Compared with traditional refrigeration and air-conditioning units, it has obvious energy-saving advantages, which can effectively shorten the running time of refrigeration units, reduce operation and maintenance costs, and thus reduce system energy consumption. the

本实用新型的空调机组,采用热回收装置、蒸发冷却装置与机械制冷装置复合的结构,采用转轮式换热器。结构如图1所示,包括机组壳体内平行设置的送风通道和回风通道,第一转轮式换热器3和第二转轮式换热器4设置于送风通道和回风通道中,第一转轮式换热器3和第二转轮式换热器4的新风侧19设置于送风通道中,第一转轮式换热器3和第二转轮式换热器4的回风侧24设置于回风通道中。送风通道内、按新风进风方向依次设置新风口1、圆盘过滤器2、第一转轮式换热器3、第二转轮式换热器4、旋转填料式蒸发冷却器6、表面式换热器7、挡水板a8、送风机9和送风口10,第二转轮式换热器4和旋转填料式蒸发冷却器6之间的机组壳体壁上设置回风口a5;回风通道内、按回风进风方向依次设置回风口b11、过滤网12、直接蒸发冷却器a13、挡水板b14、第二转轮式换热器4、直接蒸发冷却器b15、挡水板c16、第一转轮式换热器3、排风机17和排风口18。
The air-conditioning unit of the utility model adopts a composite structure of heat recovery device, evaporative cooling device and mechanical refrigeration device, and adopts a rotary heat exchanger. The structure is shown in Figure 1, including the air supply channel and the return air channel arranged in parallel in the unit shell, the first rotary heat exchanger 3 and the second rotary heat exchanger 4 are arranged in the air supply channel and the return air channel Among them, the
转轮是一种具有高热回收效率的换热器,它通过内部圆形填料的不断旋转来实现热量传递,具有很大的比表面积,换热效率高、处理的风量范围大、整体性好,布置灵活、传热稳定性好、可控制热回收效率、排风和新风交替逆向流过转轮,具有自净的作用等特点。本实用新型公开的转轮式换热器的结构如图2所示,由转轮式换热器的新风侧19、密封条20、传动装置21、传动皮带22、分隔板23、转轮式换热器的回风侧24和箱体25组成,第一转轮式换热器3和第二转轮式换热器4的新风侧和回风侧之间设置分隔板23,转轮上设置密封条20。图2给出了转轮式换热器3和采用立式布置的结构示意图,转轮式换热器3或4放置在箱体25中,通过箱体壁上固定的传动装置21和传动皮带22带动换热器转动,转轮上设置密封条20,立式布置,布局合理、结构更加紧凑。转轮式换热器无需集中布置,较常规换热器更方便、简单,可长期连续运行,且转轮式换热器布置灵活。温度低(高)的室内排风通过排风侧时,芯材受到冷却(加热)(等湿冷却/加热),及至下一瞬间,刚与排风相接触,被冷却(加热)后的芯材便转到新风区,与进入的新鲜空气相接触。于是,高温(低温)的新鲜空气便得以冷却(加热),即在进行其他热湿处理之前先进行预冷却(加热),从而满足夏季冷回收,冬季热回收的要求。本实用新型采用转轮式换热器取代现有的板翅式换热器,具有热回收效率高,流动阻力小,节能效果显著的特点。

在第二转轮式换热器的新风侧19的通道中布置回风口a5、旋转填料式蒸发冷却器6、表面式换热器7;冬季与夏季都采用一次回风系统,降低了新风负荷;夏季使用低温表冷器起到冷却去湿的作用,冬季使用直接蒸发冷却器起到加湿的作用。

直接蒸发冷却器a13后采用挡水板b14、直接蒸发冷却器b15后采用挡水板c16以控制过水量的问题,防止水滴通过进入回风侧转轮转移到转轮新风侧,从而增加新风的含湿量。 After the direct evaporative cooler a13, the water baffle b14 is used, and after the direct evaporative cooler b15, the water baffle c16 is used to control the problem of water flow, so as to prevent water droplets from entering the return air side runner and transferring to the fresh air side of the runner, thereby increasing the fresh air flow moisture content.
本实用新型结构中的新风过滤器采用的是圆盘过滤器2,室外空气流过圆盘网面时,杂质被阻留在网面上,送风机利用旋转吸嘴吸除阻留在网面上的杂质能过滤空气中的灰尘,对转轮的新风侧进行防尘保护作用,以提高换热器的换热效率并延长其使用寿命;而回风过滤器只采用了过滤网12进行初步过滤,因为在两个转轮式换热器后面均设置了直接蒸发冷却器,直接蒸发冷却器不仅起到了降温作用,而且是很好的湿式过滤器。
The fresh air filter in the structure of the utility model adopts a disc filter 2. When the outdoor air flows through the disc mesh surface, the impurities are blocked on the mesh surface, and the blower uses the rotating suction nozzle to suck out the impurities remaining on the mesh surface. The impurities in the air can filter the dust in the air, and protect the fresh air side of the runner from dust, so as to improve the heat exchange efficiency of the heat exchanger and prolong its service life; while the return air filter only uses the
本实用新型空调机组的工作原理是:室外新风经过圆盘过滤器2将灰尘过滤后,通过第一转轮式换热器3的新风侧,进行第一级等湿降温处理,再经过第二转轮式换热器4的新风侧,进行第二级等湿降温处理,然后与部分室内回风混合经过表面式换热器7进行冷却去湿处理,最后经送风机9将处理后的空气送入室内。室内回风经过滤网12、直接蒸发冷却器a13过滤灰尘的同时降低回风的温度,经过第二转轮式换热器4的回风侧热质交换后,再经过直接蒸发冷却器b15,降低升温的回风温度,经过第一转轮式换热器3的回风侧热质交换后,最终由排风机17将吸收热量的空气排至室外。转轮式换热器的新风侧和转轮式换热器的回风侧在冬季和夏季运行时,作用相反,从而对室外新风进行预热处理,达到热回收的目的。
The working principle of the air conditioner unit of the utility model is: after the outdoor fresh air passes through the disc filter 2 to filter the dust, it passes through the fresh air side of the first runner heat exchanger 3 to perform the first-level equal-humidity cooling treatment, and then passes through the second The fresh air side of the rotary heat exchanger 4 is subjected to second-stage equal-humidity cooling treatment, then mixed with part of the indoor return air and passed through the surface heat exchanger 7 for cooling and dehumidification treatment, and finally the treated air is sent to into the room.
