具体实施方式
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。

可选地，在第一实施例中，空调系统还包括并网换流器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，在第一实施例中，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。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可以采用四象限换流器，也可以采用常规换流器。

结合图1和2所示的第一实施例和第二实施例来说明本发明的空调系统的工作原理和控制过程，当空调系统工作时，针对新型能源80的控制如下：
1、如果新型能源80的能量与空调负载需求匹配时，可以仅采用新型能源为空调供电。
2、如果新型能源80能量大于空调负载需求时，可以采用如下方式控制：
(1)如果系统不包含储能单元90，新型能源80多余能量并网发电；
(2)如果系统包含储能单元90且储能单元90电荷不足需要充电时，新型能源80多余电量首先对储能单元90进行充电，仍有富余时再并网发电；
(3)系统包含储能单元90，储能单元90也可以根据设定的与电网60联动的控制逻辑进行动作。

当空调系统制动或不工作时，新型能源80能量全部进行并网发电，风机10发电电能根据以下情况回收：
1、如果不包含储能单元90时，风机10发电电能通过一定的升压措施或PAWM交错调制等方式进行并网。
2、包含储能单元90时，风机10发电电能进行分级回收：
(1)当风机反转能量小于某一设定阈值时，该能量可以通过储能单元90对应的DC/DC换流器，对储能单元90进行充电，将风机10发电电能通过储存的方式进行回收；
(2)当风机10发电电能达到并网条件时，通过并网换流器50、隔离变压器70(该变压器视电能质量可选择安装)进行并网，供给网内其他负载使用；
(3)当风机10发电电能接近并网条件时，通过一定的升压方式或PAWM交错调制技术等对该能量进行回收并网。
另外，当电网高峰运行或需要支持，同时储能单元90余电充足时，可根据电网调度进行响应，进行错峰调峰运行，为电网安全提供一定的保障。
通过上述控制方式，可以有效解决空调系统风机10发电电能较小的回收问题及在空调工作时不能进行发电的局限，兼顾空调系统供电的多样性，使空调系统尽量实现自给自足，不从市电取电；储能单元90的集成，能够有效提高风机10发电电能回收率及直接利用率，同时对电网提供一定的积极作用。

根据本发明的空调系统，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。
在本发明的上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
