1. Definition of primary system and secondary system
Chilled water system is a refrigeration system that uses cooling water to provide cooling capacity for buildings, equipment and processes. It mainly consists of two parts: a primary system and a secondary system.
The primary system is responsible for generating and delivering cold water.
The secondary system is responsible for outputting cold water to the end-use equipment for cooling.
2. Structure of primary system and secondary system
The primary system mainly consists of a refrigeration system, cooling tower, pump, water tank and pipeline. Its function is to generate and transport cold water.
The secondary system is mainly composed of end-use equipment, water pumps and pipelines. Its function is to transport cold water to the end-use equipment for cooling.
3. The role of primary system and secondary system
The primary system and secondary system of the chilled water system each play different roles. The primary system is mainly responsible for processing water into the form of cold water, and then transporting the cold water to the secondary system to meet the needs of end-use equipment.
The secondary system is responsible for delivering cold water to the end-use equipment for cooling.
4. Scope of application of primary system and secondary system
The scope of application of primary system and secondary system is different. Primary systems are suitable for air conditioning systems in buildings, factories and equipment.
The secondary system is suitable for equipment and processes that require cooling, such as heat treatment equipment, injection molding machines, laser cutting machines, medicine, food and other industries.
5. Advantages and disadvantages of primary system and secondary system
The primary system reduces the pipes, pumps and other equipment of the terminal building, but will affect the indoor air quality and the treatment of equipment condensate water.
The secondary system can improve refrigeration efficiency, save energy, and reduce noise, but it requires pipeline cleaning and disinfection, and the maintenance cost is high.
To sum up, the primary chilled water system and the secondary system each have their own advantages and disadvantages, and their scope of application and functions are also different. Air conditioning systems in buildings, factories and equipment are suitable for primary systems, while equipment and processes requiring cooling are suitable for secondary systems. During use, you need to select according to actual needs to achieve the best cooling effect.
