Advantages of DC variable frequency chiller
1. Efficient and energy-saving
a. The high-precision chiller adopts a DC variable frequency compressor, DC variable frequency controller, and electronic expansion valve throttling, which makes its energy efficiency ratio more than 25% higher than that of the rated unit.
b. By adjusting the frequency of the compressor to change the cooling capacity and match it with the thermal load, there is no need for the inevitable "big horse pulling small car" phenomenon of the rated machine, saving energy by 20% -60%
2. High temperature control accuracy
The DC variable frequency chiller can accurately control the outlet water temperature accuracy within ± 0.1 ℃ - ± 0.2 ℃ by adjusting the working frequency of the compressor at 1Hz per stage, combined with the control of the electronic expansion valve, which perfectly meets the requirements of various high-end equipment for cooling water temperature accuracy.
3. High reliability and long lifespan
Due to the lack of frequent start-up and shutdown, the high current during start-up and shutdown (3-4 times that of normal operation) is avoided, and most of the time it works in a low-frequency state, greatly extending the life of the compressor and equipment. (According to national data, the non start stop working mode can extend the life of the compressor by more than 3 times compared to the start stop working mode), greatly reducing the failure rate of the product.
4. Low noise, less heat dissipation during indoor work
Variable frequency chillers generally have a soft start when the compressor does not stop during operation, thus avoiding the noise caused by frequent start-up and shutdown of the rated machine. Due to its low overall power consumption, the machine emits less heat indoors, reducing the cooling load of indoor air conditioning.
5. One drag multi function
A variable frequency chiller can provide shared cooling for multiple devices with different heat loads (multiple devices working simultaneously or with the same water temperature requirements), without the need to match multiple chillers with different cooling capacities for devices with different heat generation.
