The National Development and Reform Commission's "Green and Efficient Refrigeration Action Plan" clearly states: By 2030, the refrigeration energy efficiency of large public buildings will increase by 30%, and the market share of green and efficient refrigeration products will exceed 40%. According to statistics, air conditioning systems account for 50% of the total power consumption of public buildings, and the energy consumption of computer room systems accounts for 85% of air conditioning systems. Therefore, improving the energy efficiency of computer rooms is a key breakthrough in achieving energy conservation.
The energy efficiency ratio (EER) of traditional refrigeration computer rooms in China is generally 3.0, while high-efficiency computer rooms need to reach 5.0 or above, with huge energy-saving potential. Its value lies not only in equipment upgrades, but also in optimizing water system control. Among them, valves, as the core components of fluid control, connect the entire chain of "heat dissipation demand-flow control-energy efficiency management" in series, which is the key to achieving precise cooling.
1. Energy-saving technology path of valves
1. Precise flow control: cooling on demand
Dynamic response to load changes: real-time monitoring of equipment heat load through sensors, automatic adjustment of valve opening, and priority cooling of high-heat areas.
Balanced pipe network resistance: In complex water systems, valves eliminate the problem of "near-end overcooling and far-end overheating" by compensating for local pressure drops, ensuring balanced flow distribution.
2. System safety guarantee
Emergency cut-off and anti-leakage: When a pipeline rupture or temperature abnormality is detected, the solenoid valve can be closed in milliseconds to isolate the fault area and prevent accidents caused by coolant leakage.
3. Energy efficiency optimization core
Low-load energy-saving operation: During low-load periods, the valve cooperates with the variable-frequency water pump to reduce the flow and reduce system energy consumption.
Waste heat recovery coordination: Switch the flow direction through the three-way reversing valve to introduce the waste heat of IT equipment into the building heating system.
2. Core performance requirements of efficient machine room valves
Reliability: support 7×24 hours operation, mechanical structure withstands more than 100,000 opening and closing operations
Flow resistance control: adopt straight-through flow channel (ball valve/butterfly valve) to reduce pressure loss and reduce pump power consumption
Sealing: two-way pressure-bearing sealing design, fast cut-off capability in seconds
Intelligent control: support electric/pneumatic actuators, integrated with BMS (building management system) and DCIM (data center management system)
