METHOD OF TESTING TEMPERATURE CONTROL SYSTEM

摘要

space engineering. SUBSTANCE: method consists in measuring the flow rate of heat-transfer agent in liquid line of system and pressure differential between inlet and outlet of electric pumping unit. Temperature control system is tested without liquid line of payload. Pressure differential at electric pumping unit is changed till flow rate of heat-transfer agent in temperature system gets equal to required flow rate of heat- transfer agent through liquid line of payload. Flow rate of heat- transfer agent in liquid line of temperature control system is measured additionally. Difference in pressure differentials at electric pumping unit is checked for required magnitude; hydraulic losses are also checked. EFFECT: enhanced reliability of test results. 3 dwg
