Xindacool original refrigeration equipment, air cooler, condenser, evaporator, grid compatible voltage, adaptability to voltage fluctuation, and selection of key points. The first part (42 characters): The power grid parameters vary greatly among countries. xindacool provides a multi-battery version for your equipment, which is suitable for industrial environments with large voltage fluctuations. The standard voltage range covers 220 V single-phase, 380 V three-phase and 415 V three-phase. The supported frequency is 50 Hz/60 Hz, and the allowable voltage variation range is 10%. The equipment can run stably and continuously. In some developing areas abroad, the fluctuation of power grid can reach 15%; Therefore, the voltage protection module must be installed. If the deviation exceeds the critical value of 12%, the equipment will automatically stop to avoid the danger of compressor combustion. The 50 Hz model can be directly used in the 60 Hz network, but the speed can be increased to 20%, thus increasing the compressor load. Direct use at different frequencies is not allowed. It should be configured according to the manufacturer's corresponding frequency. The starting current of the unit is 3-6 times of the rated current. The high-power device includes a soft starter, which can limit the starting current to 1.8 to 2.2 times the rated value, thus reducing the impact on the field transformer. When multiple cooling devices are turned on at the same time, accumulated surge current will be generated. The control system adopts hierarchical starting logic, and the starting interval is 8 to 12 seconds, which can reduce the capacity requirement of transformer by 28%. The EC fan motor is designed with a wide voltage range, which can run even under the fluctuation of -15% to +10%, but the compressor can't bear the voltage beyond the allowable range, because 71% of network failures are caused by compressor damage. Under T3 condition, the temperature is 55°C, the voltage is low, and the risk of overvoltage protection increases. Xindacool shall conduct a complete load test before leaving the factory to simulate the voltage and frequency fluctuation conditions for at least 1.5 hours to confirm the effectiveness of the protection logic. It is exported to markets such as Saudi Arabia and parts of Africa, where the network has a high level of harmonics. Harmonic suppression module can be selected to reduce the interference to the control panel and reduce unnecessary alarm failures. Voltage and frequency customization belong to ODM range. The evaluation period of the North American version of 480 V 60 Hz is 3 to 5 working days, and the delivery time is 5 to 7 days longer than the standard model. The third-party test report clearly shows the voltage and frequency conditions. Cooling capacity and power vary with voltage, and the maximum change rate is 7%. The technical drawings and electrical drawings shall completely match the required voltage version. It is not allowed to mix the circuit boards with different voltages, because the wrong connection will directly damage the electrical components. The equipment identification board shall print out the voltage and frequency parameters, which meet the requirements of UL, CE and SASO labels, and ensure that the parameters of the identification board match the physical configuration perfectly. After-sales technical service: The damage caused by network failure is not included in the standard warranty. In areas with bad voltage conditions, it is recommended to evaluate and select additional protection modules in advance to reduce the subsequent maintenance costs. FAQ 1。 Can 50 Hz equipment work under the wiring connection changed to 60 Hz? No, the increase of speed will cause the compressor to overload and quickly damage the equipment. 2. If the voltage changes by 15%, can it be used without a protection module? It is not recommended, because it will nearly double the possibility of compressor failure. 3. Are the hardware or software functions started by time offset? In the standard model, the logic is realized by software, and there is no need to purchase additional hardware costs. 4. Is it necessary to use Xindacool as a supplement to voltage stabilization equipment? You can choose to include it, or customers can buy it directly at the project site. 5. What is the influence of high harmonics on refrigeration system? Code that may cause errors is in co.
