Refrigerating cycle

摘要

A refrigerating cycle is equipped with an electromagnetically actuable differential pressure regulating valve 10 constituting a pressure reducing device 3 between a condenser 2 and a receiver 4, allowing to set the differential pressure regulated by the differential pressure regulating valve 10 between a certain amount and zero to cause an operation in which the maximum cooling power is unleashed and an operation in which an excellent performance coefficient is attained. <IMAGE>
