Description
Technical Field
The invention relates to a temperature and humidity control system, in particular to a system suitable for accurately controlling the temperature and the humidity in a local range of a textile workshop, and belongs to the technical field of textiles.
Background
Because the chemical molecular structure of the cotton fiber contains hydrophilic groups of hydroxyl, carboxyl and acylamino, the hydrophilic groups are mainly combined with water molecules by hydrogen bonds, so that the water molecules lose the movement capability and depend on the fiber, and the water molecules have polarity, so that the water molecules can adsorb the water molecules, which is the moisture absorption and release principle of the cotton fiber. Since the relative humidity of air is in direct proportion to the moisture regain of cotton fibers, and the temperature is in inverse proportion to the moisture regain, whether the cotton fibers absorb or release moisture in the air has a direct relationship with the temperature and humidity of the air.
Therefore, in the textile production process, the air temperature and humidity in the textile workshop have great direct influence on each process of the textile production process and are one of five major factors influencing the textile production, the temperature and humidity are improperly or unstably regulated, the moisture regain of cotton rolls, roving and the like is unstable, carding difficulty in the cotton carding process can be caused, impurities and short fibers of raw cotton neps are increased, quality problems such as difficult drafting, dry cotton neps, poor neps and the like can be caused to the processes of doubling, twisting and the like, and therefore the quality of finished yarns is influenced and the broken ends of the yarns are increased.
In the prior art, air temperature and humidity in a textile workshop are controlled by utilizing an air conditioning engineering technology, and the air conditioning engineering becomes an integral important part of the textile industry. The air conditioning engineering usually takes the moisture regain of the stable cotton fiber as a reference, and correspondingly adjusts the air temperature and the relative humidity meeting the moisture regain index according to seasonal changes, so that the semi-finished product is properly dehumidified or absorbed in the production process, and the moisture regain requirement of the semi-finished product is met.
In order to ensure the air temperature and the relative humidity, a textile workshop is usually a relatively closed space, and an air conditioning project performs overall control on the air temperature and the relative humidity of the textile workshop in the whole closed space, however, the relatively closed textile workshop is usually large in space and poor in air circulation, and usually only one production line is arranged in the textile workshop, and usually a plurality of production lines are uniformly arranged side by side at intervals, taking a doubling process (or a yarn twisting process) as an example, a doubling frame (or a yarn twisting frame) is a whole doubling production line (or a yarn twisting production line) formed by a plurality of adjacently arranged doubling sets (or yarn twisting sets), and the whole doubling production line (or yarn twisting production line) is usually tens of meters long, so that the imbalance in the local range of the temperature and the humidity in the textile workshop is often caused by the relatively slow air circulation speed when the whole closed space is controlled by the air conditioning project, and accurate control on the air temperature and the humidity in the local range around the plurality of production lines cannot be realized.
