Obviously, the described embodiments It is a part of the embodiments of this application, not all of them.

本申请提供一种空调除尘系统，如图1和图2所示，该空调除尘系统包括：空调机构1和喷淋机构2。The present application provides an air conditioner dust removal system, as shown in FIG. 1 and FIG. 2 , the air conditioner dust removal system includes: an air conditioner mechanism 1 and a spray mechanism 2 .
其中，空调机构1适用于夏季炎热以及冬季寒冷地区，可用于制冷及制热，包括：依次首尾连接的室外换热器11、压缩机12、室内换热器13和节流装置14。室外换热器11的第一端与节流装置14的第二端连接，室外换热器11的第二端与压缩机12第一端连接，室内换热器13的第一端与压缩机12的第二端连通，室内换热器13的第二端与节流装置14的第一端连通。室内换热器13上设有回风口，回风口设有滤网。Among them, the air conditioner 1 is suitable for hot summer and cold winter regions, and can be used for cooling and heating, including: an outdoor heat exchanger 11, a compressor 12, an indoor heat exchanger 13 and a throttling device 14 connected end to end in sequence. The first end of the outdoor heat exchanger 11 is connected to the second end of the throttling device 14, the second end of the outdoor heat exchanger 11 is connected to the first end of the compressor 12, and the first end of the indoor heat exchanger 13 is connected to the compressor. 12 communicates with the second end, and the second end of the indoor heat exchanger 13 communicates with the first end of the throttling device 14 . The indoor heat exchanger 13 is provided with an air return port, and the air return port is provided with a filter screen.
如图1所示，在空调机构1进行制冷工作时，制冷剂在压缩机12中被压缩，将原本低温低压的制冷剂气体压缩成高温高压的过热蒸汽后，由压缩机12的第一端排出。此时室外换热器11作为冷凝器，室内换热器13作为蒸发器，高温高压的过热蒸汽导入冷凝器中。As shown in Figure 1, when the air conditioner 1 is performing refrigeration work, the refrigerant is compressed in the compressor 12, and after the original low-temperature and low-pressure refrigerant gas is compressed into high-temperature and high-pressure superheated steam, the first end of the compressor 12 discharge. At this time, the outdoor heat exchanger 11 serves as a condenser, and the indoor heat exchanger 13 serves as an evaporator, and high-temperature and high-pressure superheated steam is introduced into the condenser.
高温高压的过热蒸气在冷凝器中进行冷却，过热的制冷剂由气态转变为变为液态。冷却后的低温高压制冷剂经过节流装置14节流降压，将低温低压的制冷剂液体流入蒸发器。制冷剂液体在蒸发器中吸热汽化，周围气温的温度下降，冷风即被吹入室内。而制冷剂气体得以由吸回压缩机12中，再次被压缩成高温高压的过热蒸汽，维持制冷循环。The high-temperature and high-pressure superheated vapor is cooled in the condenser, and the superheated refrigerant changes from gaseous to liquid. The cooled low-temperature and high-pressure refrigerant is throttled and depressurized by the throttling device 14, and the low-temperature and low-pressure refrigerant liquid flows into the evaporator. The refrigerant liquid absorbs heat and vaporizes in the evaporator, the temperature of the surrounding air temperature drops, and the cold air is blown into the room. The refrigerant gas can be sucked back into the compressor 12 and compressed again into high-temperature and high-pressure superheated steam to maintain the refrigeration cycle.
如图2所示，空调机构1在制热时，室外换热器11作为蒸发器，室内换热器13作为冷凝器，经压缩机12压缩的高温高压过热蒸汽由压缩机12的第二端排出，送入冷凝器中，过热的蒸汽通过冷凝器散热，散出的热量由贯流风扇从风口吹出。As shown in Figure 2, when the air conditioner 1 is heating, the outdoor heat exchanger 11 acts as an evaporator, and the indoor heat exchanger 13 acts as a condenser. It is discharged and sent to the condenser. The superheated steam dissipates heat through the condenser, and the dissipated heat is blown out from the tuyere by a cross-flow fan.
过热蒸汽冷却后形成低温高压的液体后，再由节流装置14送回蒸发器中，低温低压的制冷剂在蒸发器中完成汽化的过程，制冷剂液体向外界吸收大量的热，重新变成干饱和蒸气。干饱和蒸气最后返回压缩机12，继 续第二次制热循环。After the superheated steam is cooled to form a low-temperature and high-pressure liquid, it is sent back to the evaporator by the throttling device 14. The low-temperature and low-pressure refrigerant completes the vaporization process in the evaporator, and the refrigerant liquid absorbs a large amount of heat from the outside and becomes dry saturated vapor. The dry saturated vapor is finally returned to compressor 12 to continue the second heating cycle.
喷淋机构2包括：供水管道21、第一喷淋管道、第二喷淋管道和雾化喷头22。第一喷淋管道部分位于室外换热器11中，用于在室外换热器11作为冷凝器时吸收热量。第二喷淋管道则完全位于室外换热器11外，雾化喷头22设置在回风口边沿。根据用户选择或实际需求，供水管道21可通过第一喷淋管道或第二喷淋管道与雾化喷头22连通。雾化喷头22相对回风口最好在一米范围内，以便于回流。回风口设有用于检测粉尘浓度的浮沉浓度传感器。The spray mechanism 2 includes: a water supply pipeline 21 , a first spray pipeline, a second spray pipeline and an atomizing nozzle 22 . The first spray pipe part is located in the outdoor heat exchanger 11 and is used for absorbing heat when the outdoor heat exchanger 11 is used as a condenser. The second spray pipe is located completely outside the outdoor heat exchanger 11, and the atomizing nozzle 22 is arranged on the edge of the air return port. According to the user's choice or actual needs, the water supply pipe 21 can communicate with the atomizing nozzle 22 through the first spray pipe or the second spray pipe. The atomizing nozzle 22 is preferably within one meter relative to the air return port, so as to facilitate backflow. The air return port is equipped with a floating concentration sensor for detecting dust concentration.
空调除尘系统在工作过程中，先利用浮沉浓度传感器获取当前粉尘浓度，判断粉尘浓度是否超过预设粉尘浓度。若判断获知当前粉尘浓度为超过预设粉尘浓度，则关闭或不启动喷淋机构2。若判断获知当前粉尘浓度超过预设粉尘浓度，则启动喷淋机构2并获取空调机构1当前的运行模式。根据空调当前的运行模式控制空调机构1和喷淋机构2。During the working process of the air-conditioning dust removal system, the current dust concentration is obtained by using the floating concentration sensor to judge whether the dust concentration exceeds the preset dust concentration. If it is judged that the current dust concentration exceeds the preset dust concentration, the spray mechanism 2 is closed or not activated. If it is determined that the current dust concentration exceeds the preset dust concentration, the spray mechanism 2 is started and the current operating mode of the air conditioning mechanism 1 is obtained. The air conditioner 1 and the spray mechanism 2 are controlled according to the current operating mode of the air conditioner.
若判断获知空调机构当前以制冷模式运行，则控制供水管道21通过第一喷淋管道与雾化喷头22连通，利用供水管道21中的水流吸收室外换热器11中的热量，再通过雾化喷头22将蒸汽喷入室内空气中，雾化喷淋形成的水蒸气小颗粒，其对灰尘有聚集作用，聚集后利用回风口回风，通过室内换热器13液化，液化后的水流将夹杂的灰尘带走，可避免飞絮、灰尘堆积，起到净化空气的作用。If it is judged that the air-conditioning mechanism is currently operating in cooling mode, the water supply pipeline 21 is controlled to communicate with the atomizing nozzle 22 through the first spray pipeline, and the water flow in the water supply pipeline 21 is used to absorb the heat in the outdoor heat exchanger 11, and then through the atomization The nozzle 22 sprays steam into the indoor air, and the small water vapor particles formed by atomization and spraying have the effect of gathering dust. After gathering, the return air is used to return air, and the indoor heat exchanger 13 is liquefied. The liquefied water flow will be mixed Take away the dust, which can avoid the accumulation of flying catkins and dust, and play the role of purifying the air.
若判断获知空调机构当前以制热模式运行，则控制供水管道21通过第二喷淋管道与雾化喷头22连通，供水管道21中的水流直接流入雾化喷头22，对室内空气进行净化。If it is determined that the air conditioner is currently operating in the heating mode, the water supply pipe 21 is controlled to communicate with the atomizing nozzle 22 through the second spray pipe, and the water in the water supply pipe 21 directly flows into the atomizing nozzle 22 to purify the indoor air.
一般要求生活工作空间内粉尘浓度低于4mg/m 3，因此当浮沉浓度传感器检测到空间内粉尘浓度高于4mg/m 3时，遥控器直接接收信号，报警灯闪烁，此时用户可以选择暂时进入另一个空间内工作生活，在超标空间内开启空调除尘功能。空调接收信号后，判定刚才空调进行的制热还是制冷模式，从而控制第一喷淋管道或第二喷淋管道开启或者关闭，直到再次检测空间内粉尘浓度达标，停止工作，发出信号反馈到遥控器上。 It is generally required that the dust concentration in the living and working space is lower than 4mg/m 3 , so when the floating concentration sensor detects that the dust concentration in the space is higher than 4mg/m 3 , the remote controller receives the signal directly, and the alarm light flashes. At this time, the user can choose to temporarily Enter another space to work and live, and turn on the air-conditioning and dust removal function in the over-standard space. After the air conditioner receives the signal, it determines whether the air conditioner is in the heating or cooling mode just now, so as to control the opening or closing of the first spray pipe or the second spray pipe, until the dust concentration in the space is detected again, stop working, and send a signal to feed back to the remote control device.

空调除尘系统在工作过程中，先利用浮沉浓度传感器获取当前粉尘浓度，判断粉尘浓度是否超过预设粉尘浓度。若判断获知当前粉尘浓度为超过预设粉尘浓度，则关闭或不启动喷淋机构2。若判断获知当前粉尘浓度超过预设粉尘浓度，则启动喷淋机构2并获取空调机构1当前的运行模式。根据空调当前的运行模式控制空调机构1和喷淋机构2。During the working process of the air-conditioning dust removal system, the current dust concentration is obtained by using the floating concentration sensor to judge whether the dust concentration exceeds the preset dust concentration. If it is judged that the current dust concentration exceeds the preset dust concentration, the spray mechanism 2 is closed or not activated. If it is determined that the current dust concentration exceeds the preset dust concentration, the spray mechanism 2 is started and the current operating mode of the air conditioning mechanism 1 is obtained. The air conditioner 1 and the spray mechanism 2 are controlled according to the current operating mode of the air conditioner.
若判断获知空调机构当前以制冷模式运行，则控制供水管道21通过第一喷淋管道与雾化喷头22连通，利用供水管道21中的水流吸收室外换热器11中的热量，再通过雾化喷头22将蒸汽喷入室内空气中，雾化喷淋形成的水蒸气小颗粒，其对灰尘有聚集作用，聚集后利用回风口回风，通过室内换热器13液化，液化后的水流将夹杂的灰尘带走，可避免飞絮、灰尘堆积，起到净化空气的作用。If it is judged that the air-conditioning mechanism is currently operating in cooling mode, the water supply pipeline 21 is controlled to communicate with the atomizing nozzle 22 through the first spray pipeline, and the water flow in the water supply pipeline 21 is used to absorb the heat in the outdoor heat exchanger 11, and then through the atomization The nozzle 22 sprays steam into the indoor air, and the small water vapor particles formed by atomization and spraying have the effect of gathering dust. After gathering, the return air is used to return air, and the indoor heat exchanger 13 is liquefied. The liquefied water flow will be mixed Take away the dust, which can avoid the accumulation of flying catkins and dust, and play the role of purifying the air.
若判断获知空调机构当前以制热模式运行，则控制供水管道21通过第二喷淋管道与雾化喷头22连通，供水管道21中的水流直接流入雾化喷头22，对室内空气进行净化。If it is determined that the air conditioner is currently operating in the heating mode, the water supply pipe 21 is controlled to communicate with the atomizing nozzle 22 through the second spray pipe, and the water in the water supply pipe 21 directly flows into the atomizing nozzle 22 to purify the indoor air.
一般要求生活工作空间内粉尘浓度低于4mg/m 3，因此当浮沉浓度传感器检测到空间内粉尘浓度高于4mg/m 3时，遥控器直接接收信号，报警灯闪烁，此时用户可以选择暂时进入另一个空间内工作生活，在超标空间内开启空调除尘功能。空调接收信号后，判定刚才空调进行的制热还是制冷模式，从而控制第一喷淋管道或第二喷淋管道开启或者关闭，直到再次检测空间内粉尘浓度达标，停止工作，发出信号反馈到遥控器上。 It is generally required that the dust concentration in the living and working space is lower than 4mg/m 3 , so when the floating concentration sensor detects that the dust concentration in the space is higher than 4mg/m 3 , the remote controller receives the signal directly, and the alarm light flashes. At this time, the user can choose to temporarily Enter another space to work and live, and turn on the air-conditioning and dust removal function in the over-standard space. After the air conditioner receives the signal, it determines whether the air conditioner is in the heating or cooling mode just now, so as to control the opening or closing of the first spray pipe or the second spray pipe, until the dust concentration in the space is detected again, stop working, and send a signal to feed back to the remote control device.
当室内空气中混入自来水产生的水蒸气时，蒸汽极易与空气中漂浮的灰尘聚集，从而形成类似雾霾的效果，因此除尘功能需要发生在室内无人的环境中。蒸汽与浮沉聚集后，通过回风口引风，将灰尘水雾重新吸回空调，然后空调室内机将水雾冷凝，形成冷凝水后排到室外。此时需要注意在冬季或温度较低的状态，避免水流在室外换热器11冷凝结霜，因此在 实际控制过程中还包括：When the indoor air is mixed with water vapor generated by tap water, the steam will easily gather with the dust floating in the air, thus forming an effect similar to smog. Therefore, the dust removal function needs to be performed in an indoor environment where no one is present. After the steam and ups and downs are gathered, the wind is drawn through the air return port, and the dust and water mist are sucked back to the air conditioner, and then the indoor unit of the air conditioner condenses the water mist to form condensed water and then discharge it outdoors. At this time, it is necessary to pay attention to avoid condensation and frosting of the water flow in the outdoor heat exchanger 11 in winter or in a low temperature state, so the actual control process also includes:
获取室内温度、室外温度和设定温度，将室内温度、室外温度和设定温度进行对比。Get the indoor temperature, outdoor temperature and set temperature, and compare the indoor temperature, outdoor temperature and set temperature.
若判断获知室外温度＞结霜温度，此时空调除尘系统不存在结霜的风险，则控制空调机构1运行制冷模式，并控制供水管道21通过第一喷淋管道与雾化喷头22连通。If it is judged that the outdoor temperature is greater than the frosting temperature, and there is no risk of frosting in the air-conditioning dust removal system, the air-conditioning mechanism 1 is controlled to operate in cooling mode, and the water supply pipe 21 is controlled to communicate with the atomizing nozzle 22 through the first spray pipe.
如果此时判断获知室外温度＞结霜温度且室内温度＞设定温度，则控制空调机构正常运行制冷模式，制供水管道21通过第一喷淋管道与雾化喷头22连通。如果此时判断获知室外温度＞结霜温度且室内温度≤设定温度，则控制空调机构以低频运行制冷模式，低频运行压缩机12，制供水管道21通过第一喷淋管道与雾化喷头22连通。If it is judged at this time that the outdoor temperature>the frosting temperature and the indoor temperature>the set temperature, the air conditioner is controlled to operate normally in the cooling mode, and the water supply pipe 21 is communicated with the atomizing nozzle 22 through the first spray pipe. If it is judged at this time that the outdoor temperature>the frosting temperature and the indoor temperature≤the set temperature, then control the air conditioner to operate the cooling mode at a low frequency, operate the compressor 12 at a low frequency, and control the water supply pipeline 21 to pass through the first spray pipeline and the atomizing nozzle 22 connected.
