技术领域technical field
本发明属于变风量空调系统领域，具体涉及变风量空调末端的节能控制，特别是一种基于气候补偿的变风量空调末端温度控制系统及方法。The invention belongs to the field of variable air volume air conditioning systems, and in particular relates to the energy-saving control of the terminal of the variable air volume air conditioner, in particular to a temperature control system and method for the terminal of the variable air volume air conditioner based on climate compensation.
背景技术Background technique
变风量空调系统因系统的室内空气品质良好、部分负荷时节能性优越以及区域控制灵活，广泛应用于各类办公、商业建筑中，但其又是现代楼宇的能耗大户。其通常是根据最大计算负荷来设计，采用固定送风温度而改变送风量的方式来满足用户需求，不能随室外温度的变化改变送风温度设定值。新风量的大小影响室内空气质量，影响系统负荷的大小，同时也影响系统能耗的大小。新风以稀释室内污染物浓度，使之达到用户可接受的浓度为标准。区域新风需求量与用户人数成正比，与送风量成正比。实际中，室外气候时刻在变化，直接影响新风负荷的大小。若不能根据室外温度的变化及时改变送风温度设定值来补偿送风温度，会造成室内过冷或过热现象，不能有效满足用户在多种气候条件下的用冷/热需求。由此可见，研究一种变风量空调的节能方案势在必行。Variable air volume air-conditioning system is widely used in various office and commercial buildings because of its good indoor air quality, superior energy saving performance at partial load, and flexible area control. It is usually designed according to the maximum calculation load, and the air supply temperature setting value cannot be changed with the change of the outdoor temperature to meet the user's needs by fixing the air supply temperature and changing the air supply volume. The size of the fresh air volume affects the indoor air quality, affects the size of the system load, and also affects the size of the system energy consumption. The fresh air is based on diluting the concentration of indoor pollutants to make it reach the concentration acceptable to users. The demand for fresh air in the area is directly proportional to the number of users and the air supply volume. In practice, the outdoor climate is changing all the time, which directly affects the size of the fresh air load. If the set value of the supply air temperature cannot be changed in time to compensate the supply air temperature according to the change of the outdoor temperature, it will cause indoor overcooling or overheating, and cannot effectively meet the cooling/heating needs of users under various climatic conditions. It can be seen that it is imperative to study an energy-saving scheme for variable air volume air conditioners.
目前，中央空调系统的气候补偿节能控制技术主要有两类：At present, there are two main types of climate compensation and energy-saving control technologies for central air-conditioning systems:
第一类：通过调整冷水机组的运行参数，使中央空调系统根据外部气候变化调节冷水机组冷冻水供水温度实现节能；具体是气候补偿控制器通过采集室内温度、室外温湿度、冷机运行状态参数，通过自寻优的算法寻找冷机的最佳工作点，并计算水系统各设备的最佳工作频率，控制使之在最佳工作频率下运行，从而调整冷冻水供水温度，实现节能。例如：申请号为200810118088.1，名称为“中央空调气候补偿控制器和中央空调气候补偿方法”的中国专利申请。该申请中的方法虽然在一定程度上实现了水系统的节能，但没有考虑室外气候变化对风系统的影响。The first category: by adjusting the operating parameters of the chiller, the central air-conditioning system can adjust the chilled water supply temperature of the chiller according to external climate changes to achieve energy saving; specifically, the climate compensation controller collects indoor temperature, outdoor temperature and humidity, and chiller operating status parameters , through the self-optimization algorithm to find the best working point of the chiller, and calculate the best working frequency of each equipment in the water system, and control it to run at the best working frequency, so as to adjust the chilled water supply temperature and realize energy saving. For example: a Chinese patent application with application number 200810118088.1 titled "Central Air Conditioning Climate Compensation Controller and Central Air Conditioning Climate Compensation Method". Although the method in this application realizes the energy saving of the water system to a certain extent, it does not consider the impact of outdoor climate change on the wind system.
第二类：通过在系统供水管路上设置调节阀、调节阀通过执行器控制、执行器通过恒温控制器进行调节、恒温控制器上设置热信号端子，恒温控制器通过控制执行器的开度实现进水流量的调整从而控制供回水温差。例如：申请号为200910157033.6，名称为集成气候补偿的暖通回水温度控制节能方法的专利申请。该方法同样是只考虑了外部气候变化对水系统的影响，未考虑对风系统的影响。The second type: by setting a regulating valve on the water supply pipeline of the system, the regulating valve is controlled by the actuator, the actuator is adjusted by the thermostat controller, the thermal signal terminal is set on the thermostat controller, and the thermostat controller controls the opening of the actuator. The adjustment of the inlet water flow can control the temperature difference between the supply and return water. For example: the application number is 200910157033.6, and the title is a patent application for an energy-saving method for HVAC return water temperature control with integrated climate compensation. This method also only considers the impact of external climate change on the water system, and does not consider the impact on the wind system.

本发明的有益效果如下：The beneficial effects of the present invention are as follows:
1、本发明的气候补偿调节介质为风，新风温度即为室外温度，新风量的大小直接影响系统负荷的大小，也就影响系统总能耗的大小，所以新风量对整个过程的影响非常大，同时新风量对室内环境品质有直接的影响。本发明中，上位机通过对当前新风量的大小、室外温度的连续监测及用户对室内温度的需求来确定当前最佳送风温度设定值，进而通过送风温度控制器控制水阀的开度，调节水流量，实现变风量空调系统中送风温度与室外温度变化的自动气候补偿，达到送风温度随用户需冷/热量的变化而变化，实现按需供冷/热的目标，在保证供冷/热品质的同时实现节能。1. The climate compensation regulating medium of the present invention is wind, and the temperature of the fresh air is the outdoor temperature. The size of the fresh air volume directly affects the size of the system load, which also affects the size of the total energy consumption of the system, so the fresh air volume has a great influence on the whole process , while the fresh air volume has a direct impact on the quality of the indoor environment. In the present invention, the upper computer determines the current optimal air supply temperature setting value through the continuous monitoring of the current fresh air volume, outdoor temperature and the user's demand for indoor temperature, and then controls the opening of the water valve through the air supply temperature controller. temperature, adjust the water flow, realize the automatic climate compensation of the change of the supply air temperature and the outdoor temperature in the variable air volume air conditioning system, achieve the change of the supply air temperature with the change of cooling/heating required by the user, and realize the goal of cooling/heating on demand. Realize energy saving while ensuring cooling/heating quality.
2、已有的气候补偿方法是通过构筑建筑物冷消耗曲线与用户的设定温度，计算用户的需冷量，然后与冷水机组的工作效率曲线计算出冷机的有效工作点。在这过程中只处理了室外温度对水系统的影响，而未考虑室外温度对风系统的影响，及新风量对风系统的影响。本发明根据新风量变化、室内用户的需求、室外温度变化以及与系统总能耗间的关系，利用总能耗最小原则，确定出不同新风量下最佳的送风温度，本发明可用于楼宇自控的变风量空调系统末端控制装置中。2. The existing climate compensation method is to calculate the cooling capacity required by the user by constructing the cooling consumption curve of the building and the user's set temperature, and then calculate the effective working point of the chiller with the working efficiency curve of the chiller. In this process, only the influence of outdoor temperature on the water system is dealt with, but the influence of outdoor temperature on the wind system and the influence of fresh air volume on the wind system are not considered. According to the relationship between the change of fresh air volume, the needs of indoor users, the change of outdoor temperature and the total energy consumption of the system, the present invention uses the principle of minimum total energy consumption to determine the optimal air supply temperature under different fresh air volumes. The present invention can be used in buildings In the terminal control device of the automatic variable air volume air conditioning system.
3、传统的供暖系统中的气候补偿器的调节量为供水温度，介质是水。空调系统中的气候补偿器着重在于调节冷水机组的工作参数，而改变冷冻水供水温度，从而节约冷水机组的能耗，介质同样是水；而本发明的系统中，气候补偿调节量为送风温度，通过调节冷冻水阀使之达到最优值，介质为风。3. The adjustment value of the climate compensator in the traditional heating system is the water supply temperature, and the medium is water. The climate compensator in the air conditioning system focuses on adjusting the working parameters of the chiller to change the chilled water supply temperature, thereby saving the energy consumption of the chiller, and the medium is also water; and in the system of the present invention, the climate compensation adjustment amount is the air supply The temperature is adjusted to the optimum value by adjusting the chilled water valve, and the medium is wind.

实施例Example
以下是本发明的方法的一个实施例，给出该实施例的目的是为了更清楚地说明本发明的具体实施方式，本发明所要保护的范围不限于该实施例。The following is an example of the method of the present invention. The purpose of giving this example is to illustrate the specific implementation of the present invention more clearly, and the protection scope of the present invention is not limited to this example.
步骤11中设定新风量为最小新风量(即设定新风阀开度为10％)，步骤12中采集当前室外温度，步骤13中给定室内温度设定值为19℃，室内温度通过末端控制回路控制，如图5；步骤14中，送风温度设定值在26-29℃范围内变化，送风温度通过送风温度控制回路控制，如图6。图6中，温度控制器和风量控制器集成在一块组成末端控制器。系统闭环稳定运行之后，得到具体室外温度值下(室外温度为0℃)送风温度设定值与系统总能耗关系曲线如图7。图7中，随送风温度设定值的增加，系统的总耗能最小值点所对应的送风温度设定值即为该工况下的最优送风温度设定值。本实验系统中，最优送风温度设定值系统总能耗比最高点节能35.5％。室外温度范围为-1～3℃，室内设定值为19℃时，按照步骤17得到如图8所示的拟合曲线：y＝1.3923x1+0.5594x2，其中，x1为室内温度设定值，x2为室外温度，y为最优送风温度设定值。In step 11, the fresh air volume is set to the minimum fresh air volume (that is, the opening of the fresh air valve is set to 10%). In step 12, the current outdoor temperature is collected. In step 13, the set value of the indoor temperature is 19°C. The control loop is controlled, as shown in Figure 5; in step 14, the set value of the air supply temperature is changed within the range of 26-29°C, and the air supply temperature is controlled by the air supply temperature control loop, as shown in Figure 6. In Figure 6, the temperature controller and air volume controller are integrated together to form the terminal controller. After the closed-loop stable operation of the system, the relationship curve between the set value of the supply air temperature and the total energy consumption of the system at a specific outdoor temperature value (outdoor temperature is 0°C) is obtained as shown in Figure 7. In Figure 7, with the increase of the set value of the air supply temperature, the set value of the air supply temperature corresponding to the minimum point of the total energy consumption of the system is the optimal set value of the air supply temperature under this working condition. In this experimental system, the total energy consumption of the system at the optimal air supply temperature setting value is 35.5% less than that at the highest point. When the outdoor temperature range is -1 to 3°C and the indoor set value is 19°C, follow step 17 to obtain the fitting curve shown in Figure 8: y=1.3923x 1 +0.5594x 2 , where x 1 is the indoor temperature The set value, x 2 is the outdoor temperature, and y is the set value of the optimal air supply temperature.
上述室内温度设定值由末端房间控制面板设定，本发明所采用的实验系统末端为压力无关型，室内温度由末端控制回路双闭环控制，控制回路如图5，主环为温度控制回路，副环是风量控制回路。温度控制器的输入为室内温度设定值与由室内温度传感器检测到的室内实际温度的差值，输出为风量设定值；风量控制器的输入为温度控制器的输出与由风量传感器检测到的房间实际送风量的差值，输出为末端风阀的开度，通过调节末端风阀的输出风量(即送入房间的风量)，实现末端房间温度的调节。The above-mentioned indoor temperature setting value is set by the control panel of the end room. The end of the experimental system adopted in the present invention is a pressure-independent type. The indoor temperature is controlled by the double closed-loop of the end control loop. The control loop is shown in Figure 5. The main loop is a temperature control loop. The secondary loop is the air volume control loop. The input of the temperature controller is the difference between the indoor temperature setting value and the actual indoor temperature detected by the indoor temperature sensor, and the output is the air volume setting value; the input of the air volume controller is the output of the temperature controller and the temperature detected by the air volume sensor. The difference between the actual air supply volume of the room, the output is the opening of the end damper, and the adjustment of the end room temperature is realized by adjusting the output air volume of the end damper (that is, the air volume sent into the room).
上述送风温度由送风温度控制回路控制，如图6所示，其控制原理是以送风温度设定值与送风温度传感器测量到的实际送风温度的差值作为送风温度控制器的输入，通过调节系统中冷冻水阀的开度改变换热器的水流量实现对送风温度的控制。The above air supply temperature is controlled by the air supply temperature control loop, as shown in Figure 6, the control principle is to use the difference between the set value of the supply air temperature and the actual supply air temperature measured by the supply air temperature sensor as the supply air temperature controller By adjusting the opening of the chilled water valve in the system and changing the water flow of the heat exchanger, the temperature of the air supply can be controlled.
综合不同时间段对室内温度的不同要求，在气候补偿曲线数据库内预设定不同新风量下，室外温度、室内温度设定值、最优送风温度设定值曲线，使控制系统送风温度设定值在不同末端用户条件下随室外温度变化。从而满足不同室外温度、不同时间段室温的要求，做到分时制热、按需制热，达到舒适、节能的目的。Integrating the different requirements for indoor temperature in different time periods, the curves of outdoor temperature, indoor temperature setting value, and optimal air supply temperature setting value are preset in the climate compensation curve database under different fresh air volumes, so that the control system air supply temperature The set point varies with outdoor temperature under different end-user conditions. In order to meet the requirements of different outdoor temperatures and room temperature in different time periods, time-sharing heating and on-demand heating can be achieved to achieve the purpose of comfort and energy saving.
中央空调制冷/制热期间，因各种条件的变化，气候的变化不是很有规律，上位机根据当前新风量确定对应曲线，室外温度传感器实时采集室外温度，将此温度信号传输至上位机，上位机根据室外温度及用户的室内温度设定值，在气候补偿数据库中寻找此时的送风温度设定值；送风温度控制器根据其送风温度设定值与实际送风温度的偏差来调节冷冻水阀开度，改变换热器的水流量，实现对送风温度的控制，以补偿室外温度变化的影响，获得最佳舒适度和最小能源消耗。During the cooling/heating period of the central air conditioner, due to changes in various conditions, the climate change is not very regular. The upper computer determines the corresponding curve according to the current fresh air volume, and the outdoor temperature sensor collects the outdoor temperature in real time, and transmits the temperature signal to the upper computer. According to the outdoor temperature and the user's indoor temperature setting value, the upper computer searches for the set value of the supply air temperature in the climate compensation database; the supply air temperature controller is based on the deviation between the set value of the supply air temperature and the actual To adjust the opening of the chilled water valve, change the water flow of the heat exchanger, and realize the control of the air supply temperature, so as to compensate the influence of the outdoor temperature change and obtain the best comfort and minimum energy consumption.
本发明的气候补偿方法采用实际工程中系统测试时数据库中的信息进行统计分析，随系统运行时间累加可逐渐丰富数据库。The climate compensation method of the present invention uses the information in the database during the system test in the actual project for statistical analysis, and the database can be gradually enriched with the accumulation of system running time.
