The invention provides a flooded screw machine quick-freezing refrigerator unit, which includes a compressor, an evaporator, an external oil separator, a low-pressure circulation barrel, and a quick-freezing pipe assembly. The refrigerant outlet of the compressor is connected to an external oil separator The refrigerant inlet of the oil separator, the refrigerant outlet of the oil separator is connected to the inlet of the evaporator, the outlet of the evaporator is connected to the refrigerant inlet of the low-pressure circulation barrel, and the refrigerant outlet of the low-pressure circulation barrel is connected to the quick-freezing pipe assembly The refrigerant inlet of the quick-freezing pipe assembly is connected to the air inlet of the low-pressure circulation bucket, and the gas outlet of the low-pressure circulation bucket is connected to the refrigerant inlet of the compressor. The flooded screw machine quick-freezing refrigerator unit of the present invention absorbs the characteristics of ammonia refrigeration energy saving, good refrigeration effect and safety and convenience of freon, greatly improves the refrigeration efficiency of the system using freon as the refrigerant, the comprehensive energy efficiency ratio is significantly improved, and the energy consumption is greatly reduced , so that the cold storage unit of the present invention has extremely strong market competitiveness.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to a flooded screw machine quick-freezing refrigerator unit. Background technique [0002] At present, in the refrigeration industry, there are mainly Freon refrigeration and ammonia refrigeration in terms of refrigerants. Compared with Freon, ammonia has better refrigeration effect and high refrigeration efficiency, but ammonia refrigeration is less safe, while Freon is safe, reliable and convenient. Because the principles of the two refrigeration systems based on the two refrigerants are different and the equipment settings are different, they cannot be used in common use. Therefore, the existing quick-freezing cold storage units cannot simultaneously achieve two effects of energy saving and safety. [0003] Therefore, prior art still needs further improvement. Contents of the invention [0004] In view of the deficiencies in the prior art, the present invention is to pro...
