Archives are centralized bases for preserving important records of the Party and the state, and are centers for utilizing archival information resources across the society. Archives work is a key component of China's archival endeavors. China has over 3,000 archives at various levels, which reflect the political, economic, military, and cultural life of different historical periods in the country. For many years, archives at all levels across the country have vigorously developed archival information resources, actively opened archives to the public, and provided archival services to support the overall work of the Party and the state as well as various societal needs. Depending on the type of collections and spatial zones, archives have strict control over air temperature and humidity. For the design of air conditioning systems in archives, the National Archives Administration issued the Archives Industry Standards of the People's Republic of China, DA/T 87-2021 "Design Specifications for Air Conditioning Systems in Archives" on May 26, 2021, which was officially implemented on October 1, 2021.

Archives storage rooms should maintain relatively stable temperature and humidity, with daily temperature fluctuations ≤ ±2°C and daily humidity fluctuations ≤ ±5%, hence, requiring constant temperature and humidity air conditioning systems. Traditional air conditioning systems typically use a heat pump-type chilled and hot water unit combined with a packaged air conditioning unit. The packaged air conditioning unit includes a humidifier and an electric heater. However, directly using the electric heater results in high energy consumption and is not energy-efficient. Therefore, SINO KING recommends using a four-pipe air-cooled heat pump unit combined with a packaged air conditioning unit. The four-pipe air-cooled heat pump unit has three operating modes: cooling only, heating only, and simultaneous cooling and heating. The packaged air conditioning unit includes an additional hot water heat exchanger which, as a substitute for the traditional electric heating system, can fully recover waste heat from condensation and use the heat as a reheat source after cooling and dehumidification. This makes the unit more energy-efficient and environmentally friendly.
