VCR Series In-row Refrigerant Pump Precision Air Conditioner

* High efficiency and energy saving:
* DC variable-frequency compressor with dynamic cooling capacity adjustment from 20% to 100%, delivering cooling on demand.
* High-efficiency, fully enclosed centrifugal refrigerant pump with power consumption ≤550 W, ensuring superior energy savings.
* Refrigerant pump module can be directly integrated into the V-type outdoor unit, reducing on-site space requirements and piping.
* High-efficiency, low-noise backward-curved EC centrifugal fan with speed adjustment based on real-time heat load to maximize energy savings.
* Electronic expansion valve with faster response and more precise flow regulation, working in coordination with the variable-frequency compressor for enhanced energy efficiency.
* Variable-frequency outdoor fan that adjusts smoothly and rapidly based on system pressure changes, ensuring high-efficiency operation.
* High-efficiency evaporator featuring internally grooved copper tubes and hydrophilic-coated, louvered aluminum fins for superior heat exchange efficiency.

2. Safe and reliable：
* Uses certified high-quality components for enhanced reliability from the ground up.
* DC variable-frequency technology with low starting current to reduce impact on the power grid.
* At low loads, it precisely controls supply and return air temperature and humidity.
* Intelligent monitoring of power supply voltage, frequency, and three-phase imbalance.
* Standard oil separator to prevent compressor damage due to oil shortage.
* Standard check valve to prevent damage due to refrigerant migration into the compressor during shutdown.
* Standard sight glass for intuitive and effective inspection of refrigerant status in system piping.
* Rigorous, repeated testing to meet high standards and ensure high-quality delivery.
* Two-stage evaporator with a drip tray in the middle to effectively prevent water carryover.
* High-efficiency, environmentally friendly R410A refrigerant in compliance with international green refrigerant standards.
* High return-air temperature design to further improve cooling efficiency.

3. Intelligent control:
* An advanced control system for intelligent management of the compressor, expansion valve, fan, and other components, adjusting cooling capacity and airflow on demand.
* 7-inch premium true-color capacitive touchscreen, offering multiple display options such as graphical status and temperature/humidity curves.
* High-speed, flexible CAN communication protocol supporting group control of at least 64 units.
* External connection for at least 10 temperature sensors to accurately detect temperature field variations.
* Standard RS485 interface with optional SNMP interface.
* Multi-level password protection with hierarchical access control.

4. Flexible configuration:
* High cooling density with full coverage from 25kW to 60kW.
* Supports on-site modification and future expansion with refrigerant pumps, etc.
* Supports pressure boosting mode to meet site requirements for ultra-high elevation difference.
* Standard evaporative humidifier; optional electrode humidifier.
* Optional centralized outdoor unit with V-shaped heat exchanger for a smaller footprint and larger heat exchange capacity.
* Optional top piping/drain to meet different site requirements.
* Optional supply air grille to provide left and right air discharge.
* Optional dual power supply.
