Holtop Vortex Module-Type Air-Cooled Chilled Water (Heat Pump) Unit HFW-1120HA1
The vortex module-type air-cooled chilled water (heat pump) unit utilizes advanced modular technology with air as the cooling and heating medium. This integrated central air conditioning equipment serves as both a cooling/heating source and combined unit, designed to work with fan coil units, cabinet-type, ceiling-mounted air handling units, and fresh air units to form semi-centralized air conditioning systems.
Key Features
- Modular Combination & Hierarchical Startup: Modular design allows flexible combination without distinguishing between main and secondary machines. Supports up to 16 units per group with hierarchical startup to reduce current impact on power grid.
- Intelligent Defrosting: Multi-variable detection for precise frost determination and optimal defrost timing. Dual-system design enables interval defrosting with manual override capability in harsh conditions.
- Flexible Application: Easy unit expansion suitable for phased investment. Compact size allows independent transportation and installation without special equipment. Compatible with both fixed water flow and variable water flow systems.
- Safe Operation Control: Multiple safety protection functions with intelligent multi-variable monitoring for efficient and stable operation.
- Fault Backup Operation: Dual-compressor design ensures continued operation if one compressor fails, maintaining system functionality.

Notes:
1. Nominal cooling capacity test conditions: water flow rate 0.172 m³/(h*kW), outlet water temperature 7°C, outdoor ambient temperature 35°C.
2. Nominal heating capacity test conditions: water flow rate 0.172 m³/(h*kW), outlet water temperature 45°C, outdoor dry/wet bulb temperature 7/6°C.
3. Total water pipe for modular unit combination requires on-site fabrication and installation.
4. Modular units can be combined from 1 to 16 units as needed. Above table shows single unit parameters.
5. Control accessories (remote controller, user manual, connection cables) must be ordered separately.
