Working Principle

When the air cooled chiller starts, the refrigerant absorbs the heat from the cooled object in the evaporator and vaporizes. The compressor continuously extracts the generated gas from the evaporator and compresses it into high-temperature, high-pressure vapor. The refrigerant vapor is then sent to the condenser, where it undergoes heat exchange with the air. After releasing heat, it condenses into a liquid. The liquid refrigerant, after being depressurized by the expansion valve, enters the evaporator where it vaporizes again, absorbing heat from the cooled object. This heat exchange process is repeated until the industrial water is cooled to the desired temperature.

 Highlights of the Product

Scroll Compressor

The entire range of Xiecheng air cooled chillers utilizes scroll compressors. The compressor serves as the heart of the entire refrigerant cycle system. The scroll compressor adopts a dual-flex design, ensuring tight sealing between the scroll discs. This design allows the scroll discs to separate radially and axially, allowing debris or liquid to pass through without damaging the compressor. This results in increased compressor lifespan, enhanced reliability, better liquid tolerance, and improved tolerance for impurities.

Characteristics of the compressor:

 Shell and Tube Evaporator

The air cooled chiller utilizes a shell and tube evaporator. In this system, the refrigerant evaporates inside the heat exchange tubes, while water flows on the shell side. To enhance the heat exchange efficiency, a 2mm thick baffle plate is installed on the shell side, causing the water to flow back and forth to create ice brine. Additionally, to maintain a stable operating temperature, the exterior shell of the evaporator is covered with insulation material.

For the heat exchange tubes, we employ high-efficiency seamless copper tubes. These tubes undergo a grooving process to form internal thread fins, thereby increasing the heat exchange surface area with the refrigerant. With this technology, the heat transfer area is doubled, significantly improving the heat transfer efficiency.

 Finned Type Condenser

By adopting a high-efficiency copper tube with aluminum finned type condenser, the air cooled chiller effectively dissipates heat. The finned structure increases the heat exchange surface area between the condenser and the surrounding environment, improving the heat dissipation efficiency. The excellent thermal conductivity of copper tubes, combined with the efficient heat dissipation characteristics of aluminum fins, ensures high efficiency during the cooling process.

Additionally, the application of light water aluminum and blue aluminum foils provides an additional protective layer. They help prevent corrosion of the copper tubes in corrosive environments, thereby extending the lifespan of the condenser and maintaining optimal refrigeration performance.

 Product Details

 

Microcomputer Controller

 

 

The air cooled chiller features an industry-leading LCD display microcomputer controller. This controller provides simultaneous display of the chiller's outlet temperature and the set temperature for precise temperature control. The user-friendly interface allows for easy operation and adjustment. With this controller, the water temperature can be precisely controlled within a range of 3°C to 50°C, ensuring optimal cooling performance.

 

 

 

 

 

 

Drying Filter System

 

The air cooled chiller is equipped with Emerson filters, which effectively remove impurities from the refrigerant and absorb free moisture in fluorocarbons. This system prevents the formation of ice blockages, particularly in narrow sections of pipelines (especially the valve ports of thermal expansion valves). It ensures the purity of the refrigerant and protects the compressor from potential damage.

 

 

 

 

Efficient Cooling System

 

 

The air-cooled chiller is equipped with a high-efficiency cooling system that includes low-noise external rotor fans. These fans are specifically designed to accelerate heat dissipation and enhance the overall cooling efficiency of the system. By improving airflow and maximizing heat transfer, this system ensures optimal cooling performance while operating with minimal noise levels.

 

High and Low Pressure Protection System

 

The high and low pressure protection system is designed to enhance the safety and efficiency of water pump operations. It involves the installation of high and low pressure gauges as well as a pump pressure gauge to continuously monitor the pressure of the water pump during operation.

 

Water Pumps

 

 

For chiller models ranging from 1 to 6HP, Orank stainless steel pump heads are used. For models with 8HP or higher, Taiwan Yuanli pipeline pumps are employed. These water pumps are known for their low noise operation, leak-free performance, and maintenance-free characteristics. They ensure reliable and efficient water circulation within the chiller system.

 

Electrical Self-control System

 

The electrical self-control system consists of power supply and automatic control components. It utilizes Siemens electronic components to ensure stable operation of the equipment. It incorporates a comprehensive range of safety protection devices, including current overload protection, high and low-pressure protection systems, and electronic time delay. These safety features provide robust protection and are complemented by an intuitive display system that alerts users to any abnormalities.
