1. Overview

An air conditioning cooling tower is a critical heat rejection component in central HVAC systems, designed to dissipate waste heat from condensers into the atmosphere via **evaporative cooling**. It ensures efficient operation of refrigeration cycles and is widely used in commercial buildings (e.g., offices, hospitals, hotels) and industrial facilities (e.g., data centers). Key design considerations include chiller capacity, ambient wet-bulb temperature, and spatial constraints.

2. Iş ýörelgesi

1. Hot Water Inlet: Hot water (typically 37°C) from the chiller condenser enters the cooling tower.
2. Water Distribution: Spray nozzles evenly distribute water over the fill media.
3. Air-Water Heat Exchange: Fans drive air to interact with water in counterflow or crossflow configurations, enabling evaporative cooling.
4. Cooled Water Return: Chilled water (≈32°C) recirculates to the condenser.

4. Esasy komponentler we dizaýn

4.1 Esasy komponentler

-Fill Media: PVC or PP modules to maximize air-water contact area.
- Fan System: Axial/centrifugal fans (e.g., 7.5 kW motor for a 100 TR tower).
- Water Distribution: Rotary nozzles or fixed spray pipes.
- Drift Eliminator: Reduces water loss (<0.001% drift rate).
- Casing: FRP (corrosion-resistant) or galvanized steel (cost-effective).

4.2 Dizaýn parametrleri
- Cooling Capacity (TR): 1 TR = 3.516 kW; tower capacity = 1.2–1.3× chiller TR (to offset heat loss).
- Wet-Bulb Temperature (WBT): Critical design baseline (e.g., 28°C).
- Approach: Temperature difference between cooled water and WBT (typically 3–5°C).

5. Saýlamak we konfigurasiýa görkezmeleri

5.1 Ölçeg formulasy
Tower Water Flow (m³/h) = \[ Chiller Capacity (TR) × 3024 × 1.3 \] ÷ 5000
Example: For a 500 TR chiller → ≈393 m³/h.

6. Energiýanyň netijeliligi we durnuklylygy

- Energy-Saving Technologies:
- Variable Frequency Drives (VFDs) reduce fan power by 20–30%.
- High-efficiency fill media (15% higher heat transfer).
- Eco-Friendly Features:
- FRP compatible with low-GWP refrigerants (e.g., R-1233zd).
- Noise control ≤65 dB(A) @ 1m (ASHRAE compliant).

7. Bejeriş we näsazlyklary düzetmek

- Routine Maintenance:
- Weekly: Check water level/pH (6.5–8.5).
- Monthly: Clean fill media and filters.
- Common Issues:
- Reduced Efficiency: Clogged fills or fan imbalance.
- Abnormal Noise: Bearing wear or loose blades.

8. Adaty programmalar

- Commercial Buildings: Malls, offices (200–1,000 TR towers).
- Data Centers: Redundant N+1 configurations.
- Healthcare Facilities: Closed-loop towers for contamination control.

9. Çykdajylara salgylanma (RMB)

| Capacity (TR) | Price Range (10,000 RMB) | Remarks |
|--------------------|------------------------------|---------------------------------------|
| 100 TR | 8–15 | FRP counterflow, standard config. |
| 500 TR | 40–70 | VFD fans + smart controls. |
| 1,000 TR | 80–150 | Modular design for parallel setups. |

10. Halkara standartlar we şahadatnamalar

- ASHRAE 90.1: Energy efficiency requirements.  

- EN 13053: Ventilation system compliance (EU).  

- LEED Certification: Credits for water/energy conservation.  

Netije

Kondisioner sowadyjy diňler HVAC ulgamynyň netijeliligi üçin möhümdir. Counterflow diňleri ýokary öndürijilikli täjirçilik binalaryna laýyk gelýär, krossflow modelleri bolsa çäkli retrofitlerde has ýokarydyr. Akylly gözegçilik ulgamlaryny ileri tutuň (IoT-mümkinçilikli) we dizaýnlary ýerli WBT we durnuklylyk maksatlary bilen deňleşdiriň.

Marka teklipleri (mysal üçin, BAC, SPX, EVAPCO) ýa-da jikme-jik tehniki deňeşdirmeler üçin taslama talaplaryňyzy kesgitläň (howa zolagy, býudjet we ş.m.).
