Title
(EN) AIR CONDITIONING SYSTEM HAVING TWO-STAGE COMPRESSION
(FR) SYSTÈME DE CLIMATISATION À COMPRESSION BI-ÉTAGÉE
(ZH) 具有双级压缩的空调系统
Abstract
(EN)
An air conditioning system having two-stage compression, comprising a compressor (1), a condenser (2), a throttling element (3) and an evaporator (4) which are sequentially connected, and further comprising a pressurization unit provided between the compressor (1) and the condenser (2), the pressurization unit being configured to convert natural energy into mechanical energy, so as to perform secondary pressurization on a refrigerant discharged from the compressor (1).
(FR)
L'invention concerne un système de conditionnement d'air ayant une compression bi-étagée, comprenant un compresseur (1), un condenseur (2), un élément d'étranglement (3) et un évaporateur (4) qui sont reliés de manière séquentielle, et comprenant en outre une unité de mise sous pression disposée entre le compresseur (1) et le condenseur (2), l'unité de mise sous pression étant con4ue pour convertir l'énergie naturelle en énergie mécanique, de façon à effectuer une pressurisation secondaire sur un fluide frigorigène évacué du compresseur (1).
(ZH)
一种具有双级压缩的空调系统,包括依次连接的压缩机(1)、冷凝器(2)、节流元件(3)和蒸发器(4),还包括设置于压缩机(1)和冷凝器(2)之间的增压单元,增压单元设置成能够将自然能转化为机械能从而对压缩机(1)排出的制冷剂进行二次增压。
