3. Interpretation of the core content of the standard
3.1 Environmental condition requirements
The automatic demand response terminal of the centralized air-conditioning system needs to adapt to a variety of environmental conditions, which are specifically classified as follows:
| Place type | Level | Air temperature (℃) | Maximum change rate (℃/min) | Relative humidity (%) | Maximum absolute humidity (g/m³) |
|---|---|---|---|---|---|
| Shielding | C1 | -5～+45 | \n0.5 | 5～95 | 29 |
| C2 | -25～+55 | 0.5 | 10～100 |
4. Implementation Suggestions and Precautions
4.1 Equipment Selection Suggestions
When selecting a demand response terminal, focus on the following aspects:
- Communication interface compatibility: Ensure support for mainstream protocols such as Ethernet and LonWorks.
- Collection accuracy and frequency: It is recommended to use high-precision sensors with a minimum interval of 10 seconds.
- Security: Select a hardware security module certified by the State Cryptography Administration.
4.2 System Integration Precautions
During the system integration process, it is recommended to take the following measures:
- Data consistency management: Ensure data synchronization between devices.
- Emergency plan formulation: Plan response strategies in advance for extreme weather or equipment failures.
- Regular maintenance and updates: It is recommended to perform system inspections and firmware upgrades every quarter.
