Energy and water saving in spinning and weaving mill's airconditioning.

Optimizing Spinning and weaving Mill Air-Conditioning Systems for Significant Cost Savings. There are following areas which can give hand some savings. 1- Water saving, (about 10 to 15000 liter/month) 2- Expected Kw saving is about 150 kw. 3- Cleaning showering nozzle can reduce pump running time and saves kw. 4- Proper setting of Rh controller can reduce pump running time. 5- Using fresh and return air properly can save Pump running time.

Normally hot exhaust air is being used only in winter to increase department’s temperature Without getting cleaned by showering because in winter only 20% pump sprays water rest goes without any water treatment. This saves only air heating cost, because of supplying it through supply fan. Which is due to design of plant and by altering in design it will save whole the year. This exhaust air is being thrown whole the year without consuming in a way that would reduce a significant amount of supply air cost. There are two types of air, the Blow Room and carding filters are removing from department and this air removal consumes electricity. One type is the filter air, being used to suck the dropping, licker in and card fly which is any how necessary but there are air of condensers, fans sucking air from machines is also going into the filter and filter has to use power in throwing out. The condensers and fan’s air have their own significant throwing power so its pipes can be taken out from filter and should be exhausted via another room, cleaned there and its exhaust would be thrown without needing any extra radial fan power. By taking out these self throwing fan’s air can increase Filter pressure or reduce energy consumption. Introduction: Effective air-conditioning is essential for maintaining optimal humidity (RH%) and temperature in spinning and weaving mills. However, significant energy and water wastage occurs due to inefficiencies in current systems. By better understanding the showering system technology and implementing water-saving alternatives, mill owners can achieve substantial energy and resource savings.(about 10 to 5000 liters of water can be saved monthly). Key Insight: By optimizing the water usage for air-conditioning in spinning mills, particularly in Open-End (OE) spinning, mills can save up to 80 kW of energy. For instance, reducing the chiller’s load minimum by 50% in OE spinning alone can lead to a 50 kW energy saving. The Problem: In typical OE air-conditioning systems, 30 kW pumps (15 kW each) are used to push water through shower nozzles. These pumps lift about 250 gallons of water per minute, but only a small portion is needed for air cooling. The excess water falls back into the tank, leading to unnecessary energy and water use. Additionally, these systems require large water tanks (2,000 to 3,000 liters), which must be chemically treated and drained monthly, leading to water wastage of over 10,000 liters per mill. Proposed Solution: There are more efficient and cost-effective methods to maintain desired humidity and temperature in mill environments without relying on large pumps and excess water. For example, instead of using 30 kW pumps, smaller systems with misting nozzles and a minimal amount of water can achieve the same results. Misting Systems: Modern misting systems can replace traditional showering nozzles. These systems atomize water into fine droplets that evaporate quickly, cooling the air more efficiently. Earlier misting systems failed due to nozzle clogging, but the issue has been resolved by using larger orifices (greater than 1 mm). Advantages of Misting Systems: 1. Energy Efficiency: Eliminates the need for 15 kW inverters, pumps, and other equipment like headers, about 24 Pvc pipes, 144 showering Nozzles, significantly reducing energy consumption. 2. Water Savings: Avoids the use of large water tanks and eliminates the need to drain 2,000-3,000 liters of water monthly, saving over 15,000 liters annually per mill. 3. Lower Maintenance: Fewer mechanical components like pumps, headers, and nozzles mean reduced maintenance costs and fewer parts to replace. Conclusion: By adopting modern misting systems and reducing the reliance on large water pumps, mill can achieve substantial savings in energy and water usage. This not only lowers operational costs but also supports more sustainable practices in the textile industry.
