Variable-Frequency Multi-Split Cold Storage, One Outdoor Unit Serving Multiple Temperature Zones
0 to 5°C, Minus 5 to Minus 10 and Minus 18 Under One System: Stepless Modulation, Smaller Machine Rooms and Sensors That Report Before a Fault Does
A conventional one-unit-per-room layout multiplies outdoor units and raises upfront investment, while fixed-speed equipment cycles constantly, swings room temperature and drives product loss. A variable-frequency multi-split system places one outdoor host against indoor evaporator terminals, reads the load of every zone and adjusts compressor frequency and refrigerant flow. Holding at 0 to 5 degrees, chilling at minus 5 to minus 10 and freezing at minus 18 coexist, with capacity modulating steplessly, a smaller machine room, simple piping and sensors for remote monitoring. The scheme suits small and mid-sized multi-zone projects, while large blast freezers still favor dedicated screw or piston units. EXTRCOOL provides variable-frequency cold storage solutions.
