Description
技术领域technical field
本发明涉及一种能源管理技术,特别涉及一种空调送风量与生产负荷布置协调节能方法。The invention relates to an energy management technology, in particular to an energy-saving method for coordinating the air supply volume of an air conditioner and the arrangement of production load.
背景技术Background technique
随着机械制造业大力发展及国家宏观调控投资政策对工业的大力支持,工业厂房建筑的设计量迅速增加。工业厂房的特点是建筑面积大,跨度大,高度高,建筑能耗巨大,其中空调能耗约占据整个建筑能耗的一半左右。因此对于大型机加工厂房内对其采取节能措施十分有必要。如图1所示某机加工车间生产设备布置平面图,机加工厂房内安有的是变风量单侧喷口远距离送风的空调系统,它通过空调送风量与生产负荷布置协调进行系统节能,因为空调系统是一个动态系统,负荷会随时发生变化,所以进行空调系统进行节能的核心在于变风量以及风量与生产负荷的布置进行协调来达到节能的目的。With the vigorous development of the machinery manufacturing industry and the strong support of the national macro-control investment policy for the industry, the design volume of industrial plant buildings has increased rapidly. Industrial plants are characterized by large building areas, large spans, high heights, and huge building energy consumption, of which air-conditioning energy consumption accounts for about half of the entire building energy consumption. Therefore, it is very necessary to take energy-saving measures for large-scale machine processing plants. As shown in Figure 1, the production equipment layout plan of a machining workshop, there is an air-conditioning system with variable air volume and single-side nozzle for long-distance air supply in the machining workshop. The system is a dynamic system, and the load will change at any time. Therefore, the core of energy saving in the air conditioning system is to coordinate the variable air volume and the layout of the air volume and production load to achieve the purpose of energy saving.
变风量空调系统是一种通过改变送风量来满足室内负荷变化的全空气空调系统。该系统具有良好的节能性和舒适性,满足用户对室内空气品质的良好要求,广泛用于写字楼、医院、图书馆和体育馆等各类建筑。The variable air volume air conditioning system is an all-air air conditioning system that meets the indoor load changes by changing the air supply volume. The system has good energy saving and comfort, meets users' good requirements for indoor air quality, and is widely used in various buildings such as office buildings, hospitals, libraries and gymnasiums.
对于传统的机加工车间来说,主要采用的是定风量空调系统。定风量空调系统一般维持全年的风量固定不变,并且根据空调房间最大热湿负荷进行送风量的确定,当空调负荷减小时通过调节送风温度来维持室内温、湿度,而采用变风量空调系统则根据房间温度参数的变化,通过变频调速装置调节风量。但实际情况是系统的运行满负荷时间相对较短,由于室外环境和室内生产负荷的变化,风机大部分时间处于部分负荷运行工况,且风机功率与转数的三次方成正比,由此可看出降低风机转速将带来的节能效果。显然采用变风量空调系统可以减小风机的功率损耗,大大节约风机全年能耗,达到节能的目的,提高空调系统的运行经济性。同时由于变风量空调系统是全空气空调系统,它可充分利用室外新风作为冷源。这样对于冷水机组来说,在使用室外新风作为冷源时期内,冷水机组可停止运行,依靠室外的天然冷源来提供冷源,这样使冷水机组能耗得以降低。因此对于大型机加工厂房来说采用变风量空调系统是优于定风量空调系统。For traditional machining workshops, the constant air volume air conditioning system is mainly used. The constant air volume air conditioning system generally maintains a constant air volume throughout the year, and determines the air supply volume according to the maximum heat and humidity load of the air-conditioned room. When the air conditioning load decreases, the indoor temperature and humidity are maintained by adjusting the supply air temperature, and the variable air volume is used The air conditioning system adjusts the air volume through the frequency conversion speed regulating device according to the change of the room temperature parameters. However, the actual situation is that the full load time of the system is relatively short. Due to changes in the outdoor environment and indoor production load, the fan is in partial load operation most of the time, and the power of the fan is proportional to the cube of the number of revolutions. It can be seen that reducing the fan speed will bring about the energy-saving effect. Obviously, the use of variable air volume air conditioning system can reduce the power loss of the fan, greatly save the annual energy consumption of the fan, achieve the purpose of energy saving, and improve the operating economy of the air conditioning system. At the same time, since the variable air volume air conditioning system is an all-air air conditioning system, it can make full use of outdoor fresh air as a cooling source. In this way, for the chiller, during the period of using outdoor fresh air as the cold source, the chiller can stop running and rely on the outdoor natural cold source to provide the cold source, so that the energy consumption of the chiller can be reduced. Therefore, the variable air volume air conditioning system is better than the constant air volume air conditioning system for large machine processing plants.
喷口送风是大空间建筑中使用最广泛的气流组织形式,根据建筑实际特征,一般将喷嘴安装于建筑某一侧墙面并且回风口布置与该侧墙上。对于一个空调系统,如果其系统运行良好则室内气流会分布均匀,从而避免了因温度不均而造成室内温度梯度大,局部过冷或过热的现象。但是这些问题却时常出现在变风量空调系统中。在变风量系统中,风量的减少会使风口送风参数发生改变,使得空调区的气流流场变得不理想。变风量空调系统在部分负荷运行工况下,由于送风量减小导致送风速度变小,送风射流容易受到“浮生力”影响,会产生冷风下坠和热风上浮的问题,且随着送风速度的进一步减小,射流弯曲的现象也愈发明显。这样的送风射流所形成的气流组织效果很差,也会使得部分区域的温湿度及速度不合理,从而使空调区内人员感到不合适。因此考虑到喷口送风射流规律的影响,当房间送风速度减小时,送风射流射程缩短,当房间送风量减小时将距离喷口远处生产设备关闭,距离喷口近处生产设备开启。Nozzle air supply is the most widely used form of airflow organization in large-space buildings. According to the actual characteristics of the building, the nozzle is generally installed on a certain side wall of the building and the air return port is arranged on the side wall. For an air conditioning system, if the system works well, the indoor airflow will be evenly distributed, thereby avoiding the phenomenon of large indoor temperature gradients, local overcooling or overheating due to uneven temperature. But these problems often appear in the variable air volume air conditioning system. In the variable air volume system, the reduction of the air volume will change the air supply parameters of the tuyere, making the air flow field in the air conditioning area unsatisfactory. When the variable air volume air-conditioning system is operating under partial load, the air supply speed decreases due to the decrease in the air supply volume, and the air supply jet is easily affected by the "floating force", which will cause the problem of cold air falling and hot air rising. As the wind speed decreases further, the phenomenon of jet bending becomes more and more obvious. The airflow organization effect formed by such air supply jets is very poor, and the temperature, humidity and speed in some areas will also be unreasonable, so that people in the air-conditioning area feel uncomfortable. Therefore, considering the influence of the air supply jet flow pattern of the nozzle, when the air supply speed in the room decreases, the range of the air supply jet will be shortened. When the air supply volume in the room decreases, the production equipment far away from the nozzle will be closed, and the production equipment near the nozzle will be turned on.

The production load is 100%, 75%, 50%, and 25% of the equipment Layout situation. Correspondingly different equipment layouts correspond to different production loads. As shown in Figure 1, a schematic diagram of the layout of production equipment in a machining workshop, 1 to 17 are CNC machine tools in the machining workshop. On the left side of the figure, there are 8 air supply outlets of the air conditioning system arranged at equal distances. In the workshop area, all 17 CNC machine tools are arranged in 5 rows. According to the numbering of the production equipment in the accompanying drawing 1, it can be seen that when the production load is 100%, it means that all the indoor machine tools are in production; when the production load is 75%, the fifth row of machine tools 17, 17, 16, 15 and the machine tool equipment 14 on the 4th row are not in production; The machine tools 10 and 9 on both sides of the third row are not in production; when the production load is 25%, the machine tools 4, 5, 6 in the second row indoors and the machine tool 9 in the middle of the third row are in production.

In conjunction with accompanying drawing 1, when determining the production load under different production equipment layouts, the specific implementation method of selecting the corresponding air supply volume is that in summer when the production load is 100%, all the machine tools are working, and the air supply volume is 24500m 3 /h, fresh air valve opening degree is 12.2%, when the production load is 75%, machine tools 17, 16, 15, 14 are not in production, the air supply volume is 22500m 3 /h, fresh air valve opening degree is 13.6 %, when the production load is 50%, the machine tools 17, 16, 15, 14, 13, 12, 11, 10, and 7 are not in production, the air supply volume is 20500m 3 /h, and the fresh air valve opening degree is 14.6% , when the production load is 25%, only 4, 5, 6, and 9 machine tools are in production, the air supply volume is 18500m 3 /h, and the fresh air valve opening degree is 15.7%; in winter, when the production load is At 25%, the air supply volume is 22500m 3 /h, and the fresh air valve opening degree is 10%. When the production load is 50%, the air supply volume is 20500m 3 /h, and the fresh air valve opening degree is 10%. When the production load is When the production load is 100%, the air supply volume is 16500m 3 / h, and the fresh air valve opening degree is 10%. In the specific implementation mode, the influence of the law of the air supply jet at the nozzle is taken into account, that is, when the air supply speed in the room decreases, the range of the air supply jet will be shortened, so when the indoor air supply volume decreases, the production equipment far away from the nozzle will be closed. The production equipment near the nozzle is turned on.
对于空调送风量与生产负荷布置协调后,对不同生产负荷下的空调系统能耗进行比较,具体实施方式为对系统能耗中的机组能耗(地源热泵能耗与空气源热泵能耗)、风机能耗、水泵能耗一一进行比较,After coordinating the air supply volume of the air conditioner with the arrangement of the production load, the energy consumption of the air conditioning system under different production loads is compared. ), fan energy consumption, and water pump energy consumption are compared one by one,
验证空调送风量与生产负荷布置协调可以节能,其中风机能耗计算方法如下:Verify that the coordination of the air supply volume of the air conditioner and the layout of the production load can save energy. The calculation method of fan energy consumption is as follows:
根据风机特性原理,风机在不同转速下的理论功率与其转速的三次方正正比。当转速从n1调节为n2时,其功率由N1变为N2,其计算公式如下:According to the principle of fan characteristics, the theoretical power of the fan at different speeds is proportional to the cube of its speed. When the speed is adjusted from n1 to n2, its power changes from N1 to N2, and its calculation formula is as follows:
N2/N1=(n2/n1)3 N2/N1=(n2/n1) 3
风机输入功率能耗计算公式为:The formula for calculating fan input power and energy consumption is:
N=PQ/(3600*1000*η)N=PQ/(3600*1000*η)
式中:N为风机轴功率,W;P为风压,Pa;Q为风量,m3/h;η为机械效率。In the formula: N is the shaft power of the fan, W; P is the wind pressure, Pa; Q is the air volume, m 3 /h; η is the mechanical efficiency.
水泵机组能耗的特征在于:水泵能耗和水泵流量及扬程相关,水泵能耗随水泵流量改变而改变。水泵输入功率的计算公式为:The characteristics of the energy consumption of the water pump unit are: the energy consumption of the water pump is related to the flow rate and head of the water pump, and the energy consumption of the water pump changes with the change of the flow rate of the water pump. The formula for calculating the input power of the pump is:
Ns=LPNs=LP
式中:L为水泵流量,m3/s;P为水泵扬程,kPa。In the formula: L is the flow rate of the pump, m 3 /s; P is the head of the pump, kPa.
比较后得到当不考虑室外气象参数变化而只考虑室内生产负荷的变化时,本发明提到的机加工厂房内采用空调系统与生产负荷布置协调进行系统节能的方法最节能。After the comparison, it is found that when the change of outdoor meteorological parameters is not considered and only the change of indoor production load is considered, the method of coordinating the air-conditioning system and production load layout in the machining workshop mentioned in the present invention is the most energy-saving method.
本发明中的机加工厂房内送风方式为单侧喷口远距离送风,生产设备是批量安排与布置的,并且每台生产设备是独立运行的,可独立完成加工件的所有加工工序。为了实现该场所的空调系统节能的目的本发明提出了一种利用空调送风量与生产负荷布置相协调节能的方法,包括根据不同生产负荷大小选择不同的送风量的过程,其中,在所述的根据不同生产负荷大小选择不同送风量的过程中包括采集冬夏生产设备不同的布置情况下生产负荷的大小的步骤,还包括根据不同的生产设备布置情况下的生产负荷大小控制送风温度选择对应大小的送风量的步骤,根据经过比较不同室内生产负荷条件下空调机组的性能、空调各设备的能耗分布情况,说明节能效果,实现了本发明节能的目的。The air supply mode in the machining workshop of the present invention is long-distance air supply from one side nozzle, the production equipment is arranged and arranged in batches, and each production equipment operates independently, and can independently complete all the processing procedures of the workpiece. In order to achieve the purpose of saving energy for the air conditioning system in this place, the present invention proposes a method for coordinating energy saving with the air supply volume of the air conditioner and the layout of the production load, including the process of selecting different air supply volumes according to different production loads. The process of selecting different air supply volumes according to different production loads mentioned above includes the steps of collecting the production loads under different layouts of production equipment in winter and summer, and also includes controlling the supply air temperature according to the production loads under different production equipment layouts The step of selecting the air supply volume corresponding to the size, according to the performance of the air-conditioning unit under different indoor production load conditions, and the energy consumption distribution of each air-conditioning equipment, illustrates the energy-saving effect, and realizes the energy-saving purpose of the present invention.
最终根据由于风机能耗在系统设备能耗中占比在10%~20%之间,在夏季风机能耗随生产负荷减小而降低,当生产负荷从100%降为25%,系统可节约能耗9%左右,冬季风机能耗随生产负荷增加而降低,当生产负荷从25%增加到100%时,系统可节约能耗11%左右,因此关于能耗方面的具体实施方式时夏季减少生产作业,冬季增加生产作业,相应的根据不同布置下的生产负荷大小选择对应大小的送风量,实现本发明的节能目的。Finally, according to the fact that the energy consumption of fans accounts for 10% to 20% of the energy consumption of system equipment, the energy consumption of fans decreases with the reduction of production load in summer. When the production load decreases from 100% to 25%, the system can save The energy consumption is about 9%, and the energy consumption of fans decreases with the increase of production load in winter. When the production load increases from 25% to 100%, the system can save energy consumption by about 11%. Therefore, the specific implementation of energy consumption is reduced in summer Production operations, increase production operations in winter, correspondingly select the corresponding air volume according to the production load under different arrangements, and realize the energy-saving purpose of the present invention.
