Classification by Core Compressor Type
Piston (Reciprocating) Refrigeration Units
Characteristics: Simple structure, low cost; single-unit capacity is generally below 580 kW.
Applications: Small cold storage facilities, convenience stores, small workshops, and other small-to-medium, low-load scenarios.
Screw Refrigeration Units
Characteristics:Stable operation, stepless cooling capacity adjustment; single-unit capacity falls between piston and centrifugal types.
Applications: Large and medium-sized air conditioning systems, commercial cold chain warehouses (1,000–20,000 m³), and blast-freezing facilities.
Centrifugal Refrigeration Units
Characteristics: High single-unit cooling capacity (exceeding 1,160 kW), stable operation, low noise; performance tends to drop at partial loads.
Applications: Central air conditioning systems for massive structures such as large commercial buildings, hospitals, and stadiums.
Scroll Refrigeration Units
Characteristics: Compact structure, low noise, relatively low cooling capacity, high operational reliability.
Applications: Residential air conditioners, small freezers, and temperature control equipment for small-to-medium commercial spaces.
Magnetic Levitation Refrigeration Units
Characteristics: No mechanical friction, energy savings of up to 35%, no need for lubricating oil maintenance.
Applications: Scenarios requiring high energy efficiency and low noise, such as data centers, rail transit systems, and hospital operating rooms.
