Compliance overview
Scope and applicability
This standard specifies the safety requirements for lithium bromide absorption water chiller (heater) units. It applies to steam and hot water type lithium bromide absorption water chillers, as well as direct-fired lithium bromide absorption water chiller (heater) units. Other similar type units can refer to this standard for safety compliance. It is essential for manufacturers of commercial and industrial HVAC absorption equipment.
Technical requirements
The standard outlines mandatory safety requirements covering mechanical, electrical, and fire/explosion hazards. For the unit body, it mandates that operating pressures remain below local atmospheric pressure, and materials must possess adequate mechanical, thermal, and corrosion resistance. Manufacturers must ensure environmental and personal safety even under abnormal internal pressure rises. For electrical equipment, the standard requires insulation resistance above 1MΩ, reliable grounding, and overcurrent protection. Components must operate reliably within 90%-110% of rated voltage and feature acoustic/optical alarm ports for abnormal safety conditions. Electromagnetic compatibility must comply with the referenced GB/T 5226.1 standard. The combustion equipment system requirements are extensive, covering fuel piping, combustion control, and burner safety. It specifies that fuel cut-off valves must not leak, and emergency fuel supply cutoff must be rapid. Combustion control programs must include pre-purge and post-purge procedures to prevent furnace explosions. Flame detectors and automatic ignition systems must be highly reliable and protected against misoperation. Regarding safety protection components, the standard details a comprehensive list of mandatory devices based on the heat source type (gas, oil, steam, hot water). This includes generator pressure/temperature controllers, pump overload protection, and exhaust temperature monitors. Units must be equipped with interlock interfaces for remote monitoring and safety control.
Testing methods
The standard mandates several key testing procedures to verify compliance. Hydrostatic pressure tests are required for the heat source side tubes according to GB 151. Electrical safety is verified through insulation resistance tests and dielectric voltage strength tests. Fuel piping systems must undergo strict gas tightness and pressure resistance tests using inert gases. Additionally, combustion equipment must pass nominal combustion, ignition, and safety device action tests to ensure stable and safe operation.
FAQs
What products are regulated under GB 18361-2001?
GB 18361-2001 applies to steam and hot water type lithium bromide absorption water chillers, as well as direct-fired lithium bromide absorption water chiller (heater) units. Other similar type units can refer to this standard.
Are there any updates from the previous version of GB 18361-2001?
This standard was established based on the previous industry standard JB 8656-1997, which was abolished upon the release of this standard. It also references relevant safety standards from the Japan Refrigeration and Air Conditioning Industry Association.
How does GB 18361-2001 relate to international standards?
GB 18361-2001 is a dedicated Chinese national standard focusing specifically on the safety requirements of lithium bromide absorption units. It heavily references international and equivalent standards such as ISO 5149:1993 (for mechanical refrigerating systems safety) and IEC 204-1:1992 (for electrical equipment of industrial machines), while adding specific national requirements for direct-fired combustion systems.
