Broad Group is a private manufacturer of central air conditioning non-electric absorption chillers that are powered by natural gas and waste heat based in Changsha, China.
[2] In the 1980s, most domestically manufactured boilers were of poor quality and had high risk of exploding, while Broad's did not.
At the time, the government provided incentives for non-electric chillers to relieve strain on the national electricity grid, contributing to the company's rise as it became the global leader in absorption chiller by sales in 1996; it entered the international market in 1998 and today, its sales in domestic and international markets split evenly.
[3] In 2015, BSB built a 57-storey Mini Sky City that stands at a height of 204 m.[4] The construction of the tower took just 19 days.
[4] Invented in 2009, the BSB achieves high energy efficiency and carbon reduction primarily through thermal insulation, preventing cool air from leaving indoors and hot air from coming in from outdoors when the weather is hot and vice versa when the weather is cold, and requires short construction time since parts are pre-fabricated in factories and assembled onsite.
