本发明原理
本发明中，由发动机组11的曲轴6带动发电机12转动，从而发出高频三相电，经由逆变器转换为220V50HZ单相电，从而给负载提供交流电源。
由发动机组11的曲轴6通过传动机构驱动的压缩机1将气态的空调制冷/制热介质压缩为高温高压的气态空调制冷/制热介质，然后送到冷凝器2散热后成为常温高压的液态空调制冷/制热介质；液态的空调制冷/制热介质经相应的毛细管，进入蒸发器3，空间突然增大，压力减小，液态的空调制冷/制热介质就会汽化，变成气态低温的空调制冷/制热介质，从而吸收大量的热量，蒸发器3变冷，室内机的风机盘管将室内的空气从蒸发器3中吹过，吹出冷风；然后气态的空调制冷/制热介质回到压缩机1继续压缩，继续循环。制热的时候采用常规的选通阀部件，使空调制冷/制热介质在冷凝器2与蒸发器3的流动方向与制冷时相反即可。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
