Embodiment Construction
[0021] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0022] Such as figure 1 As shown, the present invention provides a constant temperature control method for archives and warehouses, including a constant temperature zone, which is divided into a temperature rise zone 2, a temperature drop zone 1, a stop temperature rise zone 3, and a stop temperature drop zone 4, so as to obtain the temperature required by the environment. The upper limit Tuu, the lower limit Tdl of the environment that needs to be cooled, the lower limit Tsl of the temperature control equipment to stop the temperature rise, and the upper limit Tsu of the temperature control equipment to stop the cooling;
[0023] Obtain the current state of ...

The invention relates to a constant temperature control method for an archive storehouse interval. The constant temperature interval comprises a heating area, a cooling area, a heating stopping area and a cooling stopping area, so that an upper limit Tuu of heating, a lower limit Tdl of cooling, a lower limit Tsl of heating stopping and an upper limit Tsu of cooling stopping are obtained; the state of temperature control equipment and the environment temperature Tc of an archive storehouse are obtained; when Tc is larger than or equal to Tdl and the state of the temperature control equipment is not refrigeration, the temperature control equipment is started for cooling; when Tc is smaller than or equal to Tsu and the state of the temperature control equipment is not stopping, the temperature control equipment is stopped for cooling; when Tc is smaller than or equal to Tuu and the state of the temperature control equipment is not heating, the temperature control equipment is started forheating; when Tc is larger than or equal to Tsl and the state of the temperature control equipment is not stopping, the temperature control equipment is stopped for heating; otherwise, the temperature control equipment is kept in an original state. According to the method, the temperature change trend is predicted, and the temperature control equipment is started and stopped in advance, so that the continuous working and continuous stopping time of the temperature control equipment is prolonged, and the state alternating frequency of the temperature control equipment is reduced.
Description
technical field [0001] The invention relates to the technical field of temperature control, in particular to a method for controlling the constant temperature of an archive storeroom. Background technique [0002] Archives are the storage places for materials, books, cultural relics and other items. Temperature is one of the main factors affecting the deterioration of archive materials. Appropriate temperature can ensure the long-term preservation of archive materials. The constant temperature of the archive warehouse is between 14 and 24°C. [0003] Generally, multiple temperature control devices are placed in an archive warehouse. In order to adjust and maintain the indoor temperature in the target range, the existing technology usually uses the upper and lower limits of the temperature range as the start-stop threshold. When the temperature exceeds the range value, all the temperature control devices are immediately started to work. When the temperature enters the range,...
