Industrial workshop air conditioning originated in the United States in the late 19th century, initially using water cooling technology. In the 1930s, American engineer Willis Carrier invented the first modern compression refrigeration air conditioning system. The development of industrial workshop cooling air conditioning in China began in the 1950s, with the introduction of foreign compression refrigeration technology starting in the late 1970s. In the 1980s, the first batch of enterprises specializing in the research and development and manufacturing of workshop cooling systems emerged in China. In the early 21st century, new energy technologies (such as solar energy and ground source heat pumps) and advanced cooling equipment (such as evaporative cooling systems) were promoted. Currently, the technology is mature and widely used in industries such as steel, chemicals, and logistics, as well as in outdoor engineering and sports venues.
The development history of industrial workshop air conditioning can be traced back to the United States in the late 19th century. At that time, some factories in the United States began to explore the application of refrigeration technology and air conditioning systems to enable employees to work in the high temperatures of summer.
Early workshop air conditioning systems used water cooling technology, where water was cooled by cooling towers and then piped to coolers in the workshop to dissipate cool air. This system was stable in operation but inefficient and required a large amount of water.
In the 1930s, American engineer Willis Carrier invented the world's first true air conditioning system. This system used compression refrigeration technology, achieving cooling by compressing and expanding the refrigerant. With the widespread adoption of this system, air conditioning in industrial workshops became widely used.
Since then, industrial workshop air conditioning has continuously developed and its technology has improved. Modern industrial workshop air conditioning systems can be precisely designed and configured according to factors such as workshop area, process requirements, and indoor temperature requirements, achieving advantages such as high efficiency, energy saving, low noise, and low maintenance costs.
The development of industrial workshop cooling air conditioning in China can be traced back to the 1950s, when some systems based on natural ventilation and water cooling began to appear for cooling factory workshops.
In the late 1970s, with the development of national economic construction, some large factories began to introduce advanced foreign compression refrigeration technology, making workshop cooling more effective and energy-efficient. In the 1980s, the first batch of enterprises specializing in the research, design, and manufacturing of workshop cooling systems emerged in China.
In the early 21st century, with rapid national economic growth and increased environmental awareness, industrial workshop cooling and air conditioning technologies became more advanced and their applications more widespread. For example, utilizing new energy technologies such as solar energy, ground source heat pumps, and wind power can provide more environmentally friendly and energy-saving solutions for industrial workshop cooling. Advanced cooling equipment for high-temperature and high-humidity environments, such as specialized evaporative cooling systems, direct evaporative air conditioning systems, and external evaporative air coolers, has also been widely adopted.
Currently, domestic industrial workshop cooling and air conditioning technology is quite mature and has been widely applied in key industries such as steel, chemical, and logistics. Simultaneously, some cooling equipment is gradually being applied to outdoor projects, sports venues, and other fields.
