shell and tube evaporator kind industrial air cooled chiller

Structure for shell and tube evaporator kind industrial air cooled chiller

• Compressor: It is the core component that compresses the refrigerant gas to increase its pressure and temperature. Common types include scroll compressors and screw compressors. For example, some small - to - medium - sized chillers often use scroll compressors due to their advantages of low noise, stable operation, and high efficiency.
• Air - cooled Condenser: Usually composed of copper tubes and aluminum fins. The high - pressure, high - temperature refrigerant gas from the compressor releases heat to the ambient air through the finned tubes and condenses into a liquid.
• Shell and Tube Evaporator: Consists of a shell and a bundle of tubes. The refrigerant flows outside the tubes, and the coolant (such as water) flows inside the tubes. Heat exchange occurs between the refrigerant and the coolant, with the refrigerant absorbing heat from the coolant and evaporating into a gas.
• Expansion Valve: It is used to throttle and depressurize the liquid refrigerant. The high - pressure liquid refrigerant passes through the expansion valve and becomes a low - pressure liquid - gas mixture before entering the evaporator.
• Control System: Includes components such as a temperature controller, pressure sensor, and electrical control components, which are used to monitor and control the operation of the chiller, ensuring that the cooling temperature and system pressure are within the set range.

• Working Principle for shell and tube evaporator kind industrial air cooled chiller:
• The compressor compresses the refrigerant gas to increase its pressure and temperature. The high-pressure, high-temperature refrigerant gas then enters the air-cooled condenser, where it releases heat to the ambient air and condenses into a liquid. The liquid refrigerant passes through the expansion valve, undergoes throttling and depressurization, and then enters the shell and tube evaporator. In the evaporator, the refrigerant absorbs heat from the water inside the tubes, evaporates into a gas, and the cooled water is then sent to the user equipment for cooling.

shell and tube evaporator kind industrial air cooled chiller Features:

• No Cooling Tower Required: Unlike water-cooled chillers, air-cooled chillers do not need a cooling tower, which saves installation space and eliminates the need for cooling tower maintenance. They are suitable for areas with poor water quality or where water resources are scarce.
• Compact Design: They have a relatively compact structure and are easy to install and move. Some models are equipped with casters, which can be easily moved to different working positions.
• High Heat Exchange Efficiency: The shell and tube evaporator has a large heat exchange area and high heat transfer efficiency, which can ensure the stable operation of the chiller and the efficient cooling of the cooled medium.
• Wide Application Range: It can provide cooling water with a temperature range of 5℃ - 35℃, which is suitable for various industrial cooling applications, such as plastic processing, electronics manufacturing, chemical industry, and food processing.

• Plastic Industry: Used for cooling injection molding machines, extruders, and other equipment to improve the quality and production efficiency of plastic products.
• Electronics Manufacturing: Cool electronic components and equipment to ensure their stable operation and prevent overheating.
• Chemical Industry: Used for cooling reactors, condensers, and other equipment in the chemical production process to control the reaction temperature and ensure the safety and quality of the production process.
• Food and Beverage Processing: Cool food processing equipment, such as refrigeration cabinets, freezers, and pasteurization equipment, to ensure the quality and safety of food and beverages.

Selection Considerations of shell and tube evaporator kind industrial air cooled chiller

• Cooling Capacity: According to the cooling requirements of the user equipment, calculate the required cooling capacity to ensure that the chiller can provide sufficient cooling.
• Temperature Control Accuracy: For some processes that require high-precision temperature control, choose a chiller with high temperature control accuracy.
• Energy Efficiency: Consider the energy efficiency ratio of the chiller to reduce energy consumption and operating costs.
• Noise Level: In some noise-sensitive environments, choose a chiller with a low noise level.
