Air-Cooled Flooded Screw Chiller (Heat Pump)
Description
Energy-efficient solution, comfort and quiet, smart defrosting, cloud-based data management system.
Features
- Energy-Efficient Solution
Eco-friendly R134a, various efficiency options to meet different requirements.
Economizer is added to substantially improve cooling/heating performance. Heating COP under low temperature is improved by 15%-20%.
-Comfort and Quiet
Precise water temperature control (±0.3°C), energy provision by demand.
Low-noise axial flow fan and long type air duct diversion to effectively reduce the airflow noise.
- Reliability
Multiple safety protection technologies can ensure safe operation.
Unique smart defrosting technology guarantees efficient defrosting.
-Intelligent Control
Smart control system and cloud-based data management system for automatic control of the unit.
Technical Specification
-Patented High-Efficiency Compressor from Germany
Three-stage oil separator with efficiency up to 99.5%.
With the slide valve for stepless regulation, a single compressor can precisely match 25% – 100% load changes.
The screw rotator reaches micron-level precision.
Efficient motor with large capacity can significantly increase the EER.
-High-Efficiency Heat Exchanger
Efficient flooded-type shell-and-tube heat exchanger, super-efficient heat exchange tube, inner-threaded tube, and external fins substantially increase the heat exchange efficiency.
V-type heat exchanger is adopted at the air side, with dual-module seamless configuration.
New open-window aluminium fin greatly enhances the air turbulence and increases the heat exchanging efficiency by about 8%.
-Unit Microcomputer Control Center
Advanced pre-control function enables measures to be taken promptly before actual failure occurs to avoid frequent startup/shutdown.
Full-lifecycle cloud-based data management system provides comprehensive control and powerful big data support for customers.
-Unique Smart Defrosting Technology
Smart defrosting: Based on temperature parameters measured by the sensor, the unit can precisely determine the existence of frost by analyzing the unit operating parameters.
Minimum defrosting duration: Under national defrosting conditions, the defrosting duration is only 4.5% of the total heating duration.
Defrosting EXV control: The EXV can precisely control the opening during defrosting to avoid problems of traditional thermal expansion valve such as liquid hammer and oil shortage.
