air cooling water chiller with shell and tube evaporator

Structure for air cooling water chiller with shell and tube evaporator

• 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 air cooling water chiller with shell and tube evaporator
• 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.

Features for air cooling water chiller with shell and tube evaporator

• Compact and Flexible: Without the need for a separate cooling tower and related piping systems like water - cooled chillers, air - cooled chillers have a more compact structure and are easier to install and move. Some models are equipped with casters, allowing them to be easily relocated within the factory area.
• Wide Temperature Control Range: The standard temperature control range is usually 5℃ - 35℃, and some non - standard models can be customized to achieve ultra - low temperatures down to - 50℃.
• High Heat Exchange Efficiency: The shell and tube evaporator has a large heat exchange area, which can effectively transfer heat between the refrigerant and the coolant, ensuring the efficient operation of the chiller.
• Reliable Safety Protection: Equipped with a comprehensive safety protection system, including high and low - pressure protection for the refrigeration system, overload protection for the compressor, phase - loss and voltage - abnormal protection for the power supply, and freeze protection and water - flow protection for the water system.

Applications for air cooling water chiller with shell and tube evaporator

• Plastic Processing Industry: Used to cool injection molding machines, extruders, and other equipment to prevent plastic materials from overheating during processing, improve product quality, and shorten the production cycle.
• Electronics Manufacturing: Cool electronic components and equipment, such as semiconductor manufacturing equipment, servers, etc., to ensure their stable operation and prevent damage caused by overheating.
• Chemical Industry: In chemical production processes, it is used to cool reactors, condensers, and other equipment to control reaction temperatures and ensure the safety and quality of chemical reactions.
• Food and Beverage Industry: Applied to cool food processing equipment, such as refrigeration cabinets, freezers, and pasteurization equipment, to maintain the freshness and quality of food and beverages.

Selection Considerations for air cooling water chiller with shell and tube evaporator

• Cooling Capacity: Calculate the required cooling capacity according to the cooling requirements of the actual production process to ensure that the chiller can meet the cooling needs.
• Energy Efficiency: Consider the energy - efficiency ratio of the chiller. A higher energy - efficiency ratio means lower energy consumption and operating costs.
• Temperature Control Accuracy: For processes with strict temperature requirements, choose a chiller with high - precision temperature control.
• Noise Level: In some environments where noise is restricted, such as in workshops close to office areas or residential areas, select a chiller with a lower noise level.
