                With seven years' consecutive statistic and analysis, the sales of China gas water heaters/heating boilers kept high growth rate of 20-35% before 2014, but only 7.9% in 2014. The whole domestic economy development slowed down in 2015, which impacted the sale of gas water heaters to decrease by 1.8% to 1,610,000 units compared with the same period of 2014, with the import accounting for 27%. The sales of condensing gas heating boilers reached 85,000 units in 2015, accounting for 5% of the total.

                Training course: HVAC in healthcare industry
                With the development of medical technology and control theory, the operating rooms in China and worldwide developed rapidly and new type of operating rooms and auxiliary buildings are emerging. New requirements and evaluation methods are needed to accurately control the environment of operating room, including layout, system and medical equipments, which have become the difficulties for designers, researchers and engineers, especially the implementation of "Architectural technical code for hospital clean operating department" (GB 50333-2013). How to properly understand the concept of the code, legitimately interpret and implement measures do require the further study and improvement.
