Abstract

太阳能或空气能地暖系统的管道排空防冻系统包括换热器，单向阀，热水管，排气阀，电磁阀，收缩膨胀箱，冷水管和循环泵组成，其特点是随着循环泵停止运行管路里的水会自动储存于膨胀箱里，保障热量不散失，在冬季又能起到防冻的效果。

Description

太阳能或空气能地暖系统的管道排空防冻系统
技术领域
本发明涉及一种太阳能热水器或空气能的地暖系统。
背景技术
目前，利用太阳能供热的地暖系统以及利用空气能供热的地暖系统，在停机时容易将主机和输水管路冻坏。
发明内容
为了解决上述问题，我们在太阳能以及空气能的地热系统中引入管路排空的方法来解决，在太阳能及空气能供热的地暖系统中，通常采用换热器来进行热量转换。在由换热器，循环泵，输水管路和地热管路组成的密闭循环水路，不断地进行热量传递，在冬季当系统停机时间过长时，换热器及输水管路这些暴露在室外的部分则容易冻坏。
为了解决这个问题，将换热器竖直向上设置，在换热器上部设置一只单向阀，在单向阀的下端并接热水输出管，在热水输出管的室内连接到地热管的地面以上，设置一只四通，在四通的一端设置一只排气阀，在四通的另一端设置一只电磁阀，电磁阀连接一只三通，三通的一端连接一只收缩膨胀箱，三通的另一端连接着另一个三通，另一个三通的一端连接到地热管的回水管，另一端连接冷水管，在冷水管中设置一个循环泵，循环泵将冷水打入换热器里，这样当循环泵工作时，地热管内循环的冷水和收缩膨胀箱里的冷水经过循环泵到达换热器，经过换热后由热水管输出到地热管，热水管里气体经过排气阀排掉，热水经过加热地面后再由循环泵打入换热器完成循环，此时电磁阀关闭。当循环泵停止工作时电磁阀打开，空气由单向阀进入热水管路和换热器，热水由电磁阀流入收缩膨胀箱，冷水由循环泵流入收缩膨胀箱，最终换热器，热水和冷水的水都被储存在收缩膨胀箱里，换热器，冷热水管全部排空。
也就是太阳能或空气能地暖系统的管道排空防冻系统，包括换热器，地暖管，单向阀，热水管，排气阀，电磁阀，收缩膨胀箱，冷水管和循环泵，其特征在于：太阳能或空气能部分产生的热量通过换热器换热给水，循环泵使水在换热器、热水管、地暖管和冷水管之间不断循环；换热器竖直设置，在其顶部的外部设置一只单向阀，在单向阀的下部连接着热水管，在热水管的末端通过一个四通分别连接地暖管的一端、排气阀和电磁阀，在电磁阀另一端通过一个三通分别连接着收缩膨胀箱和冷水管，冷水管分成两路，一路接到地暖管的另一端，另一路连接一只循环泵，循环泵的出口连接到换热器的下端；收缩膨胀箱的膨胀容积P大于等于换热器的容积H加热水管的容积R加冷水管的容积L，即P≥H+R+L，收缩膨胀箱收缩时容积为零。
附图说明
图1是太阳能空气能地热管道排空防冻系统的原理图
在图中1.太阳能或者空气能部分 2.单向阀 3.换热器 4.冷水管 5.热水管 6.循环泵 7.收缩膨胀阀 8.电磁阀 9.排气阀 10.地热盘管。
具体实施方式
如图1所示是一个太阳能加热的地热系统，在图中1是太阳能吸热板，它产生的热量通过换热器3换热，循环泵6使热水在换热器，热水管，地暖管和冷水管之间不断循环，换热器中的热量就不断地循环到地暖管中，循环泵工作时电磁阀8也通电关闭，循环泵同时将收缩膨胀箱吸扁，当系统停止工作时，循环泵停止循环，电磁阀失电而导通，收缩膨胀箱产生负压，空气由单向阀进入热水管，换热器和冷水管中，热水管里的水通过电磁阀进入膨胀箱里，换热器和冷水管里的水也流入膨胀箱里，而地暖盘管处于较低位置液面不发生变动，这时换热器热水管冷水管中都没有水，减少了热量散失冬季又能防冻。当系统再次启动时，电磁阀得电而关闭，循环泵让地暖管中的水流出，同时将膨胀箱里水抽出，热水管中的空气通过排气阀9排出。
