Product Description

Air Cooled Water Chiller

The Air Cooled Water Chiller, also recognized as an air-cooled box-type industrial chiller unit, employs an innovative air-cooling heat dissipation design. This system draws ambient air into the unit through integrated fans and expels heat through a condenser, effectively reducing the overall system temperature. Unlike its counterparts, it eliminates the need for an additional water cooling system, making installation and maintenance relatively straightforward.
Designed for locations with space constraints or inadequate cooling water supply, the Air Cooled Chiller offers practical solutions. However, its cooling efficiency is influenced by ambient temperature and humidity, rendering it particularly suitable for applications with lower heat loads. Each model comes equipped with an array of safety features, including motor overload protection, phase loss and phase reversal alarms, anti-freeze thermostats, pressure gauges, and more. These safety measures contribute to the chiller units’ exceptional performance and extended lifespan.
Throughout its operational cycle, the Air Cooled Water Chiller follows a series of steps rooted in the fundamental principles of heat exchange. This precision in temperature control, ranging from 3°C to 50°C, makes it a pivotal player in modern industrial sectors that demand accurate temperature regulation. Its adaptability and simplicity, combined with the absence of an additional water resource requirement, position it favorably in environments with limited space.
However, it’s essential to note that the cooling efficiency may be affected by the surrounding environmental conditions. In low-heat-load applications, these chillers stand out due to their superior performance and prolonged operational life.
In conclusion, the Air Cooled Water Chiller plays a crucial role in modern industries, offering reliable cooling technology and advanced control systems. Its contribution to precise temperature management propels progress and development in the industrial sector, emphasizing its significance as an indispensable asset in various applications.

Working Principle

Initiation Phase: Upon commencement, the air-cooled chiller begins its cycle by allowing the refrigerant to absorb heat from the target object within the evaporator, leading to vaporization.

Compression Cycle: Simultaneously, the compressor diligently extracts the resulting gas from the evaporator, compressing it into a state of high-temperature, high-pressure vapor.

Critical Heat Exchange: The high-pressure vaporized refrigerant is then directed to the condenser, engaging in a pivotal heat exchange with ambient air. During this process, heat is released, causing the vapor to condense into a liquid state.

Cyclical Transformation: Following condensation, the liquid refrigerant undergoes controlled depressurization through the expansion valve. Subsequently, it re-enters the evaporator, where it once again vaporizes, absorbing heat from the cooled object.

This intricate heat exchange dance persists until the industrial water attains the desired temperature. The air-cooled chiller’s efficacy lies in its ability to orchestrate this repetitive and precise sequence of evaporation, compression, heat exchange, and condensation, ultimately delivering optimal cooling results.

Application Industry

Chillers find widespread application across diverse industrial sectors, including plastics, electronics manufacturing, electroplating, pharmaceuticals, chemical engineering, ultrasonic cooling, and printing. Their role is pivotal in enhancing operational efficiency and product quality in various ways.
In the realm of plastics, chillers play a crucial role in the cooling of molds for plastic processing machinery. This contribution results in a notable improvement in the surface smoothness of plastic products, a reduction in surface flaws and internal stress, and a prevention of shrinkage and deformation. Moreover, chillers facilitate mold release, accelerate product shaping, and overall contribute significantly to elevating the production efficiency and product quality of plastic molding machines.
The electronics manufacturing industry benefits from the precise temperature control offered by chillers, ensuring optimal conditions for intricate electronic components’ production. In electroplating, chillers contribute to maintaining consistent temperatures critical for achieving high-quality plating finishes. In pharmaceuticals and chemical engineering, these cooling systems prove indispensable in various processes, safeguarding product integrity and quality.
Furthermore, chillers find application in ultrasonic cooling, a process vital in industries where precision cooling is essential. The printing industry relies on chillers to regulate temperatures during printing processes, ensuring the quality and reliability of the final printed products.
In essence, the versatile applications of chillers underscore their indispensable role in maintaining optimal temperatures across a spectrum of industrial processes, ultimately contributing to enhanced production outcomes and product excellence.

Product Highlights:

Scroll Compressor
Our range of air-cooled chillers exclusively employs scroll compressors, positioning the compressor as the central component in the entire refrigerant cycle system. Embracing a dual-flex design, the scroll compressor ensures a tight seal between the scroll discs. This innovative design allows radial and axial separation of the scroll discs, enabling the passage of debris or liquid without causing harm to the compressor. The outcome is a prolonged compressor lifespan, heightened reliability, improved liquid tolerance, and enhanced impurity resistance.

Shell and Tube Evaporator

The air-cooled chiller incorporates a shell and tube evaporator design. In this system, the refrigerant undergoes evaporation within the heat exchange tubes, while water circulates on the outer shell. To optimize heat exchange efficiency, a 2mm thick baffle plate is strategically placed on the shell side, inducing a back-and-forth flow of water, creating an ice brine. Moreover, to ensure a consistent operating temperature, the exterior shell of the evaporator is insulated.

For the heat exchange tubes, we utilize high-efficiency seamless copper tubes. These tubes undergo a grooving process to create internal thread fins, effectively increasing the heat exchange surface area with the refrigerant. This technological advancement doubles the heat transfer area, thereby significantly enhancing overall heat transfer efficiency.

Finned Type Condenser

The air-cooled chiller employs a high-efficiency copper tube with an aluminum-finned condenser, effectively dissipating heat. The finned structure enhances the heat exchange surface area between the condenser and the surrounding environment, thereby improving overall heat dissipation efficiency. The exceptional thermal conductivity of copper tubes, coupled with the efficient heat dissipation characteristics of aluminum fins, ensures high efficiency throughout the cooling process.

Furthermore, the incorporation of light water aluminum and blue aluminum foils adds an additional protective layer. These foils play a crucial role in preventing corrosion of the copper tubes, particularly in corrosive environments, thereby extending the condenser’s lifespan and maintaining optimal refrigeration performance.
