26 Fluorine Barrel Pump Unit Fluorine Barrel Pump Unit The high efficiency fluorine pump liquid supply system is a kind of refrigerating system that employs mechanical action to transport low refrigerant liquid to evaporation terminal. The throttled low refrigerant liquid would enter the low pressure storage recycling barrel (include liquid storage volume and gas-liquid separation volume), then the fluorine pump will transport the low refrigerant liquid multiple times of the evaporation capacity to the terminal evaporator in each storage room. Part of the liquid would evaporate in the evaporator by absorbing the heat, the remaining liquid will return to the low storage recycling barrel with the air through the gas return pipe, then the gas and liquid will be separated, with the air sucked away by the compressor and the remaining liquid and new charged refrigerant liquid transported to the terminal evaporator by the fluorine pump for evaporation and recycling. Major advantages The evaporator possesses high heat exchange efficiency and good cooling effect. The circulation volume of the refrigerant liquid is multiple times of the evaporation volume of the terminal, which guarantees a sufficient wetting perimeter to the heat exchange pipe and improves the heat exchange effect of the evaporator. Turbulent condition exists in the heat exchange pipe of the liquid refrigerant evaporator, and the heat exchange pipe wall is not easy to form oil film and its bottom is not easy to store up oil, which would benefit the heat exchange effect. So, with the same evaporative area, the heat exchange efficiency of fluorine pump liquid supply is higher than that of the direct expansion liquid supply by 25%. Long distance liquid supply is guaranteed. By employing the mechanical action of the fluorine pump and overcoming part of the resistance loss in the system, the long distance can be realized. The system is easy to operate and convenient for centralized control and automation, and the operation condition of the refrigerating compressor have been improved. Hot fluorine defrosting is easy to operate. In the fluorine pump liquid supply refrigerating system, the remaining liquid in the evaporator can directly discharged to low pressure storage recycling barrel in defrosting, and after the defrosting, turn on the fluorine pump to resume the liquid supply of the evaporator. It is very fast to return to the normal and easy to operate. 24
