1. Match with famous brand high quality and efficient compressor
The main engine adopts the semi closed screw compressor of famous brand. Compared with the piston compressor, the semi closed screw compressor has the following advantages:
① It has few parts (about 1 / 3 of the piston compressor), simple structure, few wearing parts, high reliability and long service life;
② The compressor has the advantages of uniform and continuous suction and exhaust, low exhaust temperature, small vibration, insensitivity to wet compression and strong resistance to liquid hammer;
2. Dry shell and tube evaporator with high efficiency heat exchange tube
① Using the most advanced DAE high efficiency evaporation heat transfer tube, the inner surface of the tube has multiple spiral ribs and spiral protrusions, which greatly improves the heat transfer coefficient and heat transfer capacity.
② The internal structure of the evaporator is optimized and a high-efficiency homogenizer is arranged to solve the problem of uniformity of refrigerant distribution in the system.
③ The sealing structure of the baffle plate is improved, the leakage of the baffle plate is solved, and the heat exchange efficiency of the evaporator is greatly improved, so as to ensure the high performance level of the unit.
3. Shell and tube water cooled condenser with high efficiency heat exchange tube
① The most advanced DAE high efficiency condensing heat transfer tube is adopted, with multiple helical ribs and helical protrusions on the outer surface of the tube, which greatly improves the heat transfer coefficient and heat transfer capacity.
② The optimization design of the internal structure greatly improves the ability of the condenser to resist corrosion and dirt, and gives full play to the heat exchange effect of the condenser, so as to ensure that the unit reaches a high level of performance.
③ Safety valve and vent valve are also installed on the shell and tube condenser to ensure the safety of the shell and tube condenser and the convenience of cleaning and maintenance.
