Cultural relics are divided into inorganic relics and organic relics, which have different requirements for temperature, humidity, light level, atmospheric environment and biological factors. Since different cultural relics have different requirements for temperature and humidity, it is crucial to choose professional equipment that can control temperature and humidity at the same time for cultural relics protection.

Constant temperature and humidity air conditioner, integrating dehumidifying and humidifying functions, can achieve accurate and reliable constant temperature and humidity control, with a humidity control range of 30-80%RH and a temperature control range of 10-30℃. Temperature control accuracy ±1℃, humidity control accuracy ±5%RH.

Applied to the museum, collection room, antique cultural relics storage room dedicated constant temperature and humidity environment to create.

Cultural relics in the preservation process is very susceptible to environmental factors, changes in the environment will cause deterioration or damage to cultural relics. Even if preserved in the museum, outside temperature, humidity, light, air pollutants, harmful organisms and other factors will slowly damage the cultural relics. Environmental factors have become the main cause of damage to artefacts in museum collections.

Cultural relics collection in the preservation of some of the requirements of storage: due to the cultural relics collection of a variety of different textures, performance is different, so their preservation requirements are not the same. Therefore, according to the performance of the collection, targeted measures to do a good job in the collection of custody, storage work.

Temperature and humidity: In order to keep the collection in good condition for a long time, suitable temperature and humidity are indispensable conditions.

Generally speaking, 15 ~ 18 ℃ humidity and 50 ~ 65% relative humidity is more suitable for all kinds of items.

Harmful gases and dust: Pollution in the air is very serious in modern society. When the atmosphere contains traces of ozone, it can oxidise metals such as copper, iron and lead, and make the pigments on fabrics, paper and colourful paintings fade or change colour. Many harmful gases, such as coal, rotten food and toilets emitted hydrogen sulfide (rotten egg smell) gas on silver, copper and lead are harmful; chlorine can make the dyes fade to colourless, fabrics, paper and leather, etc. have a destructive effect, and cause corrosion of metals; aeroplanes, automobiles, smokestacks, coal stoves, etc., a large number of carbon dioxide emissions, not to mention.

The air is often mixed with very fine hard particles, they land with moisture and deposited on the items, easy to bacteria and mould and other microorganisms parasitisms, on a variety of organic texture of the collection of the harm is particularly great. In order to prevent the impact of harmful gases and dust on the collection, the collection should be placed in a place where the air is relatively fresh, to minimise soot and faecal odour and other possible damage to the collection.

Effective way to prevent mould growth is natural ventilation, and find ways to eliminate the indoor mould environment. Items that have been found to have mould should be disinfected.
