What Are the Contents and Requirements of GB19153 Standard for Energy Efficiency Testing of Air Compressors?

Time:2026-05-07 15:51:12

1、 Standard Overview

GB 19153-2019 "Minimum Allowable Values and Energy Efficiency Grades for Positive Displacement Air Compressors" (implemented on July 1, 2020) is a mandatory national standard, which focuses on controlling the energy efficiency of air compressors through the classification and admission of unit specific power (kW/(m ³/min).

2、 Scope of application (covering main models)

Model	Power Range	Output Pressure
General used oil injection rotary (screw/single screw/slide/vortex)	1.5～630kW	0.25～1.4MPa
Variable speed (frequency conversion/permanent magnet frequency conversion) fuel injection rotary screw	2.2～315kW	0.25～1.4MPa
General used reciprocating pistons	0.75～75kW	0.25～1.4MPa
Oil free reciprocating piston	0.55～22kW	0.4～1.4MPa
Directly connected portable reciprocating piston	0.55～22kW	0.25～1.0MPa

3、 Definition of Core Terms

Unit volumetric flow rate: actual displacement under standard suction conditions (m ³/min).

Unit power: The total electrical power input to the compressor (excluding post-processing equipment).

Unit specific power: Unit power ÷ Unit volumetric flow rate (core assessment indicator, the lower the value, the more energy-efficient it is).

Energy efficiency level: divided into level 1 (highest), level 2, and level 3 (entry threshold).

4、 Energy efficiency rating and limit values

Special rules for frequency converters: Weighted specific power is calculated based on 25%/50%/70%/100% load weighting, with 70% load having the highest weight (0.4); The minimum air volume greater than 40% of full load is evaluated according to the fixed speed machine.

5、 Calculation Method (GB/T 3853 Execution)

Test parameters: Simultaneously measure volumetric flow rate, input power, exhaust pressure, suction temperature/humidity, and instrument accuracy meets GB/T 3853.

Specific power calculation: eVC=P/q (P=unit input power, q=volumetric flow rate).

Weighted formula for frequency converter: eVC (weighted)=0.1 × eVC25%+0.2 × eVC50%+0.4 × eVC70%+0.3 × eVC100%.

6、 Meaning of rules

Production end: forcing enterprises to upgrade their designs (such as high-efficiency hosts, permanent magnet motors, and variable frequency control) and eliminate inefficient production capacity.

User side: When purchasing, equipment can be selected according to energy efficiency levels, significantly reducing long-term electricity costs.
