영문 초록

The different evaporation temperatures and condensation temperatures, using a refrigerant with a characteristic for high temperature side and low temperature side Cycle to Cycle, each configured for a one side to the other Cycle in binary refrigeration to get the evaporation temperature of the low temperature impact test. Results could be confirmed that the other side Cycle 1 of the evaporator and the condenser from the outlet side of the heat exchanger by heat exchange with each other Cascade Cycle of one impact. In other words, although not a random operation Cycle primary components of the increase in the amount of open secondary expansion device to transfer more of the heat exchanger into the primary through the Cascade and this change increases 1 Conpressor suction side refrigerant status to ultimately 2 was confirmed by testing the arrival of a difference in the primary winding Cycle as well. Was confirmed that the evaporation temperature of the low temperature can be obtained affect each other through the Cascade Cycle device that is configured independently of the refrigerator through the two won in this experiment, respectively.
