But meanwhile, as a large-size state-owned enterprise, FAW JIEFANG is very strict about technical modification projects in terms of technical demonstration. Finally, the thermal energy-recovery technology of Atlas Copco’s air compressor becomes the final choice of customers in replace of the initial solar-heating program.

On May 2010, FAW JIEFANG Qingdao Auto Factory planned to build bathrooms for staff workers and the planner in his experience chose the solar-heating program under the FAW JIEFANG’s requirements for energy saving. Accordingly, Atlas Copco suggested the recovery of thermal energy by air compressor through careful calculation and sound program design, and made detailed comparison with the solar-heating program.
