FIELD: mechanical engineering; transport engineering. SUBSTANCE: invention relates to systems for filling vehicles with vapor forming working medium. Proposed method consists in filling working medium (liquid phase) into tank and forming out working medium (vapor phase) from gas space. Forced out working medium (vapor) is cooled (condensed) to temperature of filling-in working medium and both media are mixed at combined filling. Proposed device contains tank to be filled, filling and drain lines, heat exchanger and jet pump. Pump high-pressure inlet is connected with filling line, and low-pressure inlet is connected through heat exchanger, with drain line, while pump outlet is connected with tank to be filled. According to proposed method warming of gas space caused by compression at filling-in is compensated owing to draining of gas from space ad cooling of gas in heat exchanger, thus providing more complete filling of tank. EFFECT: on environment, simple filling, provision of reliability and reduced power consumption. 3 cl, 1 dwg |
