Audited Supplier -5 degree low temperature screw chiller price Industrial use Glycol water cooled chiller manufacturer
What is a glycol chiller ?
A glycol chiller, also known as a glycol cooling system, is a type of refrigeration equipment designed to cool or maintain the temperature of liquids through the circulation of a glycol/water mixture. Glycol chillers are commonly used in various industrial processes, such as breweries, wineries, food processing plants, chemical plants, pharmaceutical facilities, and HVAC systems.
Glycol chiller is a type of low temperature, we have air cooled glycol chiller, water cooled glycol chiller, scroll compressor glycol chiller, screw compressor glycol chiller, and piston glycol chiller. When you need a glycol chiller please feel free to contact oumalchiler to get the glycol chiller price.
Glycol chillers work on the principle of heat exchange. The chiller unit consists of a compressor, condenser, evaporator, expansion valve, and a pump. The primary refrigerant used in glycol chillers is typically a mixture of water and ethylene or propylene glycol. This mixture, known as the glycol solution, has a lower freezing point than water, allowing it to maintain lower temperatures.
The process begins with the compressor, which compresses the refrigerant vapor, raising its pressure and temperature. The hot refrigerant vapor then flows into the condenser where it releases heat to the surrounding environment and condenses into a high-pressure liquid.
The high-pressure liquid passes through the expansion valve, which reduces its pressure and temperature. As it expands, it absorbs heat from the glycol/water mixture circulating in the evaporator.
The chilled glycol solution is pumped through the system and comes into contact with the evaporator's tubes or plates. Heat from the liquid is transferred to the refrigerant, causing the glycol to cool down. The cooled glycol is then circulated through pipes or coils to the target application, where it absorbs heat and maintains the desired temperature. Afterward, the warm glycol returns to the chiller to be cooled again.
The chilled glycol solution can be used to cool various processes or equipment by circulating it through heat exchangers or directly flowing it through the process equipment. This allows precise temperature control and helps maintain stable conditions for critical applications.
Overall, glycol chillers provide efficient and reliable cooling for a wide range of industrial applications, enabling precise temperature control necessary for many industrial processes.
A low temperature water-cooled screw chiller is a refrigeration system designed to provide cooling for industrial processes or applications that require low temperatures. It typically consists of the following features:
Screw Compressor: The chiller utilizes a screw compressor which is highly efficient and capable of handling low temperature requirements. The screw compressor provides reliable and stable performance even at low temperatures.
Water-Cooled Condenser: The chiller is equipped with a water-cooled condenser that efficiently removes heat from the refrigerant. Water from an external source, such as a cooling tower or a closed-loop water circuit, is used to cool the condenser.
Refrigeration Circuit: The chiller's refrigeration circuit includes the evaporator, condenser, expansion valve, and compressor. The refrigerant circulates through these components, absorbing heat from the process and releasing it to the cooling water in the condenser.
Low Temperature Operation: The chiller is designed to achieve and maintain low temperatures, typically ranging from -40°C to -10°C (-40°F to 14°F). It is suitable for applications requiring precise and stable temperature control at extreme low temperatures.
Advanced Control System: The chiller is equipped with an advanced control system that allows precise temperature regulation and monitoring. It provides automated operation, fault diagnosis, and safety features to ensure efficient and reliable performance.
Corrosion Protection: As seawater can be corrosive, a seawater water-cooled screw chiller is designed with corrosion-resistant materials and coatings to withstand the corrosive effects of saltwater. This extends the lifespan of the chiller in marine or coastal environments.
Energy Efficiency: Low temperature water-cooled screw chillers are optimized for energy efficiency. They are equipped with energy-saving features such as variable speed compressors, heat recovery capabilities, and efficient heat exchange designs, reducing overall energy consumption and operating costs.
Customization Options: These chillers can be tailored to specific requirements with options for capacity, control systems, safety features, and integration with other equipment or processes.
The application of a low temperature water-cooled screw chiller includes various industries such as chemical processing, pharmaceuticals, food and beverage production, cold storage, laboratory testing, and other applications where precise and stable low-temperature cooling is required.
The working principle of the water cooled screw chiller is: When the unit is refrigerated, the compressor sucks the low-temperature and low-pressure refrigerant in the evaporator into the cylinder. After the compressor performs work, the refrigerant vapor is compressed into high-temperature and high-pressure gas.
Enter the condenser through the exhaust pipe. The high-temperature and high-pressure refrigerant gas exchanges heat with the cooling water in the condenser, and transfers the heat to the cooling water, while the refrigerant gas is condensed into a high-pressure liquid. The high-pressure liquid from the condenser enters the evaporator after being throttled and pressure-reduced by the thermal expansion valve. In the evaporator, the low-pressure liquid refrigerant absorbs the heat of the chilled water and vaporizes, so that the chilled water is cooled down and becomes the required low-temperature water. The vaporized refrigerant gas is sucked in by the compressor again for compression, and discharged into the condenser, so that it goes round and round, and circulates continuously, so as to realize the cooling of the chilled water.
The chilled water from the unit enters the indoor fan coils, variable air volume air conditioners and other terminal devices, and exchanges heat with convection air indoors. In this process, the water absorbs the heat of the indoor air (dissipates heat to the indoor air). While the temperature rises, the indoor air temperature drops after passing through the indoor heat exchanger, and is driven by the fan to send it into the room, thereby reducing the indoor air temperature, and the chilled water after the temperature rises reenters the unit under the action of the water pump. Circulation, so as to achieve the purpose of continuous refrigeration.
