The main design features of brine low temperature screw unit (4 ° C ~ -50 ° C):
1. It adopts imported high-efficiency economizer semi-closed reciprocating piston & twin-screw compressor, which has high energy efficiency, and is equipped with high-quality and high-efficiency copper tube to make condenser, evaporator and world famous brand control components, so that the unit has small volume and low noise. High energy, long life, easy operation and stability.
2. Independent refrigeration system design, multi-head unit is relatively independent, the moving parts are minimized and the operation is reliable.
3. Under the minimum load (25%) of each refrigeration system compressor, the star-to-turn triangle step-down starts, effectively reducing the starting current and the impact on the power grid.
4. Flexible design can make the unit's continuous energy adjustment between 25% and 100% (stepless energy adjustment), ensuring the full performance of the compressor and helping users to maximize operating costs.
5. Adopting Siemens microcomputer programmable controller control, combined with compressor sectional energy adjustment or stepless energy adjustment system, it can timely and accurately control the matching between cooling capacity and cooling load of the machine to ensure the highest operating efficiency of the unit and reduce energy consumption. Reliable energy-saving operation.
6. A variety of brines can be selected according to the needs of users, such as glycol aqueous solution, alcohol, ternary mixed solution (40% ethylene glycol, 40% water, 20% ethanol) and other alcohol-based coolants. The evaporator can be designed according to the anti-corrosion requirements, and the calcium chloride salt aqueous solution is used as the brine.
7. The application of economizer technology increases the gas transmission coefficient of the compressor, thereby increasing the efficiency and energy efficiency ratio of the compressor.
8. The use of the secondary oil separator minimizes the lubricating oil entering the evaporator and improves the heat exchange efficiency of the evaporator, which not only improves the cooling efficiency, but also improves the reliability of the product operation.
