The Kadoorie Marble Building (now the Children's Palace of China Welfare Institute), located at Yan 'an West Road 164, was built at 1924, with a building area of 3300m2. It is the first central air-conditioned commercial building in China, using ammonia vertical 2-cylinder and 4-cylinder piston chillers from York Company.

The origin of air conditioning
Around 1000 BC, Persians had invented an ancient air conditioning system, which used wind poles installed on the roof to blow cold water into the room from the outside to make people feel cool indoors.
/kloc-in the 9th century, Michael Faraday, a British scientist and inventor, discovered that compressing and liquefying a certain gas could freeze the air. This phenomenon appeared when liquid ammonia evaporated, and his idea was still theoretical at that time.
1842 Florida doctor John Gorrie compressed a new building with central air conditioning. Alfred Wolff, an engineer in hoboken, New Jersey, helped design this brand-new air conditioning system and transferred this technology from textile mills to commercial buildings. He is regarded as one of the pioneers in reducing the temperature of the working environment.
In the late period of 1902, Willis Carrier (1876-1950) invented the first modern electric air conditioning system. The difference between its design and Wolff's design is that it can not only control the temperature, but also control the humidity of the air, so as to improve the quality of the production process of a printing factory in Bukling, new york. This technology provides a low-heat and low-humidity environment, which makes the paper area and ink arrangement more accurate.
Later, Carrier's technology began to be used in the workplace to improve production efficiency. 19 15 set up Carrier Engineering Company to meet the surge in demand. With the gradual development, air conditioning has been used to improve the comfort of home and car. The sales volume of residential air-conditioning system didn't really take off until 1950' s. The Royal Victoria Hospital in Belfast, Northern Ireland was built in 1906, which has special significance in architectural engineering and is known as the first air-conditioning building in the world.
