GB/T 44544-2024 in English

1. Background of standard formulation and analysis of technological evolution

As the world's attention to air quality continues to increase, especially after the COVID-19 pandemic, air disinfection and purification have become an important part of public health. The GB/T 44544-2024 standard is formulated to standardize the technical requirements of sterilization and toxicity air conditioning units to ensure their effectiveness and safety in various scenarios. Sterilization and toxicity air conditioning units achieve indoor air sterilization and disinfection through physical and chemical methods, and also have air conditioning functions.

2. Comparison and dimensional analysis of standard frameworks

For example, Appendix A specifies the test method for PM0.3+ purification efficiency, requiring that the test be conducted within the applicable area of the unit to ensure its ability to remove fine particles.

4. Implementation suggestions and practical applications

4.1 Equipment selection suggestions

When purchasing a sterilization and virus removal air conditioning unit, you should consider its applicable area, energy efficiency ratio and purification efficiency. Give priority to products with self-cleaning function to reduce internal microbial contamination.

4.2 Installation and maintenance suggestions

During installation, ensure that there is enough space around the unit, and clean and replace the filter regularly. Refer to GB/T 18883-2022 "Indoor Air Quality Standard" to optimize the installation layout and improve the overall purification effect.
