Recent research on chillers (cooling water units) has focused on the following areas:
1. **Cryogenic Refrigeration Technology**
- Japanese researchers have conducted systematic research on ultra-low temperature refrigerators (Stirling, pulse tube, GM), focusing on efficiency and reliability improvements in third-generation pulse tube refrigerators.
2. **Novel Refrigerants and Circulation Systems**
- Transcritical CO₂ (R744) systems have achieved wide temperature range operation from -50℃ to 90℃; solid-state refrigeration (electrocalorimetric effect, magnetocaloric effect) prototypes have achieved a COP of 12.7; AI energy efficiency optimization algorithms can improve annual power savings for data center chiller units by approximately 15%.
3. **Application of Liquid Cooling Technology in High-Power Scenarios**
- With the increasing power consumption of AI chips, liquid cooling has become a key technology for reducing PUE and improving heat dissipation efficiency; key components such as liquid cooling systems, cold plates, and UQDs are entering a rapid commercialization phase both domestically and internationally.
4. **Industry Market and Investment Prospects**
- The 2024-2025 industry report shows that the liquid cooling market is transitioning from initial breakthrough to large-scale penetration, leading to improved profit expectations for related companies. We recommend focusing on companies such as Foxconn Industrial Internet, BYD Electronic, and Siquan New Materials.
5. **Safety and Performance of Chillers in the Medical and Building Fields**
- Research indicates that hospital chilled water systems pose a risk of microbial contamination. We recommend switching to chilled water distributors or optimizing filtration designs to reduce biofilm growth.
- In building energy conservation projects, the combination of chiller units and cooling towers remains a core component of large-scale central air conditioning systems, with capacities ranging from 175kW to 3500kW.
6. **Operating Status of China's Chiller Industry (2014-2019)**
- Bosdata's industry report provides macroeconomic data such as the domestic chiller market size, supply and demand forecasts, and price indices, providing a basis for companies to formulate medium- and long-term investment strategies.
**Overall Trends**:
- **High Efficiency and Low Carbon**: Utilizing new refrigerants (CO₂) and solid-state cooling technology, coupled with AI-optimized control, lower energy consumption is achieved.
- **Liquid Cooling Penetration**: Liquid cooling is rapidly replacing traditional air cooling in high-power scenarios such as data centers and AI computing platforms.
- **Safety and Hygiene**: Medical systems are demanding improvements in the microbial risk of chillers.
- **Market Expansion**: Domestic and international companies are increasing R&D investment, and the industry size is expected to maintain double-digit growth in the coming years.
