EVI + DC Inverter, Stronger Cooling Performance
Meet the storage temperature requirements of -25°C~+20°C;
Start up the EVI, the unit still can get good performance at an Evaporating Temperature of -30℃ and a Condensing Temperature of 55℃。
Energy saving
The DC Inverter condensing unit changes the cooling capacity by adjusting the compressor speed (20~110HZ) to adapt to the load changes in cold storage. This adjustment method can improve the unit efficiency and energy saving in the partial load. Overall it can save energy 35% more than the fixed frequency unit.
Precise temperature control
The DC Inverter condensing unit can accurately adjust the cooling capacity according to the temperature requirements in cold storage, making the temperature in storage more stable. This precise temperature control can ensure the freshness of food and other items and extend their shelf life.
Fixed speed ±5℃ vs variable frequency ±2℃
Low Noise
The DC Inverter condensing unit adopts advanced compressor technology and shock-absorbing measures, resulting in low noise during operation. This reduces interference with the surrounding environment and improves comfort.
Smooth Start-Up
- Fixed speed unit, compressor capacitor start, large instantaneous current at start, large noise and vibration
- The DC Inverter unit starts from a standstill, and the compressor gradually increases the operating frequency, resulting in a smoother start, less energy consumption, and less noise and vibration.
Hot Fluorine Defrost
- Automatically enter and exit the defrost mode, defrosting completely and reliably.
- Defrosting time is shortened by 70% (only 3-5 minutes each time)
- Defrost power consumption reduced by 80%
- No need for electric heating, high efficiency, and low consumption.
- Can meet the complete defrosting requirements of high frost fan in high humidity environment
- Automatically record the operation data of the unit before exiting the defrost mode, ensuring the unit returns to the proper refrigeration quickly.
- During the defrost mode, the temperature rise in the cold storage is small (12-15℃ for ordinary units and 3-5℃ for DC Inverter units)
- For example, each defrost for a 3HP unit saves energy of 1 kW‧h, then it can save energy about 4-5 kW‧h per day, and 1,500 kW‧h per year at least.
High Reliability
- The DC Inverter condensing unit adopts core components of world-famous brands
- Panasonic inverter compressor
- Danfoss valves
- EBM fan
High-quality compressors and components, undergoing strict production processes and quality control, have high reliability and stability. This can ensure the stability and durability of the unit in long-term operation
