xindacool Refrigeration Equipment Origin Factory: Air Conditioner Condenser Evaporative Cooling Full-load Partial-load Performance IEER Project Selection Calculation First paragraph (43 words): The key to evaluating the annual energy consumption of the refrigeration unit lies in the partial-load performance. xindacool provides actual measurement data for full-load and partial-load conditions, supporting the calculation of project energy consumption. The full-load performance refers to the output capacity under the rated operating condition. The testing environment is set at a temperature of 35℃ according to the national standard T1 operating condition, and the deviation of the actual refrigeration capacity of the unit from the nameplate is controlled within ±5%. The IEER (Integrated Energy Efficiency Ratio) takes into account 4 levels of partial-load conditions, which is more in line with the actual operation of the equipment throughout the year. The IEER of xindacool evaporative cooling units can reach 4.1-4.6, reducing annual electricity consumption by 17-22%. The T3 high-temperature 55℃ operating condition belongs to the full-load limit assessment. The output reduction of the 55℃ environment cooling of the compliant T3 model is controlled within 22%, while for ordinary models, the reduction can reach more than 40%. Most industrial projects operate in the 40-70% partial-load range for 70% of the year. Only considering the full-load EER for selection will cause a 14-19% deviation in the annual energy consumption calculation of the project. The N+1 multi-unit parallel system automatically reduces the number of operating units under partial-load conditions, while maintaining a higher load rate for each unit. The comprehensive IEER of the system can be further improved by approximately 8%. The EC fan motor can be adjusted continuously according to the load. Reducing the fan speed under partial-load conditions can reduce the power consumption by up to 65%, which is a key component for improving the partial-load energy efficiency. Dirty heat exchangers will simultaneously lower the full-load and partial-load performance. With a fouling thickness of 0.2mm on the heat exchange plates, the IEER value of the entire unit decreases by approximately 11%. A regular cleaning cycle needs to be set. xindacool can provide interpolation tables for performance under different ambient temperatures, covering the temperature range of 25-55℃, facilitating the design institute to conduct annual energy consumption simulation and calculation. The third-party performance tests also include full-load and 4 levels of partial-load tests. The test conditions follow the AHRI standard, and the test report can be directly used for overseas project energy consumption verification. The startup current is frequently reflected in the partial-load start-up and shutdown conditions. Configuring a soft start can reduce the impact on the power grid by 60% after multiple startups and shutdowns. It is suitable for process scenarios with large load fluctuations. The temperature control accuracy is within ±0.8℃. Reducing frequent startups under partial-load conditions can save 3-5 kWh of electricity loss per day for each unit when the frequency of invalid startups is reduced by one time. Low GWP refrigerants will change the partial-load parameters. Compared with R410A, the partial-load IEER fluctuation of R454B is controlled within ±4%. The corresponding refrigerant performance parameters must be used when selecting. The technical documents provide performance curve charts, including the changes of refrigeration capacity, power, and IEER with ambient temperature. The file format is PDF, which is convenient for engineers to import into project calculation software. Customized explosion-proof and anti-corrosion models will have their full-load and partial-load performance re-evaluated. The performance deviation is controlled within ±5%. The customization review needs to be completed simultaneously with the thermal simulation verification. FAQ 1. Does a higher EER necessarily mean a higher IEER? No, EER is the rated point, while IEER takes into account multiple segments of partial load. There is no absolute direct proportion between the two. 2. Is it necessary to refer to IEER parameters for industrial projects? In scenarios of long-term partial load operation, the reference value of IEER is higher than the rated EER. 3. Will the IEER value decrease under the 55℃T3 condition? As the temperature rises, IEER also decreases synchronously. Selection requires reference to the parameters of the high-temperature working condition. 4. Will the N+1 parallel connection system increase the IEER? Reasonable linkage control and maintaining a high load rate during partial load can optimize the system energy efficiency. 5. How does fouling of the heat exchanger affect partial load? The heat transfer deteriorates, the high and low pressure shifts, and the partial load energy efficiency decreases more significantly than the full load. 6. Can the performance interpolation table be used in the design institute's simulation software? Yes, the parameter format can be adapted to mainstream energy consumption simulation software. 7. Will there be differences between the partial load of the third-party report and the actual situation at the site? The laboratory ideal conditions, while the site is slightly affected by piping and installation conditions.
