近几年，随着我国经济的发展、城市人口的过快增长以及城市化进程的加快，出现的雾霾等空气污染问题已成为人们广泛关注的焦点。据报道，2015年11月辽宁沈阳自8日凌晨3点开始到9日凌晨1点，空气质量连续22小时“爆表”，峰值曾超过1000微克／立方米。针对雾霾等空气污染问题，亟需提出防霾空调系统改造项目。In recent years, with the development of my country's economy, the rapid growth of urban population and the acceleration of urbanization, air pollution problems such as smog have become the focus of widespread attention. According to reports, in November 2015, from 3:00 a.m. on the 8th to 1:00 a.m. on the 9th, the air quality in Shenyang, Liaoning Province was “off the charts” for 22 consecutive hours, with a peak value exceeding 1,000 micrograms per cubic meter. In view of air pollution problems such as smog, there is an urgent need to propose anti-smog air conditioning system renovation projects.
传统的集中式空调系统大多是室内机组通过布置在天花板上回风口将空气吸入，与从室外引进的新风相互混合，经过热湿处理后通过送风口向室内各个房间输送空气。当今既有公共建筑和部分工业建筑绝大多数安装的是集中式空调系统，该系统为混合式空调系统，主要有一次回风和二次回风方式，需要引入部分室外新风与室内回风混合，再经过热湿处理器送入室内，以达到节能又保证洁净度的目的。但是在雾霾、沙尘暴等室外空气恶劣的情况下，该系统运行不仅不能保证室内清洁舒适，相反会引入大量污染物，导致室内空气质量下降。Most of the traditional centralized air-conditioning systems are indoor units that inhale the air through the return air outlet arranged on the ceiling, mix it with the fresh air introduced from the outside, and deliver the air to each room through the air outlet after heat and humidity treatment. Today, the vast majority of existing public buildings and some industrial buildings are equipped with centralized air conditioning systems. This system is a hybrid air conditioning system. It mainly has primary return air and secondary return air. It needs to introduce part of the outdoor fresh air to mix with the indoor return air. It is sent indoors through a heat and humidity processor to achieve the purpose of saving energy and ensuring cleanliness. However, in the case of bad outdoor air such as smog and sandstorms, the operation of the system not only cannot ensure indoor cleanliness and comfort, but will introduce a large amount of pollutants, resulting in a decline in indoor air quality.

本发明涉及一种新风与回风协作送风的防霾空调系统，如图1所示，包括空调装置和自控装置，空调装置包括：新风阀4、回风阀6、排风阀2、百叶片轮水洗净化器8和静电过滤器9；自控装置即空调风机联动控制装置，自控装置包括排风管道1、新风管道3和回风管道5，排风管道1和新风管道3均连通房间11，新风管道3进入房间11后连接空调室内机10，空调室内机10连接送风管道7，回风管道5连接空调室内机10；在房间11内部空调室内机10前段的新风管道3上设有新风阀4，在房间11外部的排风管道1上设有排风阀2，在回风管道5上设有回风阀6。这样设置能够保证该系统的正常运行，并且该系统在原有的系统基础上设置电动阀门并联动控制对机房处进行局部改造，达到防霾、净化室外空气的目的。The present invention relates to an anti-smog air-conditioning system in which fresh air and return air cooperate to supply air. As shown in FIG. 1 , it includes an air conditioner and an automatic control device. The blade wheel water washing purifier 8 and the electrostatic filter 9; the automatic control device is the linkage control device of the air conditioner fan, the automatic control device includes the exhaust duct 1, the fresh air duct 3 and the return air duct 5, and the exhaust duct 1 and the fresh air duct 3 are connected to the room 11 , the fresh air duct 3 enters the room 11 and is connected to the air-conditioning indoor unit 10, the air-conditioning indoor unit 10 is connected to the air supply duct 7, and the return air duct 5 is connected to the air-conditioning indoor unit 10; The fresh air valve 4 is provided with an exhaust valve 2 on the exhaust duct 1 outside the room 11, and a return valve 6 is provided on the return duct 5. This setting can ensure the normal operation of the system, and the system sets up electric valves on the basis of the original system and performs linkage control to partially renovate the machine room to achieve the purpose of preventing haze and purifying the outdoor air.
如图3所示，在新风管道3的室外部分设有PM2.5浓度传感器17，在送风管道7的末端设有二氧化碳浓度传感器16。设置PM2.5浓度传感器17的目的在于，检测室外PM2.5的浓度，当室外PM2.5浓度传感器检测到室外PM2.5浓度超过0.075mg/m³时，即室外空气质量不达标时，传感器将这一信号传递给新风阀、排风阀和回风阀，通过控制新风阀、排风阀的开闭和回风阀的开度，使系统临时封闭式运行。设置二氧化碳浓度传感器16的目的在于，检测室内二氧化碳浓度，传感器将这一信号传递给各个阀门、水洗净化器和静电过滤器，通过控制阀门的启停和开度、净化装置的开闭，从而调节该系统的运行状态。As shown in FIG. 3 , a PM2.5 concentration sensor 17 is provided at the outdoor part of the fresh air duct 3 , and a carbon dioxide concentration sensor 16 is provided at the end of the air supply duct 7 . The purpose of setting the PM2.5 concentration sensor 17 is to detect the concentration of outdoor PM2.5. When the outdoor PM2.5 concentration sensor detects that the outdoor PM2.5 concentration exceeds 0.075mg/m³, that is, when the outdoor air quality is not up to standard, the sensor will This signal is transmitted to the fresh air valve, exhaust valve and return air valve. By controlling the opening and closing of the fresh air valve, exhaust valve and return air valve, the system is temporarily closed. The purpose of setting up the carbon dioxide concentration sensor 16 is to detect the indoor carbon dioxide concentration, and the sensor transmits this signal to each valve, washing purifier and electrostatic filter, by controlling the start and stop of the valve and the opening and closing of the purification device, thereby adjusting The operating state of the system.
在新风阀4与空调室内机10之间新风管道的风管上，还可以根据用户需求增设有百叶片轮水洗净化器8。百叶片轮水洗净化器8能够净化从室外引入的污浊空气，保证新风有足够的洁净度。On the air duct of the fresh air pipeline between the fresh air valve 4 and the air-conditioning indoor unit 10, a louver wheel water washing purifier 8 can also be added according to user needs. The louver wheel washing purifier 8 can purify the dirty air introduced from the outside to ensure that the fresh air has sufficient cleanliness.
如图2所示，所述百叶片轮水洗净化器8包括风管12和安装在风管12下方的净化水槽14，水槽14中装满水，在风管12和水槽14的中间布置有风扇叶片13，风扇叶片13的为活性炭材质的叶片，水槽14可拆卸。这样设置的工作原理是，当室外空气被引入室内，通过百叶片轮水洗净化器8的时候，可以经过活性炭材质的叶片达到净化空气的目的，而且叶片在引入新风的动力下会发生旋转，当吸附有污染物的叶片旋转到下方水槽中时，叶片会被水槽中的水冲刷清洗，如此循环已达到净化新风的目的。水槽可拆卸主要是可以定期换水，保证水的清洁度。As shown in Figure 2, the louver wheel water washing purifier 8 includes an air duct 12 and a purified water tank 14 installed below the air duct 12, the water tank 14 is filled with water, and a fan is arranged in the middle of the air duct 12 and the water tank 14 Blade 13, fan blade 13 is the blade of activated carbon material, and water tank 14 is detachable. The working principle of this setting is that when the outdoor air is introduced into the room and passes through the louver wheel to wash the purifier 8, it can pass through the blades made of activated carbon to achieve the purpose of purifying the air, and the blades will rotate under the power of introducing fresh air. When the blades adsorbed with pollutants rotate into the water tank below, the blades will be washed and cleaned by the water in the water tank, and this cycle has achieved the purpose of purifying the fresh air. The sink is detachable mainly to change the water regularly to ensure the cleanliness of the water.
根据用户需求还可以在所述送风管道7的末端还设置有静电过滤器9。设置静电过滤器9的作用是，当室外空气污染较严重，百叶片轮水洗净化器8不能很好地解决问题时，静电过滤器9就是一个二级过滤装置，再对经过空调室内机处理过的空气进行二次过滤，更好的达到净化室外空气的目的，再将过滤后的空气经过送风管道7送入室内。An electrostatic filter 9 may also be provided at the end of the air supply duct 7 according to user requirements. The effect of setting the electrostatic filter 9 is that when the outdoor air pollution is serious and the louver wheel washing purifier 8 cannot solve the problem well, the electrostatic filter 9 is a secondary filter device, and then the air-conditioning indoor unit has been treated The air is filtered twice to better achieve the purpose of purifying the outdoor air, and then the filtered air is sent into the room through the air supply duct 7.

将新风管道、排风管道与回风管道分别增设阀门，关闭新风与排风管道阀门，调节回风管道阀门来加大回风量，保证总送风量不变，形成室内空气内部循环的临时封闭式系统。同时，可以根据客户需求加装百叶片轮或静电过滤器等来改善室内空气质量。Add valves to the fresh air duct, exhaust duct and return air duct respectively, close the valves of the fresh air duct and exhaust duct, adjust the valve of the return air duct to increase the return air volume, ensure that the total air supply volume remains unchanged, and form a temporary closure of the internal circulation of indoor air formula system. At the same time, louvers or electrostatic filters can be added according to customer needs to improve indoor air quality.
实施例1Example 1
将新风管道、排风管道与回风管道分别增设阀门，关闭新风与排风管道阀门，调节回风管道阀门来加大回风量，保证总送风量不变，形成室内空气内部循环的临时封闭式系统。在雾霾、沙尘暴等室外空气恶劣的情况下，本发明通过设置电动阀门并联动控制对空调系统进行局部改造，将混合式空调系统转换为临时封闭式系统，实现室内与室外污浊空气的暂时隔离。在室外污染指数降低时，再通过新风阀、排风阀、回风阀和空调风机联动控制转换为混合式空调系统。Add valves to the fresh air duct, exhaust duct and return air duct respectively, close the valves of the fresh air duct and exhaust duct, adjust the valve of the return air duct to increase the return air volume, ensure that the total air supply volume remains unchanged, and form a temporary closure of the internal circulation of indoor air formula system. In the case of bad outdoor air such as smog and sandstorms, the invention partially transforms the air conditioning system by setting electric valves and linkage control, and converts the hybrid air conditioning system into a temporary closed system to realize the temporary isolation of indoor and outdoor dirty air . When the outdoor pollution index decreases, it will be converted to a hybrid air conditioning system through the linkage control of the fresh air valve, exhaust valve, return air valve and air conditioning fan.
本发明涉及两种情况：通过空调风机联动控制装置控制，当室外空气遇到雾霾、沙尘暴等恶劣天气时，新风阀与排风阀关闭，这就使得室外带有大量污染物的气体不会流入室内，保证了室内空气的洁净度与人员的舒适度，同时还减少了对空调末端装置的损坏，回风阀开大加大回风量，保证室内的总送风量不变；当室外空气污染指数降低时，新风阀与排风阀打开，回风阀关小减小室内回风量，增大新风量，从而保证室内总的送风量不变。The present invention involves two situations: through the control of the linkage control device of the air conditioner fan, when the outdoor air encounters severe weather such as smog and sandstorms, the fresh air valve and the exhaust valve are closed, so that the outdoor gas with a large amount of pollutants will not It flows into the room, which ensures the cleanliness of the indoor air and the comfort of the personnel, and at the same time reduces the damage to the terminal device of the air conditioner. When the pollution index decreases, the fresh air valve and exhaust valve are opened, the return air valve is closed to reduce the indoor return air volume, and increase the fresh air volume, so as to ensure that the total indoor air supply volume remains unchanged.

本发明所制备的空调风机联动装置，其运行状况如下：当室外PM2.5浓度传感器检测到室外PM2.5浓度超过0.075mg/m³时，即室外空气质量不达标时，关闭新风阀、排风阀，开大回风阀，系统临时封闭式运行。运行一段时间后，当室内的二氧化碳浓度传感器检测到室内二氧化碳浓度大于0.1%时，强制打开新风阀，排风阀，关小回风阀，在一次回风系统运行模式下新风阀的开度按最小新风比计算，排风阀的开度按室内空气压强达到5-10Pa计算，然后打开风机和表冷器水阀18，紧接着打开水轮净化器和静电过滤器，从而保证新风的品质。系统运行一段时间后，当室内二氧化碳浓度下降到0.1%以下时，关闭水轮净化器和静电过滤器，然后关闭新风阀和排风阀，将回风阀开到最大，系统又转换为临时封闭系统，如此循环来保证室内空气品质和人员舒适度。The air-conditioning fan linkage device prepared by the present invention has the following operating conditions: when the outdoor PM2.5 concentration sensor detects that the outdoor PM2.5 concentration exceeds 0.075mg/m3, that is, when the outdoor air quality is not up to standard, close the fresh air valve and exhaust air. Valve, open the large return air valve, the system temporarily closed operation. After running for a period of time, when the indoor carbon dioxide concentration sensor detects that the indoor carbon dioxide concentration is greater than 0.1%, it will force open the fresh air valve, the exhaust valve, and close the return air valve. Calculate the minimum fresh air ratio, the opening of the exhaust valve is calculated based on the indoor air pressure reaching 5-10Pa, then open the fan and the water valve 18 of the surface cooler, and then open the water wheel purifier and electrostatic filter, so as to ensure the quality of fresh air. After the system has been running for a period of time, when the indoor carbon dioxide concentration drops below 0.1%, close the water wheel purifier and electrostatic filter, then close the fresh air valve and exhaust valve, open the return air valve to the maximum, and the system will switch to temporary closed system, thus circulating to ensure indoor air quality and occupant comfort.
