The HACST ZHX features a combined flow configuration, blending parallel airflow over the coil with crossflow through fill media for enhanced thermal performance. Ideal for refrigeration and HVAC systems demanding maximum condensing efficiency and extended approach under humid conditions.
Working Principle
Refrigerant condenses inside the coil as water and air flow downward in parallel over it. Following the coil, spray water and air pass through PVC fill horizontally, promoting additional evaporation and heat rejection before discharge.
Key Benefits
- Superior condensing performance via dual-stage heat rejection.
- Reduced scaling on coil—evaporation shifts to fill region, keeping coil surface cleaner.:contentReference[oaicite:1]{index=1}
- Colder spray water by 3–5°C, further reducing scale tendency.:contentReference[oaicite:2]{index=2}
- Fast approach achievable—great for tight condensing loads.
Typical Technical Range
| Parameter | Typical Range |
|---|---|
| Capacity | 120–2,500 RT |
| Fan | Axial, low-noise |
| Fill | High-efficiency PVC/PP |
Engineering Options
- High-durability fill for salty air or algae-prone water
- VFD fans, drift eliminators, recirculation basin modeling
- Winterization valves or basin heating systems
Selection Guide
- Ideal where you need condensing within a few degrees of wet-bulb.
- Not ideal for dusty or cold climates due to fill fouling or icing.
O&M
- Monthly: Clean fill, inspect spray nozzles.
- Quarterly: Test drift loss, flush basin.
FAQ
Q: Why use combined flow vs counterflow?
A: Combined flow gives higher total cooling via added fill—great for high load and high humidity areas.
