摘要/Abstract

摘要： 为了研究一、二级节流对补气系统的影响规律,设计构建了驻车空调R134a补气系统,主要对补气增焓系统参数进行了试验研究。通过对试验数据分析研究得到补气增焓系统吸排气温度、一二级节流前后温差随一二级节流阀开度的变化规律,为后续系统设计提供理论指导。

Abstract: In order to study the influence regulation of the first and second throttle opening size impacting on vapor-injected system, the parking air conditioner R134a vapor-injected system was built. The parameters of the vaper-injected system was experimentally studied. The changing rule of the suction temperature, the discharge temperature, the temperature between inlet and outlet of the throttle valve with the first and the second throttle opening size was obtained by analysing of experimental data, which would provide theoretical guidance to vapor-injected system design.

Key words: Vapor-injected system, Throttle opening size, Parking air conditioner, R134a
