Even-pressure Variable-flow Smart Tower for High-efficiency Plants
Patented constant-pressure water supply + variable-flow even water distribution, 20%-120% variable flow
Applications: the full cooling tower range including PL, LC, HMK, LMB, and integrated units
Even-pressure Variable-flow Water Supply Technology
Prefabricated constant-pressure water troughs and variable-flow nozzles maintain even water distribution across a 20%-120% flow range, delivering significant energy savings at partial load.
Technical Principle & Verification
Inlet water is changed from conventional external piping to axisymmetric in-tower inlet — prefabricated constant-pressure water troughs plus a low-resistance, anti-siphon hydraulic-balancing internal inlet system, with multi-level variable-flow nozzles of different types arranged in the distribution basin to keep even water distribution at partial load. At the Guangzhou Tianhe Park high-efficiency plant project (PL-32463C×4), the measured cumulative average COP of the plant reached 5.84.
Applications: PL Series cooling towers for high-efficiency plants and the cross-flow open circuit series
Permanent Magnet Direct Drive Technology
High-torque permanent magnet synchronous direct drive motors replace conventional "motor + gearbox/belt" transmission — maintenance-free and highly efficient.
Technical Principle & Verification
The permanent magnet synchronous motor drives the fan directly, eliminating mechanical losses in intermediate transmission. Combined with variable-frequency control, it automatically adjusts fan speed based on real-time thermal load, with particularly notable savings at partial load. The cooling towers at Shenzhen Metro Nanshan Book City Station use permanent magnet motors, helping this high-efficiency air-conditioning plant demonstration station enter the COP 5.0 era; all cross-flow towers of Shenzhen Metro Phase IV are equipped with permanent magnet synchronous motors.
Applications: PL Series (optional), PL-C-ZN Smart Cooling Tower, Digital Twin Smart Cooling Tower
Water-saving & Plume Abatement (Anti-Plume) Technology
Combined dry-wet operation switches between wet mode in summer and dry mode in winter, significantly reducing water consumption and eliminating visible plume, with a winter water-saving rate above 85%.
Technical Principle & Verification
LANXUN participated in drafting the association standard "Plume Abatement and Water-saving Mechanical Draft Cooling Towers" (T/CGMA 1001-2021). Plume abatement index >100% (design point: dry-bulb 5°C, RH 85%); the HRN condensing module achieves a 16% annual water-saving rate (a 1000m³/h tower saves about 19,200m³ per year); the gas-liquid wall heat exchange coefficient is 30 times higher than gas-gas heat exchange.
| Technical Route | Principle | Representative Product |
|---|---|---|
| Dual-Path Anti-Plume | Dry/wet air channels mix exhaust to avoid the saturation curve, producing no visible plume | HMK Dual-Path Series |
| Open/Closed Switching | Dual open + closed systems in summer, closed-circuit only in winter | PL Water-saving & Plume Abatement |
| Combined Dry-Wet Operation | Spray stops in winter, heat dissipation via fin structure only | LXWD, LMB-RB Series |
Applications: HMK Dual-Path Anti-Plume, PL open/closed water-saving & plume abatement, LXWD dry-wet combined, LMB-RB counter-flow dry-wet, LMB-F&SF combined-flow, HRN industrial plume abatement tower
Isenthalpic Adiabatic Cooling Technology
Water evaporation absorbs heat to lower the air dry-bulb temperature at constant enthalpy — an efficient cooling method operating without compressors and with zero water consumption.
Technical Principle & Verification
As air passes through the adiabatic pad (wet curtain), water evaporation absorbs the air's sensible heat, lowering the dry-bulb temperature at constant total enthalpy and further reducing the cooling tower inlet water temperature. Optional wet-film or atomizing devices provide adiabatic cooling, with no refrigerant and a wide operating range from -30°C to 50°C. As a pre-cooling module for conventional data center air conditioning, it helps achieve PUE <1.25. Certified by EU CE and US CTI, it is a high-tech product.
Applications: LAD Series isenthalpic adiabatic cooling units
