Alcance y aplicabilidad

This standard applies to displacement air compressors driven by electric motors, encompassing oil-injected rotary, variable speed rotary, and reciprocating piston types. It covers specific motor power ranges from 0.55 kW up to 630 kW and discharge pressures from 0.25 MPa to 1.4 MPa. Manufacturers of these air compressor categories must comply with this standard to access the Chinese market. It does not apply to compressors outside these specified power and pressure ranges.

Requisitos técnicos

The standard classifies energy efficiency into 3 grades, where Grade 1 represents the highest efficiency. It establishes the minimum allowable values of energy efficiency (Grade 3) that act as mandatory market access thresholds. The core metric used for evaluation is the package specific power, calculated as the ratio of package power to package volume flow under specified operating conditions. For variable speed air compressors, the standard introduces a specific evaluation method. Instead of a single measurement, the package specific power is calculated using a weighted average across 100%, 70%, and 40% of the full-load volume flow. This ensures that energy efficiency is accurately assessed across variable operating conditions rather than just peak load. Additionally, the standard provides informative guidelines in its appendix for converting the package specific power into isentropic efficiency and work transmission efficiency, referencing GB/T 3853 for foundational acceptance test parameters.

Métodos de ensayo

Testing must be conducted according to the methodologies outlined in GB/T 3853. The standard specifies rated operating conditions including an absolute suction pressure of 0.1 MPa, suction temperature of 20°C, and 0% relative humidity. Measurements must be taken within an intake temperature range of 5°C to 40°C. For variable speed rotary compressors, testing requires measuring the package specific power at 100%, 70%, and 40% load capacities, applying specific weighting coefficients (25%, 50%, and 25% respectively) to determine the final weighted efficiency value.

Preguntas frecuentes

What products are regulated under GB 19153-2019?

The standard regulates various types of displacement air compressors, including general oil-injected rotary compressors, variable speed oil-injected rotary compressors, general reciprocating piston compressors, oil-free reciprocating piston compressors, and direct-coupled portable reciprocating piston compressors.

Are there any major updates from the previous version of GB 19153?

Compared to the 2009 version, this edition adjusts the scope, introduces definitions for variable speed air compressors, improves energy efficiency metrics for certain products, and adds evaluation criteria and weighted calculation methods specifically for variable speed oil-injected rotary compressors.

How does GB 19153-2019 handle testing and calculation methods?

The standard references the methodologies specified in GB/T 3853 for displacement compressor acceptance tests. It defines specific rated operating conditions (such as 0.1 MPa absolute suction pressure and 20°C suction temperature) and introduces unique weighting coefficients for testing variable speed compressors at partial loads.
