[Previous technology] 10-General ice water machine is mainly used in the "central system in buildings" and ice water machines have different classifications according to their structures, such as the cold consumption ring system. The machine type is divided into centrifugal, spiral, reciprocating, and scroll types. If it is distinguished by its cold and thirsty type, it can be divided into water-cooled, air-cooled, and equipment. If it is distinguished by the type of its button, the material can be divided into two types: dry type (dry expansion type) and full liquid type. X The above-mentioned straight & Lofa II is taken as an example. The refrigerant flows through the heat transfer tube inside the evaporator 15, and the ice water flows outside the heat transfer tube and performs heat exchange with the refrigerant in the transfer tube. However, The faster the flow rate of the refrigerant in the heat transfer tube, resulting in a larger pressure difference between the outlet and the inlet of the heat transfer tube, which relatively affects the compression ratio and efficiency of the East < Shield% system. Taking the above liquid-filled evaporator as an example, the ice water flows through the heat transfer tube inside the evaporator 20, and the refrigerant is filled outside the heat transfer tube and exchanges heat with the ice water in the heat transfer tube. However, in order to improve the heat transfer efficiency between ice water and refrigerant, the refrigerant must completely submerge the heat transfer tube, so the required refrigerant filling capacity is large, and the heat transfer tube can only be distributed in one half of the evaporator. M247805 = 2 Relatively affect the use efficiency of the space. Moreover, the bubbles generated by the refrigerant after heat exchange will also affect the heat transfer efficiency.
