主要特点９�/strong>

◆采用分体式结构，将压缩机、风扇、冷凝器等置于室外，使室内机组结构紧凑、噪音低�

◆合理的水循环使换热器换热效率高，坚固耐用、不易阻塞、抗冻能力强�

◆采用蓄冷动态平衡连续工作方式，因而大大减小了室内机组贮水箱的体积，只需�?0升水就可满足工作要求，且温度控制准确、稳定；

◆操作十分简便，只需按启动开关，机组即进入工作状态；

◆采用温控节点控制自动加热系统，保证北方地区冬季能正常使用；

The structure of SL401 has separation design with compressor� fans� condenser installed outdoors� hence the indoors unit has compact conformation and low noise;

The heat exchanger of this product has well designed water circulation device which increases head exchange efficiency. It has strong robustness� less blocking� and good freezeproofing ability;

This product works on continuously running duty with dynamically balanced cold accumulation� and hence has greatly reduced water storage tank in the indoors unit. Only 60 liters of water is needed to meet the basic work request� and the temperature control is accurate and steady;

The operation of this product is very convenient. Just press the start button� and it will enter work mode.

With the temperature-controlled nodal operation self-heating system� this product can be used in the winter season of north China.
