For example, in aerospace material testing, continuous operation is required1000The controller can automatically record the temperature and humidity curves of each cycle during the hourly temperature and humidity cycle test, and achieve remote monitoring through a local area network. In terms of safety, the equipment integrates over temperature protection, leakage protection, compressor overload protection, and emergency stop button to ensure the safety of operators and samples. A certain electronic manufacturer has provided feedback that their equipment is operating3No malfunctions have occurred over the years, resulting in reduced annual maintenance costs40%.

5、 Energy Efficiency Optimization: Coordinated Use of Environmentally Friendly Refrigerants and Multiple Compressors

In response to the problem of high energy consumption of traditional equipment, the laboratory adopts a multi compressor collaborative refrigeration system, which automatically switches the compressor operation mode according to the temperature range. for example, in-40℃When conducting the following low-temperature tests, activate the binary low-temperature circuit system and combine it with an environmentally friendly refrigerant (such asR404A）Compared to single compressor equipment, it is more energy-efficient30%According to calculations by a certain new energy enterprise, the annual electricity consumption of its large-scale laboratory is12Ten thousand degrees reduced8.4Ten thousand kilowatt hours, saving electricity costs annually and exceeding the limit5Ten thousand yuan.

Large scale walk-in high-low temperature laboratories have been widely used in fields such as durability testing of automotive components, high-temperature aging of electronic components, temperature cycling testing of building materials products, and reliability verification of medical devices. For example, a leading car company uses this equipment modelExtreme temperature range of -40 ℃ to+85 ℃Environment, verify its electric performanceSUVThe thermal runaway protection performance of the battery pack increases the product's pass rate from78%upgrade to95%Significantly shortened the research and development cycle.

Conclusion

Large scale walk-in high and low temperature laboratories have become the core equipment for environmental simulation in the industrial field due to their spatial flexibility, precision control, functional scalability, and energy efficiency optimization. With the rapid development of intelligent manufacturing and new material technology, this equipment will continue to iterate, providing more efficient and economical solutions for product reliability verification.
