Description

空调房全热回收换气装置
技术领域
本实用新型涉及一种换气装置，尤其涉及一种全热回收换气装置。
背景技术
随着物质生活水平的提高，空调机已成为许多家庭重要的家用电器。但在享受空调给我们带来的舒适的同时，人们也要同时承受空调带来的健康危害。使用空调的房间为防止冷气或暖气散失，门窗会紧闭，房内空气无法与外界对流，因此房间内空气污浊。再加上房间内家具、衣服、杂物散发而积聚的气味、汗味，更让人感觉不适。多种呼吸道疾病、空调病也随之产生。以往人们只有通过打开门窗或使用排气扇等方式使空气对流。由于其排气过程都是把调整成室内条件的空气(如在夏季里经冷却、去湿的室内空气；在冬季经加热、加湿的室内空气)原封不动地向室外排出，所以即使只是短暂的通风，也会造成大量冷气(或暖气)散失，空调电费增加，空调机的负担加重，降低了空调机的使用寿命和房间的空调效果。即使是采用回风系统，也会使部分室内空气排出，仍然造成能源的浪费。
现有的空调房换气装置，以一导热板置于排气管路和进气管路中间，将两者隔开，从而在通风的同时实现室内空气及室外空气的热交换。由于使用导热板进行热交换，换热效果不好，仍存在较大的能量损失，未能真正解决空调房全热回收的问题。
发明内容
本实用新型克服了现有技术的不足，提供了一种使用于空调环境的可连续不断地进行换气，实现全热回收的换气装置。
本实用新型的空调房全热回收换气装置包括室外空气进气口、进气通道、进气风机、室内空气出气口、室内空气进气口、排气通道、排气风机、室外空气排气口和热交换器，其特征在于所述热交换器包括一显热交换器和一潜热交换器，安设于进气通道与排气通道之间，绕轴转动于进气通道与排气通道之间。
在室内空气出气口后，设有一空气加热器。在室外空气进气口后设有一静电除尘器、一活性炭吸附器、一紫外线灯，室内空气出气口设有一负离子发生器，室内空气进气口设有一过滤网。
本实用新型的空调房全热回收换气装置由于设有显热交换器和潜热交换器，换热效果好，能达到排气的全热回收，在实现空调房的空气交换、保持空气流通的同时，能节约能源、减少能耗、减轻空调机的负担。由于室外进气要经过静电除尘器、活性炭吸附器、紫外线灯及负离子发生器等设备，进入室内的空气更干净、清新，有效地降低了呼吸道疾病、空调病等疾病的发生。
附图说明
图1是本实用新型内部结构示意图。
图2是本实用新型显热交换器B向剖视图。
图3是本实用新型潜热交换器A向剖视图。
具体实施方式
实施例1
如图1所示的空调房全热回收换气装置，包括进气系统、排气系统和热交换器。进气系统包括室外空气进气口、进气通道、进气风机、室内空气出气口。排气系统包括室内空气进气口、排气通道、排气风机、室外空气排气口。热交换器包括一显热交换器和一潜热交换器，安设于进气通道与排气通道之间。密封装置6和密封装置17使进气通道和排气通道隔离，防止进气和排气混合，影响热交换的效率及换气的功能。显热交换器和潜热交换器在电机的带动下，绕轴在进气通道和排气通道间转动。如图2所示，显热交换器是采用吸热、散热性能良好的金属或有色金属材料制成，具有蜂窝状通道的圆柱体，其通道的当量直径约为1～2mm。如图3所示，潜热交换器采用吸附氯化锂水化物溶液性能良好的材料制成，如石棉纸、纸、纤维布、毡等，为具有峰窝状通道的圆柱体，其通道的当量直径约为1～2mm，并浸透了氯化锂水化物溶液，这种氯化锂水化物液和结晶在某一温度和湿度的空气中，其水化物溶液和结晶与其周围的空气处于平衡状态，即，氯化锂水化物溶液和结晶中所含的水分与其周围的空气所含的水分相等。因而氯化锂水化物溶液和结晶具有吸湿和散湿的功能。
排气风机把室内气体强制性地由室内空气进气口吸入，经过滤网1后进入排气通道。此时可调通道阀门18处于位置①，室内空气进入显热交换器7，流过蜂窝状的通道，从交换器的一端流向另一端，并在此期间，与交换器进行热交换。室内空气被冷却或被加热，热交换器内介质被加热或冷却。显热交换器7在电动机8的带动下，不断地在排气通道16及进气通道5中转动，排气在这里不断地和显热交换器7进行热交换。为了交换排气中的潜热，被交换了显热的排气，继续进入潜热交换器10。同样，潜热交换器10也在电动机9的带动下，不断地在排气通道16和进气通道5中转动，排气不断地在潜热交换器10中进行潜热交换。交换了全热的排气，其状态接近了室外的空气状态，在离心式排气风机15的作用下，排出室外。同样，室外的新鲜空气在离心式进气风机11的作用下，首先进入静电除尘器13除尘，然后经过活性炭12吸附；紫外线灯14杀菌，沿着进气通道进入潜热交换器。潜热交换器在电动机9的作用下不断地在排气通道16和进气通道5中转动，在排气通道16中吸收了排气潜热的潜热交换器10旋转到进气通道5时，和进气在潜热交换器10进行潜热交换。被进气交换了潜热的交换器回复了初始状态，当回转到排气通道16时，又和排气进行潜热交换。在潜热交换器10内交换了潜热的进气，在进气通道5中进入显热交换器7，在此进一步进行显热交换。被进气交换了显热的显热交换器回复了初始状态，当回转到排气通道16时，又和经过的排气进行显热交换。这样，就使进气和排气通过显热交换器7和潜热交换器10实现不断地全热交换。交换了全热的进气，进入负离子发生器3，进一步净化后由室内空气出气口4进入室内。
实施例2
在实施例1的基础上，于室内空气进气口后安设一空气加热器2。空气加热器2由电阻发热丝或PTC热敏电阻陶瓷制成。在需要除湿时，给空气加热器2通电发热，温度控制在80℃以下，排气风机15使室内高湿度的空气强制性地通过空气加热器时被加热，变成温度转高的空气，这部分被加热的空气由饱和空气变成非饱和空气。此时，可调通道阀门18由位置①转到位置②，将显热交换器7的排气通道关闭，使非饱和的热空气进入潜热交换器10中，吸收潜热交换器10中氯化锂水化物溶液的水分，使氯化锂水化物溶液和结晶同样处于非饱和状态，从而具有很强的吸湿作用。当回转到进气通道5时，从室外吸进的高湿空气，便在潜热交换器10中被吸收了水分，变成了干燥的空气，进入室内。而潜热交换器10中吸收了进气水分的氯化锂水化物溶液变成饱和状态，当进入到排气通道16遇到加热的排气时，又被吸收水分，变成非饱和状态，周而复始，室内的高湿度空气被换成干燥的空气。
