本标准规定了机械式、电子式家用和类似用途地暖设备用温度控制系统的安全要求。本标准包含对控制居室内地暖的温度控制系统的要求,也包含与管道泵、热水器、中央空调系统及楼宇自控系统等配套使用的地暖控温器系统的要求,还包含具有远程控制与智能控制功能的地暖控温系统的要求。本标准不包含对地暖辐射部分的要求。
本标准适用于额定电压不超过690V、额定电流不超过63A、对居室内由电能转换成热量(常称电地暖)或通过热流体介质扩散热量(常称水地暖)的、要求单一或双重温度控制的地暖控温系统。
Introduction
Background and significance of safety standards for floor heating temperature control systems
With the widespread use of floor heating in homes and commercial buildings, the importance of temperature control systems has become increasingly prominent. GB31459-2015 aims to ensure the safety, reliability and durability of these systems. The standard specifies in detail the technical requirements for various temperature control systems from electric floor heating to water floor heating, including functional safety, protection against electric shock and electromagnetic compatibility.
Comparison of standard frameworks
| Chapter | Overview | Key points of technical requirements |
|---|---|---|
| Chapter 4 General description of tests | Provisions on test conditions and number of specimens | Specify the test environment and specimen requirements to ensure consistency of results. |
| Chapter 8 Functional Safety Requirements | Temperature Control Function and Temperature Limit Protection | Maximum Set Temperature Limit (Electric Floor Heating: 50℃, Water Floor Heating: 60℃) |
| Chapter 23 Electromagnetic Compatibility Requirements | Emission and Immunity Test | Ensure the stable operation of the system in different environments. |
Technology Evolution Analysis
Transition from Mechanical to Electronic
Mechanical thermostats were once the mainstream, but with the advancement of electronic technology, electronic temperature control systems have gradually replaced mechanical ones due to their higher accuracy and intelligence. For example, electronic controllers achieve more stable temperature control through more accurate sensors and algorithms.
Implementation suggestions
- Choose a suitable temperature control system:Choose a temperature control system with corresponding functions according to the type of floor heating (electric floor heating or water floor heating) and the use environment.
- Ensure the correct installation location:In accordance with standard requirements, install the thermostat in a position that can accurately reflect the indoor temperature to avoid obstruction and heat source influence.
- Regular inspection and maintenance:Regularly check the operating status of sensors, wiring terminals and controllers to ensure long-term stability of the system.
- Follow standard test methods:During the procurement and installation process, refer to the test methods in the standard for verification to ensure that the product meets the requirements.
