Description

毛细管网仿生空调系统 技术领域
本发明涉及一种对环境温度调节控制的装置，具体是一种毛细管网仿生空调系统，属于空调技术领域。
背景技术
毛细管网用高效利用低品位可再生能源实现环境温度调节，例如用35℃以上温度的水可以采暖，用20℃以下问题的水即可以制冷，其典型结构可以参见申请号为CN200810118238.9的中国专利申请文件。由于节能效益显著，同时具有高舒适度和不占空间的优势，因此，与传统散热器、地板采暖和中央空调相比，毛细管网具有显著的技术优势和经济优势。
申请人在2010年12月21日申请了名称为一种毛细管网空调墙及采用该空调墙的空调系统，其中的空调墙包括承重支撑墙和固定于空调墙内的毛细管网，空调墙还包括被动辐射面，被动辐射面与毛细管网之间、承重支撑墙与毛细管网之间均留有间距不接触；空调系统是以空调墙作为空调末端换热器的空调系统，该空调系统虽然具有诸多优点，但也存在不足，除了空调墙不能移动、维修不便之外，由于毛细管网的供水温度较低，例如通常为5℃左右，因此当冷水进入毛细管网后，存在严重的凝露，如果铺设于地板下，则会对地板造成损伤，如何能在将立式空调柜与地面毛细管网有机结合的同时、能够妥善解决凝露问题，从而提供舒适的恒温环境，成为一大研究课题。此外，毛细管网的制冷速度较慢，也是存在的问题之一。
 技术问题
本发明所要解决的技术问题是针对上述现有技术的问题，提供一种在将空调柜与地暖制冷有机结合的同时，能够妥善解决凝露难题的毛细管网仿生空调系统。
 技术解决方案
为解决上述技术问题，本发明采用的技术方案是：一种毛细管网仿生空调系统，包括具有回风口、出风口的空调柜以及铺设于地面下的地暖制冷单元；所述空调柜内设有位于回风口和出风口之间的第一毛细管网，所述地暖制冷单元设有位于地表下的第二毛细管网；所述空调柜装有引导空气从回风口输入流经所述第一毛细管网后由出风口输出的风机；所述第一毛细管网、第二毛细管网的两端并联在供水管和回水管之间，且至少所述供水管经换热器后接至所述第二毛细管网。
采用本发明的技术方案后，不难理解：通过两并联毛细管网将实现周围环境温度调节的空调柜与地暖制冷单元有机结合起来，借助风机将第一毛细管网自身的辐射换热与空气流动的对流换热相结合，大大提高了温度调节的速度，尤其是采用换热器后，使进入地暖制冷单元的水先与周围空气进行热交换，因此只要合理选择换热面积，即可将水温提高到露点温度以上，从而避免第二毛细管网出现凝露现象，并且该换热器还有助于周围环境温度的调节。
本发明进一步的完善是，所述换热器安置在所述风机的进风口处。这样可以提高换热器的换热效率，更有利于发挥换热器的作用。
本发明再进一步的完善是，所述风机的壳体内具有盘管，所述盘管的两端并联在所述供水管和回水管之间。这样，流经第一毛细管网的空气可以在风机处预先换热，从而进一步提高空调响应速度和工作效率。
 附图说明
图1是本发明一个实施例的系统示意图。
图2是图1实施例的空调柜外形图。
其中：1、柜体，2、回风口，3、出风口，4、供水管，5、回水管，6、第一毛细管网，7、风机盘管，8、接水盘，9、出水口，10、第二毛细管网，11、换热器，12、新风入口。
 本发明的实施方式
下面结合附图，对本发明作详细说明，如图1所示，本实施例的毛细管网仿生空调系统包括立式空调柜以及地暖制冷单元，其中立式空调柜包括内设第一毛细管网6的柜体1，在柜体1的上端具有回风口2以及接外界空气的新风入口12，在柜体1的下端具有出风口3（参见图2）。在柜体1内设置有与第一毛细管网6连接的供水管4和回水管5，在供水管4上接一分水器，在回水管5上接一集水器。在柜体1内还设置有壳体内装有盘管的风机7，在柜体1的下端设置有一冷凝水接水盘8，在该接水盘8上设置有一出水口9。
地暖制冷单元包括第二毛细管网10以及换热器11，其中换热器11优选结构简单的板式换热器，第二毛细管网10的进水口连接供水管，第二毛细管网10的出水口连接回水管5，板式换热器连接在第二毛细管网1的进水口与供水管4之间的管路上，通过板式换热器将供水管路内的7℃左右的供水与周围空气热交换后，转换为15℃～20℃的水进入地暖制冷的毛细管网，防止了毛细管网在地面下的凝露对地板造成的损伤。
风机盘管的两端也连接在供水管4和回水管5上。风机7的出风口设置在第一毛细管网的上端且朝下出风。
工作时，当室内温度达到设定要求或睡眠等需要时，风机停止工作，由毛细管网系统进行非机械运行，只通过辐射调控温度，实现无强风、无污染、无燥音的室内休息环境空调。
与现有技术相比，本实施例的毛细管网仿生空调系统通过风机和毛细管网同时工作，辐射和对流换热相结合，因此显著提高整个空调效率，达到快速制热或制冷的效果。同时，风机内的盘管并联在毛细管网的供水管和回水管上，进一步提高换热效率。地暖制冷单元通过换热器适当提高了进入第二毛细管网的供水温度，有效解决了凝露问题，并有助于改善周围环境温度，一举两得。此外，柜体上设置新风入口使新风从柜体上端进入柜体，在柜内受到第一毛细管网冷辐射的作用，可在一定程度上自动除湿，进一步改善室内环境。
归纳起来，本实施例具有如下主要优点：
1、合理设置换热器，妥善解决了凝露问题。
2、辐射与对流换热结合，显著提高了换热效率。
3、新风置换不但保持空气新鲜，而且有助于促进毛细管网的能量交换。
4、当温度达到恒温控制点或室内需要静音时，风机可自动关闭，实现无强风、无燥声、无污染的高品质环境。
