning system were analyzed from two aspects of theoretical calculation and experiment. The IPLV was introduced and the fnctors that maybe exist in the experiment were discussed. In the end, the major problems of both units were pointed out for further research and promnotion in the future.
