-12C low temperature water cooled screw chiller for chemical industry 200KW industrial chiller
A -12°C low temperature water-cooled screw chiller is specifically designed for applications in the chemical industry that require a cooling capacity of 200 kW. This type of chiller is ideal for maintaining a stable and efficient cooling process in environments where precise temperature control is essential.
The chiller utilizes a water-cooled system, which means that it relies on a constant water supply to dissipate heat generated during the cooling process. This is achieved through the use of a water-cooled condenser, where the hot refrigerant gas is condensed into a liquid state by exchanging heat with the water flowing through the condenser pipes.
The chiller is equipped with a screw compressor, which is known for its efficiency and reliability in industrial applications. The screw compressor compresses the refrigerant gas, raising its temperature and pressure, and then sends it to the condenser for cooling.
To ensure efficient and reliable operation in the chemical industry, the chiller is designed with an anti-corrosion evaporator made of nickel white copper. This material is resistant to corrosion, making it suitable for handling the chemicals present in the cooling process.
The low temperature capability of -12°C makes this chiller suitable for a wide range of applications in the chemical industry, such as cooling processes involved in the production of chemicals, pharmaceuticals, or plastics. The precise temperature control provided by the chiller ensures that the desired temperature is maintained consistently, resulting in high-quality products and improved process efficiency.
Overall, the -12°C low temperature water-cooled screw chiller with an anti-corrosion evaporator is an excellent choice for industries requiring reliable and efficient cooling solutions in challenging chemical environments.
The working principle of a low-temperature water-cooled screw chiller is as follows:
Refrigeration Cycle: The chiller operates based on the vapor compression refrigeration cycle. It uses a refrigerant, typically R404A or R22, which undergoes phase changes between a high-pressure gas and a low-pressure liquid to absorb heat from the process fluid.
Compressor: The chiller contains a screw compressor, which is the heart of the system. The compressor compresses the refrigerant vapor, increasing its pressure and temperature.
Condenser: The high-pressure, high-temperature refrigerant vapor then flows into the condenser. In the water-cooled system, the condenser is cooled by water that circulates through the condenser coils. As the refrigerant gives off heat, it condenses into a high-pressure liquid.
Expansion Valve: The high-pressure liquid refrigerant passes through an expansion valve, where its pressure is reduced. This results in a drop in temperature and the refrigerant changes into a low-pressure, low-temperature mixture of liquid and vapor.
Evaporator: The low-pressure refrigerant mixture enters the evaporator, which is in contact with the process fluid that needs to be cooled. Heat is transferred from the process fluid to the refrigerant, causing the refrigerant to evaporate. This absorbs heat from the process fluid and cools it down.
Refrigerant Return: The refrigerant vapor is then drawn back into the compressor to start the cycle again. The process fluid, now cooled, continues its flow to the desired application or process.
Overall, the low-temperature water-cooled screw chiller uses the principles of refrigeration to remove heat from the process fluid and maintain the desired low temperature. The continuous circulation of the refrigerant allows for efficient cooling and temperature control.
