Pump-pressure dual-compressor refrigeration system
In data centers, a dual-operation architecture featuring both compressors and refrigerant pumps is widely adopted, enabling multiple operational modes—including natural cooling via pumping, vapor-compression cycles, and hybrid dual-engine operation. These modes can be flexibly switched based on temperature differentials, fully leveraging the natural cold sources available in the environment and significantly reducing the annual PUE.
Integrated/Serial
The current mainstream solution—accounting for over 90% of dual-engine compressor systems—generally supports natural cooling + mechanical refrigeration + dual-engine mode, and can also incorporate a gravity heat pipe design.
Cascade/Parallel Type + Fluorine Pump Multi-Unit System
The excellent fluoropump multi-connection system solution, due to its high requirements for oil return, is often considered for use in oil-free systems.
Coupled/Parallel Type + Fluorine Pump Multi-Unit System
An excellent fluoropump multi-connected system solution, with even higher efficiency in utilizing natural cooling sources during the transition seasons.
Chiller + Fluoropump Multi-Split System
Fluoropump multi-split system with a variety of natural cooling modes.
a. Fluoropump multi-split system with natural cooling (requires installation of a natural-cooling condenser)
b. Add a fluoropump natural-cooling system inside the chiller unit
c. The chiller unit utilizes a cooling tower to achieve natural cooling of the chilled-water side
Pump-driven two-phase cooling system
The system is driven by a refrigerant pump, which circulates liquid refrigerant working fluid in a closed loop. As the fluid flows through the evaporator, it absorbs heat and undergoes a phase change, forming a two-phase mixture of gas and liquid or a superheated gaseous fluid with low subcooling. Subsequently, the gaseous refrigerant working fluid releases its latent heat in the condenser, recondensing into a liquid state. The liquid refrigerant then flows into a storage device before returning to the refrigerant pump, thus completing the cycle. Its key technological advantages include highly efficient heat dissipation via phase change, precise temperature control enabled by pump-driven circulation, and a compact architecture with low power consumption. This system can be widely applied in fields such as electronic equipment cooling, thermal management for energy systems, and industrial cooling.
