    1. Beneficial Refrigerant Stream (BRS) Evaporator


      1. The Beneficial Refrigerant Stream (BRS) evaporator is composed of tanks, tubes and cooling fins. The tubes project outwards and are shaped as a fine duct in an attempt to offer superior conductivity with a narrower width. Furthermore, the evaporator has been drastically miniaturized and lightened through efforts to promote conductivity through shrinking the fin height, tube thickness and fin pitch, as well as by thinning the core material.

      2. The route that refrigerant passes through within the evaporator is optimized and pressure losses are reduced in an effort to increase performance and decrease size.


        1. Refrigerant Route


          • While flowing through the evaporator tubes, refrigerant exchanges heat and vaporizes from a mist state.

          • As shown in the illustration below, the proportion of tubes through which refrigerant flows increases as the direction the refrigerant flows in changes. This makes it easier for refrigerant to flow and decreases pressure losses.

    2. Cold Strage Evaporator


      1. The cold storage evaporator is composed of tanks, tubes, cooling fins and cold storage cases.

      2. The cold storage cases with built-in cold insulators are structures sandwiched between tubes used as refrigerant passages and can store cold energy in a short amount of time.
