CO2 Cabin Pipeline Temperature Cycle Pressure Pulse Test Bench

【Applicable standards】

DIN SPEC 74106-2015 Road vehicles-R744-Air conditioning systems-Refrigerant lines and IHX in coaxial design;

【Technical parameters】

Bending radius: 180°, connect both ends to the equipment pressure source. Environmental chamber temperature range: -28℃-165℃, and pulse pressure range: 5MPa-17MPa. Pulse pressure cycling according to the curve in the figure. 20000 pulse pressure cycles at -28 ℃ in the low-temperature range; 30000 pulse pressure cycles at 165 ℃ in the high-temperature range; Whole temperature cycle is repeated 5 times, with pressure pulse cycle of 250000 times during high and low temperature changes. Requirement: All test pieces must be leak free and undamaged.
