240RT air cooled screw chiller supplier price

An air-cooled screw chiller is an industrial refrigeration device that uses air as the cooling medium and a screw compressor as its core power component. Its primary function is to cool water (or other refrigerant) to a specific temperature (typically 5-15°C) through a circulation system. The refrigerant then delivers the cooling energy to the production process, equipment, or space requiring cooling, ultimately achieving temperature control, heat dissipation, or cooling. It is a core component of industrial refrigeration and large-scale commercial air conditioning. Its high cooling capacity, high efficiency, and stable operation have made it a widespread replacement for traditional small and medium-sized refrigeration equipment.

Working Principle
Air-cooled screw chillers operate based on the refrigeration cycle. The gaseous refrigerant from the evaporator is adiabatically compressed by the compressor, reaching a high-temperature, high-pressure state. It is then cooled and condensed into a liquid state in the condenser at an equal pressure. It then expands to a low-pressure state through a throttle valve, forming a gas-liquid mixture. The low-temperature, low-pressure liquid refrigerant absorbs heat from the material being cooled in the evaporator, returning to a gaseous state and entering the compressor again to begin the cycle anew.

01 Semi-hermetic Compressors

▪ Adopted world famous branded semi-hermetic compressors for long term reliable and efficient running; ▪ Compressor runs with no stage limits to realize stageless continuous adjustment of cooling capacity in between 25%-100% power loaded and maintaining stable outputs; ▪ Option: HANBELL, BITZER                                                                             

02 AIr cooled high-efficient inner threaded copper-tubing hydrophilic aluminum foil fin type Evaporator

The condenser type is hydrophilic aluminum foil fin type. The aluminum foil is hydrophilic treated. Through special processing, a hydrophilic layer is coated on the surface. The condensed water will spread quickly on the hydrophilic aluminum foil and will not condense into water droplets. Increase the heat exchange area, speed up the cooling and heating speed, and effectively avoid the noise caused by condensed water blocking the air flow.

 hydrophilic aluminum foil fin type Evaporator

The raw material of the heat exchanger is hydrophilic aluminum foil, which can increase the refrigeration efficiency by 5%. It is also anti-corrosion and anti-mold, has no odor, and will not cause the accumulation of water droplets to block the heat exchange.

03 Shell and Tube Evaporator

shell and tube type evaporator adopts inner treaded copper design, with larger heat exchanging area for higher efficiency and maximizing system performance.

06 Thermal expansion valve

The imported thermal expansion valve is used to throttle and cool the high-pressure super cooled liquid into a low-temperature and low-pressure liquid, and automatically adjust the flow rate of the refrigerant into the evaporator according to the evaporation temperature, and maintain a certain pressure to ensure evaporation in the evaporator. rate.

 

07 Electrical control system

The control panel is an LCD touch screen, highly automated, easy to operate, intuitive interface, which can make the unit to continuously adjust the performance energy between 25% and 100% (or stepless energy adjustment) to ensure the complete performance of the compressor Play and help users save operating costs to the greatest extent. The control panel interface has two languages, Chinese and English.
