Holtop Dynamo Vortex Modular Air-Cooled Chilled Water (Heat Pump) Unit
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.
Product Features
Module 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 accurate frost determination with 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 for independent transport and installation without special equipment or dedicated machine room. Supports both fixed and variable water flow systems.
Safe Operation Control: Comprehensive 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.
