In industrial production, drying equipment plays a crucial role by removing moisture from materials to achieve the purpose of preserving, processing, or improving product quality. As an important auxiliary equipment in the drying system, the performance and stability of the chiller directly affect the efficiency and effectiveness of the drying process.

So, what are the specific requirements for chillers used in drying equipment? The following will delve into multiple aspects, including technical performance, environmental adaptability, energy efficiency ratio, maintenance convenience, safety, and intelligent management.

1 Technical performance requirements

1）Matching of cooling capacity

The primary task of a chiller is to provide stable and sufficient cooling water to meet the needs of drying equipment under different operating conditions. Therefore, its cooling capacity must match the heat load of the drying equipment, avoiding waste and preventing insufficient cooling. This requires the chiller to accurately calculate the heat load of the drying equipment during design and reserve a certain amount of adjustment space to cope with production fluctuations.

2）Temperature control accuracy

During the drying process, the material often has very strict temperature requirements for the cooling water. Excessive or insufficient temperature can affect the drying effect and even damage the material. Therefore, the chiller needs to have a high-precision temperature control system that can accurately control the outlet temperature and maintain stability within the set range, with the smaller the fluctuation range, the better.

3） Flow and pressure stability

In addition to temperature, the flow rate and pressure of cooling water are also key factors affecting the drying effect. The chiller should be able to ensure that the flow rate and pressure of the cooling water remain constant during long-term operation, avoiding uneven cooling or equipment failure caused by insufficient flow or pressure fluctuations.

2 Environmental adaptability requirements

1）Wide temperature range working ability

The industrial production environment is complex and ever-changing, and chillers need to have the ability to operate stably over a wide temperature range. Whether it’s high temperatures, scorching heat, or extremely cold winters, it can maintain efficient operation without being affected by external environmental temperatures.

2）Corrosion resistant and dust-proof design

In some special industries, such as chemical and pharmaceutical industries, chillers used in drying equipment also need to have corrosion-resistant and dust-proof designs. Select corrosion-resistant materials to manufacture key components such as heat exchangers, pipelines, etc., and strengthen the sealing of the equipment to prevent corrosive gases or dust from entering, ensuring long-term stable operation of the equipment.

3 Energy Efficiency Ratio Requirements

With the intensification of the global energy crisis and the increasing awareness of environmental protection, the energy efficiency ratio of chillers has become one of the important indicators to measure their performance. Efficient and energy-saving chillers can not only reduce the operating costs of enterprises, but also reduce energy consumption and carbon emissions, meeting the requirements of sustainable development. Therefore, when choosing a chiller, priority should be given to products with high energy efficiency ratios, and attention should be paid to the application of their energy-saving technologies.

4 Requirements for maintenance convenience

1）Modular design

Modular design makes the various components of the chiller relatively independent, making it easy to disassemble and replace. When a component malfunctions, it can be repaired or replaced without stopping the machine, greatly reducing maintenance time and minimizing the impact on production.

2）Remote monitoring and fault diagnosis

Modern chillers are commonly equipped with remote monitoring systems and fault diagnosis functions. Through the remote monitoring platform, users can real-time understand the operating status and performance parameters of the chiller; When the equipment malfunctions, the system can automatically diagnose the fault and provide solution suggestions, improving the efficiency and accuracy of maintenance.

5 Security requirements

1）Electrical safety

As an electrical equipment, the electrical safety of a chiller is crucial. The equipment should comply with relevant national electrical safety standards and have safety functions such as overload protection, short circuit protection, and leakage protection; At the same time, the operation interface should be designed reasonably to avoid safety accidents caused by misoperation.

2）Refrigeration system safety

The refrigeration system is the core part of the chiller, and its safety directly affects the stable operation of the entire equipment. The refrigeration system should be equipped with safety devices such as high pressure protection, low pressure protection, and compressor overheating protection; At the same time, the selection and use of refrigerants should also comply with environmental and safety requirements.

6 Intelligent management requirements

With the continuous development of technologies such as the Internet of Things and big data, intelligent management has become a new trend in the development of chillers. Intelligent chillers can automatically collect and analyze operational data, achieving self optimization and fault warning of the equipment; At the same time, by interconnecting with other production equipment, intelligent control and optimized scheduling of the production process can be achieved, improving production efficiency and product quality.

In summary, the chillers used in drying equipment have strict requirements in terms of technical performance, environmental adaptability, energy efficiency ratio, maintenance convenience, safety, and intelligent management. Only chillers that meet these requirements can provide stable and reliable cooling support for drying equipment, ensuring smooth production processes and steady improvement in product quality.
