HY-WS Water-cooled Screw Type Chiller with Custom Explosion-proof and Acid-resistant Features（60HP~1000HP）
1. Introduction?
Our water - cooled screw chiller is a high - performance cooling device designed to meet the diverse needs of various industries. With the ability to be customized for explosion - proof and acid - resistant applications, it offers reliable and efficient cooling solutions in challenging environments.?
2. Working Principle?
The chiller operates based on a vapor - compression refrigeration cycle. A semi - hermetic screw compressor is at the heart of the system. It sucks in low - temperature, low - pressure refrigerant vapor from the evaporator. As the compressor runs, it compresses the refrigerant vapor, raising its pressure and temperature.?
The high - pressure, high - temperature refrigerant gas then enters the shell - and - tube condenser. Here, it exchanges heat with the cooling water flowing through the condenser. The refrigerant releases heat to the cooling water and condenses into a high - pressure liquid.?
The high - pressure liquid refrigerant passes through a drying filter to remove any moisture and impurities, and then through a thermal expansion valve. The expansion valve throttles the refrigerant, reducing its pressure and temperature as it enters the shell - and - tube evaporator.?
In the evaporator, the low - pressure refrigerant liquid absorbs heat from the chilled water flowing through the evaporator, causing the refrigerant to evaporate back into a vapor. The chilled water is thus cooled down to the desired temperature and is circulated to the process or space that requires cooling. The cycle then repeats continuously to maintain the cooling effect.?
Product Description:
Customizable with acid-resistant and corrosion-proof features, variable frequency capabilities, and explosion-proof design. Featuring selected original imported semi-hermetic screw compressors and semi-closed reciprocating compressors. Offering excellent performance and low noise levels. Based on customer requirements and tonnage of refrigeration, single-unit or multi-unit configurations are available. The compressors can automatically alternate operation according to load changes, balancing the operating hours of each compressor, thereby significantly extending the service life of the chilled water unit.
Features & Functions:
Compressor
Compressor selection BITZER (Bitzer) HANBELL (Hanbell) Refcomp (Levin Beverly) imported famous brand semi-hermetic screw compressors, 5:6 ultra-efficient screw rotor design than most compressor energy efficiency high 20-30%, with as smooth and reliable operation, high efficiency, low failure rate, easy maintenance, etc. For the unit to run all or part of the load, each compressor can be step less or 75%-100% of multi-stage capacity control.
Semi-hermetic screw compressors for R22, R407c, R134a and other refrigerant working fluid type.
Shell And Tube Condenser And Evaporator
Condenser heat transfer from Germany, Japan imported and domestically produced different types of bras, brass outer surface processed int trapezoidal low fin tube, increasing the heat transfer area and enhanced heat transfer performance. Bras inner surface is smooth, so that the pressure decreases, and the ease of cleaning and maintenance.
Evaporator efficiency heat ex-changer with internal thread brass, brass outer surface the spiral smooth as well as the water side baffles non-short-circuit design, chilled water the mixed heat ex-changer efficiency.
Refrigeration Accessories
Frozen Accessories selection of the world's most well-known brands Danfoss (Danfos) ALCO (Viagra), SPORLAN (Sporlan), quality, performance.
Electric Control Systems
Electronic control system with high intelligence PLC, PC-class microcomputer control system. Responsive, precise control, with automatic loading and unloading, the multiple functions of the timer switch and record the cause of the malfunction can be remote or central monitoring.
Stable and Reliable Operation: The robust construction and advanced design of the screw compressors ensure stable operation over long periods. They can handle a wide range of operating conditions, reducing the risk of breakdowns and maintenance requirements.
Low Noise and Vibration: The design of the screw compressors results in low noise and vibration levels. This is beneficial not only for a quieter working environment but also for reducing wear and tear on the chiller's components, thus extending its lifespan.
High Energy Efficiency: Compared to traditional scroll compressors, our screw compressors can achieve energy savings of over 20%. They feature stepless capacity control, allowing the compressor to continuously adjust its cooling capacity in the range of 25% - 100% according to the actual cooling load. This ensures precise control of energy output and efficient operation, especially during partial - load conditions.
