So how to choose and use can not only meet the product quality requirements but also meet the national energy conservation and emission reduction policy requirements? Analysis of textile industrial air conditioning manufacturers in the future textile plant air conditioning energy saving development direction.
1. Reasonable design and layout of air conditioning system
After determining the type of air conditioning, power and air supply, the design and layout of the air conditioning system will determine the energy consumption level. The location of the air conditioning room should be selected to shorten the length of the return air pipe as much as possible. And the use of the same section (the wind speed at the entrance of the return air chamber is 8-10 m/s) to design the air duct return air duct according to the economic wind speed (the wind speed at the entrance of the air supply pipe is 7 meters)/second) the design of the air supply system and the reasonable setting of the air speed of the air conditioning shower room provides the possibility to improve the effective utilization efficiency of the air conditioning.
2. Choose the type of air conditioning room reasonably
Conventional air-conditioned rooms use ordinary axial flow fans to provide air and rely primarily on a spray system for humidification. The humidification function of the new air conditioning room is realized under the full function air conditioning system. In the deployment of full-function air conditioning system, spray axial flow fan can not only meet the requirements of air supply, but also has humidification function. The two cooperate with each other, to achieve spring, autumn, winter three seasons do not spray water. Compared with the traditional air-conditioned room, it can save 20-40% energy. In summer, using cold water with low humidity or installing a row of sprayers can save 10 to 15 percent of energy, with annual savings of about 30 percent.
It is understood that in the spinning workshop of a textile enterprise in Shandong province, the air-conditioning room system is equipped with a full-function air-conditioning system, and equipped with spray axial flow fan. After production, the relative humidity of the workshop is about 70%, and the temperature of the workshop is 26-28℃ in summer and 23-25℃ in winter. After the transformation, compared with the traditional spray air conditioning system, the annual energy saving can be 20%.
3. Reasonable selection of air conditioning system equipment
Instead, a new type of spray axial fan is used, which reduces or eliminates the spray system and greatly reduces the energy consumption of the air conditioning room. A spinning company with 200,000 spindles in Shandong province has 14 air conditioning systems in its workshop. The FZ axial fan in 5 sets of system was modified and SZ energy-saving axial fan was used. After the transformation, each fan can save 6.31 kW of energy on average, accounting for 20.99%. The five air-conditioning systems will save energy and about 260,000 kWh a year.
Most of the spray rooms of the textile air conditioning system use swirl nozzles. The water droplets injected by the nozzle are characterized by smaller water droplets, larger injection angles and lower injection pressures. Therefore, when choosing the pump, the pump lift should not be too high. A large range of 22 to 28 meters is a relatively reasonable range to avoid the phenomenon of large carts and small carts. By setting the reasonable length of the shower room, the heat exchange between the air and the atomized water curtain can be ensured, so as to further improve the air conditioning capacity.
The return air filtration system can adopt disc filter or rotary cage filter according to the specific situation of the workshop, and can be reasonably set as ground return air or side wall concentrated return air according to the needs of the workshop, or a combination of the two ways. Reasonable selection of return air filter equipment can be conducive to air conditioning energy saving.
4. Operation and management of air conditioning system
Different production processes have different requirements for the temperature and humidity of the air conditioning system. It is well known that the installed capacity of the workshop and the temperature and humidity of the workshop are the two main bases for the design of textile air conditioning system. Therefore, determining the appropriate temperature and humidity for the process production requirements is critical to the configuration of the air supply for an air conditioning system. According to the different types of workshop and production varieties, the reasonable setting of air supply and air conditioning temperature and humidity is not only conducive to improving the quality of products, but also has a positive role in improving the efficiency of air conditioning.
In addition, the air supply volume of the air conditioning system in the textile factory is determined according to the peak temperature in summer. In other seasons, the air supply volume will be greater than the actual required air volume, which puts forward new requirements for the operation of the fan. Because of the successful application of variable frequency motor in air conditioning system, the operation of the fan can be continuously changed, and the return air of the fan can be adjusted at any time.
At present, according to the different needs of textile enterprises, the fan market is divided into different types of fans, such as axial flow fans, centrifugal fans, dust exhaust fans, spray axial flow fans and textile host fans. They are textile air conditioners. The energy saving of the system provides more space for device selection.
