Ⅰ、Product Name: Parallel Condensing Unit

Ⅱ、Product Features:

1. High reliability (redundant backup)

Uninterrupted operation during failures: When one compressor fails or requires maintenance, the remaining units automatically take over, ensuring the system remains operational.

N+1 redundancy: Commonly configured as "3+1" or "2+1", ensuring more reliable continuous operation in critical scenarios.

Evened Service Life: The controller automatically rotates the start-stop cycles, ensuring equal operating time for each compressor and extending the overall service life of the unit.

Comprehensive protection: A full set of safety protections including phase loss, high/low voltage, oil pressure, and overload protection.

2. High efficiency and energy-saving

Multi-level energy regulation

High efficiency under partial load: Actual operation typically occurs at 30%–70% load, with the COP of parallel units approaching full load; the efficiency of individual units drops by over 50% under low load conditions.

Comprehensive energy savings of 30%–60%: Significantly more energy-efficient than single-unit systems with equivalent cooling capacity.

Multiple evaporation temperatures: Supports 2–3 different evaporation temperatures, suitable for simultaneous cooling of cold storage units, refrigerators, and ice makers.

3. Flexible capacity with strong adaptability

Combinatorial flexibility: 2–8 compressors of the same model/size can be paired, offering extensive cooling capacity (e.g., 10–500 kW).

Modular scalability: Additional capacity can be directly added through parallel unit integration without requiring replacement with larger units.

4. Compact structure with high integration

Shared components: multiple machines share oil separation units, liquid storage tanks, main control systems, and racks, reducing redundant equipment.

Space efficiency: Overall integration saves over 30% in data center area compared to multiple standalone systems.

Low noise and vibration: The scroll parallel configuration delivers 8–10 dB lower noise and reduced vibration compared to piston chillers with equivalent cooling capacity.

5. Easy maintenance and management

Online maintenance: A single compressor can be shut down for inspection without disrupting system operation.

Centralized control: Microcomputer/PLC-based automatic group control with comprehensive features including remote monitoring, fault alarms, and complete data recording.

Reliable oil return: High-efficiency oil separation + electronic oil balance, eliminating the need for daily refueling
