Regarding the selection of refrigeration equipment, if it is necessary to cool deionized water to 2℃and maintain stability, the following key points should be noted:

A closed cycle chiller made of corrosion-resistant materials such as titanium alloy and 316L stainless steel should be selected to avoid metal corrosion caused by the low conductivity of deionized water.

The equipment should be equipped with a precise temperature control system (with an accuracy of ± 0.1 ℃) and a built-in water quality monitoring module (such as a conductivity sensor) to monitor the purity of water in real time.

Industry adaptation:

In the pharmaceutical field, a hygienic design that complies with GMP standards and is equipped with online sterilization functions (such as ozone or ultraviolet radiation) is required.
Precision instrument cooling: Add variable frequency pumps and buffer tanks to achieve fluctuation control of ± 0.05 ℃.
Industrial application: Modular design, expandable to -10 ℃ working conditions, flow range covering 5-500L/min.

In terms of heating methods, common ones include steam heating, thermal oil heating, etc. Steam heating may require boilers, suitable for factories with steam supply; Thermal oil is suitable for high temperatures and requires uniform heating. Cooling methods may include water cooling, air cooling, refrigeration units, etc. High water cooling efficiency, but requires a stable water source; Air cooling is suitable for situations with low ambient temperatures; Refrigeration units can accurately control temperature, but the cost is relatively high.

At the same time, it is necessary to consider the material of the equipment, the intelligence of the control system, safety, energy efficiency, and the convenience of maintenance and cleaning.

Selection suggestion: jacketed reactor+heat exchange system; Thermal oil: High temperature uniform heating, suitable for scenarios with large capacity or requiring higher temperatures (>100 ℃). Rapid cooling: Equipped with a refrigeration unit (such as a chiller) to achieve active temperature control. Natural cooling: Suitable for scenarios with low cooling speed requirements through cooling towers or circulating water systems.

When electrical equipment is operating outdoors, it may encounter high temperature environments. For example, in direct sunlight in the summer, the temperature may be very high. If the equipment overheats, it will affect performance or even damage. At this time, the chiller can cool down and keep the equipment running stably. High-power equipment, such as transformers, inverters or generators, these equipment will generate a lot of heat during operation. If the heat cannot be dissipated in time, it may lead to performance degradation: high temperature will reduce the efficiency of electronic components (such as increased resistance and insulation aging). Shortened life: continuous high temperature accelerates equipment aging and even causes failures (such as capacitor bursting and circuit board burning). Safety hazards: overheating may ignite surrounding materials or cause equipment to short-circuit. At this time, the chiller can cool down and keep the equipment running stably. If natural heat dissipation is not enough, forced cooling is required, and chillers are the solution. If the equipment shuts down due to overheating, it may cause project interruption, affecting progress and even safety. As an active cooling system, chillers can prevent this situation and improve system reliability.

To summarize, the roles of cooling systems in outdoor projects include temperature control, improving efficiency, protecting equipment, adapting to harsh environments, energy saving and environmental protection, flexibility, and safety.
