Fluorine pump liquid supply is a refrigerating system which conveys low temperature refrigerant liquid to evaporator by the mechanical effect of bump.
　
Firstly, low temperature refrigerant liquid after throttling will enter a fluorine barrel with certain capacity for storing the liquid or separating the gas and liquid. Then the low temperature refrigerant liquid which is many times more than evaporation will be conveyed to the evaporator in every Warehouse by fluorine pump. And part of the liquid will boil off when it is heated in the evaporator, while the rest of the liquid will return to the fluorine barrel through muffler. After gas-liquid separation, the steam will be siphoned off by the refrigeration compressor. The separated water and the newly added water which is equal to the evaporation will be conveyed to the evaporator and recycled by fluorine pump.

(1) Evaporator has high evaporation and heat exchange efficiency and good cooling performance.

(2) It enables long-distance liquid supply.

(3) The operation of the system is simple and reliable which makes it is easy to centralize control and make the machine automated. And the working condition in the refrigeration compressor can be improved.

(4) It is easy to defrost.

(5) Defrosting with hot fluorine which makes the machine energy-efficient.
