During the manufacturing process of the paper, the machine’s heat is large, which is easy to cause local high temperature and low humidity. The paper is very sensitive to the humidity of the air, and it is easy to absorb or dispel water. , Damage and other phenomena. While traditional mechanical refrigeration reduces the temperature, it also reduces environmental air humidity. Generally speaking, in order to ensure the temperature and humidity requirements of the working area, the humidifier is needed. If the mechanical refrigeration increases additional humidity load, it is waste of energy.

When printing objects, the viscosity of the ink changes with the temperature. The higher the temperature, the smaller the viscosity, and the appropriate viscosity, which directly affects the transfer of ink, the solid level of the imprint, the amount of ink penetration, and the gloss of the print. After a large amount of ink melting the temperature, the temperature is high, the heat is high, and the environmental condition of the local low humidity is prone to the phenomenon of dry and dry, ink seal falling off; high -temperature and dry air will cause problems such as paper damage, paper deformation, unprepared overprinting, and electrical electricity. , Directly affect production efficiency. In addition, the printed readings need to be cut and stored under the conditions of a certain environmental humidity, and the temperature and humidity of the environmental air should be equally important.

It can be seen that temperature and humidity control is one of the important factors affecting the production efficiency of paper mills and printing plants. The evaporation and cooling technology can meet the needs of cooling and humidifying at the same time. While solving the temperature requirements of the working area, the special humidity requirements of paper mills and printing plants can bear some wet loads (no need to add humidifiers) to achieve “one fell swoop”. Effects, and the initial investment and operating costs are lower than that of mechanical refrigeration, which ensures production efficiency and complies with the relevant policies of national energy conservation.

At present, the evaporation and cooling technology has been promoted and applied in the papermaking and printing industry. Its main way is to connect the air pipe of evaporate air -conditioner to provide local and environmental air to ensure indoor temperature and humidity.
