Description

空调系统 技术领域
本申请涉及空调领域,具体而言,涉及一种空调系统。
背景技术
越来越强烈的环保节能需求,使得无论是家用空调还是商用空调的发展也逐步向变频方向发展。目前,永磁同步风机(即叶轮通过永磁同步电机驱动的风机)已广泛应用于空调器中。针对永磁同步机反向发电的特性,往往需要对空调器的风机进行反向制动控制(软件控制或硬件机械控制)。从而避免空调的室外机中永磁同步风机反转发电带来的电机烧毁的风险,然而设置反向制动控制也导致空调器的故障点增加;另外,风机反转发电产生的能量没有有效回收利用,导致能源浪费。
发明内容
本发明旨在提供一种能够更节能的空调系统。
本发明提供了一种空调系统,包括至少一台风机和至少一台压缩机,空调系统还包括与至少一台风机一一对应连接的至少一台风机换流器和与至少一台压缩机一一对应连接的至少一台压缩机换流器,其中,至少一台风机换流器具有驱动风机的逆变状态和回收风机发电电能的整流状态。
根据本申请的空调系统,通过设置与风机对应的风机换流器,在空调系统工作时,风机换流器工作在逆变状态,驱动风机对空调系统散热,当空调系统停止时,在风机被风驱动发电的情况下,风机换流器工作在整流状态,从而回收电能。即空调系统不工作时,风机成为一台发电机,从而使得空调系统更节能。

具体实施方式
下面将参考附图并结合实施例来详细说明本申请。
如图1所示,根据本申请的空调系统第一实施例,空调系统包括一台风机10和一台压缩机20,空调系统还包括与风机10一一对应连接的风机换流器30和与压缩机20一一对应连接的压缩机换流器40,压缩机换流器40驱动控制压缩机的电机,实现压缩机的变频控制,其中,风机换流器30具有驱动风机10的逆变状态和回收风机10发电电能的整流状态。本申请通过设置与风机10对应的风机换流器30,在空调系统工作时,风机换流器30工作在逆变状态,驱动风机10对空调系统散热,当空调系统停止时,在风机10被风驱动发电的情况下,风机换流器30工作在整流状态,从而回收电能。即空调系统不工作时,风机成为一台发电机,从而使得空调系统更节能。
需要说明的是,本申请提供的实施例中,在空调系统中可以包括:至少一台风机与至少一台压缩机,上述至少一台风机中的每台风机连接一台风机换流器,上述至少一台压缩机中的每台压缩机连接一台压缩机换流器。
优选地,空调系统还可以设置蓄电池,蓄电池与风机换流器30连接,在风机发电过程中,将电能存储,在风机正常工作时,蓄电池提供一部分电能供风机工作。
进一步地,如图1所示,空调系统还可以包括并网换流器50,并网换流器50的第一端与电网60连接,并网换流器50的第二端与压缩机换流 器40和风机换流器30均连接。即可以通过并网换流器50将风机10发电的电能输送到电网上。
优选地,如图1所示,空调系统还包括隔离变压器70,隔离变压器70串联在电网60与并网换流器50之间,串联隔离变压器70能够提高空调系统的安全性,也能够防止干扰。
优选地,并网换流器50为四象限换流器,风机换流器30和压缩机换流器40为可以采用四象限换流器,也可以采用常规换流器。
结合图1来说明本申请的空调系统的工作原理,当空调系统工作时,风机换流器30的DC/AC工作在逆变状态,风机10正转对空调室外机进行散热,空调不工作时(夜晚、冬季等情况),风机10被风驱动发电时,风机换流器30进行反向整流得到直流电。该直流电可以通过一定的升压措施接入直流母线供给母线连接其他负载使用,或通过四象限换流器进行并网供给该电能网络中的其他负载。如果该DC/AC换流环节为四象限换流环节,风机发电可通过该换流环节跟踪母线电压,直接接入直流母线进行并网或供给母线连接其他负载,从而降低电网负荷,使空调器成为一个微型的发电装置,为电网安全提供一定保障。也可以通过蓄电池将电能存储。
如图2所示的第二实施例中,一拖二空调系统采用类似于第一实施例的方式,对应设置风机换流器30和并网换流器50等装置,回收风机发电的电能,从而使得空调系统具有带风力发电功能。
如图3所示的第三实施例中,双风机空调系统也采用类似于第一实施例的方式,对应设置风机换流器30和并网换流器50等装置,回收风机发电的电能,从而使得空调系统具有带风力发电功能。
如图4所示的第四实施例的一拖多空调系统或者如图5所示的第五实施例的多风机空调系统,以及图6所示第六实施例中一拖多并有多台风机的空调系统中均可以采用类似于第一实施例的方式,使得空调系统具有风力发电功能。
从以上的描述中,可以看出,本申请上述的实施例实现了如下技术效果:
根据本申请的空调系统,相比现有技术,通过取消室外机的风机的机 械制动或软件制动部件,并设置与风机对应的风机换流器,在空调系统工作时,风机换流器工作在逆变状态,驱动风机对空调系统散热,当空调系统停止时,在风机被风驱动发电的情况下,风机换流器工作在整流状态,从而回收电能。即空调系统不工作时,风机成为一台发电机,从而使得空调系统更节能。
以上所述仅为本申请的优选实施例而已,并不用于限制本申请,对于本领域的技术人员来说,本申请可以有各种更改和变化。凡在本申请的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本申请的保护范围之内。
