Where are the main reasons for the high energy consumption of air conditioning system in textile industry?
First, enterprises pay too much attention to assessment indicators, which leads to unnecessary increase in energy consumption.
On the other hand is the problem of the equipment itself, such as the energy consumption of the equipment itself is too high or the equipment is too old, resulting in reduced efficiency and high energy consumption.
The third aspect is mainly the detail management, such as the scale of the air conditioning room is not cleaned in time leading to the decline of efficiency, there is no reasonable use of cold and heat sources.
The selection of air conditioning assessment index in textile industry is too dead, and the selection of assessment index is unreasonable. There are mainly two aspects:
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 of cotton spinning workshop in summer is generally controlled in 28 ~ 32℃, and in winter it is generally controlled in 18 ~ 23℃. But many textile factories one-sided pursuit of process assessment indicators, the indicators set too high, too dead: summer one-sided requirements of temperature to low to a certain value below, winter workshop temperature is higher than a certain value, this kind of high requirements for indicators directly lead to the increase of energy consumption, it is estimated that every summer reduced once, air conditioning energy consumption to increase by 10%. For air conditioning load, the actual load of textile enterprises in each period of the year is different, generally speaking, the highest load in summer, so theoretically, the air conditioning load in each period should be calculated by unsteady heat transfer to flexibly control the temperature and humidity of the workshop to reduce energy consumption. But generally textile mills design air conditioning load with stable heat transfer, air conditioning system always operates under the condition of maximum energy consumption, which results in the waste of air conditioning energy consumption
Unreasonable condition of air conditioning equipment in textile industry
The unreasonable condition of equipment mainly refers to the aging of equipment, equipment itself energy consumption is too high, many large textile enterprises air conditioning equipment is mostly assembled in the 1990s, so all aspects of performance have a certain degree of backward, air conditioning system inside the old fan, water pump, nozzle, not only high energy consumption and treatment effect is not good. In fact, high energy consumption of fans and water 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 pump equipment in our country, and concluded that the power consumption accounts for about 50% of the industrial power consumption, which shows the unreasonable influence of the equipment itself on energy consumption. At present many textile enterprises in our country still use the old fashioned Y series axial flow fan inside the air conditioning system, air volume is small, power consumption, low efficiency, the cost of belt operation is relatively high; The old water pump has high head and high energy waste. The old nozzles require high pressure and poor atomization effect. Therefore, it is necessary to transform the existing old and high energy consumption fans, water pumps and nozzles into new and energy-saving equipment.
Textile industry air conditioning equipment management
Inadequate equipment management can also lead to excessive energy consumption. For example, in the north of our country because of the water hardness is too high, the water baffle in the water jet chamber is easy to form scale, if not cleaned in time it is apt to cause the air passage between the baffle to decrease, so that the resistance of the air through increases, which causes energy consumption to increase; In addition, if the maintenance of fans, water pumps and other parts is not timely, the performance of the equipment will be reduced, resulting in high energy consumption.
Through the above analysis, we will find that the energy consumption of air conditioning system is too high, whether from the perspective of assessment indicators or from the perspective of the equipment itself. Therefore, we can make targeted improvements in many aspects to reduce energy consumption.
