The high energy consumption of the air conditioning system in the textile industry is mainly due to the following reasons:
One is that enterprises pay too much attention to assessment indicators, which leads to unnecessary increases in energy consumption.
On the other hand, there is the problem of the equipment itself, such as the equipment itself consumes too much energy or the equipment is too old, resulting in reduced efficiency and high energy consumption.
The third aspect is mainly detailed management, such as the lack of timely cleaning of the scale in the air-conditioning room, resulting in a decrease in efficiency, and failure to use cold and heat sources rationally.
The choice of assessment indicators for air-conditioning in the textile industry is overwhelming, and there are two main reasons for the unreasonable choice of assessment indicators:
First, the selection of temperature and humidity assessment indicators is not flexible enough;
Second, the design index of air-conditioning load is too large. The temperature in the cotton spinning workshop in summer is generally controlled at 28~32℃, and in winter it is generally controlled at 18~23℃. However, many textile mills unilaterally pursue process assessment indicators, setting the indicators too high and too dead: in summer, the temperature is unilaterally required to be lower than a certain value, and the temperature in the workshop is required to be higher than a certain value in winter. This kind of high index is high. The requirements directly lead to an increase in energy consumption. According to estimates, for every degree reduction in summer, the energy consumption of air-conditioning will increase by 10%. Regarding the air conditioning load, the actual load of textile enterprises is different in each period of the year. Generally speaking, the summer load is the highest. Therefore, theoretically, unstable heat transfer should be used to calculate the air conditioning load in each period to flexibly control the temperature and humidity of the workshop to reduce energy. Consumption. However, general textile factories design air-conditioning load with stable heat transfer, and the air-conditioning system always runs under the highest energy consumption condition, which causes a waste of air-conditioning energy consumption.
Unreasonable condition of air-conditioning equipment in textile industry
The unreasonable condition of the equipment mainly refers to the obsolete and aging equipment, and the equipment itself consumes too much energy. Most of the air-conditioning equipment of many large textile enterprises was assembled in the 1990s, so all aspects of performance are backward to a certain extent. The old-fashioned fans in the air-conditioning system , Water pumps, nozzles, etc. not only consume high energy, but also have poor treatment effects. In fact, the excessive energy consumption of fans and pumps is not only prominent in the textile industry, but also in many other industries. The relevant state departments have made statistics on the power consumption of existing fans and pumps in my country and concluded that the power consumption is about 50% of industrial power consumption, which shows the impact of unreasonable equipment itself on energy consumption. At present, many textile enterprises in our country still use old-fashioned Y-series axial fans in the air-conditioning systems, which have small air volume, high power consumption, low efficiency, and high belt operation costs; the old-fashioned water pumps used have high lift and high energy waste; Old-fashioned nozzles require high pressure and poor atomization effect. Therefore, it is necessary to transform the existing obsolete, high-energy-consuming fans, pumps, and nozzles into new, energy-saving equipment.
Management of air-conditioning equipment in the textile industry
Imperfect equipment management can also lead to excessive energy consumption. For example, in the north of our country, due to the high hardness of water, scale is prone to form on the water retaining plate in the spray chamber. If it is not cleaned in time, it will easily cause the air passage between the baffles to decrease, thus increasing the resistance to air passage. If the maintenance of fans, water pumps and other mechanical parts is not timely, it will also reduce the performance of the equipment and cause excessive energy consumption.
Through the above analysis, we can find that the energy consumption of the air-conditioning system is too high both from the perspective of the evaluation index and from the perspective of the equipment itself. Therefore, we can strive to make targeted improvements in various ways to reduce energy consumption.
