The development of energy-saving technologies is in great demand recently to stop global warming. We are committed to developing the Ejector Cycle as an energy-saving technology for refrigerating air conditioners. The ejector, which is an energy-saving technological innovation, improves the efficiency of the refrigeration cycle by effectively using the expansion energy that is lost in the conventional steam-compression cycle, and is applicable to almost all steam-compression refrigerating air conditioners, thus improving the efficiency of the refrigeration cycle. Concerning the application of the Ejector Cycle in truck-transport refrigerators, we previously released Ejector Cycle products for large and medium-size freezer trucks, which have been favorably accepted by custom-ers.
We attempted to develop a new Ejector Cycle for application in compact refrigerators, and succeeded in completing a commercial compact refrigerator incorporating a next-generation Ejector Cycle that substantially improves performance. This paper introduces the development.
