Working Principle

A water-cooled chiller utilizes a shell and tube evaporator to facilitate heat exchange between water and refrigerant. The refrigerant system absorbs the heat load from the water, causing the water to cool and generate chilled water. The heat absorbed by the refrigerant is then transported to the shell and tube condenser through the action of the compressor. Heat exchange occurs between the refrigerant and water, allowing the water to absorb the heat. Finally, the heat is dissipated to the external cooling tower through water pipes, which is known as water cooling.

 Highlights of the Product

Scroll Compressor

The entire range of Xiecheng water 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 water 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.

 Shell and Tube Condenser

Water Cooled Chiller utilizes a shell and tube condenser, with the internal copper tubes employing an outer thread embossing process. This design effectively enhances the heat exchange efficiency between the refrigerant and water during the process. Compared to traditional smooth copper tubes, the outer thread embossing process increases the surface area of the copper tubes, thereby expanding the contact area for heat exchange and improving the thermal conductivity of the condenser. This optimization design allows the condenser of the water-cooled chiller to transfer heat from the refrigerant to the water more rapidly and consistently, enabling the water to carry away the heat.

 Product Details

Microcomputer Controller

The water 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 water 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.

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.
