2017 wholesale price Pool Heat Pumps - Special water chiller for textile and chemical fibers – Sunvi Detail:

Application :
Textile and chemical fibre industry:
The main technological links of chiller
application are raw material slicing, drying, yellowing machine, mixer, dissolving machine, air static adjustment. It can accurately control the temperature of water and environment, improve the qualified rate of products and improve production efficiency.
1. World-renowned compressors: adopt world-renowned twin-screw compressor series, high efficiency 5:6 asymmetric screw tooth profile and advanced linear design, simple machine structure, only one tenth of the number of parts of piston compressor, less vulnerable parts, no suction and exhaust valves, no expansion process, large single-stage pressure ratio, insensitive to hydraulic shock. Built-in high-efficiency oil separator, the amount of oil brought out by exhaust is less than 1.5%. It can effectively improve the heat transfer efficiency of the two exchangers and save energy and durable. Efficient energy control to achieve 10%-100% load grading or stepless energy regulation. Through multi-head coordination and PLC control technology, the unit can achieve the best energy efficiency ratio at full load or partial load, and significantly reduce your operating costs.
2. Shell-and-tube condenser: using high-efficiency external threaded copper tubes, using the latest CAD/CAM design and processing technology, with CNC processing center production, corresponding to heat dissipation, water flow rate, scaling coefficient, calculating the effective heat transfer area, leaving 5-10% surplus; both end caps are easy to disassemble, easy to maintain;
3. Evaporator: Using U-type evaporator, high-efficiency inner-threaded heat exchanger tube and patent-designed spiral baffle to make water flow more uniform, overcome the defects of bow baffle, such as large flow resistance and pressure drop, flow dead zone, easy scaling, small average temperature difference of heat transfer, easy failure under vibration conditions, can reduce pressure drop by about 45%, and increase heat transfer coefficient by 20%-30%. Under the same heat load, the size of heat exchanger can be greatly reduced.
4. Full-liquid high-efficiency unit: advantages of using full-liquid evaporator:
A. Completely wetted heat transfer surfaces can increase the efficiency of evaporators.
Increase the low pressure side pressure of the system.
B. The liquid refrigerant boils on the shell side of the evaporator, and the pressure loss is small, and the temperature is relatively uniform. Because the vapor at the suction end enters the compressor in a nearly saturated state, the compression efficiency and mass flow rate of the compressor can be increased.
C. Small size, light weight and large refrigeration capacity can reduce energy consumption by 10%-15% compared with similar dry products, which fully reflects the high efficiency and energy saving of the unit.
5. Control system: industrial centralized control system, PIC controller, 7-inch touch screen, full Chinese operation interface, menu prompt easy to operate, can view the operation status of the unit at any time, adjust the working mode, accurately control the matching of refrigeration capacity and cooling load of the unit, ensure that the unit runs with the best efficiency and reduce operating costs. Internal integration of water flow, low temperature, high and low pressure, anti-freezing, reverse phase, delay start, overload, over-temperature, oil pressure difference and other security protection functions.
6. Accurate control can control the temperature in the range of (+1). It is easy to operate, safe and reliable.
7. The unit has beautiful appearance, neat layout, compact structure, small occupied area, and is convenient for inspection and maintenance.
