空调干衣机处于节能降温除湿模式:第一开关关闭、第二开关打开、第三开关打开、第四开关关闭,以使室内空调机2运行制冷模式,室内干衣机1送风;此时,低温冷媒经过室内空调机2给室内降温,冷媒不经过室内干衣机1,干室内干衣机1送风,实现干衣。室内空调机2产生冷量并除湿,以中和室内干衣机1产生的高温髙湿的空气,提高室内舒适度,室内干衣机1仅送风,通过送风实现干衣。
空调干衣机处于极速降温除湿模式:第一开关关闭、第二开关打开、第三开关关闭、第四开关打开,第一节流装置207全开,以使室内干衣机1工 作,室内空调机2处于制冷模式。高温冷媒经过室内干衣机1运行,实现干衣,然后经过第二节流装置202节流降压,低温冷媒经过室内空调机2制冷,实现室内降温。
空调室内机处于恒温恒湿模式,第一开关关闭、第二开关打开、第三开关关闭、第四开关打开,第一节流装置207全开,以使室内干衣机1工作,室内空调机2处于制冷模式。高温冷媒经过室内干衣机1运行,实现干衣,然后经过第二节流装置202节流降压,低温冷媒经过室内空调机2制冷,实现室内降温,室内空调机2平衡室内温度及湿度,保证室内温度波动在2℃以内,湿度控制在65%以内。此时,可控制室外机3的室外风机301停止运转或者低速运转。
温差Tc=室内温度Tr-舒适温度Ts,
-1<Tc<1,转入恒温恒湿模式;
Tc≤-1,转入升温干衣模式;
Tc≥1,转入降温干衣模式。
其中,控制器优选集成在室内空调机中,当然,控制器也可集成在室内干衣机中,或者室内空调机和室内干衣机中均设置有控制器,二者实现相互通信。
其中,舒适温度为用户设定的温度或者事先确定的人体最佳舒适温度。舒适温度为事先确定的人体最佳舒适温度时,空调干衣机根据室内温度、室外温度和确定空调干衣机的运行模式。本实施例在控制器内存储有室内温度、室外温度对应的空调干衣机的运行模式对应表。通过查表获取空调干衣机的运行模式并按照该模式对空调干衣及进行控制。
