Introduction
1. Background and significance of standard revision
According to the requirements of the Ministry of Housing and Urban-Rural Development's "Notice on Issuing the 2015 Engineering Construction Standards and Specifications Formulation and Revision Plan", the China Coal and Salt Construction Association organized relevant units to revise the original national standard "Design Code for Heating, Ventilation and Air Conditioning in Coal Industry" GB/工50466-2008. This revision extensively investigated industry practical experience, absorbed new technological achievements, and focused on implementing national energy-saving and environmental protection policies to ensure the scientificity, advancement and practicality of the standard.
2. Main revisions to the standard
| Chapter | Before revision | After revision |
|---|---|---|
| Scope of application | Applicable to coal mine shafts and auxiliary facilities | Added requirements for the overall planning of mining areas and special areas |
| Heating calculation temperature | Uniformly adopt the 18°C standard | Regional adjustment, increase to 20°C in extremely cold areas |
| Heat medium parameters | Hot water does not exceed 85°C | Add heat pump heating, water supply temperature should not be higher than 60°C |
3. Standard framework comparison
The new standard adds a new chapter "Heat source and cold source" in the chapter division, and adjusts the contents of "Domestic heating" and "Well antifreeze". The following is a comparison of the main frameworks:
- Heating: Add technical requirements for heat pump heating
- Ventilation: New regulations for emergency ventilation systems
- Air conditioning: Optimize air conditioning system design principles
4. Implementation suggestions
To ensure the effective implementation of the new standard, the following suggestions are put forward:
- Strengthen the promotion and implementation of the standard and organize industry training.
- Optimize equipment selection and adopt high-efficiency energy-saving technology.
- Improve the monitoring system and strengthen operation management.
- Establish a feedback mechanism and revise the standard in a timely manner.
