In the modification of textile industrial air conditioning system, it is three important aspects of improving the heat and humidity exchange efficiency of shower room and reducing air conditioning system energy consumption, air conditioning system design, air conditioning equipment transformation, and air conditioning system. This paper introduces its theoretical analysis and engineering practice based on research project background. Let Jincheng Company to explain it.
Workshop cold load calculation
Heating and ventilation and air conditioning design specification, air-conditioning rooms are calculated in summer computation, which should be calculated in unstable heat transfer, but the textile factory generally adopts a stable heat transfer calculation. This method does not distinguish between heat and cold load, the calculated air conditioner is too large, resulting in excessive equipment capacity, enabling the equipment to operate at low efficiency, increasing energy consumption. Therefore, the cold load of the textile factory should be calculated according to the copy of the cold load, and the heat and cold load is strict, which is important in energy conservation.
Temperature and humidity base determination
In the summer, the temperature is reduced by 1 ° C, and the air volume per million cubic meters increases by about 1 kW, which is equivalent to air conditioning to increase by 50%. In winter, the temperature base decreases from 22 ° C to 20 ° C, and the heating load can be reduced by about 26% to 31%. Therefore, from an energy-saving angle analysis, the upper limit of the temperature base is selected, and the lower limit of the winter temperature base is selected. Cotton fibers are a hydrophilic fiber, and the relative humidity affects its performance in performance. In most parts of the summer, the relative humidity is large, so the base can take a higher value; it is suitable for a low value in winter.
Wind pass, fan improvement
Focus on the impact of the air-to-air in the air end speed comparison and the adjustment of the adjustment should be taken. In order to reduce the wind away from the wind, it is designed to convert all of the bargains, transform the original airway into an inorganic flame retardant glass flame, and use 980 mm × 800 mm, 980 mm × 600 mm, 980 mm × 400 mm three Size to increase the wind speed of the airway, increase the end of the end, solve the problem of uniform workshop, the end wind is not available.
Increase the fan flow by increasing the angle of the fan blade. Adopt a way to gradually increase the angle of the fan, and test the air volume, and monitor the power consumption power consumption until the motor power is close to full load. At this time, the fan flow reaches 115 × 105 m3 / h, compared to the increasing front fan flow. Increase 20% to meet the requirements of the system air supply. At the same time, adjust the axis center of the fan motor, as soon as possible, the edge of the fan blade is uniform, maintained within the specified 3 to 5 mm, and improve the fan efficiency.
