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
