请参看图1，图1为本申请实施例提供的一种新风装置的示意图。该装置结构简单，可实现三种运行模式的切换，包括：吸附转轮100、至少一个风机、热源200和控制模块，具体地：
示例地，风机可以包括：送风风机300和排风风机400，控制模块分别与吸附转轮驱动电机、送风风机驱动电机和排风风机驱动电机电连接，从而通过控制吸附转轮驱动电机、送风风机驱动电机和排风风机驱动电机的转速，使得对应的吸附转轮100的转速、送风风机300和排风风机400的风量发生变化，从而能够通过切换热源200和吸附转轮100的转速以及风机实现多种运行模式(如，加湿模式、全热回收模式和自然通风模式三者)之间的自由切换，保证全年舒适节能运行。
在冬季通过开启热源实现加湿，可以显著提升潜热回收效率，从而改善室内干燥的问题；在夏季，调节吸附转轮转速至全热回收模式，降低新风送风温湿度，从而达到节能目的。
控制模块还与热源200电连接，通过调节热源200的功率来改变室外新风的温度。
其中，图1中的OA表示室外新风，RA表示室内回风，SA表示室内送风，EA表示室外排风。热源200、吸附转轮100和送风风机300构成向室内送风的送风通道，室外新风在送风风机300的作用下依次通过热源200和吸附转轮100后进入室内；吸附转轮100和排风风机400构成向室外排风的排风通道，室内回风通过吸附转轮100在排风风机400的作用下排出室外。
处于加湿模式时，将吸附转轮100的转速调节在类等焓调湿模式(相对于全热回收模式而言，如转速在1转/min以下)下，室内回风通过吸附转轮100的吸湿区域，再被排风风机400吸引，排出到室外，该过程中室内回风中的水分被吸附转轮100吸附。室外新风被热源200加热后通过吸附转轮100的放湿区域，经过吸附转轮100后被送风风机300吸引，送至室内。其中，该过程中被加热后的室外新风将吸附转轮100中存储的水分送往室内，实现无水加湿。在该过程中，通过调节吸附转轮的转速，使得室内回风通过吸附转轮时，室内回风中的水分被吸附转轮吸附，被加热后的室外新风将吸附转轮中存储的水分送往室内。
处于全热回收模式时，将吸附转轮100的转速区间调节在全热回收模式下(如转速在5转/min以上)，室内回风通过吸附转轮100时，对吸附转轮100进行显热和潜热交换，再在排风风机400的吸引下排出室外，室外新风通过吸附转轮100时，对吸附转轮100进行显热和潜热交换，再在送风风机300的吸引下排入室内。在该过程中，通过吸附转轮的潜热和显热交换，可以实现室外新风和室内排风之间的全热回收，能够有效降低新风负荷，达到节能目的。
处于自然通风模式时，吸附转轮100停止转动，室内回风和室外新风直接通过吸附转轮100，在排风风机400和送风风机300的吸引下，分别排往室外和室内。在该过程中，通过排风风机400和送风风机300的作用，促进室内空气循环。
如图2所示，为控制模块的结构示意图。控制模块包括：输入端501、电控端502和控制执行器503。其中，输入端501包括：用户侧控制器(如，遥控器)，可作为用户输入和设定端口，以及室内空气传感器和室外空气传感器。
输入端501的信号(如，用户输入的指令信息)和传感器检测到的温湿度信息等，通过电控端502的接收器将指令和信息输送至电控端502，在电控端502由内置的计算程序处理这些指令和信息，从而得到并输出运行模式、时间控制、目标温湿度和未达到目标温湿度等控制执行器503所需的运行指令，由控制执行器503根据对应的运行模式控制热源200、吸附转轮驱动电机、送风风机驱动电机和排风风机驱动电机的运行，从而达到目标温湿度。
具体地，输入端501包括：用户侧控制器、室内温湿度传感器和室外温湿度传感器和其他空气传感器(包括但不限于CO2传感器、PM2.5传感器，甲醛传感器，TVOC传感器等空气品质传感器)，对于获取调节运行模式所需要的其他参数的传感器，在此不做任何限定。用户侧控制器(如，遥控器)可配置成设定运行模式和定时等指令，同时由室内外温湿度传感器发出当前室内外空气条件信息至电控端502的接收器。
电控端502包括：模式控制处理器、计时器、目标温湿度设定器和温湿度控制计算模块。电控端502在接收到输入端501的指令和信息后通过计算处理确定运行模式、目标温湿度以及达到目标温湿度各部件的开关和开度值设定，最后由控制执行器503采取相应的动作。
控制执行器503包括：热源200、转轮驱动电机(即吸附转轮驱动电机)、送风风机驱动电机和排风风机驱动电机。热源200配置成通过调节加热功率改变室外新风的空气温度，在自然通风模式配置成防止冷风直接吹入。送风风机驱动电机和排风风机驱动电机配置成调节风量，转轮驱动电机通过调节吸附转轮100的转速，三者耦合控制，从而实现调节送风温湿度的目的。
在装置正常工作过程中，根据输入端501不断输入的信号，电控端502的计算处理以及控制执行器503的动作实现对室内目标温湿度的控制，实现加湿模式、全热回收模式和自然通风模式三者之间的自由切换。
本申请实施例还提供一种该新风装置的控制方法，可以应用于控制模块，从而实现对新风装置的控制，根据室内外空气环境变化，切换新风装置的运行模式，并在对应的运行模式下，对新风装置进行实时控制。如图3所示，为控制方法的流程图，该方法具体包括以下步骤：
步骤S100：根据用户设定的目标温湿度获取界限温湿度；
如图4所示，为具体的控制过程流程图，首先由用户启动系统，对于运行模式，可 以是用户设定，也可以由系统自行判定即为自动模式。若为自动模式，则通过新风侧温湿度传感器即室外温湿度传感器获取相应的室外温湿度，从而判断相应的运行模式，并发送指令至相应控制执行器503实现模式控制。同时，由电控端502计算目标温湿度，并将指令发往温湿度控制模块。然后，电控端502的温湿度控制模块根据目标温湿度指令和新风/回风侧温湿度传感器(室内外温湿度传感器)信号进行计算，并将执行信号发送至热源200、转轮驱动电机、送风/排风风机400的驱动电机，由此实现对温湿度的控制。
若为用户设定，则用户可以通过用户侧控制器输入设定的目标温湿度，电控侧根据设定的目标温湿度计算出加湿模式下的第一界限温度T_hum和第一界限湿度W_hum，全热回收模式下的第二界限温度T_hr和第二界限湿度W_hr。
步骤S200：接收室内外的温湿度传感器发送的室内外温湿度；
示例地，室外温湿度传感器(新风温湿度传感器)发送的室外温度T_oa，室外湿度W_oa；室内温湿度传感器(回风温湿度传感器)发送的室内温度T_ra，室内湿度W_ra。
步骤S300：比较界限温湿度和室内外温湿度，以确定运行模式；
无论是用户设定或者系统自动设定，对于实际运行模式，需根据下述规则进行判断：
全热回收模式：室外湿度W_oa大于全热回收模式界限湿度W_hr，或者室外温度T_oa与室内温度T_ra之差大于温差T1，即W_oa>W_hr或T_oa-T_ra>T1>0。
加湿模式：室外湿度W_oa小于第一界限湿度W_hum，并且，室外温度T_oa大于加湿功能下限温度T_limit小于室内温度T_ra或者室外温度T_oa大于加湿功能下限温度T_limit小于第一界限温度T_hum，即W_oa<W_hum且(T_limit<T_oa<T_ra OR T_limit<T_oa<T_hum)，其中，T_limit为加湿功能下限温度，例如，设置为0℃(本申请实施例对该加湿功能下限温度不进行具体限制)，当室外温度大于0℃时，才可实现加湿功能。
自然通风模式：以上两个为全热回收模式和加湿模式的条件均不满足，即室内外温湿度不满足上述任一种条件，则为自然通风模式。
步骤S400：在当前运行模式下，根据界限温湿度、室内外温湿度对热源200、吸附转轮100和风机进行控制。
确定运行模式后，在当前运行模式下，进行相应的运行控制。其中空气品质传感器 (如，CO2传感器，还可以为其它空气品质传感器)为选配装置。可通过室内二氧化碳传感器(回风CO2传感器)检测到的室内CO2量CO2_ra对送风量和/或排风量进行相应控制。需要说明的是，本申请中的逻辑控制适用于其他空气品质传感器，在此不做任何限定。
在系统不存在该二氧化碳传感器的条件下，送风/排风量可以根据用户设定进行调节。
全热回收模式：全热回收模式下的转速调节范围可以控制在5转/min-20转/min，在该模式下热源200关闭；吸附转轮100保持高速旋转(如，保持在10转/min以上)，若室外温度与室内温度的差值大于第二预设温差，即T_oa-T_ra>T2，或者室外湿度与室内湿度的差值大于第一预设湿度差，即W_oa-W_ra>W_1，则将吸附转轮100的转速在大于预设的第一转速F1的基础上进行增大；若这两个条件都不满足，则将吸附转轮100的转速在大于预设的第一转速F1的基础上进行减小。
根据室内外温湿度差对吸附转轮100转速进行增大/减小调节，从而提高/减低热回收效率。
在夏季，调节吸附转轮100的转速至全热回收模式，降低室外新风的送风温湿度，从而达到节能目的。
根据二氧化碳传感器或者用户设定调节送风/排风风机400转速。若CO2_ra<CO2，则送风/排风量降低，否则增大，式中的CO2表示用户设定的二氧化碳的预设量值。
加湿模式：类等焓加湿调节范围可以控制在0.1转/min-1转/min(本申请实施例对该转速不进行具体限制)，在该模式下，热源200开启，吸附转轮100保持低速旋转，如保持在1转/min以下，通过室内湿度和第一界限湿度调节热源200的功率。当第一界限湿度与室内湿度的差值小于第二预设湿度差，即W_hum-W_ra<W_2时，增大热源200的功率并且将吸附转轮100的转速在小于预设的第二转速F2的基础上增大；若不满足上述判断条件，则降低热源200的功率，并且将吸附转轮100的转速在小于预设的第二转速F2的基础上降低，如每档设置在0.1转/min，至于降低的方式可以是逐档降低，也可以根据需要连续降低多档，在此不做限定。对于第二转速F2的大小可根据需要进行设定，在此不做任何限定。
热源200的功率增大量，是根据新风温度确定的，热源200的功率为将新风加热至一定再生温度所需的热量，其中，再生温度范围一般在50℃～100℃。
功率＝体积风量*密度*比热*(再生温度-新风温度)，因此，热源200的功率调节幅 度可以根据新风的体积风量和再生温度计算，如100W/档对应于再生温度2℃/档。
在冬季通过开启热源200实现加湿，可以显著提升潜热回收效率，从而改善室内干燥的问题。
在加湿模式下，并没有液态水的产生，无需额外配置冷源，使得装置构造相对简单，可以有效避免有水加湿所带来的水质、安装和维护不便等问题。
根据二氧化碳传感器或者用户设定调节送风/排风风机400转速；若CO2_ra<CO2，则送风/排风量降低，如每档降低50CMH，否则增大，式中的CO2表示用户设定的二氧化碳的预设量值。
自然通风模式：在该模式下，控制吸附转轮100停转；
若室外温度小于预设温度最小值，即T_oa<T_min，则开启热源200并降低送风/排风量，否则关闭热源200，也即根据室外温度决定是否开启热源并确定送风量和排风量的变化。
根据二氧化碳传感器或者用户设定调节送风/排风风机400转速，在此过程中，可以通过比较二氧化碳传感器测得的CO2_ra和预设量值(如，1000PPM，本申请实施例该预设量值不进行具体限制)来调节送风/排风量，也可以通过用户的自行设定调节送风/排风量，在此不做任何限定。若CO2_ra<CO2(表示预设量值)，则送风/排风量降低，否则增大，不仅可以调节室内二氧化碳浓度，也可通过降低送风风机驱动电机和排风风机驱动电机的转速，达到节能目的。
通过该新风装置，可根据室内外环境条件，通过切换热源200和吸附转轮100转速实现多种运行模式加湿、全热回收和自然通风模式的切换，从而保证全年舒适节能运行。
如图5所示，为冬季外界环境低湿工况下，空气焓湿图上加湿模式和全热回收模式的效果对比示意图。从图中可以看出，通过开启热源200，调节吸附转轮100转速，将空气通过转轮呈现近似等焓变化的过程，可以显著提高对于室内回风中水分的回收效率，从而强化加湿效果。同时，由于热源200加热，送风温度同样得到提升，可提高室内温度。
如图6所示，为夏季外界环境高湿工况下，空气焓湿图上除湿模式和全热回收模式的效果对比示意图。从图中可以看出，该两种模式都可以有效降低室外新风湿度，通过室内回风排出室外。但是，开启热源200，将空气通过吸附转轮100呈现近似等焓变化过程时，空气中的潜热转化为显热，送风温度急剧升高，在夏季将直接影响使用感受。 因此，在这种工况下，应调节吸附转轮100转速，使其工作在全热回收模式下，当吸附转轮100的转速增大到10转/min以上时，空气变化过程将偏离等焓过程，呈现两股空气状态直接交换的变化过程，即全热回收模式(显热回收+潜热回收)。
本申请通过调节吸附转轮100的转速，使得装置可以工作在加湿、全热回收和自然通风模式下，也可以在送风侧设置冷源，以降低类等焓加湿后的送风温度。理想情况下，慢速下经过吸附转轮100的除加湿过程呈现等焓变化过程(显热和潜热的交换)，但是由于实际过程中存在热损失，会部分偏离等焓变化过程，因此称为类等焓除加湿。
该装置可在冬季通过开启热源200实现加湿，并可以显著提升潜热回收效率，从而改善室内干燥的问题；在夏季，调节吸附转轮100转速至全热回收模式，降低新风送风温湿度，从而达到节能目的。
此外，在调湿过程中没有液态水的产生，可以有效避免有水加湿所带来的水质、安装和维护等问题。
