HJL-WSZ series water-cooled screw integrated chiller unit
characteristic:
Compressor: Selected original imported branded semi enclosed screw and semi enclosed reciprocating compressors. Good performance and low noise. According to customer needs and the size of the cooling capacity, single or multiple machine combinations can be used. The compressor can automatically alternate operation according to load changes, balancing the operating hours of each compressor and greatly extending the service life of the chiller unit.
Evaporator: The copper tube of the evaporator adopts an internally and externally threaded reinforced tube. The surface of the copper tube has threads, the outer surface of the copper tube is smooth, and the cooling effect is good. The evaporator cylinder is insulated with a 25mm thick PE insulation board, which does not condense and reduces the loss of cooling capacity.
Condenser: The condenser uses copper pipes imported from foreign countries and processed into trapezoidal low assist pipes to enhance heat transfer capacity. The surface of the copper tube is smooth, reducing water pressure and making it easy to clean and maintain.
Protection device: The protection system includes temperature control switch, antifreeze switch, fusible plug, high and low pressure switch, overload protector, compressor overheat protector, compressor frequent start protector, and abnormal indicator light. Control System: The company has developed a highly intelligent PLC and PC level computer control system, which can be used for remote monitoring and control. It is easy to operate and the host is connected to the power supply. Low failure rate, high safety factor, and simple installation. The system control can be adjusted in real-time, intuitive and reliable.
Note: The whole machine can be customized according to process requirements, including explosion-proof chillers, acid resistant chillers, stainless steel food grade chillers, integrated chillers, etc. It supports foreign 60Hz-420v-480V voltage standards.
Overview of Integrated Chiller Unit: The integrated chiller unit integrates water-cooled units, machine room civil engineering, cooling towers, cooling pumps, cooling water pipelines, valves, instruments, and measurement and control devices. It has the advantages of small size, high efficiency, low noise, long service life, easy operation, and high efficiency and energy saving. The refrigerant condensation heat of the dual high-efficiency integrated chiller unit is carried away by the latent heat of evaporation of water, and its condensation temperature is 5-8 ℃ lower than that of the water-cooled unit and 10-15 ℃ lower than that of the air-cooled unit. For every 1 ℃ increase in condensation temperature, the energy consumption of the unit will increase by about 1.9%, while the cooling capacity will decrease by about 1.1%. Therefore, integrated chillers are energy-saving due to their low condensing temperature.

Characteristics of integrated chiller unit: ① The refrigerant condensation heat of the dual high-efficiency integrated chiller unit is carried away by the latent heat of water evaporation, and its condensation temperature is 5-8 ℃ lower than that of the water-cooled unit and 10-15 ℃ lower than that of the air-cooled unit. For every 1 ℃ increase in condensation temperature, the energy consumption of the unit will increase by about 1.9%, while the cooling capacity will decrease by about 1.1%. Therefore, integrated chillers are energy-saving due to their low condensing temperature.
② The integrated chiller unit adopts an evaporative condenser, which integrates the shell and tube condenser, cooling tower, circulating water tank, circulating water pump, and water treatment device into one, which can minimize the installation workload and reduce the total investment compared to using other condensation methods.
③ Low power consumption, low water loss rate, efficient and energy-saving.
④ Adopting the ultra thick integral hot-dip galvanizing process, the shell is a double-layer insulation sleeve type, and the panels are all made of anti-corrosion materials. The equipment does not require maintenance, so the operating cost is low.
⑤ Two compressor options: screw compressor with unloading energy control device, which can achieve multi-stage or stepless energy regulation; The fully enclosed vortex refrigeration compressor has the advantages of high efficiency, low noise, small vibration, reliable operation, and long service life.
⑥ The microcomputer control system has powerful functions such as safety protection, communication, fault diagnosis, and automatic adaptation.
⑦ The shell and tube evaporator adopts high-efficiency copper tubes with internal threads, combined with unique optimized design, which has the advantages of good heat transfer effect, reliable oil return, and easy maintenance.
⑧ The evaporative condenser adopts elliptical coils, which increases the surface area of the coil tubes and enhances the air and water flow characteristics outside the spaced tube coils, thereby improving heat transfer efficiency. It has low water consumption rate, corrosion resistance, small footprint, and easy maintenance and installation.
