Development of the High-efficiency Heat Pump——Two-stage Compression System for the Cold Area

摘要

This paper mainly introduces the technical characteristics, system composition and main features of Daikin's new-generation high-efficiency heat pump system-two-stage compression VRV. As a heat pump system, the two-stage compression VRV solves the heating problem faced by the traditional heat pump system at low ambient temperature,and noticeably improves the heating capacity, heating efficiency and indoor comfort.This paper also points out that,as an energy-saving and high-efficiency heat pump system, the two-stage compression VRV has a good prospect of extensive application in the cold area.
