    摘要： Method of assembling a vacuum insulated piping run for conducting a cryogenic fluid in which piping sections are produced in a first location and then assembled in a second location into a piping run. Each of the piping sections incorporates an outer cylindrical casing and an inner pipe for transport of the cryogenic fluid to form an inner annular region for containing insulation that can be radiation shield insulation and aerogel blankets. The piping sections are joined by welding the ends of the inner pipes together and then joining the outer cylindrical casing by a shell-like section. Points of connections are tested by vacuum testing techniques as each of the connections is made. Thereafter, the annular region is purged with a condensable gas such as carbon dioxide and subjected to a subatmospheric pressure.

    摘要： Bei einer Vorrichtung zur Ermittlung von Druckverlusten in einer Druckleitung (3), die mittels Absperrventilen (11, 13) während einer wählbaren Zeiteinheit absperrbar, an die Verbraucher (4, 5) angeschlossen sind, und die mit einem Druckwächter (15) versehen ist, ist der abgesperrten Druckleitung (3) über eine Zweigleitung (24) in einer Zeiteinheit eine einstellbare Menge des eingesperrten Druckmediums zuführbar und der Druckwächter (15) ist mit einem Schaltkreis (31) verbunden, mittels dem in Abhängigkeit von dem Betriebszustand des Druckwächters (15) die Druckleitung (3) beeinflussbar ist. Mittels dieser Ausgestaltung ist es möglich, mit sehr geringem Schaltungsaufwand jederzeit oder in wählbaren Zeitabständen eine Überprüfung der Druckleitung (3) vorzunehmen und in Abhängigkeit von dem Messergebnis die Versorgung der Verbraucher (4, 5) wieder aufzunehmen oder die Druckleitung (3) stillzusetzen.

    摘要： Provided is a refrigeration apparatus that detects refrigerant leakage or refrigerant charge deficiency while restraining costs increasing. An air conditioning system (100) is equipped with a subcooling heat exchanger (16), a second outdoor expansion valve (15), a first refrigerant flow rate computing component (55), a second refrigerant flow rate computing component (56), and a refrigerant quantity determining component (57). The subcooling heat exchanger (16) includes a first flow path (161) disposed on a refrigerant primary circuit (RC1) and a second flow path (162) disposed on a bypass circuit (RC2). The second outdoor expansion valve (15) is disposed on an upstream side of the subcooling heat exchanger (16) in the bypass circuit (RC2). The first refrigerant flow rate computing component (55) calculates, as a first refrigerant flow rate (Fr1) on the basis of refrigeration cycle theory, the flow rate of the refrigerant flowing through the bypass circuit (RC2). The second refrigerant flow rate computing component (56) calculates, as a second refrigerant flow rate (Fr2) on the basis of fluid theory, the flow rate of the refrigerant flowing through the bypass circuit (RC2). The refrigerant quantity determining component (57) determines refrigerant leakage or refrigerant charge deficiency on the basis of a result of a comparison of the first refrigerant flow rate (Fr1) and the second refrigerant flow rate (Fr2).
