    Variable Frequency Control Technology of Refrigeration System

    In the frequency conversion refrigeration system, even if the power frequency 50HZ is fixed, can change the
    frequency through the frequency changer, thus adjusts the compression rotational speed, causes the cold quantity
    continuously to change, guarantees the compressor movement load in the test box the actual load to match (namely
    test body temperature Increase, the compressor frequency to rise, improve the cooling capacity, on the contrary, the
    compressor frequency to reduce and reduce the cooling capacity) greatly saves the unnecessary loss of operation to achieve energy-saving purposes. In the beginning of the test chamber can also run by increasing the frequency of the compressor to improve the capacity of the cooling system to achieve the purpose of rapid cooling.
    The chamber adopts frequency conversion refrigeration system, which can precisely control the temperature of the box body, make the temperature of the box body constant, the temperature fluctuation is small, and the suction and discharge pressure of the refrigeration system is stable and the compressor runs stably and reliably. Electronic expansion flow servo.
    Refrigeration system technology Other energy - saving technologies
    A) The use of PID + PWM principle VRF technology (electronic expansion valve according to the thermal conditions of flow control)
    Low-temperature working state, the heater does not participate in the work, through the PID + PWM regulation of the cooling (cooling capacity of the air flow control system); low-temperature working conditions, the use of the principle of PID PID VRF technology (refrigerant flow control) Flow rate and flow direction of the cooling pipe, cold side of the pipeline, heat the next three-way flow pipe to adjust to achieve the work of the temperature is automatically constant, this method in low temperature conditions, the studio can automatically achieve a constant temperature, Low temperature conditions, can achieve a 30% reduction in energy consumption. The technology is based on Danfoss ETS system electronic expansion valve, can be applied to different cooling capacity requirements of the cooling adjustment, both at different cooling rate requirements, to achieve the compressor cooling capacity adjustment.
    B) the size of two sets of compressor design technology, according to load conditions automatically start and stop (large series is designed)
    The refrigeration unit is equipped with a set of semi-hermetic compressors composed of binary cascade refrigeration system plus a full-density single-stage refrigeration system. Configure the mother; according to the load conditions inside the box and the cooling rate of intelligence to open the different compressor groups, so that the cooling capacity of the box and the compressor output power to achieve the best match, in order to achieve the best operating conditions in the compressor section circle to Extend the service life of the compressor. More importantly, a large set of traditional design compared to the energy-saving effect is very obvious, you can achieve more than 30% of the temperature control. With VRF technology)
