Applicable industries:

Air supply mode: horizontal air supply, which is conducive to the uniformity of the wind distribution around each product when placing multiple products. Wind direction adjustment: The air outlet is installed with double-layered louvers, which can adjust the wind direction up and down, left and right. Wind speed / wind volume adjustment: configuration of Dexi inverter, according to the different test requirements of customers to adjust the operation frequency of the circulating motor, so as to achieve the purpose of adjusting the wind speed / wind volume in the box. Wind field simulation: SOLIDWORKS three-dimensional mapping and modeling, and the model built ANSYS analysis software to analyze the wind field and temperature distribution and other parameters.

Refrigeration system frequency control technology: In the frequency conversion refrigeration system, even if the power supply frequency 50HZ is fixed, the frequency can be changed through the frequency converter, so as to adjust the compressor speed, so that the cooling capacity is continuously changed to ensure that the compressor operating load matches the actual load in the test chamber (i.e., the temperature inside the test chamber rises, the compressor frequency rises, increasing the cooling capacity, and vice versa, the compressor frequency decreases, reducing the cooling capacity), which greatly saves the operating unnecessary loss, to achieve the purpose of energy saving. In the test chamber at the beginning of the operation of the compressor can also be improved by increasing the operating frequency of the compressor, improve the capacity of the refrigeration system to achieve the purpose of rapid cooling test chamber using frequency conversion refrigeration system, can accurately control the temperature inside the box, so that the temperature inside the box constant temperature fluctuations, but also to ensure that the refrigeration system suction and discharge pressure is stable, the compressor is more stable and reliable operation.

The inverter controller system mainly adjusts the compressor capacity according to the actual load size to ensure that the total output capacity of the compressor matches the actual load. The control principle is as follows. According to the temperature and suction superheat to be achieved by the box to determine the compressor suction temperature, query the suction pressure value corresponding to the temperature of the refrigerant, set the corresponding suction pressure change range value through the operation panel, after setting, the controller will give a signal (from the suction pressure sensor) according to the change of suction pressure, automatically control the input frequency of the compressor, so as to change the rotational speed and realize Automatic stepless adjustment of the cooling capacity, to ensure that the refrigeration unit operating capacity with the actual load required by the box, to achieve no waste, to minimize the cost of running the refrigeration unit. The role of the electronic expansion valve control system is mainly through the adjustment of the electronic expansion valve opening degree to control the evaporator superheat, to ensure that the actual load in the box and the system to provide a balance of cold, can accurately control the temperature in the box, and make full use of the evaporator.
